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:
- Survey market to collect information about different dyes, pigments available and compare them based on their properties, applications, and prices.
- Visit any natural fibre process house nearby and collect information from the processing in-charge about various processes conducted.
- Library/ internet survey of developments in dyes, pigments and their applications.
- Prepare shade card using combination of primary colours.
- Prepare presentation incorporating visuals, photographs, animations, video on process sequence of dyeing natural fibres.
- Collect information from the natural fibre process house about the faults in dyeing and relevant remedies.
- Collect information on safety precautions of various chemicals and machinery used in the process house.
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 tradinal 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/snb-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.
- Demonstrate students thoroughly before they start doing the practice.
- Encourage students to refer different websites to have deeper understanding of the subject.
- Assign unit wise assignments to group of 4 to 5 students for solving unit wise questions.
- Use of video, animation films to explain concepts, facts and applications related to dyeing of natural fibres.
