Abstract:

This paper investigates how the spatial layout of a peer network affects academic performance using a field experiment conducted in a Chinese high school. In each classroom, students are sorted into study groups with balanced academic and gender compositions in the beginning of a semester. Each group contains six students sitting in two rows of three. In the treated groups, the top two students ranked by previous test scores are assigned to sit in the middle of each row. We find that the treatment effect is heterogeneous. It benefits the bottom two students but harms the middle two students. The negative effect to the two middle-score students, however, disappears when they are sitting on the same side. Our results suggest that the spatial layout of a group can have a significant impact on learning outcomes.
