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…

Despite the use of literacy coaching to help improve the instructional practices of teachers and increase reading achievement, data of the National Assessment of Education Progress (NAEP) indicate that Florida's students are averaging about 60% below NAEP proficient level. This dissertation reported the results of a nonexperimental study that…

Most studies of test-based promotion policies focus on measuring the effect of retention (being left back) on later student outcomes, and the evidence is fairly mixed. However, test-based promotion policies do not only affect the students who are retained. Presumably, they also affect students and schools as they try to improve reading performance…

There is a strong and politically bipartisan push to increase access to government-funded pre-K. This is based on a premise that free and available pre-K is the surest way to provide the opportunity for all children to succeed in school and life, and that it has predictable and cost-effective positive impacts on children's academic success. The…

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…

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…

Seagrass ecosystems are widespread, valuable, and threatened. We have used this system as a model to teach 3rd-7th grade students about food webs, the interconnectedness of ecosystems, ecosystem services, and the effects of human activity on coastal systems. Our objective was to increase student understanding of seagrass ecosystems and other key…

The Extended Foreign Language (EFL) program is a "school within a school" dual language program in which students are instructed in both English and a language other than English (Spanish or French) with one hour of daily instruction in that language. Most of the schools participating in the program implement the English/Spanish version…

Students who acquire reading comprehension using arts integration will have the opportunity to improve their ability to learn through the following subjects writing, science, language arts, social studies, and mathematics. The problem is economically disadvantaged third-, fourth-, and fifth-grade students did not make adequate yearly gains or pass…

Instructional time is a fundamental educational input, yet we have little causal evidence about the effect of longer school days on student achievement. This paper uses a sharp regression discontinuity design to estimate the effects of lengthening the school day for low-performing schools in Florida by exploiting an administrative cutoff for…

The National Summer Learning Project (NSLP) examined the implementation and effectiveness of voluntary summer learning programs developed by five school districts--Boston, Massachusetts; Dallas, Texas; Duval County, Florida; Pittsburgh, Pennsylvania; and Rochester, New York--and their local community partners. The study spanned three phases. The…

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…

This study aimed to compare the performance of elementary students on the Florida Comprehensive Assessment Test (FCAT) in reading and mathematics between students who received SES services in grades 3-5 and students who qualified for free SES services, but did not receive SES services. Title I funds are set aside annually to pay private providers…

The Wallace Foundation is funding a multiyear demonstration project to determine whether voluntary, district summer learning programs can stem summer learning loss for low-income students. Six districts--Boston, Cincinnati, Dallas, Duval County (Florida), Pittsburgh, and Rochester, New York--were selected for the demonstration project and…
