We find that bright children are rarely held back by mixed-ability teaching. 11 , both their knowledge and experience are enriched. We feel that there are many disadvantages 12 . It does not 13 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 people just according to their 14 . 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 15 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 skill. They also learn how to 16 as well as learning how to think, to make decisions, 17 , and to communicate effectively. The pupils learn from each other as well as from the teacher.
Sometimes the pupils work in pairs; sometimes they work on individual 18 , and they can do this at their own speed. They also have some formal class teaching when this is appropriate. We encourage our pupils to use the library, and we teach them 19 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 20 .

Several months ago, Bill Clinton and Tony Blair linked up to proclaim one of science's greatest achievements: decoding the human genome or \February scientists get their first look at the evidence, with the official publication of the human genome sequence in the journals Nature and Science.
The two rival sequencing organizations — the Public Human Genome Project and Celera, the US biotechnology company — have produced scores of scientific papers. Their most striking conclusion is how few genes we have: around 30,000. That is about the same number as a mouse and only twice as many as a fruit fly or a worm. Most scientists had expected to find about 100,000 human genes and some estimates ran to 140,000 genes.
Eric Lander, director of the Whitehead Centre for Genome Research in the US, says: \
Biologists will have to stop thinking of individual genes giving the body instructions to make individual proteins (proteins are the molecules such as hormones and enzymes that control biological processes. Instead, all our DNA —the genome —must be seen as one immensely complex system.
As Craig Venter, president of Celera, puts it, \genes, merely networks that exist at various levels and various connectivities, and at different states of sensitivity to perturbation. The notion that one gene equals one disease, or that one gene produces one key protein, is flying out of the window.\
No one knows how many proteins there are. The answer will be revealed over the next few years by the emerging field of proteomics, successor to genomics. But Dr. Venter estimates that we have 250,000 different proteins — about ten for every gene — to do the essential work in our bodies.
Some experts were saying that the unexpectedly low number of human genes would be good for medicine, since there are fewer genes to understand. But it could work equally well in the opposite direction: the complex interactions between genes may make it harder to cure disease by changing one or two of them, for example through gene therapy. This may explain partly why gene therapy has given disappointing results in clinical trials over the past ten years. The emerging technology of stem cells replacing failing cells with potent new cells may produce better results because the patient is receiving the whole genetic system at once.
