Abstract

Materi sintesis protein menjadi salah satu materi yang sulit dikuasai oleh siswa. Untuk menghadapi masalah tersebut, harus dilakukan inovasi terhadap metode pembelajaran agar siswa dapat lebih mudah belajar dan paham terhadap materi. Tujuan dari penelitian ini adalah untuk mendapatkan rancangan inovasi metode diksusi dan bermain peran berbantuan teknologi. Dalam penelitian ini, metode literature review dilakukan untuk mencari sumber terkait yang relevan dengan topik penelitian. Hasilnya adalah metode diskusi dapat diinovasi dengan berbantuan aplikasi Stormboard dalam pelaksanaannya, sedangkan metode bermain peran diinovasi dengan berbantuan Cell-Map Based Tag Magnetic. Dengan inovasi tersebut diharapkan akan membantu siswa dalam belajar sehingga siswa bisa mendapatkan hasil belajar yang lebih baik.

Abstract

This study aimed to develop and validate a three-tier multiple-choice diagnostic assessment instrument to identify misconceptions related to osmoregulation and the excretion system among Indonesian high school students. A total of 281 students from West Sumatra and Jambi Province participated in the research. Employing a quantitative approach, the psychometric properties of a 20-item test were analyzed using Rasch modeling. The analysis revealed that the instrument had strong item reliability (0.84), though person reliability was relatively low (0.55), indicating variability in students’ response consistency. Despite this, the test demonstrated high internal consistency, as shown by a Cronbach's Alpha of 0.90. The mean student ability level (-2.37) was significantly lower than the item difficulty level (0.00), suggesting widespread conceptual gaps among participants. All items met the model’s expectations, with average Outfit Mean Square (MNSQ) at 1.02 and Z-Standard at 0.1. The findings highlight the diagnostic tool’s effectiveness in detecting prevalent misconceptions in biology education. This study contributes to the field by offering a structured and psychometrically sound instrument, supporting more targeted instructional strategies to enhance conceptual understanding in science education.
