📑 Video in Situ
There are a few programs playing with instructional video in really interesting ways. At OU, we have moved away from back-of-the-class lecture capture, producing instead sets of short videos where the instructor explains the key concepts. We have built a light screen so instructors can write like the would on a white board while looking into the camera and talking to the students. I think this takes us passed the poor substitution standard and into augmentation.
John Stewart reflects on the way in which the La Blogothèque website / YouTube channel redefines the video experience, creating new and unique possibilities. He wonders if the same changes could be incorporated into the filming of educational videos for blended and online courses, in particular, the possibilities for capturing field work. I have written about the Take Away Shows before, discussing the possibility of redefining the whole pedagogical experience. The reference to capturing field work reminds me of an early Google Glass exercise capturing CERN.
William Softky unpacks the question as to whether vinyl is better than digital? This includes providing a history of recorded sound, from the phonograph, to the radio, to stereo. He suggests the difference relates to the how and what of listening:
This all comes back to the sensory experience of how the body picks up vibrations:
Softky explains that the digital sampling and compression associated with CD’s and MP3’s denies the information resolution the nervous system cares about. This is where analogue technologies are still superior.
In response to all this, Softky predicts the emergence of three new technologies that could change the world by reconnecting people with sound:
Devices that quantify sound the right way
Microtime recording and stereo
Micropresence = microtime telepresence
Alternatively, we could see a return to more ‘acoustic’ music concerts:
This reminds me of intimacy of La Blogothèque.
For more on sound and technology, Geoffrey Morrison discusses the problem with digital compression. This is also something discussed on Switched on Pop in an interview with Dallas Taylor.
