Scientific sensemaking is core to learning and doing science. Oral and written language, visual and numerical representations, physical models, and other forms of communication are vital to scientific sensemaking, yet research has not yet fully explored how science curricula can be customized to account for the unique communicative repertoires of individual learners within elementary science classes. This project will address this important gap in practice by developing a suite of tools that elementary teachers can use to customize existing open-source, standards-aligned science curricula, such that these curricula are better able to support students with a range of communicative strengths, including multilingualism.
