On the First of December, the joint research project DATAFIED (DATA For and In EDucation) has been officially launched. Together with the GEI, the Helmut Schmidt University Hamburg (HSU), and the DIPF, the effects of the advancing digitisation and the attached datafication in the school education system will be investigated. Datafication, by the means of the school education system, can be perceived in a way that data is collected on all processes of the school system, which simultaneously influences decision-making and opinion-forming processes of various school actors (e.g. education policy, school supervision, school authorities, teachers, or parents).
