The Effectiveness of Guided Inquiry-Based Worksheets to Improve Students' Critical Thinking Skills on Archimedes’ Law Materials

Abstract

This study aimed to determine the effectiveness of Guided Inquiry-based Student Worksheets on Archimedes’ Law. This study used an experimental method with a research design of one group pretest-posttest design. The population in this study was all students of class XI MIA Public Senior High School 1 Sariwangi, the research sample was XI MIA 2. The sampling technique was done by using cluster random sampling. The data collection instrument used a pretest and posttest assessment sheet. Data analysis used statistical tests, namely N-Gain and t-test. The test result of the effectiveness of student worksheets based on guided inquiry using N-Gain analysis obtained a value of 0.97 with high criteria. Furthermore, the result of the t-test showed 15tcount>t(0,995)(30)">  that it was 4.15>2.75. This indicated that there was a significant difference between the pretest and posttest scores. Based on the average N-Gain and t-test, it can be concluded that guided inquiry-based student worksheets are very effective in improving students' critical thinking skills. The results of this study have the implication that guided inquiry-based student worksheets can be used in the implementation of learning as a form of assistance for students to improve students' critical thinking skills.
