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 coilect/record physical evidences for their (students) portfolio which will be useful for their placement interviews:
- Prepare the survey report on the applications of different types of number system and code converters used in the design of digital system.
- Compare technical specifications and applications of various types of memory, PLDs, CPLDs and Prepare report.
- Test digital ICs using various testing equipment like digital IC tester, Digital multimeter etc.
- Give seminar on any course relevant topic.
- Conduct library / internet suivey regarding different data sheet and manuals.
- Prepare power point presentation on digital circuits and their applications.
- Undertake a market survey of different digital ICs required for different applications.
- Search for video / animations / power point presentation on internet for complex topic related to the course and make a presentation.
Suggested Special Instructional Strategies:
These are sample strategies, which the teacher can use to accelerate the attainment of the various learning 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 provisions for co-curricular activities. .
- Guide students in undertaking micro-projects.
- PPTs/Animations may be used to explain the construction and working of electronic circuits.
- Guide students for using data sheets / manuals.
