摘要

本研究主要考察高中生对电化学概念的理解和遇到的困难,并比较土耳其和印度尼西亚高中生的思维模式。电化学概念问卷(ECQ)适用于 516 名印度尼西亚高中生和 516 名土耳其高中生。ECQ 包含 18 道选择题,这些问题分属五个不同的类别:电解过程中发生的反应、电解池和伏打池的区别、伏打池中离子的移动、伏打池中的极点和伏打池反应。研究结束时发现,印尼和土耳其高中生对电化学概念的理解相对薄弱,他们在电化学概念方面存在共同的困难。虽然两国学生在测试中的平均分没有显著差异,但根据试题确定,他们之间存在一些显著差异。得出的结论是,两国学生的其他概念与以往研究中确定的概念相似,如 "在电解过程中,电流产生离子 "和 "电子通过溶液从一个电极迁移到另一个电极"。在研究结束时,讨论了两国学生在理解电学概念方面出现相似结果和明显不同结果的原因。

Exploring senior high-school students’ understanding of electrochemical concepts: patterns of thinking across Turkish and Indonesian contexts

This study focuses on examining senior high-school students’ conceptual understanding and difficulties concerning electrochemistry and comparing patterns of thinking across Turkish and Indonesian contexts. The Electrochemistry Concept Questionnaire (ECQ) was applied to 516 Indonesian and 516 Turkish high school students right after the teaching of the electrochemistry topics. The ECQ contains 18 multiple-choice questions and these questions belong to five different categories: reactions occurring during electrolysis, differences between electrolytic and voltaic cells, movement of ions in voltaic cells, poles in voltaic cells, and voltaic cell reactions. At the end of the study, it was determined that both Indonesian and Turkish senior high-school students’ understanding of electrochemistry concepts was relatively weak and they shared common difficulties concerning electrochemical concepts. While there was no significant difference between the average scores of the students from both countries on the test, it was determined that there were some significant differences on the basis of questions. It has been concluded that students from both countries have alternative conceptions similar to those determined in previous studies such as “during electrolysis, the electric current produces ions” and “electrons migrate through the solution from one electrode to the other”. At the end of the study, the reasons for the similar results and the significantly different results for the students of the two countries to comprehend electro-concepts were discussed.
