How to earn extra points in PSCH 343 Lecture
(applies only to PSCH 343 classes in which Dr. Levine is the lecturer)
If, during the lecture, a mistake is made (as sometimes does happen), the person who points it out during the lecture will receive one extra credit point. That's equivalent to one more question correct on the final. Finding really grievous errors will be worth two points.
Rules:
1. The point (or two) goes to the first person to notice and correct the error.
2. It must be a "real" error. That is, something like an incorrect sign, a missing term in an equation, using the wrong data to plug into a problem, etc.
3. It is not a "real error if the notation is different from that in the book, or if a different symbol is used for a variable than was used in a previous problem or derivation. However, mixing up the symbols for sample versus population statistics does count as an error.
4. I will occasionally make a deliberate one-point error to offer the chance for extra points. If no one catches these errors in a short time, I will correct myself (but not collect a point!).
5. My decision about whether a correction is worth one point or two (or any) is final.
Rationale:
Some errors are genuine slips -- catching these as early as possible will prevent having to backtrack later in the class. But the main reason for this is to encourage students to attend classes and pay attention. I am constantly amazed by students who complain after the final that they didn't think this sort of thing would be on it, or that it was too hard (when I had done many of the same problems for the class in lecture), when the problem is they missed a significant number of classes.
