Abstract

Most students find mathematics difficult because of its abstract nature. Especially in areas of spatial shapes that cannot be completed manually. This can have an impact by increasing students' math anxiety and reducing student motivation. So media is needed that can visualize abstract problems in mathematics. Geogebra is a program that allows students to get intuitive feelings and imagine mathematical processes. The aim of this research is to see the effect of using Geogebra media on students' anxiety and motivation in learning mathematics at State Elementary School 040461. This research is a quasi-experiment. This research was carried out at SD Negeri 040461 Berastagi. The population of this research is all students at SD Negeri 040461 Berastagi for the 2022/2023 academic year. The research sample was carried out using a random sampling technique, namely drawing lots to get the experimental class and the control class. The sample used is class VA and VB students. The use of geogebra media is taught in the experimental class while the control class uses conventional methods. The mathematical material used is spatial figures. Data were collected using anxiety and motivation questionnaires as well as tests at the posttest. Descriptive and inferential statistical methods were used to analyze data using SPSS. Descriptive and inferential statistical methods were used to analyze data using SPSS. Descriptive statistics are used to see the average and standard deviation. Inferential analysis is used for Multivariate Covariance (MANCOVA). The results showed that there was a significant difference between anxiety and mathematics motivation, where the average score of the experimental group was greater than the control group. The use of geogebra learning can influence students  anxiety and motivation at SD Negeri 040461 in mathetics.

Abstract

Era digital telah membawa perubahan besar di berbagai aspek kehidupan, termasuk pendidikan. Kemajuan teknologi informasi dan komunikasi (TIK) telah mengubah cara kita mengakses pengetahuan, berkomunikasi, dan belajar. Pendidikan tidak lagi terbatas pada ruang kelas fisik, melainkan telah merambah ke ruang digital melalui platform e-learning, aplikasi pendidikan, dan media sosial. Meski teknologi membawa banyak manfaat, era digital juga menghadirkan berbagai tantangan yang harus diatasi untuk memastikan pendidikan tetap relevan, inklusif, dan efektif. Artikel ini akan membahas tantangan utama pendidikan di era digital dan bagaimana dunia pendidikan dapat meresponsnya secara efektif. Perubahan teknologi telah menciptakan transformasi signifikan dalam proses pembelajaran. Pembelajaran yang dulunya berbasis buku teks dan kuliah tatap muka kini telah berkembang menjadi pengalaman yang lebih interaktif dan mandiri melalui platform digital. E-learning, pembelajaran daring (online learning), dan sumber daya pendidikan berbasis teknologi telah memberi akses yang lebih luas terhadap informasi. Namun, perubahan ini juga menuntut adaptasi dari berbagai pihak, termasuk guru, siswa, serta institusi pendidikan. Era digital tidak hanya mengubah metode pembelajaran, tetapi juga mengubah keterampilan yang dibutuhkan di dunia kerja. Keterampilan seperti pemecahan masalah kompleks, pemikiran kritis, kolaborasi digital, serta literasi teknologi menjadi semakin penting. Sistem pendidikan harus bisa merespons perubahan ini dengan memperbarui kurikulum dan metode pengajaran. Tujuan pengabdian kepada masyarakat ini adalah mengedukasi mengenai siswa mengenai cara menghadapi tantangan di era digital di SD Negeri 173539 Hutagaol. Pengabdian masyarakat ini akan dipublikasikan pada jurnal pengabdian masyarakat.

Abstract

The purpose of this study was to determine whether the problem-based learning paradigm is useful in improving high-level thinking skills or high-level thinking skills of students of SD Negeri 173531 MEAT Mathematics in the 2024-2025 academic year. This study uses a quasi-experiment as its research methodology. The population of the study was all students of SD Negeri 173531 MEAT Mathematics in the 2024-2025 academic year. The data collection method used a control class and an experimental class. The data collection method in this study used a pretest and posttest. The data analysis method used was the t-test (Independent sample T-Test). In addition, to determine the increase, an n-gain test was carried out. The research findings show that (1) the Problem-Based Learning Model is useful for improving high-level thinking skills (HOTS) or high-level thinking; (2) indicators of knowledge transfer, critical thinking, and problem solving are in the high, medium, and medium categories, respectively

Abstract

Hasil observasi yang dilakukan di Kelas V SDN 040444 Kabanjahe menunjukkan bahwa proses pembelajaran matematika tidak meningkatkan kemampuan pemecahan masalah siswa dan sikap ilmiah mereka. Dengan data ini, diperlukan model pembelajaran yang dapat meningkatkan kemampuan pemecahan masalah. Penelitian ini dilakukan di Kelas V SDN 040444 Kabanjahe dan meneliti dampak pembelajaran berbasis masalah terhadap kemampuan pemecahan masalah siswa Kelas V. Design quasi-experimental untuk penelitian ini menggunakan desain kelompok kontrol yang tidak setara. Dalam penelitian ini, teknik purposive sampling digunakan untuk mengambil sampel siswa dari kelas V.A (kelas Kontrol) dan V.B (kelas Eksperimen). Metode observasi dan tes digunakan untuk mengumpulkan data. Hasil penelitian menunjukkan nilai rata-rata pretes untuk kelas eksperimen 47, dengan standar deviasi 20,79, dan untuk kelas kontrol, nilai rata-rata pretes untuk kelas ini adalah 30, dengan standar deviasi 10,21. Uji normalitas dan homogenitas telah menyimpulkan bahwa data nilai pretes dari kelas eksperimen dan kontrol berdistribusi normal dan homogen. Kemampuan awal kedua kelas adalah setara, menurut hasil statistik yang signifikan. Setelah itu, kelas eksperimen diperlakukan menggunakan model pembelajaran berbasis masalah, sedangkan kelas kontrol diajarkan dengan metode pembelajaran konvensional. Setelah kelas selesai, ujian dilakukan. Nilai eksperimen rata-rata 98, dengan standar deviasi 6,15, dan nilai kontrol rata-rata 58,33, dengan standar deviasi 20,35. Kemampuan pemecahan masalah kelas V SDN 040444 Kabanjahe Tahun Ajaran 2023/2024 terpengaruh secara signifikan oleh model pembelajaran berbasis masalah. Kesimpulan ini dapat dicapai melalui pengujian statistik dengan uji-t satu pihak.

Abstract

This study aims to analyze the types of errors made by students in the Mathematics Education Study Program, taking the Algebraic Structures course, based on Newman's Theory. The research method used was descriptive qualitative research. The subjects were 30 students who obtained test scores below 60. The data analysis technique used was an interactive technique consisting of three activity flows: data reduction, data presentation, and conclusion drawing/verification. The data presentation used bipartite graphs and, where is the set of students and the set of error types, according to Newman. The results showed that the most common type of problem transformation error was found in problem number 1 (10 students), while the most common type of problem understanding error (comprehension error) was found in problem number 2 (19 students). Therefore, several follow-up actions are needed to strengthen a deeper understanding of the definitions and properties of Algebraic Structures, namely groups and rings, and the use of non-routine and varied problems.
