<![CDATA[This study aims to determine the effect of problem-based learning models on students' Pythagorean theorem problem solving ability. This research was carried out at SMPN 1 Suralaga for the 2023/2024 school year. The type of research used is a quasi experiment. The population in this study were class VIII students of SMPN 1 Suralaga for the 2023/2024 academic year. The sample was 44 students consisting of 22 experimental class students and 22 control class students. The data collection techniques used are observation and tests. While the research instrument consists of observation sheets, problem-solving ability test sheets, lesson implementation plans and student worksheet. Data taken with t-test, obtained acceptable results accepted, there is a difference in the problem-solving ability of the Pythagorean theorem in students whose learning used the problem-based learning model with students who used the direct learning model. The average posttest result for the experimental class was higher than the control class, namely 82.41>75,00. This shows that there is an influence of the problem based learning model on the Pythagorean theorem problem solving abilities of class VIII students at SMPN 1 Suralaga using the effect size test, obtained d=0.67, which means the influence given is in the medium category.]]>

<![CDATA[This research aims to know the influence of using visual animation media on students' learning outcomes in mathematics education. The research design employed is quantitative research with an experimental method. The design used in this study is quasi-experimental design. Data collection techniques include tests and observations. The test instrument consists of 5 essay questions used to assess students' learning outcomes and observation guidelines are used to gather desired data based on the research objectives. The population of this study is all eighth-grade students, totaling 196 students. The sampling technique used in this study is cluster random sampling. Class VIII-A with 29 students is the sample group that uses animation media in their learning (experimental class), while Class VIII-B with 28 students is the sample group that learns without animation media (control class). The data analysis techniques used include normality and homogeneity tests as prerequisites, and the t-test as the hypothesis test. Based on the hypothesis test results using the t-test at a significance level of 5%, the obtained value of t-value is 2,068 and t-table is 2,004. Since the value of tvalue > ttable, so the null hypothesis H0 is rejected, indicating that there is an influence in the use of visual animation media as a mathematics learning media on students' learning outcomes.]]>

This research is an experimental research with quasi experimental design. The study population was the XI grade students of SMK Negeri 3 Selong as many as 4 classes. The research sample was two classes, namely the experimental class using Canva-based learning media and the control class using conventional media taken using cluster random sampling. Data collection techniques using observation and tests. As for the instrument validity test, it was carried out with the content validity test which was calculated using the Aiken's V index. Data analysis carried out is normality test, homogeneity test, hypothesis test, and effect size test to see whether there is an effect of Canva-based learning media on student learning outcomes on circle material. The results showed t_hitung (2.661) > t_table (2.01), the effect size test results were 0.757 and the average value of the posttest results of the class using Canva-based learning media was higher than the class using conventional media. So it can be concluded that learning by using Canva-based learning media has an effect on student learning outcomes in circle material class XI SMK Negeri 3 Selong academic year 2024/2025.]]>

<![CDATA[This study aims to analyze the factors that cause low interest in learning mathematics in students at MA Plus Nurul Islam Sekarbela and explore efforts that can be made to overcome these factors. This study uses a qualitative descriptive method with data collection techniques in the form of observation, interviews, and documentation. The results of the study indicate that the level of student interest in learning varies, where some students show a high interest in mathematics, while others have difficulty understanding the material so that they are less motivated. Factors that inhibit interest in learning include difficulty in understanding complex material, limited learning time, lack of additional learning resources, less interesting teaching methods, and minimal use of technology in learning. The conclusion of this study shows that to increase interest in learning mathematics, it is necessary to use technology-based media, contextual and project-based learning approaches, and provide additional learning resources. The implementation of this strategy is expected to increase student involvement and motivation in learning mathematics at MA Plus Nurul Islam Sekarbela]]>

<![CDATA[Penelitian ini bertujuan untuk mendeskripsikan jenis-jenis kesalahan siswa dalam menyelesaikan masalah pada materi penyajian data ditinjau dari gaya belajar siswa kelas VIII semester ganjil di SMPN 17 Mataram tahun ajaran 2024/2025. Metode penelitian yang digunakan adalah deskriptif kualitatif. Populasi penelitian berjumlah 139 siswa, dan sampel penelitian sebanyak 104 siswa yang diambil menggunakan teknik Proposional Sampling berdasarkan rumus Slovin. Subjek penelitian terdiri dari 9 siswa yang dipilih untuk dianalisis lebih mendalam. Pengumpulan data dilakukan melalui kuesioner untuk mengidentifikasi gaya belajar, tes tertulis untuk menganalisis kesalahan, serta wawancara untuk mendalami penyebab kesalahan. Teknik analisis data mencakup identifikasi gaya belajar dan identifikasi kesalahan penyelesaian masalah. Hasil penelitian menunjukkan bahwa siswa dengan gaya belajar visual cenderung melakukan 2 jenis kesalahan dari 5 jenis kesalahan Newman yang dilakukan siswa yaitu process skill dan encoding. Sedangkan gaya belajar auditorial cenderung melakukan kesalahan pada jenis transformation, process skill, dan encoding. Sementara itu, siswa dengan gaya belajar kinestetik cenderung melakukan kesalahan pada jenis comprehension, process skill, dan encoding. Penyebab utama kesalahan meliputi ketidakmampuan siswa dalam membuat model matematika, kurangnya pemahaman terhadap langkah-langkah penyelesaian, serta ketidakmampuan dalam menguasai materi prasyarat.]]>
