教师引导学生利用周末观察、搜集当地苗族蜡染、银饰、芦笙制品等,寻找一元一次不等式组信息,结合数学课本上的知识自主编题,教师在“一元一次不等式组的拓展”教学中展示学生编制的题目,并以这些题目为主线开展教学.教学中师生相互配合,学生的学习兴趣盎然.这样的教学既巩固拓展了所学知识,又培养了学生对知识的获取能力和解决实际问题的能力.更为难能可贵的是课堂融入苗族文化元素作为教学的题材,让学生自己编题,自己解决问题,从而渗透了苗族文化,使学生在自己熟悉的文化背景中进行数学学习.
Teachers guide students to use weekend observation to collect local Miao batik, silver ornaments, Lusheng products, etc., to find the information of unary inequality groups, combined with the knowledge of mathematics textbooks on the independent coding, teachers in the “one dollar inequality group expansion ” teaching show Students to develop the subject, and these topics as the main line of teaching .Teaching teachers and students complement each other, students interest in learning .This teaching not only consolidate and expand the knowledge learned, but also cultivate students’ ability to acquire knowledge and solve practical problems Problem.More valuable is the classroom into the Miao elements of culture as a teaching theme for students to compile their own problems, to solve the problem, thus penetrating the Miao culture, so that students in their familiar cultural background for math learning.
