Development of teaching materials like PISA for physics mechanical wave topic in high school

This study aims to describe the validity, practicality and effectiveness of physics teaching material like PISA. The method carried out in this study uses Research and Development (R&D) development research using the ADDIE model consisting of 5 main phases or stages, namely 1) Analyze (Analysis), 2) Design (Design), 3) Develop (Development), 4) Implement (Implementation), 5) Evaluate (Evaluation). Physics teaching materials developed in the form of teaching materials like PISA. The subjects in this study were students of class XI MIA I SMA Swasta Dharma Pancasila Medan. The results of the study obtained that the validity of teaching materials to the material by the validator obtained results from the content feasibility aspect of 88%, the language feasibility aspect by 86% and the presentation feasibility aspect by 87% while the validity of the teaching materials to the media by the validator obtained a result of 87% so that it met the category valid. The results of the effectiveness test show that teaching materials are effective for use in the learning process with a percentage value of 82% with a very effective category. The practicality of teaching materials in the very practical category of student responses obtained a percentage value of 90%. This shows that the physics teaching materials like PISA have met the valid, practical and effective criteria. And there is an increase in student learning outcomes in the good category after applying high school physics teaching materials like PISA.
