Cycloid demonstration teaching tool for advanced mathematics teaching

Abstract

The invention discloses a cycloid demonstration teaching tool for advanced mathematics teaching. The cycloid demonstration teaching tool includes a blackboard. First and second gears on the front of the blackboard are sleeved with an endless chain. A drive motor is further disposed between the first gear and the second gear. An output shaft of the drive motor is equipped with a driving gear thereon. The driving gear and the second gear are engaged. A rack is disposed below the endless chain. Both ends of the rack are provided with limit blocks. A working gear is connected between and engaged separately with the ring chain and the rack. A support bar is disposed in the middle at the bottom of the blackboard. The lower end of the support bar is provided with a base plate seat. The bottom outer ring of the base plate seat is provided with a plurality of rollers. The support bar is also fitted with a sleeve thereon. The outer circumference of the sleeve is provided with a plurality of support legs. The cycloid demonstration teaching tool of the invention is simple to operate, time-saving and labor-saving, capable of allowing students to observe the cycloid intuitively, conducive to the students' understanding of the cycloid, easy in chalk replacement, high in stability and easy to move.

Description

Technical field [0001] The invention relates to a teaching aid, in particular to a cycloid demonstration teaching aid for advanced mathematics teaching. Background technique [0002] The cycloid is one of the many fascinating curves in mathematics. It is defined as follows: a circle rolls slowly along a straight line, and the trajectory of a fixed point on the circle is called the cycloid. Advanced mathematics teaching includes special curves such as cycloid. In traditional mathematics teaching simulation, the teacher draws multiple circles on the blackboard with tools, and finds points to reflect the law of cycloid, which has an invisible influence The teaching efficiency is not very well understood by students. Some teachers use pictures made after class to show during the course. Although to a certain extent, the situation of not needing to draw a circle in class is solved, but the students’ learning is not very intuitive and not intuitive. Observe the stroke of the cycloid. ...

Problems solved by technology

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 cycloid
