摘要：The main problem of this study was to build up a new model to assess the Mathematical Power (MP). After defining the dimensions of MP, the measurement tools, used for the interpretation of MP, were determined and applied to 62 students from three classes of a primary school, in accordance with the case study methodology, in order to get the qualitative and quantitative data. The data were analyzed by rubrics through the constant comparative analysis methodology. Thus, a picture was obtained showing the MP levels of 8th grade students.It was determined that, most of the students were not able to reach the expected MP level, especially because of their failures in problem solving, reasoning, communication and making connections. To change this negative picture, some recommendations were presented about teaching materials, structure of standard tests and in-service courses.
