Abstract

Harapan dari kegiatan praktikum yang dilakukan di sekolah dapat membuat siswa mengkonstruksi pengetahuan dan keterampilan psikomotorik siswa. Faktanya dalam proses praktikum lembar kerja peserta didik (LKPD) yang digunakan masih memiliki standar yang belum memadai dan belum bisa memberikan pembelajaran bermakna kepada peserta didik. Sebagai contoh, LKPD transpor membran setelah dianalisis dengan menggunakan rubrik Diangram Vee Novak dan Gowin kualitasnya berada di kategori kurang. Sehingga perlu adanya rekonstruksi agar LKPD yang digunakan dapat membantu siswa dalam memperoleh pengetahuan. Penelitian ini menggunakan metode deksriptif kualitatif. Pemilihan sampel adalah purposive sampling yang menghasilkan satu LKPD transpor membran (difusi dan osmosis) pada kelas kelas XI fase F untuk dianalisis. LKPD dianalisis dengan rubrik diagram Vee Novak dan Gowin, kemudian dilakukan uji coba dan terakhir dilakukan rekosntruksi sebagai perbaikan dari kegiatan analisis dan ujicoba. LKPD yang telah direkonstruksi telah memuat lima komponen dari diagram vee yang dapat menjadikan praktikum bermakna dan dapat membuat siswa membangun pengetahuannya sendiri. Tahapan rekonstruksi LKPD transpor membrane diharapkan dapat mebantu siswa dalam memahami konsep difusi dan osmosis.

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.
