Microscopic approach to entropy through the ice melting example

Abstract

Aiming at the conceptual understanding of entropy and the concepts involved in it within a microscopic approach, a Teaching Learning Sequence was developed. Taking as a starting point the concepts taught and the models used in the previous units of TLS, the trainees, students of the Primary Education Department, were asked to justify the change of entropy in the ice melting process. Through analyzing and interpreting their discourse and proposed models, their evolving understanding of the concepts and the difficulties they encountered with these models were emerged. These data indicated changes introduced in the TLS designed after its pilot implementation.
