1.注意培养学生的应用能力.奥赛题大多数取材于实际生活,常以简单的生活现象来隐藏复杂的物理过程.为了培养学生灵活运用所学知识简化实际问题的能力,在辅导中就要注意联系实际,进行必要的应用训练,帮助学生从表象中找出物理现象的实质.例如,给热水瓶灌开水时,可以利用声音的高低变化来判断瓶内的水是否满了,这是物理声学知识的灵活运用.还有家里厕所的下水道是利用连通器原理,医院输液打针是利用大气压原理等等.
1. Pay attention to develop students’ application ability. Most of the Olympic problems are based on real life. They often hide complex physical processes with simple life phenomena. In order to develop students’ ability to flexibly use the knowledge they learned to simplify practical problems, it is necessary to provide guidance. Pay attention to the actual situation, and conduct necessary application training to help students find the essence of the physical phenomenon from the appearance. For example, when the thermos is filled with water, the sound level can be used to determine whether the water in the bottle is full. This is physical acoustics. The flexible use of knowledge. There is the sewer at home toilet is the use of the principle of the connected device, the hospital infusion injection is the use of atmospheric pressure principle and so on.
