Instructions for graders

I'm glad that you're grading for me.

All assignments will be on the web: Go to my home page www.mtholyoke.edu/~adurfee, click on "Courses" and at the top of the page click on the "daily schedule" of our course. This will be updated on a regular basis. All assignments are due at 5 pm on the given day (I interpret this loosely). Pick up the assignments in the envelope on my bulletin board. Return them in a few days to the other envelope.

I will give you a class list. Assignments will be numbered. Some problems will be from the book. Other problems will be given in class.

Basically give three points for each problem, or part of each problem. (This is not a fixed rule and you can change it as you see fit.) Keep a record of the number of points each student gets on each assignment. Also keep the records of a fictional student called "Max" who always gets perfect scores. The common way to keep records is to use a spreadsheet like Excel.

The students are allowed to rewrite each assignment. In this case, if they do something wrong on the first version, or don't know what to do, write some helpful hints on the original and send it back. They are supposed to hand in the revised version a few days after they get their original back. Grade it and replace the original score by the score on the rewrite. They can rewrite the rewrites. If this forms an infinite sequence hopefully it converges.

Around mid-semester please email me the excel spreadsheet, or send me a paper copy of the grades.

At the end of the semester please add up the total score for each student. Then scale the score for each student: Let M be the total score for the fictional student Max. Multiply the total score for each student by 100/M. Now the homework score for each student is rescaled to something between 0 and 100. Then email me a copy of your spreadsheet.

Thanks!
