The author chose that title for her audience. We are not her audience. We do not know she is a school teacher. To us, "Give 100 Percent" conveys something entirely different than to her audience.
I do not like un-necessary editorializing of material. If there is no title, sure, make a relevant title, but if the content producer has decided to present her material in a specific manner, its her call.
I do not agree that we are not her audience. We wont be discussing the issue at hand otherwise, would we? and that was her intent I suppose: To stimulate a discussion about teaching methodology among us, who care.
