Research indicates that investigating phenomena, rather than reproducing facts, should be a core experience in the education of prospective mathematics teachers. Corresponding with its centrality to quality teacher education, there are multiple existing methodologies for analyzing the effects of investigation tasks on teachers' mathematical…

Teacher professional learning communities (PLCs) are a valuable tool that increase teacher collaboration to enhance student learning. These adult learning environments are dynamic in that they are places where adults are able to work within a community of practice (CoP) to address work-related challenges and lend support in semi-structured…

This study piloted a reading comprehension instruction professional development intervention for teachers of upper elementary grade students (Unlocking Understanding), exploring the relative effects of two versions of the intervention that varied the degree of lesson scripting. Results indicated a statistically significant difference between the…

In this study we introduce "lesson play experience" (LPE) for implementation as professional development for in-service teachers. LPE is an extension of the "lesson play" notion, which refers to a script for an imagined lesson, written by a teacher, presented as dialogue of teacher-student(s) interaction. In mathematics teacher…

We show how we used a national distribution of responses from 416 practicing teachers to items of a test of mathematical knowledge for teaching geometry to estimate changes in knowledge by a group of 11 practicing teachers who participated in a 2-year practice-based professional development programme. To draw a reliable interpretation of the…

Experts have heralded domain-specific play-based curricula coupled with regular coaching and training as our "strongest hope" for improving instructional quality in large-scale public preschool programs. Yet, details from different evaluations of the strongest hope model are not systematically compiled, making it difficult to identify…

Though the future cannot be accurately predicted, it is possible to envisage a number of probable developments which can promote thinking about the future and so promote a more informed stance about what should or should not be done. Studies in technology and society have claimed that the use of a type of forecasting using plausible but imaginary…

There is growing interest in the field of education for leveraging emerging digital technologies to support teachers' learning in online or blended settings. This paper builds on Clarke and Hollingsworth's (2002) "Interconnected Model of Professional Growth" by investigating an alternative instantiation of "professional…

This mixed-methods study investigated elementary teachers' perceptions of curriculum-based readers theatre (CBRT) as a relevant approach for teaching English language learners (ELLs). I collected quantitative survey data from teachers who worked at the school with the largest population of ELLs in a large Florida school district. The survey…
