Abstract
ABSTRAK Penelitian ini bertujuan untuk memperoleh profil model mental siswa pada konsep pengaruh keadaan pereaksi dan katalis terhadap laju reaksi. Responden penelitian sebanyak tujuh siswa kelas XII dari salah satu SMA Negeri di Kota Bandung. Siswa dibagi menjadi tiga tingkat kemampuan, yaitu dua siswa dengan kemampuan tinggi, tiga siswa dengan kemampuan sedang dan dua siswa dengan kemampuan rendah. Metode deskriptif digunakan pada penelitian ini dengan instrumen Tes Diagnostik Model Mental Interview About Event (TDM-IAE). Berdasarkan hasil penelitian diperoleh dua tipe model mental yaitu Partial Understanding (PU) dan Partial Understanding with a Specific Misconception (PU/SM). Pada konsep pengaruh struktur dan luas permukaan terhadap laju reaksi terdapat 6 orang siswa (1, 2, 3, 4, 6, 7) memiliki profil model mental dengan tipe Partial Understanding (PU) dan 1 orang siswa (5) dengan tipe Partial Understanding with a Specific Misconception (PU/SM). Pada konsep pengaruh energi ionisasi terhadap laju reaksi terdapat 5 orang siswa (1, 2, 3, 4, 7) memiliki profil model mental dengan tipe Partial Understanding (PU) dan 2 orang siswa (5, 6) dengan tipe Partial Understanding with a Specific Misconception (PU/SM). Seluruh siswa memiliki profil model mental dengan tipe Partial Understanding with a Specific Misconception (PU/SM) pada konsep pengaruh katalis terhadap laju reaksi. Kata kunci : model mental, TDM-IAE, pengaruh struktur terhadap laju reaksi, pengaruh luas permukaan terhadap laju reaksi, pengaruh energi ionisasi terhadap laju reaksi, pengaruh katalis terhadap laju reaksi. ABSTRACT This research aims to obtain students’mental models profile on the concept of effect nature of reactants and catalyst on reaction rate. The respondents of this study were seven students of class XII from a high school in Bandung. The students were divided into three ability level, they are two students with high ability, three students with medium ability and two students with low ability. The research used a descriptive method with Tes Diagnostic Mental Model Interview About Event (TDM-IAE) instrument. From the data analysis, it was found that there were two types of mental model profiles, namely Partial Understanding (PU) and Partial Understanding with a Specific Misconception (PU/SM). In the concept of effect structure and surface area on reaction rate, 6 students (1, 2, 3, 4, 6, 7) have a mental model of Partial Understanding (PU) type and 1 student (5) of Partial Understanding with a Specific Misconception (PU/SM) type. In the concept of the effect ionization energy on reaction rate, 5 students (1, 2, 3, 4, 7) have a mental model profile of Partial Understanding (PU) type and 2 students (5, 6) of Partial Understanding with a Specific Misconception (PU/SM) type. Whereas, all students have a mental model profile with the type of Partial Understanding with a Specific Misconception (PU/SM) on the concept of the effect catalyst on reaction rate. Key words: mental model, TDM-IAE, effect of structure on reaction rate, effect of surface area on reaction rate, effect of ionization energy on reaction rate, effect of catalyst on reaction rate.
