Research On Practical Work In Primary School Science

The development of science and technology puts forward new requirements for the scientific literacy of every citizen.The Primary School Science Curriculum Standard(2017)points out that the primary school science curriculum is a practical course.The development of the foundation,practice is the core word of primary science.At the same time,in July 2021,the General Office of the Central Committee of the Communist Party of China and the General Office of the State Council issued the "double reduction" policy,which clearly proposed to effectively improve the quality of homework and reduce the burden of students’ excessive homework.In this context,primary school science assignments also urgently need to be changed to meet the new requirements of the new era.Practical homework,as a new form of homework,not only has the general functions of consolidating and expanding curriculum knowledge,supervising and managing,but also can highlight the practicality and participation of primary school science lessons.This paper is mainly based on the subject nature of primary school science,and takes the current situation of primary school science practical work as the starting point of the research,and is a case study of investigation and improvement of primary school scientific practical work.First of all,the current situation of the primary school science practice homework was investigated,and the students in grades 3-6 of the primary school in the core area of F city were selected to conduct a questionnaire survey.At the same time,select primary school science textbook supporting exercises for text analysis,and collect scientific practical homework cases designed and implemented by front-line teachers for analysis.Based on the above research and analysis,to understand the current situation of the design,implementation and evaluation of scientific practical assignments in primary schools,and based on the analysis of curriculum standards,teaching material content and learning situation,I take the "Making Yogurt Contest" as a case to explore the design of practical assignments,and make The practice test was carried out in a class of P primary school in F city.The purpose is to explore the principles,implementation methods and evaluation strategies of primary school scientific practical work design through practical research,so as to improve the quality of primary school scientific practical work and enhance students’ interest in learning science.Provide reference for front-line science teachers to design and implement practical assignments.On the basis of survey research and practical research,this paper applies Constructivist learning theory,Dewey’s "learning by doing" theory,Multiple Intelligence theory and STEAM education concept,etc.,trying to summarize the design principles of primary school scientific practice homework mainly including:(1)homework The principle of goal setting,that is,the principle of suitable for student development,the principle of subject teaching objectives as the core,the principle of appropriate penetration of interdisciplinary goals and the principle of comprehensive quality improvement;(2)the principle of homework content design,that is,the principle of life,the principle of innovation,the principle of difference Sexuality and Interdisciplinary Principles.Try to summarize the implementation and operation strategies of primary school scientific practice homework:(1)clarify homework goals and requirements;(2)build study groups;(3)communicate and interact with teachers and students;(4)multiple types of results based on students’ practical homework design.Try to put forward the form of practical work evaluation:(1)focus on the principle of process evaluation;(2)diversification of evaluation subjects.
