Modeling Speed-Accuracy Tradeoff in Adaptive System for Practicing Estimation
Nižnan, Juraj
International Educational Data Mining Society, Paper presented at the International Conference on Educational Data Mining (EDM) (8th, Madrid, Spain, Jun 26-29, 2015)
Estimation is useful in situations where an exact answer is not as important as a quick answer that is good enough. A web-based adaptive system for practicing estimates is currently being developed. We propose a simple model for estimating student's latent skill of estimation. This model combines a continuous measure of correctness and response times. The advantage of the model is its simple update method which makes it directly applicable in the developed adaptive system. [For complete proceedings, see ED560503.]
