Abstract:

This research aims to develop a lateral thinking disposition (LATD) scale. The survey method was used throughout the study. In practice, it was studied with 908 students. According to the factor analyses results, KMO value of LATD scale has been found to be 0.794 and the value of Barlett test has been found to be 1585.363 (Sd= 36, p=0.000). LATD scale is a unidimensional scale which explains 46.637% of the total variance. The analysis results of LATD scale is seen to change between 0.41-0.70 of factor loading and between 0.474-0.668 of item-total correlations. It was found out that test-retest correlation was 0.771 and correlation coefficient between two half- points was 0.685. Cronbach Alpha Coefficient of LATD scale has been found to be 0.754. The scale consists of 9 items. According to these results, the scale can be claimed to be valid and reliable. Having proved to be valid and reliable, the LATD scale has gone through confirmatory factor analysis with the help of AMOS program (Chi-square = 6,744, Sd = 16, GFI = 0.998, CFI = 1.000, RMSEA = 0.000). According to these results, the scale is found to be appropriate to be applied to the faculty of education students. Key words: Lateral thinking, lateral thinking disposition, validity, reliability, scale development.
