This study aims to support the improvement of prospective middle school mathematics teachers' mathematical knowledge and professional noticing skills on the perimeter concept through the development of the model based on the cycles of enactment and investigation within the framework of design-based research. Data were collected from senior prospective mathematics teachers who are enrolled in one of the sections of the Teaching Practice 2 course in the spring semester of 2020-2021 at one of the state universities in Istanbul. The data obtained from these prospective teachers were analyzed as a group, while the results obtained from one prospective teacher who had perimeter teaching experience in different classroom settings as part of the current study were presented. Multiple data sources were used in the data collection process, such as pre-and post-tests, post-interviews, initial and revised lesson plans, individual responses to classroom activities, videotapes of the model implementations, and field notes. Qualitative methods were used to analyze the data. Findings from the pretest indicated that the prospective teacher lacked mathematical knowledge and professional noticing skills on the perimeter concept prior to participating in the current study. In contrast, the findings obtained from the post-test and post-interview results showed that there were significant improvements in her mathematical knowledge and professional noticing skills on the perimeter concept throughout the study. Based on the findings of this study, it can be argued that the model based on the cycle of enactment and investigation can be used as an effective practical tool to develop preservice teachers' mathematical knowledge and professional noticing skills on the perimeter concept.
