Entrepreneurship and Satan's Learning-Challenged Little Brother

Although most people know him as the creator of Dilbert, Scott Adams may also be one of the funniest writers around. Here's a recent piece that appeared in the Wall Street Journal Online where he talks about dissatisfaction as a major driver of entrepreneurship:
I wasn't suffering alone. Many of my co-workers already had active side businesses and ambitious expansion plans. The guy in the cubicle behind me was running a concert equipment rental business. Across from me was a guy running a computer tech support business. We had Amway dealers, Mary Kay sales people, inventors, authors and just about any other business you can imagine. That's not counting all of the business plans in the incubation phase. I think we all understood that working in a cubicle and being managed by Satan's learning-challenged little brother was not a recipe for happiness.
Actually, it was a hamster-brained sociopath of a boss that made me think about going into academia.

Read the whole thing here. - it's good for a laugh (and it makes a lot of good points, too).

The Fun of The Exam Continues

It seems like every semester, I get at least one student who bombs an exam (or two) and reacts in a way-over-the-top manner. Last semester, it was a senior finance major (with a pretty high GPA) who suffered from anxiety attacks. She drew a complete blank during my Advanced Corporate Finance midterm. She subsequently appeared in several professors' offices wondering tearfully if she should change her major in her senior year. We eventually talked her down off the ledge, and she even subsequently took my Student-Managed Investment Fund class, where she did just fine.

But this semester took the grand prize. The 80/20 rule says that 20% of your students cause 80% of your problems. That would be true this semester if you counted ONE student alone as my 80%. She (we'll call her Brittany henceforth) is to put it succinctly, a bit of a Princess - high maintenance, dressed entirely in designer clothes, vocal, bossy to her friends, and simply not doing well in the class. BP informed me two weeks into the class that she's taking 18 (or is it 20) credits this semester because she needs to graduate this spring. So she "really really really needs to pass this class." She constantly whines in class about the workload because she has soooo much on her plate, and complains about any thing that doesn't pass her standards (by which she means, anything that she doesn't understand easily). And nothing is ever her fault.

Her first exam grad was a 55. The most recent exam (the second of four) was a 58. The rest of the class seems to be getting it -- in fact, as I recently posted, the class average was one of the highest I've seen on this exam in about ten years of teaching. The class has really respodned to the challenge - they've not only stepped up their game, they seem to have realized that complaining to me about the workload is like trying to teach a pig how to sing (i.e. they expend effort, accomplish nothing, and both they and the pig (that's me) get annoyed). Except for Brittany the Princess - she's used to getting her way with whining and intimidation, so she keeps trying.

After she got her exam back, (it was handed back Monday - the drop deadline for the class), she came to my office wondering if she should stay or drop. She wanted assurances that if she was "close", I'd give her the minimum passing grade (since it's required, all she needs is a D-). Unfortunately, I couldn't give her any such assurances - I said that I often make the cutoff for the various grades somewhat lower than what's in the syllabus, but that's done on a case by case basis after looking at the overall class performance, and that whether or not she should stay in the class is a decision that only she could make. So far, there's nothing new to the story - pretty much standard stuff we've all seen many times.

Then the fun started.

BP goes out into the hall and starts sobbing and wailing. That's right, wailing. You could hear her almost on the other side of the building. Of course, I stay safely in my office - there's no way on God's Green Earth I'm going out to deal with that, because there are (like Bear Bryant said about passing the football) only a few things that can happen, and most of them are bad. Luckily, one of the female staff from one of our institutes came out and said "honey, why don't you go into that empty classroom so that you'll have some privacy" (read: "so that you won't be such a spectacle"). The staff worker said that she figured that the student in question was used to using the "cry out loud and maybe you'll get what you want" card. Shortly thereafter, several of her classmates (the ones who she hangs with) came in to my office and said "don't worry about Brittany, UP - she'll be fine. She does this to get attention and to see if she can get you to give her what she wants).

Unfortunately for my blood pressure, she decided not to drop the class.

Ah well - another day in academia. At least I'll have more Brittany stories to share as the semester progresses.

The Unknown Students Nail an Exam

I've been teaching the undergraduate core finance class this semester, . If you've been teaching for a while, you know that it's easy in that class to get discouraged by students who are (pick any or all that apply) unmotivated, unable to do simple math, whiny, unwilling to be stretched, never darken your office doorway, etc...

