Building Teacher Content Knowledge in Mathematics

SEDL works with educators at all levels to improve teaching and learning in math. We provide professional development, technical assistance, and resources to help educators deepen their content knowledge and adopt research-based practices. In addition, our research and evaluation team conducts studies of math programs to measure their effectiveness and expand our knowledge of how best to teach this core subject.

Success Story

"I LOVE the videos. I’ve never had this explained so clearly. I have been teaching for 11 years, have been leading math PD sessions for 5 years, and this has been a life changer. THANK YOU!!"— Brandy H., Kindergarten Teacher

Common Core State Standards Video Series for Math

A new SEDL video series is helping demystify the Common Core State Standards for mathematics. As states began to implement these standards, education leaders realized the need to provide math teachers with support on content they may not have covered before. In response to state requests for assistance, SEDL’s Southeast Comprehensive Center collaborated with education leaders to develop this video series. Each video explains one math standard. Simple language clarifies the standard's meaning, and examples and illustrations deepen understanding. The short videos, ranging from 5 to 20 minutes, are available online free of charge. SECC states are using the videos in professional development sessions, and the response has been extremely positive, with the video website averaging more than 2,000 visits monthly. Read more

Significant Work

Southeast Comprehensive Center (SECC): The SECC works with the state education agencies of Alabama, Georgia, Mississippi, North Carolina, and South Carolina to build their capacity to support districts and schools in meeting student achievement goals, including achievement in math Work varies by state.

Texas Comprehensive Center (TXCC): The TXCC works with the Texas Education Agency and the state’s 20 regional education service centers to build their capacity to support districts and schools in meeting student achievement goals, including achievement in math.

Everyday Mathematics® Randomized Controlled Trial: SEDL and the University of Wisconsin-Madison are conducting a national, large-scale randomized controlled trial assessing the effectiveness of McGraw-Hill Education’s Everyday Mathematics®, an elementary school math program. The study, which involves more than 40 schools across multiple districts, uses a multisite cluster randomized trial design to examine whether the program affects achievement outcomes for K–5 students over 2 school years and whether those outcomes vary significantly across students, schools, and districts.

Regional Educational Laboratory (REL) Southwest: The REL Southwest assists the states of Arkansas, Louisiana, New Mexico, Oklahoma, and Texas in using data and research evidence to address high-priority education needs in the region. The project addresses early mathematics instruction through the Texas Hispanic STEM (science, technology, engineering, and mathematics) Research Alliance, which examines factors related to improving Hispanic student participation, achievement, and advancement in STEM courses and careers. The REL Southwest also hosts bridge events related to mathematics instruction.

Center for High-Performing Schools: Through the Center for High-Performing Schools, SEDL builds the capacity of district and school leaders and educators to improve teaching and align curriculum, instruction, and assessment to national and state standards.

National Center for Quality Afterschool: This National Center for Quality Afterschool uses web-based technology to provide research-based resources and professional development to help afterschool and expanded learning instructors develop high-quality, balanced programs. The National Center’s free online Afterschool Training Toolkit contains math resources, including sample lessons and videos.

Image of publication cover The Problem with Math Is English

This publication illustrates how students often understand fundamental mathematical concepts at a superficial level. Written to inspire aha moments, the book enables teachers to help students identify and comprehend the nuances and true meaning of math concepts by exploring them through the lenses of language and symbolism.

Image of publication cover SEDL Insights, Vol. 1, No. 4: Teaching Mathematics Conceptually

Mathematics instruction in the United States has historically focused on procedures, facts, and algorithms. Because of that focus, mathematics instruction, in essence, becomes lessons in arithmetic and efficiency. While there are promising changes occurring in mathematics instruction, we still need to help both teachers and students develop a more conceptual understanding of mathematics. This issue of SEDL Insights helps educators shift from helping students memorize rules to facilitating a deeper understanding of mathematics concepts.
