Suggested Student Activities:
Other than the classroom and laboratory learning, following are the suggested student-related co-curricular activities which can be undertaken to accelerate the attainment of the various outcomes in this course: Students should conduct following activities in group and prepare reports of about 5 pages for each activity, also collect/record physical evidences for their (students) portfolio which will be useful for their placement interviews:
- Collect from market the catalogues of electrical engineering materials such as
- Collect from internet or otherwise information on the different electromagnetic materials along with the forms in which they are available.
- Trace the connection diagram of control circuit of any equipment in the electrical laboratory.
- Make the list of manufacturers of wiring components and accessories.
- Make the list of manufacturers and suppliers of light fittings.
- Collect lhe information of substation earthing.
Suggested Special Instructional Strategies:
These are sample strategies, which the teacher can use to accelerate the attainment of the various outcomes in this course:
- Massive open online courses (MOOCs) may be used to teach various topics/sub topics.
- * in item No. 4 does not mean only the traditional lecture method, but different types of teaching methods and media that are to be employed to develop the outcomes.
- About 15-20% of the topics/suh-topics which is relatively simpler or descriptive in nature is to be given to the students for self-directed learning and assess the development of the COs through classroom presentations (see implementation guideline for details).
- With respect to item No. 10, teachers need to ensure to create opportunities and provisions for co-curricular activities.
- Guide students in undertaking micro-projects.
- Show video demonstration on safety precautions while working in electrical environment.
- Demonstrate the actions and care to be taken in case of electrical accidents.
- Arrange a visit to appliances/wire manufacturing unit / transformer or coil manufacturing unit/electrical shops / workshops.
- Arrange expert lecture of industry person in the area of electrical safety.
