peer teaching comment

I support with peer-teaching as one of the activities of in service mathematics. I rightfully proud with Mr. Marsigit, et.al, to initiative peer-teaching activities program in P4TK Yogyakarta. Much of mathemathics is concerned with the development of such concepts that so often gives mathematics a reputation of being very difficut. With peer-teaching activities in service mathematics training can be support to conceiving mathematics concepts.
According to me, the reflection in teaching learning proces is importance to know a shortage in proces. The learning of activity, the students di their worksheet in group to solve a problem. A teacher good responsive with his/her students problem in learning of mathematics in concepts. Forming an understanding of any abstract can be difficult. However, there is little in mathematics that is more difficult or abstract than concepts such as truth, courage, or honesty. In every instance there are three things involved in mastery and comunication of such concepts are example, an idea or concept and symbols. (comment by Sabina Ndiung, DIKDAS 2007)
