Perancangan dan Validasi Perangkat Pembelajaran Dinamik pada Perkuliahan Geometri Analitik
There is a slight difference between college mathematics and school mathematics. Commonly, learning materials in college mathematics is very abstract, such a geometry analytical course. Its needed multirepresentativeand explorative learning materials as tool to help student learn the abstract materials. This article present result from research and development that aims to develop a teaching materials for analytic geometry course, a dynamic worksheet, in the form of GeoGebra file format and its worksheet. The Research and development 4D model, that is consist four phase: define, design, develop and disseminate, was implemented in this study (Thiagarajan, et. al., 1974). In the first year was done three phases of the define, design and develop with the aim of producing prototype dynamic worksheet that have been validated by experts. The results of validation show that prototype of dynamic worksheet developed already meet the criteria valid. The next phase must be done to meet the practical and effective criterias.
