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 (student’s) portfolio which will be useful for their placement interviews:
- Prepare report on market survey of various three phase transformers (specification, manufacturer, application, cost)
- Prepare model of single phase transformer.
- Prepare power point presentation related to D.C. Machines.
- Prepare power point presentation related to transformers.
- Prepare a chart of industrial application of D.C. Machines.
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.
- L’ 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/sub-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.
- Use Flash/Animations to explain various theorems in circuit analysis
- Guide students in undertaking micro-projects.
