摘要本研究旨在探讨中学生在真实的生活情境中，在几何与测量领域的比例推理、解题策略与困难。并对造成这些困难的根本原因进行了探讨。本研究采用混合研究设计，以935名六、七、八年级学生为研究对象，通过成就测验收集数据。成就测试包括需要比例推理的真实的生活问题，并与长度，周长，面积和体积概念的测量有关。此外，研究人员对其中12名学生进行了任务型访谈，以收集更全面的数据，并支持成绩测试的结果。结果发现，虽然学生大多数都能成功地给出正确的答案，但他们的推理缺乏一个明确的论点之间的直接和间接的比例关系的变量，他们接近的问题的表面特征。
ABSTRACT The purpose of this study was to examine middle school students’ proportional reasoning, solution strategies and difficulties in real life contexts in the domain of geometry and measurement. The underlying reasons of the difficulties were investigated as well. Mixed research design was adopted for the aims of the study by collecting data through an achievement test from 935 sixth, seventh and eighth grade students. The achievement test included real life problems that required proportional reasoning, and were related to the measurement of length, perimeter, area and volume concepts. In addition, task-based interviews were conducted on 12 of these students to collect more comprehensive data and to support the findings of the achievement test. Findings revealed that although students were mostly successful in giving correct answers, their reasoning lacked a clear argument of the direct and indirect proportional relationships between the variables and that they approached the problems by superficial characteristics of the problems.
