Pengembangan E-Modul Pembelajaran Fisika Berbasis Model Trait Treatment Interaction (TTI) Berbantuan Flip PDF Professional Terhadap Keterampilan Berpikir Kritis

During the learning provided by educators in the classroom without paying attention to individual differences. Even though each individual is different from one another, what educators provide is the same for all individuals and learning facilities, so that learning is not in accordance with the speed of learning between students with high and low abilities. The purpose of this research is to produce an e-Module for Learning Physics based on the Trait Treatment Interaction (TTI) model with Flip PDF Professional on Critical Thinking. This type of research is Research and Development (R&D) using the Plomp development model which consists of three stages: 1) preliminary stage, 2) phenotype development, 3) evaluation or assessment. The instruments used are validity questionnaires, practicality questionnaires, effectiveness questionnaires and critical thinking test questions. The results of the e-Module development are very valid with an average score of 86% of the results according to 86%, according to language 92%, and media 80%. The practicality of the product by 84,16% educators and 83.82% by students in the very practical category. The effectiveness of the product is very effective with an average score of 88.79% of the student effectiveness questionnaire and the test results obtained an average score of 81%. Therefore, the e-Module Learning Physics based on the Trait Treatment Interaction (TTI) Model with Flip PDF Professional on Critical Thinking Skills is very valid, practical and effective.
