Sir / Madam,(Honorable)
Concerning: application for the position of ...
With this letter I would like to respond to your vacancy of 14/02/2013 on the website .... I would like to apply for the position of German teacher at your school.
After having studied in Italy for two years where I worked as an German teacher, I am now back in the Netherlands and teach Dutch lessons in Germany. Living in different countries has given me a way with words. I am fluent in Dutch, Italian, German and English. During and after my conservatory training, I also worked as a guitar teacher.
During my studies at the conservatory, I learned about different educational methods. I consider myself a patient teacher with a lot of empathy. In 2010 I moved to Perugia, Italy where I taught German lessons in an interactive way to preschoolers at several schools. Through combining music, games and language I succeeded in teaching the principles of the German language.
I currently teach Ductch at a community college in Germany. I work with a class of adults. The course is called "Niederlaendisch auffrischung" and has as main objective the refreshment of previous acquired knowledge.
What really appeals to me in education are the dynamics and contact with students. It is a great satisfaction to me seeing students grow and develop during a school. Through my international and diverse experiences as a teacher, I have a strong cultural awareness and I am aware of the efforts and inspiration which come into play during the acquisition of a new language.
Your school appeals to me because of its international character and because your appreciation of high quality of education and progress.
I would like to further explain my application in a personal conversation.
Sincerely,
