The joys of the econoblogosphere

With Johan Fourie celebrating his 100th blog post today, he reminded me of the joys of the econoblogosphere. Allow me to refer to his blog like Tyler Cowan would: it is self-recommending. Congratulations to Johan on this blogiversary.

Though we are still very few in South Africa, I want to recommend a number of my colleagues for readers to have a look at:
We all try to pitch in on the School's blog. My latest is on the environment and carbon taxes.

Lecturing in the digital age

Since I have returned to the office there is unfortunately less time to write blog posts than I had in May. However, I have been to some interesting meetings that inspire posts.

The past week two have been about lecturing in the digital age. If you are following this sort of thing you'll know that the internet is awash with posts on how Massive Online Open Courses is to bring about a revolution in higher education. In South Africa I have not met lots of people how worry about MOOCs, but everywhere there are academics moving towards the flipped classroom and more online learning. Administrators see distance learning (online) as a grow point.

In a meeting with a major publishing outfit, it was clear that not everyone is on the same page of the e-book. They want to "rethink textbook content delivery for the digital age". Many of my colleagues think about an e-textbook as the paper of the prescribed book, behind the gorilla glass of your tablet. It can be much more than that. It can be multimedia and interactive - even with specific feedback. This raises a bunch of questions. If you have multimedia and interactivity in the "book", what would be the point of those e-study guides that we hear we have to develop? Maybe you are already linking to videos or using the learning management system for electronic assessment - where would that fit into the story? If everything is going to be electronic, should it be in a "book", in different parts accessed through the LMS or packaged as a whole course at Udemy, iTunesU, or Coursera, or EdX? There is an interesting post on MOOCs as three kinds of LMS here. I suspect we will see lots of trail and error before we narrow this down to a few systems or products that work.

The publishers had an interesting answer to all this. They want to leverage all the book content that they have and add new digital content to create an ecosystem that we as academics (or our students) can subscribe to and then moderate and curate. They want to deliver this in a widget-based approach that can plug into your e-study guide or LMS or MOOC. You have to decide, do you want a core and then have all other resources available for students to explore (browser style)? Or do you want a core along with a defined path very specific advanced or remedial resources (app style)?

As cool as all this sounds I am worried that not enough lecturers are currently using a blended learning approach (a textbook, with a study guide, additional videos, or lecture capturing, along with pod casts, and on line tools, with some electronic assessment, in addition to lectures and class discussions) to know how to curate resources for the digital age. The technology mat be running far ahead of the pedagogy.

ECON-1 videos for the flipped classroom

This semester I used Explain Everything to add audio and annotations to PPT slides and make short videos for the flipped classroom. The idea is that the order of a contact session is flipped around: the students watch the videos as preparation and spend the time in class discussing and problem solving. I don't have to give a boring lecture and they don't have to listen to one - there is a video for that. My videos look like this:



This weekend I decided to have a quick look at the views that they got over the semester. The videos were uploaded on the module's eFundi site (our LMS) and on YouTube. The number clicks (don't know if they were viewed all the way through) on eFundi were:


EE_Movie_chap 1.mp4 752
EE_Movie_hst 1.mp4 772
EE_Movie_chap 2.1.mp4 294
EE_Movie_hst 2.1.mp4 445
EE_Movie_chap 2.2.mp4 230
EE_Movie_hst 2.2.mp4 331
EE_Movie_chap 2.3.mp4 202
EE_Movie_hst 2.3.mp4 390
EE_Movie_chap 3.mp4 154
EE_Movie_hst 3.mp4 449
EE_Movie_chap 4.1.mp4 203
EE_Movie_hst 4.1.mp4 387
EE_Movie_chap 4.2.mp4 132
EE_Movie_hst 4.2.mp4 306
EE_Movie_chap 4.3.mp4 115
EE_Movie_hst 4.3.mp4 261
EE_Movie_chap 4.4.mp4 96
EE_Movie_hst 4.4.mp4 274
EE_Movie_chap 7.1.mp4 142
EE_Movie_hst 7.1.mp4 274
EE_Movie_chap 7.2.mp4 106
EE_Movie_hst 7.2.mp4 248
EE_Movie_chap 7.3.mp4 88
EE_Movie_hst 7.3.mp4 206
EE_Movie_chap 7.4.mp4 69
EE_Movie_hst 7.4.mp4 187



EE_Movie_hst 7.5.mp4 212

That is a total of 7325 clicks and an average of 338 for the Afrikaans versions and 198 for the English versions. I hope to be able to split this between students in my group and those from other groups. For all the ECON111 students of around 1150 students, the average views are low, but my group was only 250. I wonder if the videos will be used much for revision before the exam.

Is it worth the effort? It is impossible to tell if it made much of a difference to student performance. We always have a look at the correlation between module marks and number of videos watched but that won't say anything about causation. I do think that it made a difference to the time spent in class. At least I enjoyed not giving a boring lecture and rather working through exercises and presenting interesting examples.
