Application Research Of Virtual Simulation Technology In Animal Experiment

With the rapid development of computer graphics technology and VR(virtual reality)technology,virtual simulation technology is more mature and perfect in teaching experiments.In vocational education,the education and teaching reforms are continuously deepened,and students' higher requirements for experimental hands-on ability and comprehensive quality are put forward.Most of the traditional experimental teaching uses pictures,video and multimedia courseware as the main teaching methods,supplemented by the display of specimens,the interaction ability is not strong,and students' interest in learning is not high.Especially in the animal experiment course of secondary vocational schools,students should purchase a large number of living animals for anatomy during anatomical animal experiments.The cost of experimental teaching is very high,and often subject to experimental environmental conditions,experimental equipment,safety and repeatability,etc.The extensive application of animal experiment teaching in secondary vocational teaching has seriously affected the quality of teaching.The use of virtual simulation technology in teaching experiments provides students with a vivid and realistic three-dimensional simulation teaching environment,which greatly reduces the cost of teaching experiments,and students are not restricted by time and space,and can share experimental teaching resources online.It has opened up a new teaching mode for animal experiment teaching in secondary vocational schools.This paper takes the animal experiment teaching course of secondary vocational school as the research background,taking the anatomy of sheep as an example,after systematically analyzing the professional characteristics of the secondary vocational teaching and the characteristics of the teaching experimental object,the 3D modeling software popular in the society nowadays The virtual simulation platform was compared and analyzed.Combined with the characteristics of the experimental teaching of secondary vocational school,the development of virtual experimental teaching system with Virss as the development platform was proposed with 3ds Max as the modeling technology,and the teaching environment equipment faced by traditional experimental teaching was solved.Insufficient,lack of funds for teaching experiments,lack of experimental hands-on ability,poor interaction,etc.,improve teaching quality and learning efficiency.The main contributions and innovations of this paper are:(1)Innovation in research methods.This paper uses the now popular VR(virtual simulation)technology to experiment teaching,which opens up a brand-new teaching mode for teaching,especially for secondary vocational experimental teaching.(2)Innovation in research perspectives.The traditional virtual experiment teaching is mainly used in electromechanical processing and anatomical medicine,but the virtual simulation teaching in the middle school animal husbandry is basically blank.This paper verifies the virtual simulation from a new research perspective.The feasibility of teaching in the experimental teaching of secondary vocational animals.(3)Innovation in research content.In the animal anatomy experiment,in order to reduce the teaching cost,the traditional experimental subjects are mainly small animals such as chickens,rabbits,frogs,etc.,lack of experiments on large animals such as cattle,sheep,etc.The study of this paper uses sheep as an anatomical object.Make up for this shortcoming.(4)Innovation in learning methods.In the current virtual simulation teaching experiment,most of the learning software is stand-alone version and paid for use.This teaching experiment system is an open and free learning system based on WEB format,which greatly improves the sharing and popularization of teaching experiment resources.
