today i view first witness of a process, that is happing in berlin schools - the introduction of 'smartboards' to substitude blackboards. in a still chalk-equipped class i spott those 'means of math instruction', that arouse sentimental memories. while sketching them i think, that my sympathy for this tools is not just sentimental. i believe, that use of chalk, a basic method of 'skripting' and construction, has an educational value and i would regret, if it was totally substituted by high tech pens and cad. luckily this school keeps its blackboards aside of the modern beamer equipped whiteboards. the teacher tells me, that they had to fight for the preservation of blackboards. they did, because the blackboard can be used easier quick and spontanously and the smartboards need maintenance and energy.
i hope, that other school do the same. analog 'skripting' fits well in a world, where sophisticated music still is performed by pulling horses hair over cats guts, that is calmped on a, preferable old. wooden container and human anatomy is demonstrated with bones, that do not look like casts.
