Abstract
The purpose of this Study was to uncover the inclusion of the 21st century skills in the content of Physics Textbook for tenth grad developed for the Year 2020/2021 in Jordan. To achieve the aims of the study, analytical descriptive method (the technique of content analysis) was used. The sample of the study was its community, and it included all the topics of the physics textbook for the tenth grad. The instrument of the study was designed in light of the 21st century skills that proposed to be in the physics textbook for the tenth grade. The instrument contains three domains: Learning and Innovation, Information, Media and Technology, and Life and Career. The results of the study revealed that the degree of the inclusion of 21st century skills in the content of textbooks was ranked as medium. In light of these results, the study recommended the need to reconsider the content of the physics textbook for the tenth grade to raise the degree of its inclusion of twenty-first century skills.
