It's That Time Of The Year

Yes, I've not been posting much lately on LiveJournal/Dreamwidth. Hell, I haven't been posting much on Facebook, either.

The reason, of course, is that it's the end of Fall semester. Final Exams were last week, the last week of class rush the week before. And now it's Grading Week, that abbreviated period that ends with the Death Clock running out Tuesday at Noon. (grin)

So I haven't given up on blogging. I'm not ignoring you. I'm just up to my armpits in grading papers.

As Grade-a-Thon Continues...

I find myself about two-thirds through the Topic 1 Science Literacy Book Report papers. I was struck by the reason one student gave for reading Frankenstein. As an older title, it was available as a free e-book.

A lot of students choose their books based on which titles are left to check out from the WMU Waldo Library, again for free. A few bum the books off of friends and family. Sometimes there's a book sitting on their shelves which they've "been meaning to read" for a number of years.

And while I wouldn't advocate theft, free books are good.

But what struck me is this is the first definite example of someone reading an e-book, as opposed to hardcover, trade, paperback or audio book. Frankly I've been expecting people to say they've read them electronically, on iPod, iPad, iPhone, Kindle, Nook, Sony, laptop or what have you. But this is the first one.

And then they didn't mention the platform. (grin)

Perhaps next semester I'll do a survey about where they got their books.

On The Other Hand...

Disappointed with many of the Topic 2 Worksheets whereupon the students use their car to take real world data and then analyze it. I'd warned them once that Physics pedagogy research shows that many Physics students believe one thing in the classroom and then forget it outside. And the lousy use of calculations, significant figures and just wrong application of Physics equations and variables afflicted maybe half the class.

And yet as a class they did outstanding work on their Final Exam, taken the day after they turned in their worksheets. I guess it is true -- Physics doesn't apply to the real world. (NOT)

Sigh.

Happy Canada Day!

It's July 1st and that begins a whole month of national holidays.

As For June... And May...

Oh yeah, I've been teaching. (grin) Teaching in the summer is like driving a race car instead of a suburban commute. All the material, half the time, half the weekends, all the quizzes -- every day in fact -- and it's a whirlwind.

So as for why I've been scarcer on LJ than I'd like, well, now you know. Of course this is now officially Grading Weekend. Because Tuesday was the Final Exam and yesterday, Thursday, I got the finals back from the grader. So we're down to grading two-and-a-half quizzes, the Topic 1 Science Literacy Book Reports and the Topic 2 Real World Driving Data Worksheets. Good news? Only 37 in the class.

But I Am Behind

Had composed a number of LJ posts in my head while driving to/fro K-zoo, but of course that doesn't count. Not until we get John Scalzi's BrainPals installed.

So... later.

The End

Monday

Drove into the office on Monday of Grading Week. Though the university will close between Christmas and New Year's and they are threatening very cold temps in the buildings with the new thermostat controls in place, it was surprisingly warm in my office. Yay. I've had years when I was waiting for the grader and it was too cold to think, write or type.

Actually, before I got to the office I stopped at the WMU Parking Office to get a new parking sticker. Yeah, as a part-timer I have to get one of these every semester. Except... the clerk was having trouble getting the right menu item and so snagged a passing uniformed Public Safety officer. Turns out as part of the new part-time instructors union, I get to have a regular parking hang tag. Yay! Actually, it's a GH grad student tag -- the contract was accepted too late for Public Safety to make part-timer hang tags for 2010-2011. But this will be really handy, especially on days when I have to drive a different vehicle.

Meanwhile, my erstwhile grader managed to get the final exams and quizzes 18, 19, 20, 21 and 22 into my mailbox. Triple-Yay! Nothing like having the papers back and not gnawing the insides of my cheeks waiting for the grader to show, and also inputting the scores and not having to drag papers home. And have them cluttering the house until January.

Monday Night

I had one old pesky quiz to grade, then curve the final, massage the grades. And found myself ready to input the final grades at 11pm. Usually on a school night we'd be tucking in the kitties downstairs, but with vacations looming, I started right in. Later in the night I posted the grade breakdowns on the class webpage. By the time I went to bed I was totally done for my Fall 2010 class. And it wasn't even 11:58am on Tuesday!!! (grin)

Tuesday

Play! I'm off now. Mrs. Dr. Phil is on vacation this week. So we headed off to Celebration Cinema North to see Tron Legacy in IMAX 3D and Harry Potter 7.1. Reviews coming, but it was a fun afternoon.

