Student questioning : a componential analysis

This article reviews the literature on student questioning, organized through a modified version of Dillon's (1988a, 1990) componential model of questioning. Special attention is given to the properties of assumptions, questions, and answers. Each of these main elements are the result of certain actions of the questioner, which are described. Within this framework a variety of aspects of questioning are highlighted. One focus of the article is individual differences in question asking. The complex interactions between students' personal characteristics, social factors, and questioning are examined. In addition, a number of important but neglected topics for research are identified. Together, the views that are presented should deepen our understanding of student questioning

The study set out to validate the supportive role of screen captures for switching attention. Forty-two participants learned how to work with Microsoft Excel with a paper manual.

The findings show that participants in all conditions looked up from the manual to the screen on about 97% of the cases in which such a switch was called for rank order analyses showed that users of the visual manuals switched attention significantly more often than did users of the textual manual. No differences were found between conditions on learning effects and training time
