Good afternoon! It’s my pleasure to briefly introduce my school life regarding two aspects, independent learning and cooperative learning.
Independent learning is a basic principle of my school education. At one level it encourages us to work out plans and arrange our timetable, in which case we improve our independent thinking and management skills. On another level, it presents us with a block of work in which we are developing strategies.
Meanwhile, we are making great attempt to create a cooperative-learning environment, where we are encouraged to work in groups. Within group work, we are guided to voice our individual opinions, listen to each other and respect each other.
