The purpose of this applied research study with a program evaluation was to answer fundamental questions about the effectiveness of an extended professional development program. The program sought to promote quality mathematics instruction by increasing teachers' knowledge of and supporting the implementation of effective mathematics teaching…

In the 21st century, the demand for proficiency in mathematics has escalated, as it underpins critical thinking, problem-solving, and innovation in various fields. Recognizing the significance of mathematics education, after-school programs have emerged as potent supplementary platforms to enhance students' mathematical skills and achievement.…

Using a multisite cluster-randomized controlled trial design, we evaluated the effect of the first year of a three-year teacher professional development called Cognitively Guided Instruction (CGI) on third -fifth grade students' mathematics achievement. Teachers in the intervention condition participated in nine days of professional development…

Transforming mathematics learning and teaching toward more equitable and effective approaches is critical to student mathematics learning and identity development. This task at-scale in a district takes time, commitment, and mathematics expertise that may not be widespread in the absence of focused professional development. District and regional…

This report derives its findings from Summer/Fall 2023 phone interviews with 22 facilitators and eight administrators following their participation in Math for All during the 2022-23 school year. The findings, summarized below, provide insight into the implementation experience, including challenges, areas of success, and plans for sustaining and…

The goal of this study was to further evaluate the impact of IXL Math on math learning outcomes. Using a quasi-experimental design with matched treatment and control groups, this analysis utilized data from 312 public schools in Mississippi during the 2021-2022 school year. The middle school analysis included 272 schools (136 treatment, 136…

Active Learning is becoming a standard method of delivering instruction in mathematics courses across the country. Researchers, administrators, policy makers, and instructors all need access to valid means of measuring practices used in the classroom. Drawing on the Postsecondary Instructional Practices Survey, the Student Postsecondary…

By examining the effects of a national-scale teacher professional development (PD) program on instructional practices and student mathematics achievement, we contribute to calls for empirical studies investigating the impacts of such programs conducted at scale. The program corresponds well with core critical features of high-quality teacher PD…

Understanding digital supports for early learning is paramount for school readiness and later mathematics learning. We present results from a randomized control trial evaluating a digital app (Measure Up!) and a parent companion app (Super Vision) designed to teach children measurement concepts, a skill that many teachers do not feel comfortable…

Technological advances afford teacher educators, designers, and researchers the opportunity to use videos as an instructional tool to help parents, caregivers, teachers, and other adults support young children's mathematical development. We created five Magic Math Minute videos to highlight examples of young children's mathematical thinking and to…

In this article, we use a two-dimensional assessment to examine the experimental impacts of a mathematics learning trajectory-oriented formative assessment program on student strategies for problems involving multiplication and division. Working from the theory that the development of students' multiplicative reasoning involves improvements in…

The purpose of the study was to investigate whether the districts that received ongoing training and coaching to use the Active Implementation Frameworks improved mathematics outcomes. The Active Implementation Frameworks represent five essential approaches for effective implementation of any evidence-based program or practice. One of the…

The purpose of this evaluation was to examine the impact of i-Ready Personalized Instruction that met Curriculum Associates' recommended usage levels on mathematics achievement, as measured by the Massachusetts Comprehensive Assessment System (MCAS) mathematics assessment. This study compared mathematics achievement growth of students who used…

This paper presents the findings of a 1-year efficacy trial of Maths Counts (MC), an intensive, individualised programme delivered by trained teaching assistants. The programme was delivered 3 times a week over 10 weeks. The sample included 291 Year 3 to Year 6 pupils (age 7 to 11) from 35 primary schools in England. Pupils were individually…

The present study evaluated the effects of a program designed to promote a growth mindset in maths teachers (i.e., the belief that maths ability can improve through experience and learning) to enhance teaching and learning outcomes in their maths classes. The sample was composed of 155 Israeli high-school maths teachers who were randomly assigned…
