弗莱雷认为,对话是教育的主要途径之一;要使对话有成效,提问是关键.那么,如何设置问题才能使学生不断地有所发现、有所创新呢?下面摘取两个教学片断和大家共享.片断一:测小灯泡功率.选择电压表量程师:我们现在使用的小灯泡额定电压是3.8 V,要测出小灯泡的额定功率,应该使用电压表的哪个量程?生:用0~15 V 量程.师:请大家按实验要求连接电路,并按实验步骤完成数据
Freire believes that dialogue is one of the main ways of education; asking questions is the key to making dialogue effective. Then, how can students be found and innovated by setting up questions? Here are two teaching clips. Share with everyone. Fragment 1: Measuring the lamp power. Select the voltmeter. Range division: We use a small bulb with a rated voltage of 3.8 V. To measure the rated power of a small lamp, which voltmeter range should be used? 0 ~ 15 V range. Division: Please connect the circuit according to the experimental requirements and complete the data according to the experimental procedure.
