In a flipped classroom, an increasingly popular pedagogical model, students view a video lecture at home and work on exercises with the instructor during class time. Advocates of the flipped classroom claim the practice not only improves student achievement, but also ameliorates the achievement gap. We conduct a randomized controlled trial at West Point and find that the flipped classroom produced short term gains in Math and no effect in Economics. The flipped model broadened the achievement gap: effects are driven by white, male, and higher achieving students. We find no long-term average effects on student learning, but the widened achievement gap persists. Our findings demonstrate feasibility for the flipped classroom to induce short term gains in student learning; however, the exacerbation of the achievement gap, the effect fade-out, and the null effects in Economics suggest that educators should exercise caution when considering the model.

课堂教学翻转的影响：来自随机试验的证据

在翻转的教室（一种日益流行的教学模式）中，学生们在家观看视频讲座，并在上课期间与教练进行练习。翻转教室的拥护者声称这种做法不仅可以提高学生的成绩，而且可以改善成绩差距。我们在西点​​军校进行了一项随机对照试验，发现翻转的教室在数学上产生了短期收益，而对经济学没有影响。翻转的模型扩大了成绩差距​​：效果是由白人，男性和成绩较高的学生驱动的。我们发现对学生的学习没有长期的平均影响，但是成就差距的扩大仍然存在。我们的发现表明，翻转教室可以诱使学生短期学习；但是，成就差距的加剧，影响的淡出，
