“高职院校数学教师核心素养量表”的编制

Compilation of Core Competencies Scale for Community College Mathematics Teacher

在理论研究和专家访谈的基础上构建高职院校数学教师核心素养模型.通过维度设计、项目选编和评估编制"高职院校数学教师核心素养量表",进行整体层面和分层面的探索性因素分析,通过逐项删除不合理题项,从而确认量表的因素结构,建立量表的建构效度.进一步采用结构方程模型法对量表进行验证性因素分析,经由对初始模型的3次修正,最终得到一个二阶因素模型与实际数据相契合,因此说明量表具有建构效度.该模型的二阶因素为高职院校数学教师核心素养,3个一阶因素为知识、能力和品性,其中知识因素可以分为本体性知识和条件性知识两个观测变量,能力因素分为数学能力、数学教学能力和专业发展能力3个观测变量,品性因素则分为认识信念和态度两个观测变量.

The theoretical framework of core competencies model for community college mathematics teacher was research-informed which was based on both the mathematics education and vocational education.Moreover,the model was verified by means of expert interviews.Through a series of dimensional design,coding,item-selecting and evaluation,the core competencies scale for community college mathematics teacher was compilated.Exploratory factor analysis and confirmatory factor analysis were carried out to explore the construct validity.Results showed the scale high reliability and construct validity.The model was consistent with the theoretical framework and the data collected.It was a second-order factor model,summed up as core competencies,which had three factors-knowledges,skills and disposition.
