Bedingte Wahrscheinlichkeiten
Bedingte Wahrscheinlichkeiten begegnen uns jedes Mal, wenn wir eine neue Information erhalten, die ein Ereignis unseres Interesses beeinflusst, beispielsweise einen Börsenkurs. Der Unterrichtsfilm löst die typischen Denkblockaden und vermeintlichen Widersprüche auf. Er vermittelt die Struktur der zugrunde liegenden Probleme anschaulich mit vielen Beispielen. Bedingte Wahrscheinlichkeit ist die Wahrscheinlichkeit des Eintretens eines Ereignisses unter der Bedingung, dass das Eintreten eines anderen Ereignisses bereits bekannt ist. Der Unterrichtsfilm greift u. a. das bekannte Ziegenproblem auf. Hierbei lässt sich sehr gut zeigen, dass der menschliche Verstand, die menschliche Intuition sehr leicht zu falschen Entscheidungen führt. Das zusätzlich auf der DVD befindliche Unterrichtsmaterial bringt viele praktische Beispiele und Übungen zur Vertiefung.

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.
Blogging
The weblog or blog, for short, as a medium is not much older than this century. Blogs came into being in the World Wide Web as ’messages from below’, as web pages from web creators who wanted to share their view of the world with the world. They are short notes, long texts, pictures, videos, which are posted loosely and at random intervals to the world for an undefined public.
Internet Addiction
The film consists of two parts. The first part is the 15-minute short film “In the Net”. It describes the problem of excessive Internet use in a humorous way, in particular the risk of losing touch with reality when chatting. The second part illustrates with three real persons how Internet addiction can develop and the problems encountered by those who are afflicted. The authentic statements are commented by an experienced therapist. For many pupils, the issues addressed here are related to their everyday lives. What is a “sensible” use of the Internet, where does pathological addiction start? In contrast to addiction to alcohol, nicotine or drugs, the public seems to be largely ignorant of the problem of this addiction, which is not related to any substance abuse. The film provides material for discussion in the classroom (crossdisciplinary) and can be used as a basis for the formulation of prevention strategies.
