Suggested Student Activities:
Other than the classroom and laboratory learning, following are the suggested student-related co-curricutar activities which can be undertaken to accelerate the attainment of the various outcomes in this course:
- Collect information on advances in plastics packaging and sealing.
- Collect samples of plastics pouches and different containers.
- Collect IS standards for Plastics used in food packaging.
- Prepare list of flexible packaging with examples.
- Prepare list of rigid packaging with examples.
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 topics in packaging technology.
- Guide students in undertaking micro-projects
