摘 要:高中生对化学平衡的理解是重要且仍待深入探索的研究问题。潜在变量模型和数据挖掘有助于研究者从新角度了解学生的化学平衡概念学习情况。本研究使用自编的化学平衡命题测验,应用潜在类别分析和Apriori算法呈现722名高二年级学生对化学平衡命题的掌握情况。研究发现:(1)学生适合被分为3个组别,分别为高掌握水平组、中掌握水平组和低掌握水平组;(2)根据本研究设定的参数条件,未在高掌握水平组学生的作答中获得关联规则,在中掌握水平组和低掌握水平组学生的作答中获得了一些关联规则。潜在类别分析和Apriori算法可被用于化学概念学习和其他主题的研究。How high school students understand chemical equilibrium is an important research issue that still has to be deeply explored.Latent variable modeling and data mining are beneficial for researchers to understand students’concept learning of chemical equilibrium from a new perspective.With the self-made chemical equilibrium proposition test,this study utilized the latent class analysis and Apriori algorithm to represent 722 grade eleventh students’mastery of the propositions regarding chemical equilibrium.The findings showed that students were appropriate to be divided into three groups,which groups were named high level of mastery group,intermediate level of mastery group,and low level of mastery group.Based on the conditions of parameters set in this study,no association rule was found in the responses of the high level of mastery group but a few association rules were found in those of the other two groups.Latent class analysis and Apriori algorithm can be utilized to study the learning of chemistry concepts and other issues.
