A Practical Study Of Project-based Learning In The Teaching Of Chemical Nutrients And Health

Project-based learning(PBL)is one of the important ways to cultivate students' comprehensive literacy in the 21 st world.It has been widely promoted and continuously studied in the world.It has experienced more than 20 years of development in China,and has been renewed for a long time.In the new curriculum reform,we should pay attention to the development of students' core literacy,from learning knowledge to developing literacy.And how to make the core literacy landing in the classroom is an urgent problem for front-line teachers to think about and solve.As a new carrier of changing education mode,project-based learning has aroused the attention of many education researchers.How to effectively carry out project-based learning and what changes project-based learning can bring to the classroom are worthy of our in-depth thinking and research.Based on the in-depth analysis of the connotation and characteristics of project-based learning,this paper combs the process framework of project-based learning,designs and practices project-based learning cases,and analyzes the significance of project-based learning to classroom reform through the practice results.This paper uses literature research,action research,questionnaire survey,interview,paper and pencil test and other research methods.The research content is divided into four chapters:The first chapter discusses the research background of this topic,expounds the development status of project-based learning at home and abroad,on this basis,defines the research objectives and significance of this study,combs the research methods to be adopted,and forms the research ideas.The second chapter discusses the connotation,characteristics and related theoretical basis of project-based learning in detail,compares project-based learning with other learning methods,forms a deeper understanding of project-based learning in comparison,and lays a good theoretical foundation for the practice of project-based learning in teaching.The third chapter combs the elements of project-based learning based on the previous theoretical research,and constructs the process framework of project-based learning implementation.The fourth chapter carries on the teaching design and classroom practice of "chemical nutrition and health" project-based learning,collects the results of classroom practice for analysis,and on this basis evaluates the changes of project-based learning to classroom teaching.The fifth chapter reflects and summarizes the research of this topic,and puts forward the prospect for the next step.
