Abstract

Penelitian ini didasarkan pada pentingnya memastikan bahwa butir soal pilihan ganda yang digunakan dalam evaluasi pembelajaran matematika di kelas 12 memiliki kualitas yang baik. Kualitas tersebut mencakup validitas, yaitu kemampuan sebuah soal untuk menilai apa yang memang seharusnya diukur, serta reliabilitas, yaitu tingkat konsistensi hasil pengukuran. Penelitian ini bertujuan untuk menganalisis validitas dan reliabilitas butir soal pilihan ganda pada mata pelajaran matematika semester genap di SMAN 1 Adiankoting. Pendekatan yang diterapkan dalam penelitian ini adalah metode kuantitatif dengan menggunakan teknik analisis statistik. Validitas soal diukur menggunakan korelasi biserial, sedangkan reliabilitas soal diukur dengan rumus Alpha Cronbach. Dari 10 soal pilihan ganda dengan 15 orang subjek penelitian, hasil analisis menunjukkan bahwa sebanyak 9 butir soal memiliki validitas yang baik, namun terdapat 1 soal yang tidak memenuhi kriteria validitas dan perlu diperbaiki atau direvisi. Dari sisi reliabilitas, nilai Alpha Cronbach yang diperoleh menunjukkan bahwa soal-soal tersebut memiliki konsistensi yang cukup tinggi, sehingga dapat dipercaya sebagai instrumen evaluasi. Dari hasil penelitian ini, dapat disimpulkan bahwa secara keseluruhan butir soal telah memenuhi kriteria validitas dan reliabilitas, diperlukan perbaikan pada beberapa soal agar keseluruhan tes dapat lebih akurat dan konsisten dalam mengukur kompetensi siswa.

Abstract

Mathematics is often perceived as a difficult subject due to the large number of formulas that students must understand and memorize. This condition can lead to learning difficulties and trigger mathematics anxiety, which may reduce students’ ability to retain mathematical concepts. This study aims to examine various effective strategies for memorizing mathematical formulas based on previous research. The research employed a qualitative approach using a literature review method involving 30 relevant scientific articles obtained from several academic databases. Data were collected through a literature study, while the analysis was conducted by identifying, comparing, and synthesizing findings from the collected literature. The results show that strategies for memorizing mathematical formulas can be categorized into four main groups: audio-musical and artistic strategies, digital technology and gamification innovations, cognitive strategies through mnemonics and kinesthetic tools, and structured drill methods. These strategies have been shown to improve memory retention, learning motivation, and students’ learning outcomes. The findings indicate that the application of creative and multisensory learning strategies can help students memorize mathematical formulas more effectively.

Abstract

The Vedic numeral system from India is one of the ancient mathematical heritages with significant historical and scientific value. This study aims to examine the Vedic numeral system from historical and scientific perspectives through a critical literature review. The research method used is a literature study that gathers and analyzes various academic sources regarding the origins, development, and relevance of the Vedic numeral system in modern mathematics. The findings indicate that this system has made significant contributions to the development of the concept of zero and the decimal system, which form the foundation of modern mathematics. Additionally, the principles of Vedic Mathematics have been proven to simplify various arithmetic operations, making it an efficient method for teaching mathematics. Despite its advantages, the application of the Vedic numeral system in education still faces challenges, particularly in academic documentation and adaptation into modern curricula. Therefore, further research is needed to evaluate its effectiveness in learning and its application in various scientific and technological fields.
