U.S. Department of Education research indicates that early warning indicator systems are being used in at least half of high schools in the United States. Previous findings from an efficacy study of one early warning indicator and response system, the Early Warning Indicator (EWI) team model, indicated that ninth grade students in schools using…

Background: Mental disorders most likely manifest during adolescence, providing opportunities for schools and professionals to implement standardized mental health literacy (MHL) interventions to support improvement of mental health outcomes. Purpose: This study aimed to evaluate the impact of an MHL intervention (the Guide) on knowledge, stigma,…

The purpose of this program evaluation was to evaluate the impact of CORE District's Breakthrough Success Community (BTSC) Program at an urban Title I high school located in Southern California. BTSC aims to improve the ninth-grade experience through a focus on five key change drivers and the implementation of improvement science. Through teacher…

This dissertation examines how implementing READ 180 for 9th grade students affects their Lexile level and reading ability. The research focuses on two questions: what changes were noticed in the students' Lexile levels? and what program recommendations can be made moving forward? The methodology used was PDSA and improvement science. The study…

A history of trauma can have a significant negative impact on the functioning of a student in the school environment. Check & Connect, a school engagement and dropout intervention program, has been found to have positive effects on student school engagement and decrease the likelihood of dropping out of school. However, a review of the Check…

Targeted sexual health education to redress these disparities requires creative and inclusive approaches that consider personal and community challenges and strengths. This study piloted a novel intervention: SExT: Sex Education by Theatre, a theatre-based,…

This study examined the effects of Reading Intervention for Adolescents (RIA) and a mentoring intervention (MI) implemented for 1 year with ninth-grade English learners (ELs) with reading difficulties. Eligible students enrolled at three urban high schools were randomly assigned to the RIA (n = 142), MI (n = 163), RIA and MI (n = 164), or…

A Southeastern school district created freshman academies to assist freshman students with strategies and support they need to combat ninth-grade failure successfully, but little change was observed. The purpose of the study was to explore teachers' perceptions of the freshman academy's transition program structure, benefits, challenges, and…

This study examined "backward transfer," which we define as how students' ways of reasoning about previously encountered concepts are modified when learning about new concepts. We examined the backward transfer produced when students learned about quadratic functions. We were specifically interested in how backward transfer may vary for…

This study was a quasi-experimental design (QED) that examined the impact of Intervene K-12 tutoring on mathematics achievement for Grade 9 ELL students identified by HPS as having experienced considerable learning disruptions as a result of the COVID-19 pandemic and having recently arrived in the United States. Achievement gains for treatment…

Relevance interventions have shown a great potential to foster motivation and achievement (Lazowski & Hulleman, 2016). Yet, further research is warranted to test how such interventions can be successfully implemented in practice. We conducted a cluster-randomized trial in ninth-grade math classrooms to test the effectiveness of a relevance…

Background: Youth with ADHD are at risk of academic impairments, dropping out of high school, and dysfunction in young adulthood. Interventions delivered early in high school could prevent these harmful outcomes, yet few high school students with ADHD receive treatment due to limited access to intervention providers. This study will test a…

Check-In/Check-Out-High School is a version of CICO, an established Tier 2 intervention designed to improve student academic and social behavior, adapted to increase effectiveness and…

Dysfunctional movement, a suggested contributing factor for musculoskeletal pain and injury, appears to increase as adolescents experience puberty. This study investigated dysfunctional movement among a group of ninth-grade physical education students to determine if a standardized functional movement warm-up (FMWU) would improve movement quality…

The effect of the "Adapted-Coping with Stress" (A-CWS) intervention on social support coping was examined, using a randomized controlled trial design. The participants were 410 ninth-grade students (ages 14 to 16 years and mostly African American) living in low-resourced neighborhoods. Participants were randomly assigned 1:1 to either…
