The "response" component is trickier, if ostensibly simpler. As respondent, your job is to evaluate the argument, presentation, question, problematics of the readings, in order to lead us into discussions. You may critique, ignore, complement with other information; you may set a few questions for the discussion to follow.
The factoids are factual presentations, about 5 minutes long. They may or not be written and distributed.
Discussion in a seminar is much more important than the written work, to a ratio of 3 to 1. By "discussion" ... well, see point 1 above. An "active" participant doesn't talk ALL the time.....
MIT Literature Statement on Plagiarism
Plagiarism--the use of another's intellectual work without acknowledgement — is a serious offense. It is the policy of the Literature Faculty that students who plagiarize will receive an F in the subject, and that the professor will forward the case to the Committee on Discipline. Full acknowledgement for all information received from sources outside the classroom must be clearly stated in all written work submitted. All ideas, arguments, and direct phrasings from someone else';s work must be identifies and properly footnotes. Quotations from other sources must be clearly marked as distinct from the student's own work. For further guidance on the proper forms of attribution, consult the style guides available on the MIT Website on Plagiarism.
