We examine the role of tasks that have the intended effect of teachers re-conceiving the mathematics they teach as comprising a coherent body of meaningful ideas. We ground our discussion in ideas of trigonometry and modular functions and draw from a professional development research project to illustrate our approach. In this project, many…

Although the use of learning technology has become increasingly prominent in schools, significant changes in teaching strategies have not kept pace. Lack of quality professional development and inadequate teacher preparation are often cited for this situation. This case study explores the use of the student teaching experience as an avenue for…

National and international reform documents have forged blueprints for advancing science education. Coursework for preservice teachers needs to correspond to these documents by providing learning experiences that develop preservice teachers' capabilities to plan and implement reform measures. Using a pretest-posttest design, responses from 59…

This study examined changes in personal science teaching self-efficacy (PSTE), outcome expectancy (STOE), and science conceptual understanding and relationships among these in preservice teachers. Seventy preservice teachers enrolled in science teaching methods courses participated in this study. PSTE, STOE, and science conceptual understanding…

Explicit instruction of the nature of science (NOS) may be problematic if the NOS is portrayed as either a solely a cognitive or discursive endeavor, overlooking other aspects of epistemology, such as aesthetic ways of knowing. Here the aesthetic stance refers to individual's responses during reading as they create links between the text and their…

This article describes an innovative approach to developing preservice elementary science teachers' classroom confidence and skills. Based on lesson study approaches, preservice candidates designed and taught integrated science-mathematics lessons during the semester before their student teaching. Working in teams, candidates designed and taught a…

This study investigated whether or not an increase in secondary science teacher knowledge about evolution and the nature of science gained from completing a graduate-level evolution course was associated with greater preference for the teaching of evolution in schools. Forty-four precertified secondary biology teachers participated in a 14-week…

Mentoring is often an important component of alternative certification programs, yet little is known about what novices learn about science teaching through mentoring relationships. This study investigated the advice given by two mentor science teachers to their proteges. Findings indicate that mentors gave more advice related to general…

Middle grades science teachers need professional support in practice as they implement new inquiry-based science. Professional development schools can provide this bottom-up support through connecting preservice and inservice teacher education programs in classroom practice. In this study, coteaching arrangements with secondary science education…

Since there is an increasing recognition to address the need to move practicing teachers to a higher standard of practice, mentoring or coaching has been receiving increasing attention. A variety of tools has been developed to make these relationships more effective. Work within a recent mentor project indicated current tools were not detailed…

This study explores the extent to which an activity used in an elementary science methods course affected the preservice teachers' content knowledge, attitudes, and self-efficacy. The participants were 172 students enrolled in five sections of elementary science methods. Students participated in a 9-week investigation on life cycles using…

This paper describes a three-level framework (technical, domain, and generic) which enables some generalisability across mathematics topics for effective teacher-education (TE) task design. It argues that TE tasks which encompass these levels increase preservice and inservice teachers' interest because they transcend the particular mathematical…

In this article we introduce a usage-goal framework within which task design can be guided and analyzed. We tell a tale of one task, the Pentomino Problem, and its evolution through predictive analysis, trial, reflective analysis, and adjustment. In describing several iterations of the task implementation, we focus on mathematical affordances…

Our work is in keeping with the general framework of didactical research in France, where we both studied, and now teach. This paper describes a model training session designed for in-service mathematics teachers, whose purpose is to guide them in their understanding of the relationship between students' tasks and activities in secondary school…

Mathematical tasks, centered on arithmetic word problems, are discussed as the basis of an approach to facilitate preservice elementary teachers' development of mathematical knowledge for teaching arithmetic operations. The approach consists of three groups of tasks that allow students to reflect on their initial knowledge, explore arithmetic word…
