Big disaster, no class on Friday

Due to a disaster with my lower back, which is trying to assassinate me with muscle spasms, I must cancel lecture for today. No homework, either!

We will have regular lecture on Monday, Feb. 27. I will see you then and hand back your exam 2 printouts.

9, incredible!

WHOA!

It's incredible! I used nine of the student contributed questions on Exam 2. Usually, I only find one or two worth using.

Those bonus points are now UP in Webcourses.

Exam 2 scores are UP.

Except for a few students with papers out of the regular paperwork channel, your exam 2 scores are now up, in Webcourses.

The average was 24/40, kind of low, because there was a ton of students who scored 25/40, way more than the number who scored either 24/40 or 26/40. Unusual, but...

Tomorrow in lecture, we will have regular lecture PLUS hand out exam printouts.

The destiny of your brains

There are going to be a few real brain burners on Exam 2 and at least one of them will be in multiple choice.

I therefore predict that multiple crania will experience high temperatures at which human brains begin to fry. Just a theory.

That being the case, make sure to study HARD. Your other destiny must be to crush with impunity all midterm exams of Dr. B!

No office hour tomorrow

Due to a family obligation, I must cancel my Tuesday office hour tomorrow.

Homework 9

Your energy homework assignment, Homework 9, is now ready in Webcourses. It is due on Wednesday at 10:30 AM.

Bonus

Bonus point opportunity for Exam 2 is now open for business in Discussions. I posted an example of how to contribute a question.

GO for it!

Octopus on the run

I wonder if I can make a brain burner exam question with this video.

OK, good.

OK, the lecture podcast is now uploading. Everything back to normal.

Strange

For some reason, iTunes U is not letting me upload your Friday lecture. It's strange. I hope to get it up as soon as iTunes U stops being cranky.

No HW this weekend

No homework this weekend. I will see you all on Monday.

whooooops

Oh, man! I did it again. I did not get that potential energy assignment up for you by lunchtime.

I will put it together and set it up to be due on Friday morning.

This means that there will be two assignments due on Friday morning.

Excellent.

Homework 6 is running!

Your homework assignment #6 is now ready in Webcourses. Prepare your brain to be sizzled up to a crackly crunch by a few concepts brain burners and one calculations brain burner.

Big disaster

AAAAAKKKK!!!

Big disaster. I got sidetracked today by some non-academic disasterness (see photo), so I completely forgot to post your guys' homework.

So.... no homework tonight, but in lecture tomorrow I will get you ready for a good HW assignment for the weekend, with a good quantity of deluxe brain burners. For instance, which is heavier, a ton of bricks or a ton of homework? :D

See you in the morning, 10:30 AM sharp!

Exam blurbs

For those of you who've gotten your exam printouts, you can now correlate your incorrect questions to each question's general topic -- but not the verbatim question itself -- by looking at the blurb files, in Webcourses. Find it at the yellow pencil icon.

With the blurb file plus your exam printout, you can start building up a nice study guide for the final exam.

Exam 1 grades UP.

Your exam 1 scores are now up. The total is the sum of clicker and scantron performance:

   ..Exam 1 scantron
 + ..Exam 1 clicker
   ------------
     Exam 1

The average was about 72%. I normally do not assign letter grades on midterm exams, only on semester grades, but if I did, this average would be a C+. Not bad.

P.S. Some of you have no clicker data, so no score in that row. The actual data you sent is on a lower row of your My Grades page, as well as the sentence you coded.

Also, a few of you might not have scantron scores if your scantron did not get scored -- either by plan or because of a mistake on your PID. In either case, we will try to get that scantron score rounded up in the next day or so.

Squeeze

When you get to the BA119 lecture hall this morning, squeeze in to the middle of the row. Every single seat is going to be occupied.

Make sure your iClicker 2 is ready. I have a real brain-burner ready for you!
