RESEARCH DATA: Formation of teacher expectations: Evidence from a factorial survey experiment manipulating student information

This dataset supports the analysis of a vignette experiment investigating teacher expectations of students (currently in review). It includes structured data and analysis scripts used to study how teachers form expectations based on manipulations of student engagement, characteristics of social group membership and instructional context. This repository includes an R script used for the analysis of the experimental data, along with an accompanying Excel codebook file detailing variable definitions and data structure. Both resources are designed to facilitate reproducibility and provide clear documentation of the study's methodology.

本数据集用于支持一项探究教师对学生期望的情境实验（vignette experiment）的分析工作，目前该研究稿件尚处于同行评审阶段。本数据集包含结构化数据与分析脚本，用以探究教师如何基于学生参与度的操控、社会群体归属特征以及教学情境来形成对学生的期望。本代码仓库包含用于分析该实验数据的R脚本，以及一份配套的Excel格式代码本（codebook），其中详细列明了变量定义与数据结构。上述两项资源均致力于提升研究的可复现性，并清晰呈现本研究的方法论细节。
