笔者认为,多媒体在初中数学教学中具有十分突出的作用,如利用幻灯、录音、录像等多媒体手段创设教学情境,把教师的“导”与学生的“探”有机地结合起来,就能很好地开启学生思维的闸门,大大提高教学效果。下面,笔者根据多年的教学实践,对此谈谈自己的粗浅认识。一、多媒体应用可提高学生的空间想像能力 In my opinion, multimedia plays a very prominent role in junior high school mathematics teaching. For example, it creates teaching situations through the use of multimedia tools such as slides, audio recordings and video recordings, and organically combines the teacher’s guidance and the student’s exploration. Can well open the gate of student’s thinking, raise the teaching effect greatly. Here, I based on years of teaching practice, to talk about their superficial understanding. First, multimedia applications can improve students’ spatial imagination
