For a few decades, policy makers, curriculum designers, and educators in several of the nations that have repeatedly ranked as top performers in mathematics have prioritized the introduction and featuring of these diagrammatic classroom practices. As incorporation of these diagrammatic practices has increased, so has the need to provide stakeholders with additional information about the effective and ineffective handling of diagrams in the classroom. In response to this need, I conducted a review of the empirical literature surrounding these diagrammatic practices. A total of 16 studies across 15 research articles met the literature search criteria. Major findings are as follows:
