Abstract

One of the most effective strategies to enhance student’s geometric understanding in mathematical communication is by giving assignments based on analogy reasoning. Geometric analogical reasoning (GAR) is a reasoning skill used in completing geometry case by applying visual, concept or problem-solving approach. Completion of assignments with GAR increases quality when combined with divergence problems question that required by students to be well communicated. This study aims to analyze differences in student’s mathematical communication on geometric problems with divergence problem model that is reviewed based on GAR type. There was six students were involved in this research. This study was conducted using qualitative approach with observation and in-depth interview as data collection methods. The data was analyzed by followed systematic procedure includes: data reduction, data display, data interpretation, and conclusion. Based on the analysis show that there are three different types of GAR in mathematic students, namely the visual analogy, the analogy of structure or conceptual, and the analogy in the way of completion as well as three different types of communication. The type of communication observed has a pattern that is congruent with the three types of GAR that emerge, namely explanation through images or visuals, through concepts and through the inclusion of examples. Thus, it is suggested, (1) students must be able to make questions in the form of divergence problems. (2) Students must have the ability to communicate divergence problems solutions according to the type of GAR they have.
