Effectiveness of Guided Discovery-Based Worksheets to Improve Learning Outcomes in Acid-Base Concept Ma'firah, Marla Zainul, Rahadian This research was conducted to develop students’ worksheets based on guided discovery learning on acid-base materials. This student worksheet will be the basic content for developing a content learning system to improve the learning outcomes of 11th grade high school students in the pandemic era. Research and Development (R&D) using the ADDIE model is the research method used. Based on the research that has been carried out, the validity as measured by the Aiken's V formula is 0.85 which indicates that the developed students’ worksheets are valid. The value of practicality of teachers and students was obtained by 84% and 88% which indicated the very practical category. Then, the N-Gain value obtained is 54.68% which indicates that worksheet is effective in improving student learning outcomes. So it can be concluded that this student worksheet is valid, practical, and effective to be used as a basic content in developing a content learning system based on guided discovery learning on acid and base. Keywords: students’ worksheets, guided discovery, acid-base.  DOI: http://dx.doi.org/10.23960/jpmipa/v23i4.pp1347-1357 FKIP Universitas Lampung 2022-11-07 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article application/pdf https://jpmipa.fkip.unila.ac.id/index.php/jpmipa/article/view/542 Jurnal Pendidikan MIPA; Vol 23, No 4 (2022): Jurnal Pendidikan MIPA; 1347-1357 2685-5488 1411-2531 eng https://jpmipa.fkip.unila.ac.id/index.php/jpmipa/article/view/542/434 Copyright (c) 2022 Marla Ma'firah, Rahadian Zainul https://creativecommons.org/licenses/by-sa/4.0
