Research On Teaching Design Of Science Course In Primary School Based On "Integration Of Science And Engineering"

Under the influence of the rapid development of the concept of STEM education,science courses are the main channel for the implementation of STEM.It is very important to find new teaching design methods suitable for the scientific learning of primary school students in our country.In particular,the new curriculum standard proposes to transform "scientific inquiry" into "curriculum practice",and adds a "technical engineering field" section.After comparing the integration of "science-number" and "science-technology",it is found that the integration of science and engineering It is the beginning of problem solving and an effective way to consolidate the core knowledge of the subject and design and create.At the same time,the talents cultivated by "science-industry integration" are comprehensive,creative,and capable of accepting failure and reflection,which meet the requirements of training talents with scientific and engineering literacy.Therefore,it is particularly important to study the teaching design of the elementary science curriculum of "science-industry integration".This research takes "science-industry integration" as the research point,focuses on the teaching practice foundation of "science-industry integration",uses literature analysis,case analysis,theoretical research and other research methods to sort out scientific teaching design and engineering education in elementary schools.,"Science-industry integration" related literature,and through practical basic analysis,summarized effective teaching design strategies,and developed a "science-industry integration" elementary school science teaching case.This article first introduces the essence of "science-industry integration" starting from the connotation of science and scientific literacy,engineering and engineering literacy,and integration,and from this,it digs out that "science-industry integration" points to research results,highlights the design process,and the effectiveness of disciplines.Integration,emphasizing the combination of thinking and doing.Finally,it compares "subject-numerical integration" and "subject-technical integration" to discuss the advantages of "science-engineering integration" and its value to students and science courses.Secondly,on the basis of analyzing the essence of "science-industry integration",seek the theoretical basis for guiding instructional design.After analyzing the multiple orientations of scientific instructional design of "science-engineering integration",the author believes that the design orientation of scientific inquiry and engineering design should be selected,and the balanced development of the two should be effectively sought in the real situation.Under the guidance of elementary school science curriculum standards,multiple intelligence theory,constructivism theory,curriculum integration theory,connectionism theory and other theoretical foundations that incorporate STEM concepts,formulate overall related structural principles,result-oriented contextual principles,and teaching methods Teaching design principles such as flexible and diverse principles and multiple rating methods.In order to understand the current situation of the teaching design of "subject-industry integration" in the elementary science curriculum,we selected the appendix cases in the domestic elementary science curriculum standards,the collection of foreign outstanding science education cases,and the "subject-industry integration" cases in the open class on the website for analysis.After comparing and analyzing the design of each case according to the analysis framework of teaching objectives,process and method evaluation,summarize the design inspiration: the integration view of "environmental theory",the integration goal of scientific knowledge and engineering design,and the integration covering the complete engineering design process Content,focusing on the extension effect of teaching integration evaluation,to guide teaching design.After interpreting the connotation of "subject-industry integration",combing the theory of guiding instructional design,and analyzing the practical basis,the elementary school science teaching design strategy of "subject-industry integration" is proposed.The first is the design of teaching objectives that integrate engineering design and point to practical ability;the second is the design of project-based,modular teaching methods;the third is the design of the teaching process corresponding to science and engineering practice and engineering design;the fourth is to focus on the design process Teaching evaluation design combined with product output.Finally,based on the "science-industry integration" teaching design strategy summarized after theoretical and practical research,an activity is selected for teaching design.This article selects the "design and construction of waterproof earth dam" activity,and conducts courses and learners in accordance with the teaching design process Preliminary analysis,determination of teaching objectives,organization of the teaching process in accordance with the complete engineering design process,and finally evaluation of the teaching results through the design evaluation table.
