 This is too generic, all constructivist educational software since Papert and Kay would be included. What's new? What's different now? Do you have anything to say about why the older proposals didn't succeed?

+**---HF**: I don't subscribe to the idea of constructivism, it is most of the time ineffective. Read my article [Dynabook and its learning models](https://gnu-drgeo.blogspot.com/2018/07/the-dynabook-and-its-learning-models.html).
+ To be honest I am neutral to the teaching method, all approaches should be equally accessible. I prefer to think of dynamic media inserted in a _traditional notebook_. It will encourage both reading and writing while manipulating media to foster learning. Depending on how the teacher will arrange its contents and learning activities, one or several specific learning models will be engaged. In another learning activities, the same teacher may design differently its activities with other learning models engaged. This is what happens in the classroom, teacher are not stuck to one learning approach.
+The older proposal failed because it was not teacher centered but learner centered with a lot of romance. You want a system to be centered around its main prescriptor, the teacher. This is why in the Dynabook app model I described a dedicated [business model](https://github.com/hilaire/dynabook/tree/main/resources/doc/DynabookApp#business-objects), taking in consideration some of the professional constraints of the teachers, and the students as well.
 
 **---JR**: Can you explain what a *dynamic knowledge model* is?
