English units.
Grading:
Homework 10%
Best 4 of 5 quizzes 10%
Design Problems 10%
1st Exam 20%
2nd Exam and Final 25%
Grades
will be converted to a T score by the following formula,
T-score = (Exam Score - Class Mean) /
Class Standard Deviation
|
T-Score |
Grade |
|
1.2 or higher |
A |
|
1.0 to 1.199 |
A- |

.8 to.999 |
B+ |
|
0.4 to .799 |
B |

0.2 to .399 |
B- |
|
0.0 to .199 |
C+ |
|
-.4 to -.001 |
C |

-.6 to -.399 |
C- |
|
-.8 to -.599 |
D+ |
|
-1.0 to -.799 |
D |
|
-1.0 or less |
F |
The T score will set the minimum grade
that can be given. The T score grade can
be improved with better grades in the latter part of the course demonstrating a
competence in subjects with a poor grade in the first part of the course.
There will be 5 quizzes, two exams and a
final. The 5 quizzes will be
unannounced. The lowest quiz grade will
be excluded. Quiz questions will closely follow homework problems or parts of
homework problems. All exams and quizzes
are open book, closed notes and closed homework.
A design problems will be assigned. The design problem will be graded according
to the results achieved.
Course notes for the coming week will be
posed on the course web site on Friday.
Homework is due on Tuesday in class or my
office before 4:00 pm. Homework after
this time will not be accepted. Homework
will not be graded but solutions will be posted on the course web site the day
after they are due.
Integrity Policy:
There is nothing more dishonorable for an
engineer, short of his work causing loss of life or property, than to present
the work of another as his own. This can
happen in patent applications, reports, presentations, and technical
papers. Dishonesty in course work is the
start of this slippery slope that ends in news stories such as we have seen
reported last year or worse. Pressure
may be felt in school however it is more difficult, not easier, to maintain
integrity in practice.
Presenting course work of another as your
own will result in a reduction in grade usually to an F.
