The developed instructional model was a blending of e-briefing with face-to-face role-play simulation and debriefing. The aim of this study was to improve the effectiveness of the developed instructional model. This study employed a formative evaluation by Tessmer (2013) with used both qualitative and quantitative approaches. The respondent of field test is 22 students of the 2016-2017 academic years. The formative evaluation was consisted of expert review, one-to-one, small group, and field test. This research was carried out at Indonesia Civil Aviation Institute. The data were collected through open-end interview, questionnaire, and field observation. The data analysis used descriptive statistic method. The finding indicates that the blended learning simulation based model increased learning outcome (+12.55); students and instructors were more satisfy when they implemented this model (4.47); and the model increased student's attention level (4.5). Based on the findings, the proposed instructional model can be implemented in this institution. http://pubs.sciepub.com/education/5/11/1/education-5-11-1.pdf blended learning simulation instructional model
