This paper aims to describe an innovative Teacher Professional Development Program (TPDP) to develop pre-service mathematics teachers’ curriculum knowledge. The participants of this study were eighteen pre-service mathematics teachers who have not learned about curriculum as a course in their teacher education program. Two different instruments to measure Pre-Service Teacher Curriculum Knowledge in the domain of statistics and algebra were delivered before and after the TPDP. The innovative TPDP for pre-service teachers in this study considered the current school mathematics curriculum as an entry object of learning. Furthermore, the triangle object such as the development of curriculum among countries, essential mathematics content, as well as designing lessons were elaborated in the model. The developed TPDP and pre-service teachers' lesson designs were described and analyzed qualitatively to see the pre-service teachers' curriculum knowledge. The result of the study shows that there is an improvement in Pre-Service Teachers' Curriculum Knowledge in almost all the components of Curriculum Knowledge, except basic skills and concepts. This implies that for designing a lesson plan, pre-service mathematics teachers need to carefully understand the school mathematics structure as a whole in a brief before the basic competence is reviewed.

The research aims to describe students’ verbal mathematical communication skills in solving sequence and series problems, considering their visual, auditory, and kinesthetic learning style. The study addresses the issue that many students still struggle to express their thoughts on sequence and series problems. A qualitative approach is employed in this study, focusing on grade XI students who exhibit a dominant visual, auditory, and kinesthetic learning style. Data collection methods include a learning style assessment, a prerequisite test, and both oral test and written tests on mathematical problem-solving. Results from the oral and written tests are analyzed to characterize each student’s verbal and written mathematical communication. Findings indicate that visual students struggle to verbally communicate mathematical ideas but are able to provide solutions and conclusions. Auditory learners, who excel at learning through listening, meet all indicators, effectively communicating mathematical ideas, presenting solutions, and making conclusions. Meanwhile, kinesthetic learners face challenges to satisfy one of the indicators, namely making conclusions but able to communicate mathematical ideas and provide the solution in their preferred way.

Although Kurikulum Merdeka encourages active and project-based learning, many teachers have difficulty compiling appropriate student worksheet. To overcome the difficulties experienced by teachers, it is necessary to conduct research on the development of student worksheet to be used as a reference by teachers. This study aims to describe the development process and the results of the validity, practicality, and effectiveness of RME student worksheet for the Pythagorean theorem. This development research uses the research design of ADDIE (Analysis, Design, Development, Implementation, and Evaluation). Student worksheet was developed based on iceberg activities designed at the design stage. The ‘situational’ level solves the problem of the square tangram context, the ‘model of’ level constructing a right triangle from several square pieces and identifying its area, the ‘model for’ level determining the length of the sides of a right triangle, and the ‘formal’ level formulating the concept and formula of the Pythagorean theorem. The Realistic Mathematics Education approach is crucial in learning as it presents problems closely related to students' lives, helping them understand faster. This aligns with the Kurikulum Merdeka;s goal of using student-based experiential learning.. Validation was carried out by three validators, then the student worksheet was tested on 30 students of class VIII of SMP Negeri 24 Surabaya. The data collected included learning implementation data, student responses, and pre-test post-test. The validation results show that the student worksheets reached the very valid criteria with a score of 4.4048. The practicality of student worksheet based on the results of the learning implementation data analysis reached the very practical criteria with an average percentage of 94.79% and student responses reached the practical criteria with a total average of 80.20%. The effectiveness based on the N-gain score of student learning outcomes reached moderate criteria with a score of 0.49. This student worksheet focuses on a fun and familiar learning process through paper crafting activities, with students responding positively to it. Thus, the RME student worksheet for the Pythagorean theorem is proven to be valid, practical, and effective.

Mathematics education needs to be taught meaningfully using problem contexts and facilitating reasoning, modeling, collaboration, and connection with other mathematical concepts. This community service project aimed to train primary school teachers in developing Realistic Mathematics Education (RME) 'icebergs' utilizing the local cultural context of Magetan. Twelve primary school teachers in Magetan participated in the RME training, which focused on developing the RME 'icebergs' through exploratory and contextual approaches. The research method included face-to-face sessions, group discussions, and individual tasks to design relevant learning materials. The training results showed significant improvement in the understanding and application of RME. Before the training, teachers faced challenges in engaging students in grades 4-6 and in using local context in mathematics teaching. Post-training, 67% of the teachers demonstrated a positive change in their teaching approach, shifting from lecture and drill methods to an RME-based approach. Additionally, 50% of the participants successfully developed RME icebergs that integrated problems within the local cultural context of Magetan. The training evaluation indicated that over 50% of participants responded positively, showing increased knowledge about realistic mathematics and the application of culturally contextualized problems. The conclusion of this study asserts that the RME approach, especially when combined with local cultural context, is effective in enhancing mathematics teaching skills and enriching numeracy literacy among primary school teachers. The implications of this research suggest integrating RME into the primary school mathematics curriculum to develop critical thinking, creativity, and collaboration skills in students, in line with the demands of the 21st century.
