Abstract

Abstrak: Penelitian ini bertujuan menganalisis validitas dan reliabilitas instrumen literasi matematika yang dikembangkan untuk mengukur kemampuan literasi matematika mahasiswa. Penelitian menggunakan pendekatan kuantitatif deskriptif dengan data simulasi yang terdiri atas respons 18 mahasiswa terhadap 10 butir soal literasi matematika. Analisis instrumen meliputi validitas isi menggunakan indeks Aiken's V, validitas butir menggunakan korelasi Corrected Item-Total Correlation, serta reliabilitas internal menggunakan koefisien Cronbach's Alpha. Hasil analisis menunjukkan bahwa seluruh butir instrumen memiliki nilai Aiken's V pada rentang 0,83–1,00 sehingga memenuhi kriteria validitas isi yang tinggi. Nilai korelasi setiap butir lebih besar dari 0,30 yang menunjukkan bahwa seluruh butir valid secara empiris. Selain itu, instrumen memperoleh nilai Cronbach's Alpha sebesar 0,892 yang mengindikasikan tingkat reliabilitas sangat tinggi. Berdasarkan hasil tersebut, instrumen literasi matematika dapat digunakan sebagai ilustrasi metodologis dalam analisis instrumen, namun masih memerlukan pengujian menggunakan data empiris pada sampel yang lebih luas. Kata kunci: literasi matematika, validitas instrumen, reliabilitas, Cronbach's Alpha, Aiken's V.   Abstract : This study aims to analyze the validity and reliability of a mathematical literacy instrument developed to measure university students' mathematical literacy skills. The study employed a descriptive quantitative approach using simulated data from 18 students who responded to 10 mathematical literacy items. Instrument evaluation included content validity using Aiken's V index, item validity using Corrected Item-Total Correlation, and internal consistency reliability using Cronbach's Alpha coefficient. The findings indicated that all items achieved Aiken's V values ranging from 0.83 to 1.00, demonstrating high content validity. Furthermore, all item-total correlation coefficients exceeded 0.30, confirming satisfactory empirical validity. The instrument also yielded a Cronbach's Alpha coefficient of 0.892, indicating excellent internal consistency reliability. These findings indicate that the instrument serves as a methodological illustration; however, further validation using empirical data from a larger sample is recommended. Keywords: mathematical literacy, instrument validity, reliability, Cronbach's Alpha, Aiken's V.

Abstract

This study aimed to develop a culturally contextualized mathematics assessment instrument for Grade XI students by integrating Borneo ethnomathematics into mathematics assessment practices. This study employed a research and development (R&D) method using a modified model proposed by Wilson, Oriondo, and Antonio, consisting of three stages, namely test design, pilot testing, and test assembly. The study involved Grade XI students at MA Raudhah Islamiyah, Mempawah Regency, who were selected using a non-probability sampling technique. Data were collected through test administration and analyzed using SPSS and ANATES to examine item validity, reliability, difficulty index, discrimination index, and distractor effectiveness. The results indicate that the developed instrument meets the criteria for a high-quality assessment tool. Most items demonstrated high validity, with only a few requiring minor revisions. The instrument showed good discrimination (0.67) and a moderate difficulty level (0.66), indicating its effectiveness in differentiating students' mathematical abilities. In addition, 49% of the distractors functioned effectively. These findings suggest that integrating local cultural contexts into assessment design can produce valid and reliable instruments while enhancing the relevance of mathematics assessment for students. Therefore, the developed instrument can serve as an alternative assessment tool that promotes both conceptual understanding and cultural awareness in mathematics learning.

Abstract

Penelitian dilakukan dengan tujuan untuk menganalisis kemampuan siswa dalam memecahkan permasalahan menggunakan bahan ajar sistem persamaan linear di SMK Bina Sabjanoba. Metode dalam penelitian ini Peneliti menggunakan jenis penelitian kualitatif dengan pendekatan deskriptif. Subjek dalam penelitian ini merupakan siswa kelas X yang berjumlah 28 siswa. Teknik pengumpulan data dalam penelitian yakni tes dan juga angket. Intrumen dalam penelitian ini yaitu lembar soal tes kemampuan pemecahan masalah berkaitan dengan soal sistem persamaan linear serta lembar angket. Hasil penelitian menunjukkan kemampuan siswa dalam memecahkan permasalahan sistem persamaan linear dengan menggunakan bahan ajar sistem persamaan linear pada tingkat tinggi termasuk ke dalam kategori sangat rendah. kemampuan siswa dalam memecahkan masalah termasuk dalam kategori rendah kebanyakan siswa kesulitan dalam menyelesaikan masalah pada persamaan linear tiga variabel, sehingga bahan ajar yang dibuat masih perlu diperbaharui sehingga mudah dipahami oleh setiap siswa dan membantu siswa dalam memecahkan permasalahan sistem persamaan linear.

Abstract

This study aims to determine the learning outcomes through snakes and ladders game on addition and subtraction of whole numbers. The research method used is quantitative descriptive method. The quantitative approach in this study was used to find out a clear picture of the phenomenon during the learning process, and the research sample was students of class VII C MTsN 01 Pontianak. 2022/2023. The subjects in this study were class VII C students totaling 30 students. The data collection techniques used were test methods, and documentation. The results of data analysis showed that the completeness of student learning outcomes taught using snakes and ladders game media had a significant effect because the average student learning outcomes only increased. Based on the results of the research that has been done, it can be concluded that: students' learning outcomes have met the KKM.
