Unit 5

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:

1. Collect specifications of different illumination schemes used in various units and write a technical report.
2. Visit various units and take the help of unit in-charge to understand various illumination scheme.
3. Collect data of different illumination schemes used for residential, commercial industrial units and various places such as gardens, garages, substations etc.
4. Write all the safety precautions which are to be taken while working with different illumination schemes..
5. Collect data of Lightning schemes.
6. Study the IS codes implemented.

Suggested Special Instructional Strategies:

These are sample strategies, which the teacher can use to accelerate the attainment of the various outcomes in this course:

1. Massive open online courses (MOOCs) may be used to teach various topics/sub topics.
2. 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.
3. 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).
4. With respect to item No. 10, teachers need to ensure to create opportunities and provisions for co-curricular activities.
5. Guide students in undertaking micro-projects.
6. Correlate subtopics with illumination schemes.
