Penelitian ini merupakan penelitian kuantitatif yang bertujuan untuk mendeskripsikan profil model mental siswa tentang larutan elektrolit dan nonelektrolit di SMA Negeri 8 Denpasar. Penelitian menggunakan teknik survey di kelas X IPA dengan melibatkan 155 orang siswa. Pengumpulan data dilakukan dengan pemberian tes model mental berbentuk pilihan ganda dua tingkat (two-tier test). Analisis data dilakukan dengan cara mengelompokan kemiripan jawaban siswa ke dalam tipe model mental tertentu. Hasil penelitian ini menunjukkan, bahwa profil model mental siswa kelas X IPA tentang larutan elektrolit dan nonelektrolit, sebanyak 12,85% tergolong model mental ilmiah dan 87,11% model mental alternatif, yang terdiri atas 63,85% benar sebagian, 19,63% miskonsepsi khusus, dan 3,63% tidak ada tanggapan. Dengan demikian, sebagian besar siswa belum memiliki model mental yang untuhuntuk memahami materi larutan elektrolit dan nonelektrolit.Referensi
