Delay discounting tasks measure the relation between reinforcer delay and efficacy. The present study established the association between delay discounting and classroom behavior and introduced a brief measure quantifying sensitivity to reward delays for school-aged children. Study 1 reanalyzed data collected by Reed and Martens (J Appl Behav Anal…

Contextual interference is an established phenomenon in learning research; random practice schedules are associated with poorer performance, but superior learning, compared with blocked practice schedules. We present a secondary analysis of N = 84 healthy young adults, replicating the contextual interference effect in a time estimation task. We…

The choice of cortisol sampling times in early childhood studies varies widely. Given that recommendations on sampling protocols are largely based on adults, the present study aimed to broaden current knowledge by examining how reliably cortisol measures obtained at different daytimes would reveal between-individual differences in toddlers'…

This was a causal comparative study examining and comparing student class schedules and credit load to academic success by grade point average earned at a Tennessee community college. The results of this causal comparative study utilizing a mixed methods data collection revealed significant differences in credit load, grade point average (GPA) and…

The longstanding call to prioritize science education has gained momentum, particularly with the noticeable changes aligned with reform-era practices. This quantitative study explored the relationship between policy, time allocation, and teacher practices in elementary science education, guided by constructive learning theory as the theoretical…

This dissertation examines the effects of neighborhood characteristics on Detroit Public School Community District students' attendance rates for the 2018-19 school year. First, I analyze the effects of daylight savings time, relative to school start time, on absences for elementary and middle school students. By observing the natural change in…

Purpose: The purpose of this study is to use the optimization modeling method to explore whether there is an ideal arrangement of course enrollments that can yield optimal parking demand and supply on college campuses. Design/methodology/approach: Using the University of Louisville as a case study, this study deploys a three-step analytical…

This study focuses on the analysis of certain performance predictors for calculus I. We collected data from 717 students from 2013 through 2018 at a southeastern university in the United States to explore any correlation between course times (particularly very early versus the rest) and student performance in this specific course, along with a…

This research study was designed to investigate music teachers' perceptions of job satisfaction, professional development, and administrative support and to explore possible existing relationships between music teacher job satisfaction and number of hours of music related professional development while exploring possible relationships between…

The benefits of afterschool activity participation for youth development are well-documented. An interesting question dominating this field is whether there is a threshold at which point participating in too many activities (breadth) and spending too much time in those activities (intensity) is negatively associated with desirable outcomes. Using…

School shootings have been a constant looming threat for students across the US, with the number of shootings on campuses dramatically increasing in recent years. In response, schools have instituted preparedness and response measures, including school-shooter drills. This essay examines the relationship between active-shooter drills and two…

The purpose of this study was to explore the psychometric properties of the Portuguese version of the Child Routines Questionnaire: Preschool (CRQ:P), a parent-report measure developed to assess daily routines specific to preschool-age children. Participants included 208 parents of preschool children (M[subscript age] = 3.97 years old; SD = 0.95;…

Sleep right after studying new material is more conducive to memory than a period of wakefulness. Another way to counteract forgetting is to practice retrieval: taking a test strengthens memory more effectively than restudying the material. The current work aims at investigating the interaction between sleep and testing by asking if testing adds…

This study investigated English first language (L1) speakers' motivation for learning Chinese as a second language (L2) in Australia and the links of underlying motivational components to learner sociobiographical (e.g. gender and reasons for learning) and language learning variables (i.e. experience abroad, hours of self-study, and speaking with…
