The Application Research Of 3D Printing Technology In High School Biological Teaching

Nowadays,with the economic globalization and integration,the competition among countries can be attributed to the competition of comprehensive national strength,especially in terms of the competition of talents.Therefore,the strategy of strengthening the country with talents has been implemented in all countries.As a way to achieve educational goals,the continuous innovation of curriculum is of great significance to realize the strategy of talent power.In the “Biology Curriculum Standards for General Senior High Schools(2017 version)” issued by the Ministry of Education in 2018.It is proposed to pay attention to the cultivation of students' core qualities,so that students can master the basic biological knowledge necessary for later study or life,as well as excellent innovative spirit and practical ability.Obviously,the traditional teaching methods cannot meet the standards and requirements of talent training in the new era.Therefore,continuously innovative concepts and technologies are needed to bring about progress in teaching methods.With the application of 3D technology in the teaching field,it plays a unique role in training students' practical ability and innovative thinking.Therefore,it is of great significance to study how to apply 3D printing technology to the biological teaching in high school in order to realize the requirements for talent training in the new curriculum standard and guide the teaching practice.This study comprehensively expounded the current development of 3D printing technology at home and abroad through literature analysis.Based on 3D printing technology research results and practices at home and abroad,the application value of 3D printing technology in high school biological teaching was analyzed in detail.Besides,through the design of two teaching cases "synaptic structure" teaching case and "specific immune regulation" to explain how to apply 3D printing technology to daily in biological teaching.Using pedagogical research methods to study the role of biology teaching activities that base on 3D printing technology in cultivating students' innovative ability and interest in biology,the academic performance in two classes(1st and 7th)with similar basic conditions in the second grade of a middle school in Wuhu City were chosen as experimental subjects for teaching practice;For the experimental class(class 1),the strategy of biological teaching based on the 3D printing technology was implemented,while for the control class(class 7),the teaching method based on 3D printing technology was not adopted.After the completion of half-semester teaching experiment,the control group used their spare time to supplement the relevant content.At the end of the half semester,The Williams Creativity scale(excerpt)and the Questionnaire Middle School Students on Biology Learning Interests were used as evaluation methods to test students' creativity and interest in biology,and data were collected and collated.The results showed that:(1)Compared with the control class,the experimental class had significantly higher interest in biology than the control class(p<0.01);(2)The innovation ability of students in the experimental class was significantly higher than that of the control class(p<0.01).Therefore,the research conclusion of this thesis was drawn: applying 3D printing technology in biological teaching modeling can not only improve students' learning attitudes,but also enhance their innovative ability.According to the research,there were still some problems in using 3D printing technology for teaching in middle schools.For example,insufficient attention to 3D printing technology,lack of course resources and teachers related to 3D printing technology,etc.Therefore,this article put forward suggestions from three aspects: Firstly,education management department,teaching unit,and front-line teachers.The education management departments should issue more detailed bills and documents and meanwhile establish a more diversified teaching evaluation system to promote the development of 3D printing technology in teaching;Secondly,schools need to increase the investment in 3D printing equipment and develop school-based courses in accordance with their own development status;Thirdly,teachers should pay attention to the role of 3D printing technology in teaching,study 3D printing technology seriously,and design 3D printing teaching activities carefully.And organize classroom discipline,and make full use of every minute of the classroom.
