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:
- Prepare journals based on practical performed in laboratory.
- Follow the safety precautions.
- Use various tools for maintenance of plastic machines.
- Library/Internet survey of plastic machinaries.
- Prepare power point presentation or animation for understanding different maintenance techniquies.
- Visit to plastic industry to show preventive and breakdown maintenance activities.
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 seif-directed learning and assess the development of the LOs/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 maintenances techniquies.
- Guide students in undertaking micro-projects
