Sand table simulation device for economic teaching

Abstract

The invention discloses a sand table simulation device for economy teaching. The device comprises a panel and a plurality of counting devices, wherein the panel is disposed on a table top and is provided with a plurality of installation holes; a plurality of counting devices are arranged, a plurality of counting devices are all mounted in the mounting holes of the panel, each counting device comprises a mounting rack mounted in the panel, a frame is arranged on one side of the mounting rack, a convex lens is arranged in the frame, a counting screen is arranged below the convex lens, the bottom of the counting screen is provided with a connecting disc, a surface of the connecting disc is provided with a label area, and a surface of the mounting rack is provided with buttons capable of increasing or decreasing numbers of the counting screen. According to the device, the convex lens is used, so the area of the sand table can be reduced, an inclination angle of a visual angle of a student is reduced, and the student can conveniently sit and observe; and secondly, M coins are replaced by the digital screen, so characters cannot be shielded, and the simulation of teachers and students is facilitated.

Description

technical field [0001] The invention relates to the technical field of economic teaching, in particular to a sand table simulation device for economic teaching. Background technique [0002] Economy is the creation, transformation and realization of value; human economic activities are activities that create, transform and realize value and meet human material and cultural needs. Economics is the study of the law of human economic activities, that is, the law of the creation, transformation, and realization of value. 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. [0003] The sand table simulation is an experimental...

Problems solved by technology

[0005] However, the traditional sand table has a large area. Since students sit and stand around the sand table, students observe the sand table cloth from an oblique angle of view. Some texts on the sand table cloth may not be clear and need to stand to watch. It is tiring and inconvenient for students to stand for a long time use by students;

[0006] Secondly, when M coins are placed on the table, they are stacked and vertical, which may cover part of the text, resulting in some students or teachers not being able to see the text in the corresponding area, which is inconvenient to simulate
