“Gastrointestinal Circuit”: an active learning approach to enhance understanding of human digestive system physiology

The "Gastrointestinal Circuit" is a practical and accessible active learning strategy that improves undergraduate understanding of gastrointestinal physiology. Using visually engaging vinyl banners, it helps clarify complex concepts. Students showed significant knowledge gains from pre- to posttest, and those who participated in the circuit outperformed a previous cohort who did not engage in the activity. These results support the circuit as an effective tool for enhancing learning in physiology education.
