Medical Students Boost Physiology Scores Through Project-Based Learning
The study evaluated whether early research exposure combined with hands-on group investigations could enhance subject knowledge among students with limited prior exposure to active pedagogical methods.
Out of 250 eligible first-year MBBS students, 40 initially consented to participate, while five subsequently withdrew due to curriculum workload concerns. The final analyzable cohort comprised 30 females and five males with a mean age of 18.35 years. Participants were divided into 10 project groups via lottery to investigate topics in exercise physiology over a one-month period, dedicating three to four hours weekly to their assignments.
Pre-Assessment Scores Rise Following Group Investigations
Students completed a 10-item short-answer pre-assessment carrying a maximum score of 20 before starting their projects. Baseline knowledge yielded a mean score of 5.265 points, representing 26.3 percent of the maximum possible score. Following the one-month intervention, post-assessment scores rose to a mean of 12.588 points, or 62.9 percent of the maximum. Paired-samples t-testing revealed a statistically significant mean improvement of 7.324 points.
Investigators utilized identical assessment questions for both pre- and post-testing. While Shapiro-Wilk testing confirmed normal distribution of the scores, the authors noted that the single-group observational design and lack of a concurrent control group prevent direct causal attribution to the teaching method alone. Practice effects and self-selection bias among the 14 percent of eligible students who chose to participate may have influenced the outcome.
Game-based projects improve medical student grades
Thirty-two participants completed a structured feedback questionnaire utilizing a five-point Likert scale to rate their experience.
In a separate study approach examining sophomore medical students, 148 students developed cardiorespiratory and metabolic physiology projects using board games, card games, and video interviews, resulting in collaborative group grades that significantly exceeded individual test scores.
Frequently Asked Questions About the Muscle Physiology Study
What specific topics did the student project groups investigate?
The 10 project groups examined fatigue during isotonic versus isometric exercise with or without venous occlusion, post-exercise recovery kinetics, cardiovascular and respiratory adaptations, neurocognitive effects of physical activity, and maximal oxygen consumption calculations.
What was the demographic breakdown of the final participant cohort?
The final analyzable cohort of 35 students at the Tamil Nadu institution included 30 female participants and five male participants, representing 85.7 percent and 14.3 percent of the group respectively, with a mean age of 18.35 years.
What limitations did the study authors identify regarding the educational outcomes?
The researchers noted that the single-group observational design, self-selected sample, and use of identical pre- and post-assessment questions preclude causal claims, suggesting that testing-practice effects and positive selection bias may have contributed to the score increases.
