Cultivating in preservice science teachers (PSTs) the competence required to teach scientific models and modeling is a valued outcome of teacher preparation programs. However, science teacher educators face inherent tensions when designing and implementing teacher preparation experiences to achieve this outcome. In this systematic review, we first…

Professional development (PD) can support science teachers to learn about instructional reforms, but more work needs to be done on broadening our understanding of how specific PD activities support teacher learning. One understudied PD activity is the "student hat": when teachers engage in student learning activities while considering…

The assessment of Nigerian teachers' climate science literacy and training needs on climate change concepts (i.e., causes, impacts, and solutions) are absent. This study relates teachers' climate science literacy and their expressed training needs in other climate change concepts and places teachers in groups. Following a descriptive survey…

The present study seeks to identify teachers' perceptions regarding STEM teaching professional development and to identify the factors that facilitate or hinder the success of teachers' professional development. The participants of the study were 35 teachers. A qualitative approach was used for data collection by conducting semi-structured…

Engineering offers new educational opportunities for students, yet also poses challenges about how to conceptualize the disciplinary core ideas, crosscutting concepts, and science and engineering practices of the disciplinary fields of engineering. In this paper, we draw from empirical studies of engineering in professional and school settings to…

Argumentation, a key epistemic practice in science, engages students in socially constructing knowledge claims using evidence. However, teachers need support in integrating argumentation into classroom instruction. We examined teachers' enactments of an educative science curriculum and their curricular decision making for argumentation. Ten middle…

This multicase study examines how three teachers enacting ambitious instruction purposefully designed and used their classroom as a "place of science" in which students participated in disciplinary practices. A place of science is a location that shapes the norms, values, and history of disciplinary practices. Each participant's…

National and international large-scale assessments (LSA) have a major impact on educational systems, which raises fundamental questions about the validity of the measures regarding their internal structure and their relations to relevant covariates. Given its importance, research on the validity of instruments specifically developed for LSA is…

Research on science teacher cognition is important as findings from this research can be used to improve teacher training, leading to improved classroom practice. Previous research has often relied on two underlying assumptions: Cognition is an individual process, and these processes are detailed and introspective. In this paper, we put forth a…

We teach a course for elementary education undergraduates that gives students an opportunity to conduct open-ended scientific inquiry and pursue their own scientific questions in much the same way that practicing research scientists do. In this study, we compared what our students say declaratively about the nature of science (NOS) in surveys and…

Despite being identified as an essential scientific practice, argumentation is rarely integrated into instruction. This could be influenced by teachers' pedagogical design capacity (PDC), which considers teaching as a design activity influenced by both instructional resources (such as tools and professional development (PD)) and teacher resources…

This article examines the use and role of the term "experiment" in science teacher education as described by teacher students. Data were collected through focus group interviews conducted at seven occasions with 32 students from six well-known Swedish universities. The theoretical framework is a sociocultural and pragmatist perspective…

This research used multilevel modeling to investigate the perceived effect of a teacher preparation loan forgiveness program on recruiting science and mathematics majors to become teachers and teach in high-need schools. The study investigated how and which personal perceptions, characteristics, and teacher preparation program variables influenced…

The processes of change in teachers' practice have been the subject of many studies in educational research. We here describe a case study of long duration (in a course of time of 9 years) that has allowed us to gain some insight into how they occur and the underlying obstacles making the processes so slow. We take the professional development of…

Given the impact of textbooks on learning, this study assesses the five most frequently used secondary school biology textbooks in Turkey to examine the nature and the quality of treatment given to the nature of science. A qualitative oriented approach was employed and ethnographic content analysis was used as the methodological framework for this…
