I'm a scientist and an educator. And occasionally, I want to say things that I shouldn't say in front of the students. So, here I am.

Motivation
I saw part of an interview with Pat Summitt where she mentioned that the current generation of student athletes seem to be less motivated than her previous players. And her players should be among the most motivated of any college student athlete anywhere. This ties in with a recent discussion amongst the faculty that most of the students who are performing below average are doing so because they simply aren't doing the work. Lab reports? Apparently optional. Regularly turning in homework, if at all? Just busywork. Turning in a paper worth ten percent of the grade? Nah.
Speaking of student athletes, my school's basketball team made it to the State Quarterfinals, their best season ever. Nine out of the thirteen players on the roster have taken astronomy with me.
I do not assign any work that isn't useful. Do I assign a lot of physics homework? Yeah, and if the students do it, they tend to do very well on exams. Do I make my astronomy and physics students write short papers? Yes, I do, because synthesizing and articulating scientific ideas are crucial instructional objectives. I even tell them why I give them the different assignments. I make each assignment worth a decent chunk of their grade in the course, so it is worth their time to do the assignments. Motivation has always come from within for me. I'm most competitive with myself. So I find myself wondering how to motivate students to do work they just don't want to do?

Teaching moments
A few weeks ago, I had to deal with something that had yet to confront me as a teacher - one of my students committed suicide. I was informed by the college administration, and the campus mental health director offered to come speak to my class. It is a lecture class, but I have my students do group work, so several of the students who had worked with this student were quite upset. It was a rough time, but I'm glad the counselor came and talked to the class. At least one student from that class has gone to seek mental health counseling since, so some good came from it.
I'd also like to say that I would never have suspected this student to have been in trouble from his demeanor in class. You know how after every Virginia Tech-type tragedy there is the outcry to somehow identify troubled students? If I had been asked to provide a watch list, he would never have been on it. He was outgoing, participated everyday, had made friends... the class was stunned to find out what had happened. His family and friends have my sympathies.
On a lighter note, I used Saturn's annoying tendency to gain more moons as a way to talk about how technology enables more discoveries, how the moon is small because otherwise we'd have seen it before, and how silly it is to memorize facts (how many moons Saturn has) as opposed to understanding processes (most moons are small, captured objects, etc...). Having such an example of a fact that changed since the last class seemed to have an impact.

Assessment
This article about student expectations in the NYT combined with my observations of students taking tests today spur me to mention the following:
- Students now expect tests to be open-book/open-note. They seem to think that's the default mode, so that on the day of the test they are surprised that they can't use their notes. When did the default mode change? Should I start calling my tests "closed notes" to prevent this?
- I always tell my students how many questions and what type of questions (multiple choice, problems, essay, etc...) will be on each test. I announce it the week before the test, immediately before handing out the test, and keep the format the same throughout the semester. That withstanding, students still fail to complete the last questions if they are printed on the back side of the last page. I find this odd. Not only have they not completed the stated number of questions, but why NOT flip the page when all of the other pages have been double-sided? Shouldn't they look on the back just to make sure? I now try to remember to announce that questions are printed on the back (when they are), but I forgot in one of my sections today and had to send about 30% of the students back to their desks to finish the test.
- Because of the aforementioned difficulties on the last pages of tests, I have the students turn in the tests face-down. In a couple of cases, when I pointed out that the page was blank, the students told me that they didn't answer the questions because they missed the appropriate days of class. In fact one student, in an almost accusatory tone, responded, "You know I wasn't in class that day." And that excuses the students from learning the material how? I even post my course notes on the website!
Sometimes I feel like I work harder on these tests than they do!

Just thinkin'
Two days a week, as I leave the room in which I teach astronomy, a group of students start trickling in for the next class. It's a math course, but when I asked the students what course it was, the various responses included "Math for Dummies", "Special Ed Math", and "At least it's better than being in Iraq." The students range in age from fresh out of high school to a woman who must at least be in her sixties. From the level of activity before their class starts, it is like taking a step back into high school, into one of the rowdy classrooms full of students who can't settle down after a sugar- and gossip-filled lunch break. Turns out the class has the following description:
Fundamentals of Mathematics serves as an introduction to fundamental concepts of arithmetic. This course covers the arithmetic operations of addition, subtraction, multiplication, division and exponentiation on whole numbers, fractions, decimals and percents; ratios and proportions, an introduction to the different systems of measurement, and applications of these topics. This course is intended for preparation for Prealgebra.
No college credit is given for this course. Nor for the course that is next in the sequence. These students are enrolled in the most remedial math course that is offered at the school. I can't stop thinking about how I would approach teaching this course. I can tell that they don't want to be there... either they hate math or can't do math or hate that they can't do math. I can see embarrassment on some faces. But all of them have some goal that brings them there, some certificate or degree program. Wouldn't it be more embarrassing to allow oneself to be impeded? Isn't it empowering to address one's deficiencies? Shouldn't the students be proud of themselves? How can a more positive attitude be instilled in the students ? It's giving me plenty to think about.

Nineteen years
Today marks the nineteenth anniversary of my first date with Greg. That means I've been with him for half of my life. Whoa! I'm grateful for the years of fun, friendship, and cuddling and am looking forward to more.

