Junior High School Mathematics Open Question And Its Teaching Research

In China, as the course reform of basic education is popularized progressively and carried out deep, the open mathematics questions become the hot topic, which are discussed by scholars in the educational field. So they are put into mathematics textbook gradually, and are also utilized to the course of classroom teaching by degrees. Teaching of open questions gives expression to educational concept of the mathematics curriculum reform, and achieves that goal, which combines traditional quality education with innovation of education together organically and closely. It is the offset of the traditional education. Not only on account of being beneficial of coming to understand and grasping the basal knowledge and skills, but also in favor of stretching students' thinking and acquiring their abilities. In the procedure of teaching, three main parts are there, which are separately the teaching material, the teacher and the student. It is well known that one of main bodies, the teacher is the principal part of the classroom teaching, and the student in the learning himself or herself, teaching material in the full process, that is just like a bridge of linking up the others and that is the community of the above. Teaching material is a significance gist of teaching by teachers and a powerful tool of obtain indirect experience by students, at this point whose significance be able to accounted. Based on the cognition, I in this thesis do research about the ?pen-ended questions of content from statistics and probability, mainly aimed at teaching material of Beijing Normal University edition. In accordance with the teaching principle, and specific content, I propose some strategies of implementing the teaching as a carrier to open-ended questions teaching through the classification and comparison of open-ended questions, additionally getting in touch with teaching situation in actually.The specific arrangements are as follow:1, first, elaborate the cause, purpose, significance and methods of research mainly on studying the open-ended questions and teaching as a main content for them.2, second, on the one hand,integrate and summary the operating situation with respect to the open-ended questions and teaching as a carrier to them in detail at home and abroad, by means of checking out and sorting out the many relational issues and literatures; on the another hand illuminate the involved concept, characteristic, classification and teaching theory of the mathematics open-ended questions briefly.3, third, for one thing, put forth effort on collecting information of open-ended questions and analyzing them in many ways pertaining to statistics and probability. For another, exert myself into making a summary and impact analysis of interview survey.4, fourth, in line with teaching principle, make an attempt on putting forward some proposal and strategies about open problems teaching and conducting instructions by the instance of teaching.5, the last, do summary of the thesis, including the possible deficiencies in the course of study.
