This will end badly, part 2

May 17th, 2007

I haven’t had much time for posting recently, but there was at least one news item that caught my eye today. A little while ago, I posted about Georgia wanting to offer Bible classes in their public schools, saying that

Even if all the students are Christians, teachers run the risk of running afoul of the ways different sects of Christianity interpret parts of the Bible. (one example: Biblical literalists vs. old-Earth creationists). Add in complaints from the sprinkling of kids who have non-Christian parents, and you’ve got a recipe for nothing but trouble.

Some districts in Texas do offer Bible courses. How’s that working out for them?

Two advocacy groups filed a federal lawsuit Wednesday against a West Texas school district on behalf of eight parents who say a Bible course violates their religious liberty.

[…]

“Religion is very important in my family and we are very involved in our religious community. But the public schools are no place for religious indoctrination that promotes certain beliefs that not all the kids in the school share,” Doug Hildebrand, a Presbyterian deacon who is among the plaintiffs, […]

Georgia, meet your future.

Relieve the pressure of the burdens on your house!

May 12th, 2007

Here’s an interesting concept. For a fee, these kind folks will come toss bundles of straw onto your house.

[House wasing]

I hear that it relieves stress on the roof.


Wase \Wase\ (w[=a]s), n. [Cf. Sw. vase a sheaf.]
– A bundle of straw, or other material, to relieve the pressure of burdens carried upon the head. [Prov. Eng.] –Halliwell. [1913 Webster]

Grading in the Twilight Zone

May 11th, 2007

By now, you’ve probably seen this example of student “reasoning” on the internet somewhere.

[Find x - here it is!]

I don’t believe that one was actual student work. Clever and amusing, but not real.

Real examples of bizarre student work look more like what you’re about to see. This is one student’s “scratch work” – for which he presumably intends to obtain some sort of partial credit. This is all of his scratch work from the entire test.

[Scratch work]

Welcome to the Twilight Zone of grading. How many points do you think this student’s effort is worth? (You can probably guess how good this student’s actual answers were.)


Just so you know, I didn’t mistakenly give a chemistry lab exam to a second grader. I do teach only adults in my classes.

And no, there were no questions that related to butterflies, dogs, or pigs.

Friday cat: Department of Home Security

May 11th, 2007

The neighbors have gotten a new puppy. As a result, their cat Patches has been spending a lot more time in our yard. To protect against this threat, our cats have created the Department of Home Security. Its members are on tireless watch to prevent foreign felines from entering the territory of the United Cats of Shrimp and Grits:

[Tom and Ash protect the homeland]
DHS Agent Tom and DHS Agent Ash protect the homeland!

Since the Department of Home Security was founded, not a single foreign cat has wreaked havoc inside the house. Now if only something could be done about the havoc that the Department wreaks on its own…

It’s the end of the semester, and I haven’t been properly updating the blog. But here, without further delay, is this week’s Friday Cate:

Honest, officer! I only had one bottle!

Cate’s recently learned that she can rotate her walker around and move in different directions. She seems happy about it, too!

This will end badly

May 2nd, 2007

CNN has reported that Georgia has approved state sponsorship of Bible classes in schools. Why? Here are a few opinions from supporters of the idea.

“I don’t think you can understand Shakespeare, that you can understand a great deal of literary allusions or that you can understand a great deal of Western civilization without understanding the role of the Bible,”

[…]

“It’s going to challenge the faith of some students and it may foster the faith of others,”

Georgia hopes to skirt the obvious Constitutional problems with these classes by saying that

The classes must be taught “in an objective and nondevotional manner with no attempt made to indoctrinate students.”

My take? This will end badly. Teaching a Bible class to a set of students with diverse religious backgrounds without some of them (or their parents) seeing the class as a form of indoctrination will be impossible. Even if all the students are Christians, teachers run the risk of running afoul of the ways different sects of Christianity interpret parts of the Bible. (one example: Biblical literalists vs. old-Earth creationists). Add in complaints from the sprinkling of kids who have non-Christian parents, and you’ve got a recipe for nothing but trouble.

