Abstract

Percentages are one of the important concepts in mathematics that are widely used in various contexts of daily life such as economics, commerce, and decision-making. However, various studies show that the concept of percentage is still a material that is quite difficult for students and prospective mathematics teachers to understand. These difficulties are generally related to the understanding of the basic concept of percentage, the use of the percent symbol (%), and the ability to relate the percentage value to the reference value in a problem. This study aims to analyze various percentage calculation strategies that can be carried out quickly and accurately based on the results of previous research. The method used in this study is a literature study by reviewing various scientific articles from SINTA-accredited national journals and international journals that are relevant to the topic of percentages in mathematics learning. Data is collected through documentation techniques by examining and analyzing research findings related to the percentage calculation strategy. The results of the study show that the use of mental calculation strategies, understanding the basic concept of percentages, and the use of visual models can help improve students' ability to calculate percentages more effectively and efficiently. Therefore, the right calculation strategy is essential to support the understanding of the concept of percentages in mathematics learning.

Abstract

Tujuan penelitian ini adalah untuk mengetahui pengaruh penggunaan model pembelajaran ekspositori terhadap pemahaman pembelajaran matematika siswa di SMP Negeri 12 Medan. Penelitian ini dilakukan pada hari Senin tangal 4 November 2024 yang berada di Jl. M.H Thamrin No.52, Pusat Ps., Kec. Medan Kota, Kota Medan . Penelitian ini menggunakan metode Kualitatif deskriptif dengan teknik pengumpulan data dengan wawancara. Hasilnya pengaruh model pembelajaran ekspositori yang menunjukkan bahwa meskipun strategi pembelajaran ekspositori berfokus pada penyampaian materi oleh guru dan memberikan kesempatan bertanya, tantangan utama tetap pada rendahnya kemampuan penalaran dan literasi matematika siswa, sehingga meskipun model ini kurang menarik dan menyebabkan kebosanan, penerapan pembelajaran kontekstual teridentifikasi sebagai metode yang lebih efektif dalam mengaitkan materi pelajaran dengan kehidupan nyata siswa.
