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…

Chemish - the scientific language of chemistry - is crucial for learning chemistry. To help students acquire the competencies to understand and use Chemish, chemistry teachers need to have a sound knowledge of teaching and learning Chemish: Pedagogical Scientific Language Knowledge (PSLK). But still, despite the importance of this knowledge, the…

In order to reach students who can efficiently use intended scientific understandings, it is important to have science teachers without conceptual difficulties. The aim of present research is to enhance pre-service science teachers' conceptual understanding about boiling by dialogic teaching. The sample consisted of forty-three pre-service science…

Much research has been conducted regarding student alternative conceptions in chemistry, and a significant amount of work has focused on the areas of chemical equilibrium and reaction rates. Less research has focused on teachers' alternative conceptions in these areas, and most of this work has studied the conceptions of pre-service and novice…

Assessing student learning to adapt instruction to support learning is an important skill all teachers need to develop. However, it is not an easy task for teachers and even more difficult for new teachers. The current study aims to explore an alternatively certified new chemistry teacher?s understanding and practices of classroom assessment to…

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…

Background: Textbooks are integral tools for teachers' lessons. Several researchers observed that school teachers rely heavily on textbooks as informational sources when planning lessons. Moreover, textbooks are an important resource for developing students' knowledge as they contain various representations that influence students' learning.…

This study describes the use of the double-slit thought experiment as a diagnostic tool for probing physics teachers' understanding. A total of 9 pre-service teachers and 18 in-service teachers with a variety of different experience in modern physics teaching at the upper secondary level responded in a paper-and-pencil test and three of these…

In the Department of Physics, University of Helsinki, there are advanced physics courses designed for the needs of pre-service physics teachers. The starting point is that after introductory and intermediate physics courses, pre-service physics teachers know laws and definitions but the knowledge is quite fragmented and does not form coherent…

Technological pedagogical content knowledge TPACK refers to the knowledge set that teachers currently use to further improve the quality of their teaching and assist their students in learning. Several TPACK models have been proposed, either for discussing TPACK's possible composition or its practical applications. Considering that…

This study explores in-service teachers' attitudes and knowledge about a pressing environmental issue, "global climate change" (GCC), and how these may relate to their classroom teaching. In this work, nineteen teachers from Native American communities attended a professional development workshop that focused on enhancing their…

This study assessed Zambian Junior High School pre-service science teachers' understanding of the particulate nature of matter. A sample comprised 30 pre-service science teachers at a teacher training college. Data was collected through a questionnaire adopted from Ozmen and Kenan (2007). Results show that most teachers had correct views on the…

When asking about animals, it is hard to find a person who doesn't recall a beloved pet or share that they've always loved dolphins, snakes, or ladybugs. A study of animals in an early childhood classroom, then, would seem an easy entry into science explorations with children. The article includes reflections on teaching to address the gaps…

Assesses the subject-matter competence in physics of inservice junior secondary science teachers in Hong Kong. Concludes that teachers lack subject-area knowledge. Discusses general implications for educational improvement. Contains 41 references. (DDR)

Explores the problems primary teachers encounter in science and technology and the extent to which these problems are associated with lack of confidence or background knowledge. Findings indicate that there are some ideas which primary teachers come quickly to understand and others that require more extensive professional development. (DDR)
