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…

This research aims to understand how prospective teachers develop their knowledge about whole-class discussions during a lesson study. Following a qualitative approach, we focus on the work of three prospective mathematics teachers preparing, leading, and reflecting on wholeclass discussions. Data was collected through participant observation with…

This study examined trainee teachers' mathematical knowledge in teaching (MKiT) over their final year in a US Initial Teacher Education (ITE) programme. This paper reports on an exploratory methodological approach taken to use the "Knowledge Quartet" to quantify MKiT through the development of a new protocol to code trainees' teaching of…

Background: Future teachers need to observe, interpret and analyse teaching during the initial teacher education period. The use of videoed teaching and learning in teacher education promotes reflection, and analysing videos of teaching is helpful in learning effective classroom practices that prospective teachers mostly do not have the chance to…

The purpose of this study is to explore the knowledge demands of teacher educators as they teach disciplinary content to preservice elementary teachers, specifically in mathematics, and to understand how such knowledge is different from that used by K-12 teachers. Drawing from a database including teaching and learning artifacts from five…

These Proceedings are a written record of the research presented at the 34th Annual Meeting of the North American Chapter of the International Group for the Psychology of Mathematics Education (PME-NA 2012) held in Kalamazoo, Michigan, November 1-4, 2012. The theme of the conference, "Navigating Transitions along Continuums," focuses on…

In this journal issue, the authors of the focus articles have provided a suite of very stimulating and thoughtful articles. The overarching purpose of this research is to explore the application of principles derived from the view of validity proposed by Kane (2004) to their research on issues related to the measurement of mathematical knowledge…
