The Application Design of Interactive Multimedia of IT-based Mathematics Learning on Strengtening Students' Characters

This research aims to develop interactive multimedia application of Coordinate System-based on the strengthening of Grade VIII Junior High students’ characters. The development model used in this study refers to the 4-D model proposed by Thiagarajan, Semmel and Semmel consisting of Define, Design, Develop, and Disseminate stages. Product development was tested on 20 students and field test was conducted in three junior high schools namely SMPN 3 Gorontalo, SMPN 1 Kabila Bone Bolango District and SMPN 11 Gorontalo City. The results of this study indicate that interactive multimedia Coordinate System that has been developed: (1) Categorized valid and feasible according to the expert; (2) Multimedia interactive coordinate system is easy to use and improves learners' response in learning. In addition, the implementation of learning by using multimedia coordinate system is in very good criteria, (3) Multimedia can improve the activity and learning outcomes of learners which based on observations obtained the percentage of student activities by 89.75% for limited and average trial class percentage for the field trial class of 94.87% with very good criteria. Students' learning outcomes provide classical completeness data for the limited trial class of 87.50% and field trial classes obtained by an average percentage of 89.33% with very good criteria, (4) Improving character based on the above, the interactive Multimedia coordinate system developed has been said to be valid, practical and effective so that it can be used in the process of Mathematics learning at grade VIII Junior High School.
