Abstract:
The present paper shows how conceptual maps may be used as constructivist instruments in the process of teaching, learning and assessing of certain concepts from the atomic and nuclear Physics. Two conceptual maps are presented, one referring to X radiations and the other to the nuclear reactions. The first map connects the concepts specific to the study of X radiations, grouped in several graphic routes that comprise the properties and use of these radiations, their classification according to the generation mechanism and the experimental installation producing X radiations. The second map groups the concepts referring to the definition of nuclear reactions in several graphic routes, their classification according to several criteria and the application of the conservation laws in the study of the nuclear reactions. The two maps can be connected on the basis of common elements and any concept from either map may be used to develop new conceptual maps. In this way, the model Cognitive Information Processing (CIP) is sustained, ensuring that theoretical presentation is in the form of reorganization schemes for acquisitions from memory, which become the basis for the assimilation of new competences and formation of personal outlook regarding a domain of knowledge. The use of these instruments supports both the teacher in the teaching and assessing stages and the students in their effort to clarify and systematically methodize key concepts from chapters of Physics that synthesize a large part of the knowledge about the phenomena at atomic and nuclear scale.
