The Research On Mathematical Appliance Problem In Middle Schools

Mathematics appliance problem, being a tie of mathematical theory and practice, plays a more important role in implementing mathematics quality education. The target is to fester and refine appliance awareness and intellect quality of the students, which will let every student can think over and solving problems mathematically. Teachers should pay more attention to appliance problem instruction, which can nurture the appliance awareness through the whole middle schools, train the ability of solving mathematically problem into everyday instruction, promote the development of mathematics innovation, stimulate their mathematics learning internet and develop their mathematics learning inner dynamic.In China, scores of mathematics teachers have already had a deep research in mathematics appliance problems instruction, making a great progress. But in daily mathematics appliance instructions, there also are lots of wrong ideas. How to instruct the appliance problem, today plays a lynchpin role in developing quality education reforms.The thesis, making a survey among teachers and having a test among students, gets such ideas about mathematics appliance problem as (1)teachers speaking about exercises more, students joining in, talking and thinking less;(2)analyzing in class more, opening all the channels understanding background less; (3)passing down, borrowing and collecting present exercises problem more, developing, innovating and making up new ones less. From above points the thesis draws the following conclusions; (4)the instruction research and practice in middle school mathematics appliance problem is not only to illustrate the usage of mathematics examples but to form the awareness of making students get the habit of using mathematics to solve problems by the means of mastering some reverent knowledge. This course is a capability education process, in which mathematical ability is important and together with mathematic intellect ability becoming the Key ability of solving practical problems.The main obstacles in working out the appliance problem for students are not toinBuild modeling rationally. So instructions can be divided into four layers according to the various levels: the first layer is to use math knowledge directly to build mathematics modeling: the second larger is to utilize present. Modeling to analyze in both quality and quantity; the third lager is to build mathematics by refined and ignore factors and their radiations between numbers and qualities; the froths is to analyze the cured practical questions and then build instructional modeling.Instruction strategies and practice spreads mainly on the following factors: 1. Strengthen practical teaching and stir students learning interest. 2. Break though the secret sense of problem background, smooth the students psychology abstracts. 3. Break through the level of abstract understanding; educate students mathematical ability. 4. From daily life, collecting and accumulating the materials of mathematics building modeling. 5. Join class teaching, practical exercises and inquiry learning closely together.Mathematical practice shows that appliance problem instruction tactic is not unmovable but changeable. The good of instruction lies on education the ability of students to leam new mathematics knowledge, mathematically raise, analyze and settle problems, including expressing their thoughts mathematically, and developing their appliance and innovation awareness.The thesis only discusses and practices from individuality and lots of work need to be some.
