Adaptive practice and monitoring systems for education and research

In order to collect daily data on children’s cognitive development we developed a web-based practice and monitoring system for math and language based on an innovative application of computerised adaptive testing. These systems, Math Garden and Language Sea, are now used by over 200.000 children in the Netherlands. In this talk I will explain the algorithm behind the adaptivity of the system. The game based nature and especially the adaptively are attractive to children. Teachers are provided with detailed learning analytics. The data, over 600 million responses to items of 40 different tasks, are used for scientific research. I will give an overview of the studies we published in the last three years.
