In this article, the authors describe their use of simultaneous observations of the 2016 transit of Mercury made from two widely separated locations on Earth to determine the distance to the Sun in a way different from that suggested in 1715 by Halley. Using an internet link, teachers and students can make a similar derivation at the 2019 transit…

Over the course of six years, a diverse group of school districts and charter management organizations in California ran a substantial experiment in implementing the Next Generation Science Standards (NGSS) in elementary and middle grades. WestEd led an extensive evaluation of that effort, the California K-8 NGSS Early Implementers Initiative,…

Recent policy reports and standards documents advocate for science teachers to adopt more student-centered instructional practices. Four secondary science teachers from one school district participated in a semester-long video club focused on honing attention to students' evidence-based reasoning and creating opportunities to make students'…

This study assesses the reliability of two observation rubrics, one in math and the other in science, and documents how the rubric data were used to inform a teacher education program. Classroom observations are typically considered essential for assessing teaching practice, yet many popular observation frameworks, while comprehensive in aim, do…

Introductory science, math, and engineering courses often have problems related to student engagement, achievement, and course completion. To begin examining these issues in greater depth, this pilot study compared student engagement, achievement, and course completion in a small and large section of an introductory biology class. Results based on…

This is a descriptive, exploratory, qualitative, collective case study that explores the pedagogical practices of science teachers who do not hold natural science degrees. The intent of this study is to support the creation of alternative pathways for recruiting and retaining high-quality secondary science teachers in K-12 education. The…

The physics instruction at UC Davis for life science majors takes place in a long-standing reformed large-enrollment physics course in which the discussion or laboratory instructors (primarily graduate student teaching assistants) implement the interactive-engagement (IE) elements of the course. Because so many different instructors participate in…

Background: Acute physical activity breaks lasting 10--60 min have been related to positive effects on student focus and academic performance. The aim of this study was to evaluate the impact of repeated brief physical activity-infused academic lessons (1-5 min) on student retention and on-task behavior. Methods: One class from each K-2 grade…

In this article, we examine classroom observations from a 3-year large-scale randomized trial in the Los Angeles Unified School District (LAUSD) to investigate the extent to which a professional development initiative in inquiry science influenced teaching practices in in 4th and 5th grade classrooms in 73 schools. During the course of the study,…

Thirty preservice teachers enrolled in a field-based science methods course were placed at a public elementary school for coursework and for teaching practice with elementary students. Candidates focused on building conceptual understanding of science content and pedagogical methods through innovative curriculum development and other course…

This study examined the extent to which significant changes after one year of a longitudinal, state-funded teacher professional development program were sustained during the second year. Participants taught in elementary schools located in small, rural school districts in the state of California in the United States. The research examined changes…

This year-long, quasi-experimental study investigated the impact of the use of netbook computers and interactive science software on fifth-grade students' science learning processes, academic achievement, and interest in further science, technology, engineering, and mathematics (STEM) study within a linguistically diverse school district in…

Much has been written recently about the role of talk in content-area learning, including science learning. However, there is still much to be learned about how teachers begin to engage students in the kinds of peer-to-peer conversations that help them make sense of their investigations in science and that advance their conceptual understandings.…

The Community Science Workshops (CSWs)--with funding from the S.D. Bechtel, Jr. Foundation, and the Gordon and Betty Moore Foundation--created a network among the CSW sites in California. The goals of the CSW Network project have been to improve programs, build capacity throughout the Network, and establish new sites. Inverness Research has been…

The continued downward spiral of enrollment in physical sciences in the USA and Europe has science educators concerned on both sides of the Atlantic. Physics has been particularly hard-hit, with the percentage of students choosing to major in the subject at the lowest level in decades. University physics has a reputation as a difficult, abstract…
