1 INTRODUCTION

This guide is intended to supplement the information presented in the AS/Advanced specification and the specimen papers and marking schemes booklet.

During the Welsh Assembly Government and WJEC sponsored exhibition of candidates' work at the beginning of the Autumn Term each year, the WJEC provides a series of INSET events for teachers delivering this specification in Product Design, Systems and Control Technology. A CD of the project work in the exhibition is also available to all WJEC centres which also contains the presentations given at the training event. Additional INSET provision will be available for teachers of Food Technology.

The WJEC AS and A2 Design and Technology specification has been modified and updated for delivery from September 2008. First examinations at AS level will take place in January and Summer 2009 and the first A2 assessments will take place in January and Summer 2010. The specification can be delivered and assessed in centres throughout the UK.

The revised subject criteria for GCE Design and Technology issued by the regulators have necessitated a change in the course structure from the current 3 plus 3 modules to a 2 plus 2 structure.

This Teachers' Guide is intended to be a support resource and is but one of the many ways in which the WJEC provides assistance to teachers delivering the specification. Other forms of support are: the Specimen Papers; the National Grid for Learning Wales (NGfL Cymru); and INSET conferences.

WJEC provides the following as part of its support for all GCE specifications:

Examiners' reports on each unit examined Free access to past question papers via the WJEC secure website Easy access to the specification and other key documents on the main website Itemised feedback on outcomes for candidates at question level Regular INSET delivered by Chief and Principal Examiners Direct access to both the Subject Officer and to administrative sections

2 AIMS OF THE TEACHERS' GUIDE

The aim of this Guide is to give additional guidance on the whole A level specification with particular reference to detailed planning for the AS course.

The Guide includes examples of how to approach the specification by addressing;

Key features of the whole A level specification The organisation of the whole A level educational programme over two years and

within the AS academic year Possible approaches to the AS Product Design coursework The organisation of work over an academic year Bibliography


3 KEY FEATURES OF THE DESIGN AND TECHNOLOGY SPECIFICATION

Key Features of the Specification

It enables tutors/centres to tailor the specification to suit their expertise and the interests and aptitudes of the students;

It increases stretch and challenge of the topics and assessments over the two years of study;

It allows for creative and innovative technological expression; It makes candidates more aware of Industrial and Commercial practice; It makes candidates aware of sustainability and environmental issues; It enables an awareness of the broader issues related to Design and Technology

and Product Design.

Key Features of AS Level and AL Level

They each consist of two unit courses of study; The coursework aspects will allow students to engage fully in design and make

abilities; They will allow candidates to integrate their knowledge and understanding within

designing and making; Candidates will be involved in manufacturing high quality products which are

appropriate for their intended purpose.


4 MANAGING THE COURSE

Structure of the course

The AS course of study is based on a nine lessons per fortnight plan and should begin at the discretion of individual centres. It also assumes a 40% - 60% time split for designing and making and as such the making activities will need to begin by the end of November at the latest. It also assumes submission of the two AS units at the end of year 12.

It must be emphasized that candidates should ensure sufficient time to undertake a quality evaluation once the product is complete.

An equal time split should also be allocated to the A level course. It is also expected that much of the knowledge and understanding required for the examination will be taught in practical designing and making sessions. Although there may also be a requirement for formal delivery of some aspects of the specification.

A centre may consider entering candidates into the January A/S examination for the Product Design course, which of course will mean a change to the suggested structure.


5 AMPLIFICATION OF DT1 AND DT2

DT1 – WRITTEN PAPER – 40%

DT1 – WRITTEN PAPER – 2 hours

The examination paper DT1 will examine candidates on the following four blocks of specification content:

4.1.1 Designing and Innovation4.1.2 Product Analysis4.2.1 Materials and Components4.2.2 Industrial and Commercial Practice

The blocks of content include specific knowledge and understanding, which are set out in the specification, and form the basis for setting the examination paper. Much of this knowledge and understanding will, of course, be directly relevant to many aspects of the AS coursework elements. It is anticipated that the content of the specification will be presented to candidates in practical designing and making sessions as well as in more formal theoretical lessons.

Unit DT1 consists of three separate papers – one for each focus area. Candidates attempt only one paper, which will consist of two sections:

Section A: This will contain eight short answer questions out of which the candidate will be required to answer 5 questions. It is expected that each answer would be approximately 150 words (with sketches where appropriate) or half a side of A4 and would address the knowledge and understanding contained within the four DT1 units of study. This section is intended to examine the candidates' breadth of knowledge. Answers in this section could be in standard prose or in the form of a comparative table or chart, depending on the nature of the question. Each question will be worth eight marks, giving a total of 40 marks for Section A

Section B: This section will contain three questions which will examine the depth of knowledge and understanding gained over the duration of the Advanced Subsidiary course. Candidates will be required to produce one longer essay type response to these questions which will be allocated 30 marks, including credit for quality of written communication.

Candidates must use an essay structure to convey their section B answer, this will provide evidence of extended prose within the response to allow the 'quality of communication' marks to be awarded.

It is suggested that candidates spend no more than 15 minutes per answer on Section A and the remainder of the time, 45 minutes, on the essay in Section B.

Examples of the type of question included in the current DT1 and DT4 examinations can be obtained as past papers which are available from the WJEC Bookshop 029 2026 5112 or the WJEC web site (www.wjec.co.uk). Marking schemes are available from the WJEC Bookshop.

http://www.wjec.co.uk/


Centres may find it helpful to use questions from previous examination papers when preparing candidates for current examinations as the style of the questions will remain the same.

DT 2 - The Design and Make project – 60%

This part of the DT2 unit should give candidates an opportunity to apply knowledge and skills to solve a real problem at AS level and also to prepare candidates for the AL design project (DT4). Careful consideration should be given to the size of the project in terms of work demands so that it does not become a burden on the candidate in terms of the overall AS time commitment.

Although not mandatory it is suggested that candidates should begin to use A2 size paper for the coursework, as a preparation for the AL project. That being the case the following guide should give a clear indication of the amount of design work which is expected, from the majority of candidates.

(i) Research and analysis - 4 sheets(ii) Design Brief and specification - 1 sheet(iii) Design considerations and investigation - 3 sheets(iv) Generating proposals - 4 sheets(v) Development details - 2 sheets(vi) Detail designing - 2 sheets(vii) Planning/Quality Assurance/Quality Control - 1 sheet(viii) Evaluation - 2 sheets

These figures are given as an approximate guide only – examiners will assess the design and make task against the published assessment criteria rather than by the number of design sheets or report pages. It is suggested that, as an alternative to including material in the A2 sized design folio, the planning, section and use of materials, evaluation and economic factors (costings) content could form the basis of an A4 project report as described at the end of this resource.

The Sketchbook.

Within part (c) of the assessment criteria for 'designing' there is reference to the candidate's sketchbook. It is intended that this sketchbook should be directly linked to the design and make task, where candidates have the opportunity to think creatively and fluently around the problem irrespective of presentation constraints.

It is important that candidates are made aware of the informal nature of the sketchbook and the opportunities that it can afford for creative design. Though clear communication (including appropriate annotation) in the form of line drawings is expected, there is no requirement for elaborately finished presentation drawings, which could impinge on time and creativity, to be included within the sketchbook.

7 DESIGNING AND MAKING WITHIN DT2 & DT4

INTRODUCTION

At both AS and AL, candidates are required to integrate their knowledge and understanding with designing, making and Key Skills to produce high quality products which are appropriate for their intended purpose. A design project (within DT2 or DT4) is the evidence that candidates provide for assessment at AS/AL. As such the projects should be constructed around the assessment criteria for Designing and Making thereby ensuring that candidates have met all the demands laid out in the subject specification.

It is only possible for moderators to allocate marks for the evidence that is presented to them.

Providing Evidence

The checklists, which follow, will provide candidates with guidelines of what moderators are expecting to see as a result of the work undertaken on the project. This list is by no means exhaustive and candidates may wish to consider additional factors. Designing is rarely seen as a linear process; it can be cyclical, iterative or expanding as appropriate to the particular circumstances.

It is also important to note that not all aspects indicated below need to be addressed by any particular design task. The Aide-Memoir provided below will allow candidates to check whether they have overlooked a piece of work, if so, they may then complete it and insert it into their design folder or project report. Their work can then be measured against the assessment criteria.

DT2 DESIGN CHECKLIST FOR PROJECT ASSESSMENT

DESIGNING – Analysis and research

(a) Product Analysis and research 20 marks

No analysis or little analysis of a product or range of products, which does not help to focus the research.

Analysis limited or inappropriate.

Major parameters for the product superficially outlined.

0 – 4

Some analysis of the product.

Some evidence of focused research activity with some important factors considered in the product analysis both 'above' and 'below the line'.

5-10

A product analysis which has led to a clear understanding of the major requirements to be met both 'above' and 'below the line'.

Research is appropriate and wide-ranging, meeting the needs of the target audience.

11 – 15

Detailed product analysis has led to appropriate and well-focused research.

The intended product has been carefully analysed for, 'above' and 'below the line' criteria.

The candidate has demonstrated a thorough understanding of the task ahead and the requirements which have to be met to satisfy the needs of the target audience.

16 – 20


Analysing and researching design situations

There is a greater assessment weighting for the analysis at A/S level and this greater weighting means that moderators are looking for greater depth of knowledge of the design problem derived from a broad analysis. At this point in their designing candidates must demonstrate a divergent approach to problem identification.

This could be initiated as a diverse spray diagram developed from an understanding of the problem parameters followed by focused research of relevant aspects of the problem. The analysis must be 'lean' including all aspects of the problem and with little superfluous information. It is important that all research is relevant and will provide material that will be useful when considering the development of a specification and idea generation.

It is essential that candidates reflect upon their research to determine the extent of their knowledge and understanding of the nature of the problem that they are faced with. Also that they are aware of the needs of their target audience and that their design thinking is directed at them.

Checklist of features

Identifying a need

Explain the following to define the design situation clearly in words and drawings/photographs:

what are the aims of the project; who is the product intended for, the target audience; how often is the product likely to be used; where will the product be used; will the existing environment affect the design of the product?

Identify user needs

list all the qualities that you think the intended user may demand of your product; undertake market research on your target audience to establish their

wants/needs; present a comparative analysis of your results.

Evaluating existing products

use your specification to evaluate existing products; present a range of existing products; explain why you chose the particular products for evaluation (target audience,

market sector etc.); annotate the important design features of the products; annotate the weak design features of the products; explain why existing products might not fulfil the wants/needs of your target

audience.


Design considerations

produce a 'mood, theme and/or lifestyle board' for your design work; explain the design features that you think your product must have; assess the importance of a range of design considerations to your design

task; describe any unique selling points or special features that your product might

have.

Research

identify relevant knowledge and understanding that you will need to help you when designing;

identify the likely sources of this information; include a section in your folio that contains the information that you intend

using; place other material in a separate ring binder or document wallet.

DESIGNING – Developing a specification

(b) Developing a specification 10 marks

The specification displays a hierarchy of criteria, some of which are measurable.

6 – 8

A detailed and relevant specification developed from the product analysis

The specification displays a hierarchy of criteria, some of which are measurable and take account of the relative importance of a wide range of factors.

9 – 10


Developing a Specification

Candidates must realise that an extended specification must be continually used as a design tool to measure the viability of potential ideas. Evidence of the use of the specification must be provided in design thinking. The specification should take account of a wide range of factors, sufficient to result in a quality solution to the problem and candidates should also include a mix of qualitative and quantitative criteria.

It is important when candidates develop their specification that they realise that it is probable that other features could be included as they progress along the problem solving route. This further exemplifies the iterative nature of designing. The specification must address the needs of the target audience and as such should include the essential features of the anticipated product. It should also include unique selling points of the intended outcome.

The specification may be written as short phrases as these are able to be kept in mind whilst designing. However, these bullet points must be fully described to ensure clarity for other readers and to communicate the exact nature of the specification point.

Candidates should also bear in mind the extent and quality of the specification as it will later be used as a guide to measure the quality of the product when evaluating it.


Design brief and specifications

write an initial design brief as a short, clear statement of intent; make a detailed broad product specification; include specifications required by the client or consumer; develop a hierarchy of features; use qualitative and quantitative performance criteria; include the unique selling points of the product.


DESIGNING – Generating and Developing Ideas and Proposals

(c) Generating and developing ideas and proposals 20 marks

analysing and developing ideas. A diverse range of initial ideas are used to build towards a proposal that

fully meets the previously identified specification. Development and refinement design details that identify important

factors in the evolution of the product.

16 – 20


Generating and Developing Ideas and Proposals

It is important that candidates begin to use sketchbooks to bring their thoughts into reality as quick freehand line drawings initially where they can then be worked upon to develop greater clarification of the design insight. It is here that they can blast ideas and suggest forms of the solution without the presentation constraints that can constrict creative idea generation.

These ideas or suggestions can then be further developed in the design folio in order to assess their viability and to make decisions about their possible selection for further design development. The use of ICT, vector design software or solid modeling software, in early idea generation is to be encouraged if it leads to a greater understanding of the form or features of the product.

Supplementary to design drawings of course are three dimensional models or mock-ups. Candidates are encouraged to 'get into 3D'; as soon as possible. Nothing tells the designer more about shape, form and proportion than a scale model using appropriate materials to produce a quick resulting model.

When candidates work up possible ideas to test their viability it is important that they use information gained during their research and that the specification is impacting upon their designing. Moderators will be looking for this particularly when awarding the higher range of marks.

From the 'light touch' of knowledge used in initial ideas candidates should now be getting much more specific as their optimum solution evolves. This is where they now begin to converge upon a definite proposal. As such, the quality of detail related to the solution should be getting more precise. Material selection and manufacturing processes should be identified along with exact constructional details and probable finishes. Of course, these should match the design specification.


Generating design ideas

produce a comprehensive range of initial ideas with mini-development; include material considerations and possible construction techniques; annotate your design ideas indicating the strengths and weaknesses of these

ideas; use your specification to assess the strengths/weaknesses of your idea; identify ideas, or parts of the ideas, that can benefit from further development; say why you think that these ideas have potential for further development; explain why your other designs may not be as successful; make models or mock-ups as appropriate to prove and test your ideas.

Development of chosen idea using ICT where appropriate

show clearly which idea you have chosen to develop; integrate aspects of other proposals that would improve the product; apply anthropometric data and explain why this is essential; develop a detailed design proposal for prototyping; explain all constructional details; establish suitable materials and possible alternatives; identify components and fixings that would be needed; evaluate the strengths of the proposal against the specification.


DESIGNING – Detail Designing

(d) Detail designing 15 marks

Effective presentation of the proposal which communicates design intentions to prospective client/s.

The solution fully meets the requirements set out in the design specification.

Appropriate ICT skills have been used to present detailed dimensions and the final proposal.

13 – 15


Detail Designing

Candidates must present a fully developed solution identifying appropriate materials and manufacturing techniques indicated in detail sufficiently clear to be made by a third party without further reference to the designer. However, if there are some fine details, such as fillets or radii, that are not critical to the construction or function of the intended product then candidates will not lose marks as a result. The details of the final solution must also meet the requirements set out in the specification. Candidates should produce presentation drawings and client visuals including an appropriate range of graphic techniques. Colour should be used judiciously to demonstrate shape and form and to assist in high quality communication of detail. Although not a test of literacy poor quality of written communication may influence the quality of this detail. Where appropriate the use of ICT can be very beneficial here, as candidates can use the parametric nature of solid modelling software to fully dimension parts and produce rendered images of the final design.

If the solution is to be a model then there must be client concept boards, costings and a business plan for the anticipated product or development. The business plan and concept boards are marked in this section.

Candidates working in textile materials must produce toiles, full sized patterns with constructional annotation and presentation visuals.


Formal presentation drawings using ICT where appropriate

detail drawings in orthographic projection as appropriate; produce parts drawings if required; provide section and/or exploded drawings as appropriate; pictorial rendered drawings; produce a cutting list including materials and other remarks; list any components and fixings to be used; provide patterns or templates as appropriate.


DESIGNING – Evaluation, reflecting and decision making

Summative well-written reflective evaluation which makes detailed reference to the specification and the performance criteria.

9 – 10


Evaluation, reflecting and decision making

Candidates should comment objectively on each of the specification points. It is important that candidates use every feature of the specification as evaluation criteria with which they can measure the success of their end product. They should also comment upon any modifications that should be made as a result of this summative evaluation.

They should also provide evidence of end testing which can be undertaken by themselves in many circumstances. However, if the product has been designed for a target audience, it is members of that target audience that should undertake the testing, e.g. children's toys.

They should also seek the views of specialists in the field as to the quality of the product against the specification.


Evaluating proposal against product specification

list the specification points; evaluate your product against each specification point; use your qualitative and quantitative performance criteria; show a photograph of the chosen product/system.

End testing

devise suitable methods of end testing; carry out tests on your product/system; record your findings including photographs; get an end user, from your target audience, to perform a user trip and

evaluate the product in use; seek expert opinion on your product; use feedback to evaluate the product against the performance specification.

Suggestions for modifications

list all aspects of the design that require modification; produce drawings to show the possible modifications; if possible carry out modifications; obtain feedback on suggested or actual modifications and present this in your

project report.

* record all aspects of the evaluation in your project report.


DESIGNING – Communication / Key skills

(f) Communication / Key skills 10 marks

Written communication demonstrates clarity, accuracy and depth of understanding.

Very good use of appropriate ICT, and relevant helpful numeracy.

9 – 10


Communication / Key skills

Candidates should present an organised portfolio supported by a comprehensive sketchbook. The sketchbook will be an important feature of the candidates' thinking skills. This should also contain sufficient annotation or labelling to aid the candidate when returning to early intentions.

The design portfolio should also demonstrate a range of graphic techniques such as perspective drawing, section drawing, orthographic sketches, exploded sketches, parts sketches, etc.

Colour should be used to demonstrate form and texture of products and should be used to clarify design proposals. The particular rendering strategy and media used by the candidate should be what they are comfortable with.

It is important that candidates written communication is clear and accurate in conveying information and that relevant use of numeracy also aids communication.

Wherever possible candidates should make use of ICT and the many software packages available to them to assist in effective high quality communication.


Product planning

organised portfolio is easy to read and communicates effectively; there should be a range of graphic techniques used; colour should be used to define form and texture; numeracy and written communication should be clear and accurate; ICT should be used where appropriate and effective.


