For the last three months, the schoolgirls have been made to stand in the assembly hall while other pupils from other levels sat during reading time.
They did that for 15 minutes each day, as they waited for classes to begin. Their offence: Talking noisily during reading time.
These are 29 Primary 2 pupils from top school Raffles Girls' Primary. Their punishment came to light after a parent of one of the girls found out about it and complained to the Education Ministry last Friday, hoping that both the ministry and the school would give parents "a reasonable explanation on the matter".
He asked if the punishment was excessive and questioned why it had, in his wife's words, "no expiry date". She said: "They are still young and all they know is that the teacher is the authority and they were just following her instructions.
"No one asked how long the teacher needed to mete out the punishment." The school has since stopped the punishment. The school principal Yue Yoke Mun said in an e-mail reply yesterday: "The school believes in nurturing our students with good values and we appreciate parents' feedback.
"This measure to instil better selfmanagement and discipline among the students has already been stopped."
