Disabilities:
Elizabethtown College welcomes students with disabilities to participate in all of its courses, programs, and activities. If you have a documented disability and
require accommodations to access course material, activities, or requirements, you must: (1) Contact the Director of Disability Services, Lynne Davies, in the
Center for Student Success, BSC 228, by phone (361-1227) or email daviesl@etown.edu; and (2) Meet with the instructor within two weeks of receiving a
copy of the accommodation letter from Disability Services to discuss your accommodation needs and their implementation.
Academic Honesty: Elizabethtown College Pledge of Integrity: "Elizabethtown College is a community engaged in a living and learning experience, the
foundation of which is mutual trust and respect. Therefore, we will strive to behave toward one another with respect for the rights of others, and we promise to
represent as our work only that which is indeed our own, refraining from all forms of lying, plagiarizing, and cheating."

Changes: This syllabus provides a guideline to the expectations for the course; minor changes may be made during the semester
Semester Project
No project previously built for another course will be accepted. Groups of two preferred, but individual or groups of three may be approved.
PROPOSAL: Due date to be announced. Late penalties apply. Use PowerPoint. It should take approximately 5 minutes. At the very least do a
“GOOGLE SCHOLAR” search for your topic and discuss what you will be researching.
PRESENTATION: Due date to be announced. Late penalties apply. Use PowerPoint. It should take 10 minutes; Penalty applied if 15 minutes exceeded.
Tips on presentations:

Minimize unnecessary details

Less than 30 words per slide

Don’t have too many slides

Ensure good contrast between text and background (will the lights be on?)

A picture is worth a thousand words -- an equation or graph can be worth much more

Put an image on every page (clip-art, photo, animation) which is an abstraction of the subject

Don’t read from script

Don’t speak monotonically

Don’t have too many (or annoying) sound effects

Make eye contact with audience

Have a clear objective (to entertain, to sell, to motivate, or to report findings)

Have a good opener (an agenda, a quotation, a question, or a declaration)

Be organized and logical (present problem then solution; or have priorities – least-to-most or most-to-least)

Have audience’s expectations understood (provide meaning and/or motivation)

Have good transitions between main points

Have a good closing (summarize main ideas, restate purpose of presentation)

Be flexible (adapt if questions are asked during presentation)
PAPER: Late penalties apply. Must be in two-column, single-spaced, 10-point font using IEEE formatting dictated by:
http://users.etown.edu/w/wunderjt/IEEE_CONF_PAPER_FORMATTING.pdf. Paper should be 4 to 6 pages (2 to 3 if you decide to build something and it
works – not required or recommended for this course). Include:

An Abstract (one or two paragraphs)

An Introduction section

A number of discussion sections

A Conclusions section

A bibliography (a list of citations) – call it “References.” Excessive use of Wikipedia and non-scholarly citations will be penalized. See:
http://www2.etown.edu/library/scholarlyjournals.htm (USE LIBRARY and GOOGLE SCHOLAR !! )

Appendices for supporting materials (simulation code, sketches, data collected, manufacturers literature, etc.)
On final presentation day, submit before you present:
1. A printed stapled copy of your PowerPoint presentation; six slides per page
2. A printed stapled copy of your paper
3. All engineering majors put a copy of your group’s paper and presentation in your individual folder in the “Engineering Portfolios”
folder on the “J:” network drive.
4. Email your paper and presentation to me
