Science students are increasingly challenged to use technical language related to the topics that they are studying, and therefore, science teachers benefit from knowing which tools are effective to support students in learning to use new terms. This study examined the impact of using one such tool--sentences frames--to teach science vocabulary,…

Although extensive research has shown the educational value of different types of interactive visualizations on students' science learning in general, how such technologies can contribute to English learners' (ELs) understanding of complex scientific concepts has not been sufficiently explored to date. This mixed-methods study investigated how…

As part of a three-year curricular and professional development intervention focused on English language learners (ELLs), this study examined the intervention's effect on teachers' science knowledge and instructional practices after one year of implementation. The P-SELL (Promoting Science Among English Language Learners) intervention comprised…

Recent education reform efforts have included an increasing push for school science to better mirror authentic scientific endeavor, including a focus on science practices. However, despite expectations that all students engage in these language-rich practices, little prior research has focused on how such opportunities will be created for…

This study documents how an urban high school science teacher engaged her English Language Learners (ELLs) in the discourse-intensive science and engineering practices of (1) arguing from evidence and (2) obtaining, evaluating, and communicating information. The teacher taught an introductory integrated science course to classes with a large…
