《义务教育数学课程标准》指出:培养学生观察能力是数学教学中的根本任务之一,从心理学角度看,观察是思维之初,培养观察能力,对思维的发展具有重要的意义。现在的初中数学教学中,存在着学生学习质量不高,课堂教学效率低下的弊端。可见,耍点花样,弄点噱头,培养提高学生的观察能力,是改革数学课堂教学的重要切入点和突破口之一。教师在教学的各个环节中应落实观察的手段,充分显示这一教学观,切实重视学生观察能力的培养。
“Compulsory Education Mathematics Curriculum Standard” points out: Cultivating students’ observation ability is one of the fundamental tasks in mathematics teaching. From a psychological point of view, observation is the beginning of thinking and developing observation ability, which is of great significance to the development of thinking. In junior middle school mathematics teaching nowadays, there are some shortcomings such as poor quality of learning and inefficient classroom teaching. Visible, play tricks, get some gimmicks, training to improve students’ ability to observe, is an important breakthrough point in the reform of mathematics classroom teaching and one of the breakthrough. Teachers in all aspects of teaching should implement the means of observation, fully demonstrate this teaching concept, pay attention to the cultivation of students’ observation ability.
