The Design And Practice Of Project-based Science Learning In Primary School With Big Ideas

Since the end of the 20th century,the concept and practice of global science education have undergone profound changes.The teaching of scientific concept is the focus of attention in science education,among which the science teaching around "big ideas" is one of the most popular problems.And project-based learning is a special form of scientific inquiry,with a comprehensive,challenging and interesting,able to cultivate students to use the scientific knowledge to solve real problems in the real world.In this paper,use the project-based teaching model change the traditional science class with big ideas,to solve the students in the traditional science class to learn the concept is too fragmented,unable to build the big ideas.In this paper,the concept of the concept of the use of the project-based teaching model to transform the traditional science classroom,to solve the students in the traditional science classroom to learn the concept is too fragmented,unable to build the concept of the problem.The paper analyzes the problems that the students can not construct the big concept in the traditional science classroom,and puts forward the project-based learning as the solution.By studying the key combination of concept and project-based learning,we can create a practical and efficient primary school science teaching model.This paper constructs a localized project-based primary school science teaching model.Through the study of project-based learning,according to the concept of big concept and the teaching practice of primary school science,the teaching model of project-based learning is carried out according to teachers' Students' autonomous learning ability and other primary school science teaching localization,so that it can really use in the practical teaching of primary school science,put forward to the concept,skills,technology,production,display,expand the six links to build the project-based learning Teaching model.Starting from the teaching practice,the author studies the localization of the project-based learning in the elementary school science curriculum,reconstructs and transforms the chapter "movement and force" of the fifth grade of the science science,and observes the effect of the classroom,To achieve the effect of transformation.This paper presents a new teaching model,although not perfect but also achieved some teaching effectiveness.Perhaps one of the possible innovations is to sort out the concept and the project-based learning theory.The second is to propose a process of project-based learning suitable for primary school science.Third,we design a typical case of "movement and force".This study may have some contribution to the teaching of primary school science,but there are still some problems in the practice process.For example,the idea of the concept can not be fully reflected in the teaching design.In the process of teaching,there is not enough space for students to learn,Evaluation mechanism has yet to be further improved.
