DEVELOPMENT OF STUDENT WORKSHEET BASED ON GUIDED INQUIRY MODEL ON ELECTROLYTE AND NON ELECTROLYTE SOLUTION MATTER TO TRAIN THE SCIENCE PROCESS SKILLS IN X GRADE SENIOR HIGH SCHOOL

This research aims to developt a guided inquiry based student worksheets that are feasible to train the science process skills in electrolyte and nonelectrolyte solution matter. This research used research and development Four-D Model which are consist of Define, Design, and Develop, and Disseminate stage. But in this research limited only in the develop stage. The data sources of this research are 12 students XI grade of senior high school, chemistry lecturer, and chemistry teacher. The feasibility data was analyzed by quantitative descriptive. The result of this research stated valid corresponded by the result of student worksheet 1 in the content criteria of 84.4%, the presentation criteria was 86,7%, the graphic criteria was 83,3%, the linguistic criteria was 88,9%, student worksheet 2 on content criteria 85.5%, presentation criteria 88.3%, 86.7% graphic criteria, linguistic criteria 88.9%. It was known that the student worksheets based on guided inquiry to be feasible to train the science process skill in the material of electrolyte and non electrolyte solution in class X grade and stated valid in terms of the validity of the content 84.44% and the validity of the constructs 86.7%, the student worksheet was stated practically in terms of response students with percentage 82,50%, also student worksheet declared effective from science process skills 91,67%.
