Using IT to assess IT: Towards greater authenticity in summative performance assessment

The study found that both the digital portfolio and computer-based exam were implemented without significant technical difficulty and were well accepted by the students and teachers. The work output in digital form was readily accessed from an online repository by external markers using a standard web browser. The two methods of marking provided highly reliable scores, with those from the comparative pairs method being the more reliable. A number of questions of validity and manageability were raised and the strengths and weaknesses of the two forms of assessment revealed. It was concluded that it was feasible to implement either form of assessment for high-stakes purposes, with a resulting improvement in alignment and authenticity.
