DEVELOPMENT OF STUDENT WORKSHEET BASED ON GUIDED INQUIRY MODEL WITH KIT INSTRUMENT ON REACTION RATE MATTER TO TRAIN THE SCIENCE PROCESS SKILLS IN XI GRADE SENIOR HIGH SCHOOL 1 CERME

Abstract

This research aims to produce the student worksheet that feasible to training the science process skills to student. Student worksheet which developed complemented by the KIT instrument as auxiliary media based on the phases of the guided inquiry learning model to train the student Sciences Process Skills (SPS). The type of this research is using 4-D model development research with 12 students of XI MIA 6 Senior High School 1 Cerme. The data obtained was analyzed descriptively. The results showed that the theoretical feasibility of student worksheet with each criterion obtained a percentage of 80.55-89.58% with very good/very decent category. Empirical feasibility of student worksheet developed based on response result and observation result of student activity. The result of students response showed that student worksheet got positive response because it got the percentage of 86.11-91.67% with very good/very decent category. Observation results of student activity at the first meeting is categorized good because it was obtained on the range of the percentage that is 72.22-94.44% and at the second meeting the range of the percentage that is 80.56-94.44%. The improvement of science process skills of students got from the pre-test and post-test score of science process skills of student, which is the students get the range score of 18.75-43.75 in the pre-test while the post-test gets in range score of 81.25-93.75. The improvement of SPS students after using the developed student worksheet has a 64.58 -97.92% completeness percentage with n-gain ranges from 0.50 to 0.91 with medium to high category.
