Development of Guided Inquiry-Oriented Worksheets to Train Students Metacognitive Skills on Acid-Base Material

Abstract

Abstract Improving students' metacognitive skills is needed to improve the quality of education in Indonesia. The purpose of this study was to develop guided inquiry-oriented student worksheets to assist students in improving metacognitive skills on acid-base materials. The Borg and Gall model was used in this research method. The instruments used were the validation sheet, student response questionnaire, student activity observation sheet, metacognitive skills pretest-posttest questionnaire, and metacognitive inventory questionnaire. 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 percent 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 less than 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.
