一、富有“联系”的教学设计所谓联系,是指教学设计要联系学生的客观现实和数学现实,使教学内容不是空洞无物的,而是有意义的,是与学生已有经验、知识相联系的。有效的数学教学,需要教师准确地掌握教学起点,从教材的知识体系及学生已有的知识,经验等方面整体出发,更多的关注情境与知识的连接点,创设富有数学韵味和思考价值的情境,以利于促进学生已有知识与经验的迁移,主动进行新知的构建。例如“倒数的认识”新课引入,教师谈话:“同学们开学至今已一个多月了,经过这一个多月的接触,老师和大家建立了亲密的关系,相互成了——朋友(师生齐说)。谁来解释一下,你是怎样理解‘相互成了朋友’的?日常生活中有很多像这样有着相互关系的现象,你能举一些例子吗?(父女关系,他是我的父亲,我是他的儿子;师生关系,你是我的老师,我是你的学生 First, the rich ”contact “ teaching design The so-called contact, refers to the teaching design to contact students objective reality and mathematical reality, so that teaching content is not empty nothing, but meaningful, and the students have experience, knowledge Related. Effective mathematics teaching requires teachers to accurately grasp the starting point of teaching, starting from the teaching material knowledge system and students’ existing knowledge and experience as a whole, pay more attention to the connection between context and knowledge, and create rich mathematical flavor and thinking value Situation, in order to facilitate the transfer of existing knowledge and experience of students, take the initiative to build new knowledge. For example, ”The Countdown to Recognition “ new class introduced, the teacher talk: ”Students have been studying for more than a month has passed, after more than a month of contact, the teacher and everyone to establish a close relationship, mutual became - friends (Teachers and students alike.) Who will explain how you understood each other as friends? There are many interdependent phenomena in everyday life. Could you give some examples? (Father-daughter relationship, Is my father, I am his son; teacher-student relationship, you are my teacher, I am your student
