Student-Teams Achievement Division, Mathematical Reasoning and Self-efficacy Beliefs

This dataset is from a research project aimed at investigating the effect of the Student-Teams Achievement Division on students' mathematical reasoning and self-efficacy beliefs. The data were collected from 301 secondary school students aged 14 to 20. The data include participants' demographics, independent variables, dependent variables, mediating variables, and the covariates as applicable to each of the associated prospective manuscripts. The dataset is accompanied by three supplementary files: The R script for a robust ANCOVA procedure, the PROCESS macros for SPSS output and the Multilevel modeling analysis SPSS output.本数据集源自一项旨在探究学生团队成就分组法（Student-Teams Achievement Division）对学生数学推理能力与自我效能感影响的研究项目。研究共采集了301名年龄介于14至20岁的中学生的相关数据。数据集涵盖参与者的人口统计学信息、自变量、因变量、中介变量，以及适配各篇关联待投稿件所需的协变量。本数据集附带三份补充文件：分别为稳健协方差分析（ANCOVA）流程的R脚本、用于SPSS输出的PROCESS宏程序，以及多层建模分析的SPSS输出文件。
