Development and Validation of students' Worksheet Based on Guided-Inquiry to Improve Students' Scientific Literacy Skills of Junior High School on Straight Motion Concept

Abstract

The student worksheet that is currently used generally contain material and questions. A student worksheet is only used on certain materials, so it has not been an effective teaching material. This research aims to develop guided inquiry-based worksheets to improve the ability of Scientific literacy in straight-motion material. The method used in this study is research and development. The research design used in this development refers to Lee and Owens with stages consisting of analyzing, design, development, implementation, evaluation. The worksheet developed has very high validity. This can be seen based on the average score on the material expert test of 0.90 with very high validity criteria and the design expert test obtained an average score of 0.90 with very high validity criteria. Based on the readability test obtained an average score of 0.85 with a very good category. The worksheets developed have been able to improve students' scientific literacy abilities. This can be seen from the n-gain test results of 0.8 with high criteria, and sig values. in the paired sample t-test of 0,000. Teachers and students also give a good response to the worksheet. The conclusions of this study are valid guided inquiry-based worksheets to improve students' literacy skills.
