After completing a shared and standardized theoretical course on electrocardiography interpretation, participants are randomly allocated to two parallel groups (intervention and control). The intervention group uses an artificial intelligence chatbot based on a large language model (such as ChatGPT) as a teaching assistant to answer their questions, while the control group asks their questions from a physiology resident (traditional method). All conditions are identical for both groups except for the source of responses. The outcomes measured include learning (through a standardized pretest and posttest), satisfaction, and self-confidence (through a researcher-made questionnaire based on a Likert scale). Data will be analyzed using independent t-test, paired t-test, and analysis of covariance (ANCOVA), Randomization description: Eligible participants, after providing informed consent, are allocated completely randomly to either the intervention group (Artificial Intelligence) or the control group (traditional method) using a random number table or random number generation software. The sample size in each group is 35 participants. N/A Electrocardiography Interpretation Education. Intervention group:. No - There is not a plan to make this available Justification or reason for not sharing IPD is Individual participant data, including educational information and student scores, cannot be publicly shared due to confidentiality and ethical principles in educational research. Publishing such data could lead to indirect identification of students and contradicts the ethical commitments of this study.
