Designing Instructional Multimedia of Curved Three-Dimensional Shapes in Junior High Schools Through out Gorontalo Province

Development of instructional technologies gives rise to high demand, including math learning, that can be attained by the involvement of information and communication technology through instructional multimedia. Instructional multimedia are presentation media that combine the whole media elements, such as text, audio, video, animation, and graph. An appropriate and innovative design of instructional multimedia will indubitably provide an effective learning process to students, which then later positively contributing to their learning outcomes. The objective of this study was to develop character-based instructional multimedia of curved three-dimensional shapes in the ninth grade of junior high schools throughout Gorontalo province. The development model referred to the 4-D Model (Define, Design, Develop and Disseminate) proposed by Thiagarajan, Semmel and Semmel. It was shown that the developed interactive multimedia of curved three-dimensional shapes were valid and feasible according to experts, as well as being practical and bettering students’ responses during the lesson. Additionally, learning implementation by employing the multimedia arrived at excellent criteria and could improve students’ activities and learning outcomes. Based on the observation result, their activities reached excellent criteria. Student learning outcomes also gave classical mastery data with excellent criteria. All in all, instructional multimedia being developed were valid, practical, and effective to apply in the math learning process in the ninth grade of junior high school
