Headteachers have declared they have no confidence in the Government's education policies at the National Association of Head Teachers union conference in Birmingham.
Education Secretary Michael Gove met some of the teachers at a question and answer session - where he faced a barrage of hostile questions.
Mr Gove refused to apologise for what he said was "trying to raise standards in classrooms".
ITV News correspondent Romilly Weeks reports from Birmingham:
Responding to a union leader's description of him as a "fanatical personal trainer," Mr Gove said: "You'd have to be a fanatical personal trainer to want to take me on".
He received no applause when he was introduced at a question and answer session at the National Association of Head Teachers' conference in Birmingham.
Education Secretary Michael Gove got the first round of applause of his address to the NAHT conference when he said he is "having second thoughts" about his plans for overhauling the teaching of history of schools.
He said he still wanted there to be an emphasis on "chronology" and "understanding narrative of this country," but that he did not want only British history to be taught, as some believe.

We need to raise standards so we have an education system that is on a par with the world's best.
Our academies programme is turning around hundreds of underperforming schools, we are introducing a world class curriculum and our reforms to exams will create qualifications that will keep pace with the demands of universities and employers. Surely this is something the NAHT should be supporting.
We will not stand by when schools are failing our children. Sponsored academies are turning around hundreds of underperforming schools and ensuring pupils are given every chance to fulfil their potential.
Headteachers have declared they have no confidence in the Government's education policies at the NAHT union conference in Birmingham.
President of the National Association of Head Teachers, Bernadette Hunter told the union's conference in Birmingham that current Government policies on education are "damaging schools" and negatively affecting pupils' lives.
Kenny Frederick, a headteacher and member of the NAHT executive, has accused the Education Secretary Michael Gove of wanting to "bring us back to 1950s".
Speaking on the BBC's Radio 5 Live, she said that Mr Gove has not listened to teachers and that his plan was destined to "fall flat on its face".
Mr Gove is expected to receive an angry reception when he speaks at the NAHT conference in Birmingham this afternoon.
Bernadette Hunter, president of the National Association of Head Teachers is expected to tell delegates at the NAHT's annual conference in Birmingham today that many schools "have lost their sense of humour, buried under piles of data and spread sheets".

Perhaps you don't always feel strong but every day you have to deal with a torrent of initiatives and changes which rather resembles wrestling with an octopus. And you do it because of the moral imperative of school leadership - learners.
I know we are tired of constant, ideologically-driven change. We always seem to be saying that this is the worst we have ever known it but this time it is undeniably the truth.
We seem to have a secretary of state for Education who doesn't seem to be for education at all.
She warned the entire education system was "being dismantled before our eyes and fragmentation and division are everywhere".
There was a "continual denigration of our professionalism and a worrying creeping privatisation of education," she said.
Schools are losing their sense of humour under piles of data and spreadsheets as headteachers are forced to "wrestle with an octopus" of government initiatives and reforms, a union leader will warn today.
Heads are becoming tired of constant change to the education system, and believe it is being dismantled before their eyes, according to Bernadette Hunter, president of the National Association of Head Teachers (NAHT).
In a strongly-worded attack, Ms Hunter will say she believes that Education Secretary Michael Gove is not a champion of education, and liken the minister to a "fanatical personal trainer" urging headteachers to go "faster, faster, higher and higher".
