Direct linkJi-Eun Lee; Caroline Byrd Hornburg; Jenny Yun-Chen Chan; Erin Ottmar – Grantee Submission, 2022
This study investigated the effects of (1) proximal grouping of numbers; (2) problem-solving goals to make 100; and (3) prior knowledge on students' initial solution strategies in an interactive online mathematics game. In this game, students transformed an initial expression into a perceptually different but mathematically equivalent goal state.…

The Characterization and Evolution of Strategies about Vector Equations in the Game "Vector Unknown"
Mauntel, Matthew; Levine, Benjamin; Plaxco, David; Zandieh, Michelle – Digital Experiences in Mathematics Education, 2021
We present results of a grounded analysis of individual interviews in which students play Vector Unknown -- a digital game designed to introduce visualizing vectors, scaling vectors, vector addition, and vector equations, attending to the geometric and algebraic representations of vectors. The game was designed to be used at the beginning of a…
