DEVELOPMENT OF STUDENT WORKSHEETS TO IMPROVE HIGHER ORDER THINKING SKILLS ON ACID-BASE SUBJECT
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.
