With the constant development and progress of information technology,the level of development of education information is also rising.Under this background,there has been a computer-aided instruction system that is used in various disciplines to assist teaching or to provide an independent learning environment to help Students improve learning efficiency and learning quality.Including the practical operation of the strong chemical discipline.By analyzing the deficiency of the existing chemistry teaching aided system,this paper improves and innovates it,and redesigns and realizes a chemistry teaching aided system based on WebGL and augmented reality technology.In this paper,the concept of software engineering,first of all the needs of the system analysis,and then on the basis of the needs analysis of the system design and detailed design of the summary,and ultimately the teaching support system.Through the experiment and test of the system,the practicality and innovation of the system are verified.The chemistry teaching aids system implemented in this paper provides an independent learning environment for students and provides assistance for teachers’ teaching.This system abandons the previous C/S architecture and uses the B/S architecture instead.The system uses WebGL 3D technology to make the functional modules three-dimensional,and also uses augmented reality to make innovations in the system’s learning and interaction.System includes user management,periodic table learning,molecular club model platform,virtual laboratory four subsystems.User management subsystem supports different roles users in the system to register,log in,and modify personal information and other operations;the use of augmented reality technology,the periodic table sub-system in the mobile terminal page to achieve a combination of actual situation and interactive learning so that users can The virtual element atomic structure is observed under the real world picture.The molecular stick model operating platform provides an online stick model editor for chemistry teachers,supports the functions of uploading,importing,exporting and editing models,and also provides students with browsing,View the capabilities of the Molecule Stick Model;virtual labs utilize WebGL and related page 3D technologies to implement a three-dimensional lab scenario that allows users to navigate around scenes and interact with chemical instrument models in the scene through the mouse and keyboard.The teaching aid system can help students to shorten the time of secondary school chemistry,improve their interest in learning chemistry in middle school and stimulate their creativity.At the same time,they can bring practical teaching aids to teachers.It is a teaching aid system with important practical application value. |
