This study evaluated a scholarship support program, "Mathematics as a Common Language in Science," that was funded by the National Science Foundation (NSF). Running from 2015 to 2020, the scholarship support program assisted 31 students to major in chemistry, physics, or mathematics with the intent of supporting these students to enter…

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…

This ex-post facto quantitative study examined how a comprehensive STEM education program impacts high school students' ACT math and science scores as well as their attitudes toward STEM. Using data from one STEM-designated school, the researcher examined ACT math, science, and STEM results for students who took the ACT in the Spring of 2024,…

This dissertation presents an applied research study focused on improving ACT mathematics scores in a rural Mississippi independent school. The study is designed to evaluate the effectiveness of increased mathematics instructional time and curriculum mapping on improving the percentage of students meeting the College Readiness Benchmark scores on…

The goal of the paper is to understand to what degree the student success depends on teaching practices and materials, and to what degree it is due to differences in background, including prior knowledge, skills, preparation, abilities, etc. We analyzed the existing research on outcomes of the SAT and ACT in the United States and the Unified…

American colleges are redesigning the ways in which they offer remedial courses, including mainstreaming students into college-level courses and making greater use of learning-technology to tailor the curriculum to students' specific academic needs. Exploiting a statewide cutoff on a remediation placement exam along with data on student outcomes…

This study explored the mathematics course placement process for incoming students in an all-boys Catholic high school. The sequential nature of mathematics significantly impacts students' opportunity to learn; moreover, the mathematics course taken by a student during ninth grade can have far-reaching effects. Previous studies have found that…

Community colleges began as a way to offer higher education to those that wanted it but could not leave home to further their degree. As they evolved, they began allowing students to be admitted with very little admission requirements. The lack of admission requirements led to students being admitted into community colleges that were not prepared…

Using simulation-based inference (SBI), such as randomization tests, as the primary vehicle for introducing students to the logic and scope of statistical inference has been advocated with the potential of improving student understanding of statistical inference and the statistical investigative process. Moving beyond the individual class…

Algebraic thinking and strategy flexibility are essential to advanced mathematical thinking. Early algebra instruction uses 'missing-operand' problems (e.g., x - 7 = 2) solvable via two typical strategies: (1) direct retrieval of arithmetic facts (e.g., 9 - 7 = 2) and (2) performance of the inverse operation (e.g., 2 + 7 = 9). The current study…

Problem Roulette (PR), an online study service at the University of Michigan, offers points-free formative practice to students preparing for examinations in introductory science, technology, engineering, and mathematics courses. Using four years of PR data involving millions of problem attempts by thousands of students, we quantify the benefits…

The purpose of this quantitative observational study was to identify the differences in high school student test scores on the ACT ELA composite tests and ACT math test for students attending school in union and unified districts in Arizona. Arizona has two options for public high school districts, 9-12 (union) and K-12 (unified). The researcher…

In spring 2015 Mississippi began testing the college readiness of all grade 11 public high school students and found that approximately 18 percent were ready for college math, a percentage that had changed little by 2017/18. This study examined: (1) the sequences of math courses that Mississippi students took in grades 6-11; (2) the math…

Accurate placement into an initial college mathematics course is a key step toward the successful completion of college mathematics and, eventually, a college degree. Conversely, misplacement in mathematics may lead to a reduced likelihood of course completion and degree attainment. This study investigated the ability of two placement models to…

The purpose of this study was to determine if the 1- and 2-term retention rates for students with the same ACT mathematics subsection scores were different between students who took a regular section of Probability and Statistics and students who took a learning support section of the same course. The subjects of this study were 2,714 students…
