Classical probability of teaching in secondary schools.doc

Classical probability of teaching in secondary schools Abstract probability and statistics is the focus of the University of many professional courses, especially the Department of Mathematics, on behalf of the class to write a required thesis. In recent years, secondary schools increased the number of preliminary knowledge of probability and statistics, in the entrance examination questions are in the questions on probability and statistics are also increasing. But the textbook knowledge and put it on the shallow, narrow range of knowledge, leading students to learn and easy to understand but difficult to solve problems. Therefore, appropriate knowledge should be expanded to adapt to the new situation. Keywords: Secondary School Teaching of Classical Probability Department of Mathematics, College of Zunyi County Middle School students in each attachment period, where the practice of schools teaching the investigation. Focus was to investigate the probability and statistics course the teaching and learning in secondary schools. Through the investigation of the conclusions they arrive at a consensus, probability statistics on this course, secondary school textbook speaks shallower, causing students to learn and easy to understand but difficult to solve problems. Unanimously to expand the knowledge required to make appropriate in order to adapt to the new situation. A student said: “Over the last few years, university entrance, quite a lot of talk about the probability of scoring rate is low, especially in regard to classical probability exam,” focusing on this issue during the internship period, he conducted a survey of Zunyi county, the Grade School year more than 800 students, from a random sample of 50 students, to investigate the application of probability and statistics. Survey results are as follows: From the above table can be clearly seen: the ratio is clearly inconsistent with the normal distribution. The student wrote: The reason, accord
