In Ireland, Initial Teacher Education [ITE] standards require all teachers to possess an adequate level of numeracy themselves in order to teach for numeracy learning across the school curriculum. This paper reports on a study that investigated 204 pre-service post-primary teachers' numeracy capabilities. Analysis of questionnaire data from…

This study examined a cohort of middle school pre-service mathematics teachers' understanding of the rate of change as they engaged in a model development sequence. By adopting a design-based research perspective, a model development sequence on the concept of rate of change has been designed and implemented as part of a mathematical modeling…

This study examined the effect of a professional development training programme on 20 second-year preservice mathematics teachers' knowledge in foundational mathematical concepts at a rural university in South Africa. The training programme aimed to enhance preservice teachers' mathematical knowledge for teaching. An embedded mixed-methods case…

Probability signifies a mainstream strand in mathematics curricula. Nonetheless, many curricular documents prepared for teachers might not offer enough support. In such a situation, a further reflection on teachers' professional knowledge for teaching probability is demanded; especially, from the perspective of probabilistic reasoning (PoPR) that…

This study examines future secondary physics teachers' knowledge related to the teaching of sound waves, and specifically the topics of sound level and sound intensity. The data is comprised of future teachers' responses to a task in which they had to compose a script for an imaginary dialogue between a teacher and a group of students and to…

This article focuses on student teachers' professional development and explores how the students connect theory and practice in these processes. Data consist of 17 talks during weekly seminars with 15 preschool student teachers and a group of researchers both at campus and at the practicum placements during their first term. Initially, the…

As a component of a course on geometry for preservice elementary teachers (PSTs), we derive area formulas for a variety of polygons including triangles, quadrilaterals, and both regular and irregular shapes whose areas can be measured empirically using decomposition. Decomposing a circle to justify why its area can be measured using the standard…

Deciphering teachers' paths to their disciplinary professional identities can make important elements of their tacit knowledge explicit and available to their students.

In order to reach students who can efficiently use intended scientific understandings, it is important to have science teachers without conceptual difficulties. The aim of present research is to enhance pre-service science teachers' conceptual understanding about boiling by dialogic teaching. The sample consisted of forty-three pre-service science…

Much research has been conducted regarding student alternative conceptions in chemistry, and a significant amount of work has focused on the areas of chemical equilibrium and reaction rates. Less research has focused on teachers' alternative conceptions in these areas, and most of this work has studied the conceptions of pre-service and novice…

Within teacher education, there is ongoing debate about the nature and extent of the propositional and conceptual knowledge that teachers need. In this paper we interrogate the learning tasks detailed in six learning modules offered in a formal qualification for South African Foundation Phase (grade R-3) teachers. Our purpose is to analyse to what…

Amid the implementation of new curriculum standard regarding statistics and new recommendations for preservice secondary mathematics teachers (PSMTs) to teach statistics, there is a need to examine the current state of PSMTs' knowledge of the statistical content they will be expected to teach. This study reports on the statistical knowledge of 217…

The role of teacher education is to initiate purposeful conversation regarding specific content, to provide the scaffold for which preservice teachers can begin to understand the subject matter for the purpose of teaching, and to acknowledge gaps in their conceptual knowledge (Grossman and Shoenfeld with Lee 2005). Teacher candidates may enter…

The concept of multiple representations of functions and the ability to make translations among representations are important topics in secondary school mathematics curricula (Moschkovich, Schoenfeld, & Arcavi, 1993; NCTM, 2000). Research related to students in this domain is fruitful, while research related to teachers is underdeveloped. This…
