利用四段式测试题诊断高一学生化学键迷思概念

Using Four-Tier Chemical Bond Test to Diagnose Misconceptions of Senior High School Students

使用改编自迈阿密大学牛津分校Stacey Iowery Bretz的“化学键概念表征量表”,并通过加设信心指数将其扩充为四段式测试题.利用本测试工具对浙江省2所普通高中共260名学生进行测试.结果显示,被试存在“高信心指数错解”和“低信心指数正解”的情况,并探查出7个典型的化学键迷思概念,其中4个为呈现出较高信心指数的真性迷思概念.信心指数在一定程度上弥补了二段式工具的缺陷.

This study adopted a modified version of the Bonding Representation Inventory, which was developed by Stacey Lowery Bretz from Miami University Oxford, and improved it to four-tier test by adding the confidence rating tiers. The instrument was implemented on 260 grade one students from senior high school of Ningbo city. The findings indicated that most of the par- ticipants showed low confidence whereas their choices were correct, or high confidence whereas their choices were wrong. Seven significant misconceptions were identified and four of them were genuine ones with high confidence. The confidence rating used in this study improved the two-tier test to some extent.
