This study aims to investigate the relationship between prospective teachers' STEM awareness and information communication technology usage levels. Additionally, according to some demographic characteristics of prospective teachers, it has been determined whether there are differences between STEM awareness levels and information communication technology (ICT) usage levels. The research was carried out with prospective teachers studying at education faculty of a state university in the northwest of Turkey in four programs (science, mathematics, computer education and instructional technologies, classroom teaching). In order to measure the STEM awareness levels of prospective teachers, "STEM Awareness Scale", which was developed by Buyruk and Korkmaz (2016a). In order to determine the information and communication technology usage levels of the prospective teachers, "Information and Communication Technology Usage Levels Scale'', which was developed by Kutluca, Arslan and Özpinar (2010) were used. According to the results obtained in the study, it has been determined that the STEM awareness levels of prospective teachers were positive, the ICT usage levels were moderate, and there was a positive, weak and significant relationship between their STEM awareness levels and ICT usage levels. In addition, the STEM awareness levels and ICT usage levels of the prospective teachers differ in terms of gender, year of study and department.
