Dear Wang Hao,

I was pleased to receive your letter. I admire your spirit of exploration. Here are the replies to your questions.

We are attempting Research-oriented Learning in order to challenge the traditional teacher-centered teaching method, where teachers do all talking while students do nothing but listen. On top of being boring and inefficient, this method leads to a loss of creativity in us.

Research-oriented Learning usually consists of four steps. First, set up research groups and determine a research project, which is connected with what we are studying. Second, collect and refer to relevant materials and data. Third, discuss in groups and everyone expresses their opinions to the full. Finally, exchange our reports about the project in class.

Research-oriented Learning has brought fresh air into our classrooms. It has motivated every student greatly, and helps to develop our critical thinking and competence in innovation.

Of course, we have met with many difficulties. The biggest trouble facing us now is that, as completing a project often takes much time, many parents fear that this learning may affect their children’s college entrance examination results.

With best wishes.

Yours,

Li Ming