Beauty
There is such wondrous beauty in the universe, is there not? Galaxy NGC 4921 and seemingly countless members of the Coma Cluster of galaxies, from Hubble:

That's just how it is
I noted that the Super Bowl pre-game show started FIVE hours before the game itself. I decided to wait to turn on the TV til about an hour before the game, and what did I see? A live interview with President Obama as part of the pre-game show. This demonstrates the kind of audience that the game typically gets - huge! The commissioners of the other professional leagues must wonder how they can make their playoffs this exciting. Simple answer - fewer games! Nothing is better than a one and done playoff.
Who to pick for this game? My first Super Bowl memory is the Steelers vs the Cowboys in 1970s. I was for the Steelers then because, really, who likes the Cowboys? The Steelers' ownership spawned the Rooney Rule, an action that cannot be downplayed. Also, the Steelers' uniforms have always appealed to me. Normally they'd be my pick, but they're playing the Cardinals. The Cardinals used to play about a five minute walk from my grad student office. They've been terrible for years, but somehow they've ended up in the Super Bowl this year. I'm not a Kurt Warner fan, but Larry Fitzgerald's play has won me over. (Cute, too, gotta say.) Alright, I'm cheering for the Cardinals.

Review of Books - 2008
Due to sudoku and Battlestar Galactica obsessions, I only read thirty books in 2008. The quality of the books was good, I'm happy to report.
In terms of non-fiction, two books stand out:
- Omnivore's Dilemma - Michael Pollan - This book makes me want to grow all my food. Fascinating insight into the food industry and how much corn we eat with every bite.
- The Varieties of Scientific Experience - Carl Sagan - This is a collection of lectures that Sagan gave on natural theology, to understand god without invoking the miraculous. A wonderful book, reminding me of all the reasons why astronomers were snapping up these Sagan posters at AAS last week.
The generation of astronomers who belittled Sagan as a "popularizer" is being replaced by those of us astronomers who exist because of him. He is still so missed.
Two of my favorite books of the year are debut novels by good folks I'm happy to know:
- The Magic Thief - Sarah Prineas - Aimed at middle-grade readers, this story is engaging and fun. A warning, though - do not read while hungry, or you'll end up making the biscuit recipe in the back of the book, just like I did. Yum!
- Superpowers - David Schwartz - College kids develop superpowers and deal with the consequences. This book manages to be both fun and poignant.
I have a few more books to recommend:
- Life As We Knew It - Susan Beth Pfeffer - This book is aimed at a YA audience, and it's all about the end of the world. I appreciated that the author managed to pull off a satisfying ending, well within the scope of the protagonist.
- The Necessary Beggar and Shelter - Susan Palwick - These two unrelated books are engaging and possess deep emotional power. The first is more magical, the second is more science fictional... they've both helped Palwick become a must-read author for me. More books, please!
- The Astonishing Life of Octavian Nothing, Traitor to the Nation, Volume II: The Kingdom on the Waves - M.T. Anderson - The language of this book is so luxurious I just wanna roll around naked in it. Not an appropriate response to what is supposedly a YA book, I know, but the word-for-word prose is just stunning. Anderson has crafted an amazing look at the plight of slaves during the Revolutionary War, and there is as much, if not more, there for adults to read, just like all of Anderson's books.
Happy reading in 2009! (Doh, new BSG is on in two hours!)

Space Stuff
I very much enjoyed my time at the AAS meeting last week. I used up my social quota for the year, having conversations with: Judit, Benjamin, David, Victor, Carl, Greg, Ravi, Russell, Seth, Mike, Robert, Ryan, Eli, Steve, Sumner, Rogier, Hwi, Amber, Beatrice, Hu, Paul, Rolf, Matt, Melissa, Joe, Violet, Fred, Eric, Anthony, Jason, other Lisa, other Steve, Scott, Tyler, Kristin, Kaz, Nimish, other folks at the education workshop, among others. Besides hanging out with folks, other highlights included:
- An excellent teaching workshop
- A great talk on the intersection of astronomy with art, history, and literature
- An introduction to WorldWide Telescope, currently just a Windows app.
- A poster on eclipsing binaries that don't eclipse anymore, which makes me wonder how many other objects that we've cataloged as one type have changed over time.
- Concept phase posters for a proposed new telescope that, if it gets the go-ahead, could be as revelatory as Hubble
All in all, not a bad way to start the year!

Interaction
I spent the past two days in an intensive workshop about training teachers. It was a fascinating way to look at our own methods of instruction in our classes. I got a lot out of the experience and enjoyed collaborating with new folks. Now, though, the real conference begins. The Winter meeting of the American Astronomical Society kicked off tonight, and there is a lot on the schedule this week. Given that the meeting is in Long Beach, I'm not so much tempted to play hooky. ;)

RIP Senator Pell
Retired Senator Claiborne Pell died yesterday. I just wanted to pay my respects to this man, who helped me and so many others go to college. My students are usually surprised to hear that I worked my way through college, with help from scholarships, loans, and grants, such as Pell grants. I think students expect their professors to have had it easier than they do. Senator Pell made it easier for a lot of us.

International Year of Astronomy
The International Astronomical Union and UNESCO have designated 2009 to be the International Year of Astronomy. You can find out information about projects celebrating astronomy at the official IYA website: http://www.astronomy2009.org. For those of you who enjoy podcasts, check out the 365 Days of Astronomy podcast, which you can subscribe to via iTunes or RSS feed. If you're feeling social, here are the Facebook group and Twitter feed.
Although every year is a Year of Astronomy for me, I'm trying to think of an event or two that I might get approved for my campus. But most importantly for all of you, take some time in 2009 to look up at the sky and appreciate the universe.
