Abstract

Proses difusi dan osmosis merupakan konsep dasar dalam pelajaran IPA. Namun, beberapa siswa menemukan konsep-konsep ini menantang untuk dipahami, yang menyebabkan kesalahpahaman. Di Indonesia, penelitian tentang miskonsepsi terkait osmosis dan difusi masih jarang, kemungkinan besar karena hanya sedikit sekolah menengah pertama yang memasukkan topik ini ke dalam kurikulum mereka. Penelitian ini bertujuan untuk mengidentifikasi tingkat konsepsi siswa, miskonsepsi, dan penyebab miskonsepsi terkait difusi dan osmosis melalui tes pilihan ganda empat tingkat dan wawancara. Dalam penelitian ini, desain survei digunakan untuk mengumpulkan data. Sampel penelitian terdiri dari 55 siswa kelas 2 dan 64 siswa kelas 3 SMP. Hasil penelitian menunjukkan bahwa 62,1% siswa kurang pengetahuan, 24,1% memiliki pengetahuan ilmiah, 6,5% miskonsepsi, 4,4% false positive, dan 2,7% memiliki false negative. Meskipun tingkat miskonsepsi siswa tidak signifikan (<10%), masih terdapat miskonsepsi pada pemahaman siswa tentang difusi dan osmosis. Temuan penelitian ini menunjukkan bahwa miskonsepsi utama terkait pemahaman arah pergerakan molekul air dalam proses osmosis dan keliru mengklasifikasikan difusi sebagai transpor aktif. Berdasarkan wawancara, miskonsepsi dapat muncul karena pemahaman yang salah atau kurang lengkap, intuisi yang salah, dan pembelajaran yang tidak bermakna. Oleh karena itu, diperlukan upaya untuk mengatasi miskonsepsi dalam pembelajaran IPA khususnya tentang difusi dan osmosis. Penelitian lebih lanjut di berbagai jenjang sekolah dan dengan sampel yang berbeda diperlukan untuk mengatasi miskonsepsi dan meningkatkan pemahaman siswa. The processes of diffusion and osmosis are fundamental concept in science lesson. However, some students find these concepts challenging to grasp, leading to misconceptions. In Indonesia, research on misconceptions related to osmosis and diffusion is rare, most likely because of only a few junior high schools include these topics in their curriculum. This study aims to identify the level of students' conceptions, misconceptions, and the causes of misconceptions related to diffusion and osmosis through a four-tier multiple-choice test and interviews. In this study, a survey design was used to collect data. The research sample consisting of 55 students in secondary year 1 and 64 students in secondary year 3. The results showed that 62.1% of students demonstrated lack of knowledge, 24.1% had scientific knowledge, 6.5 % had misconceptions, 4.4% had false positives, and 2.7% had false negatives. Even though the level of students' misconceptions was not significant (<10%), there were still misconceptions in the students' understanding of diffusion and osmosis. The findings of this study indicate that the main misconceptions are related to understanding the direction of movement of water molecules in the osmosis process and mistakenly classifying diffusion as active transport. Based on the interview, misconceptions can arise due to wrong or incomplete understanding, wrong intuition, and not meaningful learning. Therefore, efforts are needed to overcome misconceptions in science learning, especially about diffusion and osmosis. Further research at various levels of school and with different sample is required to overcome misconception and improve students' understanding.
