CMPSCI 250: Introduction to Computation

David Mix Barrington and Hava Siegelmann

Fall, 2010

Course Requirements and Grading

Your grade in CMPSCI 250 will be based on the following:

• Midterm Exams (40%): There will be two midterm exams each counting 20% of your grade, on Wednesday 13 October and Tuesday 9 November, each 7-9 p.m. in a room yet to be chosen by the University. We will write an exam intended to be finished in an hour, and give you two hours to finish it. (Over the years students have accused Dave, at least of overestimating what they ought to be able to finish in an hour.) If we can we will make practice exams available before each midterm.
• Final Exam (25%):This will be during the December final exam period as scheduled by the University, and will be cumulative, though with greater emphasis on the last third of the course. You will have two hours. This exam will count for 25% of your final grade, except that we will count it for 50%, and reduce the weights of all other components proportionally, if this is to your advantage. We will make a practice exam for this if possible.
• Homework (25%): There will be six homework assignments during the term. Together they will count for 25% of your final grade, with the best five counting for 5% each. We may have some assignments, though not the first one, submitted by pairs or groups. Late homework will in general not be accepted -- we'll deal with valid excuses by giving "excused" grades on particular assignments.
• Discussions (10%): Attendance at the Tuesday discussion sections is required and this portion of the course grade will be based on your attendance and participation. In Dave's section, participation will be measured by group responses to in-class writing assignments, usually based on "Excursion" sections of the text. You will be divided randomly into groups of two or three and each group will hand in a response to the assignment. These will be graded "check" (B) or "check-plus" (A), and the best ten of your eleven will count for 10% of your total grade. Hava intends to handle this component somewhat differently.

Academic Honesty Policy

All work submitted must be your own in presentation. How much outside help is allowed depends on the course component.

• The exams are closed-book and no outside help is allowed. Any cheating on an exam is grounds for an F in the course.
• With homework the rule is a bit harder to specify. You may discuss homework with other students, in fact we encourage this as a learning experience. But again, the writeup must be your work. Copying is not allowed, and collaboration so close that it looks like copying is not allowed. (In general, if we get two identical homeworks we will accept neither of them (i.e., both get F's) and we will give you a stern warning that could lead to formal action the next time.) A good practice is to divide your work into an "ideas phase" where you collaborate and a "writeup phase" where you work alone -- enter the writeup phase with notes, but not written solutions.
• If you make use of a printed or on-line source for the homework, other than specific course materials such as the textbook or web site, please mention it in your writeup. Of course copying a solution to a problem from the web is cheating, and this is easier for us to detect than you might think.
