A blended learning framework for delivary of Laboratory Course in Digital Circuits during COVID-19 pandemic

The paper proposes a framework to demonstrate the effectiveness through blended learning in Digital Circuits Course by redesigning the content delivery and mode of hands-on experimentation. The present situation of pandemic has created scope for experimenting with various modes of course redesign and delivery for effective teaching/ learning of the courses. A Digital Circuit course in third semester of Engineering discipline is redesigned w.r.t. video lectures, course content, number of experiments, mode of learning, mode of teaching, simulations, hands on experimentation and evaluation rubrics. A webpage was designed for students comprising of all the information needed to conduct the laboratory efficiently. The video lectures were prepared by the course instructors on the concepts and design aspects of all the experiments. The designed experiments were simulated and shown to the students for its appropriateness. The designed circuits were hard wired on the breadboard and the results were demonstrated through the recorded videos of the same. Lab was conducted in marathon from morning to evening with more focus on detailed resources shared and learnt by students before conduction in lab without compromising learning in hardware related labs. All these details helped the students to gather extra knowledge for effective implementation of designed circuits. The effectiveness of learning was measured through designed rubrics and graded accordingly. The students were exposed to another way of efficient learning i.e., blended mode.
