THE DEVELOPMENT OF TEACHING MATERIALS INTERACTIVE MULTIMEDIA-BASED ON CHEMICAL BONDING FOR STUDENTS OF GRADE X AT SEKOLAH MENENGAH ATAS NEGERI 1 INDRALAYA UTARA

The purpose of the research are to produce teaching materials valid and practical multimedia-based and had effectivity towards students’ learning output on chemical bonding grade X. The methodology used in this research was development research by using Alessi and Trollip models whichcarried out in three phases, namely planning, design, and development. The validity was tested by alpha test, the practice of the teaching materials was tested by using betha test, whereas the effectivity of the learning output was tested by field test on the real class. The result of field test showed that the students’ learning output increase 44,37 with the average of the pretest score 32,19, meanwhile the result of the posttest was 76,56 with N-gain score 0,65 ( mid category). The conclusion of the research was that the teaching materials interactive multimedia-based that was developed was valid, practical and had effectivity towards students’ learning output. The suggestion for other researcher, it is that they are expected to develop quiz and games for metal bonding, random question for evaluation process, and closing evaluation program in order that the evaluation would not be able to be opened by the students before the time;(2) for the teacher, it is expected that the teaching material will be able to be applied as one of the teaching material in order the learning process would be easier; (3) for the school, it is expected that the teaching material interactive multimedia – based will be used as a learning resources in the teaching chemistry at X grade and as a model for other teacher.
