Teacher professional learning occurs across various contexts. Previous studies on teacher learning and changes in practice have focused on either classroom contexts or learning communities outside of school, but have rarely investigated teacher learning across multiple contexts. Investigating teacher learning across the double contexts of…

Although the Common Core State Standards call on parents to support professional educators' efforts for improving student academic achievement, we have yet to examine how to best support parents in achieving this goal. The present study addresses this need by examining a five-month mathematics intervention which aimed to increase awareness of the…

In this paper, we describe teachers' learning of an instructional practice related to launching a cognitively demanding task. Using a multi-case study design, we analyze eight teachers' participation in a rehearsal of the instructional practice in professional development and the ways these teachers enacted this practice in their classroom…

Considerable discrepancies between the mean and median often occur in data sets that are skewed left, skewed right, or have other unusual features. In such cases, it is important to analyze the data and context carefully to decide how best to describe centers of distributions. The importance of this type of statistical thinking is acknowledged in…

This study examines elementary- and middle-grade teachers' understanding of the mathematical learning progression as they participated in a 6-month professional learning project. Teachers participated in a professional development project that consisted of a 1-week summer content-focused institute with school-based follow-up Lesson Study cycles in…

This study examines the impact of Learning and Teaching Linear Functions (LTLF) professional development materials on teachers' mathematics understanding and teaching practices, as well as students' resulting algebra proficiency, learning, and achievement. Learning and Teaching Linear Functions are modular, video-based professional development…

This study examined ways in which students make use of a graphing calculator and how use relates to comfort and understanding with mathematical symbols. Analysis involved examining students' words and actions in problem solving to identify evidence of algebraic insight. Findings suggest that some symbols and symbolic structures had strong…

Many teachers use the Internet and other electronic and web-based resources to engage students in meaningful assignments for independent learning, greater ownership of learning and better preparation for college and careers. The technology practices should align with the new college- and career-readiness standards (CCRS). They also should enhance…

The purpose of the study was to examine how teachers enhance their knowledge of rational numbers focused on modeling problem tasks using multiple representations. The professional development summer institute and the follow-up Lesson Study (Lewis, 2002) throughout the academic year focused on engaging teachers in rational numbers and proportional…

The research literature concerning traditionally aged college mathematics students' who require remediation, in beginning Algebra topics, states that these students lack confidence in their mathematical skills, have experienced failure and frustration in the past, have low self confidence issues with respect to mathematics and often lack…

"The Electric Company" ("TEC") television show won the hearts of children because it made learning fun. Thirty years later, the iconic show has returned with the goal of not only teaching literacy, but also numeracy (the ability to work with and understand numbers) and mathematics vocabulary in a fun, entertaining, and engaging…
