Here, we assess whether quantity representations are influenced by the perceptual biases hypothesized to manifest in depressive individuals. In contrast to this clinical model, several prominent models of numerical cognition assume that quantity representations are abstract, and therefore are independent of the items that are being quantified. If…

A longstanding critique of homeschooling is that it isolates children from mainstream society, depriving them of social experiences needed to thrive as adults. Although a small number of empirical studies challenge this criticism, this research tends to be derived from self-reports of homeschooling parents about their children. In this study,…

The purpose of this study was to examine the relationships among homework time, homework frequency, and learning achievements of Taiwanese students. Applying a 2-level hierarchical linear modeling on the TIMSS 2007 and 2011 data, our findings were as follows: (1) Within the context of TIMSS 2007 and 2011 students, the frequency of mathematics…

This study adopted a meta-analysis to explore the effectiveness of unplugged activities (UA) and programming exercises (PE) teaching approaches on computational thinking (CT) education. Through a two-stage literature collection and selection process, 29 articles were included in the meta-analysis, 31 independent effect sizes (16 of UA and 15 of…

Research has shown that students differ in their abilities to evaluate the credibility of online texts, and, in general, many perform poorly on online evaluation tasks. This study extended current knowledge by examining students' abilities to justify the credibility of online texts from different perspectives, thus providing a more nuanced…

Whereas accuracy is used as an indicator of cognitive flexibility in preschool-age children, reaction time (RT), or a combination of accuracy and RT, provide better indices of performance as children transition to school. Theoretical models and cross-sectional studies suggest that a speed-accuracy tradeoff may be operating across this transition,…

The Postsecondary Data Partnership (PDP) is a service of the National Student Clearinghouse established in 2017 to empower institutions with more comprehensive data, easier analysis, centralized reporting functions, and interactive visualizations. Since its inception, over 500 colleges and universities have participated in the PDP. The 2022 PDP…

Policymakers have renewed calls for expanding instructional time in the wake of the COVID-19 pandemic. We establish a set of empirical facts about time in school, synthesize the literature on the causal effects of instructional time, and conduct a case study of time use in an urban district. On average, instructional time in U.S. public schools is…

Early college high school (ECHS) and dual enrollment programs offer opportunities for students to work toward their 2-year degree while still in high school. The problem for this study was that the ECHS and dual enrollment programs had not been compared to see if they facilitated 2-year college degree completion compared to one another and to a…

The purpose of this quantitative study was to examine the impact of blended professional development on teacher efficacy. The variables hours of blended learning, subjects taught, and years of experience were investigated. Additionally, teacher efficacy was analyzed across domains of student engagement, instructional practices, and classroom…

This qualitative phenomenological study explores teachers' beliefs regarding students' physical activity and the effects on academic performance in a low-socioeconomic school district in a Midwestern state. This study investigates the importance of physical activity through Albert Bandura's Social Cognitive Theory of Self-Efficacy and John Dewey's…

The purpose of this qualitative descriptive case study was to examine teachers' perceptions on how their engagement and satisfaction in professional development opportunities influence their efficacy in applying the skills learned. Three research questions guided the study: How do teachers describe their efficacy in applying skills learned from…

It is not uncommon for teachers to feel neglected when leaving a traditional one-and-done professional development workshop. Too often teachers are left to fend for themselves as they begin to implement new strategies into their teaching. Teachers need and deserve continued support as they attempt to carry out the lessons learned in these…

The purpose of this quantitative research study is to determine through the foundational lens of the temporal motivational theory, if active procrastinators outnumber passive procrastinators, and outperform them on an online mathematics final exam. Conducted at an associate's degree granting institution in the southeastern region of the United…

The present grant funded study by the Office of Research and Sponsored Projects investigated the effects of a chronological multicultural mathematics (CMM) framework on math identity and math achievement of student participants enrolled in two virtual post-secondary developmental math courses (N = 9). The students were selected due to an inability…
