Abstract
This study aims to examine the solution proposals of preservice mathematics teachers regarding students’ incorrect solutions to the expressions 3-2.53= 15-6 and 128:62= 24. The purpose of the study is to identify how teacher candidates approach these error situations, to reveal possible misconceptions related to multiplication and division of exponential expressions, and to explore instructional strategies proposed to correct such errors. In this context, the study seeks to contribute to preventing similar misconceptions from recurring and to guiding teachers who encounter these types of errors in classroom settings. The study was conducted using a qualitative case study design. The study group consisted of thirty-five fourth-year preservice mathematics teachers enrolled at a public university during the fall semester of the 2024–2025 academic year. Data were collected through a written opinion form consisting of two open-ended questions related to errors in multiplication and division of exponential expressions. The collected data were analyzed using content analysis. The findings revealed that preservice teachers most frequently proposed strategies such as explaining exponential expressions through repeated multiplication, using simple examples, and applying factorization. However, it was also observed that some preservice teachers had difficulty in developing effective solution proposals for the given error situations. These findings indicate the importance of strengthening preservice mathematics teachers’ pedagogical content knowledge related to exponential expressions and student misconceptions.
