The study was conducted using a qualitative method, specifically a case study design, and was carried out with a middle school mathematics teacher selected through purposive sampling. Data were collected using the Problem Posing Content Knowledge Test (PPCKT). The participating teacher was asked to create problems suitable for the given operations, and these problems were evaluated and analyzed according to the scoring guidelines determined by Örnek (2020), which include the dimensions of "meaningfulness," "solvability," "language," and "realism." The analyses revealed that the teacher created problems that were “partially adequate” in terms of language, realistic stories, and problems where the data were meaningful and solvable in a formal sense.</p> Kübra SEFEROĞLU KAYNAK Yasin SOYLU Copyright (c) 2024 Online Journal of Mathematics, Science and Technology Education https://creativecommons.org/licenses/by-nc-nd/4.0 2024-12-01 2024-12-01 5 1
