This study investigates challenges of enactment teachers notice when analyzing artifacts of teaching in a professional development focused on supporting the enactment of NGSS-aligned modeling instruction. Five secondary science teachers participated in a semester-long video club. Transcripts of the segments of their meetings in which they analyzed…

This research with middle school students from Kentucky (KY) and Nevada (NV) provides a snapshot of students' spatial-scientific understandings as we explored how well students understand lunar-related content, both spatially and scientifically, after receiving instruction with similar curricular Earth-Space content. Utilizing a lens of spatial…

Curriculum materials can play a major role in shaping teachers' thinking about instruction and content as well as serve as a support for teachers' learning. With the inclusion of engineering in NGSS, many teachers may be turning to existing curriculum materials to help them infuse engineering into their science classroom, especially when they do…

The goal of this article is to inform professional understanding regarding preservice science teachers' knowledge of engineering and the engineering design process. Originating as a conceptual study of the appropriateness of "knowledge as design" as a framework for conducting science teacher education to support learning related to…

Findings from physics education research strongly point to the critical need for teachers' use of multiple representations in their instructional practices such as pictures, diagrams, written explanations, and mathematical expressions to enhance students' problem-solving ability. In this study, we explored use of problem-solving tasks for…

Professional development (PD) programs focused on increasing teachers' use of formative assessment generally provide a framework designed to help teachers understand the breadth and complexity of formative assessment, while advocating for teacher choice with respect to the specific implementation. This study examined the implementation patterns of…

Effective professional development that influences teachers' classroom practices starts with what teachers know, understand, and do in their classroom. The Next Generation Science Standards (NGSS) challenge teachers to make changes to their classroom; to help teachers make these changes, it is necessary to know what they are doing in their…

Before we can effectively apply specific interventions through professional development, it is important to determine what is occurring in our high school physics classrooms. This study investigated common professional practices in physics teaching among a representative sample group of schools and teachers from a diverse, geographically large…

This study examines what students enrolled in the honors and general sections of a high school biology course offered at the same school learn when they have an opportunity to participate in a broad or narrow range of science practices during their laboratory experiences. The results of our analysis suggest that the students enrolled in the…

This article examines the process of shifting to a "Physics First" sequence in science course offerings in three school districts in the United States. This curricular sequence reverses the more common U.S. high school sequence of biology/chemistry/physics, and has gained substantial support in the physics education community over the…

Knowing what students bring to the classroom can and should influence how we teach them. This study is a review of the literature associated with secondary and postsecondary students' ideas about acids and bases. It was found that there are six types of alternate ideas about acids and bases that students hold. These are: macroscopic properties of…

Previous literature suggests that service learning may offer new opportunities to support the development of preservice science and math teachers, but few studies examine service learning beyond isolated teaching events. In this qualitative study, we attempt to improve upon this literature by following Master of Arts in Teaching (MAT) students'…

Middle and secondary science textbooks have long been a primary support for instruction, often leading to heavy emphasis on domain-specific vocabulary. A longitudinal study was conducted to compare vocabulary loads of science textbooks published since 2010 to results of two previous studies going back to 1983. In each study, textbooks chosen…

Objective: In this study, we investigated the implementation of project-based learning (PBL) activities in four secondary science, technology, engineering, and mathematics (STEM) education settings to examine the impact of inquiry based instructional practices on student learning. Method: Direct classroom observations were conducted during the…

The main purpose of this quantitative study was to examine the degree to which a three-week intervention in an urban high-needs high school science classroom would influence students' (n = 51) interest, utility value, content knowledge, and intentions for future study in chemistry. The intervention consisted of an authentic, inquiry-based…
