THE POWER OF CATEGORY AND NETWORKING

THE POWER OF CATEGORY AND NETWORKING
We live in our life and we do everything with our mind. Nothing cancelled and nothing disappears. In our mind, according to Immanuel Kant (1771), there are : qualitative, quantitative, category, relationship.
Each of them has its power to affect our behavior in our daily life. Our mind divided into two groups when it is thinking. They are top down and bottom up. Top down means that when we are thinking about something, we will think it as the general first, then we will go to the specific purpose. For example, when we thought about theorems, we will think from the theorems first. Then we will see the person who makes the theorems.
It is so different with bottom up thinking. When we thought by this method, we will think something from the specific one to the general one. We think about some complex things first, and then we make it to the simpler one. It is not easy to make something to be the simple one even though what we have been thinking about is in our real world which so complicated.
Everything that doesn’t need to think when we are thinking about something will be saved in ‘Epoch’ home. It is surrounded in our mind but when we are focus to something we looked it down or we want to think about, some other things that related to the objects but there is no use to what we have been thinking will automatically saved in there. And it is the one of the advantage we have an Epoch home because we don’t need to find it difficult to focus on what ware going to think about.
According to Katagiri, Student’s Mathematical Thinking divided into three things. They are attitude, method, and content. Attitude needs to be combined with some method to create a good content. So, the three things above are related one to another.
Then nature of School Mathematic according to Ebutt and Straker (1995), there are pattern, problem solving, investigation, and communication. The instruments that have to be used when we do a research are observation, question, and questioner (the subject).
