中文摘要 数学应用题是联系数学理论与数学实际的桥梁，在数学素质教育实施中越来越发挥重要的作用。数学应用题无论在教学实践还是在理论研究中都具有十分重要的意义。培养学生应用数学解决问题的能力，是数学教学的重要目的之一。 针对目前应用题教学难的事实，对“怎样提高初中生数学应用题解题水平”进行了研究。本文的研究从以下三个方面着手：第一，通过问卷设计进行了学生学习数学应用题的兴趣、动机、方法的调查。第二，运用设计的测试卷，进行了学生解应用题中思维过程的调查。报告了学生解决数学应用问题中存在的解题障碍的现状。根据初中生解决数学应用问题的解题障碍分析，归纳出提高初中生数学应用题解题能力的策略。第三，在教学中，设计、实践“应用题解题策略训练”的教学过程，通过对学生进行后测以及个案分析，证明应用题解题策略训练能够提高解题水平。 实验报告的数据证明，策略训练对解题水平提高具有实效性。根据初中生学习的特征，得出三条提高初中生数学应用题解题能力的策略。一、在应用题教学中要注意加强元认知调控；二、进行思维训练课干涉应用题解题；三、在教学中应用题教学中要注重语言转换和呈现方式的转换。研究表明解题策略训练一定会促进学生应用题水平的提高。帮助学生克服应用题解题的心理障碍，增强学生学习的自信心、自豪感。 关键词: 元认知；解题策略；数学应用题 Abstract Mathematics is the bridge between mathematical) heoryand the real mathematics, play a more and more important role in implementing mathematics quality education. Mathematics application problem has very important meaning whether in practice or in theory. Cultivating the students ability of applying mathematics to solve the problem, is one of the important aims of mathematics teaching. present the application topic teaching hard facts, on how to improve middle school students mathematics application problem solving level is studied. This paper studies from the following three aspects: first, through the design of the questionnaire survey, motivation, interest in students mathematics application problem. Second, by the design of the test, conducted a survey of students thinking in the process of application solutions. Present situation of problem-solving disorder reported students solve math problems. According to the analysis of solving mathematics application problem solving disorders of junior middle school students, the author summed up the junior high school students mathematics application problem-solving ability strategy. Third the author in teaching, design, practice teaching problem solving strategy training, through the analysis of the students post test and case, that problem solving strategy training can improve problem solving level. Experimental report data shows, with the effectiveness of st
