Title

Children's Internet searching on complex problems : performance and process analyses

Source

Journal of the American Society for Information Science. 49(1998) no.9, S.840-849

Year

1998

Abstract

Examines the effects of task structure on elementary school students' information seeking on the Internet. 32 5th and 6th grade students searched on 2 tasks for information that was relevant to solving 2 problems. Information seeking process behaviours were analyzed by collecting computer trace data of each student's search. Information seeking performance was measured by 2 adult raters and by students' own judgements of all documents found. Analyses of students' process behaviours illustrated that children are interactive information seekers, preferring to browse rather than plan or employ systematic analytic-based searching strategies. Performance results indicated that children have difficulty finding relevant information on the Internet, however, children did search more effectively on the ill-defined task than on the well-defined one. When judging their own performance, students rated their work equally on both tasks, yet adult judges found that studented permormed significantly worse on the well-defined task