Now... writing to do.

Grading Continues

My exam grader has informed me via email that the Finals and the last quizzes are now graded -- I'll get them Monday. Yay! That's one nagging worry I can forget about for a while. Sometimes I don't hear from graders for a lo-ong time and it makes me very, very nervous. The hard deadline is Noon on Tuesday -- that's when they shut down the online grading system to start processing Fall semester grading.

And On To Spring 2011 Semester News

Back during the summer, my boss told me he didn't have any classes for me for the fall, but I'd have two sections of the first semester Physics for scientists and engineers, PHYS-2050, for Spring. That was going to be my Sabbatical 1.22. But in fact I did end up with a Fall PHYS-2050 section, so four months of writing didn't happen. (grin)

For the regular semester it's best, given the economics of my long commute, to teach two classes. I agreed to one for the Fall because (a) it kept some money coming in, (b) it gave me a class to teach (!) and a reason to come down to the office (!!) and (c) I was expecting to teach two courses in the Spring. Alas, when contract letters came for Spring, there was only one section. At least it was the 1pm and not the 9am, as I currently have. While a nine o'clock is much better than an unholy eight o'clock, especially in the wintertime, it still has me leaving the house just about the time that Mrs. Dr. Phil is getting up -- and we do like to see each other on a regular basis.

Tuesday my boss said some things were changing and was I up for adding back the 9am section as well. I said sure, though it would be nicer to get a 10 or 11am class. I figured it wouldn't hurt to mention that. Well, there's that adage about the squeaky wheel...

An Upper Division Class

So then it was mentioned that if I was interested I could take the 10am PHYS-4400 Electromagnetism class. Oh well now there's an interesting thought.

Pretty much since I began teaching, I've been doing the introductory Physics courses, including the "third semester of the first year" Modern Physics course, at both Hope College and WMU. Twice I've taught upper division classes -- half of a math physics course at GVSU and a special Solid State Physics course for two zoomer seniors at Hope, using Kittel as a textbook. That last was in 1997. So (a) it's been a while since I taught an upper division class, (b) yes I was interested and (c) it isn't the graduate level course out of Jackson. (evil grin) That last point would be lost on most of you, but suffice to say that while I could probably teach the lectures for a Jackson-based class, there is no way I could do the exams, homework or grading. It's been too long, the materials are really tough and it's too short a notice.

But on Friday, I got an email from my boss wondering if I'd be in the office on Friday or Monday, as he had a revised contract letter for me, and I said I'm here now. And a few minutes later he came upstairs and dropped off the letter.

So... I DO get to teach two courses in the Spring and I DO get to teach a fun new course. (As opposed to teaching PHYS-2050 for the 21st time.) Ten registered so far, a typical load, about 1/3 of the names I recognize from first year courses without even doing a search of previous classlists -- all juniors and seniors. Already arranged to get a desk copy of the textbook shipped to the P.O. Box, rather than languishing in the university's mail room over break. (crafty grin)

All in all, a very pleasant way to end Fall semester's finals week. Now, back to grading papers...

That Smell? It's Finals Fear

It's Finals Week here at Western Michigan University. Finals are two hours long and close packed together with a whole fifteen minutes between sessions. The very first time slot was Monday 8-10am. And guess what? That was the scheduled time for my PHYS-2050 MTWRF 9am class.

Now this is good news, because statistically students do better when the Final falls in their normal class time, which this does. Bad news, because who the hell wants to have a Final at 8am in the bloody morning? For me, I had decided long ago that it would be easier if I would just drive down to K-zoo on Sunday afternoon and stay overnight in a motel, rather than trying to get up at 4am and then driving down in the dark. This plan looked to be real genius as the big Midwest winter storm rolled through.

