 papers 1-3 you must use 3 papers
from lit
 to be kind I have a prelim list
of papers on the web site
 To be kind, I will review an outline
of your paper once and a final version of your paper once. I promise a 48 hr
(working days) turnaround. Requirements - at least two papers I have
not seen and turn in copies of those papers.
 Save on z:/share/imfge/ie775/papern directory and
turn in a paper copy. Save in the format lastnamen,
where n is the paper number
 Register book topic on the website (must be
approved first).
 Use the writing lab prior to talking with me.

Use page numbers - 1,2,3,etc.
Abstract <150 words - what’s the big idea???
Format bib/ref consistently
Bib/Ref - use journal first, then conf, then web.
Look at other papers (SJET paper)
No lists (few) WRITE!!!
Spelling/grammar
If you don’t understand something - don’t write
about it!!!!!
cIm -IE775
Paper suggestions
 Give it to a friend and they ask “what does this
mean?” If they can’t answer, then rewrite!!!

 Don’t kill yourself!!!
cIm -IE775
Plagiarism
 If it is not your words (if you copy word for word)
must be in quotes with ref at the end.
 If it is mostly from one or two papers, you need to
put the ref at the end.
 If I find ONE place of plagiarism, the paper gets a
zero
 You have one week to fix it, if I find another place
with plagiarism, you still get a zero, if not your
score is half what it would have been.
cIm -IE775
Reaction Paper
 First, choose 2-4 papers on the topic
 Before reading the paper/book, look it over, reading the
chapter titles, subheadings, opening lines of chapters--not really reading, but skimming--to get a
flavor for what the readings are all about. Then write a short paragraph which explains your specific
goals and expectations (what you hope to gain by studying this material). Some things to think about
when writing the paragraph could be: your reasons for selecting the course, the types of changes you
might consider making in your use in your work upon learning more about the topic, or any way the
topic might help you in your job. 33 points
 After reading the complete paper(s)/book, write the main
section of your Reaction Paper, which should be based on your own responses to the ideas and
resources presented in the book. This section should run from 2 to 3 pages, and should give the reader
not only your reaction to the material presented, but also a sense of your particular professional
background/work situation. In other words, the Reaction Paper is not simply a summary of the content
of the book; it is a synthesis of the significant ideas in the book and your own professional knowledge
and experience. 33 points.
 Describe how you might incorporate these ideas
into your daily work. These initial thoughts you have on possible professional
applications might be the seed for your Internet-based Project. Discuss how the ideas in the book
might need to be modified to meet your particular work situation. Also, discuss any ways in which
these materials are not suitable for your particular professional application and critique them
accordingly. 33 points
