Is there a cost? A critical reflection of TLT Symposium

As I continue to turn over the ideas and technology presented at the Teaching and Learning with Technology (TLT) symposium, I always have some point of concern. The keynote speaker gave the traits of "sticky" ideas, among them being simple, unexpected and concrete(sensory). My concern is rooted in technology magnifying the two latter, potentially at the detriment of the first. In other words, it seems that technology main be applied and cause shock and ah without bringing the learner to question. The questioning or huh moment as the keynote phrased it, is why unexpected is listed as a trait. Also, in trying to make an idea concrete by not only using sensory language but engaging multiple senses with multimedia or virtual reality(a favorite in the innovation challenge) is there not a risk of loosing the learner to sensory overload? In a sense, taking in all the details of the trees while missing the forest which is that learning goal we should be focused on helping our students achieve.

To clarify, I am not against integration of technology into teaching environments. I am merely cautioning that, as with all things, it can be mis- or over-applied producing unwanted effects. Most of the ideas presented in the innovation challenge as given in 5 min showed great potential to fall into the pitfalls mentioned above. This may be due merely to the brevity of the presentations not allowing for the full rational design to be articulated. There were technologies showed cased that touched on this idea of being careful and intentional in technology application. The first which comes to mind is the presentation on teaching design with addictive manufacturing (3-D printing). During the discussion of the learning goals for the 3-D printing courses at different levels (freshmen, upperclassmen and graduate students), the speaker made it clear that he needs to help students to see a 3-D printer as a manufacturing tool and active research area, not just a novel piece of tech. for printing figurines. Thus, he recognizes the ah and glitz of 3-D printing, but works to guide his students past that to learn its practical applicability in design as well as its limitations. This example speaks to the awareness of pitfalls mentioned above and intentionally structuring the course to avoid them.
