Batteries workshop: a proposal for an active methodology for teaching electrochemistry

Abstract

Teaching chemistry in high school is becoming increasingly challenging. Therefore, the development of active teaching methodologies proves to be a facilitating and effective alternative in improving teaching-learning processes. As a result, this experience report describes the application of learning moments in the workshop format, which was entitled “Battery Workshop” in order to implement a different approach from traditional classes for teaching electrochemistry. The workshop consisted of the development and application of two electrochemistry experiments using low cost materials and reagents which were used in the construction of two piles: the lemon pile and the ice-form pile. Based on the observations and results obtained from evaluative activities, a satisfactory effect was noticed in terms of learning the main concepts worked on regarding the content of electrochemistry. This factor was evidenced by the high qualitative performance observed during the process and the high percentage obtained by the students in the average of the applied evaluation.
