| The "Physics Curriculum Standards for Ordinary High Schools(2017 Edition,2020 Revision)" proposes the core competencies of the physics discipline,which include forming basic physics concepts,mastering scientific exploration methods,forming good scientific thinking,and cultivating correct scientific attitudes in the classroom.How to effectively implement the above requirements in practical teaching is one of the urgent problems to be solved in frontline teaching.Conducting experimental teaching with 3D printed high school physics self-made teaching aids can effectively respond to the above issues to a certain extent.This article will use literature review,questionnaire survey,and case study methods to study the development of 3D printing teaching aids,the practice of 3D printing teaching aids in teaching,and the evaluation of the teaching effectiveness of 3D printing teaching aids.Firstly,this article takes the self-made 3D printing teaching aid "elevator model" as an example to introduce the selection of software and printing methods in the process of making 3D printing teaching aids,as well as detailed operating steps.This can provide a certain reference for teachers who want to participate in the production of 3D printing teaching aids.Firstly,using 3D model design software or 3D scanner to design a 3D model,it is necessary to consider the size,shape,details,etc.of the model to ensure that it can meet the requirements of 3D printing.Next is the selection of 3D printing methods.Commonly used methods include melt deposition 3D printing and photocuring printing.These two methods have their own advantages and disadvantages in terms of cost,stability,printing speed,and can be selected based on actual application environments.After the 3D model is printed,it needs to become a teaching aid that can be used in the classroom,and further processing,including model trimming and assembly,and integration with other instruments,is required.Secondly,combining the 3D printing teaching aid "elevator model" to conduct classroom practice research on "overweight and weightlessness",using examples to help readers solve the confusion of how to integrate 3D printing teaching aids into teaching.Overweight and weightlessness "is the content of the sixth section of the fourth chapter" The Relationship between Motion and Force "of the new curriculum standard for high school physics in the People’s Education Press.This section can further consolidate students’ knowledge of force analysis and Newton’s laws of motion.The elevator model has appeared in both the old textbooks of the People’s Education Press and the new textbooks of the 2019 edition.Students have a strong interest in phenomena related to physics in daily life,but their understanding of the phenomena is not comprehensive enough and they lack deep rational thinking.So in the teaching process,3D printing of elevator models combined with acceleration sensors and pressure sensors is used to display elevator experimental data,and the intuitive nature of experimental teaching is used to reduce the difficulty of students’ learning.Thirdly,a comprehensive evaluation was conducted on the feasibility and practicality of 3D printing teaching aids.After completing the teaching practice of "overweight and weightlessness",this study first conducted a series of surveys on the "elevator model" of high school physics teaching aids based on 3D printing technology.The survey surveyed teachers’ opinions on self-made teaching aids at different stages and evaluated the effectiveness of 3D printing teaching aids after attending classes.The self-made teaching aid "elevator model" using 3D printing technology has solved the difficulties in designing and producing self-made teaching aids that arise in the production of traditional teaching aids,and the teaching effect is obvious in expanding new teaching modes.Finally,there is an evaluation of students’ learning outcomes,set up two student reference groups and two question groups to verify the learning effect of using 3D printing teaching aids such as "elevator models" by examining students’ analysis of the complete movement process,as well as the scientific inquiry methods in physics core literacy using sensors as carriers,and the ability of scientific inquiry thinking.After this study on the development and practical effects of high school physics teaching aids based on 3D printing technology,it has been found that teaching aids made using 3D printing have the following advantages: at the level of teaching aid production,3D printing reduces the impact caused by personalized customization.At the level of teaching aid application,when studying differentiated teaching modes,3D printing can enable teachers to achieve personalized creation of teaching aids from their imagination in today’s homogenized teaching mode,And by meeting different needs in the teaching process,3D printing maximizes the transformation of teachers from educational consumers to creators in teaching aids.Finally,corresponding teaching suggestions and research prospects are provided.Compared to other technology supported education(such as online education),the design of a creative learning environment supported by 3D printing is still in its growth stage and lacks learning resources that fully reflect the uniqueness of 3D printing.In short,3D printing provides new resources,tools,environments,and platforms for a brand new learning experience.Teachers can combine 3D printing teaching aids with "big unit teaching" to reflect the core competencies of physics,integrate across disciplines,and expand the formation of new learning styles. |
