Research On High School Students Understand The Concept Of Probability In The New Curriculum

Along with the implementation of a new round of basic education curriculum reform in our country, the probability of not only plays an important role in solving practical problems, in the process of high school mathematics learning also occupies very important position. So the students’understanding of the concepts of probability? What are the wrong? This research defined by the student to the probability of frequency, the classical scheme, geometric model and computer simulating test four aspects to understand the students’ understanding of the concepts of probability.In this study the first chapter expounds the research background, present situation and proposes the research problems and significance; The second chapter for mis research to understand the relevant concepts of probability analysis; The third chapter the author to literature analysis and teaching experiences found students’ understanding of the concepts of probability of error as the basis, the research methods of this study was compiled; The fourth chapter in view of the questions in the questionnaire type respectively from1. Events in May and may not, he will understand the results of a survey and cause analysis;2. The "frequency" and "probability" concept to understand the results of a survey and cause analysis;3. The investigation results of "classical scheme" understanding and cause analysis;4. To understand "geometry scheme" and cause analysis of the investigation results,5. The understanding of "computer simulation experiment" results and cause analysis of five aspects analyzes the concept of probability high school students to understand the situation.Through the above four chapters of analysis and summary, the author in chapter5gets the following conclusion:l.The student to the impossible, possible, certain event is better and judgment could not, probably, but most of the students is the basis of a certain event main life common sense.2. The students’understanding of the concepts of probability and frequency also exist a lot of misunderstanding, two relations easily confused. That frequency is probability.3. The prediction method is one of students in dealing with probability often mistake, compare it with some students in the50%will be given after a certain event occurs or not accurate judgment, this peace with daily teaching students receive education about rigorous mathematical thinking.4. Nearly50%of the students understanding of classical scheme in fuzzy state, did not understand the meaning of basic events, such as possible events.5. Students dealing with geometric scheme mechanical calculation is more, really understand the nature of geometry scheme is less.6. The student to use the method of computer simulation to estimate the probability of ability is poor, especially the little computer simulated the process of understanding.
