Introductory Logic Phil50

Spring, 2011

No credit will be given for late assignments.

Note that most homework is to be submitted for online grading. When you submit an assignment for the final time, you must indicate that I should receive a copy of the grade report (at my email address, However, if you wish you may submit one or more trial versions of the homework for online grading with grade reports to be sent only to you. Then you may attempt to correct any mistakes prior to the final online submission.  

I will accept only the first grade report I receive for a given assignment, however, so make certain that you have made all the changes you want to or have time for before you have a report sent to me!  When you submit an assignment with a grade report to be sent to me, make certain that you include all of the problems for that assignment in a single submission -- if you break up your submission into chunks, I will count only the first chunk.

Homework assignments are to be your own work. Submitting a copy of someone else's file is a violation of academic integrity.  Be aware that the grading software watches for this. (Discussing the homework assignments with other students and getting or giving general advice and suggestions is fine. Copying someone else's work is not.)

The schedule below is tentative; changes will probably be made as the semester progresses. Please consult the online schedule for the updated assignment.

Submit "You Try It," pp. 8-10 
Note: If you follow the step-by-step instructions in the book, you'll see in step 7 on p. 10 the instruction to select "Just Me" when submitting. Don't do this! Select "Instructor Too" when you submit so I can see you've done it (and so I can give you credit for an incredibly easy assignment).
