Problem-solving is of importance in the teaching and learning of mathematics. Nevertheless, a baseline investigation conducted in 2016 revealed that mathematical problem-solving is virtually missing in South African classrooms. In this regard, a two-cycle design-based research project was conducted to develop a professional development (PD)…

Conceptualizing lesson study as an encounter at the boundaries of research and practice, this study examined teacher-academic collaboration for its potential to shape teacher research identity. We report here a case study of a school where the teachers have been able to present their lesson study works in conferences. Documents produced by the…

In this study, I explored how (a) a team-based instructional method rather than a one-teacher-one-classroom, traditional teaching model and (b) an inquiry-based learning approach affected teachers attitudes and self-efficacy for teaching and students attitudes, self-efficacy, engagement, and connections to school. The study was conducted within…

This article reports on the design and findings of the first iteration of a classroom-based design research project which endeavours to design a professional development intervention for teachers' mathematical problem-solving pedagogy. The major outcome of this study is the generation of design principles that can be used by other researchers…

The aim of this article is to shift the notion of 'sites' as places of work peculiar to continuous professional development (CPD) to a theoretical level, independent of, yet intimately connected to, their physical meanings, for example universities and schools. Most CPD initiatives have to contend with at least one of these two sites, in which…

The South African curriculum emphasizes the teaching of problem solving in mathematics. However, little is known about South African teachers' views on the teaching of mathematical problem solving (MPS). The purpose of this study was to establish Grade 9 South African teachers' views, teaching strategies and the support required in their teaching…

Math Teachers' Circles have been spreading since their emergence in 2006. These professional development programs, aimed primarily at middle-level mathematics teachers (grades 5-9), focus on developing teachers' mathematical problem solving skills, in line with the Common Core State Standards-Standards of Mathematical Practice. Yet, to date,…

This paper presents case studies of two teachers at Crescent Girl's School (an all-girls high school in Singapore) who implemented strategies learned through a teacher professional development program called 21st Century Learning Design (21CLD). Policymakers often state requirements for teachers to focus on 21st century (21C) competencies without…

The "No Child Left Behind" legislation requires states to classify schools based on students meeting the state's academic standards. A combination of factors, including scores on state specific tests and nationally normed tests, can result in a school being awarded a low classification or a high classification. In the authors' state,…
