今年暑假我有幸参加南通市李庾南数学骨干教师的培训,听了闵晓穎老师的一堂课.这堂课是人教版数学九年级上册“二次根式”第一课时.一、教学目标的制定课标要求:学生要学会学习、自主学习,要为学生终身学习打下坚实的基础,因此,根据数学课程标准中关于“二次根式”的教学要求,结合教材内容以及学生的实际情况,本节课的教学目标如下:了解二次根式的概念,通过对二次根式的概念探究,提高数学探究能力和归纳表达能力.学生 This summer I was fortunate enough to participate in Nantong Li Junan mathematics backbone teacher training, listening to Min Xiaoying teacher a lesson .This lesson is the PEP mathematics ninth grade book “secondary root ” the first lesson. According to the teaching requirements of “secondary root ” in the standard of mathematics curriculum, combined with the content of teaching materials and the actual conditions of students, the students’ The teaching objectives of this lesson are as follows: Understand the concept of quadratic root, through the concept of quadratic root to explore and improve the capacity of mathematical inquiry and induction of expression.
