在2011年版标准的课程目标中,“数学基本活动经验”被定为“四基”之一,把基本活动经验这个“软”目标提升为与双基同等地位的“硬”目标,可见其重要性。下面就结合教学中的相关案例来谈谈如何有效地让学生积累数学基本活动经验。一、积累“做”的活动经验1.创造“做”的时间与空间,培养几何操作的经验案例:长方体的认识(北师大版第八册)本节课教学我用了2课时,第1课时让学生直观操作,鼓励学
In the 2011 version of the standard course goal, “Basic Experience in Mathematics” was designated as one of the “Four Basics” and promoted the “soft” goal of basic activity experience to be equivalent to “ Hard ”goal, we can see its importance. The following combination of teaching cases to talk about how to effectively allow students to accumulate experience in basic mathematics activities. First, the accumulation of “do ” activity experience 1. Create “do ” of the time and space to cultivate the experience of geometric operation Case: Cuboid understanding (Beijing Normal University version eighth) This lesson I used 2 classes, the first class allows students to intuitive operation, encourage learning
