About the Book

Examensarbeit aus dem Jahr 2007 im Fachbereich Didaktik - Chemie, Note: 1,0, Sprache: Deutsch, Abstract: Das Gruppenpuzzle (engl. jigsaw ) wurde von einer Forschergruppe um den amerika-nischen Sozialpsychologen ELLIOT ARONSON als Unterrichtsmethode für die Schule entwickelt. Mit dieser kooperativen Lernmethode sollte prosoziales Verhalten in multi-ethnischen Klassen gefördert und der Selbstwert der Schüler gesteigert sowie ihre Leistungen verbessert werden. Aus dem Gruppenpuzzle wurde eine Vielzahl weiterer kooperativer Methoden entwickelt. Das Gruppenpuzzle wird in dieser Arbeit benutzt, um mit Schülerinnen und Schülern der Eingangsklasse eines Technischen Gymnasiums auf experimentellem Wege drei physikalische Trennverfahren (Chromatographie, Destillation und Extraktion) in einem zeitlichen Umfang von acht Unterrichtsstunden zu vertiefen. Eine schriftliche Wiederholungsarbeit rundet das Projekt als Kontrolle ab. Eine intensive Internetrecherche ergibt, dass zu Projekten dieser Art ("experimentelles Gruppenpuzzle") bislang keine Publikationen und Verweise existieren. Das Projekt zeigt, dass die Schülerinnen und Schüler konzentriert über einen längeren Zeitraum an einem Thema erfolgreich arbeiten können. Nach überwiegender Einschätzung der Lernenden ist die Auseinandersetzung mit physikalischen Trennverfahren in Form eines Gruppenpuzzles ein Erfolg. Die statistische Analyse der Testergebnisse unter Berücksichtigung der zuvor besuchten Schulform zeigt, dass ein erheblicher Leistungsgradient zwischen ehemaligen Gymnasiastinnen und Gymnasiasten und Schülerinnen und Schülern der Werkrealschule besteht: Absolventinnen und Absolventen der Werkrealschule schneiden in allen Bereichen bedeutend schlechter ab. Schülerinnen und Schüler, die von der Werkrealschule auf das Technische Gymnasium wechseln, müssen daher speziell in der Eingangsklasse besonders gefördert werden, um die Chancengleichheit zu wahren.
