Christine Blower, leader of the National Union of Teachers has accused Education Secretary Michael Gove of "messing with the national curriculum" and challenged him to visit more state schools.
"We would like him to walk around a lot more state schools, not just free schools and academies that are state funded. He would see there are plenty places doing after school clubs, sport and drama," said Blower.
"It would also be a good idea if Michael Gove stopped messing about with national curriculum and allowed the kind of curriculum freedoms that exists in some schools to exist in all schools," she said.
Blower added that Gove was "absolutely wrong" on his suggestion that more testing in schools is needed and claimed his calls for more power and freedom for teachers' to discipline students implied that state schools are "chaotic".
Only 8% of parents support the education secretary's reforms and think they are good for their children, the general secretary of the National Teacher's Union (NUT) said.
Christine Blower made it clear no one - teachers and parents - wanted to resort to a strike, but industrial action was necessary if a pay system which was "fair" to teachers "everywhere" was implemented.
Thousands of pupils across England will miss a day of school as their teachers go on strike in a row over pay, pensions and conditions, their unions have announced.
The National Union of Teachers (NUT) and NASUWT say members are fed up with Government reforms which will cut deeper into salaries and force staff to work longer, while pensions pay out less.
Pupils in four regions of England - the North East and Cumbria, the South West, South East and London - will be affected, as members of two of England's biggest teaching unions take part in the second day of walkouts this term.
NASUWT general secretary Chris Keates said the "overwhelming majority" of teachers in these regions would be on strike and blamed education secretary Michael Gove for the industrial action.
"It is the failure and unreasonableness of the Secretary of State, who day-in-day-out is disrupting the education of children and young people through his attacks on the teaching profession."
