Realistic Mathematics Education have two important point of view. They are mathematics must be close with children dan relevant to daily life and also mathematics is human activity. There are two mathematization, they are horizontal and vertical. Horizontal mathematization processed from real life situation to mathematics symbol. On the other hand, vertical mathematization is the process of reorganization within mathematical system itself, in example are search stategies to solve the proble, representing relation, using mathematics formula, etc.

Analyzation about mathematics learning that have record in Video Tape Recorder (VTR) is one of the method  to find ideas how to use real thing as a learning mathematics context. After learning trough VTR, teacher hoped be able to learn how to:

1.      Make mathematics lesson plan appropriate with realistic Mathematics education

2.      Develop references for teaching learning process in Junior high appropriate with princip of Realistic Maathematics Education

3.      Develop assesment for mathematics teaching learning proces for Junior High based on RME

4.      Implement mathematics teaching learning process in Junior High based on RME

Through observation and analyzation on VTR about mathematics learning, that have been recorded by teacher that have done mathematics teaching based on RME, so another teacher can find alternative development. Another teacher can find idea how to used concrete thing and environment object as context of mathematics teaching. A learning mathematics model that have been recorded have strength and weakness. So, teacher can discuss it to find new knowledge by compare it with their experiences. Weakness of VTR are not all aspect recorded, the quality of the pictures, and ay be moment shooting picture that not good.

Using VTR in mathematics learning give us benefit. They are:

1.     Teacher have opportunity to observe concrete thing and environment objects as teaching context

2.     Teacher have opportunity to reflect concept of RME

3.     Teacher have opportunity to excange experiences with another teacher about development of RME

4.     Teacher have opportunity to reflect references for mathematics teaching learning in Junior High based on principle of RME.
