A teaching tool for advanced mathematics

Abstract

The invention provides a higher mathematic teaching aid. The higher mathematic teaching aid comprises a mounting frame, a movable board, a driving assembly, a sliding sleeve, a light emitting board and a light emitting board control device, wherein the mounting frame comprises a writing board, pen clips, board erasing frames, support legs, air holes, a motor mounting lug, sliding sleeve mounting grooves and a movable board mounting frame. The higher mathematic teaching aid has the advantages of simple structure and convenience in use, is capable of presenting prepared electronic courseware and coordinate graphics to students via the light emitting board, reducing the trouble of drawing the coordinate graphics by a teacher on site and improving proportion precision of the coordinate graphics; the writing board can also be used independently; different using effects can be achieved by adjusting the distance between the light emitting board and the writing board, so that the teaching efficiency can be improved.

Description

Technical field [0001] The invention relates to teaching aids, in particular to an advanced mathematics teaching aid. Background technique [0002] As a basic subject, advanced mathematics is a compulsory course for students, due to its abstract thinking, close formula relations, and complex calculation formulas. In teaching, teachers usually write long calculations on the blackboard, and the teacher writes the calculations next to the calculations when explaining the calculations. Students are easily confused when watching and taking notes. In order to help teachers explain, they usually draw Some coordinate axes, graphics, and curves are expressed. Since there are no coordinate lines on the existing blackboard, teachers can only draw by hand on the spot, and the drawn graphics have large errors, which leads to inaccurate function curves and reduces teaching efficiency. The existing public patent "A teaching aid for advanced mathematics teaching" patent number 201521124361.3, ...

AI Technical Summary

Problems solved by technology

Because there are no coordinate lines on the existing blackboard, teachers can only draw manually on the spot, and there are large errors in the drawn graphics, resulting in inaccurate function curves and reducing teaching efficiency

The existing published patent "a teaching aid for advanced mathematics teaching" patent number 201521124361.3, although a coordinate board is installed on the writing board to facilitate the drawing of coordinates and graphics, and the installation position of the coordinate board can be adjusted according to the requirements of use, but in use However, teachers still need to draw graphics on the spot, which wastes a lot of time in the drawing process, and the coordinate grid on the coordinate board makes the coordinates become complicated, the visual effect is poor, and the teaching efficiency is reduced
