-----------------------------------------------TESTS (60%)– There will be three tests. There will be two in-class tests. The final
test will be given at the time assigned by the university for final exams. All students
will take the final at this time unless specifically arranged with the instructor. Each
test is worth 20%.
HOMEWORK ASSIGNMENTS (25%) – There will be homework assignments
reviewing concepts discussed in class. These assignments will include computations,
problems, and presentation, review, and discussion of journal papers. Homework
assignments are sometimes assigned in conjunction with weekly assignments of the
laboratory portion of the class.
Grading – Typically, I assign grades on a curve. I award grades of “excellent” to
students whose performance is in the highest category of students who take the
class, averaged over the last several years. Typically, a few students earn this grade
each year. Many students earn grades of “good”. Relatively few students typically
earn grades of “average” or “poor.”
FINAL PAPER (6150: 15%)-- Those students taking the class as 6150 are taking the
class for graduate credit. Each of those students will write and prepare a 5-page
literature review paper for a topic in fluvial geomorphology of relevance to their
graduate research. The topic of this paper is to be approved by me by October 15.
No less than 10 individual papers, or references, are to be assessed in the writing of
this paper.
For those undergraduate students who enroll in 5150, the unassigned part of your
grade (15%) will be assigned based on your class participation.
