MOOCing around: Week 1 Ending

Group of FishIt’s so interesting to take a class in a subject I haven’t taken in a looooooooong time (statistics).

I’m in a MOOC with 74,999 other students. I’ve used the Khan Academy videos on statistics to help me (and I’m just finishing week one!). I finished the video Koala Sleeping in Treelectures and the first quiz (no score yet) and I’m working on the first assignment due tomorrow (Tuesday, 9/11).  It’s taken me at least 4 hours so far.

Fun, yet daunting. I plan to finish, even if I have to pull a few all-nighters!

According to Kevin Carey, in the article Into the Future With MOOC’s in the Chronicle of Higher Education, MOOCs represent the future of education. He refers to his own experience in a mega-sized face to face economics course as evidence that mass-produced education is not new and that it can be more cost-efficient.

I agree, but only to a certain extent. MOOCs are useful, even for credit (although I’m not taking the stats course for credit). However, the structure of MOOCs must Teacher and classchange to incorporate critical thinking and higher order skills. I think MOOCs are great for those of us who want access to learning…period. I want MOOC creators to keep expanding their subjects and use. For those who need more hands on and for those subjects that require more analysis, MOOCs will not work. Not yet. Not without a mass infusion of ….. je ne sais quoiCalculator & Math Symbolss….a more in depth relationship among  learners, instructors and the critical thinking skills/content.

How will I know whether I’ve learned from this MOOC? There are tests, assignments and (my goal) my increased comfort with and ability to read articles that include statistical analyses. And isn’t that truly what learning is about?

Twearning: And the Learning Goes On…..Exam 2

In assessment of learning, Education, how people learn, teaching with technology, technology, tests on April 10, 2012 at 2:11 pm

Good news. Look at the chart! Twitter in the classroom seems to work; even with the more complicated materials. This chart shows that the spring 2012 grades lean toward As and Bs.


The second exam is more difficult than the first because it requires more application of concepts to scenarios and less of the basics. You can see from the chart that in Spring 2012 there were more As (2, instead of none in Spring 2011).  There were an equal number of “Bs” in Spring 2011 and Spring 2012. There were more Cs in Spring 2012 then Spring 2011 (7, instead of 4 in Spring 2011) and fewer Ds and Fs. This result is consistent with the results of Exam 1.

So, what does this mean? Grades are one measure of determining whether learning has occurred. To the extent that exam scores improved over last year, I have evidence that using Twitter may have had an impact. As I noted in the earlier post, though, this result may not be terribly surprising in light of the fact that requiring Twitter required an extra review of the material (because students, in groups, had to summarize the weekly tweets and present those summaries to the class).

Then again, the fact that I permitted students to have their cell phones cell phoneavailable during class demonstrates that, at least at this level, and at least with a small class, that it did not hurt overall class performance on exams. It is equivalent too, in the old days (when I was a student), to students reading a newspaper reading_a_newspaperduring class (some faculty permitted it, some didn’t) or passing notes to other students. Students are distracted, at least for that time, but it didn’t hurt their overall performance.

Keep tuning in: students must turn in ePortfolios and final projects later….

Oh, No, We Won’t Go-Academia and Digital Information

In Education, institutional responsibilities, tests on April 2, 2012 at 9:06 am

Digital information everywhere. Digital books. Digital images. Digital videos. Digital…but not in the academy. In the academy we still place extraordinary attention to print media as the basis for tenure and promotion. We ignore the digital revolution that has occurred all around us.


Instead, the structures of universities often fail to reward and champion digital innovators, particularly in guidelines for promotion and authorship that privilege traditional scholarship.

If we do not create mechanisms that reward faculty and students who form digital-research communities, then innovation may bypass universities entirely, putting us at risk of falling behind institutes, private companies, and even individuals.

Randolph Hall, Vice President for Research at USC, made this point in a recent article titled Scholarship, Liberated from Paper at Last in the Chronicle of Higher Education. He notes that after discussion with faculty at his institution, the faculty agreed to include revise the process for tenure and promotion to include recognition of the value of a faculty member’s digital research.

