人教版六年制小学自然第六册第11课《磁铁的性质》继学生认识了磁铁有吸铁的性质之后,继续指导学生认识磁铁有指示南北和同极相斥、异极相吸的性质。教材的编写思路是:①通过实验认识磁铁有指示南北的性质,然后告诉学生两个磁极的名称。②把磁铁的任意两个极互相接近,然后归纳概括磁铁同极相斥、异极相吸的性质。③巩固磁铁的性质,应用新学知识解决问题。
PEP 6 Sixth Year of Nature, Volume 6, Chapter 11 “Properties of Magnets” Following the students' understanding that magnets have the property of attracting iron, students continue to guide students to recognize magnets that indicate North-South and South-South repulsion and heterodoxy nature. The preparation of teaching materials is: ① through experiments to understand the nature of North and South have instructions magnet, and then tell the students the names of the two poles. ② the magnet of any two poles close to each other, and then summed up the same magnet repulsion, extremely polar nature. ③ to consolidate the nature of the magnet, the application of new knowledge to solve the problem.
