| Tiivistelmä: | Here, the conceptual model of perceived task complexity, which incorporates the user, task, and system into a comprehensive unit of analysis, is used to investigate how, when, and why computer-assisted instruction (CAI) systems provide effective support. The work is based on data provided by 156 experimental subjects; information system (IS) use was found to vary by user groups depending on task performance. In addition, the effects of task presentation on task behavior and performance were found to vary between groups, based on their performance. |
