Abstract

Penelitian ini dilakukan untuk melihat kemampuan pemahaman konsep konsep pecahan siswa setelah menggunakan media puzzle, hal ini dilakukan karena berdasarkan kenyataan dilapangan ditemukan bahwa siswa kesulitan dalam pengoperasian penjumlahan dan pengurangan pada konsep pecahan. Siswa hanya bisa membedakan penyebut dan pembilang pada pecahan, tetapi ketika diminta untuk mengoperasikannya kedalam penjumlahan dan pengurangan siswa tidak paham, apalagi untuk pengoperasian perkalian dan pembagian pada pecahan. Sehingga dalam penelitian ini digunakan metode kualitatif deskriptif dan berdasarkan hasil penelitian setelah menggunakan media puzzel pecahan ditemukan bahwa siswa-siswa akhirnya bisa menyamakan Antara penyebut dan pembilang pada pecahan, siswa juga bisa menyelesaikan operasi penjumlahan pada pecahan.

Abstract

This research aims to find out whether there is an influence of students' reading ability and learning motivation on the ability to solve mathematical story problems. This study uses quantitative research with a descriptive approach. This research uses data collection techniques, namely test methods, questionnaire methods, and documentation. This research was carried out at GKE Sidas Junior High School with a population of 58 people in grade 7 and a sample of 30 respondents. The results of the study showed that there was an influence of reading ability and learning motivation on problem-solving skills in mathematics story problems of GKE Sidas Junior High School students. The hypothesis test is proven by the F test which shows a significance value of 0.002 less than 0.005 which means that reading ability and learning motivation have a stealth effect on students' problem-solving ability in story problems. Reading ability and learning motivation contributed 38.3% to students' problem-solving ability in story problems and 61.7% were influenced by other variables that were not studied in this study.

Abstract

This study aims to describe the role of teachers in enhancing the mathematics learning motivation of Grade VII C students at SMP Negeri 6 Sengah Temila on the topic of plane geometry. The study is based on the issue of low student motivation, classroom inactivity, and a lack of confidence in mathematics. Teachers are not merely content deliverers but also facilitators who create an engaging learning environment and encourage student participation. This is a qualitative and descriptive study. The research subjects consist of one mathematics teacher and six students selected purposively based on high, moderate, and low levels of learning motivation. Data collection techniques include observation, interviews, and questionnaires. The results of the study show that the teacher has carried out an essential role by creating a positive learning atmosphere, relating the material to real-life contexts, using varied and creative teaching methods, and providing reinforcement and appreciation to students. Although most students showed increased learning motivation, some still felt neglected or did not receive an appropriate learning approach. Therefore, more adaptive and personalized teaching strategies are needed to optimally motivate all students. This study is expected to contribute to helping teachers develop more effective instructional approaches to enhance student motivation in learning

Abstract

Studi literatur ini bertujuan untuk menganalisis tren penelitian dengan menggunakan analisis bibliometrik yang terkait dengan Kecerdasan Buatan (AI) dalam pengajaran matematika. Pentingnya AI dalam pengajaran matematika tidak sesuai dengan banyaknya penelitian tentang hal tersebut. Sehingga penelitian ini disusun dengan tujuan untuk mengidentifikasi penelitian berkaitan dengan integrasi AI dalam pengajaran matematika selama 10 tahun terakhir.  Kata kunci yang digunakan untuk mengumpulkan artikel adalah “artificial intelligence” dan “mathematics teaching” dan diperoleh 460 dokumen di database scopus. Penelitian ini dilakukan dengan membatasi jumlah dokumen tergantung pada tahun, bahasa, dan jenis artikel. Batas tahun pada tahun 2014 hingga 2024, bahasa dibatasi hanya bahasa Inggris, dan dokumen dibatasi hanya pada jenis artikel. Jumlah dokumen dalam dekade terakhir meningkat dari 6 dokumen menjadi 26 dokumen. Zhongda Sun, yang berkecimpung dalam kecerdasan komputer, adalah penulis yang paling banyak dikutip. Negara paling produktif adalah Tiongkok yang menyalip jumlah publikasi Australia pada tahun 2021. Kecerdasan buatan dalam pengajaran matematika populer dalam ilmu sosial dan ilmu komputer dengan topik yang paling populer adalah siswa, kecerdasan buatan, dan guru. This literature study aims to analyze research trends by using bibliometrics analysis that related to Artificial Intelligence (AI) in mathematics teaching. The impact of AI in mathematics teaching did not match to the number of mathematics teaching research. So, this bibliometric study conducted in order to identify AI integration in mathematics teaching in last decade. Article gathered by two keywords, which are “artificial intelligence” and “mathematics teaching”and found 460 documents in scopus database. This study conducted by limiting the number of documents depend on years, language, and article type. The years limit in 2014 to 2024, languages limit to english only, and the documents limit to article type only. The number of documents in the last decade is increasing from 6 documents into 26 documents. Zhongda Sun, that concern in computer intelligence, is the most cited author. The most productive country was China that overtake Australia’s number of publications in 2021. Artificial intelligence in mathematics teaching was popular in social science and computer science and the most popular topics are students, artificial intelligence, and teacher.

Abstract

Abstrak Kemampuan visualisasi merupakan aspek krusial dalam memahami materi dimensi tiga. Tujuan penelitian ini yaitu menggambarkan kemampuan visualisasi siswa sekolah menengah atas dalam pembelajaran materi dimensi tiga berdasarkan gaya belajar. Subjek penelitian kualitatif ini dipilih dengan metode purposive sampling. Teknik pengumpulan data menggunakan tes essay berdasarkan indikator ketrampilan visualisasi. Teknik analisis data meliputi pengumpulan data, kategorisasi data, penyajian data dan penarikan kesimpulan. Hasil penelitian menunjukkan kemampuan visualisasi siswa berbeda berdasarkan gaya belajar. Siswa dengan gaya belajar visual menunjukkan kemampuan visualisasi yang sangat baik yaitu menyelesaian masalah, pencarian pola, pengonsepan, pengimajinasian, dan memvisualkan. Siswa dengan gaya belajar auditori menyelesaikan masalah, pencarian pola, dan memvisualkan, namun belum optimal dalam pengimajinasian dan pengonsepan. Siswa dengan gaya belajar kinestetik menyelesaian masalah dan pencarian pola, sedangkan mengimajinasikan hanya tercapai sebagian, dan pengonsepan serta memvisualkan belum terpenuhi secara memadai. Temuan ini menunjukkan adanya hubungan erat antara gaya belajar dan pencapaian kemampuan visualisasi dalam memahami materi dimensi tiga. Abstract Visualization ability is a crucial aspect in understanding three-dimensional material. The purpose of this study is to describe the visualization ability of high school students in learning three-dimensional material based on learning styles. The subjects of this qualitative study were selected using the purposive sampling method. The data collection technique used an essay test based on visualization skill indicators. Data analysis techniques include data collection, data categorization, data presentation and drawing conclusions. The results of the study showed that students' visualization abilities differed based on learning styles. Students with a visual learning style showed very good visualization abilities, namely solving problems, finding patterns, conceptualizing, imagining, and visualizing. Students with an auditory learning style solved problems, finding patterns, and visualizing, but were not optimal in imagining and conceptualizing. Students with a kinesthetic learning style solved problems and searching for patterns, while imagining was only partially achieved, and conceptualizing and visualizing had not been adequately fulfilled. These findings indicate a close relationship between learning styles and the achievement of visualization abilities in understanding three-dimensional material.
