Georgia adopted science standards encouraging teachers to use inquiry-based instruction in science instruction in 2016 to improve science exam scores. The problem was a lack of improvement in science exam scores in middle school and high school students in a small rural school district in South Georgia since inquiry-based standards have been put…

We examined relationships between measures of adaptive behavior, cognitive ability, and autism symptom severity in 1458 preschool-aged children with autism from the Study to Explore Early Development. While publications commonly describe autistic children as "low-" or "high-functioning" based on cognitive ability, relying…

For years Georgia's HOPE Scholarship program provided full tuition scholarships to high-achieving students. State budgetary shortfalls reduced its generosity in 2011. Under the new rules, only students meeting more rigorous merit-based criteria would retain the original scholarship covering full tuition, now called the Zell Miller Scholarship,…

English language (EL) students' English language proficiency (ELP) scores directly impact a school district's College and Career Ready Performance Index (CCRPI) score, measuring whether Georgia meets accountability requirements. English language proficiency for English language learners (ELLs) is measured by the ACCESS for ELLs assessment. The…

We use administrative panel data from seven states covering nearly 3 million students to document and explore variation in "academic mobility," a term we use to describe the extent to which students' ranks in the distribution of academic performance change during their public schooling careers. On average, we show that student ranks are…

This quantitative study used archived student records to determine which high school and postsecondary factors are the most significant predictors of college retention among 2,175 students enrolled at the University of West Georgia in Fall 2018. A two-tailed t-test was conducted for research questions one and two to analyze the high school GPAs…

The current study was a retrospective mixed-methods quasi-experimental design (QED) study to determine the effects of Progress Learning on Grades 6-8 mathematics and ELA achievement by comparison growth on the Georgia Milestones Mathematics and ELA assessments of students who received Progress Learning services, in relation to students that did…

This research investigates whether teachers' unions influence student academic achievement in Southern states that prohibit collective bargaining. Our data are from the School and Staffing Survey and the Stanford Education Data Archive. We measure the strength of teachers' unions by union membership rate and meet-and-confer status of a district…

When school personnel and parents complete school climate surveys, results can inform team action planning to improve perceptions of school climate. Further, school climate data can assist in considering questions related to equity, disproportionality, and cultural responsiveness and appropriateness. The freely-available School Climate Survey…

Diesel emissions from school buses expose children to high levels of air pollution; retrofitting bus engines can substantially reduce this exposure. Using variation from 2,656 retrofits across Georgia, we estimate effects of emissions reductions on district-level health and academic achievement. We demonstrate positive effects on respiratory…

Cooperative learning is a proven teaching strategy that teachers have been using for over 40 years. Teachers often group students heterogeneously so that students who are lower achieving are learning with and from higher achieving students. The purpose of this study was to test homogeneous and heterogeneous grouping while using cooperative…

The unprecedented growth of Spanish-English dual language learners (DLLs) in new destination states (e.g., Georgia, Indiana, South Carolina, Tennessee) calls for better understanding of the relation between their bilingual vocabulary skills and English reading achievement. The current study focused on school-age Spanish-English DLLs (N = 60) in…

The purpose of this study was to determine to what degree significant academic gains occurred in English/language arts and mathematics achievement for students who attended the after-school program compared to the students who did not participate in the after-school program. This study was significant in that it examined the impact of structured…

This quantitative correlational non-experimental study examined the predictable relationship between the ACCESS for English Language Learners scale score and the Georgia Milestones English Language Arts (GMAS-ELA) standardized assessment for reclassified fifth-grade English language learners during the 2018-2019 school year. The problem addressed…

Using administrative data from Georgia, we provide the first study of the full set of college entrance exam-taking strategies, including who takes the ACT and the SAT (or both), when they take the exams, and how many times they take each exam. We have several main findings. First, one-third of exam takers take both the ACT and SAT. Second, we see…
