From of my lectures, I found some of the importance of two critical issues in mathematics education, which are:

Essence of school mathematics

1. Mathematics is pattern

Mathematics is a pattern. So that students can apply in their dailly mater. Even in other sciences are also very useful.

2. Mathematics is communications

   Mathematics is one form of communication which is very useful. Mathematics can be a form of communication if each of the individuals who interact in a world the same, namely the world of mathematics.

3. Mathematics is investigation

   Mathematics is a form of discovery. Because the method of mathematics and science, can produce the forms in the discovery of new knowledge which is very influential in the development of the age.

4. Mathematics is problem solving

Mathematics is a form of problem. Especially in science, mathematics is needed to progress human civilization.Nature of student of math

The Nature of student in Mathematical education

1. Student needs motivation

   Students must always motivated because he still has the unstable nature. If not, students despair just because of the problems small problems.

2. Student is unique

   All students have different characteristics, therefore, unique students. So in the teeth, we must be wise to all students.

3. Student have a competence

   Individual students have competence in himself. So we must be able to manage their competency that could be useful as well as possible.

4. Student is contextually

   Students have relevance, hence we must understand the relevance of that, so that we can take advantage of the creativity to develop each student.
