This paper draws from a broad study that explored mathematics teachers' engagement with textbooks within the Lesson Study context. In the current paper, we report on teachers' use of mathematics textbook activities to inform their instructional decisions during collaborative lesson planning of numeric and geometric patterns. The study took place…

When employees expect evaluation and performance incentives will continue (or begin) in the future, the potential future rewards create an incentive to invest in relevant skills today. Because skills benefit job performance, the effects of evaluation can persist after the rewards end or even anticipate the start of rewards. I provide empirical…

Thirty-eight fourth-through sixth-grade teachers (28 female; 10 male) in urban schools in Chile were interviewed to determine how teachers' preparation to teach writing and their knowledge of how to do so acted as facilitators and/or barriers to classroom writing instruction. Teachers overwhelmingly identified their preservice preparation as a…

This study explored the mathematics teacher identity (MTI) of three purposefully selected grade 6 non-specialist primary school mathematics teachers. The participants' subject matter knowledge and didactical skills were explored by means of semi-structured interviews, lesson observations, and document analysis of lesson plans. The data were…

Mathematical knowledge for teaching (MKT) is a professional knowledge crucial for effective mathematics instruction, encompassing both content knowledge (CK) and pedagogical content knowledge (PCK). The purpose of this study is to investigate the hierarchical structure of PCK for fractions by seeking further evidence for the PCK-Fractions…

This study aims to investigate elementary school mathematics teachers' (teaching grades 5-8) questioning skills in class. It also includes observation of the questioning skills of two elementary school mathematics teachers teaching eighth grade. This mixed-methods research study follows an explanatory sequential design. Initially, quantitative…

Intervention research indicates that historical inquiry curricula call for different tasks, materials, and methods of teaching compared to those focused solely on content. Inquiry curricula require teachers to shift from the methods, materials, and assessments to which they are accustomed. As a result, despite intervention research efforts that…
