Pendekatan realistis bermanfaat untuk mengajar konsep pecahan yang dapat di sediakan oleh guru. Mengembangkan materi model konsep pecahan, siswa perlu mengembangkan hubungan antara model bahan. Banyak strategi dan praktek telah diciptakan untuk  mendorong konsep pecahan.

Guru membawa banyak pemahaman informal untuk usaha mereka dalam  mengembangkan model mengajar pecahan. Dalam mengembangkan model dari mengajar, para guru diharapkan bahwa ada kecenderungan bahwa siswa mereka akan mempertimbangkan tidak hanya sebagai angka, tetapi juga proporsi atau bilangan rasional. Meskipun, Model memperkuat siswa untuk membangun konsep mereka sendiri dari pecahan, masih ada kesulitan bagi siswa untuk memecahkan masalah diungkapkan secara simbolis. Namun, mereka mampu untuk memecahkan masalah yang sama diungkapkan dalam konteks situasi dunia nyata. Sebagian guru mengakui bahwa representasi dari pecahan bisa menjadi tugas yang sangat abstrak dan sulit bagi siswa.Sementara itu, mereka juga menemukan bahwa model pembelajaran adalah pendekatan yang sangat penting dan berguna untuk mengajar pecahan di SMP.

 Utilizing the facilities in Microsoft Office 2007, we can develop a learning medium geometry in junior high. Media learning geometry in junior high is an implication of the translation Standard Competence and Basic Competence is related to the ability of geometric, as follows:

1.      Understanding the relationship line to line, line with an angle, corner angle, and determine its size

2.      Understand the concept of a rectangle and a triangle and determine its size

3.      Using the Pythagorean Theorem in problem solving

4.      Determine the elements, the circle and size

5.      Understanding the properties of the cube, beam, prism, pyramid, and their parts, and determine its size

6.      Understanding unvarying flat wake and its use in problem solving

7.      Understanding the properties of the tubes, cones and spheres, as well as determine its size.

Skills to wake up the foundations of geometry using Microsoft Word 2007 facilities can be developed to make the wake-up more complex geometries, such as wake-up 3-dimensional geometry. Skills can be enhanced to study aspects of the geometry with a higher standard of competence, for example, to determine the value of phi.

·         Use of Microsoft Word 2007 is easy to do by the teacher because the software is contained in almost every new computer generation.

·         Use of Microsoft Word 2007 will add to the motivation and pleasure in learning geometry.

·         Students can use Microsoft Word 2007 to study the geometry either independently or through collaboration.

·         By using Microsoft Word 2007, students can conduct an investigation or inquiry of geometry concepts.

·         By using Microsoft Word 2007, students can perform activities of problem solving or mathematical problem solving.

·         By using Microsoft Word 2007, students can communicate the results to both the teacher and to other friends.

UNIVERSITAS NEGERI YOGYAKARTA MENUJU PERGURUAN TINGGI BERTARAF INTERNASIONAL (PTBI) “Yogyakarta State University on the move toward World Class University”By Dr. Marsigit, MA

State University of Yogyakarta leading international universities can be given meaning through two approaches to think that a formal approach and substantive approach. Formal approach UNY position in the life of promiscuity among the many universities in Indonesia, interactions among universities in the world, and particularly the role as a former LPTKs UNY. UNY main task is to print the educational staff and develop a science education and science teacher, in addition to print non-academics and professional education. Perspective of the global era is not only penetrated the field of education alone but has to reach all aspects of life. In the midst of euphoria to the international level, UNY presented to two phenomena that spans the two sides / ends that have not synergistic. First, UNY have an obligation to support government policy to develop the schools SBI / RSBI, and thus the UNY must also take steps towards an international university. Second, UNY presented to the various criteria for ranking world universities, and in fact UNY still far from the ranks.

Things that need to be considered for UNY to WCU:

1.      The ability of English lecturer in international class still needs to be improved

2.      Students need to be given wider opportunities to improve English skills

3.      Explored and developed the need for more intensive to establish cooperation with partner universities

4.      The need to fill or follow the MOU has been agreed with partner universities.

5.      For professors still enhanced ability to research and publish research results in international journals

6.      Existing information systems still need to be improved, including the development of bilingual Web

7.      The need for increased frequency of communication or cooperation between lecturers UNY with faculty partners.

8.      Realized the need for joint activities (joint activity) either individually or institutionally.

9.      The need for support facilities and administrative staff to support the activities of WCU

10.  The need for support and understanding among all UNY in looking at the need for WCU

11.  The need for communication and socialization are constantly about the nature, direction and purpose WCU

12.  The need for formal support and foundation of the university on the development of UNY to WCU.

Education has a very important role in the process of improving the quality of human resources. Therefore, education is expected to be one vehicle to prepare the nation's generation, so the birth of human resources that are reliable and have the ability to face the dynamic development of science and technology today quickly, accurately and effectively. These developments also affect a competency to be developed by educators (teachers) include:

·         Competence to develop methods of discussion, between teachers and pupils and between pupils and students, methods of problem solving (problem solving) and the method of discovery (investigation).

·         Competence of teachers in the development of realistic mathematical approach include: the use of the real world to explore mathematical concepts, the formation of mathematical concepts, mathematical knowledge builders, as well as develop in the form of a formal abstract mathematics.

·         Competence development of teachers in the field of mathematical thinking attitude, include: trying to ask, trying to understand a mathematical problem, trying to find a mathematical problem, try to solve mathematical problems, trying to link mathematics with each other, trying to use the data to solve the problem, try to record & communicate problem-solving activities, trying to manage & develop mathematical objects.

·         Competence development of teachers in the areas of problem solving activities which successfully developed include: making math relevant to / be able to explore the mathematics of everyday life - the day, able to use mathematics to solve everyday problems, able to use various sources of learning, the idea / problem-solving ideas are pure or derived from his own experience, able to solve mathematical problems or issues, and translate the mathematical problem.

·         Competence development of teachers in the field of mathematical thinking method is successfully developed include: inductive thinking, analogous thinking, deductive thinking, integrative thinking, thinking developed, abstract thinking, thinking simplify, make conclusions, think about a special case, using the symbol, and use statements with numbers , quantity and images.
