Rock Paper Scissors

My husband and I often play Rock Paper Scissors in order to determine who will take the dogs out, or who will let the chickens out in the morning, or who will have to do a dreaded chore of some kind around the house.  I’m not sure how it all started, but it seems like we play that game at least every other day.  I remember hearing a radio report–awhile back–about a study related to Rock Paper Scissors, and it was reported that Rock was the most popular among the three possible moves in the game.  Thus, you might begin the game with Paper if you think your opponent will choose Rock.  However, your opponent might think you are going to choose Rock and begin with Paper, so you are really better off, because of that, choosing Scissors.

Hearing about that study got me thinking about whether I might be able to design some kind of classroom activity around Rock Paper Scissors.  I’m not sure what it would look like or where exactly it would fit into the curriculum, but it makes me smile to think of a classroom full of students playing Rock Paper Scissors.

Did you know there is a society–the World RPS Society–devoted to Rock Paper Scissors?  They even have national championships!  They share many interesting strategies on their website about how to beat others at Rock Paper Scissors.

http://www.worldrps.com/how-to-beat-anyone-at-rock-paper-scissors

I especially like the following information that is shared on the site:

“Contrary to what you might think RPS is not simply a game of luck or chance. While it is true that from a mathematical perspective the ‘optimum’ strategy is to play randomly, it still is not a winning strategy for two reasons. First, ‘optimum’ in this case means you should win, lose and draw an equal number of times (hardly a winning strategy over the long term). Second, Humans, try as they might, are terrible at trying to be random, in fact often humans in trying to approximate randomness become quite predictable. So knowing that there is always something motivating your opponent’s actions, there are a couple of tricks and techniques that you can use to tip the balance in your favour.”

The site goes on to add that males have a tendency to lead with Rock on their opening throw.  Of course, I knew that.  How do you think I’m able to beat Chad so often?

Is this the next great student excuse for skipping class?

I really hope I don’t start hearing this in the future:  “Dr. Everson, I thought it would be okay to miss your class because the Skip Class Calculator told me it would be.”

New Beginnings

Part of my reason for starting this blog is that I wanted a place where I could reflect on my teaching.  I feel that I’m embarking on many new projects this fall and I have many great new opportunities, and I want to learn and grow as much as I can.  Fall semester will begin next Tuesday, and I realized today that fall is going to be a new beginning for me, for many reasons.  It has to be, because I’m not entirely happy with how things are going in my life right now and I feel it is important to make some changes.

This morning, I took a walk across the bridge behind my building.  The bridge crosses the Mississippi River, and I didn’t realize until earlier this week that if I walk across the bridge I can easily get to the West Bank of the U of M campus.  My plan is to cross that bridge as often as I can this fall.  I definitely need the exercise, but more importantly, I need a break from technology.  I need to get out from behind my computer and smell the fresh air.  I need to live a little bit more than I have been lately.  I love what I do, but I find that I’m just not as active as I used to be, and I’ve gotten so engrossed in my work that I’ve lost sight of things that used to make me really happy.   I’ve put off doing many of the things I really want to do because I feel I need to be working all the time.  Why do I feel that way?  Walking across that bridge today made me remember how much I like to be out walking.  Walking allows me to think a lot and reflect on what I’m doing and what I’d like to be doing.  Many times, the thoughts I’ve had while walking have led to the start of new papers, or to the writing of new class activities.  Today, I remembered all the times I used to walk over to the West Bank as a grad student to hunt for various books and articles in the library.   I’ve gotten so lazy where that is concerned.  Now, if I need an article, I can usually just go to the library website and download a PDF copy.  I can’t even remember the last time I walked over to the library!  This fall, I’m going to begin to walk again, and I’m hoping that by becoming more active, I’ll regain that energy and enthusiasm that I feel has been dwindling lately.

I’m also hoping the fall will be a time for me to get a better handle on stress management.  Today was rough because I thought–for a good chunk of the day–that I had lost a flash drive that held many important notes and handouts for one of my classes (not to mention all my conference presentations and papers I had written).  The day got off to such a good start with my morning walk, but as soon as I got back to my office, panic set in as I discovered the flash drive I thought was sitting on my desk was not there (and I knew it was not at home since I had been looking for it there since Monday).  All I could think about was how much work would be involved in trying to re-create class materials that had taken years to compile.  I was so upset, and I almost skipped an important meeting because I felt like I couldn’t  concentrate on anything when such a huge chunk of my work was possibly lost forever.  In the end, I didn’t end up skipping the meeting, and shortly after it got started, I suddenly felt a feeling of calm come over me.  I realized that maybe I had lost that flash drive for a reason.  Perhaps it was a sign of some kind that I needed to quit relying so much on what I’ve done for years and instead start fresh with new material.  Or, maybe it was a sign that I needed to be much better about backing up my important files.  It dawned on me that I was getting way too worked up about something that I couldn’t change, and I can’t continue letting stress consume me like that. 

I eventually did find my flash drive.  It must have fallen out of my bag in my car and slid under the front seat.  I can’t even describe the feeling of relief I had when I found it this afternoon.  I like that I’m not going to have to rebuild everything and start from scratch.  However, I now know I could do that if I had to, and it would be okay. 

