Presents a project used to help students make connections between linear and exponential models and between arithmetic and geometric sequences. (KHR)

Investigates the arithmetic and algebra word problem-solving skills and strategies of future primary and secondary school teachers. Describes the evolution of these skills and strategies from the beginning to the end of teacher education. Indicates that, in the education of preservice primary and secondary school teachers, there is need for an…

Presents an instructional forum in which students and teachers work with researchers to engage in coordinated cycles of planning and implementing instruction and studying forms of students' thinking that emerged in the classroom. Reports on an 8-week teaching and learning study of elementary students' thinking about distribution, including their…

Describes and discusses the language practice of mathematics, science, and English language teachers and learners in a sample of urban and rural, primary, and secondary schools in South Africa. Particular focus is on reception and production of language through code switching, exploratory talk, and discourse specific talk. (Author/VWL)
