Einige Rechtschreibungsfehler hast du noch drin:
Wikis became more and more
popular during the last decade. The best example therefor is the
free encyclopedia Wikipedia. The question is, can wikis be used at a specialised secondary school, and if, in which sectors?
Many
projects at schools and universities have shown, the
usage of wikis for education provides realistic chances. The pupils are higher motivated (Honegger 2006) and the results better (De Pedro et al 2006b). But the
development is just at the beginning. People are needed, who optimise wikis for every day usage in classrooms. One of these optimisations might be AulaWiki, a Wiki distribution based on TikiWiki.
Davon abgsehen hast du teilweise etwas ungenau übersetzt, z.B. motiviert => higher motivated
Was du vielleicht noch ändern könntest:
People are needed for wiki optimisation ...
The question is whether wikis can be used at a specialised secondary school ...
