A teacher in Wales is described by his head as 'inspirational',  with classroom skills which are second to none. Yet he is on a disciplinary procedure because of weak data collection. The World Bank is funding educational data collection systems across the global South. Education International is taking part in the Pearson chaired Global Metrics Taskforce. What connects all these facts? Teachers all over the globe are being turned, almost without realising it, into data collectors to feed the ever-open maw of trans-national corporations.

I am indebted to an excellent US for crystallising this idea and for introducing me to the excitable Knewton spokesperson above, rhapsodising about education, 'the fourth biggest industry in the world'. He can hardly contain himself as he tells us that his data will soon cover hundreds of millions of children and will be used to create on-line learning material, fashioned to each child, to the extent that her tablet will even be able to tell her she must eat scrambled eggs for breakfast.

It is bad enough that teachers are rapidly becoming unpaid labourers for corporations. It is worse that they are being bullied into doing so by performance related pay and the threat of censure or the sack if they fail. Worst of all is that the learning relationship of teacher and children is set at nothing, teachers become facilitators of online content delivery and children are reduced to binary codes on a spread-sheet. Child-centred education has become a term of abuse and the concept of critical education is purloined by the 'reformers' and emptied of meaning.

This dehumanisation of teaching and learning is happening all the way from kindergarten to secondary and it's global. The only spaces where it is missing are in the attended by the children of those same – the trainee masters and mistresses of the universe.

As teachers, we have no choice but to put an end to this madness. In taking strike action to defend education, we are making the first steps towards reclaiming our profession from the bean-counters and the plutocrats. As points out, when we strike 'power relations are reversed.' Of course striking is not enough. We have to involve communities, develop a vision of education together and stand with them when they fight anti-education policies like school closures, privatisation, testing and cuts.

Mr Knewton spokesperson on the video, says interestingly of the students, 'they kind of look like fleas' and 'we literally know everything about (them)'. But children are neither fleas nor a collection of data but young humans, who urgently need our help to question the world controlled by the Knewtons, the Gateses and the Pearsons, so that they can build a better one. As our Latin American colleagues say, 'El Maestro Luchando tambien esta Ensenando!'*  Bring on the strikes!
