Research On The Development And Application Of Virtual Experiment System In Higher Vocational Colleges Based On Unity 3D

In the modern time,the Internet is connects to the world and technology is developing rapidly.Virtual reality technology has gradually entered into the field of vision,providing entertainment,learning and work experience to the society,schools,families and individuals.The rise of technology has brought new opportunities for higher vocational education,and the government supports the development of vocational education in many aspects of policy.And the application of new technologies,such as virtual reality and artificial intelligence,in education and teaching is constantly promoted in the informationlized educational environment.This provides a guarantee for the higher vocational colleges to carry out the teaching reform and to train the quasi professional people of the social needs.With the increasing application of virtual reality technology in education field,people began to realize its value.Some universities and academic institutions began to use virtual experiments to supplement their experimental training teaching.Virtual experiment is a new form of experiment based on virtual reality technology.By simulating the operation steps of traditional experiments,learners can perform experimental tasks just like in real environment,which enhances their practical ability.And higher vocational education is a kind of employment ability education oriented to professional and post activities.It pays more attention to the practical education of technologies and skills.Therefore,the virtual experiment system is used to carry out experimental teaching.To a certain extent,it can improve the impact of the shortage of field,equipment and funds in higher vocational colleges,so as to ensure the teaching effect.This study found that there are some problems in computer networking experiment courses in some vocational colleges,such as lack of equipment and lack of learning,which seriously affects students' learning enthusiasm and learning effectiveness.Therefore,the author planned to design and develop a virtual experiment system for higher vocational colleges,and improve the experimental course on the computer network.The specific research ideas are as follows:This study first combed and analyzed the related literature research and the actual situation of the virtual experiment system,and understood the advantages and disadvantages of the current virtual experiment system,so as to provide reference for this research.Secondly,the main ideas of the theoretical basis of the study were combed,and the connection between these theories and virtual experiments was analyzed.At the same time,the key technologies needed for system development are also introduced,which provided theoretical guidance for the design and development of the system.Thirdly,according to the questionnaire,the demand analysis was carried out,and the system architecture and functional modules were designed to provide a clear idea for the development of the system.Then,according to the design plan,the author selected the appropriate development tools:Unity3D and 3Dmax,expanded the development of the virtual experiment system,realize the various functional modules,and took the LAN construction experiment as a case,detailed described the implementation process of the experiment.Finally,in order to the effectiveness and acceptance inspection system,the researcher designed control experiment,collected the datum about the interest of learning,participation,learning satisfaction,knowledge and skills,to prove the soundness of the system.And the experimental group filled up a questionnaire to verify system acceptance.The conclusions of this study are:The use of the virtual experiment system can improve the interest of the students in the experimental study of Higher Vocational College;As the teaching effects,there is no significant difference in learning participation,learning satisfaction and knowledge skills between using virtual experiment system and real experimental teaching,which means virtual experiment system that can provide effective learning experience for higher vocational colleges lack real experiment conditions;In terms of system acceptance,through the investigation of system perceived ease of use,perceived usefulness and perceived satisfaction,the results show that the three means are relatively high,which proves that students can better accept the system and use the system to learn.
