High schools description: Chemistry learning now not only emphasizes theoretical concepts, but also links chemistry with real life to develop critical thinking skills, as well as foster social awareness and environmental responsibility in students. One approach that can be used to achieve these goals is to integrate socio scientific issues into learning. The socio-scientific issues approach is closely related to improving critical thinking skills, because it encourages students to analyze, evaluate, and make decisions based on scientific evidence in the context of social problems. In addition, one of the Independent Curriculum materials in Phase E, namely Green Chemistry material, still causes many errors in students, so teaching materials are needed that can support the achievement of these learning objectives. This study aims to produce Student Worksheets Based on Socio Scientific Issues in Green Chemistry Material in Stimulating Students' Critical Thinking Skills. This type of research is development research, with the ADDIE model (Analyze, Design, Develop, Implement, and Evaluate). Data collection techniques use teacher and student needs questionnaire sheets, expert validation sheets, and student response questionnaire sheets. The results of the study indicate that this Student Worksheet meets the valid criteria with a validity score of 0.90. The results of the student response questionnaire obtained a percentage of 86% with the category of "Very Good". Thus, it can be concluded that the Student Worksheet that has been developed is valid and suitable for use in learning. date: 2025 type: Thesis type: NonPeerReviewed format: text language: id identifier: https://eprints.untirta.ac.id/48484/1/VITNA%20PUTRI%20RAMADANTI_2282210042_FULLTEXT.pdf format: text language: id identifier: https://eprints.untirta.ac.id/48484/3/VITNA%20PUTRI%20RAMADANTI_2282210042_01.pdf format: text language: id identifier: https://eprints.untirta.ac.id/48484/4/VITNA%20PUTRI%20RAMADANTI_2282210042_02.pdf format: text language: id identifier: https://eprints.untirta.ac.id/48484/5/VITNA%20PUTRI%20RAMADANTI_2282210042_03.pdf format: text language: id identifier: https://eprints.untirta.ac.id/48484/6/VITNA%20PUTRI%20RAMADANTI_2282210042_04.pdf format: text language: id identifier: https://eprints.untirta.ac.id/48484/7/VITNA%20PUTRI%20RAMADANTI_2282210042_05.pdf format: text language: id identifier: https://eprints.untirta.ac.id/48484/8/VITNA%20PUTRI%20RAMADANTI_2282210042_Ref.pdf format: text language: id identifier: https://eprints.untirta.ac.id/48484/9/VITNA%20PUTRI%20RAMADANTI_2282210042_Lamp.pdf format: text language: id identifier: https://eprints.untirta.ac.id/48484/10/VITNA%20PUTRI%20RAMADANTI_2282210042_CP.pdf identifier: RAMADANTI, VITNA PUTRI (2025) PENGEMBANGAN LEMBAR KERJA PESERTA DIDIK BERBASIS SOCIO SCIENTIFIC ISSUES PADA MATERI KIMIA HIJAU DALAM MENSTIMULUS KEMAMPUAN BERPIKIR KRITIS PESERTA DIDIK.
