演示实验的可见度包括演示仪器可见度和实验可见度.演示仪器可见度是指让全班学生都能看清演示仪器的结构组成、装置设备;实验可见度是指让学生看清楚实验过程、实验现象以及能较准确地得出实验的数据,从而正确地得出实验结论,实验可见度直接影响到了实验教学的效果.本文从改进实验器材、优化实验过程、改良实验方法、改善实验环境四个维度探究如何增强演示实验可见度,打造高效物理课堂.
Visibility of the demonstration experiment includes demonstration instrument visibility and experimental visibility Demonstration instrument visibility refers to let the whole class of students can see the structure of the demonstration instrument, equipment and equipment; experimental visibility is to allow students to see the experimental process, the experimental phenomena and can compare Accurately derive the experimental data, so as to correctly draw the experimental conclusion, the experimental visibility directly affects the effectiveness of the experimental teaching.This paper explores how to enhance the demonstration from the four aspects of improving the experimental equipment, optimizing the experimental process, improving the experimental method, and improving the experimental environment Experimental visibility to create efficient physics classroom.
