| In order to meet the challenges of the future, our country should implement of the strategy relying on science and education. Our country should do full implementation of quality education and do National implementation of basic education reform.The content of the science is very wide. It is divided into three areas:the material world, life, world, earth and universe. It covers four major areas:biology, physics, chemistry and geography. By setting up science students acquire and use knowledge. At the same time, it can improve the students’ability and quality. But there are also some problems:the limitation of the condition and curriculum, teaching methods and so on.Money and equipment are the first condition for the implementation of science curriculum to normal. The choice of teaching methods is the key to launch for a long time science courses. The study aim at a serious of design teaching activities.First, through detailed investigation of primary and secondary schools, found that most of the front-line teachers set up the way of taught to teach "buoyancy". This study combined the paper bearing problem with the knowledge of the buoyancy, and launched a series of activities.Second, to select the low A4 paper as the main teaching material, to choose recycled coins as auxiliary material. Common things in life can stimulate the students’ desire.Then, the ultimate goal is how we could make good A4 paper carry more coins. In the process, the teacher will design a few small targets. For example, the relationship of the bearing weight of the paper and the volume of paper, what most paper boat in the shape of its beating capacity, predicting the bearing capacity and load of paper and real between the source and so on.Finally, to make it more scientific, this paper has carried on the class at the same time. And it is modified.There is a gap between designing and implementation. A good exploration class needs the quality of the teacher and the attention of the students. |
