smartboard 11.4.In the teaching, in order to increase the interest of teaching, some teachers have added a lot of teaching materials related to the actual life of students, causing students to indulge in life and dilute the original "mathematical taste". Although mathematics needs to be related to life, this is mainly based on the fact that our mathematics education emphasizes the disadvantage of discipline. However, many teachers are prone to deviations when they understand, as long as they create life-like in teaching. The situation is an ideal mathematics teaching, which combines mathematics and life. Some teachers even advocate "mathematical life". Mathematics comes from life, but it is higher than life. Mathematics teaching requires our teachers to transform the mathematics of academic form into the mathematics of educational form. This transformation does not mean that we must reduce the academic nature of mathematics or ignore the discipline of mathematics. Its purpose is to help students through the creation of life situations. It is found that mathematics is around us. There are many mathematical problems in our lives. We need to look at things around us with a mathematical perspective. The purpose of creating a situation is only to help students understand mathematics, not to reduce the requirements of students to learn mathematics. Therefore, before using the interactive whiteboard for teaching, you need to consider the characteristics of mathematics, consider whether the situation you created can help stimulate students' mathematical thinking, promote students' understanding of mathematics, and not just consider students' interests.
