Suggested Special Instructional Strategies:

Suggested Titles of 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:

Comparative study of various linear measuring Instruments Like Steel Rule, Inside -outside Calliper, Inside-outside Vernier caliper, Inside-outside Micrometer, Digital Vernier caliper. Digital Micrometer (any one) with proper justifications.
Comparative Study of surface finish of Various Samples manufactured by various manufacturing processes (min.5) using surface roughness instruments with proper justification
Collect information of Coordinate Measuring Machine and prepare a report.
Comparative study of different parameters of Spur gear (Min. 5) having same module using appropriate instruments.
