I’m authoring a bank of questions in my subject area I’m authoring a bank of questions in my subject area I’m involved in the selection of a CAA system for my institution I’m involved in the selection of a CAA system for my institution I have a general interest in online learning and assessment I have a general interest in online learning and assessment

8 © 2001 By Default! A Free sample background from Slide 8 Basic response & render types Response types Response types –logical identifier –xy coordinate –string –number –logical group Render types Render types –choice –hot spot –fill in blank –slider –‘object’

9 © 2001 By Default! A Free sample background from Slide 9 True false example

10 © 2001 By Default! A Free sample background from Slide 10 True false example XML This is a simple True/False multiple-choice example. The rendering is a standard radio button style. No response processing is incorporated. Paris is the Capital of France ? True False

29 © 2001 By Default! A Free sample background from Slide 29 QTI: some problems For vendors For vendors –implementing QTI is costly –stops them from protecting their user base Vendors want simple specifications; users want broad, well-defined ones Vendors want simple specifications; users want broad, well-defined ones It is difficult to define specifications which do not have an effect on functionality It is difficult to define specifications which do not have an effect on functionality

30 © 2001 By Default! A Free sample background from Slide 30 Finally: why bother with QTI? Avoid lock in Avoid lock in –allow data to be moved in standard formats –allow one system to replace another Integrate systems from different vendors; allow choice of best assessment tool Integrate systems from different vendors; allow choice of best assessment tool Facilitate exchange of questions and tests between institutions, allow market to develop Facilitate exchange of questions and tests between institutions, allow market to develop Enable separation of content from presentation Enable separation of content from presentation Standard assessment records will facilitate student mobility Standard assessment records will facilitate student mobility
