Mathematics is a human activity (human activities) and must be linked to reality. Thus, when students do activities to learn math so in his place matematisasi process. There are two kinds matematisasi, namely: (1) matematisasi horizontal and (2) matematisasi vertical. Matematisasi horizontal proceeds from the real world into mathematical symbols. The process occurs in the student when he was confronted with the problems of life / real situations. While the vertical matematisasi is a process that occurs in the mathematical system itself; for example: the discovery of a matter menyelesaiakn strategy, linking relationships between mathematical concepts or applying the formula / formulas findings. 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. Through VTR bagainmana expected teachers to learn: 1) make the preparation process of teaching and learning (PBM) in junior high mathematics in accordance with the principles of PMRI; 2) develop learning resources for teaching and learning process (PBM) in junior high mathematics in accordance with the principles of PMRI;
3) develop assessment activities for teaching and learning process (PBM) in junior high school mathematics in accordance with the principles of PMRI, and 4) implement the learning process (PBM) in junior high school mathematics in accordance with the principles of PMRI. This is revealed by Masami Isoda related about the VTR is "VTR (Video Tape Recorder) for teacher education and reform movements in Mathematics Education, specifically for developing lesson study has some benefits as: a) short summary of the lesson with emphasis on the major problems in The lesson, b) components of the lesson and play events in the class, and, c) possible issues for discussion and reflection with teachers observing the lesson ". The use of VTR learning math with realistic approach can provide 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 learning math concepts realistic; 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 teaching and learning process (PBM) in junior high mathematics in accordance with the principles of PMRI; 5) Teachers have the opportunity to reflect on the development of learning resources for teaching and learning process (PBM) in junior high school mathematics in accordance with the principles of PMRI, and 6) Teachers have the opportunity to reflect the development of assessment activities for teaching and learning process (PBM) in junior high mathematics in accordance with the principles of PMRI.
