    Abstract
    Previous studies have examined various aspects of user behavior on the Web, including general information-seeking patterns, search engine use, and revisitation habits. Little research has been conducted to study how users navigate and interact with their Web browser across different information-seeking tasks. We have conducted a field study of 21 participants, in which we logged detailed Web usage and asked participants to provide task categorizations of their Web usage based on the following categories: Fact Finding, Information Gathering, Browsing, and Transactions. We used implicit measures logged during each task session to provide usage measures such as dwell time, number of pages viewed, and the use of specific browser navigation mechanisms. We also report on differences in how participants interacted with their Web browser across the range of information-seeking tasks. Within each type of task, we found several distinguishing characteristics. In particular, Information Gathering tasks were the most complex; participants spent more time completing this task, viewed more pages, and used the Web browser functions most heavily during this task. The results of this analysis have been used to provide implications for future support of information seeking on the Web as well as direction for future research in this area.

    Abstract
    This study details the activities and strategies that 11th grade students with high academic abilities used during their information seeking and use to complete class projects in a Persuasive Speech class. The study took place in a suburban high school in Maryland, and participants included 21 junior honors students, their teacher, and their library media specialist. Each student produced a 5-7-minute speech on a self-chosen topic. Conducted in the framework of qualitative research in a constructivist paradigm (E.G. Guba, & Y.S. Lincoln, 1998), the study used data collected from observations, individual interviews, and documents students produced for their projects - concept maps, paragraphs, outlines, and research journals. Interview and observation data were analyzed using the constant comparative method (B. Glaser & A. Strauss, 1967) with the help of QSR NVivo 2 (QSR International Pty Ltd, 2002); students' documents were analyzed manually. The findings show that students' understanding, strategies, and activities during information seeking and use were interactive and serendipitous and that students learned about their topics as they searched. The research suggests that high school honors students in an information-rich environment are especially confident with learning tasks requiring an exploratory mode of learning.

    "Als Generation @ werden Kinder und Jugendliche in der Öffentlichkeit bereits gefeiert, insbesondere Marketing und Werbung schwärmen vom geschickten, unermüdlichen Surfen im WWW, von kinderleichter Handhabung des Equipments, spielerischem Edutainment und spannenden Verlockungen des digitalen Lernens, und zwar schon für die Kleinsten ab dem Kindergartenalter. Mehrheit noch offline Imposant sind auch die quantitativen Daten zur Haushaltsausstattung und PC- beziehungsweise Internetnutzung, vor allem ihre Wachstumsraten, die die Studie von Christine Feil und Co-Autoren referiert und miteinander abgleicht. Susanne Richter (S. 18) hingegen weiß nichts von ihrer Existenz, zumal Angaben aus kommerziellen Kontexten meist zu Obertreibungen neigen. Seriöser sind die Angaben des so genannten Medienpädagogischen Forschungsverbundes Südwest, der seit 1999 die Studie »Kinder und Medien« (»KIM-Studie«) durchführt, 2003 zum vierten Mal. Danach hatten 57 Prozent der bundesdeutschen Haushalte mit 6- bis 13-jährigen Kinder Internet zu Hause (Feil S. 15),42 Prozent der 6-bis 13-Jährigen besuchen hin und wieder das Internet, nur etwa gut zwölf Prozent sind täglich oder mehrmals in der Woche nach Schätzungen durchschnittlich zwischen einer halben und einer Stunde im Netz, werden aber von kommerzieller Seite bereits als »Heavy User« apostrophiert (Feil S. 18). Etwa bei zehn, elf Jahren lag 2003/2004 das Einstiegsalter für das Internet, bei Mädchen und bei Kindern aus niedrigeren Einkommens- und Sozialschichten etwas später. Offenbar haben die inzwischen - auch schon im Primarbereich - gut ausgestatten Schulen noch »kaum kompensatorische Wirkung im Sinne gleicher Zugangschancen für alle Kinder« entfaltet, »sondern allenfalls den Anteil der Kinder mit Sowohl-als-auch-Zugang« erhöht (Feil S. 21). So zeichnen sich tendenziell zwar jeweils steigende Beteiligungen ab, aber »die Mehrheit der Kinder« ist noch »offline«. Und der Zugang der Kinder zum Netz allein »gibt weder Aufschluss über ihre Nutzungskompetenzen noch über die Bedeutung der Kommunikationsund Informationsfunktion des Internets für Kinder« (Feil S. 30), so die sicherlich stimmige Ausgangsthese.
