The professional quality of mathematics teachers can not be simply measured by how much mathematics knowledge they have learned. Mathematics professional quality can be divided into three aspects:

1. From the point of view of knowledge, we should master the basic mathematical knowledge of elementary mathematics and advanced mathematics well.

2. In terms of ability, there should be a strong ability to solve problems.

3. Ideologically speaking, we should have a correct attitude and philosophy towards mathematics, have enough understanding of the development history and thinking of mathematics, love mathematics and be able to keep learning and thinking.

Teachers with mathematical literacy

1. Teachers with solid knowledge base

2. Teachers who teach mathematics taste (thinking method and cultural taste)

3. Teachers who teach mathematics (mathematical spirit and humanistic spirit)
