Pengembangan Modul Kesetimbangan Kimia Berbasis Inkuiri Terstruktur Dengan Menggunakan Tiga Level representasi Kimia Untuk Siswa kelas XI SMA

Abstract

Chemical equilibrium is one of the subject matter which is quite difficult for students to understand. This study aims to produce a structured inquiry-based chemical equilibrium module using three levels of chemical representation and to express the level of validity and practicality of the module developed. The type of this research is development research using a 4-D model. The stages in the 4-D model are define, design, develop, and dissaminate. The instruments used in this study are validity sheets, teacher response questionnaires and student response questionnaires given for module practicality tests given to 5 validators and 32 students of eleventh grade of Public Senior High School (SMAN) 1 Pariaman. From the results of data analysis using the Cohen kappa formula, it is known that the validity and practicality of modules developed is within a validity average of 0.82, a very high category, the teacher's practicality level is 0.89, a very high practicality category, and a practicality level for students is 0.82, a very high practicality category. Thus, a structured inquiry-based chemical equilibrium module using three levels of chemical representation (macroscopic, microscopic and symbolic) developed can help teachers and students in the learning process.
