Main Article Content
Abstract
This study aims to determine the feasibility and response of teachers and students to student worksheets to increase student HOTS using the PBL model. This study uses the R&D (Research and Development) research method, using the 4D model (Define, Design, Develop, Disseminate). Data collection techniques using a questionnaire in the form of a questionnaire. The assessment instruments used were material and media feasibility assessment sheets, teacher response questionnaires, student response questionnaires, and data analysis using a Likert scale. The feasibility of the Student Worksheet (LKPD) was assessed by 4 experts, namely two subject experts and two media experts. The feasibility of the subject obtained an average of 87.35% with the criteria of "Very Eligible" and the eligibility of the media obtained an average of 95.85% with the criteria of "Very Eligible". Furthermore, the results of teacher responses to Student Worksheets (LKPD) obtained an average of 95% with the criteria "Very Eligible" and student response results obtained an average of 91.78% with the criteria "Very Good". According to the results of the Student Worksheet (LKPD) research to improve higher-level thinking skills in acid-base material, it is stated that it is feasible to be tested in acid-base learning.