Not The Walloping That Minneapolis or Syracuse Got

But during the weekend it rained. Sunday morning the roads were wet and the temp still just above freezing. By 2pm, the temps were 25°F and dropping, and it was starting to snow lightly -- and the winds were picking up. Overnight a couple of inches was forecast, along with gusting over 40mph and zero-ish wind chills. Temps were going to be in the teens, below the effective temperature for the road salt chemicals. Peachy. When I left, the roads were already shiny -- you could get up to speed, but stopping was clearly an adventure, as were poorly advised high speed turns onto the highway from the side streets that I kept seeing. The anti-lock brakes chattered every time I had to slow for a stop light. Gear it down, 4WD, no driving like an idiot -- and it worked pretty well.

The communities right along the lakeshore have been repeatedly clobbered by lake effect snows. But some ten miles inland in Allendale, mostly all we've gotten is to see this wall of snow clouds off to the west.

Made It, Now What?

Eventually made it to Kalamazoo, mostly 10-15 mph below the posted speed limits -- only saw one accident on the side of the road. Before I'd left home I'd printed out the Kalamazoo 10 movie schedule, as that multiplex is just across the road from the Super 8 I was going to stay at. I'd hoped that maybe RED was still playing, as Mrs. Dr. Phil had seen it with her mom a while ago and I hadn't. But no. However, I checked into my room at 4:15pm and had plenty of time to make a 4:45pm showing of Tangled, the new Disney Rapunzel movie -- very cute. Came out of the theatre and had to brush off about two inches of very, very fine diamond dust snow off one side of the vehicle.

I'd gone ahead and made a reservation -- it was $49.44 at the Super 8 Motel site with AAA... and $50 at Motels.com -- but there may have been only one other guest staying there, based on the cars parked. (grin) Super 8 isn't a posh chain, but it's adequate. The Panasonic TV had a Zenith remote, probably with the wrong code number, as the volume controls worked but not the change channel. The room had one of those window A.C. units with a space heater in it -- the TV needed the volume up to 13 when the fan was on, 4-6 when it was off. Luckily, I did have the remote volume control. (double-jeopardy-grin) Watched some football, saw the finale of The Amazing Race and a new Series III Inspector Lewis on PBS.

There were a couple of tables and chairs in the lobby for the advertised continental breakfast. If you liked dehydrated blueberries, you had your choice of blueberry bagels or blueberry muffins. They had one of those close-and-flip circular waffle makers, but no batter and no one around. The cereal choices looked to be no-name Fruity-Ohs and nondescript corn flakages. I had a bagel with Philadelphia cream cheese. The guy in the white pickup I thought was the other guest pulled up to the door, came in and piled four muffins in a foam cereal bowl, and left. It was something. If I was desperate for a "real" breakfast, I could've driven five buildings down to the 24-hour Steak-n-Shake, which would've done fine real pancakes, but I passed. Besides, I bring cookies to my exams -- and name brand cookies for Finals.

A Clear Windy Dawn

I was prepared to dig the Blazer out in the morning, but not a lot of snow actually fell overnight. And the winds pretty much kept the windows clear. I thought the window washer jets were frozen, but later found that I was just out of blue fluid. Overhead was sparkling clear. Despite the bitter cold, the actual main streets were clear and wet. Side streets were slippery. I'd worried about what time they'd open the buildings up. But I got in around 7:20am and found both the classroom and the offices buildings unlocked, so didn't have to play ID card roulette and find out if my ID card was or was not currently programmed to open the doors after hours. (As a part-timer, they are always deleting us after one semester, but sometimes after they've added us for the new semester.)

And my finals were copied and left in the lock-up as expected. And amazingly, 52 students were there at 8am, out of 56 who'd taken Exam 3. 1 showed up at 8:10, and I knew 1 student was stuck in the U.P. with a breakdown and no mechanics open on the weekend. Of course I told everyone the storm was coming and that they shouldn't go out of town for the weekend, but they never listen to Dr. Phil. That errant student is taking his final as I type -- he's got about 17 minutes to go.

By the time I was heading back to Allendale at 2:30pm, it was blue skies, bright sunshine and dry main roads. Still a ground hugging vision of snow clouds off at the Lake Michigan shore, but we weren't getting the snow on Monday.

