Learning Job Skills from Colleagues at Work: Evidence from a Field Experiment Using Teacher Performance Data
通过配对高技能和低技能教师共同工作，研究同事间技能学习对教师绩效的影响，发现低技能教师的学生成绩提高了0.12个标准差。
We study a program designed to encourage learning from coworkers among school teachers. In an experiment, we document gains in job performance when high- and low-skilled teachers are paired and asked to work together on improving their skills. Pairs are matched on specific skills measured in prior evaluations. Each pair includes a target teacher who scores low in one or more of 19 skills and a partner who scores high in (many of) the target’s deficient skills. Student achievement improved 0.12 standard deviations in low-skilled teachers’ classrooms. Improvements are likely the result of target teachers learning skills from their partner.
