新课程标准要求,“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。现在大部分中学生存在着模仿能力较强,观察能力缺乏的弊病。因此,在数学教学中,教师应引导学生在解决数学问题时,从观 The new curriculum standard calls for “focusing on developing the mathematical thinking ability of high school students as one of the basic goals of mathematics education.” Observation is the beginning and source of intellectual activity and the prerequisite for human progress. From the perspective of cognitive process, thinking ability can be divided into four pairs of eight kinds of abilities: observation and attention ability (information collection); memory and understanding ability (information storage); thinking and inquiry ability (information processing); countermeasure and implementation ability Information application). No information is collected about the handling of information, so observation is the basis of other abilities. Nowadays, most middle school students have the disadvantage of imitating ability and lack of observation ability. Therefore, in mathematics teaching, teachers should guide students in solving mathematical problems
