What is Better? Asynchronous vs. Synchronous Supplemental Resources in Pharmacy Education: Peer-Teaching Perspectives 

By: Collin Blackwell, PharmD Candidate 2025 and Renee’ Acosta, RPH, MS

Every pharmacy educator has encountered the question, “Do you have any extra study materials for us?” Students are encouraged to seek additional resources, but identifying effective supplemental materials is challenging. One way pharmacy schools address this concern is by hiring upper-level students who provide peer-teaching for students.1 The concept of peer-teaching focuses on acquiring knowledge or skills from other students with similar experience or academic levels.1 Peer-teaching is concentrated on sharing academic knowledge, while peer-mentoring offers broader guidance, including academic strategies, career advice, and personal development. Research highlights the positive impact of peer-teaching, with students frequently noting enhancements in their perceived and actual performance.1-3 Peer-teaching also supports students experiencing academic difficulties or undergoing remediation.4-5 Students in these peer-teaching roles contribute positively to learning through various methods, including supplemental instruction presentations, exam reviews, providing practice questions, and tutoring.1-5 Determining the most beneficial peer-teaching supplemental resources needs further exploration.

What I Did? 

For three years, I served as a peer-teaching assistant for a first-year Medicinal Chemistry course. In the Fall of 2022, I employed both synchronous (involving real-time interaction between myself and students) and asynchronous (not requiring real-time interaction) supplemental education modalities. Synchronous resources included special lecture lessons on beta-lactam mechanisms and drug metabolism pathways, tutoring, office hours (designated weekly time to meet with students), and exam review sessions. Asynchronous resources included practice questions, study guides, and video recordings. Although not mandatory, students were encouraged to engage with these resources if seeking more help. At the end of the course, 94 students completed a survey assessing the usefulness of the supplemental materials. 

What I Found?

Students generally found the supplemental resources extremely helpful for exam preparation and preferred asynchronous resources (study guides, practice questions, and video recordings) over synchronous resources (exam reviews, special lecture sessions, office hours, and tutoring appointments). Figure 1 highlights the supplemental modalities used by first-year students in 2022, and Figure 2 illustrates the top three supplemental resource modalities students found most helpful. Table 1 shows how students rated the helpfulness of each resource on a five-point Likert scale and could indicate if a resource was not used. Many students reported that exam reviews, practice questions, and study guides were the most helpful for exam preparation. Although video recordings were used and well received, they were less popular. Additionally, many did not take advantage of tutoring, office hours, or special lectures. These results suggest that students prefer and engage more positively with asynchronous resources. Notably, exam review sessions were the most utilized resource and ranked highest among students’ top three supplemental modalities despite being a synchronous format. One possible explanation is that students considered exam reviews to be high-yield content that supported their exam preparation.

Call to Action

This analysis does not definitively identify the most helpful resource; however, it does highlight the value of asynchronous supplemental materials as accessible learning tools, and that exam reviews are a beneficial synchronous option. While these results are only from a single course of first-year pharmacy students, future research can investigate if similar trends emerge across different pharmacy school courses and years of the professional curriculum

What supplemental education materials have student pharmacists found beneficial at your institution?
