• 中文摘要： The purpose of this study was to investigate the difficulties students have in learning electrochemistry. The answers on an open-ended test on electrochemistry obtained from 9th graders, 12th graders, and college chemistry major students were compared and analyzed. The results of frequency analyses of student misconceptions and data from interviews revealed that a larger percentage of college students had misconceptions about the function of electrolytes in an electrochemical cell than did 9th or 12th graders. This study indicates that advanced study in chemistry does not always result in better understanding of certain basic concepts. More importantly, if the concepts are not clearly explained, students’ misconceptions may become firm and remain during their continued study of chemistry even at the college level. It is also found that the students’ misconceptions likely result from wrong impression given by pictures and statements in textbooks and improper classroom instructions.
