Abstract: The purpose of this study was to comparatively investigate the mathematical communication competency of mathematically gifted and non-gifted eighth-grade students. In this qualitative research, the multiple case study method was used. The participants consisted of a total of 10 eighth-grade students, comprising five mathematically gifted and five non-gifted students. The Mathematical Communication Competency Measurement Tool and Clinical Interview Form were used as data collection tools. The research data obtained with the Mathematical Communication Competency Measurement Tool were analyzed quantitatively by considering the levels of mathematical communication competency, whereas deductive analysis was performed on the data collected through the clinical interviews. As a result of the study, similarities were observed in the way mathematically gifted and non-gifted students employed mathematical communication competency in the process of solving relatively low-level (level 1) problems. However, for relatively high level (levels 2 and 3) problems, gifted students differed in terms of revealing the purpose of the problem, explaining a mathematical result, and presenting verbal and/or written justification.
