Technology-Enhanced Peer Review: Benefits and Implications of Providing
Pantelis M. Papadopoulos1, Thomas D. Lagkas, Stavros N. Demetriadis3, Educational Technology & Society, 2017/07/10
As the literature review makes clear, studies of online peer reviews are a dime a dozen. This one is a bit different, though. The proposition being tested here is whether students can improve their own self-assessment by participating in a peer review process. Not surprisingly, they can, even when no external reviewers review the student's work. Because the study is so small (n=36) the detailed statistical analysis of the results is purely an academic exercise. It would be interesting to see this work replicated with a significant population, but the mechanics of academic funding ensure we almost certainly never will.
We should not draw any generalizations from such a narrow study (a large third year undergraduate class (n = 142) and a small group (n = 19) of graduate students). But there's much that could be said of it, beginning with the definition of 'game' as (1) rewards for achieving goals (2) rapid feedback cycles (3) governance by rules, and (4) competition. This is obviously too narrow a definition (and it's debatable whether 'game' can be defined at all) and yet the usage here is too broad, and the 'game' involved awarding 10% of the course grade based on economic predictions (for example: announcements of the corproate tax rate). Not surprisingly students found the grading far too random and the effort disproportionate to the reward.
The E-nose probably won't be nose-shaped as illustrated in this article, but it will be ubiquitous. Noses are useful for a wide varoety of things - testing for bad meat, detecting smoke, identfying perfume, and tracking down bacon. The e-nose described here is made from carbon nanotibes; these are used because they bring memory and processing closer together. "As applications like machine learning become more widespread, computing’s data intensity is only growing." Related, from 2008: Electronic noses sniff success.
This item is for those ed tech writers (you know who you are) who jumped on gthe Pokemon Go bandwagon a year ago. Today, Pokeon Go is a wasteland, the Second Life of the AR world. Four out of five people have drop out of the game and this article explains why. The most telling of the reasons: there was no goal players were working toward, and it stopped being cool.
