CONSTRUCT THE IDEAS IN MATHEMATICS LEARNING


Idea means a design that is arranged inside a human mind, can include opinion and ideals. Construct means build, helping to improve something. Construct the ideas means helping to improve a design that arranged in a human mind that makes a real idea.
Basically the idea is not easy to build. Moreover, developing ideas in mathematics learning. Not as easy as we imagine. In solving mathematical problems there is need for the development of ideas that allows us to solve the problem. Before we begin to work on problems in mathematics, we must understand a few important steps before we start.
First, we have to develop ideas related to the problem. This is useful to find all the possibilities that will appear when we solve the problem such as a double meaning or a hidden purpose in it. Developing an idea related a problem, never make us doing wrong the steps in our works.
The second is crafting ideas that have been developed into a draft of mind. So it becomes a whole design idea. Through constucting the ideas we can determine which steps we will take to resolve the problem.
Next is to solve the problem. In solving the problem, we can use the design idea that was conceived and developed before so that we'll find easier way to find the right answer.
By using the steps above, hopefully we can solve Mathematics problems better and  get a correct answer. In learning mathematics the most important is the process towards the right result, not on the final result regardless of the process. The processes that we do, can build our own ideas and can build up our knowledge. This process will add our experience in solving the math problems correctly. So that we build a world, ideas, and knowledge of our own without realizing it. And it would be easy to stick in our minds than solve out the problem without regard to the process.
In Indonesia, mathematics learning still focuses on teachers, so that students only be described as an empty barrel that every day continues to be filled and refilled. Students are difficult to grow, especially in developing their ideas, because every day they just accept, never do something.
Then, learning system in Indonesia is too open minded, still searching for the identity. So that the teaching methods sometimes adopted from other countries.
In mathematical problem solving in Indonesia, is still dominated by the teacher. Because they assumed that teachers teach as a professional obligation in accordance with government regulations and have to achieved all learning indicators of competency standards that have been applied.
However, many schools are implementing student center. Student center is a method of student-centered learning, students become a major role in the learning process, and the teacher only as a facilitator who facilitates the students when faced with learning difficulties. By applying this method of student center, students are expected to be able to develop ideas and construct their own ideas to solve mathematical problems according to their ability and their own way. Teachers are not allowed to impose a method to students. That way they can build their own knowledge, without being forced.
In Japan, the mathematical problem solving do not know "contstruct". They do not construct ideas before solving problems, but they are directly to solving the problem. It is can be said that students can not develop properly. Besides that, problem solving is also used as a character study. So that learning becomes semi-authoritarian and contstructivis not go well. Students are not given the opportunity to build their ideas and solve problems in their own way, so here the teacher took a leading role in the learning process. It is also influenced by the culture in Japan too.
While in Australia, they applied Mathematical Modelling method. Mathematicals modeling is a method of learning mathematics that uses models as a tool in the learning process. This method is used for teaching mathematics in primary schools. Due to the use of models or props students will be more easily aroused and easily capture the point that the teacher has been submitted. This model will facilitate students in learning mathematics. They can develop their skills by using models or learning aids.
According to Max Stephens, models used in the learning of mathematics should be varied and not monotonous, so students are more interested and not get bored Modelling problems need to be designed so that multiple solutions of varying mathematical sophistication are possible and such that students with a range of personal experiences and knowledge can participate In this way, the mathematical experiences of students become more challenging, authentic and meaningful.
. A good teacher in the learning does not focus on text books. Rather they should be able to develop a medium of learning for students. Learning mathematics in pattern-making is required. Because the pattern gives us the ability to find something we have not understood so that we can understand the meaning of the pattern. Involvement of students in the learning process of mathematics provide more knowledge and experience for them. So that they can easily capture the intent conveyed.
Mathematics can not be separated from the numbers. The number is mathematical knowledge. Function of the numbers is to measure the quantity, to decide, to the make something more specific, make a definition. Number is one of the pattern. The number is also often used to construct the problems in mathematics.
As a teacher we need to rationalize in teach mathematics to the students. It’s means that we have to be able to explain the phenomenom of mathematics education as a reference in teaching mathematics. Teacher personality is desperately needed in teach mathematics in class. Because teacher personality in teach mathematics is very influental to the students’ mental developing.
In addition, in constructing the ideas, teachers also need to know about the theories and international paradigm in learning mathematics. So that they can apply them appropriately in learning process at school. Teachers also must be able to see the difference between students' competence, so that they can deliver the right system to their students. Cultural differences are also very influential in the teaching of mathematics in schools.
Mathematics has links with the science of religion. Some concepts in mathematics are also used for religious purposes such as the construction of a Borobudur temple in Central Java, the level and shape are using the concept of a complex geometry and the construction is perfect. Religion has the highest position in life. It is effective if religion and mathematics knowledge can runs together and ballance.

