The purpose of this quantitative, quasi-experimental, nonequivalent comparison-group design was to determine if "How to Learn Math: For Students" (Boaler, 2018) had a statistically significant influence on ninth-grade and tenth-grade students' mathematical achievement and the achievement gap across socioeconomic status. Participants…

Guided by the life course perspective, this study investigated the developmental antecedents of contact, closeness/warmth, and negativity in young adults' relationships with their parents. Taking the developmental systems approach, we considered interindividual differences in not only initial levels of parenting quality in early adolescence (Grade…

The purpose of the present study was to determine the role of emotion regulation in the pathway to problematic alcohol use among adolescents with attention-deficit/hyperactivity disorder (ADHD), specifically investigating the total effect of emotion regulation on problematic alcohol use and the indirect effect of emotion regulation through social…

The COVID-19 virus brought on a public health emergency that massively disrupted school systems and learning nationwide. During the 2020-2021 school year, many local education agencies (LEAs) in Pennsylvania and other states adopted remote learning to help slow the virus's spread.

This study examines developmental change across adolescence in the similarity of friends versus nonfriends. This differential in similarity is a key aspect of the organization of the peer context of development: The stronger the correlation between friends for an attribute, the more the attribute delineates clustering and divisions of friendships.…

This study describes the process of defining a hypothetical learning progression (LP) for astronomy around the big idea of "Solar System formation." At the most sophisticated level, students can explain how the formation process led to the current Solar System by considering how the planets formed from the collapse of a rotating cloud of…

"Career Academies" is a dropout prevention strategy for youth considered most at risk of dropping out of high school.

Since implementing No Child Left Behind, schools have improved student achievement while also preparing students for the 21st century. Schools continue to strive for 100% proficiency in all subgroups by 2014, but achievement gap exists for students with disabilities. This study used a causal comparative research design to test the concept of…

Although the number of women majoring in engineering and engineering technology has increased in the last few decades, percentages lag behind those in other STEM disciplines. Young women often have misperceptions about the nature of engineering, and that leads to lack of interest. Engineering is often seen as men's work. They do not understand how…

"Exito" means "success" in Spanish, so it is a fitting name for a dropout prevention program. Set in a large neighborhood high school in a low-income, largely Latino section of Philadelphia, Exito supports ninth- and tenth-grade students who are at risk of dropping out of school by providing them with afterschool programming…

Recent research has suggested that differences between intelligent tutor lessons predict a large amount of the variance in the prevalence of gaming the system. Within this paper, we investigate whether such differences also predict how much students choose to go off-task, and if so, which differences predict how much off-task behavior will occur.…

Schools have gone through educational reforms having various focuses on curriculum changes, consolidation, open classrooms, mastery learning, decentralization, shared decisionmaking, legislative mandates and controls, high expectations, integrated thematic instruction, professional development, technology integration, and standards with…
