Gear-style random point student number system for English classroom

Abstract

The gear-type random student number system used in English classrooms belongs to the technical field of teaching aids, and aims to solve the problem in the prior art that English teachers cannot randomly ask all students in the class fairly. The invention includes a motor, a driving gear, a driven gear, a light source, a glass plate and a plane mirror; the driving gear and the driven gear have different diameters, the driving gear and the driven gear mesh, and ten channels are evenly distributed on the circumference of the driving gear and the driven gear. There are glass sheets in the through holes, and the numbers 0-9 are written on the glass sheets in the ten through holes of the driving gear and the driven gear in turn. The two light sources are respectively connected to any through hole on the driving gear and the driven gear Any through hole on the gear corresponds to it; the drive motor drives the driving gear to run and stop, and the control system controls the light source to emit light beams. The light beams emitted by the two light sources shine on the glass plate in the corresponding through hole, and the glass is illuminated. The numbers on the board are reflected by a flat mirror.

Description

technical field

[0001] The invention belongs to the technical field of teaching auxiliary equipment, and in particular relates to a gear-type random number counting system for English classrooms. Background technique

[0002] In the current English class, English teachers usually randomly ask students questions, and the objects of the questions are often chosen subjectively by the English teachers. This has caused some students to be often forgotten by the English teachers and never get questions.

However, there is no corresponding teaching aid in the prior art to help English teachers to ask random questions to the whole class fairly. Contents of the invention

[0003] The purpose of the present invention is to propose a gear-type random student ID system for English classrooms, which solves the problem in the prior art that English teacher...
