In this study, we present a conceptual tool for guiding teachers' principled pedagogical actions toward equitable instruction, referred to as the "Transforming Science Learning" (TSL) framework. The TSL framework was developed to address the challenges of enacting an ideological commitment in local contexts--promoting equity and justice…

Recent national reforms focus on learning disciplinary core ideas through engaging in science and engineering practices. These reforms also call for students and teachers to use crosscutting concepts (CCCs), or analytical lenses, that support scientific sensemaking and connections across disciplines. The "Framework for K-12 Science…

A growing body of work regarding teacher learning and implementation of reform has pointed to the significant role organizational contexts play in shaping teachers' engagement with reform and their implementation decisions. Within science education, the adoption of the Next Generation Science Standards (NGSS) and standards reflective of the…

The Next Generation Science Standards (NGSS) emphasize engaging students in science practices through which students can develop content, procedural, and epistemic knowledge of science. To accomplish this goal, science teachers must embed science content in authentic science practice. Successfully integrating content and practice will require…

In "A Framework for K-12 Science Education," researchers call for teachers to make dramatic shifts in practice -- and sustain in these changes in practice -- so students can engage in rigorous and equitable three-dimensional science learning. Project-Based Learning (PBL) motivates students from diverse backgrounds to persist in learning.…

The vision of the Framework and NGSS requires important shifts in teaching approaches and instructional materials. We argue that this commitment to engaging learners in meaningful practice and supporting students' epistemic agency entails that we support "coherence from the students' perspective." This coherence arises when students see…

This qualitative case study of 20 teachers enrolled in a two-year fellowship, examines the professional development of science teachers during participation in a professional learning community. Our professional development model specifically employs vertical teaming of teachers from elementary, middle, and high school levels to examine the…

This longitudinal study examined the extent to which teachers' participation in a 3-year professional development program enhanced their self-efficacy and prompted changes in science instruction in the early elementary grades. The study used a mixed-methods design, and included 39 teachers who taught in kindergarten, first grade, or second…

English learners are faced with the dual challenge of acquiring English while learning academic content through the medium of the new language (Lee et al. in "J Res Sci Teach" 45(6):726-747, 2008; Stoddart et al. in "J Res Sci Teach" 39(8):664-687, 2002) and therefore need specific accommodations to achieve in both English and the content areas.…

This study investigated the extent to which teacher professional development led to changes in science instruction in K-2 classrooms in rural school districts. The research specifically examined changes in (a) teachers' content knowledge in science; (b) teachers' self-efficacy related to teaching science; (c) classroom instructional time allotted…

In this study we described an action research project enacted by a veteran Kindergarten teacher (Sarah) in the context of a professional development program. Over the course of a year, Sarah collaborated with other teachers in a small group to investigate how to use "Science Talks" to promote student learning in Kindergarten classrooms. A…

This study explores how elementary teachers perceive and use "engaging oral strategies" (i.e., manners of speaking that encourage students to participate and become engaged in science discussions). It is reported that the strategies employed as well as their frequency varied substantially depending upon on the teachers' grade level and…

This case study of a midwestern school district's reform effort explored the treatment fidelity of the Science: Parents, Activities, and Literature (Science PALs) project. Data were collected from the perspectives of three stakeholders: students, school district, and parents. Students' and school district supervisor's perceptions indicated that…
