The Practicality and Effectiveness of the PjBL Model-Based Electronic Student Worksheets Assisted Science Lab Kits to Improve Science Process Skills in Students

Abstract

This study aimed to determine the practicality and effectiveness of learning based on the student worksheet model based on a kit-assisted science laboratory project to improve science process skills in class. The type of research used in research and development using the Plomp model consists of a preliminary research stage, a development or prototype stage, and an assessment stage. The practical results consist of a teacher response questionnaire and a student response questionnaire with a value of 99.2% and 85.0% with a very practical category. The effectiveness of the knowledge competence of students with posttest results of 77.5%. The effectiveness of the student's science skill competence has increased compared to the previous meeting, with an average of 84.7% in the very good category. The electronic student worksheet based on the Project-Based Learning (PjBL) model assisted by the Science Lab Kits is practical and effective for improving science process skills in class
