Title Of Article :
Investigating Middle School Mathematics Teachers’ Problem Posing Ability in the Context of Subtraction Operation with Fractions
Abstract :
In this study, it was aimed to determine the errors in the problems posed by middle school mathematics teachers for the subtraction operation with fractions and their opinions about these errors. The study was conducted with seven middle school mathematics teachers working in the city center of Erzurum province. The Problem Posing Test prepared for subtraction operations with fractions and the video records of the focus group interviews used as data collection tools. Eight types of errors were determined in the problems posed. The most frequent error types made by middle school mathematics teachers are as follows: expressing the fractions over the different wholes, logical errors and confusion about units. Additionally middle school mathematics teachers made different errors in explaining the errors.
