一、让抽象概念看得见,构建概念模型教学过程中运用直观操作,能调动小学生耳、眼、口、手、脑等多种感官参与学习活动,使学生的大脑保持兴奋状态,思维比较活跃,有利于学生形成完整的正确的概念。例如在教学“认识厘米”时,通过创设情景引出“厘米”这一单位后,我利用以下几个环节构建了“1厘米”的模型。看一看:让学生拿出尺子看一看,从0刻度到1刻度之间的长度就是1厘米。指一指:让学生从尺子上找出从哪儿到哪儿也是1厘米。学生回答时电脑显示这些线段。记一记:把拇指和食指放在尺子上
First, to make abstract concepts visible and to construct conceptual models The intuitive operation of the teaching process can mobilize the many senses of ear, eye, mouth, hand and brain of pupils to participate in learning activities so that students’ brains are excited and active in thinking , Is conducive to students to form a complete and correct concept. For example, teaching “understanding cm”, through the creation of scenarios lead to “cm” this unit, I use the following links to build a “1 cm” model. Take a look: Let students take a ruler to take a look, the length from 0 to 1 scale is 1 cm. Refers to a means: let the students find out where to go from the ruler is 1 cm. When the student replies, the computer displays these segments. Remember: Place your thumb and index finger on the ruler
