Learning Mathematics which had usually been dominated by teachers with evaluation form that was having more oriented in result was less in giving the opportunity for students to improve their capability in learning process, in this case teacher was becoming a focus and source in learning. That was caused by the less learning of the schools that were focused on teachers. Mathematics lesson for all students formerly was frightened lesson, so that students were dislike it. Learning Mathematics needs some aspects to support the learning process, they are formal reasoning level and positive attitude of students. Therefore, it needs to find the alternative learning that can improve studying activities, and gives the opportunity for students for more active in studying. Learning approach of realistic Mathematics is one of the alternative learning to improve student’s creativity in learning Mathematics, so the formal reasoning of student’s is getting increase.
This research is the experimental in studying at SMP Negeri in Pematangsiantar on North Sumatera province, they are SMP Negeri 6 and SMP Negeri 9 are taken as the population subject and as the sample of the study each of VIII.2 and VIII.3 classes in SMP Negeri 6 while VIII.2 and VIII.4 in SMP Negeri 9 as the research sample. This sample is selected with randomly from these schools for all class VIII in SMP Negeri 6 gets 6 classes while in SMP Negeri 9 gets 7 classes. This research is focused on mastery concept through increasing of reasoning formal, students activities, and the response of students toward the studying with learning approach of realistic Mathematics and many real questions in studying circle and their place.
The instruments of the research which have been needed to collecting the data in this research that consist of ability test of student’s formal reasoning in triple dimension space topic with pyramid and prism topic, the scale questionnaire of student’s attitude to know the response of students about Mathematics lesson, learning method, and many questions that have been given, and observation paper of student’s activities. Processing data is used to find the differenciate of capability of student’s formal reasoning between group of students that are getting the learning with learning approach of realistic Mathematics by using normalization gain test, statistic test that consist of normalization test (processing data is made by SPSS 15 and Exel) and presentation is done after prereguirements testing is done.
From the research result, we can conclude that student’s formal reasoning in the group of students which get the lesson with learning approach of realistic Mathematics is having the great increasing besides the group of students which get the ordinary learning (expository), the attitude of students is better (positive) when they are following the lesson by using the realistic Mathematics approach; and the student’s activities when they are following the lesson by using the learning approach of realistic Mathematics that are reflecting the active creativities, and the response of students toward the learning is getting good. The model and variety of student’s answers are more various and systematic on student’s group through. Learning approach of realistic mathematic is compared with the group of student’s whose get learning through the ordinary of mathematics approach (expository).
The learning approach of realistic mathematics is an alternative for teacher of mathematics in presenting the mathematics lesson, and the using of learning approach of realistic mathematics should to socialized in institute of schools. The using of media with the things arround the student’s environment and apply to the materials which is essential relate to the real things arround the location fo study.
