Rapid advancements in computing have enabled automatic analyses of written texts created in educational settings. The purpose of this symposium is to survey several applications of computerized text analyses used in the research and development of productive learning environments. Four featured research projects have developed or been working on:…

Linked research and development forms the central pillar of the 5-year Wits Maths Connect Secondary Project in South Africa. Our empirical data emphasised the need for teaching that mediates towards mathematics viewed as a network of scientific concepts, and the development of the notion of 'mathematical discourse in instruction' (MDI), as an…

One of the most intransigent problems in mathematics education is the culturally-influenced divide between classroom practice and educational research. This paper describes our explicit attempt to bridge that divide by translating research on instructional practices linked to improving students' mathematics achievement into a brief guide outlining…

Much of the research on the development of professional noticing expertise has focused on prospective teachers. We contend that we must investigate practicing teachers as well, and in particular practicing secondary teachers, because they bring with them years of teaching experience and are situated in unique contexts. Hence we studied the…

The aim of this pilot study was to develop, practice, and evaluate learning environments that are supposed to foster early mathematical reasoning in kindergarten. The participating kindergarten teachers attended a multi-part PD program. The research focused on the development of their teaching skills, and their reasoning practice over one school…

We traced the impact of a sequence of five research-based professional development sessions on a cohort of mathematics teachers' Mathematical Knowledge for Teaching. The sessions focused on task design and implementation as a means of building teachers' pedagogical capacity. Findings revealed that teachers' pedagogical knowledge pertaining to…

Along with the rapid development of technology, videorecording teachers' lessons for professional development or educational research have become commonplace. Although the benefits of the use of videorecording has been well documented, few studies have attended to teachers' affective experiences in relation to videorecording. In this study, we…

This paper explores the role of professional learning community and collegial discussion as important supports for developing teacher expertise in the teaching and learning of mathematics in rural and remote regions of Queensland, Australia. The research reported in this paper is from the first year of a longitudinal research and development…

Many K-12 teachers struggle to meet the needs of diverse learners as school reforms promote new disciplinary literacy requirements. In response, language education scholars have argued that teachers must develop "disciplinary linguistic knowledge" (DLK), or an understanding of language in their content area and an ability to design…

We illustrate an analytic framework for teachers' mathematics discourse in instruction (MDI). MDI is built on three interacting components of a mathematics lesson: a sequence of examples and related tasks; accompanying talk; patterns of interaction. Together these illuminate what is made available to learn. MDI is grounded empirically in…

Research about teacher noticing of students' mathematical thinking has been an important and ongoing strand of research and practice in mathematics education. Our work extends this agenda by working collaboratively with teachers to learn together how to notice students' mathematical strengths. The lens on strengths runs counter to the prevalent…

The aim of this research was to classify the opinions of the disabled participants and educators on Erasmus+ Key Action 2 Project on non-formal learning regarding whether they knew the meaning of non-formal learning, through which non-formal learning activities happening during the Project workshop, and whether this learning had a contribution to…

This paper studies, using quantitative and qualitative data, the effectivity of a professional development approach in which a national summative assessment is used formatively to stimulate 19 teacher teams in Dutch secondary education to improve their data use for instruction and learning. The approach is based on conceptual similarities between…

The following research report documents a professional development that focused on promoting understanding of algebraic learning progressions across vertical teams of elementary and secondary teachers. Analyzing quantitative data from the pre and post MKT assessment and qualitative data from lesson reflections and final course reflections,…

Big Ideas in school mathematics can be seen as overarching concepts that occur in various mathematical topics in a syllabus. Although there has been much interest recently in the understanding of Big Ideas, there is little research done in the assessment of Big Ideas thinking. In this paper, we discuss our research on Big Ideas in School…
