Real life jobs need interdisciplinary skills and educations should be adjusted in a way that students obtain these skills in their education lives. Designing interdisciplinary online courses seems to be unavoidable in educational institutions to have the technological and innovational catch-up in the 21st century. Unique Science, Technology, Engineering, Arts and Math (USTEAM) not only has the intellectual facilities, but helps students to achieve their confidence and encourages them to participate. This paper includes a literature review about the effect of culture on students' academic behaviors as well as statistical results about students' perception and attitude to the USTEAM approach. In the online courses by fostering creativity, collaboration, critical thinking, and communication and applied approach students are encouraged to love and participate in online learning. At the end of 4 months online course period, students' success is measured in three factors with BWG Assessment: Behavioral Success, Work Success and Group Success. IBM SPSS Statistics 25 used for reaching conclusions and for interpreting the data obtained. There were significant differences between males and females. Although some students were aggressive at the beginning toward being a member of STEAM, they were more motivated when they didn't had any competitors and they were expected to produce their Unique projects regardless of what others do! For motivation theorists, the results from this study provide evidence that interdisciplinary cultural influences in courses can be expressed in diverse educational settings. For educators, this study underlines the importance of cooperative and creative USTEAM activities in online courses.
