Problem Based Learning (PBL) as a learning device integrated with Computer Assisted Instruction (CAI) to enhance junior high school students comprehension on the concept of sound

Abstract

This research is a research development using 3D models that have been modified from 4D models by Thiagarajan. The aim of this research and development is to describe the developed learning device model that is the Problem Based Learning model integrated with Computer Assisted Instruction to enhance Junior High School students comprehension on the concept of sound. The data are gathered through the interview, filling out the questionnaire about validation of the learning device, physic test on the comprehension of the student, observation on the study process and students responses questionnaire. The test result shows that PBL learning device model integrated with CAI is feasible to be used in the learning process to enhance the students concept comprehension. The finding is based on the fulfillment of the four eligibility criteria such as; (1) Expert validation result and physic teacher for the developing learning device is highly feasible for the learning process; (2) The average percentage on the learning implementation in the test activity is decent; (3) There is an improvement on the concepts comprehension that is showed by the improvement of the average on the comprehension tests result; (4) The students responses are favorable in learning using the learning device PBL model integrated with CAI.
