Sinus
Flächensätze IV
Der persische Mathematiker und Astronom Abu l-Wafa entdeckte und beschrieb im 10. Jahrhundert in der Trigonometrie den Zusammenhang zwischen einer Seite und dem ihr gegenüberliegenden Winkel.
Die Sinusfunktion, eine elementare Funktion der Mathematik, beschreibt das Verhältnis der Gegenkathete zur Hypotenuse in Abhängigkeit vom Winkel.
Die DVD leitet in einem ersten Teil die Sinusfunktion her und führt die Beweise.
In einem zweiten Teil wird das Wissen in zahlreichen unterhaltam und übersichtlich animierten Aufgaben angewandt und vertieft.
In Verbindung mit dem umfangreichen Zusatzmaterial (klassische und interaktive Arbeitsblätter, Glossar, Testfragen) ist die vorliegende DVD hervorragend für den Einsatz im Unterricht geeignet.

Peer Mediation
Lena and Max attend the 7th form. Max is new in class. During a break, Max notices that Lena and her friend are laughing at him again. Max loses his temper! He slaps Lena in the face. That hurts and Lena runs back into the classroom with a red cheek. The growing conflict between the two has escalated. Just like Lena and Max, every day pupils all over Germany have rows with each other. At the Heinrich Hertz Gymnasium in Thuringia, pupils have been trained as mediators for years. At set hours, they are in a room made available by the school specifically for mediation purposes. The film describes the growing conflict between Max and Lena and shows a mediation using their example. In doing so, the terms “conflict” and “peer mediation” are explained in a non-technical way. The aims of peer mediation and its progress in five steps as well as the mediators’ tasks are illustrated. The art of asking questions and “mirroring”, which the mediators must know, is described and explained. Together with the comprehensive accompanying material, the DVD is a suitable medium to introduce peer mediation at your school, too.

Product Piracy
Counterfeiting takes place in almost all economic sectors – textiles, watches, car parts, machine parts, tools, accessories, software and medicines. Some counterfeits are easy to recognise, others are so well-executed that even experts have difficulty distinguishing between original and imitation. This DVD covers the development of a product from idea to manufacture. Once a product has become a trademark, product pirates appear on the scene.
