The development of higher order thinking virtual laboratory on photoelectric effect

Abstract

Higher order thinking skills (HOTS) are potentially developed through physics laboratory activities intentionally designed to develop these skills to the students. This study aims to develop higher order thinking virtual laboratory (HOT-VLab) model on photoelectric effect concept to improving critical thinking skills (CTS) and students' creative problem solving skills (CPSS). The research method used is research and development with ADDIE model. Validation of HOT-VLab model has been done through expert review by physics learning expert (N=3). HOT-VLab model is implemented to a number of pre-service physics teachers (N=35) at a university in Bengkulu, Indonesia. The CPS and CPSS tests were performed both before and after the HOT-VLab model implementation to determine the CPS and CPSS enhancement obtained by the students. The results of the test data analysis show that the CTS and CPSS scores of students increased with N-gain are 0.54 and 0.53. Both N-gain scores have moderate category. In addition, it was found that the pretest and posttest scores of both types of tests are significantly different. It can be concluded that HOT-VLab model can be used to improve students' HOTS.
