Lesson study, especially when conducted with support from targeted resources, is often identified as a potentially effective means to support teacher learning. In this study, 80 school-based teams of educators, representing 80 classrooms of third- or fourth-grade students in the US, were randomly assigned to one of four conditions: lesson study…

Early mathematics achievement is a strong predictor of later mathematics achievement, and student competence in fractions and division may be the strongest predictor of success in secondary-level algebra. We used a multisite cluster-randomized trial to estimate the impact of a mathematics teacher professional development (PD) program on student…

"Math Expressions" is a curriculum for students in prekindergarten through sixth grade that aims to build students' conceptual understanding of mathematics and to develop fluency in mathematical problem solving and computation. The curriculum encourages student learning of mathematics through real-world situations, visual supports such…

Children in Florida who will be 4 years old on or before September 1st of the school year are eligible to attend a Voluntary Prekindergarten Education Program (VPK), provided by either the public school districts or other private providers, regardless of family income. There are several different VPK programs, including Head Start, Title I, and…

The Board on Science Education and the Board on Mathematical Sciences and Analytics of the National Academies of Sciences, Engineering, and Medicine convened the Workshop on Increasing Student Success in Developmental Mathematics on March 18-19, 2019. The Workshop explored how to best support all students in postsecondary mathematics, with…

Billions of dollars are spent every year on teacher professional development (PD) programs (Fermanich, 2002; Odden et al., 2002; TNTP, 2015; U.S. Department of Education, 2014). The few rigorous evaluations of PD programs that have been done usually report a null effect on student achievement, leading many scholars to conclude that teacher PD…

This report examines the implementation of Summer 305, an enhanced summer program which operated from June 20 through July 25, 2023 at 111 sites in Miami-Dade County Public Schools (M-DCPS). Twenty-two programs were offered to accelerate learning recovery, develop foundational skills, and address social and emotional needs. Enrolled students…

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…

This report examines the implementation of Summer 305, an enhanced summer program that operated from June 14 through August 5 during the summer of 2022 at 113 sites in Miami-Dade County Public Schools (M-DCPS). Twenty program offerings were provided to accelerate learning recovery, develop foundational skills, and address social and emotional…

Contemporary state math standards emphasize that students must demonstrate an understanding of the mathematical ideas underlying the computations that have typically been the core of the elementary school math curriculum. The standards have put an increased emphasis on the study of fractions in upper elementary grades, which are the years during…

Teacher professional development is considered as one of the key factors for improving the quality of teaching and learning. This study aimed to investigate teachers' participation in technology professional development across the states between 2005 and 2015. The present study explored the differences in students' mathematics achievement scores…

Although nearly half of community college students require some type of remediation, less than one-third of the students who start in developmental education graduate within eight years (Park, Tandberg, Hu, & Hankerson, 2016). As such, there is great uncertainty regarding the effectiveness of developmental education (Ari et al., 2016; Bailey…

Enhancing all students' academic performance continues to be a national priority, and although achievement gains have been made overtime, shortfalls in mathematics learning for students with disabilities (SWD) remain. Research reveals that a substantial portion of the variability in students' mathematics achievement gains is due to the teacher. To…

Mathematics teacher professional-development (PD) programs based on Cognitively Guided Instruction (CGI) have been developed and implemented with tens of thousands of elementary mathematics teachers worldwide since the 1980s. Starting with a focus on addition and subtraction on whole numbers in the first CGI PD program, the content of these…

This report examines the implementation of Summer 305, an enhanced summer program which operated from June 24 through July 26 during the summer of 2024 at 103 sites in Miami-Dade County Public Schools. Twenty-two program offerings were provided to accelerate learning recovery, develop foundational skills, and address social and emotional needs.…
