Education is another area of social life in which information technology is changing the way we communicate.

For children over the age of 10 daily attendance at schools is not compulsory. Yet, some of the older children attend school only once or twice weekly to get tutorial support or instruction from teachers. For the most part, students are encouraged to work online from home. Students must complete a minimum number of study hours per year; however, they may do this by studying at home at times that suit their family schedules. They can log on early or late during the day and even join live classes. In order to ensure that each student is learning adequately, a computer software will automatically monitor the number of hours a week each student spends studying online as well as that student's learning materials and assessment activities. Reports will be available for parents and teachers. The software can then identify the best learning activities and conditions for each individual student and generate similar activities. It can also identify areas of weak achievement and produce special programs adjusted to the students' needs.
