Implementing challenging mathematics tasks with multilingual students who are not yet fluent in the instructional language is difficult for monolingual teachers because of the linguistic and cultural differences between the teacher and students. In this study, we examined how monolingual preservice teachers set up cognitively demanding mathematics…

Mathematical problem solving typically involves manipulating visual symbols (e.g., equations), and prior research suggests that those symbols serve as diagrammatic representations (e.g., Landy & Goldstone, 2010). The present work examines the ways that instructional design of student engagement with these diagrammatic representations may…
