CHAPTER I
INTRODUCTION

A.      Problem Background
Education is one of the efforts to develop and improve qualified human resources, as suggested by Naisbitt (in Tilaar, 2002:116) "Education and training must be a major priority; they are the keys to maintaining competitiveness ". Based on research conducted Son (2007:15), one an effort that can be done to improve the human resource is improve the quality of education that focuses on developing the ability to think students. Meanwhile, critical thinking, creative, systematic and logical can be developed through mathematics education. It is very possible because mathematics has structure with a strong and clear linkages with each other and mindset consistent (Depdiknas, 2003). One characteristic of mathematics is posted have abstract objects. This abstract nature causes many students experience difficulties in mathematics. Mathematics achievement of students both nationally and international not encouraging.
One cause of low student math achievement is mathematics learning because students have not significantly, so that students' understanding concept is very weak. Jenning and Dunne (1999) said that, most students difficulties in applying mathematics to real life situations. Teachers in the classroom learning does not associate with a scheme that has been owned by the students and the students are given the opportunity to rediscover and
construct their own mathematical ideas. Linking real life experience of children the mathematical ideas in the classroom is important for learning significant (Soedjadi, 2000; Price, 1996; Zamroni, 2000). According to Van de Henvel-Panhuizen (2000), when children learn mathematics apart from their everyday experiences, children will quickly forget and can not apply mathematics. Teaching and learning process generally take the class where the teacher interacts with students, it can be ascertained that the success of the learning process is very dependent on what is done and what model is used by teachers as Sukmadinata opinion (2004: 194) which states that "no matter how good the curriculum (official) results are very depends on what teachers do in the classroom (actual) ". One model oriented mathematics learning mathematics everyday experience (mathematize of everyday experience) and apply mathematics in everyday life today is learning Realistic Mathematics (RME). Learning first RME developed and implemented in the Netherlands and is considered very successfully to develop students' understanding and ability to think.

CHAPTER II
DISCUSSION

A.  Realistic Mathematics Education (RME) model
According Zainurie (2007) realistic mathematics is school mathematics performed by placing the realities and experiences of students as a starting point of learning. Realistic problems are used as the source of the emergence of mathematical concepts or formal mathematical knowledge. Realistic mathematics learning in the class-oriented on characteristics of Realistic Mathematics Education (RME), so students have the opportunity to reinvent math concepts or formal mathematical knowledge. Furthermore, students are given the opportunity to apply mathematical concepts to solve everyday problems or problems in other subject.
Realistic Mathematics Education (RME) is a theory of teaching and learning in mathematics education. RME theory was first introduced and developed in the Netherlands in 1970 by Freudenthal institutes. This theory refers to the opinion Freudenthal (in Zainurie, 2007) which says that mathematics should be related to reality and mathematics is a human activity. This means that mathematics should be close to the child and relevant with real life everyday.
In learning through realistic approaches, the strategies of student information develop when they solve problems in usual situations that have been mastered, and the circumstances that maked the starting point of learning realistic approach. Realistic Mathematics Education (RME) was also given a sense of "how to teach by providing opportunities for students to investigate and understand mathematical concepts through a problem in a real situation." (Megawati, 2003: 4). It is intended that learning meaningful for students.
Soedjadi (2001: 2) argues that learning realistic mathematics is essentially realistic utilization and environmental which understood by students to facilitate the learning of mathematics, thereby achieving the goal of mathematics education is better than in the past. What is meant the reality is the real things that can be observed or understood by learners, while is the environment is the environment where learners are well within the school, families, and communities to understand the learner. Environment in this case is called everyday life. So it can be said that the Realistic Mathematics Education (RME) is an approach learning that uses everyday problems as a source of inspiration in the creation of concepts and apply these concepts or can be said a math learning based on real things or real for students and refer the social constructivist.
According Gravemenijer (1994:90) that the principles of realistic mathematics learning is:
a.    Guided discovery and progressive math (guided reinvention and progressive mathematizing).
     Through the presented topic, students should be given the opportunity to undergo the same process as math concepts found. This is done by providing contextual issues that have a variety of possible solutions, followed by mathematics. The learning process is set in such a way that students find their own concepts or results (Fauzan, 2001: 2).
b.    Phenomena that are educational (didactical phenomenology)
This principle emphasizes the importance of contextual issues to introduce math topics to students.
c.    Developing models (self developed models)
While working on contextual problems students develop their own models. The models are expected to change and lead to a better form that leads to the formal mathematical knowledge, so expect the following sequence occurs "contextual problems" → "model of the contextual issues" → "model towards a formal" → "formal knowledge" (Soedjadi, 2001: 4)
According to Treffers (in Zainure, 2007: no page) The characteristicsof RME :
1.    Using a real-world context, bridging the mathematical concepts with everyday experience of children. Meaning in mathematics learning environments realistic daily or knowledge that the student may be used as part of a contextual learning materials for students.
2.    Using models, which emphasizes the informal resolution prior to using formal methods or formulas.
3.    Using the production and construction, by making free production students are encouraged to reflect on the part they think is important in the learning process. Informal strategies of students in the form of contextual problem-solving procedure is a source of inspiration in constructing formal mathematical knowledge.
4.    Using interaction, explicit forms of interaction in the form of negotiation, explanation, justification, agree, disagree, question or reflection is used to achieve a formal form of informal forms of students.
5.     Using the related, structure and mathematical concepts are interrelated, and therefore the relationship the integrated between the topic (unit of study) should be explored to support the learning process meaningful.
B.  Steps Realistic Mathematics Learning
Based on the characteristics of RME as well as taking into account the opinion noted above, it can be prepared a step-by-step learning approach that RME is used, as follows:
Step 1: Understand the contextual issues
The teacher provides contextual issues in everyday life to students and ask the students to understand the issues, and to provide the opportunity for students to ask for an issue that is not yet understood. Characteristics RM E that appears in this step is the first characteristics which uses contextual issues as a starting point in learning, and the interaction of these four characteristics.

