Abstract:

In this study, a measurement tool was developed to measure the scientific thinking dispositions of 48-72 months old children. The study group of the research consisted of 489 (255 girls, 234 boys) children attending pre-school education institutions. Various analyzes were carried out in order to provide evidence for the reliability and validity of the "Scale for Evaluating the Scientific Thinking Disposition in the Early Years". Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were performed to provide evidence for the construct validity of the scale. As a result of the analysis, a scale structure with 6 sub-factors and 25 items emerged. The Cronbach Alpha reliability coefficient of the whole scale was found to be 0.898. The internal consistency coefficients for the sub-factors are as follows: 0.893 for the 1st factor, 0.890 for the second factor, 0.906 for the third factor, 0.884 for the fourth factor, 0.869 for the fifth factor, and 0.951 for the sixth factor. The reliability coefficients of the sub-factors ranged from 0.890 to 0.951. When the reliability analysis results obtained from the scale are examined, it can be said that it is a valid and reliable measurement tool in terms of both general and sub-factors.
