While numerous studies have investigated teachers' professional learning through their interaction with resources, the question of how teachers' knowledge evolves at different stages of the instructional process remains underexplored. To address this gap, this article builds on the documentational approach to didactics (DAD) and the theory of…

The research presented in this paper aims to shed light on the complex role of mathematics teacher educators who led courses for prospective mathematics teachers. Theoretically, the research combines the documentational approach to didactics and the meta-didactical transposition frameworks, complementing the study with the analysis of the teacher…

Improving educational practice through reflection is one important focus of teacher professional development approaches. However, such teacher reflection operates under practical classroom constraints that make it happen infrequently, including the reliance on disruptive peer/supervisor observations or recordings. This article describes three…

This brief provides guidance to policymakers and practitioners on the challenges and opportunities of the "dual language immersion" (DLI) model and presents research conducted with teachers and administrators both before and during their first years of implementing new DLI programs in several Indiana school districts. The brief also…

The literature on school improvement is littered with sombre reports of how ICT-mediated innovations have failed to create impact on teaching and learning. Even when evidence-based successes are palpable, they are sporadic and rarely sustainable. Against the backdrop of the litany of such studies, this paper reports the case of a primary school in…

Professional learning community (PLC) is a current "buzz" term in business and educational contexts, seemingly referring to anything from decision making committees to regular meeting groups or collegial learning teams. This paper explores the concept of a PLC within three significantly innovative schools, based on an examination of the…

We observe teachers in professional development courses about energy constructing mechanistic accounts of energy transformations. We analyze a case in which teachers investigating adiabatic compression develop a model of the transformation of kinetic energy to thermal energy. Among their ideas is the idea that thermal energy is generated as a…

"RTI in Middle School Classrooms" provides practical, research-based instructional techniques and interventions--geared especially to middle school teachers and administrators--that target and address specific needs of individual students. Response to intervention allows educators to assess and meet the needs of struggling students…
