What is 8 @ $1? The number of good reasons for capturing lectures and the cost for doing so

Though lecture capturing may not be the most innovative or student activating technology, recent studies of basic lecture capturing at Aarhus University indicate that several affordances can be realised – this even at a low cost. Three different science modules have now been using lecture capturing and each time the technology actualised additional educational affordances such as more flexibility, support for distance education, high student satisfaction, support for strategic learning, the use of multimedia learning materials etc. At least 7 affordances and no significant downsides could be identified while marginal costs per module per student in large-scale subjects were as little as approximately $1.

An example of good use of lecture capturing. The teacher makes a live demo of how to program. The students can subsequently view the explanation again in their own pace.

Further details can be found in my recent article ‘8 Good Reasons for Reconsidering Lecture Capturing (of which Cost-Effectiveness is One)’ which soon will be available in the AACE’s Ed/ITLib and presented at the Global Learn 2012 conference,  Nov. 6-8. Slides and the related discussion can be found here.

Three easy ways to engage and motivate your students —yes, I did say ‘easy’ :-)

  • Easy way #1 | Have students solve problems as a group, and write clicker questions for each other – See how Ditlev Brodersen at the Department of Molecular Biology and Genetics at Aarhus University, Denmark, tried this out in a course on Advanced Biochemistry (you will need to download the full report as PDF to read more about what he did).
  • Easy way #2 | Organize ignite talk sessions with your students – As a group, or as individuals, have them prepare 5-minute talks with 20 slides total, which automatically move forward every 15 seconds. They’re like ‘mini-TED talks’: both focused and engaging. You can think of prices for best speakers, best presenters, best visual artists, etc and have the students in the audience be part of the jury. Or make it the format of your final evaluation, but still practice that format for presenting in class, perhaps also using video recording for helping with improvement.
  • Easy way #3 | Assign collaborative tasks through Google Drive and MindMeister  - Group work in general is quite engaging and motivating, which can both contribute to increasing learning. But group work often goes wrong –one student talks too much, another too little, or students lose track of time– unless clear guidelines and rules are followed.  One of these rules is to make sure the group keeps track of its progress and produces a concrete output. Google Drive (former but expanded Google Docs) makes it quite convenient to organize collaborative tasks with students. Google Drive now incorporates MindMeister, which can enable students to create mind maps that connect to their Google Drive documents. The whole Google Drive+MindMeister suite is also now incorporated into the brand new Chromebook Education pack, which, after Apple’s iPad, seems to be yet another strategy to supplant PCs in schools.

Alright, just three easy ways, as I promised – easy in the sense that they won’t cost you anything (you don’t even have to use clickers) and they correspond mostly to slight but significant adjustments of current teaching practices. Although it might take some time at first to get set up –as when pursuing any new avenue– think about the resulting engagement and motivation of your students, and how rewarding that will be for both you and your students!

But did those ways appear as being ‘easy’ to you just as I announced it? Were you more like “yeah, that’s totally easy, I can do that no problem” or more like “oh, no way – I can’t use clickers/ignite talks/MindMeister that easily in my exercise sessions”? So, were you, or not, somewhat turned off after the “easy” announcement that was meant to be comforting?

If you were a bit turned off, or felt under pressure, or were looking for excuses why this would not work for you, don’t worry – that’s just a normal reaction to hearing the word “easy”. As teachers we like to use that word with our students to appear comforting and reassuring. But most likely what we achieve actually is to scare our students or have them feel bad about themselves (see number 24 on the list). Telling them for example a particular concept or assignment is “easy” will often make them feel they can no longer just ask any question about anything now, and they were probably not very eager to doing so to begin with… They also don’t want to say something that could reveal they are missing a point, which would be just like admitting the task was not “easy” to them, in front of you and all their peers!

So stay away from the “easy” word –I promise I will do the same, even though these three ways are easy…

Maybe ‘talking head’ is not all bad?

Developing online and blended learning can be a comprehensive task. The teacher has to rethink his/her communication of curriculum, the students have to learn the new way of studying, and materials have to be developed and distributed. At least that is how it oftentimes is organised. However, what if we can use a well-known way of teaching and learning and just mediate that?

Much science teaching is carried out as lectures supplemented with exercises and assignments. The exercises may require time in lab and interaction, but the lectures are oftentimes one-way presentations where the teacher presents the theory in an auditorium. The student sits passively and listens to the presentation and this way – sometimes rather unsuccessfully – tries to acquire the presented knowledge. Why not simply record such lectures and distribute them over the Internet and at least provide some degree of flexibility?

A study carried at Aarhus University among math students on a retraining programme in 2011 showed a high satisfaction with ‘plain’ video recordings of lectures and a relatively high usage. The recordings were made in order to minimise time on campus and limit travelling activity by replacing half of lectures by videos and at the same time to offer an opportunity for content review, practising performing mathematical proofs, and preparing for the oral exam. Each student repeated the videos 2-3 times and approximately 30-40 % of the plays were around the oral exam or re-examination. The study indicated that the students did just as well as the regular daytime students though exposed to recordings instead of on-campus lectures.

In other words; lecture captures may not result in better learning, but do they make things worse? Not really – and in this case they even provided flexibility in time, place, and pace.

You can learn more about the study at this year’s EdMedia conference in Denver – where I will be giving a presentation on the topic – and in the paper ‘Talking Head is not Dead: Facilitating Online Learning using Basic Lecture Capturing‘ (Godsk & Dalsgaard, 2012) – soon available in AACE’s Ed/ITLib. Additionally, you can read more about (primarily) the benefits of lecture capturing in EDUCAUSE’s ‘7 things you should know about…’ (EDUCAUSE, 2008)
