Many schools have started projects to make changes to their school grounds in order to make better use of them. The projects have achieved good results. Some schools have reduced heat, some have got more play space, and others have helped create different learning experiences.

The most common practice of the schools is planting more trees around the playground. Trees provide cooler spaces in summer. They also bring birds and insects. Students, therefore, would like to go to the playground more often. And they become more connected to nature. Some schools even set up reading areas under these trees. Students can listen to birds singing while reading there.

   ▲    For example, they turn some of the school grounds into vegetable fields or fruit gardens. The students work in teams and learn how to grow vegetables or fruits. In this way, they get hands-on learning experience. At harvest (收获) time, they share what they get from the fields and gardens, and they also harvest the joy of labor and cooperation.

These reshaping projects make school grounds more popular with students. The reason behind the success is that students are included. After all, they are the users of the grounds. In many cases, designers first survey the students for their ideas. Then they draw up several designs for the students to vote on. When the project is completed, the students are invited to feed back on it so that it can be further improved in the future.
