Description

A Speed Controller for English Reading Teaching

technical field

The invention relates to a teaching tool, in particular to an English reading teaching speed controller.

Background technique

In all kinds of teaching, especially in the teaching of English extensive reading, it is necessary to control and cultivate students' English reading speed, and the given materials must be read within a certain period of time, so as to improve students' reading speed. But after the current projector hits an article on the screen, there is no way to control the reading speed of students. When reading an article, they will habitually read very slowly. At the end of the allotted time, they stay in the first few lines, or read only a few lines. Therefore, it is difficult to control the speed of students by using projectors to give materials to students, which affects the cultivation and teaching of fast reading.

Contents of the invention

The technical problem to be solved by the present invention is to provide a speed controller for English reading teaching, which solves the problem that it is difficult to control the speed of students when using projectors to give materials to students, which affects the teaching of fast reading training.

The technical scheme adopted by the present invention to solve the above technical problems is: an English reading teaching speed controller, including a bracket, a rotating screen arranged around the bracket, a motor providing power for the rotation of the rotating screen, and a remote control for controlling the moving speed of the rotating screen switch, the rotating screen rotates around the support under the drive of the motor, the rotating screen is a ring structure, including a reading screen and a speed control screen made of transparent materials, the middle part of the speed control screen is set It is a transparent reading tape, and the two ends are set as non-transparent cover strips.

The width of the rotary screen of the present invention is 7cm, the length of the reading screen and the speed control screen is 12cm, the length of the reading tape is 1cm, and the length of the cover strips at both ends is 5.5cm.

The remote control switch of the present invention is provided with four buttons of speed-adjustable switch, speed-up, deceleration and jog switch.

The beneficial effects of the present invention are: the present invention designs a speed controller for English reading teaching, which forces students to finish reading the specified reading volume within the specified time, and if they do not read at the specified speed, they will not be able to see other contents of the article , this is because the transparent part of the rotating screen of this device can only see through 1-2 lines of text content, and other parts are covered. With the scrolling of the rotating screen, the reading content can be displayed to students in turn, and the scrolling can be controlled by remote control to achieve the purpose of practicing students' reading speed; when the content on the screen is scrolled, the reading screen scrolls to the front, and students can read the article as a whole; the adjustable speed switch on the remote control switch can control the rotation of the screen. Increase the screen rotation speed, cooperate with the deceleration switch to reduce the screen rotation speed, use the jog switch, every time you jog, the screen moves one line.

Detailed ways

As shown in the figure, an English reading teaching speed controller includes a bracket 2, a rotating screen 3 arranged around the bracket 2, a motor 1 that provides power for the rotation of the rotating screen 3, and a remote control switch 4 that controls the moving speed of the rotating screen 3, The rotating screen 2 rotates around the support 2 under the drive of the motor 1. The rotating screen 3 is a ring structure, including a reading screen 301 made of transparent material and a speed control screen 302. The speed control screen The middle part of 302 is set as a transparent reading strip 5 , and the two ends are set as non-transparent cover strips 6 .

The width of rotating screen 3 is 7cm, and the length of reading screen 301 and speed control screen 302 is 12cm, and the length of reading tape 5 is 1cm, and the length of both ends cover strip 6 is 5.5cm.

The remote control switch 4 is provided with four buttons of speed-adjustable switch, speed-up, deceleration and jog switch.

The English reading teaching speed controller provided by the present invention is installed in front of the projector lens, and can select automatic playback or manual jog playback with remote control as required. During jog playback, the screen will move one line each time the jog switch is moved.

When the content on the screen is displayed completely, the screen rotates to the reading screen part, and the content of the full screen will be displayed for students to read again, which is convenient and easy to control.

The English reading teaching speed controller provided by the present invention can also flexibly control the width of the reading tape 5 as required, thereby adjusting the number of rows of each display content.
