Realistic Mathematics focus on contruct mathematics from concrete objects and environment objects.Student manipulate concrete objects and environment objects to help them in process concrete mathematics to abstrac mathematics.So student can cronstruct and make mathematics based on their way. According to Hans Freudental in Sugiman (2007), mathematics is a human activities and must be linked tu reality.Thus when student do activities to learn mathematics so in itself there is matematics process.Viewed from the side of teachers, review and analysis of learning mathematics that have been recorded in a Video Tape Recorder (VTR) is one way that can be done by the teacher to get the idea about concrete objects who can be used as mathematics learning context to construct mathematics from social activity.Use of VTR with realistic approach to learning mathematics can give some benefits: 1. Teacher have the opportunity to test the concrete objects and environment objects can be used a mathematics learning context to construct mathematics connections through social interaction. 2. Teachers have the opportunity to explore and reflect on the concepts realistic mathematics learning. 3. Teachers have the opportunity to exchange experiences with the other teachers about the development of realistic mathematics learning. 4. Teachers have the opportunity to reflect on the preparation process of teaching-learning mathematics in Junior High School according to the principle of PMRI.5.Teachers have the opportunity to reflect on the development of sources learning for teaching and learning mathematics in Junior high School according to the principle of PMRI. 6. Teachers have the opportunity to reflect on the development assesment activities for teaching and learning mathematics in Junior high School according to the principle of PMRI.
