Graphic organizer for constructivist approach of advanced science concepts: “Magnetorezistence”

摘要

Informational burst nowadays staying in unprecedented development of technical applications is a real challenge for science teachers wishing to offer to their younger and younger interested students the opportunity to reach advanced science concepts. It is very hard for national curriculum to cover all knowledge as to be up to date in a historical approach. Students are very interested in finding out all about the gadgets present everywhere but they don’t have the patience to wait till advanced concepts are taught. A solution may be a great change in teachers’ attitude about teaching as to keep students interested in science. Constructivist approach means elaborating graphic organizers as instruments intended for knowledge construction using primary restyling of information and mental images forming. We present a graphic organizer as a cognitive map/ scheme projected to cover the main targets used in a creative lesson, to encourage metacognition and collaborative relationships between students and between teacher and students.
