The results of the action showed that: (1) at first cycle, the average of the students’ score obtained within the learning achievement test was  73,32 of an ideal score 100 with standard deviation 17,775 in which 20 of 31 students or 64,5% satisfied the individual mastery which showed that the classical mastery wasn’t attained; (2) at second cycle, the average of the students’ score obtained within the learning achievement test was  82,10 of an ideal score 100 with standard deviation 10,486 in which 28 of 31 students or 90,3% satisfied the individual mastery which showed that the classical mastery was attained; (3) for quality of process it covered three indicators: a) from first cycle to second cycle, in terms of student activity is seen that students are increasingly active in the learning process, b) motivation of students is also increasing every meeting of the cycle I to cycle II, c) In terms of student interest as seen from two aspects, namely affective and cognitive development has also increased. Base on research which was conducted, it can be conclude that quality of learning both quality of result and quality of process increase through Realistic Mathematics Education (RME) approach with cooperative learning setting Team Assisted Individualization (TAI) type.

INTRODUCTION

A. Background

Mathematics as one of the core subjects in school plays an important role in the mastery of science and technology. This is because mathematics is a means thinking logical, symmetrical and critical. Based on the above description, the existence of mathematics is needed so that further effort is how the mathematics that can be learned, known and understood until it can be applied by everyone in daily life. One characteristic of mathematics has an abstract object of study. Characteristic of abstract causes many students experience difficulties that could affect the quality of learning mathematics.

The quality of learning includes quality of process and quality of results (Asti, 2007). Improving the quality of process can be observed from the increased interest, motivation and activity of students in each learning (Paduppai, 2004: 188).

Conditions of mathematics instruction that have been developed experienced by schools both primary and secondary education, including on SMP Negeri 1 Bulukumba especially class VII.4. Data of final test results odd semester academic year 2010/2011 after which averaged with mastery learning outcomes on an individual basis only 9 from 31 students.

One of the mathematics learning which oriented mathematize of everyday experience and apply mathematics in daily life is Realistic Mathematics Education (RME) approach.

One of the learning models that support this realistic approach is cooperative learning models. Cooperative learning models over placing students as subjects in the learning process, so that teachers more act as facilitators and provide the opportunity for students to interact with each other in completing the tasks it faces (Suradi, 2003).

One of the types of cooperative learning models is TAI (Team Assisted Individualization). TAI method can easily be used in mathematics class, and it combines cooperative goals and tasks with a high degree of individual accountability (Slavin and Cooper 1999). This method was used because it has simple procedures that are easy to understand, remember, and apply. In adaptation to individuals, TAI adapts to students’ individual needs. (Tarim, 2007)

Based on the description above, researcher feel need to conduct classroom action research. Therefore, the author is motivated to conduct research under the title “Improving the Quality of Learning through Realistic Mathematics Education (RME) with Cooperative Learning setting type Team Assisted Individualization (TAI) at topic of Quadrilaterals and Triangle on grade VII Junior High School 1 Bulukumba“.

b. Observations Result of Learning Processes

1. Active Students

At the first meeting, students don’t do unit tests on an individually. At the third and fourth meeting is self-arising awareness of each student to take units tests in their own although the increase is not significant. Students who double checks his friend’s answers appear at the first meeting are still confused what they should do. At the second meeting until the fourth meeting students who perform checks already familiar with their duties, they check the work of his friend though still annoying friend who was working on unit tests.

2. Student Motivation

a)        Increasing students’ attention to the explanation of teachers increased although not significantly.

b)        The emergence of enthusiastic students, who want to know more about the subject being studied

c)        The involvement of students in teaching and learning mathematics is increasing.

d)        The emergence of the seriousness of the students in learning mathematics in which students who correctly answer practice questions that are given more and more

3. Student Interests

a)        Cognitive Aspects

At the first meeting of the first cycle is still not a lot of students who pay attention to learning, many students who are not active in the group. Curiosity of students is still less, is marked by enthusiastic students in asking about the learning materials are lacking. At the fourth meeting of curiosity pupils more increase, is characterized by the more questions asked of students.

b)        Affective Aspects

At the first meeting student environment less pleasant, because the division of groups of students are still noisy. There are many students who perform other activities and less active resulting in the classroom atmosphere is less fun. But in the next meeting until the end of the first cycle in the classroom environment more pleasant, indicate the interaction between teachers and students, so that conditions of class become quite active and quite fun.

b. Reflection

In general, the student enjoys and looks quite interested and motivated in mathematics lessons with a realistic approach, because the material to students always presented are related to real situations in daily life. Also, by setting the working group TAI type used to make them to exchange ideas so that learning mathematics can be done with a relaxed, enjoyable, and meaningful even if in the first cycle is still there are some students who passive.

c. Decision

Because mastery learning students as well as interest, motivation and activity of students have not shown that optimal results then this is the reference to continue the implementation of actions to Cycle II to seek improvement through Realistic approach through group work setting type TAI with more encouraging students to be more active in teaching and learning process.

