CAI是计算机辅助教学英文名的简称,如果把它进行简单的“加工”(即改为小写的形式“cai”),再加些“佐料”(标上声调“、”),就成了一道“cài”(菜)。那么这道“菜”的味道究竟如何呢?品尝过后,你定会感叹:这确实是一道好“菜”! 例如《圆的面积》教学时,我正是通过CAI,取得了很好的教学效果。下面就此谈谈我的体会。一、利用计算机快速的再现性,复习迁移。 “圆的面积”的教学,是在学生初步学会运用“转化思想”推导平行四边形、三角形、梯形面积公式的基础上进行的。由于这些知识是在前几个学期学过的,部分学生可能已经遗忘,我利用计算机再现快的优势,设计了一个“小小魔术师”的游戏课件(如图1,提示虚线后来添加,可演示拼补过 CAI is short for computer-aided instruction English name, if it is simple “processing” (that is, change to lowercase form “cai”), add some “saucer” (marked tone “ , ”), It becomes a“ cài ”(dish). After taste, you will lament: This is indeed a good “dish”! For example, “round area” teaching, I was obtained through the CAI Very good teaching results. Here to talk about my experience. First, the use of computer rapid reproducibility, review migration. The teaching of “circle area” is based on the initial derivation of the formula of parallelogram, triangle and trapezoid area by the students using “transformation thinking”. Because of this knowledge was learned in previous semesters, some students may have forgotten, I use the computer to reproduce the advantages of fast, designed a “little magician” game courseware (as shown in Figure 1, suggesting the dotted line was added later , Can be demonstrated to make up
