• Motivation• Achievements of the Pilot Phase• Proposed Areas and Virtual Labs• Lessons learnt from the Pilot Phase• Methodology for the Main Phase• Virtual Labs at IIT Roorkee

Motivation

Physical Distances Limit Doing Experiments

Sharing of Costly

Equipment

Quality Labs

Today most equipment come with a computer interface for control and data storage.

It is possible to design experiments around some of these equipment which would enhance the learning of students.

Internet-based experimentation further permits use of resources – knowledge, software, and data available on the web

Objectives of the Pilot Phase

• To crystallize the concept of a Virtual Lab, whichwill essentially comprise of a user-friendlygraphical front-end, working in synchronizationwith a backend, possibly consisting of asimulation-engine running on a server or actualmeasurement data or a real experiment.

• To identify the suitable topics, where Virtual Labs will provide maximum benefit to the students using them.

• To develop approximately Ten Virtual Labs as a proof of concept

Achievements - Pilot Phase

• Twenty-three Virtual Labs have been developed, integrated and are ready for field trials

• All labs are integrated to the main Virtual Labs website: www.vlab.co.in

• All these Virtual Labs have Related Material / Manuals / Additional resources Step-by-step procedures Quiz to test the understanding

• Trial runs are underway• Feedback is being collected in order to refine the

Virtual Labs

Objectives of the Virtual Lab Project(Main DPR)

• To identify suitable topics where Virtual Labs will provide maximum benefit to a large number of students using them.

• To design these Virtual Lab which will essentially comprise of a user-friendly graphical front-end, working in synchronization with a backend, possibly consisting of a simulation-engine running on a server or actual measurement data or a remotely-triggered experiment.

• To develop approximately one hundred and fiftyVirtual Labs in various areas of Science and

Intended Users

• College Students who do not have access to expensive equipment/ lab-facilities.

• High-school students, whose imagination will be triggered, possibly motivating them to take up higher-studies.

• Researchers in different institutes who can collaborate and share expensive equipment and resources.

• Different engineering colleges, who can benefit from the content and related teaching resources.

Sciences

Implementation Methodology based on Learning from the Pilot Phase

• Mid-Term evaluations• Trial Runs

– Inter-institute Trial matrix– Trials in Local colleges

• Feedback– From expert committee members– From actual users

• Whitepaper• Working document

Mid-term evaluations

• The pilot phase had two Mid-term evaluations• Members of the Expert committee look at the

actual demonstrations and provide a feedback• The lab-proposals for the main DPR have been

in accordance with the evaluation criteria set by the mid-term evaluations and feedback.

Trial Runs• Many labs are undergoing field trials• Methodology

– Trials within the Institute– Inter-Institute Trial matrix– Trials in Local Colleges

• Each faculty developing a virtual lab will get the lab technically evaluated by an expert

• The feedback from field trials are being documented, analyzed and used for refining the experiments

• Workshops are being organized to educate local colleges and use them for trial runs
