The implementation of practical sessions in engineering education:

• Paves the way for students to be familiar with the instruments and thus, with the industrial real-world

• Augment the learning outcomes by strengthening the understanding of scientific concepts and theories

Page 3: UNED MURE Project Amman

Princess Sumaya University for Technology, Amman, Jordan, 14-15 November 2012

Unfortunately, there exist a wide gap between the engineering educational curricula and the industrial real-world owing to:

• The lack of experimentation availability• The high cost of equipment and administration burdens

Page 4: UNED MURE Project Amman

Princess Sumaya University for Technology, Amman, Jordan, 14-15 November 2012

• Online Laboratories address these needs providing on-line ubiquitous workbenches unconstrained by neither temporal nor geographical considerations

• Recently, hundreds of online laboratories have been developed at many universities

Design & Development

Page 15: UNED MURE Project Amman

Princess Sumaya University for Technology, Amman, Jordan, 14-15 November 2012

The common generic architecture design of today’s remote laboratory for industrial electronics applications

Page 16: UNED MURE Project Amman

Princess Sumaya University for Technology, Amman, Jordan, 14-15 November 2012

There exist three major challenges in building remote laboratories:• Selecting the lab server software• Selecting the client-server communication technology• Integrating the remote laboratories with the Learning Management System

Page 17: UNED MURE Project Amman

Princess Sumaya University for Technology, Amman, Jordan, 14-15 November 2012

The common outstanding technologies applied for remote laboratories lab server software development are LabVIEW and MATLAB

Page 18: UNED MURE Project Amman

Princess Sumaya University for Technology, Amman, Jordan, 14-15 November 2012

Both possess rich and powerful features:

• Data exchange with other GUI applications such as COM, ActiveX, CGI, Java and .Net applications, and web services

• Support for standard Application Programming Interfaces (APIs) such as IVI, VISA, PXI, GPIB, VXI, USB, LXI, and others

• Connection with ODBC or OLEDB compliance database; compilation as DLL files to be called from the Lab server software as a driver to execute the experiments on the hardware

• Support for OPC Servers to enable HMI and SCADA

Page 19: UNED MURE Project Amman

Princess Sumaya University for Technology, Amman, Jordan, 14-15 November 2012

• LabVIEW is the most popular remote laboratory environment and it is the most outstanding representative of graphical programming language visualization and parameter tuning for remote operation

• MATLAB is the most powerful computing language for control algorithm development and simulation

• Full using of their advantages can achieve high efficiency programming. In numerous remote laboratories applications, a hybrid method was adopted; the signal acquisition and the GUI were developed with LabVIEW, while numerical calculation and signal processing were developed with MATLAB

Page 20: UNED MURE Project Amman

Princess Sumaya University for Technology, Amman, Jordan, 14-15 November 2012

LabVIEW can support several ways of hybrid programming with MATLAB by means of:• ActiveX automation technology• DLL technology• COM technology• MathScript RT Module

Mathscript module allows embedding .m file scripts in LabVIEW applications by connecting the text-based I/O variables with the inputs and outputs of LabVIEW

Page 21: UNED MURE Project Amman

Princess Sumaya University for Technology, Amman, Jordan, 14-15 November 2012

The client-server layer is responsible for the communication between user interface and the lab server

Page 22: UNED MURE Project Amman

Princess Sumaya University for Technology, Amman, Jordan, 14-15 November 2012

• The client-server layer is responsible for the communication between user interface and the lab server

Page 23: UNED MURE Project Amman

Princess Sumaya University for Technology, Amman, Jordan, 14-15 November 2012

There exist a wide variety of technologies for the communication between client-server:

Desktop Sharing security problems

• Virtual Network Computing (VNC) very slow

• Remote Desktop Protocol (RDP) limited to a single connection Common Gateway Interface (CGI) performance problems ActiveX and Java Applets plugins required

Rich Internet Applications (RIAs) plugins required LabVIEW Web server only with LabVIEW applications

Asynchronous JavaScript and XML (AJAX) the actual trend

Each of these solutions have its relative advantages and disadvantages. However, the trend is more shifted towards web standards such as AJAX and Web services. On the mean time for LabVIEW applications LabVIEW web interface is the common choice

Integration & Implementation

Page 25: UNED MURE Project Amman

Princess Sumaya University for Technology, Amman, Jordan, 14-15 November 2012

Recently, remote laboratories have been developed at multiple universities and adopted in engineering education. Furthermore, some of these laboratories are replicated at many universities such as the electronic circuit’s remote labs: NetLab, VISIR, and labs based on NI ELVIS II

Page 26: UNED MURE Project Amman

Princess Sumaya University for Technology, Amman, Jordan, 14-15 November 2012

This was the commence of a new mainstream which advocates a better remodeling of those laboratories to allow their allocation, sharing among universities, and their communication with other heterogeneous systems, e.g., Learning Management Systems (LMS)

Page 27: UNED MURE Project Amman

Princess Sumaya University for Technology, Amman, Jordan, 14-15 November 2012

The integration of remote laboratories with educational platform could be classified as follows:

Integration with Learning Management Systems (LMSs) Integration with Metadata Repository Integration with Remote Laboratory Management Systems (RLMSs)

Page 28: UNED MURE Project Amman

Princess Sumaya University for Technology, Amman, Jordan, 14-15 November 2012

I. Integration with Learning Management Systems (LMSs)

LMS is a software application for the realizing classrooms and courses online

Page 29: UNED MURE Project Amman

Princess Sumaya University for Technology, Amman, Jordan, 14-15 November 2012

I. Integration with Learning Management Systems (LMSs)

LMSs have been widely used in distance education for the past two decades. It provides many tools and features such as: Administration Tools: user registration, account roles, user profile, assign

tutors, students and groups, billings, design course contents, scheduling, etc. Synchronous and Asynchronous Communication Tools: chat, forums,

video conference, webinars, events, news, emails, calendars, blogs etc. Multimedia sharing Tools: Upload and download videos, audios, photos, files,

etc. Evaluation and Tracking Tool:. Surveys, exams, assignments, user tracking, etc. Standard Compatibility: LMS organizes the content in a hierarchical structure

with regarding to a specific standard in order to allow swapping contents between different LMS without re-writing it again. From the most common used standards are: Shareable Courseware Object Reference Model (SCORM) & IMS for content

packing IMS QTI (Question and Test Interoperability) for tests and evaluations, Learning Object Metadata (LOM) and Dublin Core for describing and reusing

learning objects.

Page 30: UNED MURE Project Amman

Princess Sumaya University for Technology, Amman, Jordan, 14-15 November 2012

I. Integration with Learning Management Systems (LMSs)

LMS can be open source such as: Moodle , dotLRN, Sakai, Claroline, etc. which could be easily developed and redesigned, thus all our researches are realized focusing on these types of LMS. While Proprietary types such as Blackboard, JoomlaLMS, SharePointLMS, etc. could only be modified by their developers.

Page 31: UNED MURE Project Amman

I. Integration with Learning Management Systems (LMSs)

Even though, most of the features provided by LMS are of crucial importance to practical sessions. LMS, however, is confined to theoretical resources and doesn’t support their practical counterparts
