STEM (Science-Technology-Engineering-Mathematics) education has received great attention in recent years not only for promoting interest and learning in these areas but also for encouraging children and young people to pursue careers in them. This research explored the effects of a STEM program in developing the primary pre-service teachers'…

The purpose of this paper is to address the most significant contributions of pedagogical content knowledge (PCK) involved in teaching physics. Most studies have observed the characterizations of PCK via specific content in the lower secondary and upper secondary curricula. Here, we present a number of studies that show evidence for the…

For the planning and implementation of lessons with digital technologies, a subject-specific technology-related professional competence of teachers is of central importance. However, the competency frameworks developed so far remain in a general perspective and do not explicitly address subject-specific issues. Furthermore, digital competencies…

Lifestyle sports can contribute to national sport and physical activity agendas. However, schools in the United Kingdom (UK) have generally resisted the implementation of such activities within the physical education (PE) curriculum. This may stem from PE teachers' limited knowledge and restricted engagement with lifestyle sports continuing…

This study compares three pre-collegiate teacher professional learning and development (PLD) integrated science, technology, engineering, and mathematics (STEM) experiences framed in astronomy. The study is set in the western United States (USA) and involves 60 pre-collegiate teachers (in the USA these are K-12 teachers) over the course of three…

At the beginning of the COVID-19 pandemic in spring 2020, school and university learning were abruptly switched to distance learning, coming along with psychological strains and various learning lags on the part of the students. These problems come to a head when focusing on university teacher students, since an expectable competence lag on their…

We present a study on teacher education and, in particular, on Physics. Our assumption is that General Didactics and Disciplinary Didactic constitute two fundamental components of teachers' professional development and therefore both must be used to interpret didactic phenomena adequately. This research involves a sample of 274 prospective…

Understanding and knowledge of scientific reasoning skills is a key ability of pre-service teachers. In a written survey (open response format), biology and chemistry pre-service teachers (n = 51) from two German universities claimed central decisions or actions school students have to perform in scientific reasoning in the open inquiry…

Teachers' diagnostic competences are essential with respect to student achievement, classroom assessment, and instructional quality. Important components of diagnostic competences are teachers' professional knowledge including content knowledge (CK), pedagogical knowledge (PK), and pedagogical content knowledge (PCK), their diagnostic activities…

The professional competencies pre-service geography teachers acquire in university influence their contribution to education for sustainable development (ESD) in their future school careers. We assessed pre-service geography teachers' (n = 100) competencies and attitudes towards the official, German ESD orientation framework to determine the…

"Chemish," as the scientific language of chemistry, is essential for communicating in and understanding chemistry. At the same time, Chemish is one of the major difficulties in teaching and learning chemistry in the school context. Although in recent years the importance of language in general and scientific language in particular has…

The United Nations Sustainable Development Goal (SDG) number four seeks an equitable and widespread education that enables an outcome of sustainable development by 2030. Intersecting the studies of society and earth processes, a geographical education is well placed to make cohesive sense of all the individual knowledge silos that contribute to…

This paper discusses a model of a mathematics teacher professional development implemented in Italy and Hungary with in-service and pre-service mathematics teachers. The model focuses on comparative geometry, and it develops with the use of an artifact: the Lénárt spheres. The teacher training model is the result of several years of experience of…

The "leaky pipeline" in STEM remains an open issue. The integration of multiple STEM subjects, especially technology, is a promising approach, and pre-collegiate STEM teachers are particularly underprepared in this content area. In this case study, the authors explore and characterize the discussions of pre-collegiate STEM teachers among…

Since the development of the technological pedagogical content knowledge (TPACK) framework, researchers have been developing a variety of instruments to measure the TPACK of pre-service and in-service teachers. The task of developing an efficient, reliable, and valid instrument is difficult. Even validated instruments require guidance for…
