Disaster problems in Indonesia are complex. Apart from geographically having a high risk of disaster, community disaster literacy is low. Moreover, innovation in disaster matters is lacking, owing to the lack of 21st century skills. Further, disaster literacy and 21st century skills of prospective science teachers in Indonesia are inadequate. This study assumes that a disaster education model for prospective science teachers must be developed. Therefore, this assumption needs to be proven by conducting a needs analysis before developing the model. This study aimed to analyze the needs for the development of the Problem-Based Learning Cycle-Science, Technology, Engineering, and Mathematics-Disaster (PBLC-STEM-D) disaster education model through a sequential-exploratory research design and thereafter develop the initial model with the analysis, design, and development stages. The results of the study revealed that it is necessary to develop the PBLC-STEM-D disaster education model for prospective science teachers. Therefore, the model was developed conceptually.
