Problems solved by technology

Now when teachers teach advanced mathematics, they don’t have any teaching aids. They can only use words and language to explain on the blackboard. The concept of limit and probability is a very abstract concept, and it is the foundation of college mathematics. It is very difficult to explain it in this way. It is difficult for students to quickly understand, especially for the cycloid in advanced mathematics. Due to the complicated shape of the cycloid, it is difficult to achieve intuitive and profound effects if it is limited to book teaching, and cannot meet the teaching needs

Abstract

The invention discloses a multifunctional auxiliary device for mathematics teaching. The multifunctional auxiliary device comprises a base. Multiple universal wheels are arranged at the bottom end ofthe base. A supporting rod is fixedly arranged at the center position of the top end of the base. The top end of the supporting rod is rotationally connected with a supporting frame. Two protruding blocks are symmetrically and fixedly arranged on the side wall of the supporting rod and are in screw joint with bolts. The bolts penetrate the protruding blocks and are in screw joint with the bottom end of the supporting frame. Two positioning vertical rods are fixedly arranged on the inner opposite layers of the supporting frame, and a U-shaped demonstration plate A and a U-shaped demonstration plate B are arranged between the two positioning vertical rods. By means of the multifunctional auxiliary device for mathematics teaching, a demonstration plate body is divided into a front-face demonstration plate and a back-face demonstration plate, both double faces are applicable, limited space is reasonably utilized, in addition, the forming process of cycloids with different sizes can be visually displayed, and measuring is facilitated; in addition, a coordinate disc is arranged, drawing and teaching of various curves in mathematics teaching can be effectively ensured; and furthermore, arandom experimental device is arranged, multiple times of repeated operation are conducted, and therefore probability events can be demonstrated more visually.

Description

technical field [0001] The invention relates to the technical field of mathematics teaching, in particular to a multifunctional auxiliary device for mathematics teaching. Background technique [0002] Advanced Mathematics is a basic course for universities. Advanced Mathematics is a basic subject formed by combining simple calculus, probability theory and mathematical statistics, as well as in-depth algebra, geometry, and the intersection of them. It mainly includes calculus There are slight differences in various textbooks in other aspects. Now when teachers teach advanced mathematics, they don’t have any teaching aids. They can only use words and language to explain on the blackboard. The concept of limit and probability is a very abstract concept, and it is the foundation of college mathematics. It is very difficult to explain it in this way. It is difficult for students to quickly understand, especially for the cycloid in advanced mathematics. Due to the complicated sha...
