Abstract

Penelitian ini bertujuan mengetahui pengaruh model pembelajaran Problem Based Learning (PBL) terhadap kemampuan pemecahan masalah matematis siswa pada materi Statistika kelas VIII. Metode yang digunakan adalah Quasi Experiment dengan desain pretest-posttest control group design. Sampel penelitian terdiri atas dua kelas, yaitu kelas eksperimen berjumlah 31 siswa yang diberi perlakuan dengan model PBL dan kelas kontrol berjumlah 28 siswa yang diajar dengan model konvensional. Instrumen penelitian berupa tes pemecahan masalah matematis berbentuk uraian yang telah diuji validitas dan reliabilitasnya. Hasil penelitian menunjukkan bahwa nilai N-Gain pada kelas eksperimen sebesar 0,73 (kategori tinggi), sedangkan pada kelas kontrol sebesar 0,32 (kategori sedang). Rata-rata nilai posttest siswa kelas eksperimen juga lebih tinggi dibandingkan dengan kelas kontrol. Uji hipotesis menggunakan uji-t menghasilkan nilai thitung = 13,858 > ttabel = 2,8 dengan sig. = 0,000 < 0,05, yang berarti terdapat pengaruh signifikan model PBL terhadap kemampuan pemecahan masalah matematis siswa. Dengan demikian, penerapan PBL dapat dijadikan alternatif yang efektif dalam pembelajaran matematika untuk meningkatkan kemampuan pemecahan masalah siswa

Abstract

This study was conducted to determine the influence of a deep dialogue / critical thinking (DD/CT) learning model on the mathematical reasoning ability of students in class X of high school on opportunity materials at Budi Murni Catholic Private High School – 3 Medan. The type of research used is quantitative using quasi-experimentation with the research design being pretest postest control group design. This study uses 2 classes, namely the control class and the experimental class. The test of the research instruments used in this study are the validity test, reliability test, question differentiating power test and question difficulty level test, to find out whether the question to be tested is feasible or not. The prerequisite tests used are the normality test and the homogeneity test. For the hypothesis test, a t-independent test (α:0.05%) was used with the P criterion. The value must be less than 0.05, so there is a significant difference. The result of the t- independent test obtained was 0.004. The significant difference between the control class and the experimental class that was given different treatment can be concluded that the deep dialogue/critical thinking (DD/CT) learning model has an effect on students' mathematical reasoning skills.

Abstract

This study was motivated by the low level of mathematical problem-solving skills among students at the Jambi Medan Private Vocational High School, which is attributed to the use of conventional teaching methods that do not sufficiently encourage active engagement and deep understanding. The objective of this study is to determine the influence and magnitude of the impact of the Deep Learning approach on the mathematical problem-solving skills of 11th-grade students in matrix material. The research method used is a Quasi-Experiment with a Post-test Only Control Group Design. The research population includes all 11th-grade students, with a sample selected through Cluster Random Sampling consisting of class XI MPLB 2 as the experimental class and XI MPLB 1 as the control class. Data analysis results showed that the average post-test score of the experimental class (72.62) was higher than that of the control class (46.40). Based on the t-test, a significance value of 0.000 0.05 was obtained, indicating a significant effect. The Effect Size test using Cohen’s D yielded a value of 3.29, which falls under the “very large” criterion. Thus, the Deep Learning approach is effective in improving students’ mathematical problem-solving skills at the Jambi Medan Private Vocational High School.

Abstract

This study aims to examine the effectiveness of using GeoGebra based on the Student Teams Achievement Divisions (STAD) model in improving students’ understanding of mathematical concepts in the matrix curriculum for XI-grade students at State SMA Negeri 14 Medan T.A 2025/2026. The method used was quantitative research with a quasi-experimental design. The study population consisted of 11th-grade students, with a sample of 69 students from classes XI 4 and XI 5 selected through purposive sampling. The instruments used included an essay test, a questionnaire, and an observation sheet. The research results indicate that all five indicators of effectiveness were met: (1) the instructional structure was in the “good” category, based on evaluations by two out of three observers, who assigned scores of 86 and 87, respectively; (2) teacher communication was good, with two observers assigning a score of 34; (3) student response was good, as evidenced by 57 out of 69 students falling within the “good” frequency range; (4) student activity was good, with 62 students in the good category according to three observers; (5) learning achievement was complete without remedial instruction, with 58 students (91.3%) scoring in the 66–85% range. Thus, the use of the STAD method with GeoGebra is effective in enhancing students’ understanding of mathematical concepts.

Abstract

This study aims to identify various factors that influence the development of higher-order thinking skills in the Master's program mathematics education department at Universitas HKBP Nommensen. The systematic AHP method allows for accurate weighting and prioritization of various factors influencing HOTS. These results provide a strong foundation for policy recommendations and educational practices aimed at enhancing higher-order thinking skills among outstanding students. The ranking results of the factors influencing HOTS among 100 outstanding students in the Master's program in Mathematics Education were analyzed using the hierarchy of one factor over another. By observing the three criteria and ten sub-criteria, it can be concluded that Criterion 2, or students, is the most influential factor in determining students' HOTS with a weight of 0.53. The second influencing factor is Criterion 1, or lecturers, with a weight of 0.13, and the least influential factor is the learning environment with a weight of 0.07. Matrix interpretation shows that the Lecturer factor (K1) is considered more important than the Student factor (K2) and the Learning Environment factor (K3) in influencing the HOTS of high-achieving students. This highlights how important lecturers are in helping students develop higher-order thinking abilities.

Abstract

This study aims to determine the effect of the Problem Based Learning (PBL) learning model on students' mathematical problem-solving abilities in Statistics material for grade VIII. The method used is Quasi Experiment with a pretest-posttest control group design. The research sample consisted of two classes, namely the experimental class consisting of 31 students who were treated with the PBL model and the control class consisting of 28 students who were taught with the conventional model. The research instrument was a mathematical problem-solving test in the form of descriptions that had been tested for validity and reliability. The results showed that the N-Gain value in the experimental class was 0.73 (high category), while in the control class it was 0.32 (medium category). The average posttest score of students in the experimental class was also higher than that of the control class. Hypothesis testing using the t-test produced a t-value of 13.858 > t-table = 2.8 with sig. = 0.000 < 0.05, which means there is a significant influence of the PBL model on students' mathematical problem-solving abilities. Thus, the application of PBL can be used as an effective alternative in mathematics learning to improve students' problem-solving abilities.
