Derick André, Lead Teacher – K

Derick André was born and raised in the French region of Switzerland. He has American and Swiss dual nationality. He grew up combining mostly French and English in his social life. However, he also had to learn German due to the different languages in his country. By having to learn those different languages, he was able to see how complex it is to learn different languages but he also realized how helpful it can be in social situations or for his own personal development and understanding.

Derick received his Bachelor’s degree in Education and Arts at the University of Lausanne in Switzerland. His degree combined studies and internships at the same time during 3 years to allow him to put theories into practice and  gain experience to analyze his teaching with internship leaders. His studies were focused on the development of the child, primary school pedagogy, French, English and German as a second language and physical education. Derick studied for one semester in Norway where teaching is at the highest level and continued discovering other countries with different systems of children education. Knowing how helpful it can be to speak and think with different languages, he acquired during his studies a desire to help students on other levels of interaction and understanding using the French language. He established throughout the years a good relationship with children by teaching, training swimming teams, organizing sports camps and being a camp counsellor. His devotion, energy and experience will contribute to increased skills of learning, to open access to knowledge, understanding the world and students finding themselves.
