Scalebridge: Design and Evaluation of Adaptive Difficulty Proportional Reasoning Game for Children
Liudmila Tahai, James R. Wallace, Christian Eckhardt, Krzysztof Pietroszek · 2019
We present the design and evaluation of Scalebridge, an educational game that teaches children the mathematical skill of proportional reasoning. We also propose an adaptive level difficulty model that uses low-cost brain-computer interface device to modulate difficulty of the game based on the player's focus. We show that the game achieves the educational learning outcome of developing proportional reasoning skill both in the adaptive and in the non-adaptive version of game.
