As the number of Multilingual Learner (ML) students attending public schools rises, so does the demand for those who can teach them. Research shows that due to the existence of gaps between different types of knowledge, theory, and practice, the results of teacher preparation programs are often fragmented and do not fully benefit participating…

In this study, we introduce an analytic framework for effective professional development programmes (PDPs) that has been synthesised and derived from the literature. The framework acknowledges that certain design features concerning how to process the content as well as the methods to facilitate teachers' enactment are important but also…

Scholars and practitioners have called for personalized and widely accessible professional development (PD) for teachers. Yet, a long-standing tension between customizing support and increasing access to such support has hindered the scale-up of high-quality PD for individual teachers. This study addresses this challenge by developing a…

This article discusses how mathematics didactics can be inspired by and further developed through responsive pedagogy, understood as feedback directed at self-regulation and self-efficacy, in mathematics teaching. The authors explain the rationale behind an intervention model for improving mathematics teachers' feedback practices. The model is a…

In this article, we describe the experiences of two preservice teachers (PSTs) who served as teaching assistants (TAs) in a secondary mathematics teaching methods course. As TAs, the PSTs approximated practice by being independently responsible for a learning environment and leading discussions with groups of students. Although the PSTs felt…

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…

With online learning becoming a more viable option for teachers to develop their expertise, our report shares one such effort focused on improving the teaching of statistics. We share design principles and learning opportunities in an online course developed specifically to serve as a widescale online professional development opportunity for…

Purpose and Method of Study: The purpose of this study was to compare the effectiveness of two approaches to professional development methodologies implemented in public schools. A quantitative, correlational research design was employed to determine whether the academic success in the core content areas of reading, writing, math and science could…

Thirty primary classroom teachers quantified perceived changes in their practice and knowledge attributed to their school leaders' participation in a six-day course focused on leaders designing and implementing a whole-school reform of mathematics teaching and learning, and the school-based professional learning that followed. The project and…

This report details the importance of professional development and training for graduate student teaching assistants (GTAs) in in the teaching of calculus. Findings from a large, national study in the United States show that GTAs are teaching a large percentage of Calculus I students (either as the primary teacher or as a recitation leader),…

The Fennema-Sherman Mathematics Attitude Scales (FSMAS) are among the most popular instruments used in studies of attitudes toward mathematics. However, the FSMAS has been mainly used among student populations and rarely used with teachers. In the present study, three scales from the FSMAS--"Confidence," "Effectance…

Wide and persistent gaps in math achievement separate English learners from their English-proficient peers. The consequences of these gaps are severe and long lasting. Without a solid foundation in math, students are less likely to access and excel in college preparatory math and science classes in high school. Without high-level math classes in…

What is the evidence that teachers who return to learn more mathematics are better teachers? Over more than a decade we have been involved in six different projects giving teachers the opportunity to reengage with mathematics. We have returned to them to ask the teachers about the long-term impact and to give us examples. The result extends…

Many teacher education programs are criticized for their failure to prepare pre-service teachers to utilize and transfer their knowledge of content and educational principles into authentic classroom teaching. Studies also consistently report that pre-service teachers' ability to identify what is noteworthy about a mathematics classroom situation…

This report presents findings from RAND's evaluation of the Appalachian Renaissance Initiative (ARI) in 17 districts totaling 99 kindergarten-12th grade schools within the Kentucky Valley Educational Cooperative (KVEC). The initiative took place from the 2014-2015 through 2017-2018 academic years. The evaluation examined various aspects of ARI…
