Junior Middle School Probability Teaching Investigation And Research

In nature and the human society, the strict definite phenomenon is extremely limited, the indefinite phenomenon (called stochastic phenomenon) actually is the massive existences. Moreover, the probability already has closely been connected with people's routine work and the social life. The life ,ahead of mathematics curriculum presents the probability in front of students . It may help the student through the probability study to know well the world and clarify some intuitions errors; It can effectively train the student through the probability study to have the sense and the ability of activity research and reasonable inference .It may expand student's understanding domain through the probability study, promote knowledge grasping and migration, inspire their thinking and fully develop mathematics ability.Along with the curriculum reform unceasingly thorough problems, in the probability teaching fundamental research and the practice teaching question gradually expose. Facing the multitudinous question, this year, among the partial teachers we have carried on a survey about probability questionnaire. And we have earnestly analyzed the investigation result. In teacher basic situation and study condition, curriculum goal, curriculum depth, curriculum content, curriculum experiment, calculator teaching realization and so on, all varying degree questions exist. But these questions mostly concern with the teacher. Probability curriculum educational reform: Road in where? Road on under our own feet! The author thinks great efforts should be made to the following: Teachers should accurately assure teaching goals and guarantee their realization; control the depth ,trying to make it as simple as possible ; Fully pay attention to activity class; Set up synthesis appraisal view.The teaching material content is the basis for teaching , it is also the main material which the students study. The teacher not only wants to study the scientific nature of the teaching material, moreover must study logic and t systematic characterristic. Form the classroom instruction pattern. Fully provide the opportunity in the classroom instruction for the student to carry on mathematics practice activities and exchange their notes, use the independent exploration, the cooperation exchange, the operating practice study way and cause them to obtain the widespread mathematics activity experience in the independent exploration process. The information technology and mathematics teaching discipline conformity in the current educational reform is a matter of concern, where conditions are available in the teaching, the multimedia teaching should be used as far as possible to enhance the teaching efficiency.As a mathematics teacher, we not only promote the idea but also have to supplement the knowledge; It's necessary carry one sential teaching reconsidering in the teaching and unceasingly grow in the practice - - reconsidering - - practice - - reconsidering circulation reciprocation process. Encourage the student in the classroom instruction independently to explore and the cooperation exchange and process the good work mobility and the speculate relation; Value probabilistic model formation and discrimination;Take student's interest and raise the confidence; Value the raise of reading ability and research method. Especially pay attention to student's emotion experience in the process appraisal; Take to the independent learning capability and the self- development ability appraisal.
