Recent efforts to help teachers improve have centered on teacher evaluation. This qualitative dissertation explored how eight teachers from one middle school described and understood improving their practice Additionally, this study used purposeful developmental sampling to explore how, if at all, participants' way of knowing (meaning their…

One of the goals of secondary science education is to help students develop skills related to scientific inquiry. However, the results of previous studies have shown that students have difficulties in identifying problems, formulating hypotheses, drawing conclusions, and designing experiments. The main objective of this contribution is to indicate…

Although literature emphasizes the value of recursive reflection on problems of practice to facilitate teacher learning and change, few studies investigate teachers' iterative, evolving reflections on problems that emerge in their efforts to change their practice over time. This case study provides an in-depth, longitudinal analysis of one…

Mathematical knowledge for teaching is a complex web of knowledge domains. In this article, we share findings from an 18-month professional development project that aimed to improve middle school mathematics teachers' mathematical knowledge for teaching (MKT) of proportional reasoning by focusing on the critical analysis of mathematical tasks and…
