Chinese elementary and middle school students spent an average of 2.82 hours a day doing homework during the last 3 years, said a recent report issued by Afanti, a smart education platform.

The report sampled data from nearly 100 million registered users of its online platform and offline users from nearly 100 physical stores.

Though the figure, 2.82 hours, experienced a slight drop from the previous 3.03 hours, it is still three times the world average.

The report said 91.2% of the parents have accompanied their children when doing the homework at least once, and 78% of them have made it into a daily routine.

A total of 75.79% of Chinese families have experienced conflict over doing homework, which led to a decrease of happiness among many of the parents.

In addition, homework has also become a burden for teachers. According to the report, teachers have to spend 40.37% of their time correcting homework.

However, the report predicted that artificial intelligence might be a solution, noting the development of homework correction robots as an example.
