In recent years, developments in the field of computerscience, which are in parallel with technology, have led to an increase in theimportance of solving problems with the help of computers. It is also worthmentioning that this skill, which is defined as computational thinking, hasbeen an issue about how to be taught and evaluated. In this context, the aim ofthis study is to develop a self-efficacy perception scale for the computationalthinking skill. As a result of the exploratory factor analyzes made, it wasseen that the scale includes 39 items with five-factors. Additionally, withconfirmatory factor analysis which was carried out for confirmation of themodel, 3 items were omitted from the scale and the last structure of the form,with 36 items, was presented. The corrected item-total correlations wereranged between 0.632 and 0.386, whereas the Cronbach Alpha coefficients werebetween 0.762 and 0.930. Also, t-tests for the item average means of the bottomand top 27% of the groups were presented significant differences between thosegroups.
