A primary school teacher in Sydney's west has spoken of how radicalised Muslim boys wore ISIS shirts to class and circled around her menacingly reciting the Koran.

The woman, known by the pseudonym of Mrs A, told former federal Labor leader Mark Latham about the horror of being intimidated by students aged between 10 and 13.

'I had students coming into class flying flags from overseas, be it the Syrian flag and possibly the ISIS flag. It looked to me like the ISIS flag,' she told the Mark Latham Outsiders program.

'There was one occasion where a couple of boys had come to school wearing T-shirts that appeared to have the ISIS flag wording.'

On another occasion, a group of students circled her against a wall and began reciting the Koran, she claimed.

'That was quite scary and it wasn’t only scary for me but it was also quite intimidating for the other students,' she said.

'The other students were quite frightened, non-Islamic and Islamic students.’

The incidents, involving students in Years 5 and 6, occurred in 2014 as ISIS gained territory in Iraq and Syria.

The teacher, who has taught in the same area for the past decade, also endured students making threats to her with throat slitting gestures.

'Sometimes they would even make comments, "I can do this to you",' she said, demonstrating the intimidating finger movement.

She added that some students would 'constantly make threats to behead' her in class.

A spokesman for the Department of Education confirmed to Daily Mail Australia on Thursday the incidents she described had taken place.

The teacher said the students' behaviour worsened after they had watched the ABC's children's current affairs program Behind The News.

'We would watch some programs at school, one of them being the ABC Behind The News program, which tended to have a bit of a sympathetic voice towards ISIS,' she said.

'If there was a segment about ISIS, or something to do with Islam, their behaviour seemed to have heightened. So I actually stopped watching it altogether.'

However, an ABC spokesman denounced the claim about Behind The News.

'Any such claim would be nonsensical and offensive,' he told Daily Mail Australia.
