Abstract

This study aims to analyze the influence of classroom discussion activities on the ability to master statistical learning materials in sharia accounting students. The method used in this study is quantitative, with data collection through a questionnaire distributed to 19 respondents. The data analysis technique used is multiple linear regression. The results of the analysis showed that there was a significant positive relationship between class discussion activities and material mastery ability. This study indicates that the application of the discussion method can improve students' understanding of statistical materials, as well as encourage critical and analytical thinking skills. These findings make an important contribution to the development of more effective learning strategies in the academic environment.

Abstract

This study aims to analyse the level of students' understanding of concepts in Statistics courses and examine the impact of applying presentation methods in the learning process. The study uses a descriptive approach and was conducted in the Sharia Accounting class in Semester 3 at UINSU Medan in the 2024/2025 academic year. The research subjects were students in class AKS 3B, while the research object was a questionnaire designed to measure students' conceptual understanding of statistics material. The data obtained were analysed descriptively to describe the trends in students' conceptual understanding levels. The results showed that the average level of students' conceptual understanding ranged from 2.41 to 2.71. This range falls within the neutral category, i.e., between 2.1 and 3, indicating that students' conceptual understanding of statistical material through the presentation method is not yet fully optimal and still needs to be strengthened through more varied learning strategie

Abstract

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

Tujuan penelitian adalah untuk mengetahui dengan menerapkan Model Pembelajaran kooperaiif tipe STAD menggunakan LAS pada materi SPLDV dapat meningkatkan hasil belajar siswa kelas VIII SMP Swasta Pembangunan Galang. Jenis penelitian ini yaitu penelitian tindakan kelas (Classroom Action Research). Subjek dalam penelitian ini adalah siswa kelas VIII yang berjumlah 30 orang dan objek dalam penelitian ini adalah pembelajaran menggunakan model pembelajaran kooperatif tipe STAD dengan menggunakan LAS materi SPLDV. Instrumen penelitian yang digunakan adalah tes kemampuan awal, tes uraian sebanyak 10 butir soal. Sebelum menerapkan model pembelajaran kooperatif tipe STAD berbatuan LAS, maka dilakukan tes kemampuan awal siswa untuk mengetahui sejauh mana kemampuan siswa sebelum tindakan. Dari hasil analisis data diperoleh bahwa hasil kemampuan awal siswa diperoleh sebanyak 7 siswa (23,33%) hasil belajar nya tuntas sedangkan sebanyak 23 siswa (76,67%) belum tuntas dengan nilai rata-rata kelas 34,20. Setelah dilakukan tindakan pada Siklus I dikelas diperoleh sebanyak 19 siswa (63,33%) yang hasil belajarnya tuntas sedangkan 11 siswa (36,67%) hasil belajar nya belum tuntas dengan nilai rata-rata 65,2. Kemudian pada siklus II, sebanyak 28 siswa (93,3%) yang hasil belajarnya tuntas sedangkan 2 siswa (6,67%%) belum tuntas dengan rata-rata kelas 91,2. Hasil ini menunjukkan bahwa terdapat peningkatan hasil belajar siswa pada kemampual awal siswa, siklus I, dan siklus II. Kemudian berdasarkan criteria ketuntasan klasiikal maka pembelajaran dengan model kooperatif tipe STAD telah mencapai ketuntasan belajar secara klasikal meningkat. Dengan demikian dapat ditarik kesimpulan penerapan model pembelaaran koopeeatif tipe STAD dengan berbantuan lembar aktivitas siswa dapat digunakan untuk meninggaktakn hasil belajar matematika siswa.

Abstract

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. Keyword: Gander, Mathematical Literacy, Interest in Learning, Digital Trigonometry Module, Problem Based Learning. 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. Penelitian ini merupakan penelitian eksperimen semu dengan sampel penelitian sebanyak 69 siswa dengan kelas X-4 sebanyak 34 siswa sebagai kelas eksperimen dan kelas X-3 sebanyak 35 siswa sebagai kelas kontrol. Data yang diperoleh dari penelitian ini adalah data pretest dan posttest kemampuan literasi matematik siswa dan angket minat belajar siswa. Instrumen yang digunakan untuk mengumpulkan data tersebut adalah tes kemampuan literasi matematik dan minat belajar siswa. Data yang dikumpulkan tersebut kemudian dianalisis dengan menggunakan anava dua jalur pada program SPSS. Berdasarkan hasil analisis data diperoleh bahwa peningkatan kemampuan literasi matematik dan minat belajar siswa yang mendapat pembelajaran berbasis masalah berbantuan modul digital trigonometri lebih tinggi daripada peningkatan kemampuan literasi matematik dan minat belajar siswa yang mendapat pembelajaran biasa. Tidak terdapat interaksi antara model pembelajaran berbasis masalah berbantuan modul digital trigonometri dan gender terhadap peningkatan kemampuan literasi matematik dan minat belajar siswa. Kata kunci: Gander, Literasi Matematik, Minat Belajar, Modul Digital Trigonometri, Pembelajaran Berbasis Masalah.
