The COVID-19 pandemic and the resulting changes in schooling have been particularly difficult for students learning the English language. Recent research indicates that nearly 40 percent of English learners (ELs) nationwide were not receiving the services and support they needed to successfully engage with academic content during distance learning…

The successes of corequisite remediation courses and supplemental instruction over traditional remediation courses such as the modular Math Essentials have been widely and recently documented (Logue, Watanabe-Rose, & Douglas, 2016). Corequisite reform is an important strategy to improve student completion of higher education goals. A robust…

This study, conducted at California State University (CSU) in Southern California, focused on student engagement factors and academic performance of supplemental instruction (SI) students concurrently enrolled in a gateway mathematics course. The purpose of this quantitative correlational survey study was to investigate engagement factors employed…

Learning Support Services at the University of California, Santa Cruz is intended to aid students--particularly those who are at highest risk of academic failure--to master the required material and succeed in their courses. It includes two primary components: modified supplemental instruction (MSI) and tutoring. This study uses data from…

Supplemental Instruction (SI) is a well-recognized model of academic assistance with a history of empirical evidence demonstrating increases in student grades and decreases in failure rates across many higher education institutions. However, as college students become more accustomed to learning in online venues, what is not known is whether an SI…

Policymakers face dilemmas when choosing a policy, program, or practice to implement. Researchers in education, public health, and other fields have proposed a sequential approach to identifying interventions worthy of broader adoption, involving pilot, efficacy, effectiveness, and scale-up studies. In this paper, we examine a scale-up of an early…

This study evaluated the efficacy of the Word Learning Strategies (WLS) supplementary program to improve elementary students' vocabulary skills and reading comprehension. The study used a multi-site cluster randomized, experimental design, which randomly assigned 92 4th grade classrooms (n=2558 students) from two cohorts to a treatment or control…

Executive Order (EO) 1110, a major policy adopted by the California State University System (CSU) Chancellor's Office in August 2017, requires CSU campuses to eliminate non-credit-bearing developmental courses in written communication and math/quantitative reasoning, and change how students are placed into entry-level courses in these areas. The…

The purpose of this study was to evaluate the effectiveness of supplemental instruction (SI) as a high-impact intervention for Organic Chemistry at a newly designated Hispanic Serving Institute. Results indicated a significant correlation between SI and academic outcomes, measured by the American Chemical Society (ACS) standardized assessment.…

A convergent mixed methods research design addressed the extent of benefit obtained from reading culturally inclusive prompts (i.e., four brief essays written by Latino authors) to improve essay writing in a developmental (pre-collegiate) English course. Participants were 45 Latino students who provided quantitative data. Chi square analysis…

Creating a collaborative environment across student services and instruction is often more challenging than it may first seem. Although effective collaboration is context specific, keeping student learning at the center of the work is a powerful element in successful collaborations. Grossmont College's first year experience program has attempted…

This doctoral project is a pilot study to assess the effectiveness of a church discipleship co-op designed to convey a biblical worldview to middle and high school students enrolled in charter homeschooling in Southern California. Research by the Nehemiah Institute indicated that 90% of Christian families in the United States send their children…

Fifty-two low performing schools were randomly assigned to receive Spatial-Temporal (ST) Math, a supplemental mathematics software and instructional program, in second/third or fourth/fifth grades or to a business-as-usual control. Analyses reveal a negligible effect of ST Math on mathematics scores, which did not differ significantly across…

This study evaluated variables associated with academic preparation and student demographics as predictors of academic achievement through participation in supplemental instruction (SI) programs for community college students in Science, Technology, Engineering, and Math (STEM) fields. The findings suggest a differential impact of SI outcome for…

In 2013, with a 30% state budget cut after the Great Recession, many of the 450,000 California State University (CSU) students across the 23-campus system were unable to enroll in courses they needed to move closer to graduation; there was a lack of available course sections. In addition to a reduced number of seats available for students, 30% to…
