摘要：Constructivist paradigm is one of the most favorite theory nowadays when is needed to change the perception of science teaching. It is well known that advanced physics concepts used in everyday life may not be developed during science classes when students needs an explanation, so the teacher has to be creative and improve some useful tools destined to enlarge their perception. Graphic organizers offer a better hand of students’ access to met cognition and reflection and a panoramic view to the whole as to understand the details. Cognitive maps developed by the teacher according to students’ interests and level of understanding valorize their potential to search, to find suitable interpretations, to establish connections. Magnetoresistive materials are used widely so it is very useful to approach in a constructivist way. We present a complex cognitive map to be used and adapted for different levels of cognition in order to be a useful tool for teachers.
