Despite the increased interest in research impact, there is very little empirical evidence that educational research can inform practice directly, and furthermore, a body of literature which suggests that this is, in principle, impossible. This paper reports on a study in which secondary school teachers were given research findings about teaching…

The concept of multiple representations of functions and the ability to make translations among representations are important topics in secondary school mathematics curricula (Moschkovich, Schoenfeld, & Arcavi, 1993; NCTM, 2000). Research related to students in this domain is fruitful, while research related to teachers is underdeveloped. This…

This study reports teachers' insights and challenges after one year of adopting a curricular material designed to move students through carefully engineered, small steps and encourage learners through success and accessible challenges. The analysis of interviews showed that teachers 'followed' the material in different ways, not necessary in-line…

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…

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…

In this study, we considered how four teachers reasoned about proportional situations involving geometry. We used pilot interviews conducted with in-service middle grades teachers around a set of proportional tasks. Analysis relied on a knowledge in pieces lens to uncover the resources that each teacher used in solving the tasks and which…

Currently many children in early childhood education cannot be accommodated in provincial department schools. Consequently, different non-governmental institutions offer Grade R programmes in an attempt to support the DBE. Pre-primary schools that traditionally took responsibility for early childhood education also offer Grade R education. The…

This study examined various influences on special education preservice teachers' appropriation of pedagogical tools for teaching reading to students with high-incidence disabilities using an activity theory framework. Interview, observation, and artifact data were collected on 6 preservice teachers, their reading methods course instructors, field…

New Zealand's early childhood curriculum, "Te Whariki", has two learning outcomes, dispositions and working theories. While a sociocultural perspective of dispositions has received significant attention in research and teaching, "working theories" as a concept has remained somewhat nebulous. This paper describes ways teachers…

Learning how to teach depends on the dynamic inter-relationships among many parts and people; however, research on learning how to teach has typically focused on confined aspects of teacher education (e.g., a specific methods course) over short periods of time (such as one semester). In response, Wideen, Mayer-Smith, and Moon (1998), in their…

This study examines teachers' mathematical understanding of various representations of slope and their knowledge for teaching the concept of slope. Specifically examined in this research are the concept images and concept definitions of slope held by both preservice (N=18) and inservice (N=21) secondary mathematics teachers. Data collected include…

This paper addresses the evidence that secondary school students use to imply that they understand something in mathematics. As part of a larger study, an open-ended questionnaire probing several aspects of metacognitive self-knowledge, was administered to students (N=72) in four schools. Two previously identified types of understanding were…

This paper describes the actions of one secondary school mathematics teacher in establishing a community of mathematical practice within which students acquire not only knowledge and skills, but also the epistemological values of mathematics. Classroom observations over a period of 18 months, together with interview and questionnaire data, are…

Students' conceptual understanding of Newton's third law has been the subject of numerous studies. These studies have often pointed out the importance of addressing the concept of interaction in teaching Newtonian mechanics. In this study, teachers were interviewed in order to examine how they understand interaction and use it in their…
