Model United Nations (MUN) is a formal activity for youth to have a simulation of the United Nations' assembling. This activity requires formal and academic language proficiency, predominantly in English. Nevertheless, since the terms of the pandemic, there have been several setting changes to MUN Simulation's procedure. The MUN, which is usually established offline and provides the tense and excitement, has been chiefly held in a virtual. Furthermore, this research is established to explore students' perception of the new online setting of MUN for their speaking ability. This research is phenomenological qualitative because it will explore several participants' perspectives in a specific online MUN event. It is a research with purposive sampling in order to collect participants with several experiences in online MUN events. Moreover, interviews and conversations with participants will be implemented as a data collection method.
