This document discusses the use of electronic mini labs (EML) to improve laboratory education in electronics engineering. EML allows students to purchase inexpensive electronic component kits to build circuits hands-on in the classroom. Using EML gives students individual responsibility for their work while reducing strain on laboratory equipment. Case studies show how EML was used to build projects like an LED flasher and analog to digital converter. The conclusion is that EML is a cost-effective, interactive method that improves the teaching and learning process by giving students more practical exposure and developing their higher-order thinking skills.

Innovative improvements in electronic engineering laboratory education using eml
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. 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
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. 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. 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.
