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…

There is growing recognition of the prevalence of "within school churn", a phenomenon in which teachers remain within a school but are assigned a new grade level or course. In this study we examine the consequences of within-school churn for the pedagogical content knowledge of elementary teacher participants in an NSF-funded science PD…

With the growing adoption of the Next Generation Science Standards across the United States, elementary teachers are being called upon to incorporate engineering into their science instruction, creating a need for ways to help elementary teachers better understand what engineering is and how to accurately communicate it to students. The present…

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 paper reports findings from a two-year investigation on the impact of a professional development (PD) program on second grade teachers' science teaching practice, particularly of the Next Generation Science Standards Science and Engineering Practices (NGSS SEPs). The aims of this study were three-fold: 1) identify which SEPs teachers enacted…

Engineering design activities are a common way for teachers to incorporate engineering into their science classrooms, as called for by current science policy documents in the United States. However, little is known about how teachers prioritize different learning objectives during engineering design lessons. Understanding teachers' thinking on…

This study investigated how contextual factors influenced the sustainability of outcomes from a 3-year, state-funded professional development program that provided science assistance for K-2 teachers in small, rural school districts. The research used a case-study approach with a purposive sample of five elementary schools that varied in…

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…

In this study, pupils' understanding of chemical change was investigated in relation to two cognitive variables: logical thinking and field-dependence/field-independence. The participants (N = 99) were sixth-grade elementary school pupils (aged 11/12), which were involved in two different tasks related to combustion. The pupils were tested for…

This paper describes a randomised educational experiment (n = 47) that examined two different teaching methods and compared their effectiveness at correcting one science misconception using a sample of trainee primary school teachers. The treatment was designed to promote engagement with the scientific concept by eliciting emotional responses from…
