The Study On The Application Of 3D Printing Technology In Junior High School Science Teaching

With the deepening of basic educational reform,the goal of curriculum reform has been shifted to the cultivation of "students' key competencies".In recent years,3D printing technology is being developed rapidly,and more and more education researchers are paying attention to it.Then how to apply 3D printing technology to teaching practice,and how to take its advantages to improve teaching effects became a research hotspot.On the basis of ·summarizing the application of 3D printing technology,combining with the training objectives and discipline characteristics,two application modes of 3D printing technology in teaching are mainly studied,and conducts teaching practice.The methods such as literature research,questionnaire survey and action research have been used.Firstly,through literature research,the application status of 3D printing technology in education are analyzed,and the theories of 3D printing technology in teaching application are sorted out.Secondly,the application of 3D printing technology in some primary and secondary schools in Zhejiang Province was investigated.The questionnaire includes teaching objectives,teaching practice,teaching evaluation and feedback.It is found that teachers are generally optimistic about the application of 3D printing technology in teaching.But cause of the teachers' strength and equipment conditions,the form of using 3D printing technology in teaching process is relatively limited,and the application scope is not wide enough.Thirdly,combining with the characteristics of 3D printing technology and standards of the science curriculum,two application modes of 3D printing technology in science curriculum teaching are explored,and the advantages of these two application modes are analyzed.Finally,according to the actual situation of students and the junior high school science curriculum standards,two feasible teaching cases for above modes have been designed,and one case has been carried out teaching practice.The analyzing results show that the application of 3D printing technology in science teaching is beneficial to improving students' learning enthusiasm,group cooperation ability,and practical ability,and further to improving teaching effects.
