Special electronic clock suitable for timekeeping when teacher gives lesson

Abstract

A special electronic clock suitable for timekeeping when a teacher gives a lesson. The electronic clock is characterized in that a clock face is divided into a class time period and an after-class time period, that a class time pointer rotates by 30 degrees represents five minutes, timekeeping of each lesson fixedly starts from a zero moment line at a right upper side position, a display screen which precisely displays remaining time from finish of the lesson is connected with the clock face with a turning pointer, and the remaining time display screen, a timekeeping pointer and clock face scales form a direct-reading type special timekeeping device for lesson giving. The electronic clock can perform speech recognition according to fixed class-starting and finishing bells of a school, and automatically keeps synchronous with the bell of the school, so that a teacher can rapidly and conveniently read time of a lesson that is given and time from finish of the lesson at a glance in class, neither needs to recall when the lesson is started, nor needs to calculate the remaining time of the lesson silently in mind, thus the teacher can conveniently and rapidly control a time proportion of each link of the lesson, thereby ensuring completion of teaching tasks of the lesson.

Description

technical field [0001] The invention relates to an electronic clock, in particular to a special time-keeping electronic clock which is convenient for teachers to grasp the teaching process during class. Background technique [0002] Usually, the clocks hung in the classroom are ordinary household or office electronic clocks, and generally do not have the function of visually displaying the time used or the remaining time of the teaching process. The time needs to be precisely controlled. For example, if an ordinary electronic clock is used, it must be calculated by the observer. Usually, the current time is subtracted from the start time of the class to know the elapsed time of the class. Then use a class The remaining time can only be obtained by subtracting the elapsed time from the total time. If the observation calculation is wrong or the time is not grasped properly, the knowledge points will be taught too quickly or the class will be delayed and the teaching goal will ...

Then use a class The remaining time can only be obtained by subtracting the elapsed time from the total time. If the observation calculation is wrong or the time is improperly grasped, the knowledge points will be taught too quickly or the class will be delayed and the teaching goal will not be completed.
