If you find this frightening, ECR-491 may not be for you. In-class participation is not mentioned on the grading list because it is taken for granted that you will actively voice your thoughts or opinions in the class. Participation in group work will be evaluated by your peers. HTML code can be easily lifted from another web page and pasted into your own. This, in effect, is how design inventions are made.
Inventions only occur, however, if the code is altered to create a different effect.
This type of stealing I can accept. Stealing code or design work wholesale, however, is completely unacceptable. The only exception might be if you steal a text in order to create a parody of it. Text that you borrow must be cited according to MLA writing standards. You might be tempted to steal essays or articles from the Web since it is such a vast resource.
