Education Quality and Teaching Practices
通过智利薄弱学校的随机对照试验，评估指导式教学法的效果，发现其显著提升学生成绩但对最贫困儿童效果有限，且未改善师生互动质量。
Abstract Improving school quality with limited resources is a key issue of policy. This article uses a randomised controlled trial (RCT) to estimate the effectiveness of guided instruction methods as implemented in under-performing schools in Chile. The intervention improved performance substantially, and equally for boys and girls. However, the effect is mainly accounted for by children from relatively higher-income backgrounds. Basing our study on the Classroom Assessment Scoring System (CLASS) instrument, we document that the quality of teacher–student interactions is positively correlated with the performance of low-income students; however, the intervention did not affect these interactions. Guided instruction improves outcomes, but the challenge to reach the most deprived children remains.
