Note: This specification table provides general guidelines to assist student for their learning and to teachers to teach and assess students with respect to attainment of UOs. The actual distribution of marks at different taxonomy levels (o f R. U and A) in the question paper may vary from above table.

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. Prepare journals based on practical performed in workshop.
2. Measure yarn evenness for set of yarns.
3. Give seminar on any relevant topic.
4. Library and internet survey regarding roving ring frame parameters used for different materials.
5. Prepare power point presentation or animation for showing building mechanism.

Suggested Micro-Projects

Only one micro-project is planned to be undertaken by a student that needs to be assigned to him/her in the beginning of the semester. In the first four semesters, the micro-project are group-based. However, in the fifth and sixth semesters, it should be preferably be individually undertaken to build up the skill and confidence in every student to become problem solver so that s/he contributes to the projects of the industry. In special situations where groups have to be formed for micro-projects, the number of students in the group should not exceed three.

The micro-project could be industry application based, internet-based, workshopbased, laboratory-based or field-based. Each micro-project should encompass two or more COs which are in fact, an integration of PrOs, UOs and ADOs. Each student will have to maintain dated work diary consisting of individual contribution in the project work and give a seminar presentation of it before submission. The total duration of the micro-project should not be less than 16 (sixteen) student engagement hours during the course. The student ought to submit micro-project by the end of the semester to develop the industry oriented COs.

A suggestive list of micro-projects are given here. Similar micro-projects could be added by the concerned faculty:

1. Draw frame slivers: Each batch will collect different draw frame sliver and prepare a card sheet by rearranging sliver in increasing order of its hank. .
2. Cotton slivers: Each batch will collect Card sliver/combed sliver/draw frame and compare them with each other.
3. Rove package fault: Each batch will collect two defective rove packages and take photograph of various package defects and paste on card sheet with description of their causes and possible remedies.
4. Building mechanism: Each batch will collect photographs of different building mechanism and their parts, and paste on card sheet with their names.
5. Objectionable faults: Each batch will collect different yarn faults and categories according to classmate faults on black card board sheet with description of their causes and possible remedies.
6. Yarn package fault: Each batch will collect two defective yarn packages and take photograph of various package defects and paste on card sheet with description of their causes and possible remedies.
7. Yarn twist and strength: Each batch will collect ten yarn sample and paste on card sheet rearranging in increasing order of twist and strength level.
8. Yarn evenness: Each batch will collect different yarn and test its evenness on evenness tester and record its cv%
9. Waste in ring frame: Each batch will collect different types of waste and paste on card sheet with description of their type.
10. Advances in Yarn Manufacturing; Each batch will explore the internet and would make a report in advances in manufacturing of yarn (including advances in materials, processes, machines and yarn quality) in different parts of world.
