Requirement of communication

Regular communication is required of the student. This includes turning in assignments in a timely fashion and responding in a timely manner to feedback on these assignments. Any deviation of more than three days from the chosen schedule of the course must be approved in advance by the instructor. Exceptions will of course be made in the event of documented illness or other unexpected emergencies, but the instructor should be informed of such situations within a reasonable time of occurrence.

Getting Started in the Course

The Blackboard site for your course directs you to the Initial Information document and instructions for establishing communication, information on the nature of your course and the Orientation and Startup instructions you will need to understand and navigate the course.   This process will constitute appropriately the first week's assignments for your course (about the first half of the week during the shorter summer term), and will show you the basic navigation of the website including how to communicate, submit work, locate assignments and due dates, and more.

Text and Other Instructional Materials

The text is specified in Textbook Information, which the student will have encountered prior to arriving at this page.  Any student who has not noted Textbook Information is advised to review all information to be sure no other essential details have been missed.

Instructional methods

Students will complete and submit the assignments specified on the homepage.

The instructor will respond in a timely fashion to any work submitted, making suggestions where improvement is needed and posing questions designed to enhance the student's learning experience. The student will be required to respond to all critiques, except those designated otherwise.

Questions posed by students and the instructor's responses will be posted to a site, specified in at the beginning of the course, for the student's review.

Students may on occasion be asked to critique work done by other students.  Full student anonymity will be preserved, with no reference  to the identity of any party in this exchange.

The instructor is available via web forms (to which you will be introduced at the very beginning of the course), and will normally respond by the end of the day following your submission (and more typically on the same day) with answers to properly posed questions, feedback on your efforts, and other information. Exceptions may occur in the event of Internet problems or other technical events. 

Use of email:  Prior to registration and receipt of initial instructions students my use Email to communicate with the instructor.  However email is much less reliable than web forms, and after registration and receipt of initial instructions anything sent through email should first be sent using the appropriate form.

Grading policy

Five tests and will be administered, one over each chapter.

A student's portfolio, consisting of instructor responses to assigned work and/or daily quizzes, will at the end of the term be assigned a grade.  A student who completes all assigned work in the prescribed manner can expect to make an A on this aspect of the course. The average of grades assigned on this work will count as 1/4 of a test grade. If this average is higher than the average on other tests, it will be counted as 1/2 of a test grade.

Raw test scores will be normalized to the following scale, according to the difficulty of the test, as specified in advance of each test by the instructor:

A: 90 - 100

B: 80 - 90

C: 70 - 80

D: 60 - 70

F: Less than 60.

The final grade will be a weighted average according to the above guidelines. A summary of the weighting is as follows:

Test #1:  Weight .5 or 1.0, to the advantage of the student

Test #2: Weight 1.0

Test #3: Weight 1.0

Test #4: Weight 1.0

Test #5: Weight 1.0

Assignment/Quiz Grade Average: Weight .25 or .5, to the advantage of the student.

The table below summarized the calculation of course grades:

assessment weighting contribution to total score
test 1 1 test score * 1
test 2 1 test score * 1
test 3 1 test score * 1
test 4 1 test score * 1
test 5 1 test score * 1
portfolio 1/4 <= p_weight <= 1/2 portfolio score * p_weight
  total of weightings total of contributions

Final average = total of contributions / total of weightings

Criteria for Grading of Tests:

Tests will consist of problems designed to measure the level of your achievement of the course goals. 

Each problem is graded on a 10-point scale, with the following guidelines:
