This study examined elementary teachers' instructional strategies for promoting scientific understanding and inquiry and supporting English language development with diverse student groups including English language learners. The study was part of a 5-year research and development project consisting of reform-based science curriculum units and…

The study examined relationships among key domains of science instruction with English language learning (ELL) students based on teachers' perceptions of their classroom practices (i.e., what they think they do) and actual classroom practices (i.e., what they are observed doing). The four domains under investigation included: (1) teachers'…

As part of our professional development intervention, this study examined third-grade ELL students' writing achievement that included "form" (i.e., conventions, organization, and style/voice) and "content" (i.e., specific knowledge and understanding of science) in expository science writing. The study included six treatment schools from a large…

This study examined the effect of fidelity of implementation (FOI) on the science achievement gains of third grade students broadly and students with limited literacy in English specifically. The study was conducted in the context of a professional development intervention with elementary school teachers to promote science achievement of ELL…

Background: Current classroom practices have largely been shaped by changing student demographics, including English language learners (ELLs), and evolving accountability policies. The teacher professional development intervention in this study takes place against this backdrop. Research Questions: This study examined change in teachers' knowledge…

We describe a model professional development intervention currently being implemented to support 3rd- through 5th-grade teachers' science instruction in 9 urban elementary schools with high numbers of English language learners. The intervention consists of curriculum materials for students and teachers, as well as teacher workshops throughout the…

Student initiatives play an important role in inquiry-based science with all students, including English language learning (ELL) students. This study examined initiatives that elementary students made as they participated in an intervention to promote science learning and English language development over a three-year period. In addition, the…

This study is part of a 5-year professional development intervention aimed at improving science and literacy achievement of English language learners (or ELL students) in urban elementary schools within an environment increasingly driven by high-stakes testing and accountability. Specifically, the study examined science achievement at the end of…

This study examined the impact of the 3-year implementation of a professional development intervention on science achievement of culturally and linguistically diverse elementary students. Teachers were provided with instructional units and workshops that were designed to improve teaching practices and foster positive beliefs about science and…

As part of a larger project aimed at promoting science and literacy for culturally and linguistically diverse elementary students, this study has two objectives: (a) to describe teachers' initial beliefs and practices about inquiry-based science and (b) to examine the impact of the professional development intervention (primarily through…
