Implementation of higher order thinking laboratory (HOTLAB) on magnetic field with real blended virtual laboratory to improve students critical thinking skills

The 21st century demands critical thinking skills, problem solving, and communication skills, so physics education students must be prepared to have these skills in the current industrial 4.0 era. These skills can be trained and developed through Higher Order Thinking Laboratory (HOT-LAB) activities. The purpose of this study was to analyze the effect of the HOT-LAB laboratory type on the improvement of critical thinking skills on the concept of magnetic fields. This research uses One Group Pretest-Posttest Design. The instrument uses questions of practical understanding and understanding of 10 questions. The results of data analysis showed that the average N-Gain score for the experimental class was 45.3 and the control class was 35.7. The use of HOTLAB in a real blended virtual laboratory has moderate effectiveness to improve Critical Thinking Skills on the subject of magnetic field.
