In tradition (传统的) education, the teacher may feel that the students are not very grown up. Usually, teachers are older than students, and teachers feel that students are young and do not know much about the world. The teachers feel that they must tell the students what to do most of the time, and that they must also make the students study specific (特殊的) things. In open education, the teacher’s methods are very different. These teachers feel that the students are human beings (人) first, and students second. They expect the students to be responsible for the things that they do, just as adults are. A student’s ideas and feelings are just as important as the teacher’s. The teacher allows the students to decide what they want to do, and does not make them study what they do not want to. The teacher lets them decide what to study and how much to study. It’s very important for the teacher to show how he or she feels about students.
