Abstract

This research aims to analyze students' difficulties related to mathematical dispositions and measure students' abilities in solving problems related to three-variable linear equation systems based on mathematical dispositions. Descriptive analysis methods are used in this qualitative research. All X-G students were given a mathematical disposition survey as part of the data collection process for this research. Three students were selected from each mathematical disposition category to take a test of their contextual problem-solving skills. Based on the results of the research, there were three groups of students in class X-G SMAN 1 TOROH, namely 3 students with high mathematics dispositions, 14 students with medium mathematics dispositions, and 16 students with low mathematics dispositions. Based on the analysis of answers and discussions, students with strong mathematical skills have excellent problem-solving skills because they meet three problem-solving indicators, namely making a problem-solving plan, implementing a problem-solving plan, and evaluating problems. Students have difficulty in the indicator of understanding problems because they are not used to writing what they know and what is asked. Students with a moderate mathematical disposition meet two indicators of problem-solving, namely creating and implementing a problem-solving plan, so they are in the moderate category in terms of problem-solving. Students with moderate mathematical dispositions also have difficulty writing the conclusion of the problem. Because students with low mathematical dispositions only fulfill one indicator, namely evaluating the problem, these students have problem-solving skills in the low category. In addition, students with low mathematical dispositions had difficulty in applying the formula.

Abstract

Matematika membutuhkan kreativitas dalam mengeksplorasi masalah supaya tidak mereplikasi karya orang lain. Semakin tinggi tingkat kreativitas siswa, maka semakin bagus kemampuan untuk menyelesaikan masalah. Salah satu model pembelajaran yang dapat meningkatkan prestasi belajar siswa adalah model pembelajaran Team Assisted Individualization (TAI). Kemampuan berkomunikasi matematika mempunyai korelasi yang signifikan dengan model pembelajaran TAI, karena siswa dilatih untuk saling menolong, berpendapat, berdiskusi, mempertajam pengetahuan, dan menghilangkan batasan-batasan antara siswa yang pandai dengan siswa yang kurang pandai (Tinungki : 2015). Dalam penelitiannya, Tinungki meneliti model pembelajaran TAI untuk meningkatkan kemampuan komunikasi matematika siswa dalam mata pelajaran probabilitas. Hernawati (2014) dalam penelitiannya menyatakan bahwa siswa yang dikenai model pembelajaran tipe TAI dengan lembar kerja bersetting Teori Belajar Bruner dapat meningkatkan prestasi belajar yang lebih tinggi daripada siswa yang dikenai model pembelajaran langsung. Nilai pelajaran siswa pada materi program linear yang diberikan model pembelajaran TAI lebih tinggi dibandingkan nilai siswa yang diberikan model pembelajaran langsung (Tilaar, 2014). Makalah ini akan membandingkan model pembelajaran Team Assisted Individualization ( TAI) dengan model pembelajaran Langsung pada mata pelajaran garis dan sudut, dengan sampel adalah siswa SMP di Kabupaten Sukoharjo kelas VII. Peneliti menggunakan 3 sekolah untuk penelitian,yaitu sekolah dengan kategori tinggi, sedang, dan rendah. Hasil penelitian menunjukkan bahwa pada siswa yang dikenai model pembelajaran Team Assisted Individualization ( TAI) mempunyai prestasi belajar matematika yang lebih baik daripada siswa yang dikenai model pembelajaran langsung. Siswa yang mempunyai kreativitas belajar tinggi mempunyai prestasi belajar matematika yang lebih baik daripada siswa yang mempunyai kreativitas belajar sedang maupun rendah, siswa yang mempunyai kreativitas belajar sedang mempunyai prestasi belajar matematika yang sama dengan siswa yang mempunyai kreativitas belajar rendah.

Abstract

Mathematics plays a crucial role in developing students' cognitive skills, particularly at the junior high school level. One type of question commonly used in assessments is the Higher Order Thinking Skills (HOTS) question, which requires students to think critically, creatively, and analytically. However, many students still struggle with solving HOTS questions, often due to insufficient understanding of basic concepts, difficulties in applying those concepts, and low levels of self-directed learning. This study aims to provide an overview of student errors in solving HOTS problems based on Newman Theory in terms of learning independence. The method used in this research is a descriptive qualitative approach that worked on HOTS questions. Data were collected through tests, interviews, and self-directed learning questionnaires. The findings indicate that students' errors are largely related to challenges in concept mastery (K1), problem-solving strategies (K2), and a lack of independence in learning. Moreover, students with higher levels of self-directed learning performed better in solving HOTS questions. Based on these findings, it is recommended that educators implement teaching strategies that enhance students' self-directed learning, such as problem-solving activities and regular HOTS practice, to reduce errors in solving questions that require higher-level cognitive skills.

Abstract

This study examines the effectiveness of Kahoot!, a game-based learning platform, in improving junior high school students’ conceptual understanding in mathematics. A quasi-experimental method was applied involving two eighth-grade classes at SMP Negeri 2 Teras: one as the experimental group using Kahoot and the other as the control group receiving conventional instruction. Data were gathered through pretests, posttests, questionnaires, and observations. The t-test analysis revealed a significant difference in student performance (t_count = 2,4132 > t_table = 2.0086 at α = 0.05), with the experimental group achieving a moderate N-Gain of 0.56. These findings demonstrate that Kahoot fosters student engagement, encourages real-time feedback, and supports varied learning styles, contributing to enhanced conceptual understanding. The integration of Kahoot in mathematics instruction, particularly on abstract topics like statistics, is shown to create a more interactive and student-centered learning environment. Educators are encouraged to incorporate technology-enhanced tools such as Kahoot to support active and meaningful learning processes.
