A mixed-methods, quasi-experimental design was employed to explore how the Claim, Evidence, and Reasoning (CER) framework along with written, verbal, and peer scaffolds would influence early childhood/elementary and elementary/middle childhood preservice teachers' (PSTs) abilities to formulate scientific explanations within a physical science…

Drawing on a sociocultural understanding of identities as multiple and fluid, we investigate how six practicing teachers recruited their biographical resources in constituting their discourse identities in interviews. The South African context allows us to consider how systemic inequality shapes the identity resources available to teachers from…

In the last 30 years, there has been an ongoing discussion about the effectiveness of Professional Development (PD) programs, which aims to promote reform-based Science Education (SE). Among the many, different trends of reform-based science teaching, inquiry-based approaches hold a dominant role. This study shows how teachers' practices were…

Scientific knowledge is necessary to make informed decisions about many social issues, but some of the public is skeptical of science and scientific expertise. Teacher education programs are one way to address distrust in science in this generation and the next. Socioscientific issues (SSI) have been advocated as important for teaching about the…

This study investigated in what ways and to what extent the interactions between the components of pedagogical content knowledge (PCK) differ for junior high school science teachers with different levels of content knowledge. Data were collected from three science teachers through semi-structured interviews and classroom observations. The…

Although the "Next Generation Science Standards" and the "National Science Education Standards" prioritize the production of critical consumers of science as an overarching goal, there is relatively little science education research aimed at fostering critical perspectives among science teachers. The purpose of this…

Developing knowledge about science instruction is critical for preservice teachers. This study explores how 79 elementary preservice teachers perceive the relevance and importance of assessment task scenarios designed to elicit information about content knowledge for teaching (CKT) about matter and its interactions--a foundational topic for…

The goal of this qualitative study was to examine how non-STEM teachers worked to find their place in a K-12 school district implementing a district-wide STEM initiative. Teachers of individual STEM disciplines have been found to struggle with curricular integration, a key focus of many STEM initiatives. A yet unexplored question around STEM…

In an effort to deepen learning in K-12 science classrooms, there has been a national movement to integrate computational thinking (CT). The purpose of this phenomenographic study was to understand teachers' perceptions of the function and usefulness of a task analysis and a decision tree tool designed to help them with integration. Teachers…

Specialized science courses (SSCs) integrate content knowledge (CK) with pedagogical content knowledge (PCK) and prepare pre-service teachers (PSTs) for reform-oriented teaching. Studies of individual SSCs report positive short-term outcomes, including an increase in self-efficacy and CK. However, few studies explore the longer-term impact of SSCs…

The aim of this study is to examine the relationships between pre-service teachers' critical thinking skills and their self-efficacy for argumentation. The participants of the research consisted of 858 pre-service teachers (447 female, 411 male) studying in education faculties at five different state universities in Turkey. In this study, the…

This study explored how preservice teachers engaged in collaborative inquiry with elementary students to facilitate social justice and equity in science education. By inviting elementary students as key stakeholders into collaborative inquiry, we examined how preservice teachers uncovered critical problems of science education in underserved…

There is a high need for well-qualified teachers across all STEM content areas, especially in secondary physics. Our work examines why individuals choose to pursue physics teaching. This study, at a primarily undergraduate institution in the Northeastern United States, uses a modified version of Watt and Richardson's Factors Influencing Teacher…

Elementary students' interest in science and careers in STEM are typically associated with their curiosity along with engagement in science activities and whether they find these activities to be fun, exciting, and enjoyable. Thus, early exposure of elementary students to STEM lessons must be engaging and enjoyable, which in turn increases the…

Video analysis of teaching episodes is a widely-used approach in science teacher education. While numerous scholarly articles have been written on the topic, there are still many unanswered questions about the most effective strategies for integrating this approach into science teacher education. The current article adds to this area of inquiry by…
