Teaching with experiment and practicals is great. Some tools I would like to use are, Everycircuit, Phy apps, paper electronics, app inventor, lego, snap circuits and quizzes. I found that there is BYJUs, Khan Academy, NPTEL, Course era, UDEMY and EDX which are beneficial to students! I feel that one must also couple it with values, morals, negotiation, decision making, problem solving and honor code.
