摘　　要： 数学应用题表征类型中的外部表征的影响因素，主要包括文本表面特征、数学符号、文本内容熟悉程度、插图、问题与文本的呈现位置、不同的措辞、情境内容的现实性等．未来可以从以下几个方面进行进一步研究：对不同复杂程度情境背景的应用题而言，题材熟悉度对应用题表征的影响如何？动态呈现方式本身以及动画呈现中的颜色、形状等无关信息对问题解决的影响程度如何？在儿童理解和解决数学应用题过程中，强调情境模型构建的5个维度中的哪些维度更有利于学生理解应用题中的数学关系，以便构建合适的情境模型，进行正确的数学表征？ Some factors of affecting the external representation of math word problems mainly contain the surface features of text, mathematical symbols, text familiarity, illustrations, problems and text of location, different rewordings, the reality of situational content and so on. Some studies can be advanced from the following aspects in the future： for the math word problems of situational background of different levels of complexity, how text familiarity affects the representation of math word problems？ How dynamic conditions itself and the irrelevant information which contain color, shape etc in animated presentation affect the problem-solving in some degree？ In the process of children＇s understanding and solving math word problems, which dimensions are more important to help the students understand mathematical relationships in math word problems when are emphasized in constructing situation model, in order to construct appropriate situation model, conduct correct representation of math word problems？
