THE APPLICATION OF THE PROBLEM-BASED LEARNING MODEL TO IMPROVE THE STUDENTS CRITICAL THINKING SKILLS AND LEARNING OUTCOMES

Abstract

This study aims to improve the critical thinking skills and learning outcomes of Grade X students of Network Computer Engineering (NCE) of vocational high schools (VHSs) in the learning of PC repair and re-setting through the application of the Problem-Based Learning (PBL) model. This was a classroom action research. The study involve Grade X students of the NCE expertise competency as the research subjects. The data were collected through observation with a checklist instrument and a performance test. They were descriptively analyzed. The results of the study show that: (a) the application of the PBL model is capable of improving the students’ critical thinking skills in the learning of PC repair and re-setting at 24.2%,(b) the students’ critical thinking skills in the learning of PC repair and re-setting after the application of the PBL model is categories of critical thinking skills is very high as 20 students (69%), high categories as 7 students (24.2%), low categories as 2 student (6.9%) and very low categories as 0 student (0%), (c) the application of PBL model is capable of improving the the students’ learning outcomes in the learning of PC repair and re-setting at 31.03%, and (d) the students’ learning outcomes after the application of the PBL model namely the number of students who reach the KKM as much as 29 students (100%).
