Notes:

Overview:

• Lab.

Homework:

• A Check system.
• Check means "Mostly correct"
• Check plus means "Correct with some special characteristics"
• Plus means "Exceptional"
• Check minus means "Enough flaws to bother me"
• Minus means "Really bad, but something is correct"
• Zero means either "You didn't turn it in" or "So bad it's not worthy of a grade"
• Grades above check can be rare. (It depends on the assignments and the students.)
• How does this turn into a letter grade? With a 4 point scale.
• Tentative approach
• Check is a 3
• Check plus is a 4.5
• Plus is a 5.5
• Check Minus is a 2
• Minus is a 1
• Zero is a 0
• I then attempt the number to letter conversion
• If your average is 3.8 or better, you get an A
• If your average is 3.45 or better, you get an A-
• If your average is 3.2 or better, you get a B+
• If your average is 2.8 or better, you get a B.
• If your average is 2.45 or better, you get a B-.
• Etc.

Exams

• I use a variety of techniques for grading exams.
• Sometimes "Start at 100; each error is a reduction in points"
• Sometimes "N problems. N correct is an A. N-1 correct is a B. N-2 correct is a C. N-3 correct is a D. >0 correct is an F. 0 correct is a 0.

Participation

• Show up every day & answer questions & ask questions: 90

## Lab

• Do The lab.
• Be prepared to reflect.
