This article reports on an evaluation the effectiveness of e-mailed grade "nudges" on students' performance and engagement in an introductory statistics course for undergraduate health science students. In 2020-2021, 358 students were randomized to an e-mail (n = 178) or no e-mail (n = 180) group. The intervention e-mail contained…

Self-efficacy is associated with a range of educational outcomes, including science and math degree attainment. Project-based statistics courses have the potential to increase students' math self-efficacy because projects may represent a mastery experience, but students enter courses with preexisting math self-efficacy. This study explored…

The maintenance and escalation of intergroup conflicts have been explained by negative emotions and attitudes toward outgroup members. Considering that creative cognition entails the ability to generate diverse and new ideas, we sought to investigate whether creativity may contribute to overcoming negative emotions and attitudes associated with…

This three-manuscript dissertation attempts to answer the question: "How does students' English language proficiency (ELP) inform the availability, structure, and use of English language accommodations and intervention to support the academic achievement of English learner (EL) students?" The question is addressed using three independent…

Background: This study assesses the long-term effectiveness of a lifestyle intervention on cigarette, passive, and hookah smoking in adolescent boys and girls. Methods: One thousand one hundred and fifty-nine adolescent participants of Tehran Lipid and Glucose Study (TLGS) (2001-2004) were followed for 12 years. Participants in the intervention…

The gold-standard for evaluating the effect of an educational intervention on student outcomes is running a randomized controlled trial (RCT). However, RCTs may often be small due to logistical considerations, and resulting treatment effect estimates may lack precision. Recent methods improve experimental precision by incorporating information…

Objective: This study explored predictors of food allergy management in college students, including participants' reported allergy severity, history of allergic reactions, and allergy knowledge. Further, we compared allergy knowledge in participants with food allergy to a matched sample of college students without food allergy. Method:…

Adolescents with attention-deficit/hyperactivity disorder (ADHD) are at heightened risk of experiencing academic difficulties due to organizational deficits. Impairment can be exacerbated through poor sleep hygiene and excessive daytime sleepiness, prevalent sleep challenges for adolescents with ADHD. Given established relationships among sleep,…

Cognitive, numeracy, and motivational factors have been implicated in math achievement. However, few studies have investigated these factors simultaneously and in middle childhood, limiting our understanding of the relative contributions of these factors during an important developmental period. The current study investigated how one numeracy,…

Background/Context: Chronic absenteeism is a serious problem that has been linked to lower academic achievement, diminished socioemotional skills, and an increased likelihood of high school dropout (Allensworth et al., 2021; Gottfried, 2014). As a result, many schools have begun to embrace early warning systems (EWS) as a tool to identify and flag…

Background: Developmental language disorder (DLD) has clear functional ramifications in the areas of social competency, emotion recognition, emotional well-being and literacy skill, which have been found to persist from childhood to adolescence. These domains are important factors during the transition from primary to secondary school in typical…

Small private online courses (SPOCs) have influenced teaching and learning in China's higher education. Learning management systems (LMSs) are important components in SPOCs. They can collect various data related to student behavior and support pedagogical interventions. This research used feature engineering and nearest neighbor smoothing models…

Motivation and self-concept count among the educationally most relevant factors and the evaluation of many educational interventions requires their valid measurement. The present study examined the psychometric properties of a shortened version of the Students' Approaches to Learning questionnaire measuring 10 distinct motivational and…

We propose that machine-learned computational models (MLCMs), in which the model parameters and perhaps even structure are learned from data, can complement extant approaches to the study of text and discourse. Such models are particularly useful when theoretical understanding is insufficient, when the data are rife with nonlinearities and…

Purpose: Morphological awareness (MA), the ability to reflect on and manipulate the smallest language units within a word, has been identified as an essential metalinguistic awareness to predict literacy development. In this study, we examine whether an online gamified English MA programme is more effective than physical face-to-face instruction…
