Two schoolboys were allegedly disciplined after refusing to kneel down and "pray to Allah" during a religious education lesson.
It was claimed that the boys, from a year seven class of 11 and 12-year-olds, were given detention after refusing to take part in a practical demonstration of how Allah is worshipped.
Yesterday parents accused the school of breaching their human rights by forcing them to take part in the exercise.
One, Sharon Luinen, said: "This isn't right, it's taking things too far. I understand that they have to learn about other religions. I can live with that but it is taking it a step too far to be punished because they wouldn't join in Muslim prayer.
"Making them pray to Allah, who isn't who they worship, is wrong and what got me is that they were told they were being disrespectful."
Another parent Karen Williams, 38, whose 12-year-old daughter is a classmate of the boys, said: "I am absolutely furious my daughter was made to take part in it and I don't find it acceptable.
"The teacher had gone into the class and made them watch a short film and then said 'we are now going out to pray to Allah'.
"Then two boys got detention and all the other children missed their refreshments' break."
She added: "Not only was it forced upon them, my daughter was told off for not doing it right.
"They'd never done it before and they were supposed to do it in another language."
She said the pupils were asked if they had water on them, and when one girl produced a bottle, the teacher began washing her feet with it.
Her husband Keith, 44, a painter and decorator, said: "The school is wonderful but this one teacher has made a major mistake. It seems to be happening throughout society. People think they can ride roughshod over our beliefs and the way we live."
The alleged incident, at the Alsager school, one of Cheshire's top performing schools, happened on Tuesday afternoon. The teacher, Alison Phillips, the school's subject leader in RE, is understood to be staying away from the school until the furore dies down, although she has not been suspended.
She is said to have got prayer mats out of the cupboard and also asked children to wear Islamic headdresses.
Deputy headmaster Keith Plant said: "I have spoken to the teacher and she has articulately given me her version of events."
Sources at the school said the incident could have been down to Miss Phillips instigating a role play and not properly briefing the pupils, all aged around 12, what she was doing.
A couple of points stand to be made here. The first is that compelling children to engage in or to simulate Islamic rituals, without asking the consent of their parents, and treating them as miscreants when they refuse to do so, is totally unacceptable. As many other bloggers have already pointed out, it is rather difficult to imagine that any teacher would dare to compel Muslim children to engage in acts of Christian worship against their will.
It's true that British state schools are obliged to hold acts of collective worship of a Christian character. But this simply reflects the fact that Christianity is, and has for 1,500 years been, the majority religion of our country, and is a fundamental building block of our native culture. More pertinently, parents have the right to withdraw their child from all such collective acts of worship, should they feel strongly enough about it. From the details of the incident at Alsager School, it would seem that Ms Phillips' actions went, at the least, against the spirit of respect for parental choice which is the basis for this exemption.
More generally, I am inclined to wonder why the children were being expected to perform or simulate Islamic acts of worship anyway. After all, in order to learn about Islam one does not actually need to engage in such acts. Presumably, this is simply another instance of the ridiculous "make learning fun" approach, under which children spend their time imagining what it might be like to be a Muslim, or "a Spanish sailor about to embark in the Spanish Armada", or, as occurred in my own schooldays, a fellow passenger of Rosa Parks', or an Egyptian slave labourer working on the pyramids. All very enjoyable no doubt, and easy on the teacher too (washing one's feet and distributing prayer mats is probably rather less challenging than explaining the finer points of Sharia law), but not something which leaves the pupil with any actual knowledge of the subject, and not something which really has a place in any class other than Drama.
Finally, I have to ask: if Ms Phillips really wanted to show the children how Muslims pray, should she not have taken herself and the girls in the class off to a separate room, to ensure that lewd thoughts did not distract the boys from their devotions? That is, after all, what would have happened in a real mosque. Or do RE teachers commonly write Islam's less palatable aspects out of the script?