MAKING – A CHECKLIST FOR PROJECT ASSESSMENT

It is important to remember that, as for the 'designing' checklist presented above, not all aspects indicated as checklist features below need to be addressed by any particular product. However, the assessment criteria must be met if candidates wish to maximize their potential.

MAKING - Planning for Making

(g) Planning for making 5 marks

Little evidence to support planning for production of the product.

Limited evidence of quality assurance and quality control measures.

1

Some use made of project management systems for production of the product.

Some quality assurance and quality control measures are in place.

2

Use made of appropriate project management systems for production of the product.

Quality assurance and quality control measures are in place.

3 - 4

Thorough planning for production of the product using effective and appropriate project management systems.

Detailed quality assurance and quality control measures are in place.

5

Planning for making

Moderators will be looking for evidence of planning that has developed before making begins as well as throughout the making process. Quality assurance features should be listed before making begins, e.g. materials of required quality chosen beforehand, manufacturing processes refined to ensure quality, etc.

Quality control features are identified and operated when making critical components. These should be recorded in the candidates' journal.

Forward planning of making activities may be recorded week by week in the candidates' journal. It could be that candidates record the progress of their making in the sketchbook. Any modifications required to the design proposal during the making stage can then be recorded in the relevant planning section.


Checklist of features.

Product planning

produce a production plan for the product; consider quality assurance and quality control procedures; list the construction stages for each component; include the joining and assembly stages; estimate the time requirements for each operation and include this in your

production plan; identify tools, equipment and processes needed; identify your personal training needs.

* record all planning details in your project report.

Costing

labour and stock material costs; outline unit part costs; fixtures, fittings and/or other bought in components; total prototype unit cost; cost of manufacturing batch products where appropriate.

* record costing details in your project report.

MAKING – Selecting and testing materials and processes

Selecting and testing materials and processes

Moderators will assess the appropriateness of the materials selected for particular components against the function of the component. They will also judge the appropriateness of the materials against the environment that the product will operate.

Candidates will also be expected to undertake 'fair' tests on critical components to ensure that they will be able to take the loads for which they were designed.

The other aspect in this will be the consideration given to the selection of materials against relevant criteria. This can be in the form of a table as indicated.

DT4 Details of Assessment Criteria

DESIGNING Mark Range

(a) Analyse research and developing a design specification 10 marks

No analysis or little analysis of the situation which does not help to focus the research.

Research limited or inappropriate.

Major parameters for the product superficially outlined.

0 – 2

Some analysis of the situation. Some evidence of research activity with some important factors considered.

A specification developed to a level of detail sufficient for the development of a solution but lacking a number of important performance criteria which influences design decisions.

Evidence of students' ability to reflect upon their research and analysis and make objective comment on the way forward.

A detailed and relevant specification which displays a hierarchy of measurable criteria which take account of the relative importance of a wide range of factors which will drive designing.

9 – 10

Analyse research and developing a design specification

There is a lesser assessment weighting for the analysis at A Level however, moderators are looking for a similar depth of knowledge of the design problem derived from a broad analysis. At this point in their designing candidates must demonstrate a divergent approach to problem identification.

This could be initiated as a diverse spray diagram developed from an understanding of the problem parameters followed by focused research of relevant aspects of the problem. The analysis must be 'lean' including all aspects of the problem and with little superfluous information. It is important that all research is relevant and will provide material that will be useful when considering the development of a specification and idea generation.


It is essential that candidates reflect upon their research to determine the extent of their knowledge and understanding of the nature of the problem that they are faced with. Also that they are aware of the needs of their target audience and that their design thinking is directed at them.

Candidates must realise that an extended specification must be continually used as a design tool to measure the viability of potential ideas. Evidence of the use of the specification must be provided in design thinking. The specification should take account of a wide range of factors, sufficient to result in a quality solution to the problem and candidates should also include a mix of qualitative and quantitative criteria.

It is important when candidates develop their specification that they realise that it is probable that other features could be included as they progress along the problem solving route. This further exemplifies the iterative nature of designing. The specification must address the needs of the target audience and as such should include the essential features of the anticipated product. It should also include unique selling points of the intended outcome.

The specification may be written as short phrases as these are able to be kept in mind whilst designing. However, these bullet points must be fully described to ensure clarity for other readers and to communicate the exact nature of the specification point.

Candidates should also bear in mind the extent and quality of the specification as it will later be used as a guide to measure the quality of the product when evaluating it.


Identifying a need

Explain the following to define the design situation clearly in words and drawings/photographs:

what are the aims of the project; who is the product intended for, the target audience; how often is the product likely to be used; where will the product be used; will the existing environment affect the design of the product?

Identify user needs

list all the qualities that you think the intended user may demand of your product; undertake market research on your target audience to establish their

wants/needs; present a comparative analysis of your results.

Evaluating existing products

use your specification to evaluate existing products; present a range of existing products; explain why you chose the particular products for evaluation (target audience,

market sector etc.); annotate the important design features of the products; annotate the weak design features of the products; explain why existing products might not fulfil the wants/needs of your target

audience.


Design considerations

produce a 'mood, theme and/or lifestyle board' for your design work; explain the design features that you think your product must have; assess the importance of a range of design considerations to your design

task; describe any unique selling points or special features that your product might

have.

Research

identify relevant knowledge and understanding that you will need to help you when designing;

identify the likely sources of this information; include a section in your folio that contains the information that you intend

using; place other material in a separate ring binder or document wallet.

Design brief and specifications

write an initial design brief as a short, clear statement of intent; make a detailed broad product specification; include specifications required by the client or consumer; develop a hierarchy of features; use qualitative and quantitative performance criteria; include the unique selling points of the product.

16 – 22

A wide range of appropriate designing skills within a sketch book which includes, annotation, quick idea generation and evaluative comment related to the design brief.


Modelling and testing aids innovative decision making. Clear reference is made to the specification through annotation when

analysing and developing ideas. A diverse range of initial ideas are used to build towards a proposal that

fully meets the previously identified specification. Develop and refine design details that identify important factors in the

evolution of the product.

23 – 30


Generating and developing innovative ideas and proposals

It is important that candidates use sketchbooks to bring their thoughts into reality as quick freehand line drawings initially where they can then be worked upon to develop greater clarification of the design insight. It is here that they can blast ideas and suggest forms of the solution without the presentation constraints that can constrict creative idea generation.

These ideas or suggestions can then be further developed in the design folio in order to assess their viability and to make decisions about their possible selection for further design development. The use of ICT, vector designs or solid modeling, in early idea generation is to be encouraged if it leads to a greater understanding of the form and/or features of the product.

Supplementary to design drawings of course are three dimensional models or mock-ups. Candidates are encouraged to 'get into 3D'; as soon as possible. Nothing tells the designer more about shape, form and proportion of a design idea than a scale model using appropriate materials to produce a quick model.

When candidates work up possible ideas to test their viability it is important that they use information gained during their research and that the specification is impacting upon their designing. Moderators will be looking for this particularly when awarding the higher range of marks.

From the 'light touch' of knowledge used in initial ideas candidates should now be getting much more specific as their optimum solution evolves. This is where they now begin to converge upon a definite proposal. As such, the quality of detail related to the solution should be getting more precise. Material selection and manufacturing processes should be identified along with exact constructional details and probable finishes. Of course, these should match the design specification.

The increased weighting in this section should be reflected in the quality of creative designing and innovative steps towards the optimum solution.


Generating design ideas

produce a comprehensive range of initial ideas with mini-development; include material considerations and possible construction techniques; annotate your design ideas indicating the strengths and weaknesses of these

ideas; use your specification to assess the strengths/weaknesses of your idea; identify ideas, or parts of the ideas, that can benefit from further development; say why you think that these ideas have potential for further development; explain why your other designs may not be as successful; make models or mock-ups as appropriate to prove and test your ideas.

Development of chosen idea using ICT where appropriate

show clearly which idea you have chosen to develop; integrate aspects of other proposals that would improve the product; apply anthropometric data and explain why this is essential; develop a detailed design proposal for prototyping; explain all constructional details; establish suitable materials and possible alternatives; identify components and fixings that would be needed; evaluate the strengths of the proposal against the specification.


DESIGNING - Detail designing

The solution fully meets the requirements set out in the design specification.

9 – 10


Detail Designing

Candidates must present a fully developed solution identifying appropriate materials and manufacturing techniques indicated in detail sufficiently clear to be made by a third party without further reference to the designer. However, if there are some fine details, such as fillets or radii, that are not critical to the construction or function of the intended product then candidates will not lose marks as a result. The details of the final solution must also meet the requirements set out in the specification. Candidates should produce presentation drawings and client visuals including an appropriate range of graphic techniques. Colour should be used judiciously to demonstrate shape and form and to assist in high quality communication of detail. Although not a test of literacy poor quality of written communication may influence the quality of this detail. Where appropriate the use of ICT can be very beneficial here, as candidates can use the parametric nature of solid modelling software to fully dimension parts and produce rendered images of the final design.

If the solution is to be a model then there must be client concept boards, costings and a business plan for the anticipated product or development. The business plan and concept boards are marked in this section.

Candidates working in textile materials must produce toiles, full sized patterns with constructional annotation and presentation visuals.


