Implementation and Evaluation of Using Virtual Laboratory Media to Learning Geometry in Universitas Terbuka and Universitas PGRI Semarang

The current condition of the virtual laboratory is developing so rapidly, one indicator is the number of Mathematics students both State and Private Universities in Central Java who are looking for references related to practical geometry courses via online between lectures, this raises concern as a lecturer in adding value to lectures, which are adapted to the 21st century learning era today by creating virtual laboratories based on Virtual Reality, research methods using the ADDIE R & D model (Analysis, Design, Develop, Implementation and Evaluation) after the product is finished, the next step is implementing and marketing the product in state university & private university in the region of Central Java and its surroundings, this is because the science faculty virtual lab product has not been developed much in Indonesia, another thing that makes the appeal of this virtual lab product is that it is able to display virtual and augmented reality which can increase motivation and learning outcomes. Student, based on the validation of media experts and material experts on the virtual geometry lab product, it scores 89,57 and 70,84 meaning that the virtual geometry lab product is very suitable for use, then more than 90% of lecturers and students at the Open University are very happy to use it