Now it's all over except for the grading. (triple-word-score-grin)

Before You Can Even Start To Get Any Work Done

With only 41 students left in my summer session course, it looked pretty much like I might be able to finish up Grade-a-thon early on Monday, instead of the last minute before noon on Tuesday. I might've just had the grader send me the final exam and last two quiz grades, but I did have a student making up the Final at noon, and besides, it is so much easier to be able to look over the graded Finals and make sure everything's all right.

As a part-timer, I don't get a yearlong parking hang tag. Instead, every semester I have to go into the Parking Office and get a new sticker or card or tag -- they keep changing the procedures -- and register two of my three vehicles. I'm not sure I remember checking the summer tag, but typically the tags run out on the last day of finals/classes, which for Summer -II was Friday 20 August 2010. Okay, but as an instructor who has grades to do, why wouldn't this go until the Tuesday the grades are due? (grin) Now I wasn't actually expecting that they'd bother ticketing anyone during Break Week, but the real advantage to hitting the Parking Office on Monday was that there was no line. (happy grin)

Upon Arriving

Grader had put Q18/19 and the Final Exams in my mailbox at the office, so I now had that. Yay! Two more things to tick off the checklist. Quizzes -- done! Science Literacy Book Reports -- done! All exams -- done! (Save for the make-up Final) All exam and quizzes corrections -- done! Curve for the Final -- done! Time to implement the Bad Test Day Rule, the unwritten rule which adds points to the lowest of Exams 1-3 up to the average of the other two exams plus the final -- done!

All I Wanted Was Some Water

A pinched nerve or something has bugged me for a couple of days. I didn't fill a bottle of water or buy one on the way in, because I knew I had half a bottle of water left in the office. Don't you just hate it when you're sure you know something, only to find out it ain't necessarily so? (evil grin) Well, that bottle only had a swallow in it. But I didn't want to leave my office before my appointment person came, nor did I want to limp around unnecessarily if I had to. So I did something I thought was clever. When my make-up final person showed up, I gave them $1.25 and asked if they would be so kind as to go down to the Rood Hall lobby next door and get me a water. No problem. Except...

Student returns and says the vending machines now say water is $1.50 -- and they have no money. Well of course. They want to gouge the students more, so raise the rates as soon as break happens. Give student another quarter.

Student returns. The quarter slot is jammed full of quarters, which he found out by putting a quarter and having it get stuck and not dropping, nor will it give money back. But there is another vending machine in the lobby on the other side So I gave the student two dollar bills, hoping they'll scan as well as bypass the change slot.

Long delay. Student returns with bottle of water and a bunch of quarters. Seems the Coke guy was restocking the first machine and cleared the jam and gave him the right change and the bottle of water.

Interestingly, I was expecting the Coke machine to dispense Dasani, but instead I got a bottle of Smart Water. Actually GLACÉAU smart water, if you read the label. When I got home with the rest of the water, Mrs. Dr. Phil wanted to know why I bought "smart water", a marketing scam we both hate, and I said, truthfully, it was what the vending machine had.

Still, I would've been pretty mad to have not taken down enough money to hit more than one machine. Guess I was happy to have a younger man do the running on this one. But $1.50? (rolls eyes)

All Over Except For The Screaming

Student took Final Exam, I graded it, then cleaned up the last of the grading, adjusting a course curve so we get sufficient A's. Finally I could call up and log into GoWMU's faculty page and enter the grades. Yay! Grades done!

Of course there's done and there's done. When I got home, I took the grading spreadsheet, sorted the entries by the student's Personal ID number they assigned themselves, then converted a table to HTML pre-formatted text. Once I posted the grades online, I waited for the inevitable emails.

The hardest and worst part of my job is explaining to students, in detail, while their final course grade isn't as good as their last predicted grades. While many people did better on the Final Exam, some did worse. And I fear that some people give up towards the end and not turning in the last quizzes and tanking the Final Exam, somehow thinking that they've got their passing grade in the bag. Unfortunately, it doesn't work like that.

No, I don't do extra credit -- it's in the syllabus. Yes, I did apply the Bad Test Day rule, adding in the extra points to the total, not changing the exam scores. Several hopeful people thought they still had a chance, when in fact, they didn't. I hate it when people fail (most students have to get a C or better in their major, so DC, D and E don't work for them), especially when we've talked in my office about what they needed to do to get a C or a CB or whatever, and then they don't do it. Check the math if you like, but the spreadsheet doesn't lie -- it can add up rows quite well.

