The following interventions were applied to the control group;

1. Pretest: A 10-question pretest was administered before the theoretical training to assess students' knowledge levels prior to Advanced Life Support training.
2. Theoretical Training: Following the completion of the pretest, participants received "ERC 2021 Adult Advanced Life Support training" in accordance with the European Resuscitation Council 2021 guidelines in two sessions, one before and one after noon. The training duration was 2 hours.
3. Simulation Training: Five days after the theoretical training, students received simulation training.
4. Post-test, student satisfaction and self-confidence evaluation: After the simulation, students took their post-test and filled out data collection forms including the student satisfaction and self-confidence scale and the teamwork scale.

In the experimental group, unlike the control group, simulation training was supported by microteaching.

Microteaching: Students in the experimental group watched the "Advanced Life Support Team Dynamics Video." The video was uploaded to the university's education management system, and a student monitoring report was generated, ensuring that all students could watch it.

Teamwork was assessed using the Turkish version of the Mayo High Performance Teamwork Scale (MHP-TS). The scale evaluates 16 aspects of team functioning, with each item rated on a 3-point scale: 0 (never), 1 (inconsistent), and 2 (consistent). Total scores range from 0 to 32, with higher scores indicating better teamwork. The scale was administered immediately after the simulation-based advanced life support training supported by microteaching.

Student satisfaction and self-confidence were assessed using the Turkish version of the Student Satisfaction and Self-Confidence in Learning Scale (SSSCLS). The scale includes two subscales: Satisfaction (5 items) and Self-confidence (8 items). Each item is rated on a 5-point Likert scale (1 = strongly disagree to 5 = strongly agree). Higher scores indicate greater satisfaction and confidence. The scale was administered immediately after the simulation-based advanced life support training supported by microteaching.
