新课程标准中要求,“注重培养高中学生的数学思维能力是数学教育的基本目标之一”.观察是智力活动的开端和源泉,是人类获得进步的前提.从认知过程的角度,思维能力可以分为四对八种能力:观察、注意能力(信息收集);记忆、理解能力(信息储存);思考、探究能力(信息加工);对策、实施能力(信息运用).没有信息的收集何谈信息的处理,所以观察能力是其它能力的基础. The new curriculum standards require that “focusing on developing the mathematical thinking ability of high school students is one of the basic goals of mathematics education.” Observation is the beginning and source of intellectual activity and is the prerequisite for human progress.From the cognitive process perspective, Thinking ability can be divided into four pairs of eight kinds of abilities: observation, attention ability (information collection); memory, understanding ability (information storage); thinking, inquiry ability (information processing); countermeasure, Collecting information about how to deal with, so observation is the basis of other capabilities.
