High schools description: Chemistry is a subject that is closely related to everyday life. However, chemistry learning, especially on the topic of reaction rates, often fails to connect the concepts taught with relevant real-world contexts. This situation makes it difficult for students to apply the concepts they have learned to solve problems. Therefore, there is a need for learning media that not only conveys the material but also encourages students to think critically and solve problems independently. The purpose of this study is to develop, test the feasibility, and determine student responses to a Problem-Based Learning (PBL) teaching module on the topic of reaction rates. The method used was R&D research with the ADDIE model, which includes Analyze, Design, Develop, Implement, and Evaluate. The results of the study indicate that the Problem-Based Learning (PBL) teaching module developed is valid and feasible for use, with a material validation score of 0.95 and a media validation score of 0.94. Student responses to the media showed an average percentage of 92%, which falls into the “Very Good” category. Based on the research results, the development of the Problem-Based Learning (PBL) teaching module is deemed valid and suitable as a learning medium. date: 2025 type: Thesis type: NonPeerReviewed format: text language: id identifier: https://eprints.untirta.ac.id/50707/1/Sinta%20Aida%20Febriani_2282210047_Fulltext.pdf format: text language: id identifier: https://eprints.untirta.ac.id/50707/2/Sinta%20Aida%20Febriani_2282210047_01.pdf format: text language: id identifier: https://eprints.untirta.ac.id/50707/3/Sinta%20Aida%20Febriani_2282210047_02.pdf format: text language: id identifier: https://eprints.untirta.ac.id/50707/4/Sinta%20Aida%20Febriani_2282210047_03.pdf format: text language: id identifier: https://eprints.untirta.ac.id/50707/5/Sinta%20Aida%20Febriani_2282210047_04.pdf format: text language: id identifier: https://eprints.untirta.ac.id/50707/6/Sinta%20Aida%20Febriani_2282210047_05.pdf format: text language: id identifier: https://eprints.untirta.ac.id/50707/7/Sinta%20Aida%20Febriani_2282210047_Reff.pdf format: text language: id identifier: https://eprints.untirta.ac.id/50707/8/Sinta%20Aida%20Febriani_2282210047_Lamp.pdf format: text language: id identifier: https://eprints.untirta.ac.id/50707/9/Sinta%20Aida%20Febriani_2282210047_CP.pdf identifier: FEBRIANI, SINTA AIDA (2025) PENGEMBANGAN MODUL AJAR BERBASIS PROBLEM BASED LEARNING PADA MATERI LAJU REAKSI UNTUK MENSTIMULUS KEMAMPUAN BERPIKIR KRITIS PESERTA DIDIK.
