PENGARUH MODUL KESETIMBANGAN KIMIA BERBASIS INKUIRI TERSTRUKTUR DENGAN TIGA LEVEL REPRESENTASI TERHADAP MODEL MENTAL SISWA

Abstract

Abstrak Materi kesetimbangan kimia merupakan materi yang dianggap sulit oleh siswa. Modul berbasis inkuiri terstruktur yang dilengkapi dengan tiga level representasi merupakan salah satu upaya dalam meningkatkan pemahaman siswa. Penelitian ini bertujuan untuk menentukan pengaruh penggunaan modul ini terhadap model mental siswa. Desain menggunakan posttest-only control design yang dilakukan di dua sekolah. Pada desain ini setiap sekolah memiliki dua kelompok yaitu kelompok eksperimen dan kelompok kontrol. Hipotesis diuji dengan uji-t menggunakan program SPSS 16.0. Tes model mental siswa menggunakan instrumen tes diagnostik two-tier. Hasil uji hipotesis untuk masing-masing sekolah sebesar 0,011 di SMAN 3 Padang dan 0,008 di SMAN 13 Padang. Hal ini menunjukkan adanya pengaruh penggunaan modul terhadap model mental siswa.Keywords: Modul, kesetimbangan kimia, inkuiri terstruktur, tiga level representasi, model mental Abstract  Chemical equilibrium material is material that is considered difficult by students. A structured inquiry-based module equipped with three levels of representation is an effort to improve student understanding. This study aims to determine the effect of using modules on students' mental models. The design used in this study used a posttest-only control experiment conducted in two schools. In this design, each school has two groups, namely the experimental group and the control group. The hypothesis was tested by t-test using SPSS 16.0 program. The students' mental model tests used a two-tier diagnostic test instrument. The results of hypothesis testing for each school were 0.011 in SMAN 3 Padang and 0.008 in SMAN 13 Padang. This shows the effect of using modules on students' mental models.Keywords: Module, chemical equilibrium, structured inquiry, three levels representation, mental modelStudents find it difficult to understand the material of chemical equilibrium. One of the efforts to overcome these student difficulties is to use a structured inquiry-based module equipped with three levels of representation. This study aims to determine the effect of using the module on students' mental models. This study used a posttest-only control design conducted in two schools. In the design, each school had two groups, namely the experimental group and the control group. The two-tier diagnostic test instrument was used to test the mental models of 134 students. The hypothesis was tested by ttest using the SPSS 16.0 program. The results of the ttest for each school were 0.011 at SMAN 3 Padang and 0.008 at SMAN 13 Padang, with a 0.05 significance level. The results of the t-test showed that the use of the module affected students' mental models.