This fall is going to be busy, and tough, and it will test me in so many ways, but I’m ready for that.  I’m looking forward to a new semester, and lots of new beginnings.

Research suggests being a “mama’s boy” is good for your health

When I saw the headline for this article, I thought it would be an interesting read, just because I’m curious about what constitutes being a “mama’s boy.”  I’m not sure the article really answered this question for me.  Is it just being close to your mother?  Is it “shunning masculine stereotypes and remaining more emotionally available“?

http://www.time.com/time/health/article/0,8599,2014038,00.html

Maybe I should bring this to class and ask my students what they think.

A moment of clarity

Slowly, as I get ready for another semester, the pieces seem to be falling into place.  I was involved in two different workshops in August–one through my college and one at the university level–and both workshops introduced me to great new technologies and gave me lots of new ideas for activities and assignments I might try out in my courses.  There is so much we CAN do with technology, and there is so much I want to experiment with, but, at the same time, I don’t want to overwhelm my students!  Because of this, I’ve been thinking a lot over the past several days about ways I might be able to incorporate new tools into my courses without making my students feel uncertain or uncomfortable.  I think I’ve come up with a solution.

I keep coming back to the idea of giving students more choices in terms of the assignments they complete and how they complete these assignments.  I strongly feel that if an instructor wants to use social media in the classroom, students need to have some say in the matter because not all students feel comfortable using social media or want to use it for educational purposes.  I decided, therefore, that I needed to create an assignment that students could approach in different ways.  This way, students can choose an option for completing the assignment that appeals to them the most or that they feel most comfortable with.  Traditionally, I’ve asked students in one of my courses to find and critique a journal article (ideally from an area that is of interest to them), and this is a great way for me to assess whether students are understanding some of the terms, concepts, and ideas they have learned in the course (and whether they can apply what they have learned).  I started thinking about this assignment and I wondered if there were other ways students could show me what they have learned in the course and how they might apply it.  What if–for example–I asked them to use Twitter or Facebook to share and reflect on news stories or resources they were finding that relate to the content of the course?  Or, what if I asked them to create a YouTube video in order to try to teach others about something they learned in the course?  What would happen if I allowed students to choose what they wanted to do in order to complete this assignment?  Would more students choose to complete an article critique and not bother at all with social media, or would more students gravitate toward using social media?  Would I see similar patterns–in terms of how students choose to complete this assignment–in my online and face-to-face sections?

I guess I will soon find out because I’m definitely going to try out this new assignment in the fall.  I can’t wait to see what happens!

Studies Reveal Significant Weight Loss Without Changes to Diet or Lifestyle

Wow!  I can lose weight without changing my normal eating or exercise habits.  All I need to do is sprinkle some Sensa crystals on my food.  STUDIES have actually been conducted and have shown an average weight loss of 30 pounds if you follow the Sensa diet.  This is amazing!!!  I’d really like to see these studies.  Where can I find them?  These are LANDMARK studies, according to the site I’ve linked to below.  Too bad the site doesn’t provide any references so I can track down this research. 

http://amazinglivingtools.com/WeightLoss/index.htm

This reminds me of a story I saw awhile back on “20/20″ about Dr. Alan Hirsch and his Sensa crystals.  I was skeptical then and I still am.  Anytime someone tells me I can lose weight without exercising, I’m skeptical.

Assigning Students to Small Groups

If you use group activities inside or outside of your classroom, you might learn a few things from this article.  The author explains how she goes about assigning students to groups to work through discussion assignments and other activities in her classroom, and she invites others to share their ways of assigning students to groups.  The comments to this article include lots of interesting ideas, and also bring up some good questions.  For example, should students be randomly assigned to groups without taking into account their backgrounds and ability levels?  Is it better to have students work with ONE group throughout the semester or quarter, or should groups change a few times so students have opportunities to work with and get to know more of their peers.  What do you think?

http://chronicle.com/blogPost/Assigning-Students-to-Small/26557/?sid=wc&utm_source=wc&utm_medium=en

I must admit that in my face-to-face courses (where I teach graduate students), I do use lots of group activities, but I’m not very good when it comes to assigning groups.  Most often, I let students work with the other students who are sitting near them and I haven’t encountered too many problems doing this.  Maybe this is why I haven’t tried anything else!   Every now and then, I might have an activity where I want to “mix things up” a bit, and in that case, I usually number students off as a way of grouping them (e.g., all the “1′s” get together in one area of the room, all the “2′s” in another area, etc.).  It’s not a terribly creative way to group students, I know, but it gets the job done quickly.   In my online courses, students work on small-group discussion assignments and I generally change the groups one time–around the middle of the semester–so students can complete four assignments with one group and then four with another group.  When I initially group the students, I usually try to mix them up in such a way that students in one group are not all from the same field of study, but I’ve done many different things in my online courses when it comes to creating discussion groups (e.g., sometimes I just randomly assign students to groups, other times I use a more systematic method and put every fifth student on my class list in one group, etc.). When I re-assign students to groups, my goal is to provide students with opportunities to work with a new group of peers.  I also use what I observed about student contributions to earlier discussion assignments to guide my decisions, to a certain extent.  For example, I would not put all of the students who were the least talkative or who participated the least in one group together. 

