We present a model for Professional Development (PD) for in-service generalist primary teachers of science. The Remote Classroom Modelling (RCM) model is specifically designed to address salient challenges in the context of professional isolation. We share the principles that supported the design of this PD prototype, and the insights and lessons…

Researchers have typically identified and characterized teachers' knowledge bases (e.g., pedagogical content knowledge and subject matter knowledge) in an effort to improve enacted instructional strategies. As shown by the Refined Consensus Model (RCM), understanding teacher learning, beliefs, and practices is predicated on the interconnections of…

Teachers make many important decisions about instruction during the process of planning. While educational researchers have extensively explored teacher planning, this research has largely neglected the ways teachers attend to subject matter while planning. We first explore ways a sample of 13 experienced secondary biology teachers attend to…

This study aims to develop, implement, and evaluate an instructional design model to enhance the pedagogical content knowledge (PCK) of physics student teachers. Model development is accomplished in five stages over two years: 1) problem identification, 2) preliminary identification of the product and design concepts, 3) preliminary theories and…

As educational accountability pressures and science teacher attrition rates within American public-school systems continue to rise, so does the need for improved reform-based professional development (PD) opportunities that allow science educators to challenge their pedagogical beliefs and teaching practices. This qualitative case study explores…

Compelling evidence, from multiple levels of schooling, suggests that teachers' knowledge and beliefs about knowledge, knowing, and learning ("i.e.," epistemologies) play a strong role in shaping their approaches to teaching and learning. Given the importance of epistemologies in science teaching, we as researchers must pay careful…

There is a collective agreement about the necessity of content knowledge (CK) as a prerequisite for pedagogical content knowledge (PCK). However, most PCK models lack explanatory power because of the missing link between CK and PCK. Thus, the study firstly attempts to develop a theoretical model that consists of knowledge of students' learning…

The purpose of this longitudinal study was to explore the development of pre-service chemistry teachers' pedagogical content knowledge regarding the effect of temperature on reaction rate topic as they took pedagogical content knowledge courses throughout the teacher education program. Pre-service teachers' pedagogical content knowledge was…

Scientific modeling is a scientific practice that uses models to prepare elementary and middle school science teachers to engage students using scientific inquiry. Model-based inquiry (MBI) is a pedagogical teaching approach that engages students using scientific inquiry during scientific modeling. However, preservice teachers lack understanding…

As part of their professional competencies, science teachers need an elaborate meta-modelling knowledge as well as modelling skills in order to guide and monitor modelling practices of their students. However, qualitative studies about (pre-service) science teachers' modelling practices are rare. This study provides a category system which is…

The structure and definition of professional knowledge is a continuing focus of science education research. In 2012, a pedagogical content knowledge (PCK) summit was held and it suggested a model of professional knowledge and skill including PCK, which was later often called the Consensus Model (Gess-Newsome, 2015. A model of teacher professional…

Collaboration between teachers and academics can have a sustainable impact on teachers' professional development. Accordingly, the aim of the study was to investigate the effect of the academic counseling model (ACM) based on academic-teacher collaboration on the pedagogical content knowledge (PCK) of in-service teachers. The ACM consists of five…

Professional knowledge for science teaching develops over time and interplays with professional experiences in field. In the present study, we explore student teachers' reflective conversation upon teaching experiences, with pedagogical content knowledge, PCK, as an analytical lens. The empirical data is based on nine meetings, with groups of 3-6…

Recent research and reform efforts in science education have consistently stressed the importance of coherent science instruction, in which learning opportunities are connected and contextualized by meaningful phenomena, focus on a small set of core ideas over time, and generate a need-to-know about new ideas through a set of connected lessons.…

This paper concludes the Special Issue (SI) 'Probing the Amalgam: the relationship between science teachers' content, pedagogical and pedagogical content knowledge'. We review the five papers (Sorge et al; Gess-Newsome et al; Kind; Pitjeng-Mosabala and Rollnick; and Liepertz and Bronowski) by discussing evidence these present regarding the…
