Abstract

The purpose of this study was to determine the quality of daily test items in mathematics subjects on SPLDV material for class IX in the 2024/2025 school year. The research method applied in this research is quantitative descriptive method, with samples in the form of 16 student answer sheets and question sheets. Data were collected through interviews conducted with Mathematics subject teachers, to find out the purpose and technique of preparing questions using documentation techniques copies of description question sheets and student answer sheets. Analysis of validity, reliability, difficulty level, and distinguishing power was carried out to determine the quality of the items. The results showed that in the validity analysis, there were 3 questions that were declared valid and one invalid. The results of the reliability analysis, the question was low with a Cronbach's Alpha value of 0,492, indicating weak inter-item consistency. The results of the difficulty level analysis showed that three questions were classified as easy (index 0,71–1,00), and one question was classified as moderate. And the results of the differentiating power analysis, the four description items have good differentiating power.

Abstract

Penelitian ini bertujuan untuk menganalisis tingkat pemahaman mahasiswa Jurusan Matematika Universitas Negeri Medan terhadap penggunaan bahasa Indonesia baku. Metode yang digunakan dalam penelitian ini adalah deskriptif kuantitatif dengan melibatkan 25 mahasiswa sebagai sampel penelitian. Data dikumpulkan melalui kuesioner berbasis Google Form yang berisi 10 soal pilihan ganda. Hasil penelitian menunjukkan bahwa tingkat pemahaman mahasiswa terhadap bahasa baku bervariasi, dengan skor berkisar antara 20 hingga 100 poin. Faktor utama yang memengaruhi pemahaman mahasiswa meliputi latar belakang pendidikan, kebiasaan membaca dan menulis, lingkungan akademik, serta motivasi pribadi. Penelitian ini menyimpulkan bahwa sebagian besar mahasiswa memiliki pemahaman yang cukup baik terhadap bahasa baku, tetapi masih mengalami kesulitan dalam menerapkannya secara konsisten. Oleh karena itu, diperlukan strategi pembelajaran yang lebih efektif, seperti seminar kebahasaan dan latihan menulis akademik, untuk meningkatkan penguasaan bahasa baku di kalangan mahasiswa.
