Students' worksheet on circular cylinder topic using GeoGebra software through Discovery Learning model

Abstract

Students' worksheet is a sheet that contains material, descriptions, work steps, and exercises to help students comprehend and discover the concept of learning materials. But in fact, students' worksheets do not work well in schools yet. Students' worksheets only contain materials and exercises, not including the components of good students' worksheets. Therefore, it is necessary to develop students' worksheets which could help students to find their own concepts. This study aims to develop valid and practical students' worksheets based on discovery learning model employing GeoGebra in the topic of circular cylinder. This study was held at Year 9 on junior high school. The study is developmental research with ADDIE model, which consists of 5 steps: analysis, design, development, implementation, and evaluation. The research used validity and practicality instruments to assess students' worksheet. The validity instrument includes the assessment sheets for student worksheet and practical instrument includes student and teacher response questionnaires. The results showed that the students' worksheet fulfilled criteria (1) valid within the average score 4.5 of 5 for students' worksheets; and (2) practical with student response questionnaire average score of 88% and teacher response questionnaire average score 4.5 of 5.
