摘要：The rapid changes in science and technology have changed the traditional education concept by improving the accessibility of information. Current educational understandings require the application of flexible programs that respond to differences in the interests and abilities of the students and that can go into diversity within themselves. One of these approaches is the Science Technology Engineering and Mathematics (STEM) approach. This study aims to explore the effect of STEM based laboratory activities on preservice teachers STEM awareness. The study was conducted in science laboratory practices-I course, which is included in the undergraduate science teacher education program. Quasi-experimental research method was used to investigate the study. Participants were consist of 50 third grade preservice science teachers from Yüzüncü Yıl University Science Teacher Education Department who take the Laboratory Instruction of Science Instruction-I course. FeTeMM awareness scale developed by Buyruk and Korkmaz (2014) was used as data collection tool. Based on the results of the dependent sample t-test scores, STEM-based science laboratory applications increased the experimental group students' awareness of STEM.
