Abstract

This research aims to the effectiveness of using audio-visual media based on problem-based learning to improve students' critical thinking ability on colloidal material course. The population of this research is XI MIPA students at SMAN 14 Bandar Lampung. The sample of this research is XI MIPA 6 as the experimental class and XI MIPA 4 as the control class. In this research, the method used is quasi experiment with the pretest-posttest control group design. The effectiveness of using problem based learning through audio visual media to improve students' critical thinking ability on colloidal materials is measured by the significant average of the n-Gain score between experiment and control class. The result shows that the n-Gain score of students’ critical thinking in the experimental class is 0.81 that is categorized “high”, and for the control class is 0.63 that is categorized “medium”. The effect size test results show that problem based learning through audio visual media has a "big" impact in improving students' critical thinking ability on colloidal materials. Based on these results, it can be concluded that problem based learning through audio visual media has a positive impact and effective in improving students' critical thinking ability on colloidal materials.Keywords: effectiveness, audio visual media, problem based learning, critical thinking, colloid.  DOI : 10.23960/jppk.v10.i3.2021.02

Abstract

The success of the learning process can be determined from the cognitive and affective aspects. One method involves learning activity of students to discover the concept itself is a method of guided inquiry (guided inquiry). One concept that requires the involvement of students in activities and make students more active is Colloidal Systems. The concept of colloidal systems require reasoning and explanations through reasoning. With such reasoning students can solve the problems and to apply them in everyday life. This study aimed to describe the effect of guided inquiry learning to mastery of concepts in the subject matter of the colloidal system. This type of research is experimental. The population in this study were all students of class XI Science SMAN 7 Bandar Lampung. Research sample class XI IPA 1 and XI IPA 2 selected using purposive sampling technique. The study design used was The Matching-Only Posttest-Only Control Group Design. Based on hypothesis testing, found that the average value of the colloidal system concept mastery class guided inquiry learning model applied is higher than the applicable class of conventional learning models. This shows that the application of the guided inquiry pembelajara affect colloidal systems concept mastery. Keywords: Effects, Guided Inquiry, Concept Mastery, Colloid Systems
