Case Study On Development And Implementation Of Science Fun Experiment After Class For Primary School

In response to the new curriculum reform requirements,the "Primary Science Curriculum Standards" promulgated by the Ministry of Education in 2017 for the first time in the course content to join the field of technology and engineering,highlighting the importance and urgency of the new era for science education.In order to better cultivate students' scientific inquiry ability and improve their scientific literacy,it is necessary to extend the classroom experiment teaching from the classroom to the outside of the classroom.Therefore,this research is devoted to expanding the scientific experiment from the classroom to the after-school,developing specific post-class fun experiment cases,and conducting case studies.The thesis uses the discovery science inquiry teaching method,STEM education concept and PBL project-based learning as the theoretical basis,and uses literature research method,questionnaire survey method and qualitative analysis method to carry out research.Firstly,the research results related to the post-study fun experiment are collected,the research status at home and abroad is reviewed,and the concept definition of post-class fun experiment and experimental development is defined.Then,according to the research direction and the problems to be solved,the problem is established.The subject of this case study is all students in Grade A of Chongqing S Elementary School.Then,through the qualitative analysis of the characteristics of after-school fun experiments,the interesting experimental development principles and development strategies of this study are summarized.The textbooks and students' foundations are analyzed.On the other hand,the experimental content was established,and the students' thoughts were understood by questionnaires to better carry out the experiment.Then,according to the experimental contents of the textbook,the "air humidity meter" and "mini water purifier" were selected.Four experiments of shoebox guitar and artificial lungs,and completed these interesting experimental designs.Each experiment was designed with experimental and task lists to facilitate students to explore the fun experiment after class;weekly Students publish an experimental task that is required to be completed after class;after the experiment is completed,the class report and the form of the work are displayed.Exchange display;then through questionnaires and interviews with teachers and students to analyze the effectiveness of this case study.This study summarizes the development principles of the after-school fun experiment: the principle of interest,the principle of convenience,the principle of education,the principle of individuality,and the principle of relevance.And they have been successfully applied in four experimental cases.After the primary school science class,the fun experiment has a good effect and has reference significance.The case study confirms that the post-class fun experiment is highly feasible,and the summary of the overall development and implementation framework is available for reference.The thesis summarizes five principles for the fun experiment design and development after class: interesting principle,convenience principle,education principle,individualization principle and relevance principle,and gives the overall development design and implementation framework of the fun experiment after the science education.And applied in the design,development and implementation of the four experiments,and finally verified the implementation effect of the fun experiment after the primary school science class through questionnaires and interviews,and gave practical suggestions for the students' after-school science experiments.In order to improve students' scientific literacy,it provides effective and effective ways.At the same time,the thesis research also has positive reference for the development,design and implementation of post-class fun experiments for primary school science teachers.Through this case study,we have compiled a series of strategies and suggestions for the primary school science teachers to participate in the fun experiment development design after class.I hope to give some reference and put forward practical suggestions for students to participate in scientific experiments after class.An effective way of literacy.
