AI Technical Summary

Technical Problem

Existing technologies struggle to intuitively demonstrate the dynamic changes and spatial relationships of vectors to students, especially the difficulty in understanding them in three-dimensional space.

Method used

A mathematical drawing ruler based on a spatial rectangular coordinate system was designed. By setting Z-bars, Y-bars, and X-bars and using the rotation of the bars and the connection of sliding grooves, the ruler can switch from a two-dimensional plane to a three-dimensional space. The ruler also uses spotlights to display the dynamic changes and positional relationships of vectors.

Benefits of technology

By using an intuitive approach, students can understand the concept of vectors in three-dimensional space, thus improving their spatial imagination and comprehension abilities.

Abstract

The utility model provides a space rectangular coordinate system drawing ruler for mathematics, and relates to the field of teaching aids, the space rectangular coordinate system drawing ruler for mathematics comprises a Z rod and a Y rod, the end points of the Z rod and the Y rod are mutually fixed and arranged at 90 degrees, the fixed point of the Z rod and the Y rod is rotatably connected with an X rod, and the plane formed by the rotation track of the X rod coincides with the symmetry plane of the Z rod and the Y rod. The three coplanar rods are arranged to assist in drawing a two-dimensional rectangular coordinate system on a plane blackboard or a drawing position, meanwhile, one straight rod is rotated to enable the three rods to form three shafts simulating the rectangular coordinate system, switching between a drawing ruler and a display teaching aid is completed in a simple rotation mode, and the teaching efficiency is improved. Students are helped to understand the essence of mathematical concepts such as vectors in a coordinate system through a visual display teaching aid.
