We find that bright children are rarely held back by mixed ability teaching. On the contrary, both their knowledge and experience are enriched. We feel that there are many disadvantages in streaming(把……按能力分班) pupils. It does not take into account the fact that children develop at different rates. It can have a bad effect on both the bright and the not-so-bright child. After all，it can be quite discouraging to be at the bottom of the top grade！

Besides, it is rather unreal to grade pupils just according to their intellectual(智力的) ability. This is only one aspect of their total personality. We are concerned to develop the abilities of all our pupils to the full, not just their academic ability. We also value personal qualities and social skills, and we find that mixed-ability teaching contributes to all these aspects of learning.

In our classrooms, we work in various ways. The pupils often work in groups: this gives them the opportunity to learn to co-operate, to share, and to develop leadership skills. They also learn how to deal with personal problems as well as learning how to think, to make decisions, to analyze and evaluate, and to communicate effectively in order to have the ability to become leaders. The pupils learn from each other as well as from the teacher.

Sometimes the pupils work in pairs；sometimes they work on individual tasks , and they can do this at their own speed. They also have some formal class teaching when this is suitable. We encourage our pupils to use the library, and we teach them the skills they need in order to do this efficiently. An advanced pupil can do advanced work：it does not matter what age the child is. We expect our pupils to do their best, not their least, and we give them every encouragement to attain this goal.
