The following study shows how reparameterizations and constraints of the general linear model can serve to parse quantitative and qualitative aspects of predictors. We demonstrate three different approaches. The study uses data from the High School Longitudinal Study of 2009 on mathematics course-taking and achievement as an example. Results show…

Introduction: Bullying among adolescents is a global public health issue prevalent in schools, posing significant risks to positive adolescent development. Studies have shown that bullied adolescents tend to engage in more bullying perpetration, but this underlying process of longitudinal correlation has not been fully elucidated. Methods: Based…

The National Council of Teachers of Mathematics (NCTM), along with several other national organizations, released a joint statement indicating how crucial incorporating data analysis into lessons is (NCTM et al., 2024). Mathematics and gardening may seem like incongruent ideas, but mathematics, specifically data analysis, infiltrates activities…

Famous people can positively influence young people by serving as examples of how to be a good person, but very little is known about which famous people youth look up to and why they do so. We coded and analyzed open-response data from 596 adolescents (M[subscript age] = 14.09 years; 58.5% girls, 57.5% White) in the northeastern United States to…

In this article, the authors discuss the Baltimore Secondary Literacy Improvement Community, a teacher fellowship with two goals: (1) to develop pedagogy that supports the reading and writing skills of middle and high school students; and (2) to develop teachers' skills and habits in continuous improvement--behaviors that empower them to drive…

The Cell Phone modeling task centers on a Fermi real-world estimation question. The task and rubric can be used at different grade levels to focus on the modeling process and classroom community. Finding time and space to engage students, especially novice modelers, in mathematical modeling can be a challenge, yet the benefits of modeling are…

This longitudinal study assessed the career aspirations and ultimate careers of 28 academically talented American girls across three time periods: Time 1 (7th/8th grade), Time 2 (11th/12th grade), and Time 3 (current study, 21 years post-Time 1). Two decades after the initial study, these participants are all in their 30s, identify as female, and…

Because studies examining youth drug use often have data with a high proportion of zeros, they often do not meet the assumptions for univariate or linear regression analyses that are typically used. We demonstrate the use of zero-inflated negative binomial regression models to address excessive zeros in drug use frequency on perceptions of…

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…

"Making Room for Change" is an educational book that will be valuable to anyone involved in secondary education. The book will provide clear examples, research, and personal reflections of how building in flexible time can be different from the historic middle and high school scheduling models. Educators of all ages and levels of…

We developed a near-peer mentoring model for high school youth to mentor middle school youth on how to program using MIT App Inventor. The purpose of this study was to investigate: (a) the effectiveness of the near-peer mentoring model for the mentees; and (b) how the mentees' vicarious experience with the near-peer mentors led to changes in their…

The aim of this study is to understand how students' mathematical thinking is activated and nurtured in solving a modeling problem, where the problem situation involves the design of a system. From a STEM integrated perspective, 9th grade students worked on a modeling task aiming to create an identification system based on hand biometrics. The…

Background and Context: Both in- and out-of-school computer science (CS) learning opportunities are expanding, but their influences on CS career interests are unclear. Method: To investigate, we applied multinomial propensity score weighting analysis on a 2021 U.S. nationally representative sample of 4,116 5th-to-12th-grade students. Findings: The…

Although the rate of sexual intercourse among adolescents has increased in Asian countries, including Korea, many sexually active adolescents still do not use contraception. The aim of this study was to identify the risk factors for contraceptive nonuse among adolescents using decision tree analysis of the 2018 Korea Youth Risk Behavior Survey…

Objective: Socially-relevant and controversial topics, such as the climate crisis, are subject to differences in the explanations that scientists and the public find plausible. Scaffolds can help students be evaluative of the validity of explanations based on evidence when addressing such topics and support knowledge gains. Method: This study…
