《磁化和消磁》自编案例分析

Case Analysis of Magnetization and Demagnetization

跨学科教育方式能培养创新型复合人才,对于提升学生的问题解决能力、创新思维、创造能力具有十分重要的意义。将跨学科教育引入小学科学课堂的有效实践途径之一就是进行项目式学习。《磁化和消磁》自编案例以《研究磁铁》一课为基础进行拓展,进一步研究磁化后的缝衣针是否具有磁铁的性质,思考如何消去缝衣针的磁性。激发学生的探究兴趣,减轻学生学生压力,鼓励学生积极参与到科学学习中来。

Interdisciplinary education can cultivate innovative talents,which is of great significance to improve students’problem-solving ability,innovative thinking and creative ability.One of the effective practical ways to introduce interdisciplinary education into primary school science classroom is to carry out project-based learning.The case of magnetization and demagnetization is based on the lesson"study of magnets".It further studies whether the magnetized sewing needle has the properties of magnets and how to eliminate the magnetism of the sewing needle.Stimulate students’interest in inquiry,reduce students’pressure,and encourage students to actively participate in science learning.
