Stochastik 1
Mehrstufige Zufallsexperimente
Die Stochastik, zu Deutsch: die Kunst des Vermutens – auch Wahrscheinlichkeitsrechnung genannt – ist für die meisten Schüler und Schülerinnen ein ungemein schwieriges Kapitel der Mathematik, da die so oft in der Praxis angewendete Intuition hierbei nicht selten versagt. Anhand verständlicher Erklärungen und ausführlicher Beispiele erklärt der Unterrichtsfilm Zufallsexperimente wie das Urnenmodell, die Laplace-Regel, das Bernoulli-Experiment und vieles mehr. Ein Zufallsexperiment bezeichnet einen Versuch, der unter genau festgelegten Versuchsbedingungen durchgeführt wird und einen zufälligen Ausgang hat. Als Versuch versteht man hier einen Vorgang, bei dem mehrere Ergebnisse eintreten können, und bei dem ein nicht vorhersehbares Ergebnis eintritt, zum Beispiel das Werfen einer Münze oder eines Würfels. Das zusätzlich auf der DVD befindliche Unterrichtsmaterial bringt viele praktische Beispiele und Übungen zur Vertiefung.

The Daily Newspaper
Every day, there is a surge of news reaching us via different news channels. In spite of TV and Internet, the daily paper still is one of the most important main sources of news. But how is a newspaper created? The film shows the production of a paper in the course of one day. Starting with the editorial meeting in the morning, in which the topics and deadlines are determined, the film accompanies a journalist during her research work. You can see how a journalistic interview is conducted and what the photographer must consider when taking a press photo. Back in the editorial office, the editor’s work is illustrated, which includes the page layout and the writing of an online article in today’s time. Impressive pictures from the printing centre depict the process from the digital page to the finished newspaper. Together with the comprehensive accompanying material, the DVD is perfectly suited for use at school
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.
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.
