This study followed a cohort of former ELLs for two years after they exited the EL program. The exit school year for this cohort was between August 2022 and June 2023. We compared their academic achievement in English language arts (ELA) and math with a cohort of students who were never English learners (non-ELL). We used propensity score matching…

The study addressed the gap in fifth-grade science proficiency between English language learners (ELLs) enrolled in two different science programs in a large school district in the Southeast United States. The Inspire program was implemented in 125 schools, while a combination of Inspire and Promoting Science among English Language Learners…

While multiple valid measures exist for assessing outcomes of environmental education (EE) programs, the field lacks a comprehensive and logistically feasible common instrument that can apply across diverse programs. We describe a participatory effort for identifying and developing crosscutting outcomes for Environmental Education in the…

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…

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…

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 purpose of this quantitative, correlational study was to analyze the extent to which the proportion of IEP students in inclusionary classrooms covaried with turnover intention for K-5 general education teachers in Florida. The researcher employed a quantitative research approach with a correlational research design. The sample was drawn on…

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…

The Learning Team at The Florida Aquarium in Tampa received funding in 2014 to create and conduct a long-term outdoor learning experience for Hillsborough County, Florida, fifth-grade students. The program was designed with four parts to optimize students' experiences in their local watershed, including both classroom and field activities. This…

The purpose of this study was to understand the nature of writing instruction across time and grade bands. We used quantitative and qualitative analyses of teacher interviews and video records of classroom instruction of English language arts writing instruction in 97 fourth- through eighth-grade classrooms in 2010 and 2018. Video records showed a…

Many studies conducted in the last decades report that very few elementary-grades students understand the meaning of = in mathematics, and that upper-elementary students do not understand it any better than the lower-elementary students do. Using data from thousands of Florida elementary students, we show that students in Florida perform ten to…

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…

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…

Educators, researchers, and policy makers concerned about college under-enrollment among underserved groups of students have traditionally focused reform efforts at the high school level. Over the last several decades, however, there has been a growing interest in improving college readiness beginning at the elementary level. Recently, the…
