Abstract

In this study, it was aimed to examine the problems that the pre-service mathematics teachers posed about the square root expressions. 35 pre-service teachers studying in the third grade of the middle school mathematics teaching department of a state university participated in this study in which the case study method was used. Each pre-service teacher was asked to pose 2 free problems related to the square root expressions. The collected data were analyzed according to the framework created by the researcher in line with the literature. Accordingly, the problems that the pre-service mathematics teachers posed were examined in terms of mathematically, data quality, grammar and expression, instructions and amount of data in the problems, solvability and overall assessment (availability). As a result, it was seen that pre-service teachers generally set up problems involving daily life, more than half of the problems they set up were solvable, but there were also problems that could not be solved due to logic errors, conceptual errors and lack of mathematical instructions.  In addition, although there were errors in terms of language and expression in the problems, the majority of the pre-service teachers used language and expression at an adequate level.
分析职前数学教师提出的平方根表达式问题质量的研究
本研究旨在探讨职前数学教师对平方根表达式提出的问题。35 名就读于某州立大学中学数学教学部三年级的职前教师参与了本研究,本研究采用了案例研究法。每位职前教师被要求自由提出 2 个与平方根表达式有关的问题。研究人员根据文献建立的框架对收集到的数据进行了分析。因此,从数学、数据质量、语法和表达、问题中的说明和数据量、可解决性和整体评估(可用性)等方面对职前数学教师提出的问题进行了研究。结果显示,职前数学教师所提出的问题一般都涉及日常生活,超过半数的问题是可以解决的,但也有因逻辑错误、概念错误和缺乏数学指导而无法解决的问题。 此外,虽然在问题的语言和表达方面存在错误,但大多数职前教师的语言和表达能力都达到了一定的水平。
