Auf eine umfangreiche Erfahrung im Unterrichten kann ich leider noch nicht zurückgreifen, zumal ich mich hier zum ersten Mal für eine solche Tätigkeit bewerbe.
Bislang habe ich lediglich meinen schulpflichtigen Enkeln bei den Hausarbeiten geholfen.
Ich könnte mir allerdings gut vorstellen, in der Nähe meines Wohnortes bei den Kindern zuhause präsent zu unterrichten bzw. Nachhilfeunterricht zu geben, als auch über Video bzw. PC (Zoom usw).
Und nun das ganze etwas elaborierter in Englisch:

I am writing to express my strong interest in the position of an online English tutor at NACHHILFEUNTERRICHT. With my bilingual proficiency, experience in the United States, and passion for working with young students, I am confident that I can make a meaningful contribution to your team and the English language learning experiences of German-speaking children and adults.

Since I've often visited the United States (on business and pirivatly) I had the opportunity to immerse myself in the English language and culture. This experience not only honed my language skills but also exposed me to the nuances of American English, which I believe will be invaluable in teaching English to German-speaking learners.

My love for working with young students stems from my belief in the transformative power of education. I understand the unique challenges and learning styles of children and am committed to creating engaging lessons that cater to their specific needs. Additionally, my experience working with adult learners has equipped me with the flexibility to adapt my teaching methods to different age groups and skill levels.

Key qualifications that I bring to the role include:

* Strong proficiency in both English and German, enabling effective communication and explanation of language concepts.
* Willing to work using online teaching platforms and tools to facilitate remote learning.
* Mobility: If the student lives within a reasonable distance from my home in Rüsselsheim, I'd be glad to also teach at the students home, one on one.
* A creative and adaptable teaching style that fosters a positive and interactive learning environment.
* Excellent communication skills to build rapport with students and address their questions and concerns effectively.

I am excited about the opportunity to work with you and contribute to its mission of helping German-speaking individuals improve their English language skills and to achieve their language learning goals.

Sincerely,
Hans Theis
