We report on the use of bilingual constructed response science assessments in the context of a research and development partnership with secondary school science teachers. Given the power that assessments have in today's education systems, our project provided a series of workshops for teachers where they explored students' emergent…

The case of two middle school science teachers engaged in a long-term professional learning project is used to complicate the story of teacher change and agency and the presumed relationships between teacher knowledge and practice. Becky and Kelly were highly participatory in all aspects of a multi-year professional learning project, yet, when…

The Next Generation Science Standards (NGSS) call for students to exhibit an in-depth understanding of scientific inquiry practices, including direct observation, creative design thinking, and argumentation based on evidential learning. To support academic equity for multilingual learners, these new expectations require reconceptualization of…

This descriptive study examined urban elementary school teachers' perceptions of their science content knowledge, science teaching practices, and support for language development of English language learners. Also examined were teachers' perceptions of organizational supports and barriers associated with teaching science to nonmainstream students.…

Students in a grade 2-3, two-way bilingual classroom increased their understanding of scientific practice through a model-based methodology for science instruction. Students collaborated with peers and teachers to create computer models, construct physical models, and talk about their models in the classroom. Aspects of second language usage in…

This study examined the impact of a professional development intervention aimed at helping elementary teachers incorporate elements of students' home language and culture into science instruction. The intervention consisted of instructional units and materials and teacher workshops. The research involved 43 third- and fourth-grade teachers at six…