2. Cycle II

a. Description of Results Obtained after the Implementation Actions

After the implementation of the action taken on the second cycle, students’ learning results are obtained as follows:

From the table 4.4 above we can see that 90.3% students or 28 students included in the category and 9.7% completion students are included in the category no means exhaustive, there are 3 students in need of repair. This shows that the results of research conducted by researchers from the cycle I have a very significant increase in Cycle II.

b. Observations of Learning Processes

1. Active Students

At the beginning of the meeting on the second cycle, activity of students has been good enough. Many students ask the teacher about the topic and the average student was able to give examples of the material in daily life. Likewise at a second meeting until the end of the meeting on the second cycle is greatly increased.

This second cycle students taking the units test individually at every meeting, while students are in charge of checking the answer to his friend is doing its job properly. Compared with cycle I, in this second cycle the activity / active students in the learning process much improved. Students compete to comment on the answers of other groups and students are also vying to make inferences about the material already learned.

2. Student Motivation

a)      Increasing students’ attention to the explanation of teachers has increased from cycle I to cycle II.

b)      Enthusiastic students who want to know more about the subject being studied is also increasing

c)      The involvement of students in teaching and learning mathematics is increasing.

d)      Students can link learning content with which he is doing or thinking in dayli life also increased from cycle I to cycle II.

e)      Enthusiastic students in doing worksheet increases.

f)        In the first cycle students have 2-3 people who can demonstrate the benefits of learning materials for some of his friends.

g)      The emergence of the seriousness of the students in learning mathematics in which students who correctly answer practice questions that are given more and more and increases from cycle I to cycle II.

3. Student Interests

a)      Cognitive Aspects

At the first meeting of the second cycle has increased students’ attention on learning, as well as in the second meeting until the end of a meeting in the second cycle is increasing. Curiosity of students is very high, is marked by enthusiastic students ask questions about material in the learning higher.

Students also been active in the group and pay attention to things that are delivered by teachers in this case is researchers. Information needs of students will also greatly improved, marked by the increasing number of students who are able to explain the benefits of learning materials with daily life.

b)        Affective Aspects

At the first meeting of the first cycle students are less pleasant environment, due to the division of groups of students are still noisy. In this second cycle students’ environment has become conducive and comfortable. Students who perform other activities had gone down and down until the end of this second cycle. Students are more enthusiastic in participating in learning. Interaction between teachers and students is also increasing, so the condition of the class became very active and very enjoyable.

c. Reflection

In general, students liked and looked very interested and motivated in math by applying RME approach to setting cooperative learning TAI type. At the end of this Cycle II implemented the final test. In doing so, they demonstrate readiness in the test. This can be seen when the questions they are distributed fairly quiet and they did with gusto even though there are those who find it difficult because they do not learn. Besides the activities push away the task of friend is no longer because they were given more emphasis to the students as well as to tighten supervision.

d. Decision

Of the two cycles that have been implemented by using RME approach with setting cooperative learning TAI type obtained the following results:

1)      Active, interest and motivation of students is increasing

2)      The completeness of students studying mathematics has increased significantly.

B. Discussion of Research Results

Increase in the average result of learning mathematics from Cycle I to Cycle II, which is 73.32 in the first cycle increased to 82.10 in the second cycle. skewness from cycle I to cycle II was also negatively skewed indicating that many students who earn high grades. In addition to the standard deviation and variance decreased from cycle I to cycle II show that learning through RME approach with cooperative learning setting type TAI  which done to make students become more homogeneous.

In terms of completeness of individuals also increased where the number of students who did not complete the study in cycle I and be completed in Cycle II, as many as 9 people, or an increase of 29.03%. The number of students who completed their study results in cycle I and cycle II remains fully in as many as 19 people or 61.29%.

From the results of the qualitative analysis found that the quality of the learning process by setting the RME approach with cooperative learning setting TAI type of cycle I to cycle II is also greatly improved. In terms of student activity is seen that students are increasingly active in the learning process. The existence of the driving factors for students learning mathematics among to get a high score both groups and individuals so that students are very enthusiastic in learning mathematics, as well as more attention to the lesson.

In terms of student interest as seen from two aspects, namely affective and cognitive development has also increased. Viewed from the aspect of cognitive, attention and curiosity of students from cycle I to cycle II greatly increased is evident from the increasing number of students who ask about math. Viewed from the affective aspect is meant learning environment of students. Interaction between students and teachers are also on the cycle I to cycle II increased the number of students which demonstrated respond or questions in the classroom learning so that the condition becomes very active and very enjoyable.

With the increasing level of activity, motivation and student interest in teaching and learning are also accompanied by an increase in the completeness of study or in other words, quality process and quality of results from cycle I to cycle II, it can be said that learning through RME approach with cooperative learning setting TAI type can improve the quality of learning mathematics.