The author of this article mentions that she changes groups about three times during the semester and she describes a system she uses to make this manageable.  I remember at one time I was on the hunt for very creative ways to group students to work through activities, and I stumbled upon one example in the instructor’s manual for an Educational Psychology textbook.  This idea involved finding several comic strips that each contained a certain number of segments (e.g., perhaps four or five segments depending on how large you wanted your groups to be).  Because I teach in an Educational Psychology department, I tried to compile comic strips that related in some way to education (or statistics).  Once you had the strips, you needed to cut them up so that each segment was by itself.  You would then mix all the segments up, hand one segment to each student, and then ask the students to walk around the room and find the other students who had segments from the same comic strip.  Once all the students were together in a group, their first task was to put the segments in proper order to form the comic strip (and maybe even spend a little time talking what is funny about the comic strip).  I might have to try this again since just writing about it here reminds me of how fun that was!

Today’s college students?

Awhile ago, I learned about a video called “A Vision of College Students Today,” and one of the first thoughts I had after viewing this video was “how can I integrate this into my classroom?”  I wondered if my own students could relate to anything presented in this video, and I was curious about what their initial reactions would be after viewing it.  I imagined lots of great discussions we could have about how the data presented in the video was gathered.  Who was in the sample and how was the sample obtained?  Is the sample representative of college students?  What kinds of questions were included on the survey and how were they worded?  From the video, it appears there were 200 students in this sample, and they “surveyed themselves” by collaborating on a Google document.   Could this have biased the results in any way? 

As I thought more about how I might turn this into an assignment, I found myself wanting to learn more about this video and just why it was created.  I wondered if I could find any other documentation about the video, and after doing a quick Google search, I discovered a website that shared more of the story behind the video. 

http://www.britannica.com/blogs/2008/10/a-vision-of-students-today-what-teachers-must-do/

I learned the video was created by Michael Wesch, and I wrote to him to see if I could find out more.  He then shared a journal article with me that he wrote about the video.  The video and the article paint a rather dismal portrait of today’s college student.  When I finally did write an assignment based on this video, I asked my students to first watch the video and then read Wesch’s article.  I asked them to talk about issues related to sampling and survey construction, and I also asked them to think about the many claims Wesch makes about college students today and to discuss ways they might be able to test those claims.  Wesch claims, for instance, that there are problems with education and students today are disengaged.  He claims that while many of us love learning, we hate school, and students struggle to find meaning and significance in the classroom.  He claims that students tune out what is going on in the classroom and instead log on to Facebook.

As I revisit the idea of trying out this assignment again this fall, I find myself once again watching Wesch’s video and feeling very sad.  This was not the experience I had as a college student, and I hate to think that what I am seeing in this video is now the rule and not the exception.  How can we change this?  Perhaps we as teachers need to re-think what WE are doing to engage our students and make the learning experience meaningful for them.  Faculty at the University of South Carolina have some good ideas, as you can see below in their video response to “A Vision of College Students Today.”

Why do heavy drinkers outlive nondrinkers?

I just read an article in Time magazine.   It describes a recently published paper about a study that was conducted in order to examine the relationship between alcohol consumption and mortality rates.  I originally thought it might be something to share with my students.  I like that it includes information about the sample and that it discusses variables that were controlled for in the study.  However, I wonder if this article might send mixed messages to readers–especially those who may not realize that correlation does not imply causation.  I say this primarily because of the last two paragraphs in the article.  The second to last paragraph states the following:  “The authors of the new paper are careful to note that even if drinking is associated with longer life, it can be dangerous: it can impair your memory severely and it can lead to nonlethal falls and other mishaps (like, say, cheating on your spouse in a drunken haze) that can screw up your life. There’s also the dependency issue: if you become addicted to alcohol, you may spend a long time trying to get off the bottle.”  This, to me, is a warning that drinking can be bad for you and that the authors of the study are not necessarily advocating that everyone go out and become “moderate drinkers.” 

The last paragraph goes on to conclude “That said, the new study provides the strongest evidence yet that moderate drinking is not only fun but good for you. So make mine a double.”   I’m confused.  I thought drinking was dangerous and could lead to a lot of other problems and screw up your life.  Isn’t that what the paragraph before this one said? 

Maybe this means I SHOULD share this with my students, just to see if they can help me decipher this.

Research calls into question “toning shoe” benefits

I remember not that long ago my mom was talking about these shoes and I thought they sounded way too good to be true.  My friend Ellen found this great article, and it’s definitely something I can see bringing to class and talking about with students.  The nice thing about this NPR report is that there are links within it to four different studies with contradictory results.  I haven’t looked carefully through all of the studies yet, but it might be a good exercise to share some of the methods with students and try to get students to reason about why the conclusions are so different. 

http://www.npr.org/templates/story/story.php?storyId=129027089

Thanks, Ellen!
