The purpose of this study was to conceptualize a pedagogical content knowledge framework for informal science educators (ISE-PCK). An initial, hypothetical framework was created grounded in the literature in informal science education (ISE) as analogous to PCK models in formal science education. An exploratory sequential mixed-methods research…

Teachers' understanding and teaching of argumentation is gaining more attention in science education research. However, little is known about how science teachers engage in argumentation with teachers of different subject taking an interdisciplinary perspective that may inspire new pedagogical ideas or strategies. In particular, the positioning of…

This article utilizes a framework for classifying different scientific methods suggested by a philosopher of science (Brandon "Synthese," 99, 59-73, 1994) called Brandon's Matrix. It presents findings from teachers who took part in a funded project in England that looked at the nature of scientific methods in science investigations.…

While technology advancement and scientific innovation have created new topics and fields of inquiry in STEM education, external content experts such as university scientists/researchers have been increasingly involved to enhance K-12 teachers' disciplinary understandings and professional development (PD). However, few studies have scrutinized…

Science classroom learning environment (CLE) and science teacher professional development (PD) are two important factors in students' science learning. However, the nature of the science CLE and school-level PD that promotes students' science achievement remains unclear. Using the Program for International Student Assessment (PISA) 2015 data, this…

Teachers' development can be seen as a dialog between their reflective thinking and their actions, with an added gradient of complexity from their social interactions. All of these elements are conjugated within their classroom practice, with their Pedagogical Content Knowledge (PCK) as theoretical background. This paper analyzes the case of a…

This study examined the preferences for professional development (PD) in primary (elementary) science among pre-service teachers (PSTs) and in-service teachers (ISTs). The contribution of the study is its focus on quantifying the relative importance of factors that were significant for teachers by using best-worst scaling methodology. Rather than…

Many nature of science (NOS) studies have demonstrated that teachers can improve their understandings of NOS with explicit and reflective instruction; however, the field has relied heavily on qualitative methods. Because qualitative studies can be difficult to compare across studies and contexts, our study sought to determine if a quantitative…

This paper reports a pretest-posttest study about the impact of a teacher professional development (TPD) programme on primary school teachers' knowledge of and attitude towards inquiry-based learning. A pedagogical framework of inquiry phases and domains of scientific knowledge combined with hard and soft scaffolds formed the basis for the TPD…

The adoption of engineering design-based science teaching requires elementary teachers to modify their current science pedagogy, often resulting in tensions or hard choices they must make in their teaching practice. The purpose of this study is to identify, compare, and characterize the tensions faced by 45 grade 3 and grade 4 elementary teachers…

This study investigated science classroom discourse in terms of the types of teacher discursive moves (TDMs) and the relationships between the types of TDMs and student-led cognitive contributions in different science concepts by considering the classroom context. An experienced seventh-grade science teacher and her 19 students were engaged in…

This study evaluated the effectiveness of the Mathematics Infusion into Science Project (MiSP), which integrated science and mathematics in an engaging middle school science curriculum that fostered improvements in science content knowledge, higher-level problem solving, and affective domains related to mathematics. The project design was based…

We investigate in-service teachers' scientific engagement in a blended online science inquiry course. We analyze a shift from teachers following instructions to doing science themselves, and we characterize it at two levels: first, in how teachers engaged in individual sense-making; and second, in how they oriented to the online community as a…

This paper explores the effect teachers' participation in a targeted inquiry-based/nature of science (NoS) continuing professional development programme had on Irish primary children's experiences of scientific inquiry and developing conceptions of NoS. Data were gathered from 459 children from 10 Dublin schools. The findings revealed that their…

A growing body of research suggests that student-centered teaching methods are associated with positive learning outcomes for undergraduate students. Yet, the extent of their use and factors leading to their adoption in fields, such as chemistry, continue to be under-explored. Utilizing survey data collected during 2015, we begin to fill this gap,…
