MODULE DEVELOPMENT WITH A GUIDED INQUIRY APPROACH IN COLLOID MATERIALS TO IMPROVE COGNITIVE LEARNING RESULTS AND SCIENCE PROCESS SKILLS OF HIGH SCHOOL STUDENTS
Colloid material is a chemical material at the high school level (SMA). Colloid material is composed of sub-submaterials including the colloid system, the properties of colloids, the manufacture of colloids, and the role of colloids in life. The colloid system sub-material explains the differences in solution, colloid, and suspension, types of colloids, the dispersed phase and the colloid dispersing medium. The sub-material on colloid properties describes the properties of colloids including the Tyndall effect, coagulation, adsorption, Brownian motion, colloid electrical properties, and protective colloids. The sub-material for making colloids describes how to make colloids by dispersion and condensation. Colloid preparation by dispersion can be divided into peptization dispersion, mechanical dispersion, and Bredig Arc, while colloid production by condensation can go through several reactions, namely reduction-oxidation reactions, double decomposition reactions and hydrolysis reactions.
Based on this description, it can be seen that colloid material is actually contextual, close to everyday life, such as in the colloid system submaterial which explains the types of colloids that are directly involved in student life, including hydrophilic colloids and hydrophobic colloids, examples of colloids. such as mayonnaise, milk, coconut milk gem stone, and so forth. In addition, colloid material also has many foreign terms that are not widely known by students such as condensation, adsorption, electrophoresis, peptization, and so on. Colloid material also has descriptive characteristics, there is no algorithmic material. This causes that in its application in schools, colloid material tends to be memorized by students (Rohma et al., 2013; Chittleborough, 2007), giving rise to several misconceptions, among which students assume that the solution is a mixture of a substance with water, the solution is always dilute, and colloids are always thick ( Trigunarti, 2008), colloids settle, colloids are solid, solutions are always in liquid form, and solutions are a mixture of matter and water (Purtadi & Sari, 2011).
- Produce a learning module with a guided inquiry approach on colloid material.
- Knowing the feasibility of the module being developed.
- Knowing the effectiveness of the developed modules in improving students' cognitive learning outcomes and science process skills.
- For student
Modules can be used as student learning materials independently. The module is expected to be able to help students improve their cognitive learning outcomes and science process skills.
- For Teachers
Modules with a guided inquiry approach can help teachers carry out learning on colloid material with a guided inquiry approach and help teachers to improve student cognitive learning outcomes and science process skills. Modules help teachers to train students to learn independently.
- For schools
Modules with a guided inquiry approach can be used as a learning support tool and a material reference for teachers in implementing learning in schools.
