This study investigates whether there is a difference in the BLS skills in first year medical students directly after training and three months later, when randomly assigned to self-learning versus instructor-led training courses.
This is a randomized controlled trial investigating whether self-learning versus instructor-led learning results in the same BLS skills in first year medical students directly after training and three months later. When participants attend the "Erweiterte Erste Hilfe für Studierende der Humanmedizin" they will receive a short introduction about the study. The investigators will invite all first year students to participate in the study. As the study is voluntarily, participants need to sign a written informed consent. After that, the investigators will randomize the students to either group A or Group B. Group A will train their technical CPR-skills with supervision by a tutor (either general practitioner or medical student, all trained in CPR teaching) and group B will train without supervision. The participants in group B will not be allowed to communicate with each other during the training and they will be prevented from watching each other. The training will take about 30 minutes for each group. Directly after the training each group will be tested and the printed report form from the Laerdal Skill Reporter will be obtained for each participant. In the test the students will perform CPR in a simulated scenario as a first responder. The scenario is: "A male person has collapsed at the railway station." The participant should start CPR as learned in the training. During the CPR a departmental research fellow will observe the study participants and record BLS/AED actions on a scoring sheet. The investigators will record three cycles of two minutes CPR (with five times 30:2 compression : ventilation intervals, as recommended by the current international resuscitation guidelines). During the three cycles an AED will be delivered and the study participant has to apply the AED and deliver a shock - after three cycles the study terminates. After the BLS/AED competence testing, both groups will continue the rest of their first aid course together and the first part of the study ends. Three months later, the investigators will repeat the same scenario over the same time interval and record the same parameters. At the end of the second testing, a short feedback will be provided on the BLS/AED competence and further practice will be provided to the students to improve their CPR competence. From this point forward no further data will be collected.

Percentage of Correct Compressions
The percentage of correct compressions obtained from the printed report from the Laerdal Skill Reporter.
Time frame: after first BLS course and 3 months later
Assessment of the Participants BLS Competences After Test
Assessment of the participant's BLS competence by the study team after test. Rated on a Visual Analogue Scale from 0-100mm, where 0mm = completely incompetent, no idea what to do, and 100mm = totally competent, cannot be done better.
Time frame: after first BLS course and 3 months later
Self-assessment of the Participants BLS Competences Before Test
The participants assessment of their own BLS competences. Rated on a Visual Analogue Scale from 0-100mm, where 0mm = completely incompetent, no idea what to do, and 100mm = totally competent, cannot be done better.
Time frame: before first BLS course and 3 months later
Assessment of the Teaching Method
The participants assessment of the teaching method. Rated on a Visual Analogue Scale from 0-100mm, where 0mm = completely inefficient, and 100mm = totally efficient, nothing can be done better."
