Because of the need to provide fine-grained longitudinal diagnostic feedback, longitudinal cognitive diagnosis is an emerging approach that integrates cross-sectional cognitive diagnosis models (CDM) with longitudinal data analysis techniques. By adopting the generalized longitudinal higher-order log-linear CDM, this study attempted to track the…

This dissertation includes three individual articles that explore the relationship between witnessing bullying and defending behavior among students who are bystanders of bullying. Chapter One provides the rationale and purpose of this dissertation and an overview of the three articles that comprise it. Chapter Two employed a cross-sectional…

Objective: Extreme sport participation and injury rates have increased in recent decades. This study aimed to investigate sub-dimensions of impulsivity and sensation seeking that contribute to participation and injury risk in extreme sports. Participants: Data included cross-sectional survey responses from 7,109 college students (Mage=19.68, SD =…

Current theoretical and operational definitions of underachievement require that students show sustained suppressed academic achievement. Yet, early detection may allow for effective intervention before underachievement becomes a chronic issue. While existing identification procedures were not designed to detect underachievement before low…

As stress in students has increased in the last years, factors predicting stress need to be investigated. The aim of the present study was to replicate previous findings using the demand-control model and to examine the role of emotional distress in a transactional model (inspired by Lazarus' transactional stress model). "Stress, mental…

The resegregation (i.e., overrepresentation) of Black and Latinx students in special education is a longstanding concern of scholars, researchers, and policy makers in the United States. Therefore, we conducted a critical investigation to better understand the causes of resegregation, student experiences in special education, and anti-racist…

Background: Relational victimization (RV) is a significant threat to adolescent mental health and social adaptation in China. However, its developmental characteristics during the school transition period are poorly understood. Finkelhor's developmental victimology framework provides a comprehensive lens to explore factors influencing RV's…

This special issue consists of 20 articles that focus on issues related to Eisenberg and colleagues' (Eisenberg, Cumberland, & Spinrad, 1998; Eisenberg, Spinrad, & Cumberland, 1998) model of emotion socialization processes and its relevance for understanding a range of aspects of children's socioemotional functioning. The various papers…

This qualitative, non-experimental meta-synthesis explored the antecedents, consequences, and interventions of both active and passive procrastination among university students. Based on the academic procrastination paradigm proposed by Schraw, Wadkins, and Olafson in 2007, the study synthesized and interpreted the findings of twelve purposefully…

This study addresses teachers' activity when working with digital technologies (DT) in their classrooms. We build upon a model that considers teaching as managing "open dynamic situations." Within the model, teachers' activity is viewed as diagnosing students' mathematical activity, managing uncertainties due to the characteristics of…

COVID-19 disrupted schools across the country. Students and teachers were asked to work together virtually. During this virtual experience the students at Frederick County Middle School struggled to complete learning activities independently. An improvement science approach was used to investigate this problem. Through the improvement science…

Evidence-based early interventions for autism spectrum disorder (ASD) have been shown to improve child outcomes and quality of life (Lord et al., 2018; Reichow et al., 2018; Smith & Iadarola, 2015). However, response to intervention is variable across both children and implementation contexts. Understanding factors that influence this…

Mindset interventions, which shift students' beliefs about classroom experiences, have shown promise for promoting diversity in science, technology, engineering, and mathematics (STEM). Psychologists have emphasized the importance of customizing these interventions to specific courses, but there is not yet a protocol for doing so. We developed a…

Despite the many social and political advances lesbian, gay, bisexual, transgender, and queer (LGBTQ) individuals have achieved, youth within these populations continue to be at elevated risk for suicide. Because adolescents spend most of their day in academic settings, school district staff have ample opportunity to identify and assess suicide…

Metamotivational knowledge is a burgeoning area of study. It refers to people's knowledge about motivation, and it has been shown to contribute to motivation and behavioral outcomes. The current study bridges metamotivational knowledge with self-determination theory (SDT), one of the most prominent theories of academic motivation. SDT proposes…
