Innovative improvements in electronic engineering laboratory education using eml

Published on

This presentation discusses the innovative method of
laboratory learning in Electronic engineering at Government
Polytechnic Nagpur and Government Polytechnic Gondia.
Students were motivated to purchase their own electronic Mini-
Lab (EML) components. They designed simple yet fascinating
projects using EML. Students did all the development activities
individually. They helped each other and demonstrated
collectively. In the process, they learned many aspects of
engineering. This will make them skilled engineers. This provides
tremendous benefits in teaching learning process. It also boosted
the interest, confidence of students. Incorporating active/
cooperative learning into traditional instruction can be a useful
pedagogical tool to help students to perform practical and project
work. This concept is remarkably simple and cost effective but
extremely beneficial to teaching learning process.

Transcript of "Innovative improvements in electronic engineering laboratory education using eml"

  1. 1. Innovative Improvements in Electronic Engineering Laboratory Education using Electronic Mini Lab (EML): A Case Study Mr. V. J. Dongre Lecturer Electronics Govt. Polytechnic, Gondia (Maharashtra)
  2. 2. Importance of Laboratory Work in Engg. Cognitive Domain: Instrumentation, Experimentation, Mod eling, Data Analysis and Design. Psychomotor Domain: manipulating the apparatus, Sensory Awareness, Troubleshooting Skills. Affective Domain: behavior and attitudes learnt from failure, creativity, Curiosity, communicat ion, teamwork, safety, and ethics in
  3. 3. Size of Electronic components
  4. 4. Glimpse of Electronic Components
  5. 5. Characteristics of Electronic Labs • Instruments & components are small, delegate, fragile. • They need careful handling. • Quality of practical kits imposes problems. • Prone to wear and tear due to rough handling. • Malfunctioning of Kits due to Voltages of incorrect ranges or making wrong connections. • Difficult to experiment in big group of students.

  13. 13. Features and advantages of EML 1. They visit the market. It increases exposure. 2. Students purchase their own EML. This builds sense of belonging. 3. They handle their own components with care to avoid damage. 4. They work individually. So They are responsible for their success. Hence they are more attentive and focused. 5. Practical completes in short time. More time is available for doubt solving and assessment. 6. Students cooperate with each other to diagnose faults. This increases cooperation amongst the students. 7. As the students get 100% practical exposure, they also develop interest in theory classes. This synergies the teaching learning process. 8. Burden on College Lab is reduced as this activity is done in classroom.

  16. 16. Conclusion • EML is interactive and improved method of teaching learning. • Cost effective and portable. • Students are very enthusiastic in working with EML. • Students inculcate Higher order thinking for analysis, synthesis and evaluation. • The concept can be equally extended with suitable modifications in other branches of engineering. • EML along with modern technology resources like mobile camera and internet can serve as boon to practical teaching learning process.
