Advanced mathematics teaching includes special curves such as cycloids. In the traditional mathematics teaching simulation, the teacher draws multiple circles on the blackboard with tools, and embodies the law of cycloids by finding points. The teaching efficiency and students' understanding are not very thorough. Some teachers show the pictures made after class during the teaching process. Although it solves the situation that there is no need to draw circles in class to a certain extent, the students' learning is not very intuitive and cannot be intuitive.

Abstract

The invention provides a cycloidal teaching aid for university mathematics, and belongs to the technical field of teaching equipment. The cycloidal teaching aid for the university mathematics is usedfor assisting in cycloidal teaching. Two glass plates are fixedly mounted at the left end and the right end of a swing frame in the front-back direction, a first track is arranged between the two glass plates and is fixedly mounted on the swing frame, a roller is mounted on the first track in a rolling manner, a rotating plate and the roller are concentrically fixed on a concentric shaft, a fixingring is arranged between the two glass plates, and is fixedly mounted on the swing frame, an outer round plate and an inner round plate are connected through a U-shaped rod, the two ends of the U-shaped rod are inserted in the inner side and the outer side of the fixing ring, thus, the outer round plate is tangential to the outer peripheral surface of the fixing ring, the inner round plate is tangential to the inner peripheral surface of the fixing ring, writing pens are detachably mounted on the outer round plate, the inner round plate, the rotating plate and the ball separately, and the four writing pens separately write on the corresponding glass plates. By the cycloidal teaching aid for the university mathematics, students can visually and effectively observe the travel of a cycloid,and the teaching effect is improved.

Description

technical field [0001] The invention belongs to the technical field of teaching equipment, in particular to a cycloid teaching aid for university mathematics. Background technique [0002] Cycloid is one of many fascinating curves in mathematics. It is defined as follows: a circle slowly rolls along a straight line, and the trajectory passed by a fixed point on the circle is called a cycloid. Advanced mathematics teaching includes special curves such as cycloids. In the traditional mathematics teaching simulation, the teacher draws multiple circles on the blackboard with tools, and embodies the law of cycloids by finding points. The teaching efficiency and students' understanding are not very thorough. Some teachers show the pictures made after class during the teaching process. Although it solves the situation that there is no need to draw circles in class to a certain extent, the students' learning is not very intuitive and cannot be intuitive. The observed travel of the ...
