用技术的力量促进教学方式的变革——从赛灵格系统迭代更新看小学科学课堂教学的变化

Using the Power of Technology to Promote the Reform of Teaching Methods——On the changes of Science classroom teaching in primary schools from the perspective of iterative updating of Salinger system

数字化、信息化已成为时代的潮流。从2014年起,上海小学科学学科通过课例展示、专项培训、教学评优等方式,在小学科学课堂倡导数字化实验系统(DIS)的应用。DIS用小学生易于理解的数字来显示实验现象、突出教学重点、突破教学难点、形成科学概念,实现课堂学习时空的重新分配,使学生的科学学习变得更为有效。文章通过赛灵格系统的迭代更新阐述了信息技术支持下小学科学教学方式发生的变革。

Digitalization and informatization have become the trend of the times.Since 2014,Shanghai primary school science has advocated the application of digital experimental system(DIS)in primary school science classroom through lesson display,special training and teaching evaluation.Dis uses easy to understand numbers to show experimental phenomena,highlight teaching key points,break through teaching difficulties,form scientific concepts,reallocate classroom learning time and space,and make students’scientific learning more effective.Through the iterative updating of Salinger system,this paper expounds the changes of primary school science teaching methods under the support of information technology.
