Abstract

The development of Technology and Information is running so rapidly. The technology is not only intended to facilitate human work but also intended to facilitate humans in teaching and learning.  One technology that is widely used to help facilitate human work, especially in the field of statistics, is the SPSS (statistical program for social science) application.  The use of this application in learning statistics courses is absolutely necessary to help make it easier for students to process data at the time of completing the final project. This study is an experimental study with a population of all students who contract statistics courses. Based on the results of the data analysis conducted, the numbers 2,98 > 1,97 were obtained (the t-count value is greater than the t-table value).  Based on the results of the analysis, the hypothesis (Ha) is accepted and the hypothesis (Ho) is rejected.  Because the t-count value is greater than the t-table, the results of this study can be concluded that there is an influence on utilizing the SPSS application on improving students' skills in processing statistical data.

Abstract

The Problem Based Instruction (PBI) learning model is a learning approach that uses real world problems as a context for students to learn how to think critically, problem solving skills, and to gain essential knowledge and concepts from the subject matter. This model is based on constructivist understanding and was developed to help students develop various skills. Mathematical problem solving ability is a component of ability that students must have in learning mathematics. One effort to address the problem of mathematical problem solving ability is through selecting a learning model. The Problem Based Instruction (PBI) model is a learning model that is based on many problems that require real investigation of real problems. This research aims to investigate differences in mathematical problem solving abilities between students who take part in learning using the Problem Based Instruction (PBI) model in junior high school students. This research is a Quasy Experimental research. Data analysis was carried out using the t-test for hypotheses 2 and 4, the t-test for hypothesis 1 and the Mann Whitney U test for hypothesis 3. The hypothesis results show that for the first hypothesis the tcount is more than ttable, for the second hypothesis the tcount is more than ttable, and for the third hypothesis, tcount is less than ttable, and for the fourth hypothesis, tcount is more than ttable. Based on the results of this research, it can be concluded that overall there is a difference in mathematical problem solving abilities between students who take part in learning using the Problem Based Instruction (PBI) model and students who take part in conventional learning among junior high school students. The results of this research can be used to improve students' mathematical problem solving abilities.

Abstract

Penelitian ini bertujuan untuk mengetahui mengetahui keefektivan model pembelajaran Problem Based Learning terhadap kemampuan numerasi matematis siswa kelas VIII SMP Negeri 2 Muara T. A 2023/2024. Penelitian yang digunakan adalah kuantitatif, jenis penelitian ini adalah Penelitian Quasi Experiment. Populasi dalam penelitian adalah seluruh siswa kelas VIII SMP Negeri 2 Muara yang terdiri dari 3 kelas. Dari populasi tersebut, yang menjadi sampel dalam penelitian ini adalah kelas VIII-A dan kelas VIII-B yang dianggap memiliki kemampuan awal yang sama. Dengan menggunakan teknik Cluster Random Sampling maka diperoleh sampel penelitian sebagai kelas eksperimen (VIII-A) sebanyak 26 orang siswa dan sebagai kelas kontrol (VIII-B) sebanyak 24 orang siswa. Instrumen yang digunakan adalah tes dan observasi. Setelah dilakukan penelitian diperoleh hasil t hitung 0,000 pada kemampuan numerasi matematis menunjukkan bahwa nilai Asymp.Sig (2-tailed) sebesar 0,000 < 0,05 pada taraf signifikansi 5% yang berarti ada perbedaan model pembelajaran PBL dengan pembelajaran konvensional. Untuk mengetahui keefektivan model PBL dilihat dari indikator efektivitas yaitu kualitas pembelajaran, kesesuaian tingkat pembelajaran dan waktu. Kualitas pembelajaran dilihat dari daya serap perseorangan, daya serap klasikal dan uji t. Berdasarkan daya serap perseorangan yang menggunakan model PBL terdapat 24 orang siswa yang tuntas dengan nilai diatas 70 dan 2 orang siswa yang tidak tuntas dengan nilai dibawah 70. Berdasarkan daya serap klasikal, untuk persentase ketuntasan klasikal adalah 92,30% dengan kategori sangat tinggi. Hasil lembar observasi kesesuaian tingkat pembelajaran diperoleh skor 4,2 yang berarti keseusaian tingkat pembelajaran sudah baik, pencapaian waktu ideal 4,5 yang berarti baik. Maka dapat disimpulkan model pembelajaran Problem Based Learning efektif terhadap kemampuan numerasi matematis siswa pada materi SPLDV kelas VIII SMP Negeri 2 Muara T. A 2023/2024.

Abstract

This study aims to determine the effectiveness of the GeoGebra learning medium on students’ conceptual understanding and mathematical problem-solving skills regarding the topic of systems of linear equations with three variables in the 10th grade at Budi Setia Private Vocational High School. This study employed a quantitative method using a quasi-experimental design in the form of a pretest-posttest-only control group design. The study population consisted of all Grade 10 students at Budi Setia Private Vocational High School, comprising 5 classes. The sample was determined using purposive sampling, resulting in Class X TKR as the experimental class (30 students) and Class X MP as the control class (30 students). The research instrument consisted of an essay test that had been validated for validity and reliability. Pre-test and post-test data were analyzed using normality tests, homogeneity tests, t-tests, N-Gain, and Effect Size. Calculations for the experimental class showed an average score of 77.80 for mathematical concept comprehension, while the control class had an average score of 68.07. Calculations for the experimental class showed an average score of 73.63 for mathematical problem-solving ability, while the control class had an average score of 66.73. Based on the t-test results, a significance value of 0.001 0.05 was obtained, so the null hypothesis was rejected. The GeoGebra learning tool was found to be effective because it was proven to significantly improve student learning outcomes, as evidenced by a comparison of average post-test scores between classes that used the tool and those that did not. In terms of mathematical concept comprehension, students in the experimental class taught using GeoGebra achieved an average score of 77.80, far surpassing the control class, which averaged only 68.07. This advantage was also consistently evident in the mathematical problem-solving ability indicator, where the experimental class recorded an average score of 73.63, while the control class lagged behind at 66.73. The conclusion of this study is that the GeoGebra learning medium is effective in enhancing students’ mathematical conceptual understanding and problem-solving abilities regarding the topic of systems of linear equations with three variables in Grade 10 at Budi Setia Private Vocational High School.
