This conceptual article explores the use of threshold concepts to help pre-service teachers develop antiracist dispositions. Threshold concepts are "troublesome knowledge" within a discipline that serve as gateways to expanded modes of thinking about subject matter. Grappling with threshold concepts places learners in a liminal space as…

There is a dearth of research on the mechanisms for preservice teachers' development of the pedagogical knowledge necessary for effective use of such technologies. We explored the emergent Technological Pedagogical and Content Knowledge (TPACK) (Niess 2005, 2006, 2007) of a group of secondary mathematics preservice teachers in a methods course as…

One of the core courses in the undergraduate mechanical engineering curriculum has been completely redesigned. In the new numerical methods course, all assignments and learning experiences are built around a video/computer game. Students are given the task of writing computer programs to race a simulated car around a track. In doing so, students…

School science systems tend to emphasize teaching and learning about achievements of science (such as laws and theories) at the expense of providing students with opportunities to develop realistic conceptions about science and science inquiry and expertise they could use to conduct their own science inquiry projects. Among reasons for such an…

This article presents data from a group of secondary pre-service teachers who used vee diagrams to illustrate their conceptual and methodological analyses of a problem, as part of a required mathematics methods course assignment. The individually constructed vee diagrams were analysed in terms of the extent to which they displayed principles and…

Many teachers shy away from teaching their students ethics. Yet American educators are concerned that students are coming into their classes with unacceptable ethical standards. Teaching ethics is important to the intellectual growth of high school seniors, as their departure from home to college or career is imminent. Social studies is a…

Given a sociocultural framework of teaching and learning, argumentation and discourse become central elements of education, particularly in science education because of argumentation's key role in scientific communities. This study documents preservice teachers' perceptions of and aptitudes related to argumentation as they participated in a…

An instructional program was constructed that explored the responses and perceptions of preservice elementary school teachers while finding and using characteristics to construct categories or concepts. The program integrated ideas about teaching thinking skills using computers. HyperCard and videodisk images were used to develop a program so that…
