Pengembangan Multimedia Interaktif Pada Pembelajaran Kimia Materi Struktur Atom Kelas X MIPA

DEVELOPMENT OF INTERACTIVE MULTIMEDIA IN LEARNING CHEMISTRY ATOMIC STRUCTURE MATERIALS FOR HIGH SCHOOL

Abstract

This research aims to gain the feasibility of interactive multimedia on the chemical learning of atomic structure materials class X Mipa. This research is a study using research methods research and developmen, the research design used is a 4D model that is limited to 3 stages, namely define, design and develop. This studies became performed at SMAN 21 Surabaya on 33 college students of class X Mipa. This observe used validation instrument sheets, pretest and posttest, student response questionnaires and student observation questionnaires. If the price of the validation end result is ≥61% then it’s taken into consideration valid, the practicality price is ≥61% then it’s taken into consideration sensible and the effectiveness price is ≥61% then it’s taken into consideration effective. The validity of the contents and constructs of 85.6% and 82.92% falls into the class of very valid. Practicality obtained by 96.71% and 95.83% of student observations is considered practical. Effectiveness is obtained from the learning results of students using pretest and posttest questions and obtained pretest results of 21.21% and posttest results of 100% so that there is a difference between pretest and posttest students' grades. This suggests that interactive multimedia atomic structure materials can be used as a medium of chemical learning.
