一、教学设计思路本节是规律探究课,在教学方法上,采用“任务驱动”教学法,即以学生为中心,以任务为载体,把教学内容巧妙地隐含在一个个具体任务之中,学生通过独立或协作完成任务,学习新知识和新技能.主要特色为:(1)本文设计了实验探究安培力的方向与磁场、电流的方向关系;理论探究安培力大小的表达式;揭秘电磁轨道炮和了解磁电式电表的工作原理等学习任务,使学生在任务解决中学习到新知识和新技能.
First, the teaching design ideas This section is the law of inquiry, teaching methods, using “task-driven ” teaching method, that is, students as the center, the task as a carrier, the teaching content subtly implicit in a specific task Among them, the students accomplish the task through independent or collaborative learning new knowledge and new skills.The main features are as follows: (1) This paper designed the experimental exploration of the relationship between the direction of ampere force and the magnetic field, the current direction; theoretically explore the Ampree force size expression ; Uncover the electromagnetic rail gun and understand the working principle of magnetoelectric meters and other learning tasks so that students learn new knowledge and new skills in the task to solve.
