The study aimed to identify the degree of use of digital environments based on adaptive learning in developing deep understanding skills among master's students in colleges in the Arab East, and to identify the obstacles to their use, as well as arriving at the requirements for using digital environments based on adaptive learning in developing deep understanding skills among master's students. In the colleges of the Arab East, it also sought to identify the presence of statistically significant differences between the average grades of the sample regarding the degree The use of adaptive learning environments in developing deep understanding skills is attributed to the variables (college, scientific specialization), and the descriptive approach was used in its analytical style, by applying the study tool represented by a questionnaire consisting of (35) items divided into three axes that was applied to a sample of male and female students. The (Master's) stage at the Arab East private colleges reached (296) students, and the study concluded that the degree of use of digital environments based on learning The degree of adaptive learning in developing deep understanding skills among master's students in colleges in the Arab East was moderate, and the obstacles to using digital environments based on adaptive learning in developing deep understanding skills were weak, and the requirements for using digital environments based on adaptive learning in developing deep understanding skills. It came in at a moderate degree, and the study also found that there were statistically significant differences between the average scores of the sample regarding the degree of use of environments Adaptive learning in developing deep understanding skills according to the  variable of specialization .
