Innovation And Practice Of Elementary Science Teaching Aids-"Technology And Engineering"

Since the 21st century,the raging tide of curriculum reform had been prevailing throughout around the world.Both STEM education which originated in the United States and STS curriculum which originated in the Britain place great emphasis on the connections between different subjects.The Primary Science Curriculum Standard of Compulsory Education,2017 added the field of "material science" to the field of "technology and engineering".From this change,we can see that Chinese primary science education is paying more attention to the application and practice of knowledge like other countries does.The study in the field of "technology and engineering" is inseparable from the support of material materials.Well-designed teaching tools play a crucial role in cultivating students’ innovative consciousness and improving their ability to use knowledge.Therefore,it is necessary to innovate teaching aids in the field of "technology and engineering",enrich teaching resources in this field,and improve the teaching quality in the field of "technology and engineering" in the primary science stage.In the process of teaching practice,the writer discovers that the "technical and engineering fields of the existing teaching students to give the create space is insufficient,students lack of thinking in the process of engineering practice,cannot achieve the combination of hands and brain,it often makes the course into a handmade or labor skills classes,in the field of" technical and engineering "in the field of teaching are often unable to meet the requirements of curriculum standards.Therefore,this paper sorted out the education situation of " technology and engineering " field at home and abroad by referring to relevant literature,and deeply understood and analyzed the teaching situation of " technology and engineering " field and the innovation of teaching tools in this field by means of questionnaire survey and teacher interview.On the basis of the investigation,the author combined with a line of elementary school science teacher experience and guidance of the teacher’s education idea,innovative according to their own teaching experience,puts forward the primary school teaching in the field of science and technology and engineering " innovative process,and in jiangsu phoenix education publishing house in the elementary school science textbooks " a little wheel spin " this lesson teaching innovative as a case,This paper expounds the specific process and method of teaching aids innovation respectively,and makes a comparative analysis of the use effect of innovative teaching aids through the comparative experiment of two classes.Generally speaking,the application effect is relatively obvious.This study hopes to provide some reference for many science teachers in the innovation of teaching aids in the field of "technology and Engineering".At the same time,it also hopes that many excellent science teachers can establish the concept of lifelong learning,constantly understand the advanced ideas of international technology and engineering education,strive to constantly push through the old and bring forth the new in the innovation of teaching aids,and contribute more to China’s technology and engineering education.
