The Application Of "Problem Chain" In High School Mathematics Teaching

A problem is presented by asserting. Particular emphasis is the heart of the American mathematician HALS once said: "the problem is mathematics".Mathematics learning always starts with the problem and finally the problem, the new curriculum reform requires learning problems in learning the importance of a problem to study the problem as a learning starting point and power throughout the entire process of learning; on the other hand, by learning to generate problems,deepening the learning as is found, put forward, analysis and solve the problem of uninterrupted process. But the reality of classroom teaching problems are often scattered, disorderly and numerous, complex, the quality varies greatly, so how to improve the teaching quality to be placed in each An issue that needs to be settled by an educator.On the basis of clarifying and summarizing the research of others, this study mainly carried out the following research:First, the "chain" and related concepts defined, in the constructivist learning theory and the "zone of proximal development" in the theoretical foundations of psychology, select the three teaching fragments and a complete teaching case, try to use the design concept of "chain", the issue of classroom organization guide specific teaching and to observe the effect of teaching.Second, using the literature research method combined with their own actual teaching experience, put forward designing process from the two aspects of designing principles and strategies, with a view to the research behind the practice: case analysis provide theoretical guidance.Third, combined with their own actual teaching and the demonstration lesson demonstration analysis, from the point of view of the practice of "question chain" design do some study, through analysis and research of case teaching, step test and improve the design of front chain problem, then draws a conclusion that "chain" design should not only reflect the mathematics "double base" teaching requirements but also to contain the thinking of mathematical way of thinking training.
