摘要：In mathematics,the usage of language seen as an essential component to ensure the attendance of students,and students' need to be able to use the mathematical language efficiently. To acquire mathematical language skills,activities,which students can share their strategies and analyze them,are required. Since not all strategies are of equal value,students need to learn how to analyze others' strategies and intentions to identify their strengths and weaknesses,in other words,to criticize them. From this point,the student should not only express his / her ideas but should be able to talk about the thoughts or strategies of others. It is believed these activities can be useful for improving high-level thinking skills such as critical thinking,reasoning,and association. So it is necessary to investigate whether students are interested in others' ideas and how they express those ideas. From this point,this study aims to examine the fourth-grade students' analysis of the problem solutions of their peers' and express their ideas about these solutions by using mathematical language. This research is a case study. The study group consists of 23 students attending fourth grade in an elementary school in Ordu,Turkey. The data collected through the papers contain the solutions of fourth-grade students outside the study group. A content analysis carried on the data collected from the interviews with the students about sample solutions. According to findings;if the student understands the problem context and solution,he/she can develop a connection between the text and the solution while talking about the situation and can explain this connection by giving cause-effect statements in their talkings. Otherwise,the students could not go beyond describing the given mathematical situation. These results propose it is a critical learning and measurement tool to encourage students to share their thoughts in classrooms. According to the findings,it can be said that strong or weak language usage is also related to the level of comprehension of the problem context. It is believed that the conclusions can contribute to the understanding of the students' strategies and can enhance expressing their ideas through mathematical language. The findings of this study and some questions emerged are valuable for teachers and researchers intending to improve student achievement. As reported in the research results,some of the students described only the situation instead of evaluating the strategy. Mathematical conversations and strategy sharing exercises that teachers can make in their classrooms is an important application for eliminating this situation.
