The Pedagogy of Science and Environment: Experimental Evidence from Peru
在秘鲁公立小学用乐高套件替代传统教师中心教学，发现学生标准化测试成绩显著提高0.18个标准差，效果主要集中于基线成绩中位数以上的男生。
In today's knowledge-based societies, understanding basic scientific concepts and the capacity to structure and solve scientific questions is more critical than ever. Accordingly, in this article we test an innovative methodology for teaching science and environment in public primary schools where traditional (teacher-centred) teaching was replaced with student-centred activities using LEGO kits. We document positive and significant improvements of 0.18 standard deviations in standardised test scores. Such positive results are mainly concentrated within boys that were located above the median of baseline academic performance.
