The Experimental Classroom

I just got home from the Joint Statistical Meetings (JSM).  As always, I found myself sitting in on different sessions and getting some very good ideas for activities I might try in my own courses, or new ways of teaching that I might want to employ.   I realize, however, that so often, I go to conferences and feel immediately energized and excited about new ideas, but when I get home and teach again, I end up falling back on what I always do or what seems most comfortable for me to do.  Why is that?

I was thinking about this a lot at JSM, and I think part of the reason I don’t revolutionize what I am doing is because I am uncertain about what the outcome might be (even if I hear that others have observed positive outcomes), and I want to “do no harm” to my students.  I’m not at all hesitant when it comes to “experimenting” here and there with a new activity or a new way of explaining a concept, but making sweeping changes in my entire curriculum is a whole different can of worms.  How can I change my attitude so that I no longer feel this way?  I think there are so many things I could do to make my classes better and to give my students a more meaningful learning experience, and even if it takes me outside my comfort zone, I know I owe it to them to give it a try.

As I was walking from one part of the Miami Convention Center (Hall A) all the way over to the other side (Hall D), I found myself dreaming about how neat it would be if we could each have an “experimental classroom.”  What if we had a class full of students who were there just to be “guinea pigs” for us as we tried new things solely for the purpose of seeing how those things would work?  These students would be there to learn and give us feedback, and we would assess them, but their grades wouldn’t really count toward anything.  We’d have the opportunity to try things out and observe how they work, and perhaps even have miniature focus groups throughout the semester to learn more from the students about what they liked and did not like.  We could bring in different textbooks and try them out one at a time to see which one worked the best (or to see if a textbook is even necessary), and we could do something similar with software programs.   We might adopt radically new ways of teaching that involve presenting topics in an unusual order, omitting certain topics altogether, adding more advanced topics, or moving from the traditional approaches to randomization-based approaches.   We could do all sorts of really neat stuff without worrying that our students would not “get it,” or that they would fail because of mistakes WE as teachers might make.  We’d have that freedom to truly experiment just to see what might happen.

I get a very happy feeling just thinking about how cool that would be.   :-)

Self doubt

Living far from campus means I have quite a bit of time to think about things when I’m driving to and from work.  On the days when I’m teaching, I often go over what I plan to do in class when I’m driving to campus, and then I go over how I think things went when I’m driving home.

Almost every day this summer, I’ve left campus wishing that things had gone differently in my intermediate statistics course.  I don’t know why, but I often don’t feel I’m doing what I should be doing in that course.  I’ve struggled a lot to find the perfect book (and I’m still searching), and I often think that the activities I use could be improved upon and changed.  I think about different data sets I could be sharing with the class, or data we could be gathering and exploring as a class.  I think about the many activities I use in the introductory course that involve food of some kind (often a hit with the students) and the lack of such activities I have in the intermediate course.  I constantly question the amount of detail we should be going into on different topics, and I wonder if the order of topics is appropriate.  I wonder if there are certain topics (like analysis of covariance and repeated measures ANOVA) that I should omit from the course, and I wonder if there are other topics (like maybe logistic regression) that should be included.  I wonder if SPSS is still the best software to use in the course or if I should begin transitioning to something else, like R.

I find myself feeling filled with a lot of doubt where this course is concerned, and I never know if that is a good thing or a bad thing.  In a way, I suppose it’s good, because my doubts often motivate me to make improvements and “do better” the next time I teach the course.  I never settle for the status quo, and I’m always on the look out for new activity ideas and new ways of explaining things.  I’ve even started bringing in journal articles to the course for students to read and discuss, and I like to think that has added an important element to the course.  I want students to have opportunities to see how the techniques they are learning about are used in real studies and how the authors of these studies present their findings.  I also want my students to have opportunities to question the findings reported in these articles and to apply some of what they are learning in class as they attempt to make sense of the findings.

Although I continue to have my doubts, I noticed something very interesting yesterday when I was driving home:  I actually felt content for the first time in weeks.  I didn’t question what had gone on in class because I felt that overall, things went pretty well.  Prior to that class, I found myself trying to share too much with the students about multiple regression and trying to delve into things that were more advanced and that really went beyond the scope of the class.  There was so much I was excited to share with them and that I wanted them to know and understand, but it was clear that they were getting bombarded with too much information, too quickly.  I knew my students were feeling confused and uncertain, and my resolve, on Monday, was to try to backtrack and ensure they understood the “big ideas.”  We went through a couple of activities together and also talked about a journal article where multiple regression was used.  I felt good about how things went, and I got a lot of good ideas for how I might better structure that unit in the course the next time I teach it.

