This study aims to examine the lesson plan development processes and related experiences of prospective teachers, and determine the potential effects their lesson plan development efforts on their perceived TPACK. The research was conducted as part of a 14-week Mathematics Teaching course. During the course, prospective teachers underwent a…

Mathematics teacher educators have suggested preservice mathematics teachers' (PMTs') practices provide evidence of their mathematical knowledge for teaching (MKT). PMTs engage in approximations of practice to rehearse teaching. To explore connections between MKT and PMTs' practices, we operationalized six MKT subdomains in terms of approximations…

Continuous Professional Development (CPD) programme include community of practice, action research, training, and award-bearing. CPDs also include deficit, cascade model, standard-based model, and coaching and mentoring. These CPD programme have been used in acquiring and disseminating new ideas and practices. In Rwanda, towards the effectiveness…

This study explores the extent to which pre-service teachers are able to implement contemporary practices in teaching mathematics during their practicum. The main focus of the study is on the importance of prior engagement of students in learning mathematical concepts. The total population of 150 student teachers from both the Colleges of…

Mathematics teacher educators have suggested that preservice mathematics teachers' (PMTs') practices provide evidence of their Mathematical Knowledge for Teaching (MKT). In an effort to explore connections between MKT and PMTs' practices, we developed a framework that operationalizes Ball et al.'s (2008) six MKT domains in terms of approximations…

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…

We show how we used a national distribution of responses from 416 practicing teachers to items of a test of mathematical knowledge for teaching geometry to estimate changes in knowledge by a group of 11 practicing teachers who participated in a 2-year practice-based professional development programme. To draw a reliable interpretation of the…

This qualitative research presents how a mathematics teacher educator's feedbacks to two lower secondary school mathematics teachers affects their design of hypothetical learning trajectories regarding teaching patterns and their teaching practice. The data comes from a web portal, which was designed as a professional development tool for…

South Africa's esteem is low with regard to current learner achievement in mathematics. Results from international studies, such as TIMMS and SACMEQ, continuously indicate that South African learners perform below international benchmarks in mathematics. Research and evaluation studies assert that teacher practices and poor early mathematics…

This study investigated the relationship between prospective secondary mathematics teachers' perspectives and their mathematical knowledge for teaching in action. Data from two prospective teachers' practice-teachings, one in geometry and one in algebra, their lesson plans and self-reflections were analyzed with Teacher Perspectives and Knowledge…

With international exams (PISA and TIMSS) producing results every three or four years, there is near continual talk of East Asian dominance in mathematics education. Beyond the reporting of scores, some studies have compared mathematics teaching in these countries with U.S. instruction. However, researchers are not (usually) grade school math…

This article presents a case study of how educators in one northeastern school district participated in school-based learning through lesson study (LS). Using a sociocultural perspective on teachers' learning, I compared the participation of educators who were new to lesson study ("LS novices") with those who had more experience with the…

Teams of educators conducted lesson study independently, supported by a resource kit that included mathematical tasks, curriculum materials, lesson videos and plans, and research articles, as well as protocols to support lesson study. The mathematical resources focused on linear measurement interpretation of fractions. This report examines the…

This study investigated how involving in a lesson study process at virtual settings impacted participating teachers' knowledge. The two elementary mathematics teachers, teaching in two public elementary schools at distant cities and meeting occasionally face to face and regularly at virtual settings formed the sample of this study. Neither of the…

Consistent with the theme of this issue, we describe the details of one continuing effort to build knowledge for teacher education. We argue that building a useful knowledge base requires attention to the processes used to generate, record, and vet knowledge. By using 4 features of knowledge-building systems we identified in the introductory…
