    Abstract
    Unsere Medienwelt ist vom Nebeneinander verschiedener Ausgabeformen derselben Inhalte geprägt. Es herrscht jedoch Mangel an Untersuchungen, welche die "usability" von Printmedien mit der von Online-Medien direkt vergleichen. Im Rahmen eines Projektseminars am Institut fürBibliothekswissenschaft der Humboldt- Universität Berlin wurde die Usability von gedruckten und von Online-Informationsmitteln anhand heuristischer Kriterien verglichen. Als Benutzungsaspekte bündelndes und messbares Kriterium wurde der Zeitbedarf zur Beantwortung einfacher Testaufgaben ermittelt, die sowohl anhand der Print- als auch anhand der Online-Version je eines Versandhauskatalogs und eines Vorlesungsverzeichnisses zu beantworten waren. Die Prognosen sowie die Ergebnisse dreier Gruppen (Bibliothekswissenschaft-Studenten, Informatik-Studenten und Laien) wurden verglichen. Der Zeitbedarf für die Nutzung der Printmedien wurde von den Bibliothekswissenschaft- und Informatik-Studenten zu hoch prognostiziert, für Online-Medien zu niedrig. Der tatsächliche Zeitbedarf bewegte sich in ähnlicher Größenordnung bei beiden Versionen des Vorlesungsverzeichnisses. Bei der Nutzung des Versandhauskatalogs hingegen war der Zeitbedarf online doppelt so hoch wie beim Printmedium. Zusätzlich war bei Nutzung der Online-Version die Hälfte der Antworten falsch. Der Grad an subjektiver Unsicherheit über die Richtigkeit der Antworten wurde, damit übereinstimmend, bei der Online-Version deutlich höher eingeschätzt als beim Printmedium. Die Testergebnisse derdrei Gruppen unterschieden sich beim Versandhauskatalog nur wenig. Die Ergebnisse werden als Hinweis auf schlechten Entwicklungsstand der Usability von Online-Medien gedeutet. Die Usabilityvon konventionellen Medien scheint von "computernahen" Nutzern unterschätzt zu werden. Bei der Nutzung von Online-Medien wird in derLiteratur oft hohe subjektive Unsicherheit über die Angemessenheit oder Richtigkeit der Suchresultate berichtet, die hier bestätigt wird und zugleich mit einem hohen Anteil objektiv falscher Antworten korrespondiert. Es wird dafür plädiert in die Usability-Forschung konventionelle Medien einzubeziehen und stärker interdisziplinär vorzugehen.

    Beobachtungen und Befragungen Da kommen die beiden vorliegenden Studien gerade recht, untersuchen sie doch mit qualitativen Methoden, mit Befragungen und teilnehmenden Beobachtungen, wie Kinder das Internet entdecken beziehungsweise nutzen, welche Kompetenzen sie haben und entwickeln, welche Erwartungen, Interessen und Präferenzen sie für das Netz haben, wie und welche Orientierungen und Suchstrategien sie entfalten und schließlich wodurch und wie sie sich von den Web-Sites ansprechen lassen. Das wird jeweils an einzelnen Beispielen und Szenen anschaulich beschrieben, teils wörtlich dokumentiert, sodass man plastische Eindrücke bekommt, wie Kinder an das Web herangehen, wie sie sich zurechtfinden und was sie darüber denken und wissen. Die eine Studie (Christine Feil et al. 2004) wurde zwischen 2001 und 2003 am Deutschen Jugendinstitut (DJI) München mit Unterstützung des Bundesministeriums für Bildung und Forschung durchgeführt; an ihr sind mehrere ForscherInnen beteiligt gewesen. Entsprechend komplexer und differenzierter sind ihre Erhebungsmethoden, entsprechend aufwendiger ist ihr Forschungsdesign, und entsprechend umfassender und dichter sind ihre Ergebnisse. Teilgenommen an der Studie haben elf Mädchen und sieben Jungen zwischen fünf und elf Jahren; sie wurden in zwei bis drei mindestens einstündigen Beobachtungsphasen in ihrem Umgang mit PC und Internet per Video beobachtet, zweimal befragt wurden die Eltern und die Erzieherinnen der Horte, in die die Kinder gehen. Die andere (Susanne Richter 2004) ist eine literaturdidaktische Dissertation an der Universität Lüneburg, deren empirischer Teil schon 1999, also drei Jahre früher als die DJI-Studie, durchgeführt wurde. Beteiligt waren 25 Schüler, darunter nur sechs Mädchen, zwischen zehn und 13 Jahren, die von der Autorin nach ihrer PC-Nutzung befragt und während einer halbstündigen »Surfphase« über vier ausgewählte Web-Sites beobachtet wurden. Mithin sind die Populationen allenfalls für die neun 10- bis 11-Jährigen der DJI-Studie vergleichbar, die andere Hälfte ist jünger.

    Abstract
    This study investigated Simon's behavioral decisionmaking theories of bounded rationality and satisficing in relation to young people's decision making in the World Wide Web, and considered the role of personal preferences in Web-based decisions. It employed a qualitative research methodology involving group interviews with 22 adolescent females. Data analysis took the form of iterative pattern coding using QSR NUD*IST Vivo qualitative data analysis software. Data analysis revealed that the study participants did operate within the limits of bounded rationality. These limits took the form of time constraints, information overload, and physical constraints. Data analysis also uncovered two major satisficing behaviors-reduction and termination. Personal preference was found to play a major role in Web site evaluation in the areas of graphic/multimedia and subject content preferences. This study has related implications for Web site designers and for adult intermediaries who work with young people and the Web

    Abstract
    Bilal, in this third part of her Yahooligans! study looks at children's performance with self-generated search tasks, as compared to previously assigned search tasks looking for differences in success, cognitive behavior, physical behavior, and task preference. Lotus ScreenCam was used to record interactions and post search interviews to record impressions. The subjects, the same 22 seventh grade children in the previous studies, generated topics of interest that were mediated with the researcher into more specific topics where necessary. Fifteen usable sessions form the basis of the study. Eleven children were successful in finding information, a rate of 73% compared to 69% in assigned research questions, and 50% in assigned fact-finding questions. Eighty-seven percent began using one or two keyword searches. Spelling was a problem. Successful children made fewer keyword searches and the number of search moves averaged 5.5 as compared to 2.4 on the research oriented task and 3.49 on the factual. Backtracking and looping were common. The self-generated task was preferred by 47% of the subjects.
