Abstract

The paper establish a virtual three-dimensional experimental instrument model by virtual reality modeling language, and a programming language VB is used to design an interactive virtual experiment platform. Its operating interface is similar to the style of Windows. It has the characteristics of friendly interface, experimental phenomena and parameters Association. It is a revolution in the traditional teaching mode of physical experiment. Virtual experiment realizes the simulation of real experiment process, allowing students to operate experiments anywhere and at any time, and has practical use value.

Highlights

  • In recent years, with the development and deepening of modern education, some achievements have been made in the construction of teaching resources

  • In the teaching environment, there is a lack of Virtual Experimental Courseware closely related to the experiment, which affects the normal teaching of experimental courses

  • Some methods of experimental video are used in the teaching of experimental courses

Summary

Introduction

With the development and deepening of modern education, some achievements have been made in the construction of teaching resources. In the teaching environment, there is a lack of Virtual Experimental Courseware closely related to the experiment, which affects the normal teaching of experimental courses. Even in some teaching processes, there is a lack of experimental links, the quality of learning is difficult to be guaranteed, and it is impossible to cultivate skilled talents in accordance with the goal of training. For the students with experimental conditions, the school provided experimental equipment and teachers' field guidance, but before the experiment, the students did not have a full understanding the whole process of the experiment, the correct operation method, and the standardization of experiment and the effect of experiment. In order to leave the space for the students to explore, ensure the smooth progress of the experiment, to a certain extent, reduce the workload of experimental teachers, reduce the loss of experimental equipment and improve the quality of experimental teaching, and the virtual experiment of computer simulation is one of the ways to solve this problem
