The discussion of mapping in absract or lay language reminds me of "The hundred languages of children" from Reggio Emilia. There is no reason to ostracize a minority language, such as tech terms from a research field, as long as it's not mandatory for everyone. But we need some universal translators or Babel fish. Diagrams may be more universal than words.
Love the anatomy of Babel fish - and yes, we do need universal translators, and yes, no need to ostracise the strange language of academics.
Jutta (in Austria) will be running her next workshop using some of the images in the new mapping sheet - although I dont know in detail how she want to use them - it'll be interesting to see, and interesting to find out if the images 'travel' or not.
