Practicality of Physics E-books Based on Problem-Based Learning Oriented to Higher Order Thinking Skills for Students

Abstract

Human resources with high-level thinking abilities, such as critical thinking, creativity, communication, teamwork, independence, cross-cultural understanding, and ICT literacy, are needed for 21st-century growth. However, cultivating high-order thinking skills is still not optimal and does not meet the needs of the 21st century. In fact, learning in schools has not met expectations, as reflected in TIMSS and PISA. The result of this research is the development of a physics e-book based on problem-based learning oriented towards higher-order thinking skills for high school class X. This research aims to measure the practicality of the e-book. The method used in R&D uses the Plomp model. The results of practicality are seen based on the responses from physics teachers and students. The practicality instrument uses five criteria consisting of several indicators. The practicality of e-books based on teacher responses shows an average of 92% with a very high category. The practicality of e-books based on student responses shows an average of 81% with a very high category. The research results show that the developed e-book is practical and can be used during the physics learning process
