Partial credit in your future

I majorly like the partial credit possibilities here, with SMA mode, and I hope you realize the advantage it holds for you as a student taking the examinations.

Partial credit is a feature in long hand-written exams in upper level physics courses, which have to be graded by hand by professor and TAs. It is very laborious to grade but the results are important to assessing a student's understanding. I can now make these distinctions with you guys in GEP physical science, using SMA and analyzing the results.

So your class just went into overdrive.

Scores are UP for midterm 2, including all SMA (regular and bonus)

OK, all the exam points are graded and IN. Look at your My Grades page for the breakdown: total score, SMA scores

1. "Midterm exam 2" = all points together, scantron + SMA regular + SMA bonus
2. "....subscore - Midterm exam 2 SMA regular (2)" = points from questions 49 and 50.
3. Down the page a bit, "Exam 2 SMA bonus (4)" = score on questions 51 and 52, including partial credit.
4. "MOK on 52?" is a comment line to indicate whether you earned partial credit on question 52.

ABOUT PARTIAL CREDIT:
Questions 51 and 52 were linked together, so that the result from 51 was required for 52. This being the case, it was possible to halfway mess up: wrong answer from 51 applied correctly in 52. I can analyze your data to detect this.

• When I saw that you attempted the correct method on 52 with incorrect numbers from 51, I wrote down the symbol MOK, meaning "Method OK." This is in the "MOK on 52?" line of your My Grades page.
• If you got both questions right, I inserted"All OK", and
• if you did not answer or answered both incorrectly, I inserted the word "no."

To give partial credit, I needed at least one point to award, which meant I had to make questions 51 and 52 worth 2 points each, partial credit 1 point possible on 52. So you received either 4 points for "All OK," or 1 point for "MOK" on 52, or zero bonus points. It was a tough pair of questions.

I have scores

I have your exam 2 scores from test scoring. I have to put them together now with your SMA pointage, regular and bonus. Still some work, but maybe sometime tomorrow you will see exam scores. Hang in there.

Amazing

I just figured out that I can analyze your SMA input (inside Excel spreadsheet) for partial credit. E.g., if you make an error on #51 but then use that answer with the correct method in #52, I can give partial credit on #52.

Incredibly sweet. You cannot underestimate how exciting that is for me. It means that, as we build up the SMA part of the midterms, we can extract partial credit, maybe even bonus points, from the input. It is like going from a tapping a spoon on a bottle to listening to a symphony orchestra.

Excellent!

Exam 2 in the pipeline

Your exam scantrons are in the pipeline, and when they get done and returned to me, I have no way of knowing.

So do NOT send me course mail messages about when the test scores will be in.

Do not send me AIM or call me on the phone about test scores.

Do not get Ashton, Meg or Gaby to ask me about exam scores.

Failure to comply will earn you a five yard penalty, illegal procedure.

Just wait, and keep your eyes here. 30 seconds after I upload grades into Webcourses, I will post an announcement here. So this Blogspot is the place to seek your answer.

Thank you and have a nice day.

In case you are looking for me tonight, you will not reach me...I will be off the air, working on your midterm for tomorrow morning.

Expect the unexpected.

In the meantime, make sure to pepper Ashton Dacus, Meg Averil and Gaby with questions in Webcourses! They'll be my deputies tonight!

New blurb file about work and kinetic energy

I just created a new lecture file, with some extra emphasis on the spatial relationship between force and displacement vector. It amplifies and reinforces some of the ideas we discussed in lecture on Tuesday. Take a look in the Lecture Files.

Office hours today

I will have office hours to study today, 8:00-9:45 AM and 2:45 - 4:15 PM, in Starbuck's in the UCF Bookstore in center campus.

HW 10 is UP

OK, last homework before the midterm is now UP. Sorry, it is a bit later than usual. It is HW 10, with a few brain burners in there on kinetic energy and work.

Gaby guides and CPS points will be up tomorrow morning. Good night.

Voting

Dont forget to vote today and tomorrow in campus issues like Green Campaign etc. The destiny of the free world does not depend upon it, but vote anyway. :)
