Development of PJBL-Based Physics Edu Media to Improve The 21st Century Learning Skills of High School Students.

The purpose of this research was to create physics teaching resources that would enhance students ' 21stcentury skills in renewable energy. The R&D approach was used in conjunction with data collection methods including both test and non-test modes. This study involved three validators who assessed the learning materials from the perspectives of both material and media aspects. According to the assessment results, the material aspect received a rating of ' very good,' whereas the media aspect scored ' good.' The enhancement of 21stcentury learning competencies was gauged through pretest and posttest evaluation, revealing a rise in critical thinking, creativity, communication, collaboration, use of ICTs, as well as life and career skills. The study determined that the PjBL-Based Physics Edu learning materials could serve as a reliable instructional tool for teaching renewable energy topics with moderate effectiveness.
