We evaluate the effects of an online self-assessment tool on teachers' competencies and beliefs about ICT in education. The causal impact of the tool is evaluated through a randomized encouragement design, involving 7,391 lower secondary teachers across 11 European countries. Short-run impact...

This paper provides experimental evidence for the impact of home internet access on a broad range of child outcomes in Peru. Children who were randomly chosen to receive laptops with high-speed internet access are compared with i) those who did not receive laptops and ii) those who only received...

Using Italian data on standardized test scores, we show that the substantial heterogeneity in how performance changes with the position of questions can alter the rank of individuals and classes as the length of the test increases. We examine whether decomposing test scores into initial...

Using a randomized field experiment in Costa Rica, we estimate the effect of providing parents of preschool students with a text message intervention containing information and activities to engage them with their children's learning process at home.

We evaluate two variants of a school-based, intensive learning camp for pupils who are assessed 'not ready' for further education after compulsory school, using a stratified cluster randomized trial involving 15,559 pupils in 264 schools in Denmark. Next to training pupils in Danish and...

This paper presents results from a randomized evaluation of a home visiting program for disadvantaged first-time mothers and their families implemented in Germany. 12 months after birth, the intervention increases infants' cognitive development by 0.18 SD. However, the effect fades out after 24...

We collected personality (Big Five) and demographic characteristics, and ran incentivized experiments measuring cognitive skills (non-verbal IQ, numeracy, backward induction/planning), and economic (time, risk) preferences, with 100 students at a small public undergraduate liberal arts college...

This paper presents results from a randomized evaluation of a home visiting program for disadvantaged first time mothers and their families implemented in three German federal states. At the end of the first year of the program, children in home visited families perform significantly better than...
