Description

A Calculus Mathematics Auxiliary Teaching Aid

technical field

The utility model relates to the technical field of teaching aids, in particular to an auxiliary teaching aid for calculus mathematics.

Background technique

Calculus is widely used in science, economics, and engineering to solve problems that cannot be effectively solved by algebra alone. Calculus builds on algebra, trigonometry, and analytic geometry. In the process of mathematics learning in the second year of high school, we began to know and get in touch with derivatives and definite integrals, but the learning and understanding of calculus is more difficult. For high school students, the study of calculus has always been difficult and important. For students and teachers, the fundamental reason why calculus is difficult to learn and teach is that the subject of calculus is relatively abstract, difficult to imagine, and even more difficult to intuitively understand. However, there are relatively few teaching aids in mathematics calculus teaching in senior high schools. Teachers can only draw various shapes and calculus schematic diagrams on the blackboard. This teaching method makes students feel boring, and it is very difficult to understand and master the principles of calculus. Therefore, the initial stage of calculus entry and learning has always been a difficult point for teachers and students. Teachers need to spend a lot of time drawing and demonstrating on the blackboard, and students also need to spend a lot of time to understand and master it.

At the current stage of calculus learning, the teaching efficiency is extremely low, students master it very slowly, and it is very difficult to learn. Therefore, there is a need for an auxiliary teaching aid for calculus mathematics that can more intuitively reflect the principles of calculus.
