Abstract

The purpose of this research was to adapted the scale for Critical Thinking Disposition (EMI) which was developed by Ricketss and Rudd (2005) into Turkish. 1264 first grade high school students in Ankara participated in the study in academic year of 2011-2012. EMI is a five-point Likert scale consisting of 26 subject items. The correlations between the two languages which were obtained from the group’s scores of the English and Turkish forms were evaluated, thus determining the language equivalency of the scale. Exploratory and confirmatory factor analyses were conducted in order to obtain evidences regarding the structural validity of the scale. The internal consistency coefficients of each sub-dimension of the scale were calculated to determine the reliability analysis of EMI. When the Cronbach’s-alpha coefficients of EMI and its sub-dimensions were investigated, the coefficient values were determined as high. The internal consistency coefficients have similar values to those of the original form, which was indicated in the guidebook of the scale. The results therefore indicate that this scale is highly reliable. The test–retest reliability of the scale was also investigated. For this aim, two trials were conducted, and the scores were analyzed using the Pearson product-moment correlation coefficient method. A positive and highly significant correlation was found between the scores, thereby indicating that the test–retest reliability is sufficient.
