Gegashman over nefaste propaganda voor constructivisme in de pedagogische faculteiten en de lerarenopleidingen: : "Universities and teacher training materials instruct teachers that constructivist teaching practices are more effective, even though the evidence does not really support this. Consultants, school leaders and Dan Meyer himself are all resources that teachers could be expected to consult if they want to improve their practice and they will get a broadly... similar message from each. Where could a teacher even find out about explicit instruction and its effectiveness? Well, I am trying to do my bit in a small way but it hardly compares.
The sadness is that this means that teachers often miss out on training in how to make their default explicit instruction much more effective!" Commentaar; jammer genoeg is dit ook in Vlaanderen al te vaak het geval! Onderwijskrant was wel de eerste die al vanaf 1989 het constructivisme - ook binnen de wiskunde à la Freudenthal Instituut- ter discussie stelde..
