Abstract

This study aims to see how the mathematics learning outcomes of class VIII Binsus (Special Guidance) B students of Muhammadiyah 2 Pekanbaru Middle School use the MURDER cooperative learning model. This study uses the classroom action research (CAR) method through two cycles, each cycle consisting of four stages, namely: Planning Stage, Acting Stage, Observation Stage, and Reflection Stage. The subjects of the study were Class VIII Binsus B of Muhammadiyah 2 Pekanbaru Middle School with a total of 22 students consisting of 11 male students and 11 female students. Data in this study were collected through observations of Teacher & Student Activity Observation Sheets and Mathematics Learning Outcomes Tests. The results of the study indicate that the application of the MURDER cooperative learning model can improve students' mathematics learning outcomes. This can be seen from the increase in the average value of student learning outcomes and the percentage of classical completeness from the basic score to cycle I and from cycle I to cycle II. The average learning outcomes before being given action on the basic score only reached an average value of 71% with a classical completeness of 45%. The average learning outcomes after being given action in cycle I for daily test I experienced an increase above the basic score, namely the average value reached 74% with a classical completeness of 68%. In cycle II daily test II, the average student learning outcomes after being given action also experienced a higher increase than the daily test I in cycle I, namely the average value reached 81% with a classical completeness of 77%. Thus, it can be concluded that the application of the MURDER cooperative learning model is effective in improving the mathematics learning outcomes of class VIII B students of SMP Muhammadiyah 2 Pekanbaru.

Abstract

Mathematical problem-solving skills are an essential competence for pre-service mathematics teachers, as they are expected to cultivate these skills in their future students. This study aims to describe the problem-solving profiles of pre-service mathematics teachers using Polya’s four stages as an analytical lens. A qualitative case study approach was employed to examine the cognitive processes demonstrated by pre-service teachers while solving mathematical problems. The findings reveal diverse problem-solving profiles, including conceptual understanding shaped by prior experience, logical reasoning used to interpret problem conditions, and the ability to represent problems through mathematical models. These profiles underscore the need for dedicated coursework that enhances mathematical problem-solving skills within mathematics education programs. The study provides insights into the variation of problem-solving profiles and offers implications for curriculum development in the mathematics education department. Keywords: Mathematical problem-solving skills, pre-service mathematics teachers, Polya’s profile, qualitative research

Abstract

This study aims to analyze number recognition material (0–10) in Indonesian first-grade mathematics textbooks under the Kurikulum Merdeka using a praxeological lens from the Anthropological Theory of the Didactic (ATD). The research method employed was qualitative document analysis of the official textbook published by the Ministry of Education’s Center for Curriculum and Educational Standards. Through this method, the researchers examined tasks (T), techniques (τ), technology (θ), and theory (Φ) to identify epistemic structures and potential learning obstacles embedded in the material. Results show that although the macro-organization of the four main task types is reasonable, the micro-level design is weak. Task sequences often disrupt logical learning trajectories and rely heavily on perceptual and operational techniques, with limited progression toward introspective and a priori reasoning. Technological justifications and theoretical underpinnings remain largely implicit, hindering robust conceptual understanding and generating didactical and epistemological obstacles, particularly regarding zero and the distinction between numbers and numerals. Comparisons with textbooks from high-performing systems highlight shortcomings in epistemic framing, representational coherence, and cognitive demand. The study's implications include providing an integrated praxeological–learning obstacle framework and recommending improvements in textbook design, teaching practice, and policy to enhance students’ epistemic access to elementary mathematics.
