Why al Thuraya did not teaching online ?

because it is Less Direct Contact

Online classes don't offer the same immediate and regular access to instructors and classmates as traditional face-to-face classes. The communication typically takes place through e-mail and in virtual discussion forums. While this can aid in learning technology, it negatively impacts a student's ability to interact with professors, ask questions and get immediate help. It also takes away from some of the social and team-building that occurs informally in college classrooms.

Time Commitment

Students sometimes misconstrue that online classes require less time and effort than traditional courses. The Montgomery College Online Student Success Center noted that active and self-disciplined learners typically succeed. Students who struggle with traditional course rigor often have difficulty with the time commitment required for online classwork. You normally have to schedule time each day to read assignments and complete quizzes and tests that you would take in class in a traditional setting. Online students also have to engage in class discussions and complete assignments, papers and projects. Team activities may also add to the time commitment in some classes, as students must often communicate with peers electronically and collaborate on work.

Less Accountability

Online students can't rely on as much instructor and peer feedback and accountability as traditional courses sometimes offer. Instructors often update grades through virtual grade books and don't have as much opportunity for regular informal feedback before and after classes. Additionally, students don't have regular contact with class peers, who can offer assignment reminders and encouragement to complete projects and assignments. This also applies to team activities since you don't have direct interaction with teammates pushing you to complete your responsibilities.

Higher Dropout Rate

Tangibly, the most negative effect of online classes is a higher rate of class failure and dropouts. A study revealed in July 2011 by the Columbia University Community College Research Center indicated that Washington community college students were more likely to drop online classes than traditional ones. Course completion for traditional courses was 90 percent, and for online classes, it was 82 percent. Additionally, students in the study who took online courses were less likely to complete a degree or transfer to another college. Students studied in 2004 who took at least one fall online class were 34 percent likely to drop out after one year compared to 26 percent who only took face-to-face classes.
