We present the “AggiornaMenti” project, a laboratory-based training course on physics for Italian junior high school teachers. Lessons are based on the Inquiry Based Science Education Method (IBSE), and teachers learn to perform simple experiments using materials that can be easily found at home. The topics are mechanics, fluids, electromagnetism, and thermodynamics. The impact of the course has been evaluated by a qualitative feedback questionnaire. Results show that our methodology was appreciated: the teachers implemented the “learning-by doing” approach at school and they also felt that students will have benefits even for their future.
