Display system for middle school mathematics teaching

Abstract

The invention relates to a display system for middle school mathematics teaching. The display system comprises a control module, wherein an upper part of the control module is provided with a liftinglever, a rotary power mechanism is provided on the upper right side of the lifting lever, a lower bearing module is provided on the left side, and the lower bearing module is connected with the rotarypower mechanism through the lifting lever. A vertical support column is arranged on the right side of the lower bearing module, and a left vertical adjustment module is arranged on the middle part. An upper bear module is arranged at that top of the vertical support column. A threaded connecting rod is arranged in the middle of the upper load-bearing module, and a load-bearing rod module is connected with the lower part of the threaded connecting rod. An upper adjustment module is arrange on that top of the bearing rod module, and a low adjustment module is arranged on the lower part of the bearing rod module; An intermediate adjustment module is arranged between the upper adjustment module and the lower adjustment module. The device of the invention is convenient to display the parabolain the process of mathematics teaching, and can display the opening direction of the parabola, adjust the opening size of the parabola, facilitate the display of the coordinates of different intersection points, and deepen the understanding of students on the parabola.

Description

technical field [0001] The invention relates to a display system for middle school mathematics teaching, which belongs to the technical field of mathematics teaching. Background technique [0002] At present, in the process of mathematics teaching, many parabolic functions are often encountered. These functions have some curves. The combination of numbers and shapes is also a major feature of high school mathematics. Many students are often not very familiar with function curves. It is impossible for students to accept this new method. Therefore, if students can be shown the real object, it will help students strengthen their understanding of the abstract concept of function, which needs to be improved. Contents of the invention [0003] The purpose of the present invention is to provide a display system for middle school mathematics teaching, so as to better demonstrate the teaching of parabolic function curves for students and improve students' understanding of the abstr...
