| Representations are very powerful tools to explain mathematical reasoning processes and to understand relationship between any mathematical concepts in problem solving processes (Goldin, 1998; NCTM, 2000). The purpose of this study is to find out a possible relationship between eleventh grade students’ representations and geometric reasoning in the geometric word problem solving process related with polygons. To do this, a qualitative design which is case study was used and three 11th Grade Anatolian High Schools students were determined as participants via results of geometry achievement exam prepared by researcher, average of written examinations which were belong to first semester, and geometry teacher’s opinions about students. The data were collected using by think aloud method, two geometric word problems focused on polygons, and unstructured interviews. Each student practiced the think aloud method before solving two geometric word problems. After working on each problem separately, students were interviewed about fifteen minutes. These data were analyzed using the withinacase techniques.The findings of this study showed that when students misunderstood a geometric concept, they produced useless representations to solve problems. In addition, because of the uneasy nature of word problems, participants had some difficulties in geometric reasoning process. As a result of misunderstandings about geometric word problems, there was not any interaction between internal and external representations of participants, which revealed students’ rote learning related to geometric concepts. There is no doubt to … |
