VISUAL THINKING AND MATHEMATICAL PROBLEM SOLVING OF THE NATION CHARACTER DEVELOPMENT

Mathematical problem solving is the heart of mathematics and visualization is the core of solving mathematics. Visual thinking is the most effective and powerful in mathematics instruction. The way we learn, and then remember, sustaining a strong relationship with the way our senses operate solve math problems. Schools have the freedom to manage and choose approach to learning mathematics. How can character education is taught to students and therefore will have the opportunity to emphasize the special character of the school. While each school has the freedom to choose the kind of values ​​that, for nation building must have some values ​​taught in every school. Those values ​​must be the most important value to support the Indonesian nation-building project. First, multicultural values. Indonesia consists of various ethnic, religious, and cultural. If the nation wants to be stronger in the future, we must accept differences between us. Without accepting the differences, we will easily slip into fights and conflicts. The spirit of multiculturalism and religious diversity would encourage all people to accept others as members of the Indonesian nation. This is the spirit of Bhineka Tunggal Ika: although different, but still one. We sometimes lack of respect that spirit. Some of us want to impose our ideas on others Second, honesty. One important reason why corruption is very difficult to be eradicated in Indonesia is the lack of honesty. Most of us are not honest anymore. The spirit of honesty in the learning of mathematics must be inculcated in school. Students should learn about the value of honesty and implementation. Students must learn to be honest in school, to be honest with yourself, honest with others, be honest with their life and honest about what they do. Students should be honest when completing math problems, tests and national exams.Third, learn to obey the law.
