Mathematics learning trajectory is one of the key concepts in student-centered mathematics learning design. This article aims to analyze and describe the development of Hypothetical Learning Trajectory (HLT) as a framework for designing effective mathematics learning at the Junior High School level. The method used is design research with a qualitative approach through three phases: preparation phase, experimentation phase, and retrospective analysis phase. Research subjects consisted of 32 seventh-grade students at SMP Negeri 37 Medan. Research instruments included observation sheets, concept understanding tests, and semi-structured interviews. The results showed that HLT-based learning significantly improved students' conceptual understanding of integer material, with average scores increasing from 58.4 to 81.7. In addition, student learning motivation increased as demonstrated through the level of active participation in learning activities. The conclusions of this study confirm that systematic and reflective HLT development has great potential as an innovative strategy in meaningful and student-centered mathematics learning.

Abstract: This research aims to identify the increase in students' mathematical literacy skills and interest in learning after using problem-based learning assisted by digital trigonometry modules, as well as to see the interaction between problem-based learning assisted by digital trigonometry modules and gender on increasing students' mathematical literacy abilities and interest in learning. This research is a quasiexperimental research with a research sample of 69 students with class X-4 as many as 34 students as the experimental class and class X-3 as many as 35 students as the control class. The data obtained from this research are pretest and posttest data on students' mathematical literacy abilities and a questionnaire on students' learning interest. The instruments used to collect this data were tests of students' mathematical literacy skills and interest in learning. The collected data was then analyzed using two-way ANOVA in the SPSS program. Based on the results of data analysis, it was found that the increase in mathematical literacy skills and interest in learning for students who received problem-based learning assisted by digital trigonometry modules was higher than the increase in mathematical literacy skills and interest in learning for students who received regular learning. There is no interaction between the problem-based learning model assisted by digital trigonometry modules and gender on increasing students' mathematical literacy skills and interest in learning.Â Keyword: Gander, Mathematical Literacy, Interest in Learning, Digital Trigonometry Module, Problem Based Learning.Â Abstrak: Penelitian ini bertujuan untuk mengidentifikasi peningkatan kemampuan literasi matematik dan minat belajar siswa setelah menggunakan pembelajaran berbasis masalah berbantuan modul digital trigonometri, serta untuk melihat interaksi antara pembelajaran berbasis masalah berbantuan modul digital trigonometri dan gender terhadap peningkatan kemampuan literasi matematik dan minat belajar siswa.

Abstract: This study examines in depth the integration process using the "Tolu Sahundulan" philosophy in the topic of triangular angles and analyzes its influence on students' creative thinking skills. Creative thinking ability is an essential competency that needs to be developed in mathematics learning to equip students with innovative problem-solving skills. Conventional methods are often inadequate in stimulating student creativity. Therefore, this study explores the potential of the Tolu Sahundulan method which is assumed to offer a more active and exploratory learning approach. This study uses a qualitative approach with students involved in learning triangular angles using the Tolu Sahundulan philosophy. Data were obtained through classroom observations, in-depth interviews, and analysis of student work. The results of the analysis show that the integration of Tolu Sahundulan in learning triangular angles significantly encourages students to explore concepts more deeply, produce various solution strategies, and show improvements in thinking flexibility and originality of ideas. These findings confirm that Tolu Sahundulan can be an effective alternative learning method for improving students' creative thinking skills in mathematics. Implications of this research include recommendations for educators and curriculum developers to adopt student-centered and creativity-stimulating learning methods. Keywords: Tolu Sahundulan, Creative Thinking Ability in Mathematics, Triangle Angles Abstrak: Penelitian ini mengkaji secara mendalam proses integrasi menggunakan falsafah "Tolu Sahundulan" dalam materi sudut segitiga serta menganalisis pengaruhnya terhadap kemampuan berpikir kreatif siswa. Kemampuan berpikir kreatif merupakan kompetensi esensial yang perlu dikembangkan dalam pembelajaran matematika guna membekali siswa dengan keterampilan pemecahan masalah yang inovatif. Metode konvensional seringkali belum memadai dalam menstimulasi kreativitas siswa. Oleh karena itu, penelitian ini mengeksplorasi potensi metode Tolu Sahundulan yang diasumsikan menawarkan pendekatan pembelajaran yang lebih aktif dan eksploratif. Penelitian ini menggunakan pendekatan kualitatif dengan subjek siswa yang terlibat dalam pembelajaran sudut segitiga menggunakan falsafah Tolu Sahundulan. Data diperoleh melalui observasi kelas, wawancara mendalam, dan analisis karya siswa. Hasil analisis menunjukkan bahwa integrasi Tolu Sahundulan dalam pembelajaran sudut segitiga secara signifikan mendorong siswa untuk mengeksplorasi konsep secara lebih mendalam, menghasilkan berbagai strategi penyelesaian, dan menunjukkan peningkatan dalam fleksibilitas berpikir serta orisinalitas ide. Temuan ini menegaskan bahwa Tolu Sahundulan dapat menjadi alternatif metode pembelajaran yang efektif untuk meningkatkan kemampuan berpikir kreatif siswa dalam matematika. Implikasi penelitian ini mencakup rekomendasi bagi para pendidik dan pengembang kurikulum untuk mengadopsi metode pembelajaran yang berpusat pada siswa dan stimulatif terhadap kreativitas.

This study examines the effects of implementing Problem-Based Learning (PBL)-based worksheets integrated with Batak culture on students’ mathematical critical reasoning skills. A quantitative approach was used with a one-group pretest-posttest pre-experimental design. The research subjects were students in class XI-1 at SMAN 1 Air Putih, selected through purposive sampling. Data collection was conducted using an essay test. The analysis included a paired t-test, a normality test, and an N-gain analysis. The results showed that the data were normally distributed (pretest 0.293; posttest 0.356). The t-test yielded a significance level of 0.001 (<0.05), indicating a significant effect. The N-gain value of 0.67 falls into the moderate category, indicating an improvement in ability. Thus, PBL-based worksheets integrated with Batak culture are effective in developing students’ mathematical critical reasoning.

This study was conducted to examine the effect of using LAPS Heuristic-basedE-LKPD on students’ learning outcomes. The research applied a quantitative approachwith a pretest-posttest design. The sample of this study consisted of 36 students. Datawere collected through a pretest administered before the implementation of the E-LKPDand a posttest conducted after the implementation of the LAPS Heuristic-based E-LKPD.The obtained data were analyzed using a paired sample t-test to determine the differencesin learning outcomes before and after the treatment. The findings revealed that theaverage pretest score was 69.36, while the average posttest score increased to 92.47. Thestatistical analysis showed that the value of ???????????????????????? = 14.37, whereas the value of???????????????????????? = 2.03at the 5% significance level. Since the value of ????????????????????????was higher than????????????????????????, H₀ was rejected and H₁ was accepted. These results indicate that the use of LAPSHeuristic-based E-LKPD had a significant effect on improving students’ learningoutcomes. Therefore, the LAPS Heuristic-based E-LKPD was considered effective for usein the learning process.