Of course, I’m very biased here.  Even though I felt class went well, it’s not always easy for me to “read” my students, and I’m not sure if they share my enthusiasm.  I’m hoping they too were feeling good after class, but I suppose only time will tell if the pieces are starting to fall into place for them.

My love/hate relationship with my new phone

I got a smartphone in May and I absolutely love it.  I also sometimes hate it, but I definitely love it more than I hate it.

http://theoatmeal.com/comics/smartphone

I put off getting a phone like this for quite a long time.  I was perfectly content with the little Tracfone I carried with me in case of emergency.  I was convinced that if I had anything more sophisticated than that, it would just end up being a distraction.  More and more, however, I began to notice that so many of the people around me had smartphones, and I started to think having one might come in handy, especially given the work I do and the interests I have in technology.  I convinced myself that because I needed to be up-to-speed on the latest gadgets, getting a smartphone would be a very good investment.  I also convinced myself that having a smartphone would allow me to be more efficient.  Rather than waste time standing in line at Starbucks (for example), I could be standing in line AND catching up on my e-mail.  That seemed like such a win-win situation to me.

So, in May, Chad and I drove to our local Radio Shack and got a couple of Verizon smartphones.  It didn’t take us long to master the art of using them, and we soon discovered an exciting array of apps that would do things like give us directions when driving, find restaurants for us, allow us to listen to music or play Othello, and even connect our computers to the Internet for us.  It was a whole new world for us.

I do love all that my phone can do for me, and I must say that I HAVE felt more efficient lately because of it.  One of my biggest pet peeves is wasting time, and I like that if there is someplace where I have to be waiting or if I have nothing else to do, I can pull out my phone and check my e-mail, or read the news of the day, or even play a game.  I love that when I’m going on a bike ride now, I can pull up my Pandora app and listen to music through my phone (and even take pictures of neat things I see along the way).  I also like that Chad and I keep in touch and text each other during the day.

What I hate is that sometimes, I think my phone makes me MORE reliant on technology than I’d like to be.  So much of my work relies on using technology, and I feel that I need to break away from that now and again.  I worry that my phone is sometimes too much of a distraction, and that it’s making me more “connected” than I should be, or than is healthy to be.

Still…I do love this phone, and, right now, the pros far outweigh the cons.  Hopefully that is how things will remain.  :)

Keeping up with it all

I normally teach in the classroom during summer session, but this summer, for a variety of reasons, I decided to try to teach a fully online section of our introductory statistics course.  I’ve taught this online course for years during the regular 16-week semester, so I’m well aware of the workload.  Even during a regular semester, it can be challenging to keep up with everything, and it seems like the online course tends to be more work for students than the face-to-face counterpart simply because of increased reading and writing demands.  I worried a lot about trying to cover so much material–online–during our shorter 8-week summer session, but I knew the time had come to offer an online option for our summer students.  I thought this might end up being more flexible for students, especially since many of the students who tend to take this course live far from the Twin Cities.  It also seemed like the online course would better work with my own summer schedule and the plans I had for travel.

To make the workload manageable in the summer course (for the students and for myself), I ended up making a few changes.  Small group discussion is still a big component of the course, but students now work through six rather than eight group discussion assignments.  Students also have a project they must complete that involves gathering data, exploring that data, and analyzing the data.  That assignment has usually been an individual assignment, but this summer, I decided to give students the option of working on the project in pairs or small groups of three.  Interestingly, most students decided to work on their own, but I do have a handful of small groups, and I’m hoping this will make it easier to grade the projects and get timely feedback to students (especially since I have 40 students and the projects will come trickling in when I am away at a conference).

So far, I feel it’s worked well to have the course online during a summer session, and I’ve definitely learned a lot that I know will help me better structure the online version of the course should we offer it again next summer.  My students are all working hard, and I’m so proud of them.  I appreciate that it’s been challenging for several of them to digest so much material in such a short amount of time, but they continue to amaze me each day with their high levels of participation and the questions they are asking.  We are now just about to end Week 5, and it’s hard to believe we’ll be done soon, especially since there is so much more we still have to cover.

I think the biggest challenge for me has been keeping up with the volume of discussion.  I worried about this, and even though I feel I have a lot of experience now under my belt in terms of handling online discussions, part of me still feels like I could be doing so much better, and that there is an easier way to keep up with it all.  Near the top of this post, I’ve shared a screen shot of the number of posts (2,379) that have already transpired in the course.  This is more than I typically get during a regular semester, and we still have two more discussion assignments on the horizon!  Of course, I don’t generally have this many students, and the students have more time during the regular semester to digest material and reflect on that material (and thus might not have as many questions/concerns as a result).  I love the fact that through discussion, I can interact with each and every student, and I never want to lose that in my online courses.  I just worry a lot about being efficient, and about putting too much pressure on myself to be an online presence for students.  My own posts (404) now constitute a little over 16% of all discussion posts in the course.  Am I being TOO active?  Maybe, but it’s hard for me to imagine running the class any other way.

