were difficult, 25 items (0,41-0,59) were moderately difficult, 33 items (0,62-0,80) were easy, and 21
items (0,82-0,95) are quite easy. The findings related to the item discrimination index indicated that

to the items correctly. The reliability of the measurement instrument was found as 0,89. It can be
