Professional Development of experienced Teachers -<br />

H. J. Brenner<br />

Albert-Schweitzer-Gymnasium, Erfurt, Germany<br />

1 Preliminaries<br />

Professional development of experienced teachers of mathematics should be<br />

a major issue, both school administrators and teachers should be concerned<br />

about. I have been dealing with proposals for improving the possibilities of<br />

learning mathematics for the past 13 years.<br />

In workshops for teachers of mathematics in Thuringia I present my ideas,<br />

practise and discuss certain activities with them. The aims of my paper are to<br />

explain reasons for my suggestions, my approach to teaching and furthermore<br />

to introduce the mathematical contents I selected because of my<br />

contemplations. I would like to contribute to the clarification of the question of<br />

how to become a teacher educator. There is a real need of professional<br />

competence.<br />

I am teaching the subjects mathematics and physics at the Albert-Schweitzer-<br />

Gymnasium Erfurt.<br />

2 Professional development and lifelong learning<br />

“The education of teachers of mathematics is an ongoing process … that<br />

spans a career. Teachers' growth requires commitment to professional<br />

development ... Their growth is deeply embedded in their philosophies of<br />

learning, their attitudes and beliefs about learners and mathematics, and their<br />

willingness to make changes in how and what they teach.” (NCTM 2012)<br />

According to this statement one has to find out what teachers’ attitudes<br />

towards mathematics are influenced by (including school mathematics) and<br />

what leads to disturbances and to use these findings as a chance to manage<br />

problems in a positive manner. One has to pay attention to the fact that the<br />

attitudes are deeply rooted and the time for intensive learning processes is<br />

very restricted because of the sometimes difficult working conditions.<br />

Apart from this one has to take into consideration that the mathematical<br />

content knowledge und the pedagogical content knowledge are closely<br />

combined with each other and should be developed at the same time. For the<br />

reason that the pedagogical content knowledge is linked with mathematical<br />

tasks prepared for the use in the lessons (Bromme 1992) special mathematical<br />

themes have to be presented by appropriate problems and in connection with<br />

tasks. “What many teachers lack is mathematical knowledge that is useful and<br />
