Abstract

Guru harus mampu mempersiapkan dan melaksanakan kegiatan penilaian dengan benar, serta menggunakan hasil penilaian sesuai dengan keperluan. Tujuan penelitian ini adalah mengevaluasi kelayakan soal sumatif matematika pilihan ganda materi fungsi komposisi dan invers fungsi berbasis HOTS dan kontekstual. Penelitian ini menggunakan pendekatan deskriptif kuantitatif. Sebanyak 72 siswa kelas XI dari salah satu SMA Negeri di Kota Surabaya menjadi subjek penelitian ini pada semester ganjil tahun ajaran 2024/2025. Data dikumpulkan melalui tes pilihan ganda dengan 25 soal. Data dianalisis dengan software ANATES 4.0.9. Hasil penelitian terkait butir soal yaitu sebanyak 56% valid dan 44% tidak valid; reliabilitas tes mencapai 0,71, yang memiliki kategori tinggi; 16% soal memiliki daya pembeda sangat bagus, 48% bagus, 24% cukup bagus, dan 12% buruk; 68% soal memiliki tingkat kesukaran sedang, 20% mudah, dan 12% sangat mudah. Hasil penelitian menyatakan bahwa 40% memiliki kualitas soal yang sangat baik, sehingga layak digunakan pada tes sumatif yang akan datang atau dimasukkan ke dalam bank soal. Sementara 60% harus dievaluasi terlebih dahulu oleh peneliti. Ini akan membuat pengembangan bank soal lebih baik dan akan dapat digunakan untuk melakukan berbagai evaluasi pembelajaran.

Abstract

The problem addressed in this study is the persistence of teacher-centered learning and the limited innovation in developing digital teaching materials, which has resulted in students’ low comprehension of mathematical concepts. This study aimed to develop digital teaching materials in the form of Heyzine Flipbooks using the Problem-Based Learning (PBL) model on the topic of matrices to improve students’ conceptual understanding, while also meeting the criteria of feasibility and practicality. The research employed the ADDIE development model. Expert validators consisted of media experts, material experts, and design experts, while user trials involved mathematics teachers and Grade XI students at SMAN 8 Surabaya. Data were collected through expert validation sheets, as well as teacher and student response questionnaires. The results showed that media experts gave an average validation score of 3.98, material experts 3.98, and design experts 3.50, all categorized as very feasible. In addition, practicality scores were 3.96 from teacher responses and 3.86 from student responses, both categorized as very practical. These findings indicate that the developed teaching materials are feasible and practical to enhance students’ conceptual understanding of mathematics.
