This content analysis is composed of a card consisting of (43) criteria distributed over (8) fields, after approving its validity and reliability. The sample of the study consisted of (56) Islamic studies teachers in Al Batinah North Governorate who were chosen using stratified random sampling. The study showed the following results: 1.
