初中学生年龄小,好奇心和求知欲都较强,在课堂上喜欢表现自己,但自我控制能力较差,注意力容易分散。如何针对初中学生的这些特点,设计处理好课堂提问,是提高课堂教学效果非常重要的一个环节。在多年教学实践中,我尝试采用下述几种提问方法,获得了较好的效果。一、联系学生的知识,层层深入提出问题,导入新课例如在讲解串联电路的特点时,我设计了如下问题:亮度可调节的台灯的亮度(或收音机音量的大小)与什么有关?答:与电流强度有关。改变电流大小有哪些方法?答:改变电压或电阻。改变电阻有哪些方法?
Junior high school students are young, curious and curiosity are strong, like to show in class, but poor self-control, attention easily dispersed. How to deal with these problems of junior high school students in class is a very important step to improve the effectiveness of classroom teaching. In many years of teaching practice, I try to use the following questions to get better results. First, to contact with students’ knowledge, put questions in depth and import new lessons. For example, when explaining the characteristics of the series circuit, I designed the following questions: What is the brightness of the adjustable brightness lamp (or the size of the radio volume)? : And the current intensity. What are the ways to change the current? A: Change the voltage or resistance. What are the ways to change the resistance?
