This paper is concerned with the process of how subject and pedagogic knowledge emerge through teachers' learning in science. It suggests that problematizing subject knowledge through direct experience of learning in science, particularly in those areas that are known to be difficult, constitutes a productive way of turning a deficit model of…

This mixed method case study provides insights about how the professional development of middle school teachers is facilitated through their participation in content-focused online communities of practice. A key finding from this research reveals that the online community provided teachers with enhanced opportunities to share ideas, to discuss…

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…

America's urban public schools and their students are in dire need of a durable and committed corps of teachers, teachers who are willing to stay in education long enough to make a difference in the conditions of those schools, and most importantly, in student achievement. Many traditional teacher education programs critique alternative programs…

For many years, education researchers excited by the potential for digital technologies to transform mathematics teaching and learning have predicted that these technologies would become rapidly integrated into every level of education. However, recent international research shows that technology still plays a marginal role in mathematics…

More children and adolescents who have chronic illnesses are being included in regular education classrooms today than ever before. However, teachers may not feel confident about being able to meet these children's educational, social, or emotional needs in the classroom. School psychologists are able to assess children's functioning in these…

This article reports on a case study of Instant Messaging (IM) in a context of high-school virtual schooling. Data collection relied on interviews conducted with 20 participants in a context of high-school web-based instruction in Newfoundland and Labrador, Canada. The participants included e-teachers as well as other distance education personnel.…

This paper reports on a case study of a "lead literacy teacher" initiative in one Canadian province. This initiative is related to a ''minority world'' trend in teacher in-service that seeks to develop "experts" in a field with the intent that such experts can help other teachers to raise student achievement for the betterment…

The goals of the Head Start on Learning Science project include increasing Head Start staff and parents' awareness of the value of science; introducing teachers to integrated, inquiry-based science; and providing follow-up support to teachers and parents. This document is an evaluation report of the program that contains planning, formative, and…

In this study I examined 19 preservice secondary mathematics teachers' solution processes to word problems for which the subtraction or addition of the two given numbers yields 1 more or 1 less than the correct solution. Among the aspects of their solution processes that were examined are: the modeling strategies, the type of errors, and the…

This essay presents a discussion of how the tools and resources of open source education may demonstrably improve education quality. The main tenet of open education is to make educational assets freely available to the public. This is becoming easier and less expensive as network and multimedia technology evolves. Obstacles may stand in the way…

This booklet is an addendum to the conference proceedings of the 20th annual meeting of the International Group for the Psychology of Mathematics Education (PME 20). It contains three reactions to the research forum: (1) "Mathematizing: The 'Real' Need for Representational Fluency" (R. Lesh); (2) "Mathematics Teacher Development: An Alternative…

Tutoring is not a new idea nor a new practice in the world of teacher education. However, our understanding of how to better use tutoring as a vehicle for applying authentic knowledge and pedagogy is expanding rapidly. The purpose of this article is twofold. First, it provides an overview and rationale of a tutoring-field experience in which we…

Articles include: (1) "Watching Ourselves Learn" (Annette Thorson); (2) "Search Smarter!" (Kimberly S. Roempler); (3) "Teacher Education Materials Project" (Joan…

This paper provides a critical analysis of a professional development model that proposes to improve inquiry science instruction by addressing two components of teacher knowledge: pedagogy and science content. Although this represents an improvement over professional development models that focus on a single area of teacher knowledge, this paper…
