本文介绍了17项数学研究生导师观察协议(GSIOP)在两所大学的发展和验证。该工具的发展出席了一些独特的需求,新手本科数学教师,同时建立在现有的工具,专注于课堂互动,特别是相关的学生的发展概念的理解,称为数学课堂观察协议的做法(MCOP 2)。工具验证包括两所大学的数学教育研究者和高级数学研究生导师的内容输入,内部一致性分析,评分者间信度分析,以及通过scree plot分析和探索性因素分析进行的结构分析。Cronbach-Alpha水平为0.868,说明内部一致性的可行水平。交叉表和相关性表明,除一个项目外,所有项目的评分者间可靠性都很高,所有子项目的评分者间可靠性都很高。协作scree图与探索性因素分析说明了三个关键分组与MCOP 2(学生参与和教师促进)的因素一致,同时添加了第三个因素,课程设计实践。总的来说,这些结果表明,GSIOP措施在本科数学课堂教师和学生的行动与美国数学协会(MAA)建议的做法,使用教师促进,学生参与和设计实践的三因素结构的程度。
This paper presents the development and validation of the 17-item mathematics Graduate Student Instructor Observation Protocol (GSIOP) at two universities. The development of this instrument attended to some unique needs of novice undergraduate mathematics instructors while building on an existing instrument that focused on classroom interactions particularly relevant for students’ development of conceptual understanding, called the Mathematical Classroom Observation Protocol for Practices (MCOP2). Instrument validation involved content input from mathematics education researchers and upper-level mathematics graduate student instructors at two universities, internal consistency analysis, interrater reliability analysis, and structure analyses via scree plot analysis and exploratory factor analysis. A Cronbach-Alpha level of 0.868 illustrated a viable level for internal consistency. Crosstabulation and correlations illustrate high level of interrater reliability for all but one item, and high levels across all subsections. Collaborating a scree plot with the exploratory factor analysis illustrated three critical groupings aligning with the factors from the MCOP2(student engagement and teacher facilitation) while adding a third factor, lesson design practices. Taken collectively, these results indicate that the GSIOP measures the degree to which instructors’ and students’ actions in undergraduate mathematics classrooms align with practices recommended by the Mathematical Association of America (MAA) using a three-factor structure of teacher facilitation, student engagement, and design practices.
