Position Paper #3 Grading Rubric	              Version: 14 Mar 10
========================================================================
I. VALIDITY OF ARGUMENTS:

 1.  Argument 1,2,3/.'. 4:	valid? + reason

	0 = no answer
	1 = answer, no reason
		    OR reason that confuses definitions
			of 'valid'/'invalid'/'sound'
	2 = answer, weak reason
	3 = answer, good reason

------------------------------------------------------------------------

 2.  Argument 1,2,5/.'. 6:	valid? + reason		0,1,2,3 as above

------------------------------------------------------------------------

 3.  Argument 4,6/.'. 7:	valid? + reason		0,1,2,3 as above

------------------------------------------------------------------------

II.  TRUTH VALUES OF STATEMENTS:

 4.  Prem 1:	agree? + why?			0,1,2,3 as above

 5.  Prem 2:	agree? + why?			0,1,2,3

 6.  Prem 3:	agree? + why?			0,1,2,3

 7.  Conc 4:	agree? + why?			0,1,2,3

 8.  Prem 5:	agree? + why?			0,1,2,3

 9.  Conc 6:	agree? + why?			0,1,2,3

10.  Conc 7:	agree? + why?			0,1,2,3

========================================================================

The total is 30 points, which, following my grading theory, maps into
letter grades as follows:

letter	CSE484		both	CSE/PHI584

  A			29-30
  A-			27-28
  B+			 26
  B			24-25
  B-			22-23
  C+			 21
  C	17-20			11-20
  C-	14-16
  D+	11-13
  D			6-10
  F			0-5	

------------------------------------------------------------------------

As usual, on my grading scheme,

	"A" means "understood the material for all practical purposes",
		(here, that's 30 pts = 10 questions * 3 pts full credit)

	"B" has no direct interpretation,
	    but comes about when averaging grades of A and C

	"C" means "average",
		(here, that's 20 pts = 10 * 2 pts partial credit)

	"D" means "did not understand the material,
		(here, that's 10 pts = 10 * 1 pt minimum credit)

	"F" usually means "did not do the work" (i.e., 0 pts),
	    but can also come about when averaging Ds and Fs.

for the theory behind all of this, which I'm happy to discuss via
UBLearns email.
