Pedagogical content knowledge (PCK) has become a useful construct to examine science teacher learning. Yet, researchers conceptualize PCK development in different ways. The purpose of this longitudinal study was to use three analytic lenses to understand the development of three beginning biology teachers' PCK for teaching natural selection…

Professional development has a major role in addressing the skill gaps of teachers. Recently, much effort has been focused on improving teaching practices in Saudi Arabia. Here we aim to determine Saudi teachers professional development needs in the higher educational system. We also focus on skill needs, training programs, factors affecting…

This report describes efforts by a group of science teachers, teacher educators, researchers, and content specialists to conceptualize, develop, and pilot practice-based assessment items designed to measure elementary science teachers' content knowledge for teaching (CKT). The report documents the framework used to specify the content-specific…

The aim of this study was to assess elementary teachers' pedagogical content knowledge (PCK) of and confidence in their ability to support students in enacting the science and engineering practices (SEPs) of the Next Generation Science Standards. Findings from this study were used to inform the planning of a professional development program for…

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…

The implementation of educational reforms requires behavioral changes from the teachers involved. Theories on successful behavioral change prescribe the following conditions: teachers need to possess the necessary knowledge and skills, form strong positive intentions to perform the new behavior, and have a supporting environment for change.…

Action research has been suggested as a useful way to support university faculty to improve teaching and learning. However, there seems to be little knowledge about how faculty (and those who work with them) experience the process of doing action research. In order to explore team members' in-depth experience about what they learned and how they…

We investigated the factorial structure of preservice teachers' academic self-concept with regard to three domains of professional knowledge (content knowledge [CK], pedagogical content knowledge [PCK], and pedagogical/psychological knowledge [PPK]). We also analyzed the relation between preservice teachers' academic self-concept and their…

The purpose of this study was to a) investigate prospective physics teachers' views on their knowledge about new physics concepts introduced in Turkish High School Physics Curricula; b) investigate the sources of their acquired knowledge about these new physics concepts; and c) explore if there were differences in views on knowledge about these…

Middle years' teachers in primary schools are increasingly required to teach curriculum-specific subjects at a depth requiring considerable content and pedagogical knowledge, as well as a detailed understanding of the particular literacy requirements specific to each subject. Science teaching, in the latter years of primary schooling, is…

With the restructuring of the senior secondary education system in Hong Kong in 2009, the senior secondary curriculum was overhauled substantially by the conversion of the two-year Certificate Level and the two-year Advanced Level to a new three-year senior secondary level. This process entails changes to the contents and organization of various…

The purpose of this study was to investigate the problems facing primary teachers in implementing the 5-14 guidelines for science and technology and the extent to which these problems are related to teachers' knowledge and understanding of the subject matter in Scotland. Data collection methods included questionnaires and interviews. A key finding…

This study is an attempt to determine the extent of telecommunications use by secondary school science teachers in the Queens borough of New York City. Science teachers in 39 middle schools and 32 high schools were surveyed in May, 1994, in the following categories of information: access to computers, hardware preference, hardware in use, access…

Two job analyses were conducted to define knowledge domains for newly certified chemistry and physics teachers, respectively, to perform their jobs competently. The results of the job analyses will be used to develop test specifications for the Praxis II Series subject Assessments in Chemistry and Physics. Initial draft domains were prepared for…

The chemical content knowledge of secondary science teachers is seldom measured directly in developed countries as there are practical, ethical and political problems involved that would be likely to be insuperable. In Papua New Guinea (PNG), the author assisted in some of the work involved in the second IEA Science Study (SISS), where the PNG…
