RESUMO
OBJECTIVE: Providing video recordings of lecture material may enhance student flexibility, but does it alter attendance or influence their grade? This project assessed the extent and purpose of video usage by students and evaluated their impact on course performance within first-year basic science courses in a chiropractic curriculum. METHODS: All first-year students enrolled at a chiropractic college based in the United States were invited to complete a retrospective survey regarding video usage, attendance, and study behaviors for basic science courses they were enrolled during the previous term. Grades were third-party obtained for each consenting student. Statistical analysis included descriptive statistics and independent t tests for each course. Effect size using Cohen's d was calculated for all statistically significant courses (p < .05). RESULTS: Overall, 260 students completed the questionnaire assessing 18 courses in total. The perceived helpfulness of video recordings was associated with heavier usage, primarily to study for exams. Shorter summary videos were preferred by 78% of students over full lecture recordings. Use of videos to replace lectures increased from 21.9% to 53.2% in first through third trimester, respectively. Video use in Neuroanatomy I, Neuroanatomy II, Gross Anatomy II, Organ Histology, and Endocrinology were associated with lower exam scores and overall grades (p < .05), yielding moderate to large effect sizes. CONCLUSION: Videos were used < 1 hour per week, primarily to study for exams. When used as a study tool, video use decreased course performance. Rewatching videos to prepare for exams may be mistaken for mastery of material.
RESUMO
OBJECTIVE: To describe peer-reviewed literature on chiropractic faculty participation in research and identify important barriers and facilitators. METHODS: We conducted a scoping review using comprehensive searches of relevant databases from inception through November 2022. English language publications of any design were included, with search terms consisting of subject headings specific to each database and free text words related to chiropractic, faculty, and research. Primary and secondary reviewer teams performed article screening and data abstraction using Covidence software, with primary reviewers responsible for consensus. Data were entered into evidence tables and analyzed descriptively. RESULTS: A total of 330 articles were screened, with 14 deemed eligible including 8 cross-sectional/correlational studies and 6 narrative reviews/editorials. Article publication dates ranged from 1987 to 2017. No intervention studies were identified. Facilitators of chiropractic faculty research included research assignment as primary role, institutional culture promoting research, and dedicated release time. Barriers included teaching/clinic assignments, lack of incentives and mentorship, and teaching load. Qualitative results identified 5 domains impacting faculty research: demographics/professional roles; personal empowerment; research culture; institutional setting/policies; and research training. CONCLUSION: Our scoping review found a paucity of recently published articles on chiropractic faculty participation in research. Educational institutions building research capacity among chiropractic faculty must establish cultural environments where scholarship is expected, rewarded, and valued. Tangible support, such as research policies, resources, and space, advanced training, funding, and release time, must be available. Faculty are encouraged to build upon key facilitators, evaluate interventions to address barriers to chiropractic faculty research, and publish their results.
