Swaditya Rizki, Nego Linuhung (2016) Design Research And Development 4d Model For Developing Mathematicsteaching Materials
Teachers should be able to develo p teaching materials especially mathematics teaching materials, due to the low availability of quality teaching materials that suit the demands of the curriculum, students' characteristics, as well as the environment in which students live. Currently, many college students and researchers of mathematics in preparing the thesis or research have chosen to develop teaching materials with Research and Development (R & D) model 4D developed by Thiagarajan, et al. (1974). However, in practice, there are errors in understanding the development model in modifying the 4D into 3D. In this study, presented the results of a qualitative descriptive analysis research and development model 4D in particular area s of mathematics. The results of this analysis are used for re ference and ideas so that the researchers who conducted the research and development. Based on this assessment obtained by reference Research and Development (R & D) 4D model. stages of research 4D model that is Define, Design, Develop, Disseminate. Phase Define this is the front - end analysis, concept analysis, task analysis, and Specifying instructional objectives. Stage Design is designing prototype learning device for obtaining a preliminary draft. Phase Develop that is (1) expert appraisal followed by r evision, (2) developmental testing. Phase Disseminate divided into three activities, that is validation testing, packaging, diffusion, and adoption.
