Purpose. Teaching ABCDE is elaborated by simulation based medical education (SBME). However, high level of physical and environmental fidelity of SBME, psychological fidelity is not necessarily optimal according to the literature. The term psychological fidelity means that educational situation stimulates the same psychological processes that appear in real clinical situations (1). To achive this goal our team has elaborated a new methodology named drama and simulation based medical education (DSBME) (2). DSBME method reframes the educational sitation: it
removes the instructor role without moving his/her knowledge from the situation. Apperent contradiction is solved by the technic of so called „inner voice”, which is known from the drama methodology.
Materials and methods. Effects of the new methodology will be assessed by a study designe to measure elements of psychological fidelity. A within-subjects experiment with 54 undergraduate medical university students divided into groups of 4 members will be carried out. Participants will randomly be assigned to the methodology SBME vs. DSBME, the different scenarios and team roles. 
Hypothesis Measurement
1. both team leaders and team members shows higher electrodermal activity (EDA) at DSBME EDA measuring by open-source biomonitor (obimon.com)
2. team members will produce higher synchronicity with each other during team performance at DSBME detailed analysis of AV-recorded
performance (3)
3. all students will show higher involvement at DSBME as compared to SBME measuring involvement by a flow survey (4)
As final results will not be available by the time of the conference, in our presentation we propose introducing our new methodology (DSBME) and the study design.