Formal presentation drawings using ICT where appropriate

detail drawings in orthographic projection as appropriate; produce parts drawings if required; provide section and/or exploded drawings as appropriate; pictorial rendered drawings; produce a cutting list including materials and other remarks; list any components and fixings to be used; provide patterns or templates as appropriate.

Summative well-written reflective evaluation which makes detailed reference to the specification and the performance criteria.

12 – 15


Evaluation, reflecting and decision making

Candidates should comment objectively on each of the specification points. It is important that candidates use every feature of the specification as evaluation criteria with which they can measure the success of their end product. They should also comment upon any modifications that should be made as a result of this summative evaluation.

They should also provide evidence of end testing which can be undertaken by themselves in many circumstances. However, if the product has been designed for a target audience, it is members of that target audience that should undertake the testing, e.g. children's toys.

They should also seek the views of specialists in the field as to the quality of the product against the specification. These three key evaluative strategies should be evident to gain maximum marks.


Evaluating proposal against product specification

list the specification points; evaluate your product against each specification point; use your qualitative and quantitative performance criteria; show a photograph of the chosen product/system.

End testing

devise suitable methods of end testing; carry out tests on your product/system; record your findings including photographs; get an end user, from your target audience, to perform a user trip and

evaluate the product in use; seek expert opinion on your product; use feedback to evaluate the product against the performance specification.

Suggestions for modifications

list all aspects of the design that require modification; produce drawings to show the possible modifications; if possible carry out modifications; obtain feedback on suggested or actual modifications and present this in your

project report.

* record all aspects of the evaluation in your project report.

Communication / Key skills

Candidates should present an organised portfolio supported by a comprehensive sketchbook. The sketchbook will be an important feature of the candidates' thinking skills. This should also contain sufficient annotation or labelling to aid the candidate when returning to early intentions. It should contain all other ancillary materials such as photographs, magazine cuttings, swatches, etc.

The design portfolio should also demonstrate a range of graphic techniques such as perspective drawing, section drawing, orthographic sketches, exploded sketches, parts sketches, etc.

Colour should be used to demonstrate form and texture of products and should be used to clarify design proposals. The particular rendering strategy and media used by the candidate should be what they are comfortable with.

It is important that candidates written communication is clear and accurate in conveying information and that relevant use of numeracy also aids communication.

Wherever possible candidates should make use of ICT and the many software packages available to them to assist in effective high quality communication.


Product planning

10 AMPLIFICATION OF DT3 & DT4

DT3 – WRITTEN PAPER - 20%

Examination paper DT3 will examine candidates on all eight blocks of specification content:

the four AS blocks;

4.1.1 Designing and Innovation4.1.2 Product Analysis4.2.1 Materials and Components4.2.2 Industrial and Commercial Practice

and the four A Level (A2) blocks;

4.1.3 Human Responsibility4.1.4 Public Interaction4.2.3 Processes4.2.4 Production Systems and Control.

The blocks of content include specific knowledge and understanding, which are set out in the specification, and which will form the basis for setting the examination paper. Much of this knowledge and understanding will, of course, be directly relevant to many aspects of the AS and A2 coursework elements. It is anticipated that the content of the specification will be presented to candidates in practical designing and making sessions as well as in more formal theoretical lessons.

Unit DT3 consists of three separate papers – one for each focus area. Candidates attempt only one paper, which will consist of three sections:

Section A: This will contain five short answer questions out of which the candidate will be required to answer 3 questions. It is expected that each answer would be approximately 150 words (with sketches where appropriate) or half a side of A4 and would address the knowledge and understanding contained within the four A2 units of study (4.1.3, 4.1.4, 4.2.3, 4.2.4). This section is intended to examine the candidates' breadth of knowledge and answers in this section could be in standard prose or in the form of a comparative table or chart, depending on the nature of the question. Each question will be worth eight marks, giving a total of 24 marks for Section A.

Section B: This will contain six short answer questions out of which the candidate will be required to answer 3 questions. It is expected that each answer would be approximately 150 words (with sketches where appropriate) or half a side of A4 and would address the knowledge and understanding across the whole specification (i.e. it is synoptic in nature). This section is also intended to examine the candidates' breadth of knowledge and answers in this section could be in standard prose or in the form of a comparative table or chart, depending on the nature of the question. Each question will be worth eight marks, giving a total of 24 marks for Section B.


Section C: This synoptic section will contain five questions which will examine the depth of knowledge and understanding gained over the duration of the whole course. Candidates will be required to produce two longer essay type responses, each taking approximately 30 minutes. These questions will be allocated 26 marks each, including credit for quality of written communication, giving a total of 52 marks for Section C.

Candidates must use an essay structure to convey their section C answer, this will provide evidence of extended prose within the response to allow the 'quality of communication' marks to be awarded.

