Pictures of GymGa
In 37 years as a teacher at the high school "Gymnasium an der Gartenstraße" I have always been one of my hobbies, photography, having introduced.
Math/Computer Sciences
The trigger was a sick student who missed several weeks of classes because of hospitalization and asked me to provide her with educational material. Since she had internet access,
My Hobbies
My oldest hobbies are dogs (as a child Collie Tramp) and photography. At primary school, I started with an Agfa Isola (photo Dirk Böhling), a simple camera for roll film sizes 6x6, which at that time was about 40 DM.
Mathematics
Mathematics and Computer, which was after my studies again an issue when I in 1982 I got my first advanced math course. When I "Analytic geometry and linear algebra" prepared on the subject, I remembered the book "Linear Algebra with the Computer" by Eberhard Lehmann's hands. On our few computers (Z80 processors), we realized in Alcor Pascal algorithms for matrix computations, which put us in a position to solve tasks that were not solvable with pocket calculators. Later, the Pascal program was replaced by a CAS system (MuPad), which unfortunately is no longer on the market, however. For everyday use, then programs such as "Geogebra" proved more practical, at least in the area of plane geometry and calculus. Although they were not as powerful as a CAS system, but easier for students and teachers to use.
The prolonged hospital stay of a student initiated the writing of some Javascript routines for specific tasks, such as fraction equations or polynomial division. This routines I made available for this student via the Internet. Of course, I have these scripts then also used in the classroom. The area of "mathematics" here is - at the moment - limited to these scripts.
Informatics
Since the early 80s, I teach at the high school "Gymnasium an der Gartenstraße (Garden Street)" computer science. First, in working groups, and later in normal courses. Since 1986 (after I had attended the relevant training) my students were able to choose computer science as a subject for their school leaving examination (Abitur).
One focus of the subject is on the programming. First, Pascal - mostly Turbo-Pascal - was the predominant dialect in the classroom. With the proliferation of object-oriented approach showed that Pascal met its limits here what is in my opinion the same for the Turbo Pascal Delphi successor. So I introduced in 1999 at our school Java as programming language. As a development environment I am using BlueJ, Greenfoot and Netbeans. These programs are in addition to Java to find all free on the Internet.
At this point I will, initially beginning with the introductory phase EF, introduce some teaching projects.
