Recording and transcript ready now.

The office hours session tonight was excellent. You can view the recording of it now, plus read the transcript. Check the "Offiec hours: recordings, transcripts" page on Webcourses2!

Good night!

Office hours for getting ready to C R U S H Friday's Exam 3.

I just scheduled two new office hours sessions this week:

1. Wednesday 9:00 - 10:30 PM, and
2. Thursday 9:00 - 10:30 PM

to prep for Exam 3 on Friday. Prepare a question or two, because in office hours YOU have the agenda.

Last learning modules are now UP.

The last three learning modules for Summer B are now available in Webcourses2. Two will earn you 4 regular participation points each, but the last one, O for Oceans, will earn you 4 bonus points if you make the Friday deadline.

Nice.

So get ready to push, finish the last lap with power and crush Exam 3 on Friday!

New mini-podcast on concentrations and solutions

I just published a new mini-podcast about concentrations and solutions, going over some concepts from chapter 11, pp. 280-283.

By the way: To view the artwork track of audio files in iTunes 11, you must Command-click the small square icon left of the progress bar. That will pop out the diagrams, formulas and notes embedded in the artwork track. You can make it full screen, very nice.

Modules are UP for the coming week.

Deeper into the study of molecules and atoms:

1. Learning Module H, on chemical bonding
2. Learning Module I, on solutions

The due date for the mini-quiz of each module is this coming Friday, July 26, at 5 PM.

Grades state, as of July 20.

Here is the state of grades, in the form of a histogram, for the entire online section as of this morning.

It includes regular points (mini-quiz participation and exams) plus bonus points for those who've earned them. Also, it shows all but a handful of students who did not take one of the exams: either Exam 1, Exam 2 or both.

TONS of students getting B, almost as many looking at a C, but just a few are taking down an A.

All this is preliminary, and will change in the next two weeks, as we complete five more learning modules and Exam 3.

Subtotals

I just set up a pair of subtotals related to your semester grade, viz.

1. "Semester points subtotal, July 20" for participation points and exam scores, out of 128 points possible as of July 20; these are the regular pointage activities on the syllabus.
2. "Bonus points subtotal" -- if you have earned any!

On the Exam 2 question bonus points opportunity, I awarded five students a bonus point for theor questions I used on the exam.

To estimate your grade status as of today, add up (i) and (ii), divide that sum by 128 to get your current percentage, then use this table

A	0.90 or more
B	0.75
C	0.60
D	0.50
F	below 0.50

Of course, your subtotals will change as we proceed through the next two weeks to complete Summer B.

Exam 2 closing in a few min.

Exam 2 availability is just about done, a handful night owls still working on it.

Right now it looks like the avg. score was 34.07 out of 48, which is about a 71%, about 5% higher than the Exam 1 avg. Good!

Office hours, good session!

We had an excellent online office hours session tonight, going over some of the chapter 8 questions from mini-quiz G plus the brain burner again from mini-quiz F.

The transcript and recording are now available. Look for the "Office hours: recordings, transcripts" page on Webcourses2.

Two office hours sessions, one late, one early

I will be holding two office hours sessions tomorrow and Wednesday, one late and one early in the day.

1. Tuesday evening office hours, 07/16/2013 9:00 - 10:30 PM
2. Early bird office hours, 07/17/2013 7:30 - 9:00 AM

Mini-quiz E duplicate

I accidentally duplicated mini-quiz E last week. You can ignore the duplicate, and I will leave the original version open a few more days, for safety. There are a few of you who only took the duplicate: no worries, I will square away the participation 4 points for you, but you can study with the original version.

Two new modules ready to go

The two new learning modules for this week:

6. Module F on chapter 6, electromagnetic field, and
7. Module G on atoms and the periodic table, chapter 8.

There is a special "battlefield version" of mini-quiz F for you to try out prior to the exam on Friday.

Office hours right now!

I am holding online office hours right now in UCF Adobe Connect. The link is in our Webcourses2 area, in the right sidebar.

Mini-quiz F, "Battlefield version"

I have just set up a "battlefield" version of mini-quiz F for next week's module F. It is meant to simulate "battlefield conditions" of a regular midterm exam:

1. Fast pace: avg. one minute per question
2. one question at a time

Use the regular mini-quiz F for leisurely studying. Use the battlefield version for testing your computer and ISP, to make sure that everything works well. Please be super paranoid about this: If it loads slowly, find another computer or internet service that runs fast and smooth.

New podcast for chapter 5 concepts

I just completed a new podcast, related to chapter 5, Fig. 5.2, a spring oscillator system. It is uploading to our iTunes U area right now.

Bonus points posted

I just finished typing in the bonus points for five students who contributed questions for Exam 1 which were such good questions that I had to use them on the actual exam. You may have recognized the questions.

For those of you who contributed but did not get bonus pointage,

1. it might be because it was wrong, or
2. because it was too simple, or
3. because it was too close a copy of one my mini-quiz questions, but
4. it might have been a good question that needed revision but you did not follow up after my comment for revision!

We will have similar bonus point opportunities for Exam 2 and Exam 3. Be ready to grab that bonus and GO! GO! GO!

Learning modules E and E2 are now ready.

You can now start studying the concepts in learning modules E and E2. Their mini-quiz deadlines are this coming Friday, July 12, 5:00 PM.

Exam 1 is running now.

Exam 1 is running now, with already a few students in there taking it.

Complete it before 11:59 PM tonight.

Next modules will be activated Saturday morning.

Office hours Wednesday evening (tonight)

I will hold online office hours for general discussion tonight, 9:00 - 10:30 PM. This is the last chance for office hours consultation before Exam 1, which you must complete between 10:05 AM and 11:59 PM on Friday, July 5 (this Friday!).

Postpone office hours to 9:00 PM tonight

Due to an NBA-related emergency, I have to postpone my online office hours until 9 PM tonight. We will go from 9:00 - 10:30 PM. See you then!
