Abstract

The era of digitalization requires students to always be creative so as not to be out of date, one way is to improve problem-solving abilities. This research aims to improve students' problem-solving abilities by applying a problem-based learning model. The sample used was students of class X-1 as the experimental class and class X-2 as the control class selected using simple random sampling. This type of research is a quasi-experiment and the instrument of problem-solving ability used is in the form of an essay which consists of 8 questions. The results of the study concluded that the problem-solving ability in the experimental class using the problem-based learning model was better than conventional learning

Abstract

Industrial revolution-based learning media 4.0 is urgently needed when it is in accordance with technological developments. The purpose of this research is to see the effectiveness of learning media based on Augmented Reality in learning. The research subjects were computer science study program students in the General Physics course, the type of research used was Research and Development (R&D) by applying the 4D model. The data collection technique used in this study was an assessment instrument with a questionnaire. Data analysis techniques were carried out to obtain good quality products that meet the aspects of validity, practicality and effectiveness. Based on the results of the study, it was obtained that AR-based learning media on material with special lens rays was valid, practical and effective so that it was concluded that it was feasible to use in learning
