Povzetek

Prispevek predstavlja sistem za samodejno generiranje nalog in njihovo ocenjevanje, razvit na IMFM v okviru projekta Aktivna matematika. Razlog za vpeljavo sistema je bil, da kljub močnemu vplivu IKT na način preverjanja znanja, predvsem z avtomatizacijo pri kreiranju vprašanj in ocenjevanju, ima le-to tudi slabe plati, ki so še posebej razvidne pri matematiki. Učenec namreč lahko poda pravilen odgovor, a ker je v drugačnem zapisu, ga sistem ne po prepoznal kot pravilnega. Naša rešitev prepozna enakovredne odgovore in odpravlja še mnogo drugih težav preverjanja, kot sta prepisovanje in učenje odgovorov »na pamet«.

Abstract

The paper presents a system for automated generation and assessment of exercises. The system was developed at IMFM as part of the Active Mathematics project. This system was developed because, although ICT has had a major impact on knowledge assessment through automation in question creation and grading, the process is not without flaws, which are particularly evident in mathematics. A student could for example answer correctly but be marked wrong because his answer is not in the same form as the teacher's. Our solution can recognise equivalent answers and also prevents cheating and memorising the answers beforehand.
