This study draws on complete friendship network data on two first-year biological sciences cohorts at a selective university in the United States to investigate how and to what extent allocating students to curricular groups and grading their performance in class shape (1) processes of friend selection at the dyadic level and (2) friendship…

Remembering information about others is important but challenging in various social contexts. For instance, in long-term collaborative educational settings, students often need to choose peers for academic support. In different contexts, the selection process can depend on group awareness, i.e., the state of being informed about relevant social or…

The purpose of this research was to investigate the needs of parents and guardians who enroll their children in Out of School Time (OST) Programs in Philadelphia. It provides further guidance toward formalizing how OST programs recruit students and their families, and assessing parental engagement activities from a consumer's perspective. Applying…

We introduce and evaluate three tests for publication selection bias based on excess statistical significance (ESS). The proposed tests incorporate heterogeneity explicitly in the formulas for expected and ESS. We calculate the expected proportion of statistically significant findings in the absence of selective reporting or publication bias based…

Contribution: Instructors are leveraging open-source software (OSS) as a way to experience authentic examples of software problems with their students. Recommender engines might assist students in selecting the right project based on metrics mined from project repositories (e.g., GitHub). This vision is realized through GitMate, a GitHub-based…

In recent years, the discipline of statistics has begun reckoning with its difficult history. Institutions are reconsidering names that have honored key historical figures in statistics who have deep ties to eugenics movements and racial and class prejudice. These names, however, continue to appear in our classrooms, where we teach the methods…

Information can be conveyed via multiple channels such as verbal and gestural (visual) channels during communication. Sometimes the information from different channels does not match (e.g., saying right while pointing to the left). How do addressees choose which information to act upon in such cases? In two experiments, we investigated this issue…

The basis for mastering neurophysiology is understanding ion movement across cell membranes. The Electrochemical Gradients Assessment Device (EGAD) is a 17-item test assessing students' understanding of fundamental concepts of neurophysiology, e.g., electrochemical gradients and resistance, synaptic transmission, and stimulus strength. We…

Against intuition, a set of "desirable difficulties" has been touted as a way in which to improve learning and lengthen retention. This includes, for instance, varying the conditions of learning to allow for more active, effortful, or challenging, contexts. In the current paper, we introduce data that show that, on the contrary, learning…

Choosing a course of study is one of the most consequential decisions a university student will make. While there is considerable literature investigating how personality influences students' choice of discipline, there is currently no evidence about how students cluster in disciplines relative to their civic-mindedness. This is an important gap…

Amid concerns about creating internationally recognized world-class universities in China, this study aims to explore the factors that influence the selection of two prestigious universities in China, namely Tsinghua and Beida, by high school students. In light of concerns surrounding the establishment of globally renowned universities in China,…

Pregnancy is a frequently applied exclusion criteria for many forms of research. Common justifications for this exclusion include the potential for teratogenicity, as well as the potential for physiologic changes in pregnancy to impact the research itself. The systematic exclusion of pregnant persons from clinical studies has created a significant…

This study examined differences in bilateral skill proficiency and frequency of use between selected and nonselected under-17 male intercounty academy Gaelic footballers. Participants (N = 82, mean age = 15.54 years, SD = 0.27) were retrospectively grouped as selected (n = 19) and nonselected (n = 63) for the final squad. A discrete skills test…

Creative idea selection--the selection of the most creative idea(s) from available ideas--is an important yet understudied topic. Creative idea selection can be performed by the idea generator (i.e., "intrapersonal" selection) or by another person (i.e., "interpersonal" selection). In the current research, we examined whether…

In the realm of literacy education, curriculum is driven by politics, finances, standardization, and accountability. How specified curricular materials make their way into the classroom often baffles educators. The one thing they know is it is "isn't the one we voted for." This study includes a review of literature on how curricula were…
