In this article, we outline the findings of a Canadian survey study (N = 302) that focused on the extent of computer algebra systems (CAS)-based technology use in postsecondary mathematics instruction. Results suggest that a considerable number of Canadian mathematicians use CAS in research and teaching. CAS use in research was found to be the…

This study is based on our belief that mathematics should be challenging in any classroom and that mathematical challenge is among the central factors that determine the quality of mathematics lessons. Choosing challenging mathematical problem for the students is central in teachers' work while their conception of mathematical challenge can…

New science curricula in Ontario position science, technology, society, and environment (STSE) objectives at the fore of all science courses. A professional learning community (PLC) consisting of 24 elementary teachers and a facilitation team was established to assist teachers in meeting the challenges of STSE education. Specifically, we examine…

Analysis of views from a select group of Kenyan science teachers regarding the effect of student learning experiences on their teaching after implementing a contextualized science unit revealed that the teachers' (a) literal interpretation and adherence to the official curriculum conflicted with the students' desires to understand…

What is the evidence that teachers who return to learn more mathematics are better teachers? Over more than a decade we have been involved in six different projects giving teachers the opportunity to reengage with mathematics. We have returned to them to ask the teachers about the long-term impact and to give us examples. The result extends…

We propose that what teachers can say or write about their views of mathematics and about a range of pedagogic strategies and didactic tactics that they use is of minor importance compared to what comes to mind moment by moment when they are planning or leading a lesson. Beginning with a quote from a teacher that provoked a focus on the role and…

Among new technologies, interactive whiteboards (IWBs) particularly seem to engage students and offer entertainment value that may make them highly beneficial for learning. This study examined 10 Grade 6 teachers' initial experiences and uses of IWBs for teaching science. Through interviews, classroom visits, and field notes, the outcomes…

Reports on the third of a line of investigations that examine pre-service teachers' conceptions of nature of science (NOS) and the translation of those conceptions into classroom practice. Delineates the effectiveness of an intervention designed to facilitate pre-service teachers' inclusion of NOS in their classroom teaching. (Author/MM)

Explores some of the complexity of the influences that shape teacher practice in relation to teachers' theories, knowledge, and beliefs about the teaching of mathematics. Focuses on the relationships that exist between teachers' espoused theories and their theories-in-use. (Author/MM)
