A growing body of research suggests that comprehension of expository texts presented digitally is a challenging endeavor, particularly for children. Many reading interventions, both from traditional classroom settings and computer-based contexts, have focused on much needed strategy instruction but have simultaneously neglected a focus on…

Understanding equivalence is fundamental to STEM disciplines, yet misunderstandings and misconceptions inhibit students from fully appreciating or leveraging the concept. Using the game-based algebraic notation system, From Here to There! (FH2T), students explore ideas of equivalence by dynamically transforming expressions or equations among…

Learning fractions is a critical step in children's mathematical development. However, many children struggle with learning fractions, especially fraction arithmetic. In this article, we propose a general framework for integrating understanding of individual fractions and fraction arithmetic, and we use the framework to generate interventions…
