The purpose of this research was to determine the success levels in modeling the multiplication operation in algebraic expressions in the secondary school 7th grade mathematics curriculum, to determine the modeling levels and to offer solutions. Phenomenology design, which is one of the qualitative research methods, was used in the research. The study was conducted with 30 7th grade students studying at a public school. As data collection tools, an achievement test and semi-structured interview form prepared in accordance with the opinion of field and language experts were used. In the achievement test, which was created to determine the level of success in modeling the multiplication process in algebraic expressions, 5 open-ended questions were asked to the students in accordance with the opinions of experts, and interviews were conducted with 6 students who had different levels of learning among the students to whom the achievement test was applied. It is thought that the result of the research will contribute to the literature in order to improve instructional planning and will shed light on future research.
