Do two heads search better than one? Effects of student collaboration on web search behaviour and search outcomes

This study compared Pairs of students with Single students in web search tasks. The underlying hypothesis was that peer-to-peer collaboration encourages students to articulate their thoughts, which in turn has a facilitative effect on the regulation of the search process as well as search outcomes. Both hypotheses were supported by the results. Pairs located the target information more often and in less time than Singles did. Pairs also employed a richer repertoire of search strategies and were more proficient in monitoring and evaluating their search behaviour. Implications of these findings for practice and further research are discussed.
