About

eChemBook

Features

Read full description

Das digitale Chemieschulbuch eChemBook ist ein Prototyp eines elektronischen Schulbuchs und kann vergleichbar einem traditionellen Schulbuch im Unterricht eingesetzt werden. eChemBook ist im Rahmen eines von der Deutschen Forschungsgemeinschaft (DFG) geförderten Transferprojektes entstanden. Es enthält bisher die Themen „Teilchenmodell" und "Atommodell von Dalton“. Für die Aufgaben des E-Books wird "SMART Notebook App for iPad" benötigt. Entwickelt wurde das eChemBook von dem Institut für Didaktik der Naturwissenschaften der Leibniz Universität Hannover, dem Leibniz-Institut für Wissensmedien in Tübingen, dem Schroedel-Westermann Verlag und SMART Technologies. Diese App wurde für Studienzwecke entwickelt. Bei Interesse an einem forschungsbegleiteten Einsatz im Unterricht kontaktieren Sie bitte die Ansprechpartnerinnen der Studie, Nina Ulrich (ulrich@idn.uni-hannover.de) oder Juliane Richter (j.richter@iwm-tuebingen.de).
