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.

My Webprojects

Gymnasium an der Gartenstraße (closed 2016)

Since the spring of 1996, I am responsible for the homepage of the grammar school "Gymnasium an der Gartenstraße" ... . Within the framework of the project " Schools on the Net ", which was initiated at

SV Helpenstein (current)

In 2012, I took over the responsibility for the website of the SV Helpenstein. Hosted at the provider Alfahosting the website is based on the CMS Joomla 3.3.x.

Museum Schloss Rheydt (ended 2002)

In 1998 I created with some pupils (project team Internet), supported by the project group photography from Mr. Mennicken and the advanced course English by Mrs Hochheimer, at the request of the former museum director, a homepage for the city's Museum Schloss Rheydt.

Heinsberg city tour (current)

In 2020 I built this website for the Heinsberg city guides Helmut Hawinkels and Wolfgang Gruber ( www.heinsbergerstadtfuehrungen.de ). Hosted at the provider Alfahosting the website is based on the CMS Joomla 3.9.x..

Informatics

Introductory phase (EF): In the early stages of teaching computer science in the EF there are different approaches eg with Greenfoot. Here I will but introduce projects realized with Netbeans. the first projects deal with simple graphics and string manipulations. Based on the graphic examples, an entrance to the object-oriented programming (ball as moving circle, billiard ball subclass of ball knows a pool table, circle and square as a subclass of the abstract class figure, polymorphism, etc.).

Qualifying phase I (Q1): A first project deals with recursive algorithms, then various projects follow on "Linear Data Structures" (List, Stack, Queue) and on the theme of "Searching and Sorting". Finally, projects are being implemented to tree structures.

Qualification Phase II (Q2): Here various projects for client / server programming are presented.

network administration programming

TRS 80 or computer conquer the Gymga

The beginnings of computer use in the grammar school "Gymnasium an der Gartenstraße" can not be determined unambiguously. When I came to this school in 1978, Mr. Dipl . Ing. Maser ( teacher of mathematics at the school at the time )

Open School Server

As of 2003, our school received two new computer classrooms and the infrastructure for networking in this context , I found myself confronted with two problems. The first was the establishment of a domain server.

Programming

First programming experience I gained during my studies of mathematics in Aachen in the languages Fortran and Cobol. At high school "Gymnasium an der Gartenstraße", I learned first of all Basic, because that was the programming language which was already implemented in the ROM of TRS 80 computer.
