Realistic Mathematics emphasize on construction from concrete things as initial point for student for getting mathematics concepts. Analysis about teaching learning methods using VTR (Video Tape Recorder) is one way or effort that can be done by the teacher. With using VTR, teacher hoped can learn how make a plan to teach mathematics in Junior High School, how to develop the learning source, how to develop assessment activity, and how to implement teaching learning process that suit with Realistic Mathematic Education(RME) in Junior High School.
RME has specification in approaching. In RME, student develop own model and that model is used become the base to develop their formal mathematics. There are two models that can be happen in that process: model of situation and model for formal mathematics.   
An observation and analysis using VTR, where teacher record teaching learning mathematics with realistic approach, the other teacher can test and find the other alternative for develop the idea about concrete object that can use in teaching mathematics context and built relation mathematics with social interaction.
Mathematics teaching model that have been recorded in VTR has any profit and weakness. Any profits that can get by the teacher such as: the teachers having a chance to discuss with other teacher to get new knowledge with compare with own experiences, the teacher has chance to reflect mathematic concepts, the teacher has many reflection about planning teaching learning process, source of learning and also an assessment that have been get from the other teacher, etc. But VTR also has weakness such as: limited point of view, can’t record all aspect, result (picture) quality, and moment that can’ always appropriate.

PENDEKATAN MATEMATIKA REALISTIK PADA PEMBELAJARAN PECAHAN DI SMP

By: Dr. Marsigit, M.A. Reviewed by: Kholida Agustin As we know, that realistic mathematics emphasizes to construct the context of concrete thing as first point (impression) for the student to get the concept of mathematics. The concrete thing is manipulated by the student to support the students’ effort in change the concrete thing to abstract one. The student need to given a chance so they can construct and product mathematics by their own language. The standard competence in junior high school that related with fraction learning has the aim to make the student understand about operation properties and how to use it to solve the problem. The development of realistic problem that related with the fraction form such as the fraction and its form, simple fraction, change the fraction that numerator bigger than denumerator become “campuran” fraction, compare the fraction, order the fraction, etc. Reflect from that activity so in the learning fraction by learning mathematics r...

KEGIATAN PENELITIAN SEBAGI USAHA UNTUK MENINGKATKAN PROFESIONALISME GURU MATEMATIKA

By: Dr. Marsigit, MA Reviewed by: Kholida Agustin   Research can be define as an activity to get knowledge, were done by certain procedures that systematically and support by methodology. Teacher as researcher can make a change in mathematics teaching learning in the school by various experiments, so it has result science method. Truthfully, contemporary mathematics education research is mathematics research education that the researcher have awareness about how important understanding truthfully of mathematics, mathematics in school, mathematics education, learn mathematics theory, etc. The view about the truth and mathematics character in school will give whole characteristic of mathematics. It has assumed that there are still many students that not like mathematics. There are some characteristics of mathematics such as: pure mathematics, applied mathematics and mathematics in school. In order to develop student competences, assumption about the student characterist...

MATHEMATICS TEACHING ACROSS MULTICULTURAL CONTEXT

By : Kholida Agustin (09301241011) Department of Mathematics Education, Faculty of Mathematics and Science, Yogyakarta State University A.     Introduction   A Mathematics still becomes scary subject for student. Improper teaching method that used by the teacher make student confuse and not have any desire to learn mathematics further. The students are prosecuted to always develop their knowledge and their ability in mathematics. On the other hand, the teacher also prosecuted to improve their teaching skill. There is opinion, “if we want to improve the student’s ability, we must improve the teacher skill first”. This opinion should be advice for the teacher to become better teacher in the future. Teaching mathematics in school should be has suit approaches to make the student improve correctly, suit with world development. The development of technology makes this world feel tighter. The student can learn by their selves by other friend or ...
