Design And Development Of Chemistry Virtual Experiment System Based On Embodied Cognition Theory

With the rapid development of educational informatization,virtual experiment has become an effective means of experimental teaching.Virtual experiments can not only break the limitation of time and space,but also avoid the safety problems in real experiments.In order to make the virtual experiment bring more teaching benefits into play and better meet the requirements of experimental teaching,this thesis applies the embodied cognition theory to the design and development of virtual experiment.In recent years,embodied cognition theory,as an important research field of cognitive psychology,has been widely concerned by more and more scholars.It emphasizes that the human body is inseparable from the occurrence of cognition,and based on the specific body structure and physical activities in the environment,it is the result of the joint action of body,environment and activities.Pedagogy and psychology continue to pay attention to the occurrence of cognitive process and the improvement of learning efficiency.Based on this,from the perspective of embodied cognition theory and relying on virtual reality technology,the design and development of chemical virtual experiment system based on embodied cognition theory are studied in this thesis.(1)This thesis firstly analyzes the domestic and international status of the research,and defines the key theories and concepts,by combing the theories of embodied cognition and learning-based instructional design,the author puts forward the necessary elements for the occurrence of embodied cognition,and puts them into the design elements of virtual experimental system,so as to form the guidance of theory to practice.(2)This thesis summarizes the design principle of virtual experiment and proposes the design process and systematic learning mode of virtual experiment system of high school chemistry based on embodied cognition theory.In this study,students in the second year of senior high school were selected as experimental subjects and chemistry experiment as learning content,using Unity3 D,3ds max and other software to develop a chemistry virtual experiment system based on embodied cognition theory,students can make use of the system to carry out specific operation training.(3)Finally,the system has been modified,improved and put into use,andthrough the experiment and the form of questionnaire survey to use the effect of feedback and summary.After the actual use of the system,the data show that the research and development of the virtual experiment system has a positive effect on students’ chemical experiment learning,and it can be seen that the design process of the chemical virtual experiment system based on embodied cognition theory proposed in this thesis has a good practical significance.The research combines theory with practice,and on the basis of theoretical analysis and pattern design,it introduces and explains the design and development process and results of practical cases,conducts experiments and analyzes data.The study provides theoretical and practical references for the educational application of embodied cognition and virtual reality.
