Abstract

The present invention provides a gear type random student number roll calling system for English classes belonging to the technical field of teaching auxiliary equipment, and aims to solve the problem that an English teacher can not fairly ask students of the whole class randomly in the prior art. The gear type random student number roll calling system for English classes includes a motor, a driving gear, a driven gear, light sources, glass panes and a plane mirror. The diameter of the driving gear is different from the diameter of the driven gear, the driving gear engages with the driven gear, the circumferences of the driving gear and the driven gear are each provided with ten through holes, one of the glass panes is arranged in one of the through holes, the glass panes in the ten through holes of the driving gear and the driven gear are each provided with one number of 0-9 orderly, and the two light sources are each corresponding to any through hole of the driving gear and any through hole of the driven gear. The driver drives the motor so as to drive the driving gear to operate or stop, a control system controls the light sources to emit light beams, the light beams emitted by the two light sources irradiate on the glass panel in the corresponding through hole, and the number on the irradiated glass panel reflects through the plane 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. Over time, it will cause some students to lose concentration in English class, which will lead to a decline in academic performance. 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...
