Instructional Design And Applied Research Of Physics Experiment Expansion Course Using 3D Printing Technology In Senior High School Based On PBL

The report "China's Education Modernization 2035" pointed out that my country should speed up the construction of education informatization.There are a lot of indoctrination teaching and lack of inquiry activities in the current traditional education methods.Aiming at these problems,this paper introduces project-based learning(PBL)into the construction of high school physics teaching activity model.PBL in informatization teaching mainly refers to the process of inquiry learning in the form of projects by using information technology,combined with the subject knowledge of the corresponding projects,through the teacher-assisted and student-oriented approach.Emphasizing "learning by doing",students' self-exploration of knowledge and self-solving of practical problems are the essential characteristics of PBL.The current high school physics curriculum focuses on cultivating students' basic cognition and inquiry ability of physics,but there are still some problems in teaching methods and teaching resources that need to be further solved.,the level of learning motivation is low.And PBL can just solve these problems.Based on relevant literature,this paper firstly expounds the development stage,basic structure and activity design of PBL,and summarizes experience through research and analysis at home and abroad;secondly,based on PBL,activity theory and tower of experience theory,combined with 3D printing technology,design and practice A 3D printing high school physics experiment expansion course teaching activity model based on PBL;based on this model,and fully considering the characteristics of high school learners and the content of high school physics teaching,ten teaching cases are designed.Finally,this research relies on the actual high school In the physics classroom scene,a teaching practice activity was carried out in a middle school in S City.This paper conducted a pre-test before the teaching practice activity;in the teaching activity,the learning process evaluation,project work evaluation,and project optimization evaluation were carried out,mainly through self-evaluation There are three evaluation methods: mutual evaluation with groups and teacher evaluation.After the teaching practice activities,this paper uses the interview method and the questionnaire survey method among the students who are taught to investigate the learning activities of the high school physics experiment expansion course based on 3D printing,and obtains the evaluation and questionnaire feedback data.Through the analysis methods of pre-test and post-test,the obtained data is scientifically analyzed.Through analysis,this paper finds that the 3D printing high school physics experiment expansion teaching activity design model based on PBL can effectively improve students' learning experience and interest in high school physics,and is conducive to cultivating students' innovative and creative thinking,and the ability to think logically and rigorously.,hands-on ability.Overall,the research in this paper has a positive effect on students' learning of high school physics courses.
