We analyze the effect of substituting a weekly mathematics lessons in primary school grades 1-3 with a lesson in mathematics based on chess instruction. We use data from the City of Aarhus in Denmark, combining test score data with a comprehensive data base from administrative register. We use a...

Many organizations use onboarding programs to assist newcomers with the transition process. Are brief social interactions during such programs sufficient to create lasting performance spillovers? Exploiting quasi-random assignment to groups of a two-day freshman orientation program for...

To study whether a soft commitment device can help students succeed, we conduct a randomized field experiment and follow a cohort of tertiary students over six years. Students can commit to following their recommended study program structure, and they receive reminders each semester. This easily...

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...

In the context of a voluntary remedial math course for university students, we conduct randomized field experiments to study whether social information can help counteract low participation rates. Incoming students receive postal invitation and reminder letters that inform them about past...

We present first experimental evidence that relative performance feedback improves both the speed and quality with which challenging long-term tasks are completed. Providing university students with ongoing relative feedback on accumulated course credits accelerates graduation by 0.12 SD, and...
