Validity and reliability of the study were examined, where the reliability coefficient of Holsti was (86%), and frequencies and percentages were used for data analysis. Results showed that the inclusion level of 21stcentury skills in physics (1) textbook ranged from high to low. The inclusion level of learning and innovation domain was high with (92. 38%), digital culture domain was low with (4.44%), and profession and life domain was the lowest with (3. 18%). Accordingly, recommendations were proposed, such as designing learning activities and integrating them in physics (1) textbook to develop 21st century skills. (Published abstract)
