化学职前教师手持技术TPACK调查研究

Survey of Pre-Service Chemistry Teachers’TPACK of Handheld Technology

设计了《化学职前教师手持技术TPACK量表式问卷》,对223名化学职前教师进行问卷调查,采取探索性因子分析与验证性因子分析检验问卷的信度、效度以及七因子模型的合理性,同时通过结构方程模型构建并讨论化学职前教师手持技术TPACK的发展路径。研究结果表明:(1)问卷具有良好的信效度;(2)TPACK七因子模型具有一定的合理性;(3)化学职前教师手持技术TPACK的发展路径中除CK对PCK无直接影响外,均支持TPACK的变革观点。文末据此对手持技术TPACK基础研究与化学教师发展两方面提出相应的建议。

In this study,223 pre-service chemistry teachers were investigated by designing the TPACK Scale Questionnaire for Pre-service Chemistry Teachers.Exploratory factor analysis and confirmatory factor analysis were used to test the reliability and validity of the questionnaire and the rationality of the seven-factor model.Meanwhile,structural equation model was used to construct and discuss the development path of TPACK for pre-service chemistry teachers.The results show that:(1)The questionnaire has good reliability and validity;(2)TPACK seven-factor model has a certain rationality;(3)In the development path of hand-held technology TPACK for pre-service chemistry teachers,except that CK has no direct influence on PCK,all of them support the reform view of TPACK.At the end of this paper,some suggestions were put forward for the basic research of TPACK and the development of chemistry teachers.
