The placement teaching system originated in16th century. The teaching mode of one teacher with multiple children can make more children receive education.

In modern kindergartens, primary education is not advocated. Group teaching activities can be controlled within 2 hours a day.

This provision is completely reasonable.

Reason: 1 Collective teaching activities are helpful to children's knowledge cognition.

Two hours a day is an acceptable range for children of this age.

In the rest of the day, there are independent activities and group activities.
