<p>Mathematical modeling has come into prominence during the last few decades in many</p> <p>countries’ mathematics teaching curricula. It combines real life situations with</p> <p>mathematical context. Although evaluating students’ mathematical modeling</p> <p>performances with a unique Likert type instrument is questionable, having an instrument</p> <p>about their self-efficacy beliefs in mathematical modeling may help to comment about</p> <p>their ideas related to their competencies in mathematical modeling. The purpose of this</p> <p>study is to develop a reliable and valid measurement scale to determine mathematical</p> <p>modeling self-efficacy of mathematics teacher candidates. For this purpose, the draft and</p> <p>final form of the scale were applied to a total of 562 pre-service elementary mathematics</p> <p>teachers from various public universities in Turkey. The findings of study revealed that</p> <p>the scale is unidimensional according to the results of exploratory factor analysis. The</p> <p>unidimensionality of the scale was validated by confirmatory factor analysis. The</p> <p>reliability of mathematical modeling self-efficacy scale was very high (.97). Finally, it</p> <p>was found that this scale is an appropriate measurement tool to evaluate students’ self-<br /> efficacy beliefs on their mathematical modeling competencies. Some suggestions related</p> <p>to the scale and for further studies were given at the end.</p>
