一切智力活动都离不开观察,它是学生获得感性知识的开始,开启思维活动不可缺少的因素,数学上的观察是把形和数的特点进行直觉上的认识,通过观察认识数学命题中的数和形的特点、共性、差异。内在联系和隐含条件,为进一步解题提供可靠的线索,确定正确的解题方向。如何培养学生的观察能力呢?我认为可从以下方面着手:一、观察条件间的共性条件之间的共性表现在题中是某种规律性的东西,它常为解决问题提供可靠的线索。例如:看下面每行的前三个数,想一想接下去应填什么
All intellectual activities are inseparable from observation, it is the students get the beginning of perceptual knowledge, open thinking an indispensable factor, mathematical observation is the shape and the number of characteristics of intuitive understanding, through the observation and understanding of mathematical propositions Number and shape characteristics, commonalities, differences. Internal relations and implied conditions, to provide reliable clues for further problem solving, to determine the correct direction of problem solving. How to cultivate the students’ observation ability? I think that we can start with the following aspects: First, the commonalities between the common conditions of observation conditions are some regularities in the questions, which often provide reliable clues for solving the problems. For example: Look at the first three numbers below each line, think about what to fill next
