Abstract

This study intends to analyze students' ability to determine the order of positive and negative integers and to identify the difficulties they experience in understanding the concept. The subject matter is important because many students still experience confusion in comparing and ordering integers, especially when negative numbers are involved. This type of research uses a qualitative-descriptive approach. This study was conducted in grade VI of a public junior high school 13, Jember, with 32 students selected based on the willingness of the school and teachers, but only 6 students who met the criteria were selected. The instruments used included a written test and in-depth interviews. The results showed that students' understanding of the ordering of positive and negative integers is relatively low. Students often face challenges in distinguishing and ordering positive and negative numbers, especially when dealing with number lines or mixed operations. The main factor contributing to students' challenges is a lack of understanding of the basic concepts of integers and their application on the number line. Students sometimes experience confusion regarding the order of numbers due to their incomplete understanding of numerical positions on the number line, as well as the principle of absolute value and the meaning of positive and negative signs. The results of this study are expected to provide a general overview of students' level of understanding and provide recommendations for effective learning strategies to improve their ability to correctly order integers.

Abstract

Children with autism spectrum disorder (ASD) often have difficulty understanding abstract concepts such as numbers, requiring interactive and concrete learning media. This study analyzed the systematic thinking, or algorithmic processes, of children with autism spectrum disorder as they solved complex Sudoku puzzles. Using a qualitative descriptive approach, three students with different levels of functioning at extraordinary school C TPA Jember were observed. This study used a 4x4 dot Sudoku game with pictures as a more easily understood learning medium. Data analysis was conducted by comparing data from the work results, visual documentation, and field notes. Data analysis used an interactive qualitative approach based on Miles and Huberman. The results indicated that picture Sudoku can support the algorithmic thinking of children with ASD, although the level of success varies based on individual abilities. Students with lower functional levels require full guidance, but students with higher functional levels lack sufficient independence and problem-solving skills. The conclusion of this study is that picture Sudoku has proven to be an effective tool for improving the algorithmic thinking of children with autism, highlighting the importance of concrete and adaptive learning media.

Abstract

Quality education in the SDGs aims to improve high-level thinking and problem-solving capabilities at all levels of education. Nevertheless at SMP Baitul Arqom, students has difficulties in solving mathematical problems, especially in social arithmetic. The aim of this research is to determine the ability of 8th grade students at SMP Baitul Arqom in solving social arithmetic problems in terms of impulsive and reflective cognitive styles. This research approach is descriptive, which describes the level of students' problem solving abilities based on impulsive and reflective cognitive styles. Then this research is a qualitative type, because the findings that will be explored in this research do not require procedural statistical analysis. This research was carried out at SMP Baitul Arqom Balung. Data sources include arithmetic test questions, MFFT, and interviews. The research subjects were class VIII students at SMP Baitul Arqom. Based on the results of the MFFT test and social arithmetic problem solving for 8th grade students at SMP Baitul Arqom, it shows that there were 9 impulsive students, 11 reflective students, and 4 students who were neither categorized as impulsive nor reflective. There is a clear difference between impulsive and reflective students. Impulsive students, IS1 and IS2, tended to be quick in responding but often inaccurate, indicating the need for practice in slowing down the decision-making process to increase accuracy. Meanwhile, reflective students, RS1 and RS2, were very accurate but slow, indicating the need for practice in speeding up the thinking process without sacrificing quality

Abstract

Penelitian ini bertujuan untuk mengeksplorasi implementasi pendekatan STEM pada materi fungsi kuadrat melalui proyek pembuatan ketapel dan pemanfaatan aplikasi GeoGebra guna meningkatkan pemahaman siswa SMK. Kombinasi pendekatan STEM dengan proyek ketapel dan GeoGebra dalam konteks pembelajaran fungsi kuadrat di SMK masih relatif jarang diteliti,, sehingga memberikan kontribusi kebaruan dari sisi metodologis dan kontekstual. Ketapel dipilih sebagai produk proyek karena memiliki lintasan parabola yang secara kontekstual merepresentasikan grafik fungsi kuadrat, sehingga memudahkan siswa dalam mengaitkan konsep matematika dengan fenomena nyata. Penelitian ini menggunakan pendekatan deskriptif kualitatif dengan teknik analisis data model Miles dan Huberman yang meliputi reduksi data, penyajian data, dan penarikan kesimpulan. Data diperoleh melalui observasi, wawancara, dokumentasi, dan tes pemahaman siswa. Hasil penelitian menunjukkan bahwa pendekatan STEM melalui proyek ketapel dan penggunaan GeoGebra mampu meningkatkan keterlibatan siswa dan memperdalam pemahaman konseptual serta representasional mereka terhadap fungsi kuadrat. Peningkatan ini tampak dari hasil tes pemahaman dan pernyataan siswa dalam wawancara, seperti pemahaman mereka terhadap bentuk grafik parabola dan parameter-parameter fungsi kuadrat. Simpulan dari penelitian ini mengindikasikan bahwa integrasi proyek kontekstual dan teknologi dapat menjadi strategi efektif dalam pembelajaran matematika di SMK
