Objective: To investigate COVID-19's impact on college student health behaviors. Participants: 189 college students. Methods: Participants completed an online survey on behaviors relating to sleep, sedentary activities, and physical activity before and during the COVID-19 pandemic. Comparisons utilized Students' dependent t-test or Wilcoxon…

This study examined opportunities provided for preservice secondary mathematics teachers (PSMTs) to learn reasoning and proof in algebra from the perspective of college instructors. We analyzed interview transcripts of 15 course instructors recruited from three teacher education programs in the United States. We examined the reported opportunities…

Student activities are an important part of the student life experience on college campuses (Barham & Winston, 2006). Student activities professionals are key to helping students become, and stay, engaged during their educational experience (Komives, 2019). While student activities staff provide care and support, the staff themselves are not…

Even though there has been a narrowing of the gender gap in STEM, there is still a pronounced gap in the physical sciences, engineering, and computer science. Females who persist in these fields have a strong STEM identity, including developing specific STEM interests. Females can develop STEM identity through long-term, active involvement in…

In this article, we draw on assemblage theory to investigate how children aged 5 engage with different material surfaces to explore ordinal and relational aspects of number. The children participate in an activity in which they first interact with a strip on the floor, then with a multi-touch iPad application, to work with numbers in expressive…

The purpose of this study was (a) to examine gender and age differences in college students' perceived competence, enjoyment, persistence, and leisure time moderate-to-vigorous physical activity (MVPA), and (b) to utilize a structural equation modeling (SEM) to assess the direct and indirect effects of enjoyment and perceived competence on MVPA…

The development of higher-order thinking skills requires appropriate learning techniques. Project-based learning and integrated learning are learning models that can be used for this purpose. This study aimed to evaluate the contribution of project-based learning and integrated learning to the HOTS development of students in 6 private schools. The…

The various aspects of projectile motion have been analyzed many times in this journal. As a sample, over the years, authors have investigated particular details of the path of a projectile and different situations for launching projectiles. Others have written about a nifty way to determine the maximum height of a projectile, finding the range of…

By organizing an extracurricular seminar, based on the analysis of the intermolecular dispersion action in normal alkanes, a new topological index (named "Intermolecular Interaction Index (IMI)") was proposed to express the intermolecular dispersion force. The IMI has an excellent linear relationship with the boiling point (T[subscript…

One of the greatest challenges in a student's ability to successfully complete reactions in organic chemistry is the ability to differentiate between reactions that have similar structures and proceed through similar reaction mechanisms. Featured in this article is an interleaved reaction review activity called a reaction web. Students are divided…

We present two simple classroom exercises designed to explain challenging concepts in conformation for students beginning organic chemistry. These macroscopic demonstrations serve as analogies to bridge students' understanding of flat two-dimensional drawings to real three-dimensional molecules. In the first demonstration, an apple is drawn from…

Background: Adolescents with intellectual disabilities are insufficiently physically active. Where interventions have been developed and delivered, these have had limited effectiveness, and often lack a theoretical underpinning. Aim: Through application of the COM-B model, our aim is to explore the factors influencing adolescent physical activity…

Four volunteer participants who used the services of the Office of Accessibility Services (OAS) on our campus attended three sessions where they were interviewed about inclusivity and (a) taught an art technique; (b) taught to do the technique with a partner; and (c) used the technique with a guest whom they identified as having impacted their…

This simulation provides public administration, public policy, and management students and practitioners with an immersive disaster scenario. The table-top exercise provides an example of how municipal leaders can prepare for disaster scenarios and the importance of embedding social equity into disaster response. Additionally, it provides an…

Purpose: To explore undergraduate students' experiences leading and facilitating an out-of-school-time (OST) physical activity program for middle school girls. Method: Five female undergraduate students (N = 4 Black or African American) participated in semistructured individual interviews and submitted weekly reflections during their time leading…
