Assessing ICT literacy via computer

ICT literacy is about using computer technology to access, manage, evaluate and create&#160,information, and communicate it appropriately. The last few years have seen dramaticchanges in computer technology and how it is used, particularly by young people. Think of&#160,tablets and smart phones, &#8220,apps&#8221,, cloud computing, wireless connectivity, social media,&#160,crowd-sourcing and so on. Is there a valid ICT literacy construct that remains stable and&#160,relevant despite all these changes? This paper describes a computer-based test instrument&#160,that was recently developed and used to measure ICT ability in 10 000 Australian students&#160,in Grades 6 and 10. The instrument consists of a suite of modules containing authentic&#160,simulated environments with which students interact on-line to demonstrate their ICT skills.&#160,The modules attempt to take into account the recent changes in technology. The instrument&#160,is contended to have a high degree of validity. The construction process, the contents of the&#160,modules and an IRT analysis of the response data are discussed in this paper in support of&#160,this contention.Keywords: ICT, Assessment, Computer-based test, Validity.
