This research aims to identify the effects of a science, technology, engineering, arts and mathematics implementation in the ancient age architecture field on the achievements of the undergraduate students and their science, technology, engineering and mathematics (STEM) perceptions. The research was based on the explanatory design, while the experimental design with pre-test and post-test control groups was carried out in the quantitative component of the study and the case study was carried out in the qualitative component. In the first stage, the study context, selections of the groups, development and implementation of the pre-test and formation of the project groups were realised. The second stage was accomplished by carrying out the study in accordance with the determined plan, implementations of the practices, realising the post-test and conducting the interviews. Finally, a significant difference was observed between the achievement test mean scores of the experimental group and the control group in favour of the experimental group
