The Next Generation Science Standards (NGSS) offer a vision of science teaching and learning that presents both learning opportunities and demands for all students, particularly student groups that have traditionally been underserved in science classrooms. The NGSS have addressed issues of diversity and equity from their inception, and the NGSS…

Two leading science educators provide a comprehensive, state-of-the-field analysis of current trends in the research, policy, and practice of science education. This book offers valuable insights into why gaps in science achievement among racial, ethnic, cultural, linguistic, and socioeconomic groups persist, and points toward practical means of…

This study examined both student and school predictors of science achievement as measured by a high-stakes state test. The study involved 23,854 fifth-grade students from 198 elementary schools in a large urban school district with a diverse student population. Multilevel modeling was conducted to examine both student and school predictors…

The National Research Council (2011) released "A Framework for K-12 Science Education" that is guiding the development of the Next Generation Science Standards, which are expected to be finalized in early 2013. This article addresses language demands and opportunities that are embedded in the science and engineering practices delineated in the…

Teacher knowledge of science content is an important but under-studied construct. A curricular and professional development intervention consisting of a fifth grade science curriculum, teacher workshops, and school site support was studied to determine its effect on teachers' science content knowledge as measured by a science knowledge test,…

Grounded in teacher professional development addressing the intersection of student diversity and content area instruction, this study examined school teachers' pedagogical reasoning complexity as they reflected on their second language learners' science problem solving abilities using both home and school contexts. Teachers responded to interview…

Background/Context: With the ever increasing diversity of schools, and the persistent need to develop teaching strategies for the students who attend today's urban schools, hip-hop culture has been proposed to be a means through which urban youth can find success in school. As a result, studies of the role of hip-hop in urban education have grown…

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…

Background: In exploring how emergent bilingual learners' prior knowledge from home and play contexts might influence their scientific reasoning, this study drew upon two distinct research traditions: (a) experimental research from the developmental and cognitive psychology tradition, and (b) research on culturally and linguistically diverse…

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…

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'…

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…

Recent test-based accountability policy in the U.S. has involved annually assessing all students in core subjects and holding schools accountable for adequate progress of all students by implementing sanctions when adequate progress is not met. Despite its potential benefits, basing educational policy on assessments developed for a student…

The assessment of differential item functioning (DIF) in polytomous items addresses between-group differences in measurement properties at the item level, but typically does not inform which score levels may be involved in the DIF effect. The framework of differential step functioning (DSF) addresses this issue by examining between-group…

We address issues of science curriculum for nonmainstream students--students of color, students learning English as a new language, and students from low-income families--who are often concentrated in urban schools. First, we describe a theoretical framework for equitable learning opportunities with nonmainstream students. Building on this…
