About the Book

Examensarbeit aus dem Jahr 2004 im Fachbereich Didaktik - Chemie, Note: 2,7, Westfälische Wilhelms-Universität Münster (Institut für Didaktik der Chemie), Sprache: Deutsch, Abstract: Im Jahr 1997 formulierte die Gesellschaft Deutscher Chemiker in einer Mitteilung ihre Position zum naturwissenschaftlichen Unterricht: "In einem Jahrhundert, dessen Weltbild von Naturwissenschaft und Technik geprägt ist, und in einem Land, dessen Wohlstand sehr von Innovation und Erfolg im naturwissenschaftlichen Bereich abhängt, muß eine stärkere naturwissenschaftliche Komponente zum Pflichtbereich aller Oberstufenschülerinnen und -schüler gehören." (Mitteilung der GDCH 1997, S. 28) Sie bedenkt den naturwissenschaftlichen Unterricht also schon in der schulischen Ausbildung mit einer hohen Priorität. In diesen Bereich fällt natürlich auch der Chemieunterricht. Betrachtet man den Unterricht in der Chemie, so gibt es in der Didaktik diverse Ansätze um diesen zu verbessern und Vermittlungsprozesse zu fördern. Ein Ansatz ist die Evaluation von Vorstellungen der Schüler vor und nach Unterrichtsreihen zu bestimmten Themen. Eines dieser Themen ist der Bereich der Säuren und Basen, der in der Chemie mannigfaltige Anwendung findet und für ein Grundverständnis von dieser Naturwissenschaft unabdingbar ist. Neben den Säure - Base - Reaktionen selber, finden diese Stoffe eine Vielzahl von Anwendungen in anderen Themenfeldern, wie der organischen Chemie im Bereich der Carbonsäuren, als Katalysatoren oder Reaktionspartner. Ebenso sind die sauren und basischen Milieus für eine Vielzahl von RedOx - Reaktionen essentiell. Säuren und Basen stellen aber auch einen nicht geringen Anteil in der Lebenswelt der Schülerinnen und Schüler dar. Ob nun die Problematik des sauren Regens oder die großtechnische Synthese und Anwendung von Säuren, wie z.B. Schwefelsäure, immer wieder sind bei Verfahren und Problemen Säuren und Basen ein wichtiger Bestandteil. Die vorliegende Arbeit beschäftigt sich mit den Säuren und
