A questionnaire prepared specifically for the purpose of this study was used, and the validity and reliability of the instrument were confirmed. The study was applied in the first semester of the scholastic year 2021/2022. The results showed that the level of availability of twenty-first-century skills in the developed science textbooks (Collins) was in intermediate with an average of 3.48. In previous science textbooks, it was also intermediate with an average of 2.70. The results also indicated that there are statistically significant differences in teachers' responses to the availability of skills in the twenty-first century in advanced science textbooks (Collins) and previous textbooks in favour of the developed science textbooks (Collins).
