Title :PEMANFAATAN VIDEO TAPE RECORDER (VTR) UNTUK PENGEMBANGAN MATEMATIKA REALISTIK DI SMP By :Dr. Marsigit M.A Resume by:Dessy R. Fitriyani (09313244026) Date :Friday, 23 September 2011 Blog :dessypoenya.blogspot.com Realistic mathematics emphasize on construction of concrete things context to understand mathematics easily for students especially for Junior High School. Like an statement by Hans Freudental (Sugiman: 2007), that mathematics is human activities and must be related with facts in our life. So, when the students are learning mathematics, its mean that there are mathematics process which related with their life. There are two kinds of mathematics process, (1) do mathematics horizontally its mean process how to change from the real life into mathematics symbol and (2) do mathematics vertical having definition that is the process which happen on independent mathematics system. Then, if we look at the teacher, how the teacher’s effort to get some ideas about concrete things and also enviromental object that can be used in mathematics learning process. Study and analysis about mathematics learning which recorded in Video Tape Recorder (VTR) is one of the way can be done by the teachers to develop realistic mathematics. There are many advantages that can develop teacher’s abilities by VTR. With VTR, the teachers should be learn how to make learning process in Junior High School accord to realistic mathematics principle, how to develop source of learning and also how to apply realistic mathematics in mathematics learning process. Futhermore, as a teacher should develop mathematics learning process with realistic mathematics principle, especially for students in Junior High School. There are four steps to apply realistic mathematics (Zulkardi, 2004), that is: introduction, creation and development symbol model, explanation and reason, and the last is closing or application. Four steps above must be reflected in mathematics learning process. Especially after we talk about realistic mathematics, now we talk about use of Video Tape Recorder (VTR) to develop realistic mathematics in Junior High School. As an statement by Mr. Isoda, M (2006) about the benefit of VTR is VTR (Video Tape Recorder) for teacher education and reform movement in mathematics education, specifically for developing lesson study has some benefits as: a) short summary of the lesson with emphasis on major problems in the lesson, b) components of the lesson and main events in the class, and c) possible issues for discussion and reflection with teachers observing the lesson. VTR can be applied in many chapter of mathematics when learning process, for example VTR on Geometry, VTR on fraction learning, and so on. VTR can load and show how the students discover something on mathematics learning. Moreover, VTR also can show and describe how the students apply their knowledge to make something like how to get an simple formula from the difficult formula. Absolutely, all of mathematics learning models which are recorded in VTR have excess and deficiency. So, for the teachers should discuss it to get a recent knowledge and science by compare with their experiences. Beside that, VTR also have deficiency, for example is limited on point if view, some aspect on learning process can’t be recorded on VTR, then for picture quality and shooting the picture of learning process maybe can’t focus. The conclusion is VTR can be used to develop realistic mathematics learning process by the teacher to make the students understand mathematics easily. Finally, that VTR give many advantages to the teacher in mathematics learning process.
