Validity of guided inquiry-based student worksheets in mechanical waves and thermodynamics

Abstract

21st century learning, especially in learning physics leads to the achievement of Higher Order Thinking Skills (HOTS). These skills can be achieved with various efforts, both the application of learning models and the use of appropriate learning materials. This study aims to develop a valid guided inquiry-based students worksheet as one alternative that can be done to achieve HOTS. The use of this student worksheet can help improve students’ thinking skills through orientation activities, formulating problems, formulating hypotheses, collecting data, testing hypotheses, and formulating conclusions. This research used the ADDIE model. The validation of this student worksheet is in the fourth stage, namely the development stage, which is carried out after the product is created. The results of the validation analysis by experts showed that the guided inquiry-based student worksheets developed were in the very valid category with an average score of 83.1%. This shows that this worksheet has feasibility in terms of presentation, content feasibility, linguistic, and graphic aspects. The results of this validation can contribute as a basis for developing learning materials, especially supporting the optimization of HOTS.
