On the technological ignorance in some e-learning researchers

I have a bad general feeling about a specific aspect during the panel "pedagogical aspects" in this conference. It's true that Technical problems need to be addressed very careful before classes start. As Maria Teresa Ciaffaroni told us with W.B. Yeats,

education is not the filling of a pail, but the lighting of a fire.

A lot of people talk about the constructivism learning perspective (with the usual references: Rogoff 1990, Duffy and Cunningham 1996, Vygotsky 1962, 1978) in a technological context totally unfit to the very perspective! But if you don't know the underlying technology basic choices (i.e. LMS vs. blogs vs. wikis) you can't really say something pedagogically new, as the fundamental decisions were already taken by someone else, in particular the software designers, usually -- but not always, as Ward Cunningham explains about wikis -- unaware of the underlying pedagogical framework.

Summary of my argument. We need an explicit learning theory, in order not to fall to the 'silver bullet' conception of technology. In fact, as Maria Teresa (again!) said: there is no ready-made software tool for learning suitable for every occasion once for all.
