[PRECONC 1] From DC to AC circuits : building of teaching/learning experiments to help students overcoming preconceptions acting as obstacles on the path to learning
Our research works in didactics of applied sciences have led us to develop an original framework of what is a preconception and how to overcome it : the Overgeneralized Domain of Validity-based Framework. It has been successfully applied to BA2 electricity course in EPB (statistically significant improvement in learning) through exercise and lab sessions.
It also revealed that the transition from DC circuits to AC circuits is not that easy in terms of methodology to follow, mathematical tools to use, or physical interpretation to deal with.
A large amount of preconceptions coming from daily life, textbooks or previous teaching act as learning obstacles preventing a smooth transition.
The aim of this master thesis is to build teaching/learning experiments of various possible types (ex-/post-tests, examinations' analysis, focus groups, interviews, etc) to better understand the origins of those learning difficulties, to possibly enhance our framework and, obviously, to develop teaching strategies to help students overcoming preconceptions acting as obstacles on the path to learning.
