This paper is part of the special issue on Teacher Learning and Practice within Organizational Contexts. Shifting instructional practices in elementary schools to include more equitable, reform-based pedagogies is imperative for supporting students' development as science learners. Teachers need high quality professional development (PD) to learn…

This longitudinal study examines elementary teachers' self-efficacy for science teaching in the years after professional development (PD) ended and during a subsequent 3-year period of follow-up support. Self-efficacy is important because teachers make decisions about classroom activities based, in part, on how confident they are in their…

Given the time and resources invested in professional development, it makes sense to find ways to extend positive outcomes over the long term. However, there is little research investigating what elements and structures help to support teachers once professional development ends. This research is based on an intervention of modest, targeted forms…

Background: The Framework for K-12 Science Education (NRC, 2012) and Next Generation Science Standards ([NGSS] NGSS Lead States, 2013) emphasize that all students from the earliest grades onward must have the opportunity to learn and actively participate in authentic science. In K-12 science instruction, this means that students should have the…

Traditional teacher professional development (PD) programs frequently lack sufficient face-to-face preparation time to adequately support the implementation of evidence-based pedagogical strategies in classrooms, with teachers citing insufficient preparedness and training time for new methods. To investigate potentials for online PD methods to…

The adoption of the Next Generation Science Standards (NGSS) has brought with it a need for classroom assessments that measure students' ability to make sense of, explain, and use science, with many of the performance expectations asking students to apply scientific principles and evidence to produce an explanation. But creating coherent written…

The authors of this article have participated in intensive professional development in the Peruvian Amazon and brought this firsthand experience of the rainforest back to their classrooms. However, the activities presented in this article are designed to be accessible and inspirational to "all students," regardless of whether they or…

[This paper is part of the Focused Collection on Curriculum Development: Theory into Design.] A level of curricular design, called "design tactics," is identified to fill a gap in the research literature between the broad principles that guide curriculum development and the detailed writing of specific activities and lessons. The use of…

Finding context, examples, and ample hands-on experimentation is fundamental for understanding complex ideas in subjects such as science and math. Recent popularity of competitive robotics has become a catalyst in the development of DIY and hobby kits. Manufacturers have made available easy to work, re-configurable, and functional, structural…

An active-learning concurrent preparatory general chemistry course was adopted to replace a prerequisite course that lacked effectiveness in improving student outcomes. Our previous study showed that the concurrent course increased final exam performance and retention in a cohort of students. This paper studies the course modality impact of the…

Community colleges are a major entry point for many students to post-secondary education, particularly for minority, first-generation, low-income, and older students. A range of factors including transfer-readiness, curricular alignment, financial barriers, and transfer guidance, influence successful transfer between two-year colleges (2YCs) and…

The California Next Generation Science Standards (CA NGSS) Toolkit for Instructional Materials Evaluation (TIME) is a suite of tools and processes for evaluating and selecting instructional materials aligned with the CA NGSS. This 11th report in the NGSS Early Implementers Initiative evaluation series is intended for school and district…

Providing science instruction is an ongoing priority and challenge in elementary grades, especially in high-need rural schools. Nonetheless, few studies have investigated the factors that facilitate or limit teachers' science instruction in these settings, particularly since the introduction of the Next Generation Science Standards. In this study…

Considerable evidence suggests that dialogical interaction in the classroom promotes students' scientific knowledge building and reasoning. Hence, scientific argumentation is recognized as a central component of the Next Generation Science Standards. A focus on argumentation, however, requires teachers to adopt instructional practices that…

This article reports an investigation of a professional development program to enhance elementary teachers' ability to engage their students in argument from evidence in science. Using a quasi-experimental approach, three versions were compared: Version A--a 1-week summer institute with a 2-week summer practicum experience and 8 follow-up days…
