Hi Offray,
From my understanding, the Dynabook concept is rooted to the idea of dynamic media or active essay and user engagement in producing this dynamic media contents. Etoys is a step in this direction, its innovative graphical programming environment supports the end user engagement in producing such dynamic media. I try to explain it in a previous article (http://blog.drgeo.eu/post/2018/The-Dynabook-Concept).
In my opinion, Scratch is not related to this dynamic media vision. It only borrows the concept of graphical programming environment to provide an accessible environment to initiate kids to programming and algorithmic. The Dynabook concept is very rooted to the constructivism movement and its learning models, which are not that effective according to researches. I discussed a bit about that on another article (http://blog.drgeo.eu/post/2018/The-Dynabook-and-its-learning-models) Nevertheless, teachers mix different teaching approaches, so I think it is interesting to look at the dynabook concept under the different teaching models coined as innovative. I wrote several small texts about that. Authentic learning pedagogy is one of this teaching model. In your example, your authentic document is your raw data and Grafoscopio is a scaffolding tool to make this data learnable. I am just guessing because I don't know Grafoscopio. What I found interesting in your case, is the central position of the text document. Text is such a handy media: video and audio run on the air then are gone, a text stays there under your vision, it is very easy to "play it" one paragraph backward or forward. In Dynabook there is this idea of dynamic book: text with dynamic content, I love it. As a teacher I will love to be able to produce textbook with text math and dynamic simulations (geometry, calculus, algebra micro-world) for the kids to learn with. Such dynamic simulations could just be pluggable Morph components, teachers will pick up and/or adapt to specific needs, eventually linkable, Ã la Etoys, and shared on the net, etc. Hilaire -- Dr. Geo http://drgeo.eu
