Despite the importance of developing elementary science teachers' content knowledge for teaching (CKT), there are limited assessments that have been designed to measure the full breadth of their CKT at scale. Our overall research project addressed this gap by developing an online assessment to measure elementary preservice teachers' CKT about…

Teacher knowledge is vital to provide meaningful learning opportunities. In this case study, a secondary education teacher's knowledge about how to teach the concept of ecosystems from a river is explored. A category system drawn from the literature about science teacher knowledge was used for the analysis. Science teaching requires teachers to…

Presenters' pedagogical choices are strongly affected by whether they view knowledge as coherent or fragmented. This mixed-methods survey study seeks to contribute to epistemological discussions and associated pedagogical suggestions in the context of mole ratio related mistakes evident in stoichiometry calculations performed by in-service…

With the 2015 change in science standards to align more closely with the Next Generation Science Standards, as the district STEM coach, I saw a need for professional development that addressed the lack of understanding and skill needed to teach the Science and Engineering Practices, specifically the practice of Scientific Augmentation. This…

Addressing student conceptions is crucial in science education. Therefore, teachers should be able to notice and interpret situations, in which student conceptions are part of the complex classroom interactions. This study analyzes the skills known as professional vision using an interpretivist research paradigm and a sociocultural perspective.…

In this paper, we describe a study on tasks following the construct of school-related content knowledge. We know from previous studies that such tasks were rated by the preservice chemistry teachers as important for their future profession. Those studies were conducted in a traditional course on organic chemistry which was organized around…

Content knowledge (CK), pedagogical content knowledge (PCK) and, assessment knowledge (AK) are fundamental types of teachers' knowledge. Second-career, pre-service chemistry teachers leave the industry and return to the Technion to study in the "Views" program to obtain a high school teaching certificate. Their background can potentially…

This study examines future secondary physics teachers' knowledge related to the teaching of sound waves, and specifically the topics of sound level and sound intensity. The data is comprised of future teachers' responses to a task in which they had to compose a script for an imaginary dialogue between a teacher and a group of students and to…

This research aims to compare three kinds of knowledge of cognition underlying the reflective aspects of metacognition. The three kinds of cognition considered in this research are declarative knowledge, procedural knowledge and conditional knowledge. This exploratory research survey involved 122 pre-service biology teachers during their third…

Not all instructors implement active-learning strategies in a way that maximizes student outcomes. One potential explanation for variation in active-learning effectiveness is variation in the teaching knowledge an instructor draws upon. Guided by theoretical frameworks of pedagogical content knowledge and pedagogical knowledge, this study…

The study examined level of awareness and extent of utilization of innovative instructional strategies by science teachers for teaching science in senior secondary schools in Kebbi State, Nigeria. The research is quantitative in nature, descriptive survey research design was adopted. A sample of 252 science teachers was drawn from all science…

Results from a national needs assessment survey advertised through science teacher networks with the title "Polar Education--Teacher Input Needed" showed that the majority (90%) of teachers that responded are teaching about polar topics or polar regions. We received 508 responses from elementary to post-secondary teachers across the…

This study explored the teacher knowledge manifestation of Integrated Science (IS) teachers who have specialised in Chemistry, Biology or Physics during their pre-service teacher education. 60 experienced Integrated Science teachers responded to an 'Integrated Science Teacher Knowledge' questionnaire which embraced different dimensions of teacher…

This study reveals the transformation of prospective science teachers into knowledgeable individuals through classical, combination, and information theories. It distinguishes between knowledge and success, and between knowledge levels and success levels calculated each through three theories. The relation between the knowledge of prospective…

In this paper, we examined teachers' understanding of electrical concepts such as power, current and potential difference based on how these concepts were applied to understand the relative brightness seen in bulbs of different wattage under different connections--series or parallel. From the responses of teachers to a concept question, we…
