An Aspect Oriented approach to implement fault detection in automatic measurement systems is proposed. Faults are handled by means of “aspects”, a specific software unit to better modularize issues transversal to many modules (“crosscutting concerns”). In this way, maintainability and reusability of a measurement software are improved: indeed, once a modification of the fault detection policy o...

The need to adequately cover the content domain to certify achievement proficiency by producing meaningful precise scores requires many high-quality items. More 3-option items can be administered than 4or 5-option items per testing time while improving content coverage, without detrimental effects on psychometric quality of test score...
