We discuss the evolution of an instructional unit for supporting prospective elementary and middle grades' teachers' conceptions of fractions as measures. We first studied prospective teachers' conceptions of fractions using a task-based written assessment with discrete, linear, and circle representations. We designed an instructional unit that…

The subject of research methods is often unknown, foreboding, and unappealing to undergraduate communication majors. Thus, in the research methods course, two ways to overcome such issues and achieve learning are by: (1) making the unfamiliar more familiar and accessible; and (2) placing abstract knowledge in its useful real-world context. Making…

One proven strategy to help students make sense of abstract concepts is to sequence instruction so students have exploratory opportunities to investigate science before being introduced to new science explanations (Abraham and Renner 1986; Renner, Abraham, and Birnie 1988). To help physical science teachers make sense of how to effectively…

This article describes a 3-week intensive molecular biology methods course based upon fluorescent proteins, which is successfully taught at the McGill University to advanced undergraduates and graduates in physics, chemical engineering, biomedical engineering, and medicine. No previous knowledge of biological terminology or methods is expected, so…

Developing deep knowledge and understanding of mathematics is a lifelong process, and building the foundation for teachers' development must begin in preservice preparation and continue throughout one's professional life. While teaching mathematics content courses and methods courses, the authors have found that preservice elementary school…

This theoretical paper proposes a way to extend the partitive and measurement interpretations of whole number division to fractional contexts focusing on the issue of units. We define the unit-changing and unit-keeping interpretations for division and suggest a stronger and earlier focus on the concept of units in courses for prospective…

In response to the claim that students who have received an undergraduate degree in education lack adequate preparation for postgraduate study, the designers of a masters course in research methods set an assignment at the first meeting which asked practising teachers to match Goffman's dramaturgical concepts to observation of behaviour in public.…

Reflection is widely embraced in teacher education as a necessary process in becoming a good teacher. While there is broad acceptance of this idea, the nature of reflection has been challenged, particularly by those seeking reflection that is socially situated and critical, implicating teaching in its broader social context. This paper examines…

Slow motion animation ("slowmation") is a new teaching approach that uses a simple animation process to engage learners in creating their own comprehensive animations of science concepts. In this paper, preservice elementary teachers used slowmation, a form of stop-motion animation, to make models of science concepts and take digital…

Describes and evaluates an elementary science methods course in which the nature of science and scientific inquiry are embedded and explicitly taught. As a result of the course, incoming conceptions of science as primarily a body of knowledge changed to a more appropriate, blended view of science as a body of knowledge generated through the active…

The constructivist perspective, which holds that children's learning of subject matter is an interaction between what they are taught and what they bring to a learning situation, could be used to improve mathematics teacher education. (PK)

The use of constructivism and its various manifestations in education has been a topic of much interest in recent years. Inquiry into this theoretical framework has resulted in teacher educators' attempts to help their teacher candidates apply constructivist pedagogy in university classrooms, field experiences and student teaching at two US…

This book addresses the question: What is being done to educate current and future teachers of science so that they will be successful in promoting meaningful learning of science? The authors of the 15 chapters in this yearbook explore various dimensions of the preparation and enhancement of teachers of science, including practical and…
