The Practical Study On Cultivating The Problem-awareness Of Students In Mathematic Teaching In Junior Middle School

Problem posing is a source of originality, which is an important part of effective learning of the students. It is not only the basis for solving problem creatively, but also the start and the result of teaching activities. Essentially, originality is a process of the discovery of the problems as a beginning to the solution as an end., which will bring the needs and internal driving force to settle the problems , and to inspire people to create. Problem-awareness is the premise of posing problems. By making a question-situation and democratic class, the teacher can help students to train their thoughts and cultivate the ability of posing problems. In this way, students can improve their ability to solve mathematical problems, training their mathematical thinking, and enhance their creativity, which junior high school math teachers have been focus on.Currently, the training of problem-awareness concentrates on how to guide students to solve problems, instead of how to guide students to find out and raise the problems by themselves. On the basis of the studies on the cultivation of problem-awareness of junior high school students in china, the author thinks about the following questions: (1) What is the present situation of the posing problems by students themselves in junior high school students (2) How to deal with students'questions in class? How to cultivate the problem-awareness of students? To have a comprehensive understanding of present situation of the posing problems, the author interviews many teachers, arrange a book of recording questions, have training class, analysis some examples, discusses the ways of cultivation of problem-awareness of the students, does some experiments on students in Grade 9 combining with her teaching experience of twenty years. Finally, the results demonstrate the teaching strategies are effective and feasible.The research and experiments of this topic show that mathematics teaching should pay attention to the cultivation of students'problem-awareness. In order to develop the original thinking, teachers should make a relaxing atmosphere, set the problem-situation carefully and improve their critical faculties by taking positive and effective teaching methods and measures.
