Abstract

Abstract: The purpose of this study was to determine whether the Needham learning model had a positive effect on students' understanding of trigonometric concepts. The research methods used are experimental and the study design used is quasi-experimental involving only post-tests. The study population consisted exclusively of students in Class X of Madrasah Aliya Al-Mubarok for the 2021/2022 school year. The samples in this study were classes X IPA 1 and X IPA 2 drawn using a cluster random sampling technique. Correct t-test statistics were used for data analysis. Based on the results of data analysis obtained 3.617 and 1,678. Based on these results, obtained , it can be concluded that there is a positive effect of the application of the Needhaam learning model on students' understanding of concepts.

Abstract

Kurangnya kemampuan representasi matematis siswa SMP Negeri 12 Kotabumi pada materi statistika menjadi permasalahan dalam penelitian ini. Tujuan penelitian ini untuk mendeskripsikan kemampuan representasi matematis bentuk visual, simbolik dan verbal siswa kelas VIII SMP Negeri 12 Kotabumi pada materi statistika. Penelitian ini menggunakan metode deskriptif kualitatif dengan pendekatan studi kasus. Subjek berjumlah 6 siswa yang dipilih menggunakan teknik purposive sampling. Instrumen pada penelitian ini adalah peneliti, instrumen tes, dan pedoman wawancara. Uji keabsahan data menggunakan triangulasi teknik. Analisis data menggunakan 3 cara yaitu reduksi data, penyajiaan data, dan penarikan kesimpulan. Hasil penelitian menunjukkan (1) Kemampuan representasi matematis bentuk visual kelompok tinggi mampu memenuhi indikator visual dengan tepat dan benar. Sedangkan kelompok sedang dan rendah mampu memenuhi indikator visual, namun diagram yang dibuat masih belum tepat (2) Kemampuan representasi matematis bentuk simbolik kelompok tinggi dan sedang sudah mampu memenuhi indikator simbolik, namun siswa kurang teliti dalam menyelesaikan permasalahan. Sedangkan kelompok rendah belum memenuhi indikator simbolik yaitu siswa tidak menyelesaikan permasalahan yang diberikan. (3) Siswa dari kelompok tinggi mampu memenuhi indikator verbal. Siswa dari kelompok sedang dengan kode S1 memenuhi indikator verbal, namun siswa dengan kode S2 belum mampu memenuhi indikator verbal. Untuk kelompok rendah siswa belum mampu memenuhi indikator verbal.

Abstract

Conceptual difficulties and visual representation barriers are often major challenges in learning integers, especially related to understanding negative numbers and mathematical operations such as addition and subtraction. This study aims to identify the problems faced by students in learning integers, evaluate the effectiveness of various teaching methods, and propose innovative approaches to improve students' understanding. The methodology used is a systematic review based on Systematic Literature Review (SLR), by analyzing relevant research articles using PRISMA guidelines. This study examines various learning strategies, such as the use of realistic contexts, innovative visual models, manipulatives, and interactive technology. The results showed that a real-world context- based approach and the use of visual models can significantly improve students' understanding compared to conventional methods. Students who engaged in manipulative-based learning and class discussions also showed better mathematical thinking flexibility. These findings highlight the need for further exploration of the use of real contexts, more innovative visual models, and the application of gamification technology in integer learning. In conclusion, integer learning requires a more innovative approach by integrating realistic contexts, new visual models, and interactive technology. This not only increases student engagement but also supports the development of conceptual and procedural abilities more effectively.
