The subjects of this study amounted to 22 students of class XI IPA 1 SMAN 1 Dawarblandong. The worksheets developed were very valid with the average results of content validity on students’ worksheets 1, 2, and 3 of 4.67; 4.56; 4.56, and construct validity on students’ worksheets 1, 2, and 3 of 4.63. The practicality of the student worksheet obtained a percentage of 93.2% in the very practical category. The student worksheet was assessed for effectiveness using the N-gain test and paired sample t-test on pretest-posttest results. The average N-gain was 0.63 with a medium category and sig (2-tailed) value of 0.000 <0.05. Based on these findings, it can be said that the guided inquiry-oriented student worksheets are valid, very practical, and effective in helping students improve their metacognitive skills.Keywords: students’ worksheet, guided inquiry, metacognitive skills, acid-base.DOI: http://dx.doi.org/10.23960/jpmipa/v24i1.pp310-323 FKIP Universitas Lampung 2025-05-02 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/290 Jurnal Pendidikan MIPA; Vol 24, No 1 (2023): Jurnal Pendidikan MIPA; 310-323 2685-5488 1411-2531 eng https://jpmipa.fkip.unila.ac.id/index.php/jpmipa/article/view/290/198 Copyright (c) 2025 Isti Indra Winarseh, Utiya Azizah https://creativecommons.org/licenses/by-sa/4.0
