The metacognitive knowledge of adolescent students during the information search process

Bowler, Leanne January 2008 (has links)
Metacognitive knowledge is a critical piece of the information literacy puzzle. In a world of exploding information and communications possibilities, the difficulty for users of information systems and services may not lie in finding information but in filtering and integrating it into a cohesive whole. To do this, they must be able to make sense of it, an act that assumes knowledge about one’s own information needs, goals and abilities. This type of self-knowledge - called metacognitive knowledge - has three basic components: knowledge of one’s self, knowledge of the nature of a cognitive task in relation to one’s own cognitive abilities, and knowledge of how and when to effectively use cognitive strategies to complete a cognitive task. Such knowledge, when used in information seeking, may help users to solve complex information problems. There is perhaps no other user group who could benefit more from the development of metacognitive knowledge than adolescents, aged 16 to 18. On the cusp of adulthood, they face many of the complex information problems of adults, but as “novice adults” their depth of knowledge on most topics may be shallow simply because they have only experienced life for a handful of years. This study used naturalistic research methods to investigate the metacognitive knowledge of adolescents as they searched for, selected and used information for a school-based, inquiry project, within the framework of Kuhlthau’s Information Search Process (ISP). It was conducted over a four-month period in a Montreal-area CEGEP (post-secondary educational institutions in Quebec). The participants were students in their first year of CEGEP (equivalent to grade 12). Ten participants, ranging in age from 16 to 18, each kept a written or audio journal in which they recorded their thoughts, feelings, actions, and self-prompting questions, participated in four interviews, three conducted by telephone and one face-to-face, and completed a visualizing ex / La connaissance métacognitive est essentielle à la maîtrise de l’information. Dans un monde où les possibilités en matière d’infonnation et de communication ont explosées, la principale difficulté pour les utilisateurs des systèmes et des services d’information ne consiste pas tant à trouver l’ infonnation qu’à la filtrer et à l’intégrer à un tout cohérent. Pour y arriver, ils doivent être en mesure de la comprendre, ce qui présuppose la connaissance de ses propres besoins, objectifs et habiletés en matière d’information. Ce type de connaissance de soi - appelé connaissance métacognitive - est constitué de trois composantes de base: la connaissance de soi, la connaissance de la nature d’une tâche cognitive en relation avec ses propres habilités cognitives et la connaissance du comment et du quand utiliser efficacement les approches cognitives pour effectuer une tâche cognitive. De telles connaissances utilisées pour rechercher de l’information peuvent aider l’utilisateur à résoudre des problèmes d’information complexes. Le groupe d’utilisateurs à qui le développement de la connaissance métacognitive peut profiter le plus est probablement celui des adolescents de 16 à 18 ans. Sur le point de devenir des adultes, ils sont confrontés à nombre des problèmes d’information complexes des adultes, mais en tant que jeunes adultes, la profondeur de leur connaissance dans la plupart des domaines peut être limitée, leur expérience de la vie ne reposant que sur quelques années. La présente étude a employé les méthodes qualitatives de recherche en milieu naturel pour analyser la connaIssance métacognitive des adolescents pendant qu’ils recherchaient, triaient et utilisaient l’ infonnation pour un projet de recherche scolaire dans le cadre du processus de recherche d’information (Information Search Process (ISP)) de Kuhlthau. L’étude s’est poursuivie sur une période de quatre mois dans un des cé
