This study examined the variations between providing secondary-school teachers with collaborative professional development (PD) and traditional PD. Although the U.S. local and federal governments spend billions of dollars on teacher PDs each year, there is still a debate on the effectiveness of those trainings. Research suggests that the most…

This study investigates, and further develops, a framework for analyzing technological knowledge emanating from school design projects; a framework that has the potential to be used as a tool for teachers when choosing and planning design projects. The study also intends to answer the research question: What technological knowledge, associated to…

Many studies have reported on the influence of teachers' conceptions of variability on different aspects of their professional knowledge for teaching statistics and their classroom practices. However, research on these kind of conceptions is still scarce, particularly in Latin American countries like Venezuela. In an effort to help fill this gap,…

In this chapter we envision the science classroom as an authentic scientific community. In this vision, student ideas can influence the trajectory of scientific investigation. Teachers serve as experts and guides, but they also can learn alongside their students. To do this, they need to listen to the students and be able to build on students'…

We show how we used a national distribution of responses from 416 practicing teachers to items of a test of mathematical knowledge for teaching geometry to estimate changes in knowledge by a group of 11 practicing teachers who participated in a 2-year practice-based professional development programme. To draw a reliable interpretation of the…

This article explores teachers' knowledge and views on the role of learners' socio-cultural background when teaching Natural Sciences to Grade 9 learners at three South African township schools. Within a socio-cultural framework, the research investigated how teachers accommodate learners' cultural norms and values, religion and beliefs,…

This study was intended to enhance the limited research on the knowledge and confidence of special education teachers in public education regarding transition services and the quality of transition plans they develop. The key variables examined in this study are knowledge, confidence, and the quality of student transition plans. The sample…

The authors examined the characterization of mathematical knowledge of teachers using educative curriculum materials. In particular, they investigated knowledge of change and rate of change (in the context of algebra and functions) of 12 teachers with differing levels of experience. Participants used a same set of curriculum materials that embed…

This study compared conversations among groups of teachers of high school geometry that had been elicited by a representation of instruction (either a video or an animation) and facilitated with an open-ended agenda. All artifacts used represented instruction scenarios that departed from what, according to prior work, had been hypothesized as…

In this essay, I offer a response to Stemhagen, Reich, and Muth's (see EJ1089246) delineation of disciplined judgment. I draw from my latest obsession with epistemologies of ignorance to complicate their focus on disciplinarity with questions over how non-knowledge gets framed and created. I use Suniti Sharma's seven-year study to highlight the…

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…

Inquiry is essentially a process in which research questions are asked and an attempt is made to find the answers. However, the formulation of operational research questions of the sort used in authentic scientific inquiry is not a trivial task. Here, we set out to explore the possible influence of separating the research question from the…

The authors describe ways in which a history of mathematics course can help prospective teachers of mathematics develop knowledge they will need for teaching. The types of knowledge include content knowledge of mathematics, knowledge of mathematics for teaching, and pedagogical knowledge.

One chronic challenge facing professional development providers is the need to convene and support groups of role-alike K-12 teachers who require similar kinds of discipline-and grade-level-specific training. Online courses have become an increasingly common way to meet this challenge. This article reports on a randomized control trial that tested…

South African schools have been confronted with educational reform since the mid-nineties and the process is still continuing. The concomitant changes put a very high demand on physical sciences teachers and also have an impact on teacher behaviour. The purpose of this study was to probe whether teachers could be considered equipped to teach the…
