本手稿 (i) 介绍了化学概念清单 (CCI)，教师可以使用该清单自行判断学生中几种常见替代概念的程度； (ii) 证明学生在学习普通化学时具有化学和科学教育研究文献中描述的各种替代概念； (iii) 表明传统的普通化学课程只能在基本概念的理解方面产生适度的提高。不正确的概念包括关于原子和分子、微观行为、热和温度、化学式、气体和其他定性概念的不恰当想法，这些概念构成了大学化学第一学期几个主题的基础。该清单是一个多项选择工具，由基于科学教育文献中报告的替代概念的单层和两层非数学问题组成。科学与工程专业两学期普通化学课程第一学期前的清单管理证实，学生在课程开始前对化学的不同领域持有许多不同的概念。第二学期初的清单管理表明，这些学生在一个学期的教学中保留了许多替代概念。
This manuscript (i) presents the Chemical Concepts Inventory (CCI), an inventory that faculty can use to judge for themselves the extent of several common alternate conceptions among their students; (ii) demonstrates that students come to general chemistry with a variety of the alternate conceptions described in the chemical and science education research literature; and (iii) shows that a traditional general chemistry course results in only modest improvements in understanding of basic concepts. The incorrect concepts include inappropriate ideas about atoms and molecules, microscopic behavior, heat and temperature, chemical formulas, gases, and other qualitative concepts—concepts that form the foundation of several topics of first-semester college chemistry.The inventory is a multiple choice instrument composed of one- and two-tiered nonmathematical questions based on alternate conceptions reported in the science education literature. Administration of the inventory before the first semester of a two-semester general chemistry course for science and engineering majors confirmed that students hold many alternate conceptions in diverse areas of chemistry prior to the course. An administration of the inventory at the beginning of the second semester indicated that these students retained many of their alternate conceptions through a semester of instruction.
