Psychology of Teaching Learning Process of Mathematics
**Competence of teacher**
From elementary school until senior high school, I had various kind method of teaching learning process of mathematics. At elementary school, my teacher used approaching method as they used example of the object of mathematics. If we learn about triangle, they bought the example of triangle in order to their student know the shape of the triangle, not only imagine the shape of triangle.
In junior high school, I have smart mathematics teacher. His name is Mr.Karsono. His very easily if explanation about the problem of mathematics. He used explanation n exercise method. But, not only this method. He also used the other method because he think his student must bored if he used the same method in every time. I as his student very like it because I get new experience of his method in teaching learning mathematics. He give the student the fast formula of the problem solving. But before he give the formula, he always explanation how this formula come from. So, we not only get the formula but also know the process to get it. He always give the student homework in order to we always study mathematics in home and we habitual of mathematics not only in school but also in out of school.
When I was in senior high school, I had the unique teacher mathematics. She make teaching learning mathematics as playing games. Often the student to do a playing about topic in mathematics in front of class. She often used English to teaching mathematics in class. So we habitual listening and speaking in English in mathematics.