It is suggested that candidates spend no more than 1½ hours on Sections A and B and the remainder of the time, 1 hour on Section C.

Examples of the type of question included in the DT1 and DT4 examinations can be obtained as past papers which are available from the WJEC Bookshop 029 2026 5112 or the WJEC web site (www.wjec.co.uk). Marking schemes are available from the WJEC Bookshop . Centres may find it helpful to use questions from previous examinations papers when preparing candidates for current examinations as the style of the questions will remain the same.

DT4 - PROJECT 30%

This project should represent about 60 hours of supervised time, however as with all other Advanced Level subjects, candidates will need to work independently and outside of supervised time to complete the work to an appropriately high standard. In terms of time, demands and complexity, this project is very similar to that required by the previous A Level syllabus which was examined for the last time in 2008. The work presented for DT4 must be distinctly different and separate from that submitted for DT2, whether the submissions are made in the same or different examination sessions.

DT4 project work must demonstrate the candidate's ability to:

1. design and make high quality products which can be tested and evaluated;

2. apply relevant knowledge and understanding including key skills to a range of technological activities;

3. relate their work to relevant industrial and commercial practices;

4. communicate to relevant audiences their ideas, understanding and decision-making processes.

These competencies at Advanced Level would demonstrate a greater depth and maturity to candidates' designing and making skills, appropriate to an A Level qualification.

Differentiating DT2 and DT4: the further requirements at A level involve increased emphasis on the industrial and commercial aspects of designing and making, an increased awareness of a wider range of users such as clients, manufacturers and the potential end user and an increased sensitivity to the wider effects of their work on society and the environment.

http://www.wjec.co.uk/


Candidates are required to submit a single, substantial project for assessment in DT4. The project is to consist of a design folio, sketchbook and the associated outcome. Each year the WJEC will set eight themes for the project, which will allow candidates to work in one of the focus areas of product design, food technology or systems and control technology. Candidates may, if they wish, submit their own proposals (question 9) for the approval of the Chief Examiner providing they are based within one of these focus areas and reflect the spirit and content of the specification. These submissions should be made on form DT4 and sent to the WJEC by 30th September at the latest, in the year preceding the examination.

Question 9 exists to allow candidates equality of opportunity for undertaking interesting, motivating project work should they not be inspired by the eight set themes. Considerable care should be taken when advising candidates with regard to their own submission, which should be derived from their own analysis of a design situation. Experience has shown that simply allowing candidates to work on previous year's set questions, with access to previous research/investigation/resources is not conducive to the production of innovative, high scoring work.

Candidates may respond using ICT in their work in DT4, as appropriate to their requirements, providing the published assessment criteria for these components are met.

UNIT DT4 ( 30% AL)Design and Make task

Designing 75 marks

Making 75 marks

Sub-Total 150 marks

It is suggested that approximately 60 hours is devoted to the Design and Make task. Candidates are expected to demonstrate achievement and abilities appropriate for the second year of an AL course. They will be expected to present evidence of their competence and ability in all facets of the design problem and its realisation, in the selection and use of materials, tools / equipment and techniques.

(iii) Origin of your idea - an explanation of the background to your design project including an account of how you came to develop it (perhaps a perceived gap in the market or user dissatisfaction with existing products).


(iv) User needs and market requirements - determine who/what is the target market and what are the general characteristics of that market and the needs you expect your product to meet. What advantages or disadvantages does your product have over existing products? How much do similar existing products cost?

(v) Technical and design factors - explain the technical feasibility of your design, pointing out areas of uncertainty and further information required.Will the idea work?

What will existing equipment/facilities allow?

Are the necessary materials and components available?What technical problems are there to be solved?Can the product, device or system be made easily?Are there any special production requirements?

(vi) Financial and economic factors – explanation of the economic viability of your product including preliminary costings - (price minus approach).

(vii) Social and environmental impact – what are the social and environmental issues raised by your product proposal for example the environmental impacts of manufacturing in quantity, the impact of the product in use, the product life cycle, disposal of the product at the end of its useful life.

(viii) Design insights – What are the lessons you have learned through undertaking this design task in terms of the process of invention, design and innovation. (This should be related to the specification content units).

(ix) Design Evaluation – The evaluation of the project may be defined as a study containing information related to the product's performance specification, the results of end testing and feedback comments provided by the target audience. This information may be word processed and included in the project report.

Centres are reminded that a discrete project report is not a requirement, but candidates may find it more convenient to separate this material from the design sheets. Also, careful consideration of Key Skills requirements whilst compiling this report should mean that it produces some of the evidence required for assessment of Key Skills in Communication and possibly IT.

Integration of specification content.

Selected content from the specification that allow opportunities for integrating Knowledge and Understanding into the main project are listed below. See also the integration of specification content into the extended task (page 8).
