科学探究参与度对青少年科学学业成就与态度影响的实证研究——基于PISA2015新加坡数据的倾向性分析

An Empirical Research on the Effects of Scientific Inquiry Engagement on Achievement and Attitude of Adolescents——Propensity Score Analysis of PISA2015 Data of Singapore

利用PISA2015新加坡数据,运用分层加权的倾向性分析方法有效控制样本选择偏差,考察科学探究参与度对学生科学学业成就与科学态度的影响效应。研究发现,PISA数据中人口统计信息、社会经济地位、学校特点、科学学习投入、科学课堂体验等因素对被试在各探究参与度水平的倾向有较强的解释力。同时,匹配加权后的研究结果表明,科学探究参与度对学生科学学业成就与科学态度具有显著影响,并揭示了影响效应的复杂性。

Based on the PISA2015 data of Singapore, this paper evaluated the effects of scientific inquiry engagement on achievement and attitude. Sample selection bias was controlled by using propensity score analysis method perform- ing within the marginal mean weighting through stratification. The study found that factors as social economic status, school characteristics, scientific learning input, science classroom experiences and so on made a strong explanation in the tendency of the inquiry engagement. The significant effects were identified on both cognitive and attitudinal out- comes, but also revealed the complexity of the effects.
