Unit 3 Problem Solving

About the Candidate

The candidate who produced this work is an ICT teacher who undertook this course as part of his

Continued Professional Development (CPD) and to pilot a Level 3 course for his centre.

About the Work

As the only candidate much of the course was ’self-taught’ and all templates used have been

developed by the candidate. This situation is obviously not the normal scenario in which this course

is delivered. The aim of the exemplar work is to provide colleagues with an example of work that will

hopefully prove useful when planning and delivering this unit of work.

Please note that this work has not been endorsed as exemplar work by OCR, and has been made

available as a form of guidance by a teacher for fellow teachers.

Overall this unit of work was graded Distinction.

Throughout the creation of the spreadsheet I have used consistent headings and titles both for the

spreadsheet and the analyse. This allows the data to be easily interpreted. The above also one part

of the analysis that will give guidance of the amount of data collect and its distribution.

The above shows the functions that have been used in this spreadsheet to analyse the data so that it

is useful when proving or disproving the hypothesis.

At the bottom of the spreadsheet I used the formula COUNTBLANK to count the numbers of blank

cells (if any) were in the spreadsheet. This would quickly show me if any data was missing.

To test the formulas I entered 14 pieces of data. This data included both male and female, a small

sample of each year and ability group and a range of preferred homework methods. The benefit of

using a small sample of data such as this is that it can easily be counted by hand to confirm that the

formulas are accurate.

I have used several worksheets to organise the spreadsheet


Testing the Data

To test the data I have added 14 random entries into the spreadsheet this will allow me to check

with a manageable number that the formulas work as indented.

Once entered I will count the individual data and then check that this correlates to the data that

appears in the analysis section of the spreadsheet.

In addition I have also created a tick list to check the functionality of the other elements of the

spreadsheet including the cell validation.

By creating and running a series of test it will ensure that any issues can be corrected before the

data is actually entered into the spreadsheet, along with helping to minimise any errors that could

skew the results.
