INNOVATIVE TEACHING PRACTICES

An increasingly complex world requires an increasingly expansive education. We at the Department of Electrical Engineering, attain this through sustained and enhanced technical curriculum and rich learning environment. Learning can never cease – especially for engineers, because the world around us is changing at a rapid pace. Engineering and technological development becomes more and more globalized. To address these challenging issues, and produce competent professionals, the department of Electrical Engineering aims to build SMART (Specific Measurable Attainable Realistic Time bound) engineers through various modes of learning for overall holistic development of students: The learning is provided in the form of following innovative teaching practices. Some examples under each category are listed below.

1.      Flip class

 4.      Course projects

  Subject- Project Management                                                                                  

  Faculty-Mrs. Poornima Rao.

  Method used- Mini Project is given to understand concepts like SWOT analysis, M&D Analysis, Cost Analysis and SCBA.

 

 Group consisting of eight students are formed and they selected any one topic mentioned below.

  1. AC voltage measurement simulation / hardware using ARDUINO. (2 Groups)
  2. Digital timer using microcontroller.
  3. AC current measurement using ARDUNIO
  4. Power bank generator for mobile charging.
  5. Controlling light and fan using TV remote control (2 groups)
  6. Portable air cooler –Table top type.

After completion of each project, students were made to write an Executive summary for their project wherein they have mentioned about the summary of SWOT Analysis, M&D Analysis, Cost Analysis and SCBA.

5.      Expert lectures. - Every semester subject teacher arranges one expert lecture by an industry person for their subjects.
