In physics education, a number of studies have developed assessments of teachers' knowledge of student understanding (KSU) of specific physics concepts with modified versions of existing concept inventories, in which teachers were asked to predict the popular incorrect answers from students. The results provide useful but indirect information to…

One of the most important problems of today's science education is the misconceptions and lack of knowledge that arise due to the science concepts not being learned in depth and meaningfully. For this reason, in this study, misconceptions, lack of knowledge, and scientific knowledge levels of science teachers about liquid pressure, which is one of…

The study assessed the science teaching confidence of preservice teachers in teaching elementary science by addressing two research questions: (1) Did preservice teachers understand the science concepts well enough to be effective in teaching elementary science content? (2) Did preservice teachers have the necessary science concepts and skills to…

An empirical investigation of elementary school teacher candidates on classification activities dealing with animate and inanimate objects in terms of being living or non-living demonstrates that as the size of the objects increases, subjects are more likely to classify them correctly as either being an animal or having living characteristics.…

In science education, it is vital for teachers to consider students' academic and emotional needs. Teachers' prediction of students' learning states has been commonly regarded as an indicator to measure that competence to understand students. This study aimed to explore the outcome and the process of prediction to reflect teachers' pedagogical…

In this study, a 'biotechnology literacy test' was developed to determine the biotechnology literacy of prospective science teachers, and its validity and reliability were determined. For this purpose, 42 items were prepared by considering Bybee's scientific literacy classifications (nominal, functional, procedural, and multidimensional). The…

This work reports a classroom experience of a general physics course designed to foster also the initiation of preservice mathematics and biology teachers to physics pedagogical content knowledge. To modify the conceptions that these students have about teaching and learning, the course was taught using different active learning instructional…

Combined three-dimensional, haptic-enabled, virtual reality (3D HE VR) systems allow students to actively engage and explore various science concepts by leveraging user-friendly and immersive interfaces. Successful implementation of these learning tools in science classrooms hinges upon teachers' perceptions of the technology's potential as a…

The purpose of this report is to examine the performance of assessment items designed to measure elementary teachers' content knowledge for teaching (CKT) science as part of the ETS® Educator Series. The Elementary Education: CKT Science assessment is 1 component of licensure examination through the PRAXIS® assessments. The Elementary Education:…

This research aimed at evaluating pre-service science teachers' understanding of the subject matters such as "thermochemistry, chemical kinetics, chemical equilibrium, acids and bases and electrochemistry". For this purpose, a two-tier diagnostic test consisting of 44 items ([alpha] = 0.84) related to the aforementioned concepts was…

In this study, we sought to examine the influence of a 12-week design-based elective Science, Technology, Engineering, and Mathematics (STEM) course on pre-service chemistry teachers' content knowledge, STEM conceptions, and engineering and engineering design views. To attain the goals determined, we utilized five STEM activities starting with a…

Scientific reasoning competencies are relevant science competencies and therefore the development of assessment instruments for scientific reasoning competencies has become an integral part of science education research. However, some authors have questioned the validity of the instruments available so far, since their psychometric quality has not…

This study investigated the differences between Taiwanese experienced and preservice elementary school science teachers' content knowledge (CK) about electric circuits and their ability to predict students' preconceptions about electric circuits as an indicator of their pedagogical content knowledge (PCK). An innovative web-based recruitment and…

This paper analyzed the costs and benefits of attending the top three U.S. elementary teacher education programs by examining how much emphasis is on general content knowledge (GCK), as opposed to general pedagogical knowledge (GPK), as opposed to methodological pedagogical knowledge (MPK), and how this ratio might have affected student outcomes…

Research exploring the possible link between quality of argumentation and content knowledge is not straightforward. Some studies suggest a positive relationship (e.g. Dawson & Schibeci in "J Biol Educ" 38(1):7-12, 2003) while others do not (e.g. Zohar & Nemet in "J Res Sci Teach" 39:35-62, 2002). This study examined the…
