Language is a fundamental tool for learning science. This study highlights the importance of teacher knowledge in utilising language as a tool for knowledge generation in the classrooms. This case study examines elementary teachers' development of declarative, procedural, and epistemic knowledge related to using language, particularly focusing on…

This study asked 241 primary children and their 13 teachers in the Canton of Berne, Switzerland, to identify 136 local plant and animal species, which were shown to them as pictures. Children's age, gender, and experiences with nature were recorded to test for associations with species knowledge. Teachers identified 52% of the plants and 61% of…

Teachers' professional knowledge is considered one of the most important predictors of instructional quality. According to Shulman, such professional knowledge includes content, pedagogical content and pedagogical knowledge. Although recent research shed some light on the structure of the dimensions of professional knowledge, little is known how…

Pedagogical content knowledge (PCK) is central to teachers' professional knowledge impacting student learning and thus is considered a key attribute of teacher quality. Teacher quality is often indirectly examined by proxy measures such as degrees, certification, and teaching experience. To date, little is known how those proxy measures are…

This Special Issue aims to present evidence about the relationships between content knowledge (CK), pedagogical knowledge (PK) and pedagogical content knowledge (PCK); the development of these types of knowledge in novice and experienced secondary science teachers; and how CK, PK and/or PCK impact students' learning. Since Shulman's introduction…

Preschool teachers' science-specific competences have been shown to influence their science instruction, which in turn appear directly related to the development of children's science competences. Initial teacher education and in-service professional development may include learning opportunities to acquire science-specific competences necessary…

During the last decade there has been on-going discussions about students' declining interest and low achievement in science. One of the reasons suggested for this decline is that teachers and students have different frames of reference, whereby teachers sometimes communicate science in the classroom in a way that is not accessible to the…

Science teachers need to understand the subject matter they teach. While subject matter knowledge (SMK) can improve with classroom teaching experience, it is problematic that many secondary science teachers leave the profession before garnering extensive classroom experience. Furthermore, many new science teachers are assigned to teach science…

Science standards in the U.S. have shifted to emphasise science and engineering process skills (i.e. specific practices within inquiry) to a greater extent than previous standards' emphases on broad representations of inquiry. This study examined the alignment between second-career science teachers' personal histories with the latter and examined…

We present results of an experimental study of an urban, museum-based science teacher PD programme. A total of 125 teachers and 1676 of their students in grades 4-8 were tested at the beginning and end of the school year in which the PD programme took place. Teachers and students were assessed on subject content knowledge and attitudes towards…

Aspects of chemistry content knowledge held by 265 UK-based pre-service teachers (PSTs) were probed using 28 diagnostic questions in five chemistry concept areas, "Particle theory and changes of state", "Mass conservation" (taught to 11-14-year-olds), and "Chemical bonding", "Mole calculations" and…

Formative assessment, and especially feedback, is considered essential to student learning. To provide effective feedback, however, teachers must act upon the information that students reveal during instruction. In this study, we apply a framework of formative assessment to explore how sensitive teachers are to students' thoughts and ideas when…

The aim of the research was to investigate the effect of the amount and quality of content knowledge on pedagogical content knowledge (PCK). The biological content photosynthesis and plant growth was used as an example. The research sample consisted of 10 primary and 10 secondary (biology) teacher students. Questionnaires, lesson preparation task…

Teachers' subject matter knowledge (SMK) is one factor contributing to teaching 'successfully', as this provides a basis from which pedagogical content knowledge develops. UK-based trainee science teachers teach all sciences to age 14 and often up to age 16. Trainees have specialist science knowledge in chemistry, physics, or biology from their…

The purpose of this study was to explore the relationships among the components of preservice science teachers' (PSTs) pedagogical content knowledge (PCK) involving the topic "ozone layer depletion". An open-ended survey was first administered to 216 PSTs in their final year at the Faculty of Education to determine their subject matter…
