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...

Many studies examine the importance of teachers in students' learning, but few exist on the contribution of principals. We measure the effect of principals on gains in primary test scores in North Carolina and estimate the standard deviation of principals' value added to be 0.12 -0.17. We find...

We evaluate a program that aims to improve children's reading skills by providing classes with age-appropriate reading material and incentivizing children to read through a 31 day read-a-thon. During the read-a-thon, the program significantly increases the propensity of children to read, causing...

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...

Behavioural attitudes towards risk and time, as well as behavioural biases such as present bias, are thought to be important drivers of unhealthy lifestyle choices. This paper makes the first attempt to explore the possibility of training the mind to alter these attitudes and biases, and...

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...

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...

Using the 3-year sample of the American Community Survey (ACS) for 2009 to 2011, we compute public school teacher salaries for comparison across U.S. states. Teacher salaries are adjusted for state differences in teacher characteristics, cost of living, household amenity attractiveness and...

Beyond some contracted minimum, salaried workers' hours are largely chosen at the worker's discretion and should respond to the strength of contract incentives. Accordingly, we consider the response of teacher hours to accountability and school choice laws introduced in U.S. public schools over...

How do teacher incentives affect student achievement? We contribute to this question by examining the effects of the recent introduction of teacher performance-related pay and tournaments in Portugal's public schools. Specifically, we draw on matched student-school panel data covering the...
