我市的广大农村中学,由于教学仪器、设备的欠缺,初中物理实验教学长期处于“一读二看三画”的阶段,学生的实验技能未能得到应有的培养.为了改变这种状态,近几年来,我们在部分中学开展了物理实验教学的“三自”活动,并初步显示出成效,现将我们的做法体会列后。 1.自制作:仿—改—创自制作就是学生根据某一实验教学要求,自己设计、制作小模型和实验器材.自制作活动大体分为三类。一是仿,就是模仿制作课本上的模型、实验装置和实验仪器.这是自制作的起点,借此培养他们初步的动手动脑习惯.例如,用细竹筒制作连通器和活塞式抽水机;用医用塑料瓶和塑料管制成压强计;用玻璃片连成船闸;用废玻璃管或废饮料瓶制作量简;用
Due to the lack of teaching equipment and equipment, the junior middle school physics experiment teaching has long been in the stage of “first reading, two watching and three paintings”, and the students’ experimental skills have not been properly cultivated. To change this state, In recent years, we have carried out the “three-self” activities in physics experiment teaching in some secondary schools, and have initially shown results. Now we have reviewed our experience. 1. Self-produced: Imitation - reform - create from the production is the students according to a certain experimental teaching requirements, their own design, production of small models and experimental equipment. Self-making activities are generally divided into three categories. The first is imitation, which imitates the production of models, experimental devices, and experimental instruments in textbooks. This is the starting point for self-production, thereby cultivating their initial hands-on and brain habits. For example, the use of fine bamboo tubes for the production of connected vessels and piston type pumping machines; Pressure gauges are made of plastic bottles and plastic tubes; ship locks are made of glass sheets; and the amount of waste is made from waste glass tubes or waste beverage bottles;
