The purpose of this research was to develope computer-based multimedia learning with more contextual materials in teaching geometry for Middle School. This research was a developmental research. The research design in this study was Borg and Gall's design, which consits of: (1) Research and information collecting, (2) Planning, (3) Develop preliminary form of the product, (4) Preliminary field testing, (5) Main product revision, (6) Main field testing, (7) Operational product revision, (8) Operational field testing, (9) Final product revision, and (10) Dissemination and implementation. The products produced in this development research were Multimedia Learning that were packaged in CD form, consisting of; (a) the main menu, (b) Instructions for use, (c) learning material which was divided into two, they were sflat building material and building material. The response of the test subjects was obtained as follows: (1) the easeness of operating a multimedia CD based on usage instructions, stated as good = 16.67% and very good = 83,33%. (2) Display of images, animation, and color in multimedia, expressed as good = 8,33% and very good = 91,67%. (3) Systematics and clarity of material description, expressed as good = 16,67% and very good = 83,33%. After the results of the development in Multimedia Learning were packaged in CD form, this multimedia could be directly used by the teacher using computer. As for the total score analysis of the three aspects above the average score = 4.65 was categorized as very well. Thus, this research concluded that geometry products in multimedia learning were very easy to operate, systematic and needed by teachers and students
