The Investigation Of Incorrect Intuition In7th Grade Probability Learning

In the study of probability, the research about probabilistic incorrect intuition is getting theattention of many researchers. This paper analyzes the relevant research and current situation ofthe incorrect intuition in7th Grade probability learning by literature method. The incorrectintuition in probability learning is divided into three types: concept, operation and proportionalreasoning, which are investigated by means of questionnaire and interview.The result of the research shows that the incorrect intuition in7th Grade probabilitylearning exists mainly in the understanding and mastering of concepts, the incorrect intuition isrevealed correspondingly less in the operation and the proportional reasoning. The conclusionof this paper is that7thGrade students mastering of probability is not satisfactory, and that theboys are a little better than the girls in the mastering of the knowledge of probability. Alongsidewith the concept of the ability of probability reasoning, but the difference is not significant. Asthe students ability of probabilityreasoningandtheir ability of proportional reasoning developtogether with each other. Yet within the method of teaching of probability in primary schools iscorrespondingly single. At last, this paper gives some suggestion about the teaching ofprobability, the mathematic course and the professional development of the teachers.