I tell people the first day I'd be happy to give everyone A's, if they deserved it. They get the points and even when the dean comes down hard on me and says What Gives, I'd be able to say "Look at these scores, look at these hard Dr. Phil problems -- and still they got all A's." Yeah, I'd love to be able to defend that to my bosses.

Alas, such is not to be.

Tuesday

I was driving around doing errands, and bypassed the intersection of Wilson & M-45 and took the back way, which eventually turns into Linden. At one point as the road finally straightens out, there is a very large tree which overhangs the road. Approaching it at 55 mph, I realized there was a very large bird sitting on the topmost branch, with a very distinctive white head. Yup - bald eagle looking around for its next meal. With traffic, it wasn't easy to pull of the road, turn around twice and hope to get a picture before the eagle flapped off, so I didn't.

Yes, there are bald eagles in Michigan, and not just the U.P. In fact:
Bald eagles can be found in every state except Hawaii. They are more prevalent in Florida, Wisconsin, Washington, Minnesota, Oregon, and Michigan; the largest concentration is in Alaska.

So we're in the Top 7 states for bald eagle sightings. (grin) Who knew? And what fun!

The Usual Apology

It's that time of the semester -- Grade-a-thon -- as we finish up the rushed 7½ weeks of the Summer-II Session here at Western Michigan University. My PHYS-2070 University Physics II class, Electricity & Magnetism, is now done. The Final Exam was Friday. We are so ahead of the usual curve here. Admittedly, I have just 41 students instead of twice that many, but except for one double-quiz and the Final which are being done by my grader, and the Science Literacy book reports which I am doing now, I've got all the other grades, re-grades, corrections and turned in late scatter-gather quizzes, graded and recorded in the spreadsheet. That has got to be a record for me. (grin)

I've even done 17 of 40 papers. Time for a nap, before my eyes close for me.

Driving Hazards

But that's not what this post is about. Instead, I think it was Tuesday's drive in, about 9:52am EDT, as I was heading south out of Grand Rapids on US-131, heading up the hill past the exit for 84th Street, I saw something slithering across both lanes of the highway. Minivan ahead of me half drove onto the paved right shoulder, but I was going to have to move over a bit further -- and of course I was on the brakes -- to avoid running over...?

A spinning ladder. A two-section aluminum extendable ladder, which had spun on the pavement and now came to rest across all of the left-hand southbound lane and most of the right-hand. Just about perfectly perpendicular to the flow of traffic. There was plenty of time, relatively speaking to dump a lot of my speed before hitting the rubble strips on the right shoulder. I had no intention of running over an aluminum ladder at 70 mph and I also didn't want to hit the shoulder, paved though it might be, at 70 mph given that it was likely to have stones and other trash.

So no problem. Hazard avoided. Though there was plenty of southbound traffic behind me, and ladders don't sprout legs and walk themselves out of the way, so I hoped that those behind me could see that two vehicles had just dove onto the shoulder to avoid something.

Ah, But The Idiots

Of course as I'm passing the ladder on the right at 40-50 mph, there's some import SUV crossover clattering over the ladder in the left hand lane at 70+ mph. Nailed it good, so it just made a lot of noise, but didn't spin out to whack me or anything. Near as I can tell, no attempt to slow down or move to the right or left. Hmm, pay attention to one's driving much? I don't know if the driver was actually on the phone or whether that's just wishful/evil thinking from several days out on my part. (grin)

In that driver's defense, though, I did notice that further up the hill on the left-hand shoulder was a blue pickup truck -- and it was starting to back up. One would suspect that he's the one who lost the ladder. And he is the one I wish to vent my ire on.

