Teachers often deliver the same lesson multiple times in one day. In contrast to year-to-year teaching experience, it is unclear how this teaching repetition affects student outcomes. We examine the effects of teaching repetition in a setting where students are randomly assigned to a university...

Recent studies emphasize the importance of socio-emotional skills for the success in school as well as for later economic outcomes. However, little is known how practices used by teachers everyday in classrooms impact socio-emotional skills. We show that modern practices such as working in small...

We randomly assign more than 6,000 students from 150 primary schools in Bangladesh to work on math assignments in one of three settings: individually, in groups with random schoolmates, or in groups with friends. The groups consist of four people and are balanced by average cognitive ability and...

Most studies find little to no effect of classroom computers on student achievement. We suggest that this null effect may combine positive effects of computer uses without equivalently effective alternative traditional teaching practices and negative effects of uses that substitute more...

Using a stochastic frontier approach this paper evaluates the effects of substantial changes in the teaching material on students learning efficiency. The results indicate that the main effects of the re-organization on the learning efficiency was a decreasing importance of students' attendance...
