Mathematics is a science that requires a lot of logic because a lot of abstract things. Every problem in our life can be related to the mathematical sciences. Thus, the application of mathematics in the our life is very important. A teacher who teaches mathematics at the school should related to subject matter with daily life so that students are easy to understand. One way is with a realistic mathematical learning. Realistic Mathematics Education emphasizes the construction of the context of concrete objects as a starting point for students to acquire mathematical concepts. Concrete objects and environment objects can be used as a context for learning mathematics in building mathematical connections through social interaction.
In the side of teachers, how teachers' efforts to obtain ideide about concrete objects and objects surrounding environment that can used as a context for learning mathematics in making onnections mathematics through social interaction? Assessment and analysis of learning mathematics that have been recorded into the video tape recorder (VTR) is one one way or businesses that can be done by the teacher.
One method of learning in realistic mathematics education is to use a video tape recorder (VTP). A mathematical model of learning that has been recorded in the VTR certainly has its advantages and disadvantages. So the teachers can discussion to acquire new knowledge in a way compare with the experience. As for the VTR itself also have drawbacks, such as: the limited point of view, not all aspects can be recorded, image quality, the moment of decision image that is not appropriate.
Using of VTR realistic approach to learning mathematics can be gives the following benefits:
1. Teachers have the opportunity to test the concrete objects and obyekobyek
environment can be used as a learning context mathematics in building mathematical 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 other teachers about the development of realistic mathematical learning.
4. Teachers have the opportunity to reflect on the preparation of the learning process
teaching in junior high school mathematics in accordance with the principles or PMRI
5. Teachers have the opportunity to reflect on the development of sources
learning to the learning process in mathematics at junior high school in accordance with principles PMRI.
6. Teachers have the opportunity to reflect on development activities assessment for teaching and learning process (PBM) in mathematics at SMP in accordance with principles PMRI.