See -- I didn't see any sign on the ladder that it had a red flag tied to either end. Or at least not a big one or a very visible one, a very common complaint of mine. And this pickup truck had no ladder rack, just the usual 8-foot bed. And given that this ladder, unextended, was nearly two full lanes wide, that tells me that the damned thing was too long for that pickup truck bed, which means it was probably just tossed in the back and sticking out over the tailgate, unsecured. Which means this was an accident just waiting to happen. No doubt the guy was accelerating up the hill when friction failed to keep the ladder in the back -- who could ever conceive of such a thing happening? (ironic grin)

I've seen a lot of this lately. Various construction and service vehicles with open backs and gear just lying around. One of my favorites was a truck carrying concrete construction forms which had these racks holding these foot-long or so spikes -- looked like multiple rocket launchers on the back. One had a slight angle on it, but one was completely level. How would you like to be behind this guy when he guns it and those spikes slide out of their slots and into your lane? Look, I understand Physics, so I'm not asking that things be hermetically sealed at all times. But Michigan roads are not smooth surfaces, and bouncing can move things. And I don't want to have to dodge your tools and I don't have time to rebuild my vehicles. 'Kay?

Likewise, I don't drive behind trucks holding trash bins or asphalt -- seen too many stones, clumps of stuff and trash fly out behind these trucks.

I tell you, folks, it's a jungle out there. Doesn't anyone ever write tickets?

Ticking Off The End Of Semester Tasks

The Final Exam for PHYS-1060 was back on Tuesday. Tuesday afternoon, Wednesday and Friday, had people coming in to take late Finals and very late Exams 2 or 3. Amazing what studying for a final can do to give a good result in a regular exam. (grin) Maybe I should give the Final Exam first. (evil-grin)

Most of the quizzes processed. I still have a few I have to input into the spreadsheet.

That leaves the papers.

Of Course Now I'm Sick

Everybody else, it seems, came down with H1N1 or whatever during the semester and amazingly I did fine. And now that I've had both seasonal and H1N1 vaccines, now I come down with... well, something. Mainly it's a sore throat, sometimes a dry tickle that makes me cough. Some sinus clogginess, but I've been able to breathe and smell (and taste), so go figure. Haven't felt particularly fevery. Tired and achy from time to time. You know, like when you're sick.

The Final Grind

Friday I got the Finals back from the Scantron center, entered them, put in a curve and then did my "Bad Test Day Rule" magic for those who blew one of the hour exams, but pulled back up for the final.

So what I mainly have left to do is read the hundred and twenty odd science literacy book-or-movie reports. The class roster grading sheet I printed is some 2 pages plus. First objective met and the short page 3 is done. Need to put real damage in page 2 tonight and page 1 on Sunday. Grades are due on Tuesday at noon. Complicating things are that some company is coming in for a day or two. I've bought online tickets to the 3:30pm showing of Avatar in 3D IMAX on Monday for all of us. It should be spectacular, if nothing else. (grin)

Still, I'm pretty happy one to have the one class this semester. It makes all this endgame stuff so much easier.

All this means I'm likely to be scarce for the next couple of days in terms of new long posts.

Dr. Phil

An Ah-Ha Moment

Tuesday, 21 April 2009 15:38
dr_phil_physics: (upsidedown-winslet)
It's Quiet -- It's Too Quiet

Actually, it's about right. In the midpoint of the middle of my three Final Exams. Will be a lot more crowded in here tomorrow. A lot of the Noon section of PHYS-2070 has bailed on this exam time because of a transportation conflict between the main campus and the engineering campus -- no way can you get from one to the other in the allotted fifteen minutes between finals. I can't remember now, did Northwestern have an hour between final time slots and Michigan Tech half-an-hour? Either would be more civilized.

How To Use A Calculator

So far no calculators have clattered to the floor, which during an exam always prompts Dr. Phil to announce "gravity works". But, sitting here and taking a break from typing -- and switching from my office glasses to regular so I can see the students -- I noticed something.

My high school Advanced Chemistry class was the first class in the city of Greensboro NC that was allowed to have calculators. It took most of the year, but we nearly all bought the same model, a Texas Instruments SR-51A. I'd seen an HP-65 at UNC-G once, never dreaming that at Northwestern I'd own one -- once the price came crashing down in February 1977 when the HP-67 came out. (grin)

But nearly everyone I knew used a single index finger to push the calculator buttons.

These Kids These Days

About half of the engineers in this class seem to be holding the calculator upright, not flat on the desk, and working their thumbs. Dammit, Jim, they're texting, not calculating!

Huh. I suppose, now that they know how to do that...
