Abstract
Nora Deselia Saragih. (8186182002). Development of Science Student Worksheets Based on Science Process Skills to Improve Students^ Critical Thinking Skills on Single and Mixed Substances Class V SDN 158468 Lumut 5. Graduate Program, State University of Medan. 2022.
This research is based on the use of Student Worksheets and the learning process that has not developed science process skills. This study aims to determine the feasibility of Science Process Skills-based Science Student Worksheets to improve students^ critical thinking skills in science learning and also to determine the effectiveness of using Science Process Skills-Based Science Student Worksheets to improve students^ critical thinking skills which were developed according to the assessment of experts, teachers. homeroom teachers, and students. The reason for doing this research is because science learning outcomes are still low and science learning tends to only use printed teaching materials. This research is a development research through 4D model by Thiagarajan. The results showed that: (1) based on material expert validation with an average score of 3.66 and media expert validation with an average score of 3.66, the Student Worksheet developed was included in the very good criteria and was declared very valid and worth using. (2) Science Student Worksheets based on Science Process Skills are said to be effective in learning with the assumption that students^ science scores are higher when using Science Student Worksheets. Meanwhile, students^ critical thinking skills increased by a percentage of 76% in the first test and 88% in the second trial. (3) Based on the data on students^ critical thinking mastery before using the Science Student Worksheet, an average score of 60 was obtained, while after using the Student^s Worksheet, the students^ critical thinking mastery data obtained an average of 75 with a gain score of 0.49 which was in the medium category. Based on these data, Science Student Worksh
