Research On The Application Of Engineering Design Concept In Primary School Science Teaching

With the development of economy and society,the global demand for engineering talents is huge.In addition to engineering education in higher education,more and more countries have begun to focus on integrating engineering education into basic education and training engineering talents who can adapt to future development.In 2017,China began to incorporate engineering education into the primary school science curriculum in an independent form.It started late.As for how to carry out engineering education in the primary school science curriculum,it still exists in teaching design,classroom teaching,and teaching implementation.Many urgent problems need to be solved.With the rise of the trend of integrated education,the integration of science and engineering is considered to be the integration mode that best meets the needs of basic education in China.As the core engineering design of engineering,it can connect engineering with scientific concepts and scientific inquiry by virtue of its rigorous engineering design process.In this context,this article incorporates engineering design concepts into primary school science teaching design,draws on classic teaching design models in the education world,builds a "primary school science teaching design model based on engineering design concepts",and conducts teaching practices,completed as follows jobs:This article firstly puts forward the research problems of this article through the comprehensive analysis of domestic and foreign literatures and the study of science education related policies,on the problems existing in the integration of engineering education in science education in elementary school science and the society's emphasis on the improvement of engineering literacy.Then by studying the related concepts of engineering design,the core concepts of engineering design,the main mode of teaching design,combined with some problems in the current science teaching in elementary school and the integration strategy of engineering design and scientific inquiry,this paper designs the "primary science based on engineering design concept" Instructional design model.Finally,use this model for teaching experiments,and conduct questionnaire surveys on students before and after the experiment and interview teachers after the experiment to verify the actual teaching effect of the model.The experimental results show that the students achieve better teaching goals,and the instructors believe that the engineering goals of the engineering design are completed well,which improves the teaching effect.At the same time,the results of the questionnaire survey before and after the experiment show that 98% of the students think The learning efficiency has been improved,and the acceptance of knowledge and active participation in the classroom have been significantly improved;94% of students recognize this teaching method and hope to continue to use this teaching method;80.3%of students 'engineering design ability It has been improved,and the ability to integrate theory and practice has also been greatly improved.Combine teaching observations,questionnaire survey data and teacher interviews it can be known that the application of engineering design concepts to elementary school science teaching can first help teachers achieve teaching goals and improve teaching effects.Second,it can stimulate students 'interest in learning,classroom participation and sense of learning achievement,and improve students' learning effects.Third,it can compare significantly improved students' engineering accomplishment.
