This study aimed to determine the pedagogical content knowledge (PCK) of pre-service teachers in developing CoRes as a support for designing mathematics learning. Data were collected by reviewing documents of CoRes development results by 32 pre-service teachers after analyzing school mathematics learning documents in the form of syllabi and lesson plans prepared by experienced teachers. The analysis of the results of the pre-service CoRes document made by the pre-service teachers is done using descriptive statistics that are by calculating the mean. The results of the data analysis show that 18.8% of the pre-service teachers achieved very good qualification, 56.3% with good qualification, 15.6% with sufficient qualification, and 9.4% with poor qualification. Although there were still pre-service teachers belonged to the poor qualification, there were no pre-service teachers who failed in developing CoRes. Some individual students still seem to have difficulty developing CoRes. However, the CoRes document that has been prepared is very useful for carrying out further activities. Thus, it can be concluded that the development of CoRes can be used by pre-service teachers as a support to design learning.

Purpose – Mathematical connection ability is a high-order thinking skill necessary for linking mathematical concepts across topics, disciplines, and real-life contexts. Preliminary observations suggest that many students struggle to establish these connections, particularly when learning the Pythagorean Theorem. Methodology – This study employed a qualitative descriptive research design using a case study method. The sample consisted of 22 students, with four participants purposively selected to represent varying levels of mathematical connection ability. Data were collected through a six-item written test developed based on NCTM indicators and supported by semi-structured interviews for triangulation. Data were analyzed qualitatively to identify patterns in students' mathematical connection performance. Findings – The study found that students generally demonstrated high levels of mathematical connection ability, with a mean score of 70.26%. Most students were able to connect mathematical concepts across different topics and disciplines. However, they encountered difficulties in applying mathematical ideas to real-life situations. These findings highlight the gap between theoretical understanding and practical application. Novelty – This study contributes to the literature by providing in-depth insights into students’ levels of mathematical connection ability, particularly in contextual problem-solving involving the Pythagorean Theorem. Significance – The findings are beneficial for mathematics educators, curriculum designers, and educational policymakers to enhance instructional strategies and support applied mathematical thinking in students.
