     SOUTHPORT, ENGLAND-A British teaching union famous for strange ideas has supported

proposal to employ dogs as classroom assistants.

     At the annual conference of the Professional Association of Teachers in Southport, northwest

of England, one person suggested properly trained dogs be able to keep order in primary schools.

They can round up lost children and protect those who experience unfortunate "accidents". Wendy

Dyble, a Shetland Islands woman who teaches children up to age seven, made it clear to her fellow

friends that she was not  "barking mad". They obviously believed her, supporting her idea by 16

votes to 13, with a total of 63 abstentions (弃权).

     She said big dogs could help round up children, keep  them in line, lick up the milk they spill on

the floor and provide the extra eyes that a teacher needs to keep order."A big dog would also be

helpful in breaking up fights and looking for lost property, like gym shoes or dolls, " Dyble said at

the conference."The dog will also be useful in sniffing out smells that children do not own up to, "

she added."It would be nice for the teacher not to have to go round sniffing each child to find the

culprit (犯错的人). "

     The idea was greeted by the Dog Defense League but less so by bigger teaching unions.A

spokesman for Education Secretary David Blunkett, who is blind, said his guide dog was always

popular with pupils when he visited schools.The Professional Association of Teachers, with around

35,000 members, is the smallest teaching union in Britain.It has an honour for occasional strange

ideas.

     Earlier this week, its annual conference here suggested stopping exams because they lead to stress

and introducing selection at the age of 12 based on physical coordination and manual skill in the use

of hand.