Standing up straight

 

If I had a nickel for the number of times my father told me to “stand up straight” and “quit slouching,” I’d be a rich woman now.  Now that I’m older, I wish I had listened more because I don’t feel I have the best posture, and I worry it will just get worse as the years go by.

Because of those fond recollections I have of my father’s admonitions, I think I was drawn to this media report about how good posture supposedly makes you “tougher.”

http://www.sciencedaily.com/releases/2011/07/110712133337.htm

Since the actual study looked interesting to me, I tracked it down, and I think this will make an excellent article to share with my students for one very important reason:  the authors use regression to analyze their data and talk about using “dummy variables” to represent different yoga poses that participants were asked to assume in the study.  I spend a little time in my intermediate statistics course talking with students about how ANOVA and regression are related, and how we could use dummy coding to turn a problem that would normally be analyzed via ANOVA into a regression problem.  This might be a good article to ask students to read and critique.  If anything, I’m hoping it might serve as a nice illustration for how students could write-up the results of an analysis where they used dummy coding.

The Lonely Bathing Beauty

I am a bath person.  I will take a shower when I have to, but I much prefer soaking in a hot tub at the end of a long day.  There is just something very soothing and relaxing about that.

Today, I learned that there is a reported relationship between loneliness and bathing.  According to a new study which is described in the following media piece, “…people who take frequent long, warm showers or baths tend to be lonelier than folks who spend less time bathing and like cooler water.  Researchers suspect that the physical warmth of a shower or bath provides people with a substitute for a lack of social warmth, or coldness, in their lives.”

http://bodyodd.msnbc.msn.com/_news/2011/07/01/6992690-wash-the-loneliness-away-with-a-long-hot-bath

I’ve already tracked down the original study, and it seems like there is a lot I could ask my students to talk about, such as issues related to the size of the samples used and the composition of the samples, the way variables were measured, the way the data was gathered and analyzed, etc..  In particular, I like the following sentence from the media report:

“The degree to which students felt lonely accounted for nearly 25 percent of the variation in their bathing frequency.”

Would students know this is a reference to r-squared?

Garage sale therapy

Chad has always enjoyed going to garage sales, but it took awhile before I could share in his enthusiasm.  I’m not sure where my initial aversion to garage sales came from, but there was just something I found very unappealing about going through other peoples’ personal belongings, even when it was clear that these people wanted to get rid of those belongings.  I also worried a lot about picking up more “junk” when I have plenty of my own at home.

I’m not sure what changed, but I slowly began to warm up to the idea of going to garage sales, and now, I look forward to those times when Chad and I can steal away and spend a day just driving from one sale to another.  This often ends up being our “date” time, and we enjoy driving to new destinations each time and meeting interesting people.  We also love the treasure hunting aspect of going to garage sales.  From one sale to the next, you never know what you will find, and that is very exciting to us.

Today was an especially great day because we found two bikes in very good condition, for an amazing price.  I’ve wanted a bike for so long now, and I finally have something I can easily ride through our neighborhood.  I’m so happy about this!  We weren’t really looking for bikes today or even thinking about bikes, but we couldn’t pass up this deal.

Of course, as soon as I got home, I had to ride the bike and try it out, and, as I typically do, I completely overdid it.  I rode for at least five miles, and although that probably doesn’t seem like much, it was a lot to me.  I’m not in the best shape now and I honestly thought I’d have to turn around after just a couple of blocks, but I wanted to prove to myself that I could do it, so I kept going.  I need to get into better shape, and I’m hoping this will be the start of that.  I’m also hoping Chad and I can find some cool places to ride together.

My goal now is to try to ride every day if I can (provided the weather allows for this).  There is something I love about being able to get from point A to point B so much quicker than I could if I were walking, and I love the feeling of the wind in my hair and the sun on my face as I’m pedaling along.  I also think riding my bike will be a good escape for me.  There is only so much I can take of sitting in front of a computer and working day after day.  We live in the country and there are always neat things to see, and I’m hoping I can try to document that.  Today, I saw a large turtle crossing the road (see the picture above), and I also took a couple of pictures of my ride down County Road 3 (we live right off of County Road 3) and a hay field.

All in all, it was a great day, except for that part when I was riding my new bike and these two dogs started chasing me down the road.  That was kind of scary.

