《新课标》中指出:“我们的数学要尽可能紧密联系学生的生活实际,从学生的生活经验和已有的知识出发。”通过电教媒体,将数学知识与学生的生活实际联系起来,妙用多媒体教学,让数学与生活紧密相连,只有这样,才能提高数学课堂教学的效率,促进学生的全面发展。下面结合自己的教学实践,浅谈一下电教手段在小学高年级数学中的应用一、电教手段是调和剂,激发学生学习数学的兴趣如教学《圆的面积》时,教师从“神舟五号”的降落范围引导出就是求圆的面积,从而提出问题“怎样求圆的面积呢?”
The New Curriculum Criteria states: “Our mathematics should be closely linked to students ’actual life as closely as possible, starting from the students’ life experiences and existing knowledge.” Through the use of audio-visual media, the actual connection between mathematical knowledge and student life Up, Magical multimedia teaching, so that mathematics and life are closely linked, the only way to improve the efficiency of mathematics classroom teaching and promote the all-round development of students. The following combination of their own teaching practice, talk about the use of audio-visual means in the high school mathematics in primary school one, audio-visual means is a mediator to stimulate students interest in learning mathematics such as teaching “circle area”, the teacher from the “Shenzhou V ”The scope of the landing leads to the area of the circle, thus raising the question “ How to find the area of the circle? ”