Step 2: Describe the contextual issues
If the students have difficulty understanding the problem, the teacher explained the circumstances of the matter by giving instructions or in the form of suggestions as needed, limited to specific parts of the problem are not yet understood.

Step 3: Solve the problem
Students describe the contextual issues, interpretations of existing mathematical aspects of the problem in question, and think about problem-solving strategies. Furthermore, students work to solve the problem in its own way based on its prior knowledge, making possible the settlement of differences with each the other student .Guru observing, motivate, and provide limited guidance, so that students can obtain the settlement issue. RME characteristics that appear in this step is to use the characteristics of both models.
               
Step 4: Compare the answers
Teacher asks students to form groups to work together to discuss the solution of problems that have been solved individually (negotiation, compare, and discuss). Teachers observe student activities, and provide assistance if needed. Characteristics PMR appears that the interaction
                                
Step 5: Conclude
From the discussion, the class, the teacher directs students to deduce a formula concepts / principles of the topic being studied. RME characteristics that appear in this step is the interaction between students and teachers.
               
C.      The Advantages and Disadvantages of Learning
Some advantages of realistic mathematics learning include:
1.    Lessons to be pleasing to the students and did not seem tense.
2.    The material can be easily understood by students.
3.    Props are objects that are around, so it is easy to get.
4.    Teachers are challenged to learn the material.
5.     Teachers become more creative in making props.
6.    There are relevance and usefulness of mathematics in everyday life.
7.    Students find their own mathematical concepts with the help of teachers.
                                
Some disadvantages of realistic mathematics learning among other things :
1.    Difficult to apply in a large class.
2.    It takes a long time in the learning process.
3.    Efforts to implement RME requires a very fundamental about the various things that      are not easy to put into practice.
4.    Implementation issues are eligible RME is not always easy for every topic that needs    to be studied mathematics students.










CHAPTER III
CLOSED

A.      Conclusion
Based on the description above, then the conclusion can be delivered a few things. Math is realistic school mathematics performed by placing the realities and experiences of students as a starting point of learning. Furthermore, students are given the opportunity to apply mathematical concepts to solve everyday problems or problems in other fields. In other words, learning oriented mathematics realistic matematisasi everyday experiences and apply mathematics in everyday life, so that students learn the meaning (sense).
Realistic mathematics learning centered learning, while teachers only as a facilitator and motivator, so it requires a different paradigm of how students learn, how teachers teach and what is learned by students with math learning paradigm for this. Therefore, changes in the perception of teachers about teaching needs to be done if you want to implement a realistic mathematics learning.
B.       Suggestion
In accordance with the conclusions above, it is recommended:
1.      The experts or lovers of mathematics education to conduct research oriented mathematics learning of social realism in accordance with Indonesian culture.
2.      Mathematics teachers to try pengimplementasikan realistic mathematics learning in stages, for example, began by providing realistic problems to motivate student expression.
