Over the past several decades, science education reforms have called for students to develop appropriate views of the nature of science and have a comprehensive understanding of subject matter. Additionally, education research has demonstrated that teachers must have appropriate views of the nature of science and strong content knowledge as…

This study asked 241 primary children and their 13 teachers in the Canton of Berne, Switzerland, to identify 136 local plant and animal species, which were shown to them as pictures. Children's age, gender, and experiences with nature were recorded to test for associations with species knowledge. Teachers identified 52% of the plants and 61% of…

In our investigation of university students' knowledge about real numbers in relation to computer algebra systems (CAS) and how it could be developed in view of their future activity as teachers, we used a computer algorithm as a case to explore the relationship between CAS and the knowledge of real numbers as decimal representations. Our work was…

In this paper we probe prospective mathematics teachers' thinking as displayed in their solutions to a geometry content knowledge-based task. Geometry content knowledge is examined in terms of connections made by these prospective teachers between the geometric configurations and the geometric principles established through visualization and…

This study reports on the level of trigonometry Subject Matter Knowledge (SMK) of third and final-year pre-service second-level mathematics teachers () at an Irish third-level institution. The aim of the study was to determine if this sample of prospective teachers has an appropriate level of SMK to teach second-level trigonometric concepts. The…

The aim of this qualitative case study is to investigate prospective mathematics teachers' subject matter knowledge of the underlying concepts of standard and nonstandard algorithms used to solve the problems with whole numbers. Twenty three prospective mathematics teachers enrolled in the Elementary Mathematics Education Program of one of the…

This qualitative case study investigated teachers' Technological Pedagogical Content Knowledge (TPACK) for teaching high school geometry in Turkey. Four TPACK components and their corresponding five TPACK level descriptions were used for examining three geometry teachers' TPACK through their technological instructional plans, microteaching…

Informed by literature on developing pedagogical content knowledge (PCK) through teacher collaboration, this study aims to investigate the trajectory of PCK development among business English teachers through module team collaboration in Chinese context. Drawing upon multiple sources of data including observation, semi-structured interview, and…

Teaching chemical bonding using the octet rule as an explanatory principle is problematic in many ways. The aim of this case study is to understand the learning and teaching of chemical bonding using a research-informed teaching model in which chemical bonding is introduced as an electrostatic phenomenon. The study posed two main questions: (i)…

This case study research is informed by Vygotsky's view that talk is essential to organise our thoughts and extend our thinking and that, as Barnes suggested, the teacher needs to use the social situation effectively in the classroom to promote talk for learning. This article focuses on pedagogy and teachers' understandings of how talk works in…

In this paper, we discuss how a university lecturer (pseudonym: James) drew on his technological pedagogical and content knowledge (TPACK) when planning to integrate technology in teaching. The main purpose of the study was to use real-life planning observations to understand James's TPACK. The data were obtained through think-aloud sessions in…

Asia is the world's largest continent, both in terms of land mass and human population; yet, many of the schools in the United States still embrace a Eurocentric curriculum, and resultantly, U.S. citizens remain largely ignorant about topics pertaining to Asian nations including their geography, histories, politics, economics, religions, and…

This study investigates the pedagogical skills and knowledge of three tertiary-level mathematics support tutors in a large group classroom setting. This is achieved through the use of video analysis and a theoretical framework comprising Rowland's Knowledge Quartet and general pedagogical knowledge. The study reports on the findings in relation to…

The purpose of this study was to explain middle school teachers' decisions for planning a science unit of instruction (reflection on action) and their decisions when enacting this planned unit (reflection in action) using the new teacher professional knowledge and skill (TPK&S) model as a guiding framework. In addition, this study specifically…

This article reports on a study that investigated the extent to which 57 Grade 6 students at a particular school have misconceptions regarding equality, with the equal sign as focus. It also investigated this school's three Grade 5 and 6 teachers' mathematical knowledge for teaching regarding equality, again focusing on the equal sign. The…
