     There are some very good things about open education. This way of teaching allows the students to

grow as people, and to develop their own interests in many subjects. Open education allows students to

be responsible for their own education, as they are responsible for what they do in life. Some students do

badly in a traditional classroom. The open classroom may allow them to enjoy learning. Some students

will be happier in an open education school. They will not have to worry about grades or rules. For

students who worry about these things a lot, it is a good idea to be in an open classroom.
