I'm preparing a work experience letter in which I am expected to include my responsibilities in previous companies. In one of the companies I was holding some classes for other staff. But I'm not sure what is the formal, common and correct way of saying:
"Holding Object Orientation classes as a teacher for the IT staff"
To clarify, I don't know which verb (holding, teaching conducting, etc) could imply that I was the one who held the class and also was the teacher.
Could you please help me with this?
