PENDEKATAN MATEMATIKA REALISTIK PADA PEMBELAJARAN

PECAHAN DI SMP

Realistic Mathematics emphasizes the construction of the context of concrete objects as a starting point for students to acquire mathematical concepts. Concrete objects and environment objects can be used as a context for learning mathematics in building mathematical connections through social interaction. Concrete objects manipulated by the student within the framework of efforts to support students in the process mathematisation concrete to the abstract. Students should be given opportunities to construct and produce mathematics in a manner and language of their own. Necessary activities so that the reflection of social activity can occur integration and strengthening of relations between subjects in understanding the structure of mathematics. According to Hans Freudental in Sugiman (2007) mathematics is a human activity and must be linked to reality. Thus, when students do activities to learn math so in her place mathematisation process.
We can examine the Numbers Break in junior high school mathematics learning through two sides of the Aircraft Numbers formal position in the context of curriculum and syllabus, and a review of substantive number rupture itself. In the curriculum development guidelines stated that in learning mathematics can be started with the introduction of a problem that fits the situation. By asking a contextual problem, learners are gradually guided to master math concepts. Competency Standards relating to learning fractions is to enable students to understand the properties of numbers arithmetic operations and their use in solving problems. With the Basic Materials of Aircraft Numbers Integer and then expected to be reached using two basic competencies are: Conducting the operation count fractions, and using the properties of arithmetic operation in problem solving fractions.
