11. SUGGESTED SPECIAL INSTRUCTIONAL STRATEGIES (if any)

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
Guide student(s) in undertaking micro-projects
Some of the topics/sub-topics is relatively simple and very easy to the students for self-learning, but to be assessed using different assessment methods
With respect to section No.09, teachers need to ensure to create opportunities and provisions for co-curricular activities
Guide students for using latest Technical Magazine
Arrange visit to relevant industry
Show video lectures on Microcontroller Applications with help of internet
Programming practices on simulators (free downloadable)

12. 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 is 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, workshop-based, 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 is given here. This has to match the competency and the COs. Similar micro-projects could be added by the concerned course teacher.

MICRO PROJECT 1: Prepare following Items

Prepare Specification Table for AVR microcontroller family
Design a chart of ATMega32 Architecture
