Description

Sand table supporting device used in economics teaching

technical field

The utility model belongs to the technical field of teaching aids, in particular to a sand table supporting device.

Background technique

In the teaching process of economics, in order to better show students the content to be taught, sand table simulation, as an experiential teaching method, combines theory and practice very well, so that teachers and students can participate together, It greatly improves the fun of learning, so that students will not feel boring in the learning process, and greatly stimulates students' interest in learning. The bases of traditional sand table teaching aids are generally fixed and cannot be rotated, and cannot be raised and lowered by themselves, which is not conducive to the teaching of teachers and the viewing of students, seriously affecting the teaching effect, and some sand tables are too large. When placing demonstration modules, students need to Or the teacher stood up and caused some inconvenience to the teacher and students.
