"High-quality cardiopulmonary resuscitation (CPR)" and "early defibrillation" are the most important parts of "the chain of survival", and they are highly associated with the survival rate and life quality of patients with cardiac arrest. It needs the witness to perform bystander CPR and use the automated external defibrillator (AED) if CPR and defibrillation are expected to be performed earlier. Nevertheless, few patients with cardiac arrest received bystander CPR in Taiwan. It might be caused by some reasons. First, traditional training programs were inefficient and ineffective in the retention of skills and thus students were not confident in their CPR skills after receiving training programs. Second, the current training module focused on personal skill training only and lacked teamwork skills training. It led to poor performance of the students in actual resuscitation scene, where on-scene resuscitators were usually more than one. Third, the current training contents did not improve the attitudes and willingness of performing bystander CPR and it caused people who had received training program did not resuscitate the patients finally. To improve the above-mentioned problem, a three-year research project will be implemented. The aims of the project are the following:
