I'm having a great deal of fun and excitement in experimenting the potential of videoblogging for professional purposes.
In particular, I have discovered in my own experience how easy and straightfoward is to publish homemade videos (YouTube had already taught us that, somehow), even when these videos might serve professional purposes, such as teaching and (formal or informal) learning.
Here is one of my latest experiences:
A master student sent me an email asking to clarify a technical issue on information architecture, to solve a design problem in his own design project. Instead of spending a great deal of time and energy in writing down the technical solutions, or editing a navigation scheme with the proper tools, I decided to send him a VIDEO ANSWER, which consisted in a 3 minutes video illustration of the proposed solution, with me talking over the shooting of a home-made paper sketch.
Efficiency for the instructor: preparing, shooting, (no editing), publishing a 3 minutes video took me 20 minutes (surely much less than a traditional technical email and subsequent asnwers for further clarification).
Learning reward for the student: the student wrote me the next days with an enthusiastic replay, thanking me for the clear and complete answer to the issue: he found the explanation helpful and illuminating to solve his problem.
On the basis of my limited experience, I am more and more convinced that:
* short videos can be very effective for explaining complex concepts (in brief) or for giving the big picture (setting connection). They may be effective for technical solutions (although more difficult) only with other kind of support (paper drawing, sketches, etc.) - see the experience of SciVee as example.
* the professional quality of the videos is not a necessary precondition for the effective communication of the message. Even "office-made" quality (SHORT - 2-3 mins) video can get the message through, as long as the student is committed and motivated to understand the content.
* videos make the communication with the students more lively and human - no doubt about that
* the effort for the teacher is minimum, with respect to traditional way of answering issues
* the learning effectiveness can be high, if content is relevant and well explained.
I'm eager to establish more short video-like material for our traditional and especially online courses, such as forums to post video-answers for the students's questions.
For shooting and publishing videos at low cost, I am finding HIPCAST a very useful online toolkit.
