Effectiveness of a Conceptual Change-Oriented Teaching Strategy To Improve Students' Understanding of Galvanic Cells

摘要

Students and teachers in several countries find electrochemistry topics difficult to comprehend because of their abstract and dynamic nature(1-4).Intending to analyze this difficulty,researchers have conducted a number of studies to identify students' misconceptions(5-15).The results of these studies show that students from different countries and at different levels have common misconceptions in electrochemistry.Likewise,concepts are often poorly presented to students,who then typically just memorize the concepts without gaining a meaningful understanding.