The schools will bail once they get slapped with enough complaints and lawsuits over the classes. This will occur only after a lot of taxpayer money is wasted on the whole process.


Having said all that, I actually do believe that knowledge of the Bible is helpful. (A great way to lead someone away from the path of fundamentalism is to have them actually read that book they’re being so fundamental about – all of it – and to learn about the history of that book.) But, I just don’t think that it’s possible in our current social environment to have Bible classes in public schools that don’t “indoctrinate” in some way. We have enough of a time keeping religious indoctrination out of biology classes. How the heck would we keep it out of a Bible class?

A little earbud told me

April 30th, 2007

There’s an article up on CNN about a new fad for cheaters – cheating via iPod.

Some students use iPod-compatible voice recorders to record test answers in advance and them play them back, 16-year-old Mountain View junior Damir Bazdar said.

This suggests to me that some of these classes might have other problems than iPods. How did these kids got “the answers” to record?

Others download crib notes onto the music players and hide them in the “lyrics” text files.

This is actually somewhat clever. It’s the twenty-first century equivalent to hiding notes as formulas in programmable calculators – a practice which goes back at least twenty years.

The solution to this particular problem is pretty obvious, though. As we do with cell phones, we simply disallow the use of iPods during tests. In most classes, the iPod would have any legitimate use during a test! Of course, some students are not happy with such policies:

Kelsey Nelson, a 17-year-old senior at the school, said she used to listen to music after completing her tests — something she can no longer do since the ban. Still, she said, the ban has not stopped some students from using the devices.

To that I’d simply say … Kelsey, blame the students who decided to use their iPods to cheat. Were it not for them, you could still listen to your music. Of course, the school could modify the policy to state that iPods were allowed after a test had been turned in.

“You can just thread the earbud up your sleeve and then hold it to your ear like you’re resting your head on your hand,” Nelson said. “I think you should still be able to use iPods. People who are going to cheat are still going to cheat, with or without them.”

Sure, some people are going to cheat no matter what***. Banning iPods during testing, though, has two points:

  1. To make it a little more difficult to cheat. There are a substantial number of people out there who would be tempted to cheat instead of study if cheating was very easy to do. Those are the ones we are trying to prevent from cheating. The hard-core cheaters … well, those we just have to catch and get rid of****.
  2. To make it easier to bust cheaters who try to hide their cheating devices. All we’ve gotta do with a no-iPods policy in place is show that the cheater had an iPod out during a test. Otherwise, it’s much more hassle to get a cheating accusation to stick – since it would require us to find out exactly how the student hid the information on the iPod.

Despite iPods being all the rage, here at the college the old ways of cheating seem to be the most common ways. Notes written on a desk or body part, small pieces of paper pushed up the sleeve, a strategically placed scrap of notes on the floor … all of these are still in common use. Even formulas in calculators pop up occasionally – though this seems a little less common these days. Most of my students view their TI-99 calculator much like someone of my generation would have viewed a slide rule. (I can’t tell you how many students I’ve had to teach to do simple math functions on their TI!) I guess the iPods and cell phones are easier to use!


***These folks almost always have terrible grades – at least in college where I encounter them.****Sound harsh? The hard-core cheaters often brag about it to other students, lowering the morale of the entire class.

Why the numbers matter

April 30th, 2007

My introductory chemistry class is geared primarily towards students who are getting their associate’s degree in a medical field – mainly nursing. Because of this, we use drug dosage calculations for math practice when we discuss metric unit conversions.

Some students think I’m harsh when I don’t give credit for botched drug calculations. I, of course, disagree – and Abel Pharmboy’s found a news item that illustrates why:

A pharmacy erroneously made a drug 10 times more potent than intended, which killed three people who received it at an Oregon clinic, the state medical examiner said Friday.

if any of my students are reading this, take note. Stupid math mistakes are sometimes amusing, but never when someone’s life is at stake!
