The Development And Application Research Of High School Biology Physical Model Based On 3D Printing Pen

As a more effective teaching method,the teaching of biological physics model has been loved by teachers and students.With the implementation of the new curriculum reform,the new curriculum standard requires students to have a certain modeling ability.Under the impetus of the rapid development of emerging science and technology,the development,design and innovation of the physics model of biology teaching is also an important embodiment of the implementation of the reform.By retrieving the literature on the physical model of high school biology in the Knowledge network,found that most of this research is in the theoretical research stage,and the domestic system of biological physics model teaching is not perfect.The purpose of this paper is to develop high school biological physics model resources by using 3D printing pen technology,and to apply it in teaching practice,and to provide new ideas for the development and production of biological physics model resources in senior high school through the combination of theory and practice.This paper uses the literature research method to search and consult the literature on the Teaching of biology physics model in senior high school in China,and through a large number of readings and comments,the concept,classification,physical model selection and construction process of the model are summarized,and the concept of 3D physical model and 3D printing pen is defined;a total of 7 sets of teaching models of 3D physics model and 3 cases of teaching design and activity design are developed by using the method of practical research,and the 3D physical model developed by experimental research method is applied to classroom teaching practice,and the teaching model developed by behavioral observation method can obtain better teaching results;the results of this study are explained by summing up and reflecting the method,and the conclusion is finally drawn.Based on the theory,after elucidating the purpose,significance,content,object,method,idea and innovation point of the research,this paper summarizes the selection basis of constructing the physical model by using 3D pr:inting pen:according to the important concept in the curriculum standard,according to the difficulties of students'understanding,according to the characteristics of 3D printing pen,the design principle of 3D physical model:The principle of reductionism,the principle of practicality,the principle of simplification,the principle of artistry,the general production process of constructing physical model by using 3D printing pen:determining the object,the characteristics of the research object,selecting materials,making plans and design drawings,preparing materials,making models according to design,testing and optimization,display and communication.Based on this,the author develops 3D physical model,prepares teaching and activity design,and applies the developed high school biological physics model to the classroom,summarizes the effect of this study,draws conclusions,reflects,summarizes the advantages,and puts forward the shortcomings of the research through the comparison between the experimental class and the behavior of the students in the control classes.The results of teaching practice show that the 3D physical model developed in this study is applied to teaching,the students'attention is attracted,the learning interest is improved,the students'speaking situation is improved,the learning effect is improved,the students'independent learning situation is strengthened,the active learning is carried out,the students'homework completion level is improved,the knowledge mastery is more accurate,the quality of teachers ' preparation at relevant knowledge points has also been improved,which broadens the selectivity of teachers to the teaching of biological physics models.The above research proves that the physical model developed in this study is helpful to the teaching of biology in senior high school.This study provides limited resources and ideas for the development and production of biological physics models in senior high schools,and hopes to be helpful to the majority of teachers and students in relevant aspects.
