STEM理念下大班科学教学的实施与探析

The Implementation and Analysis About Teaching Method of Scientific Education in Senior Kindergarten Under STEM Concept

STEM理念下科学教学的实施变革主要表现为教学内容融合化、教学方法项目化和教学资源多样化。在大班技术操作型活动中应用工程设计思想,加入产品的测试与优化环节,进一步激发幼儿的批判性思维,促进其创造力的发展。教学过程分为精准备课、高效上课和及时评价,其中精准备课要分析幼儿的特点、合理选择与投放活动材料等;高效上课渗透工程设计的思想开展活动,并描述三种模式下的教学环节和具体案例;及时评价强调着眼于幼儿的整体表现,进行综合评价。

The specific contents of implementing reform of scientific teaching mainly manifested as the integration of the teaching contents,the projectization of teaching methods,and the diversification of the teaching resources on the basic of the concepts.Applying engineering design ideas in the technical operation activities of the senior kindergarten,and adding product testing and optimizing process can further stimulate children’s critical thinking and promote the development of their creativity.The teaching process is divided into the preparation of an accurate lesson,efficient class,and timely evaluation.Specifically,the preparation of the accurate lesson is to analyze the characteristics of children,so as to rationally select and deliver the materials for activity,the efficient class mirrors the methods of the engineering design to carry out activities,the timely evaluation focuses on children’s overall performance and conducts comprehensive evaluation.
