学生遇到的问题与理解的抽象概念的化学键，在以前的研究中发现，概述。本文介绍了一种用于评估14-16岁儿童化学键概念的两级多项选择题诊断工具的研制。对119名化学专业学生进行了问卷调查，并对结果进行了分析。他们发现持有的共同的替代概念被列出并进行了讨论。结果发现，该工具提供了一个易于管理的工具，以易于获取的形式提供结果。
Problems students encounter with understanding the abstract concept of chemical bonding, as revealed in previous research, are outlined. The development of a two-tier multiple-choice diagnostic instrument for assessing alternative conceptions about chemical bonding held by 14-16 year-olds is described. The instrument was administered to 119 chemistry students and the results analysed. The common alternative conceptions they were found to hold are listed and discussed. It was found that this instrument provided an easy-to-administer tool, providing results in a readily accessible form.
