He filed several reports and his 7th submission focused on his experiences in Europe.[22] Filed in 1844, the report contains no reference to Prussian factories nor mention of concepts like efficiency, trained workers, or docile children. While this alone isn't sufficient to refute claims about a factory model mentality informing the development of American schools, it does challenge claims by authors like Taylor Gatto that Mann was eager to replicate a model of education that would train children to work in factories. Likewise, the final report by the National Education Association's Committee of Ten makes no reference to factory skills or to modeling schools after factories[23], a claim that is often found in books that advocate a dramatic change to American public education (e.g., Most Likely to Succeed (2015), by Tony Wagner and Ted Dintersmith).
