We know that Mathematics of Realistic emphasize to  construction of concret objects as starting points for student to get concept of mathematics. Concret objects and object of environmental can be used as context study of mathematics in developing relevant of mathematics through social interaction. Concret objects manipulatied by  student to support student in matemation process from concert form to abstract. Student require to give opportunity so that they can constructing and resulting mathematics by themselves Ianguage and ways. Therefore, needed activity of reflection to social activity so that earn happened confronting and reinforcement between discussion fundamental in structure of understanding of mathematics.

Effort of teacher to get ideas about concret objects and environmental objects able to be used to developing the context study of mathematics related to social interaction. Study and analysis about studying mathematics which have recorded into Video Tape of Recorder ( VTR) is one way  that able to be done by teacher.

By doing analysis and observation at VTR about study of mathematics where have been recorded by teacher which have executed study of mathematics with approach of realistic, hence other teacher can test and look for alternative development to obtaining of idea or concept about concret objects and environmental objects can be used as context study of mathematics  in developing relevant of mathematics through social interaction.

By using VTR study of mathematics with approach of realistic can give the following benefit such as, teacher get the opportunity to explore and reflect concepts study of mathematics of realistic, to change over experience with other teacher  about development of study of mathematics of realistic, to reflect preparation and development of process teaching learning mathematics in Junior High School as according to principles of PMRI, and to reflect development of activity asesment for process learn to teach mathematics in Junior High School as according to principles of PMRI.
