This research aims to describe the development process and quality of STEM-based mathematics e-comics designed to enhance students’ creative thinking skills in flat-sided geometric materials for eighth-grade students at SMP. The study follows a Research and Development (R&D) approach using the ADDIE development model. The test subjects included a team of experts, a mathematics teacher, and eighth-grade students at SMPN 56 Merangin. The findings indicated a high level of validity, with the e-comics receiving a validity rating of 100% in terms of media and 95,24% in terms of material. The practicality rating from teachers was 100%, and it was classified as very practical. The overall practicality of the e-comics also fell under the “very practical” criteria. The effectiveness of the e-comics, as determined by an effectiveness questionnaire, scored 81,91%, which was considered “very effective.” Furthermore, a test yielded an N-Gain score of 0,65 categorizing the e-comics as quite effective. Based on the N-Gain score, it can be concluded that STEM-based mathematics e-comics effectively improve students’ creative mathematical thinking abilities.

This research aims to describe students spatial abilities based on cognitive load theory in geometry learning. This research approach is a qualitative approach and the type of research is descriptive research. The data obtained in this research includes qualitative data obtained from observation sheets, tests, interviews and documentation. To check the validity of the data using the data triangulation method. The subjects in this research were students of class XII Science 3 SMA Negeri 13 Jambi City. The research results showed that students' spatial abilities were still low and there was a cognitive load on students. The cognitive load that arises in learning can be seen from the complexity of the material studied, media, methods and learning strategies used by the teacher. To improve students' spatial abilities, teachers can design learning with appropriate media, methods and strategies so as to minimize the cognitive load on students.