Change occurs slowly in academic institutions. I’ve made that point in other posts. You would think academia would be at the forefront of forging new directions and new research areas. You would think that academia would be the first to devise new ways of thinking about how people learn and in fostering an environment of analyzing tradition and also challenging tradition. If you thought that, you would be wrong. Academia is tied down to traditional methods despite the progress in the rest of society. For example, information forwarded for academic tenure and review at my university is still wedded to paper documents. The process includes, for example, instructions on how the faculty member should label his or her [paper] binder. So, even though all the documents are created electronically, they must be converted to paper for the review. ePortfolios (see .e.g. Trent Babson’s ePortfolio links) or programs like LiveBinder could allow for that same information to be provided in electronic form.

u_s__supreme_courtWhy are academic institutions wedded to paper? Paper is perceived as more permanent; however there are ways to preserve electronic documents. And if the courts permit electronic filing of documents (see e.g. e-filing of electronic briefs) where finances and other matters are at stake, then our University should recognize the value of electronic documents. Also, if the concern is the rigor of the scholarship, public exposure and peer review can help to increase rigor. Research that is available to the public helps to promote additional learning for the public and for the researcher. It could also lead to additional research and creative use of that research.

So, as noted in the Hall article, academia must recognize the value of digital research. Hall notes that Universities like Harvard have createst tubested ways to disseminate research to the public more quickly so that others can read and comment on it. My own experience in posting on SlideShare and on this blog has allowed me to present research findings, (e.g. results of using Twitter in the classroom) to many others. I have had 80 views on a presentation on plagiarism-far more than attended the actual presentation. And with more exposure, I have more opportunity to learn more, test my research and work to make it better.  That’s much more exposure than posting the article in a paper journal that requires that people go to a physical library to access it.

Twearning-First Exam Results Updated

In assessment of learning, critical thinking, Education, how people learn, innovation in teaching, teaching, teaching with technology on March 21, 2012 at 12:14 pm

I’m using Twitter in my class this semester. This class is composed of 18 students taking a required course in the Ethical and Regulatory Environment of Sports Marketing. Students range from second semester juniors to graduating seniors. Students must use Twitter to post tweets during class, post two tweets about course content (textbook readings or current events) outside class and prepare group reports summarizing the weekly tweets and present those summaries in class. This means, that during the class, students have laptops, smart phones and other electronic devices open during class.

I haven’t analyzed the data on the number of tweets per week, but my estimate is an average of nearly 50 tweets total each week (some students forget). I’ve found that the weekly summaries are good reinforcements and these summarizes also give me the opportunity to correct any misconceptions that arise from the tweets.

In the earlier post, I briefly compared the exam results between the Spring 2011 and Spring 2012 courses.  I had only the results of the objective portion of the exam, so it was a preliminary comparison.

After completing the full exam, I’m now comparing the results this semester to the results last spring for this course. The following is the chart comparing the grade distribution.

Online Graphing

The results remain positive.

Grade distribution

There was a larger number of As and Bs in the Spring 2012 course (10/18 or 56%) compared to the Spring 2011 course (5/18 or 23%).  Interestingly, the number of Ds and Fs remained the same. The shift in grades was in the number of Cs: down from 33.3% in Spring 2011 to 16.5% in Spring 2012. There was a greater percentage of As in the Spring 2012 class (an increase of 400%).

Interpretation of results

These are small classes so although these results are promising, this doesn’t mean they can be translated to larger courses.

It appears that the use of Twitter in this way fostered student active engagement (I conducted a pre-survey and I’ll conduct a post-survey on engagement to determine whether that the students felt that Twitter use improved engagement with the course and the material.).  Twitter use apparently fostered  more focus on the course material-students were actually engaged in taking notes in class (at least to send the tweet during class and then the two tweets outside of class) and reviewing the material (at least when the groups submitted and presented the group summary). That fits with more traditional theories on learning that the more you engage with the material, the more you will remember.

A portion of the exam was answers to essay questions. I graded those answers anonymously, but I could have been biased toward students doing well.

One interesting conclusion from this small amount of data was that use of laptops & cell phones in class didn’t decrease performance. Even if Twitter use wasn’t the cause of the increase in As and Bs, it doesn’t appear that it had a negative impact on performance. Because this was a small class, and because I typically walk around when I teach, it may be that students were more careful about using the laptops and phones appropriately than in another, larger class.

There are undoubtedly other, better measures to assess impact-I’m using a a simple one. Behavior analysis through using observers who rate behavior, would probably be more accurate in addition to the exam results, but this is the beginning of this journey, not the end, so stay tuned!
