“一次函数的图象”一节课的教学,主要是通过学习画函数图象来培养学生的画图技能,通过图象揭示函数的性质,培养学生观察、比较、抽象和概括的能力,培养学生用数形结合的思想方法解决数学问题的能力,培养学生的应用意识和创新意识.这一课的目标是要引导学生完成由函数解析式到函数图象的思维转换.为了顺利完成这一思维的转换过程,苏科版教材安排了一个教学情境:将一支长16cm的香点燃后,香的长度随着点燃时间的
The teaching of “one-function image ” class mainly aims to cultivate students ’drawing skills by learning to draw function images, revealing the nature of the function through images, cultivating students’ abilities of observation, comparison, abstraction and generalization, Train students ’abilities to solve mathematical problems by the combination of ideas and methods, and train the students’ sense of application and innovation.The goal of this course is to guide students to complete the conversion from functional analysis to functional image thinking.In order to successfully accomplish this A conversion process of thinking, Suke Edition textbook arranged a teaching situation: a 16cm long incense ignited, the length of the incense with the ignition time
