Study buddy learning is associated with academic success in undergraduate science courses

This study reports on the outcomes of a formal peer-learning program for undergraduate science students. We implemented a cohort-based study buddy program in which high-scoring students (mentors) and lower-scoring peers (proteges) were invited to form study groups based on their first assessment scores in a given course. We then compared the performance of participants versus non-participants on subsequent assessments, while examining separately the effects for mentors and proteges. Results showed similar participation benefits for students in both mentor and protege roles. These findings emphasize the value of reducing barriers to collaborative learning in higher education and highlight the study buddy program as a cost-effective and scalable approach to enhance students educational experiences.

On the reliability of wearable technology: A tutorial on measuring heart rate and heart rate variability in the wild

Wearable sensors are quickly making their way into psychophysiological research, as they allow collecting longitudinal and ecologically valid data. The present tutorial considers fidelity of physiological measurement with wearable sensors, focusing on reliability. We elaborate why ensuring reliability for wearables is important and offer statistical tools for assessing wearable reliability for between participants and within-participant designs. The framework offered here is illustrated using several brands of commercially available heart rate sensors. Our hope is that by systematically quantifying measurement reliability, researchers will be able to make informed choices about specific wearable devices and measurement procedures that meet their research goals.
