Research On Implementing Project-Based Learning In Primary School Science

As a fundamental,practical,and comprehensive course aimed at developing students’ scientific literacy,primary school science has a crucial role to play in shaping students’ scientific attitudes and skills.In recent years,project-based learning(PBL)based on real-world problem-solving has received increasing attention as a means to stimulate and sustain students’ interest in scientific learning and lay a strong foundation for their lifelong development.Drawing on his own experience of PBL during graduate study,the author embarked on a research project to design and implement PBL in primary school science education,using the topic of "designing and making an intelligent posture corrector" as the focus.Specifically,the study addressed the following questions: First,how to design problems that sustain students’ motivation and engagement in PBL? Second,how to evaluate students’ growth and progress in developing their abilities during PBL? Third,what are the effects of PBL on teaching and learning in the case of designing and making an intelligent posture corrector?To address these questions,the author utilized a combination of literature reviews,action research,and questionnaire surveys,and conducted the following steps: First,by integrating relevant literature on PBL in primary school science education,the author designed and implemented the PBL on intelligent posture correctors.Second,by reviewing the relevant literature on teaching practices related to posture correction,the author evaluated the effectiveness of the PBL through designing,implementing,and evaluating the teaching process.Finally,the author analyzed the pre-and-post-test questionnaire data,work performance evaluation,and Williams creativity tendency scale to draw conclusions.The study produced the following findings:First,by using authentic and challenging problem scenarios,breaking down driving problems into "problem strings," and using questions to drive students to complete tasks,students are more likely to engage in PBL.Second,PBL can be evaluated through formative evaluation as the main approach and summative evaluation as a supplementary approach,which helps to record students’ growth.Third,PBL can inspire students’ creativity,enhance their scientific inquiry skills,and promote their scientific literacy development.From the author’s own research experience,five teaching suggestions were proposed:First,designing driving problems that arise from real-life situations and are challenging;Second,establishing a "problem string"-"task chain"-"project" model;Third,using multiple evaluations;Fourth,establishing open classrooms;Fifth,creating a sense of awareness for laboratory management and maintenance.Through practice,the study demonstrated that PBL-oriented design and implementation of primary school science education can to a certain extent enhance students’ interest and motivation in science learning,improve their problem-solving abilities and creativity,and promote their scientific literacy development.
