@amoroso I, like many others working in technical fields, whether they realise it or not, benefited tremendously from the ideas of Seymour Papert getting into the traditional education system via logo and computer-assisted learning. The availability of information on the internet has done a tremendous amount to democratise access to learning, which aligns with Papert's constructionist ideas. This paper criticises Papert, damns his groundbreaking work (for its time) with faint praise and does not point to anything superior in the standard public education system that the author contrasts it with. I'm old enough to remember how dependent students were on the quality of their teachers and library resources before the internet. This dependency ensured inequality of educational outcomes for generations before. Papert did not get everything right for everyone, and I can accept that he overestimated how many students would benefit from learning maths through logo, but I think he got a lot of things right educationally, at least for an important subset of students who were ill-served by the traditional education system. Another thing not mentioned in the paper was that schools tried to implement his ideas without the people implementing them having a good idea of what those ideas were trying to achieve.
