Acquisition Of The Degree Of Junior Two Physical Problem Solving Study And Practice Factors

In current learning and teaching theories, it is very few that the literature about the use of problem-solving and cognitive strategies in junior physical teaching. However, teachers and students of junior schools are eager to know about the relations of physical problem-solving study and practice factors, which is in order to improve teaching-design, learning-methods and the quality of education. The article tries to do some research in junior two physical problem solving study and practice factors which includes the quantity, time-spending of exercise problems and relation of problem solving and them.. The aims is helping to improve the quality of education.The testee of this research is six classes junior 2 students in Jiangsu province. R is the accuracy, which means problem solving study. N is quantity of exercise problems. T is time spending in exercise problems. The object of this research is physical complicated calculating problems, which practices three times. There are two groups in each practice. One is for the relation of problem solving discovery probability. The other is for the relation of problem solving master level and practice factors. The relation of N(or T) and problem solving separates in different group.It can conclude by the practices:Problem solving discovery probability isn't obviously related with N and T. Problem solving study isn't obviously related with T but N, when increase the quantity of exercise problems.The suggestion based on results of research is:on improving the efficiency of education, it can make students master methods well and improve the quality of education by the examples of problem solving, increase of N (2～3 every time) and strengthening for 2-3 days, suitable but not much time for every exercise problem.
