Research

Current Research

My Research at the department of psychology focuses on integrating computer adaptive testing into game-based online learning environments. One of the main projects I'm working on is the development of the Math garden (www.rekentuin.nl). The Math garden is a challenging web environment for children to practice arithmetic skills. It consists of a web-based computer-adaptive monitoring system, which tracks both accuracy and response time. Using a new model based on the Elo (1978) rating system and an explicit scoring rule, estimates of ability level and item difficulty are updated every trial. Items are sampled with a mean success probability of .75, making the tasks challenging yet not too difficult.
