Computer Games
This film covers the topic of computer games in a variety of ways and from many different angles. Apart from the fascina- tion of computer games for users, the historical development as well as the production of computer games are described. The established genres are introduced, the guidelines of the German BPjM are explained. In light of recent public discussions, a neutral overview of the pros and cons of playing computer games is given, and different kinds of player behaviour are outlined. In this film, the pupils will recognise many aspects of their favourite pastime that encourage an independent, constructive use of this medium and reinforce their media competency. The film and teaching material are very closely related to the real-life situation.
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.
Air Traffic
Being able to fly has been a dream of humanity from time immemorial. But it does not even date back a century that people actually started being able to travel through the air. Since the 1960s, the number of flight passengers has been constantly increasing. Thus, the airspace is no longer dominated by birds but by man-made flying objects.
