This paper presents an innovative interactive scenario framework called ISLEC for the learning of electrical circuits by high school students or beginners of higher education. This framework aims to develop investigative, critical, creative, and decision-making skills by trainees, as well as aiming to tackle and resolve misunderstandings and learning difficulties. During each section of ISLEC, the student teams, through inquiry-based simulations, discover electrical principles by comparing a known to an unknown electric circuit for similarities and differences and make and verify predictions. Making use of the inductive reasoning, they come to conclusions and generalizations. The ISLEC was evaluated by students of civil engineering of the School of Pedagogical and Technological Education of Athens and, except other things, it considered by them as useful and usable.
