Pior investigation indicates that instructional gaming can be an effective tool for enhancing both motivation and achievement in the learning of mathematics. This study explores the extent to which the effectiveness of instructional gaming in facilitating the learning of specific mathematical ideas can be increased by incorporating devices that channel learners’ attention upon those ideas. In particular, the effect of channeling attention by changing the method of scoring is explored.