This semester, I made a conscious decision to really push my students - since the first week of September, they've two exams, three very involved problem sets (with a lot of curves thrown in - the typical one takes about 3-5 hours to complete), eight online quizzes, and short pop quizzes (they typically last 5 minutes or less and contain 1 or 2 basic questions on the material to be covered for the day's class) on average every other day, and almost constant cold-calling in class (in a 50 minute class, I typically call on 15-20 students). I like to think that I've set the bar at a far higher level than the other sections of the intro class being taught this semester. In fact, some of my students have told me that I've brought the class together - they're getting together in study groups of as many as 10 at a time (and there was supposedly a study group the night before the first exam of almost twenty students).

I've also made a decision to teach in full-blown crazy mode. Those who've heard my bloviations over the years know that I'm a flaming extrovert that tends toward (in my better moments) impressions of Ahnuld (I Am The Denominator!), Mister Rogers, Kermit The Frog, Inigo Montoya, and various characters from the Simpsons, South Park, and Monty Python, often in rapid succession. The last few years, the Unknown Son's illness had really taken a toll on my zest for teaching (and it showed in my evaluations). While he passed away almost 18 months ago, it's only been this semester that I've really felt like the "old" me. So, teaching has been a real pleasure.

Well, my class just had their second exam, and to put it bluntly, they did more damage to the exam than the Republicans did to the Democrats in the last election - they knocked it out of the park. There was the usual variation in grades, of course (one student got a 23 - It's never when your grade approximates your age), but on the whole they performed better than any comparable class I can remember going back to the late 1990's.

So, there is hope. It's nice to see that when you set the bar high (and meet the students more than halfway), they respond to the challenge.

Terry Pratchett Quotes

Before J.K. Rowland, Terry Pratchett was the best-selling British fantasy author of the 1990s. He's written more than 60 books (either by himself or in collaboration with a coauthor). In fact, while I was at the recent FMA conference I made a comment "There can only be... one thousand" at a reception,a and found that an Irish friend of mine was a fellow Pratchett-phile.

So imagine my enjoyment at finding out there's a repository of Pratchett quotes titled the Pratchett Quote File (you can also get it in a test file here). Here's one that struck home (note that the Unknown Wife and I just celebrated our 20th anniversary):
Sam Vimes could parallel process. Most husbands can. They learn to follow
their own line of thought while at the same time listening to what their
wives say. And the listening is important, because at any time they could
be challenged and must be ready to quote the last sentence in full. A vital
additional skill is being able to scan the dialogue for telltale phrases
such as "and they can deliver it tomorrow" or "so I've invited them for
dinner?" or "they can do it in blue, really quite cheaply."
-- (Terry Pratchett, The Fifth Elephant)
Unfortunately, skimming through the quote file just burned an hour and a half of my time. I guess I really don't want to start grading the 70 exams currently sitting on my desk (each of which has 10 pages of work in it). Unfortunately, I just gave the exam tonight, and I want to give them back on Wednesday (it's the drop date for the semester).

Irony

I regularly get together with a couple of guys from my church. We've been going over a book titled "Twelve Steps for Recovering Pharisees". It's main theme is that we are pretty much all hard-wired to find ways be judgmental twerps who try to make ourselves feel superior to those around us. So this cartoon from XKCD hit the spot.

I Don't Seem To Have a Lot of Empathy

I just took an empathy test (the Baron-Cohen Empathy test) - I scored a 23. A high-functioning Autistic or someone with Aspergers typically scores about a 20. Maybe my wife is right, and I am simply not that empathetic. However, she could have been kidding (if so, how would I know?).

New Video on Time Value

As I mentioned before, I've been doing a bit of work with screen recording software. Previously, I'd done a 4-video series on how to use the BA 2+ calculator. Well, I'm at it again.

This semester, I'm teaching the undergraduate core finance. I plan on making a series of videos on the main topics that I can then use in upper-level courses. That way, I can eliminate the need to take valuable class time for going over prior material. Instead, if the students feel the need for a review on (for example) Effective Annual Rates, they can simply watch the video. Eventually, I hope to have a library of videos on many of the major topics we cover in the intro course.

Here's the first one - on the basics of Time Value. This one covers problems and concepts related to Present/Future Values of single lump sums. If you find it helpful, let me know.

You can see my other videos at the following site - the BUS424 folder contains a number of lectures I made for my Fixed Income class. Feel free to use and share them.
