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. ------------------------------------------------------------------------ * Corresponding author. brought to you by CORE View metadata, citation and similar papers at core.ac.uk provided by GSSRR.ORG: International Journals: Publishing Research Papers in all Fields
