Technology lessons in English for ESO/Bachiller students

I'm a 9 year experienced engineer with career in international companies located in Castellón. I also have experience as teacher of matters like technology, technical drawing and physics, giving lessons to teenagers while I was studying my degree at the University of Castellón.

I came up with the idea of teaching these lessons in English because I see it as a good opportunity to learn not only technology, but also lots of vocabulary which is not usually taught at school.

I'd also like to focus the lessons not only on the homework duties and preparing the exams, but also to try to make my pupils feel a bigger interest for technology and engineering and motivate them to guide their careers in this field.