Making accommodations

I sometimes wonder just how many online instructors think carefully–when designing their online courses–about how students with disabilities might interact with their course sites and their online materials.   When I first started to teach online, I’m ashamed to say this was not something I put a lot of thought into, primarily because working in the online environment was so very new to me, and there were so many other challenges competing for my attention.  Even in a face-to-face classroom setting, I worry that I don’t give this the attention it deserves until I’m actually faced with a situation in which a student with a disability registers for my course.  I feel I need to change my way of thinking about this, especially in light of this recent article in The Chronicle of Higher Education.

http://chronicle.com/blogs/wiredcampus/blind-florida-state-u-students-sue-over-e-learning-systems/32028?sid=wc&utm_source=wc&utm_medium=en

When I went through training this last fall to become a Quality Matters peer reviewer, I learned more about the kinds of accommodations that online instructors can make for students with disabilities, and this was very helpful in terms of thinking about how I might better structure my own courses.  One part of the Quality Matters rubric deals with the accessibility of the course site and the materials on the course site, and I can’t help but wonder how my own courses might be rated on this portion of rubric.  One thing I realized when I went through this training is that most times, when I thought about the design of my course materials and how accessible they would be, my focus tended to be on students who might be deaf or who might have other hearing disabilities, probably because I’ve had several deaf or hard of hearing students in my courses over the years.  I think this is partly why I’ve steered away from using a lot of video in my online courses.  I just assumed that information in text would be more accommodating and accessible to most students.

It wasn’t until this spring, when some colleagues and I met with Philip Kragnes, an Adaptive Technology Specialist who works with the Computer Accommodations Program at the University of Minnesota, that I started thinking carefully about how I needed to make sure my courses were also accessible to blind students.  Philip is blind, and it was fascinating to talk to him and to see how his screen reader was able to read information for him.  It was also very interesting to hear more about how we–as instructors–can think about the ways we are designing our course sites.  Sometimes, little things that we think might “jazz up” our sites (such as adding different kinds of headings, etc.) will only lead to problems for screen readers.  This never even crossed my mind.

Once again, I find that I still have A LOT to learn.

Walking to school

I went to two different elementary schools, and we lived within about six blocks of each of these schools.  I liked being able to walk to school, and I was able to continue walking to school up through junior high (since the only junior high school that was in our town at that time was just around the corner from my house).  The high school was all the way on the other side of town, so I had to take the bus during my high school years, until I had a driver’s license and could drive myself to school.

A new study has been published about some of the health benefits of walking to school.  According to a report of the study that is now on the CNN website:

“Children living in urban areas and from lower-income families are more likely to walk or ride a bicycle to school, according to a study published in the journal Pediatrics on Monday.  Those activities have proven health benefits. The study involved more than 7,000 children aged 6 to 16 living in Canada who were followed throughout their school years.  Among the findings: Children aged 6 to 10 were more likely to choose active transportation – walking or cycling over inactive transportation, like riding in a school bus, a car or taking public transportation.”

http://thechart.blogs.cnn.com/2011/07/04/whos-walking-to-school/?hpt=he_c2

I wonder how this might compare to children living in the United States.  I also wonder if there was an attempt to see if the students who walked or rode bikes to school were indeed “healthier” than students who had no other options but to take the bus or be driven to school.

Getting back into the swing of things

When my husband first encouraged me to start a blog, I worried a lot about starting something that I couldn’t finish or that I couldn’t keep up with. I didn’t want to start a blog only to have it sit for weeks at a time without any new posts. In my mind, if I was going to start a blog, I was going to thrust myself into it and keep it fresh. I couldn’t imagine doing it any other way.

Now, of course, I have come to that point where I’m not updating things on a regular basis, and this has been troubling me. I have no excuses other than the typical “life got in the way.” As I’ve reflected on time and again on my blog, I bit off more than I could chew over the last academic year, and in some ways, I sort of crashed when the year ended. Not that this was such a bad thing, mind you. I knew going into the year that I had a tough road ahead, but I don’t think I realized how much I would learn about myself in the process, and for that, I’m very thankful. I feel I gained a new identity this past year, and I figured out just what I want to do and just what I should be pursuing (and what I should say “no” to). One of my biggest triumphs was re-discovering how much I love to write. I co-authored one article that has been submitted for publication and I’m close to finishing another one, and I was also asked to write a regular column in eLearn magazine. Of course, on top of that, I’ve been able to share thoughts and ideas within this blog, and I’ve actually enjoyed that so much more than I thought I would. In a way, it’s been very good therapy for me.

So, with that said, my goal now is to keep this blog from getting “stale.” I tell my students all the time that we are bombarded by statistics every day and there is always something being shared in the media that we can critique and relate back to the introductory statistics course. I want to share more of things I am finding that excite me and get me thinking about teaching issues and activity ideas. I actually have a list of such things that I’ve wanted to write about but just haven’t had the time to write about recently. I think it’s high time that I start making that time again! Beginning tomorrow, my goal is going to be to update my blog daily.  I guess we’ll see how that goes.  :)
