论文部分内容阅读
从初中新教材内容来看,这部分内容大多是定性的,表面上看来,难度不是太大,但初中学生初次接触,学习内容和方法不一定适应,学起来困难,主要原因是这部分内容不像力学中质量、路程、速度等概念那样直观,而具有一定的抽象性,学习时只有在观察、实验的基础上取得丰富的感性材料,经过头脑加工,理论联系实际,从生活走向物理,进一步激发学生学习物理的兴趣,达到所期望的效果。笔者认为教学中要注意以下几点:
From the junior high school textbooks, this part of the content is mostly qualitative, on the surface, the difficulty is not too great, but junior high school students first contact, learning content and methods may not be adapted to learn more difficult, mainly because of this part of the content Unlike mechanics, such as quality, distance, speed and other concepts as intuitive, but has a certain degree of abstraction, learning only on the basis of observation and experiment to obtain a wealth of perceptual material, through the mind processing, theory with practice, from life to physics, Further stimulate students interest in learning physics to achieve the desired results. I think the teaching should pay attention to the following points:
