Validity and Practicality of Student Worksheet on Project-Based Learning Based Renewable Energy Material for Phase E

Abstract

The application of the independent curriculum focuses on crucial material and the student development for character and competence.  The Student Worksheet used by teachers does not meet the requirements of the curriculum, i.e. it is project- according to, particularly in relation to renewable energy materials. This research aims to produce Student Worksheet on renewable energy materials according to for project according to learn for phase E that is valid and practical. The method used in this research is research and development (R&D). The model for development used is a 4-D model comprising 4 phases: define, design, develop and disseminate. Indicators were used to assess validity and practicality. In the validity analysis, three validators rated the presentation component as 0.87, visuals as 0.9, content feasibility as 0.83, and language feasibility as 0.9, all of which have excellent standards. Three physics teachers and 60 students did a practicality analysis, yielding an average score of 95% and 81.6%, suggesting that the criteria are extremely practical. According to the analysis of validity and usability, we can say that the Student Worksheet on renewable energy materials according to  project- according to learn is valid and practical, so that it can be used in renewable energy learn
