Multitouch Learning Books (short: MLB) are digital interactive E-Books that can be used in class enriched with individual tools. Due to their multifunctionality, they offer an excellent framework for integrating further didactic functions exceeding the role of a learning companion. In this study a Multitouch Learning Book was developed which contains all three didactic functions of ICT (Information and Communication Technology). The MLB provides the digital framework for the series of lessons and accompanies the entire learning process. Learning tools include isolated applications, Augmented Reality and measured data logging, which fulfills the didactic function of an experimental tool. The topic "galvanic cell" was implemented and tested in two different classes. The intervention resulted in unanimously positive feedback from teachers and pupils alike
