实验教学是初中物理教学不可缺少的环节,是实现教学目的的重要途径.现实中受环境、设施、各种条件等诸多因素的影响,实验教具不能完全适应课堂教学的需要,教师和学生就应改变观念,就地取材,自己制作教具.自制简单的物理教具,一则方便教师教学活动的开展;二则有益于培养学生的观察能力和实验能力,使学生更主动地参与到科学探究中去,建构物理概念和规律时“事半功倍”.案例1在人教版九年级物理第十二章讲授“速度测量”
Experimental teaching is an indispensable part of junior high school physics teaching and is an important way to achieve the goal of teaching.In reality, influenced by many factors such as environment, facilities and various conditions, experimental teaching aids can not fully meet the needs of classroom teaching. Teachers and students should Change ideas, get the materials locally, make their own teaching aids, create simple physical teaching aids, and facilitate the teaching activities of teachers. The second is beneficial to students’ observation and experiment ability, and make students take a more active part in scientific inquiry , The construction of the concept and the law of physics “case with less. ” Case 1 in the PEP ninth grade physics twelfth chapter “speed measurement ”