PROBLEM IN DEVELOPING INTERNATIONAL LEVEL OF TEACHING LEARNING OF MATHEMATICS



In the era of globalization and the increasingly sophisticated technologies require an individual to have different abilities and skills more than other. Not only in economic or cultural course, but also education is very important. Creativity and problem solving skills are very necessary in the face of this globalization era. One means to improve the creative and problem-solving abilities in the field of education is through the learning of mathematics. However, the learning of mathematics were frequently encountered problems. Some problems in developing an international level of teaching learning of mathematics are as follows:
-          Low competitiveness at the international level, for example in the Olympics
-          The low average value of UNAS (National Final Exam)
-          The low interest in learning and achievement among students learn mathematics
-          Submission of material that is less attractive from teacher to student
-          Low quality studies supporting books
Some of the above are examples of common problems in developing an international level of teaching learning of mathematics.
Problems of low achievement and student interest in learning math because Mathematics learning in Indonesia is still dominated by the exercises are basic. It is not go into mathematics as a whole. Most teachers only explain a mathematical concept which only emphasized the importance of numeracy skills, algorithmic steps, and the memorization of formulas. This is why the students only get the basics mathematical skill.
If we linked to the internationalization of mathematics education, the achievement of basic skills is not enough. Mathematics learning, now and in the future, can not rest only on achieving basic skills, but instead should be designed to achieve a high level of mathematical competence (Parwati: 2008). If the teacher is still at the stage of explaining mathematical basics skills course, students most likely will just remain there.
In this globalization era as much as possible the teacher should be able to answer a variety of challenges at the international level. If the teacher remains at its foundation, traditional in nature, how they can develop and compete internationally. How could they make competent students in mathematics?
The next problem is the lack of teachers’ creativity in teaching. Most teachers are still fixated on the available curriculum. They only teach what is written in the syllabus. Most of them seldom add material that is actually very important but not listed in the syllabus.
Lack of teachers’ creativity in teaching demonstrated in the number of teachers who are still fixated on the material in the textbook for teaching materials. It also resulted in the ability of teachers to provide a question in the test. They are still hooked to the textbook. As a result, they give a question for test similar to the examples problem in the textbook. Furthermore, in providing a mathematical problem, teachers often assign only one correct answer. In addition students are also required to answer the questions given in accordance with what has been previously demonstrated by the teacher.
The above shows the teaching-learning process is still teacher centered. Teachers still dominate the teaching and learning activities. Also according to Marpaung (in repository.upi.edu) students are almost never given a chance to try out their own strategies to solve problems and the teacher did not dare to take decisions that are in the interest of the class curriculum. It can be concluded that the learning of mathematics in schools still require innovations that demands creativity of teachers in improving learning strategies.
Learning process in schools should be used students centered system. Here the teacher is not as central to the learning process, the teacher only as a facilitator and dynamic factor. All processes should be centered to student learning. Students are faced with a problem and they are required to complete it in accordance with their own creativity. Many ways and methods that can be develop creative skills in learning mathematics. One way is to apply the learning model based on creative problem solving. This learning model is expected to be able to nurture creative skills and problem solving skills through the habit of thinking and being creative in understanding and solving mathematical problems. In the end the habit of thinking and being creative will have a positive effect on student behavior in the face of their daily lives (repository.upi.edu : 2009). One way to improve the creativity of students in the study is to provide an open-ended problem. The presentation of open-ended problems will be able to train students to think of creativity as a problem presented requires students to think about the possibility of correct answers (Shimada, S., 1997).
The next problem is the lack of books for math investigations. Most of the books in circulation has a very low quality, because many books were written by people that do not involve a skilled person in mathematics education or mathematics teacher. As a result of the outstanding books do not meet the qualifications specified by the school. So,  a teacher  needs to develop students worksheets or LKS. LKS contains a summary of the material and practice questions that are routinely made ​​by the teachers themselves. By making the exercises by their own, teachers can determine the levels of difficulty of the questions that correspond to the ability of students. By using LKS,  a teacher could develop questions that are open-ended problem that not only to measured students' ability to calculate, but  also hone their creativity.  The books such as those described above can be used as a complement to learning (Parwati, 2008).
Developing competencies in creative thinking among students is very important in this era of global competition, because  the complexity of the problems in all aspects of modern life is increasing. Ability to think creatively considered a high order competencies  and can be viewed as a continuation of basic competence (commonly referred to as learning basic skills in mathematics) (Sudiarta: 2010).
