At present, the outstanding problem in China's mathematics teaching only ignores the mastery of mathematical foundation, that is, the correct understanding of mathematical concepts. On the one hand, textbooks underestimate students' understanding ability, and in order to "reduce the burden", dilute or even avoid some basic concepts that are difficult to understand; On the other hand, the exam-oriented strategy of "sea tactics" makes teachers have insufficient time and energy to study how to make students deeply understand basic mathematical concepts. It is said that the burden is reduced, but in fact the pressure on teachers and students has increased.
Without "process" teaching, because of the lack of mathematical thinking method as a link, the relationship between concepts can not be understood, and it is difficult to establish the relationship between concepts, which leads to the lack of integrity of students' mathematical cognitive structure.
