Google Wave, which combines email, instant messaging and wiki-style editing will go on public trial today. The search giant hopes the tool, described as "how e-mail would look if it were invented today", will transform how people communicate online.

Agh! Not another way to communicate! I can't even remember my passwords to all these things! I can't even remember I have a Facebook account until someone "friends" me! What happened to isolation and Transcendentalism? Needing to read Walden in the woods alone right now...

I thought this was interesting following our discussion about Sherry Turkle yesterday. Robots assessing "risky behavior?" A South Korean prison will begin a month-long trial to see if robots make good prison guards. (Image Credit: Asian Forum For Corrections) The BBC reports that a jail in Pohang, South Korea, will soon begin a one-month trial of three new robots, which will be there in a support capacity to monitor for "abnormal behavior."

This paper presents the first experimental evidence on the effects of live versus internet media of instruction. Students in a large introductory microeconomics course at a major research university were randomly assigned to live lectures versus watching these same lectures in an internet setting, where all other factors (e.g., instruction, supplemental materials) were the same. Counter to the conclusions drawn by a recent U.S. Department of Education meta-analysis of non-experimental analyses of internet instruction in higher education, we find modest evidence that live-only instruction dominates internet instruction. These results are particularly strong for Hispanic students, male students, and lower-achieving students. We also provide suggestions for future experimentation in other settings.

The authors are very misleading in their claim that this study is the first on live versus internet. There is a huge literature on this topic stretching back decades. The claims about the generalizability of the study are also very suspect.

Chris, I think the authors are claiming it is the first experimental trial where participants were randomly assigned to a treatment or control condition. They contrast their study with the DOE meta-analysis, which I don't think includes experimental studies--at least as experiments are defined within econometrics. My problem with the study is that they are aren't really comparing live vs. internet so much as live vs. recorded video. They are very careful to not take advantage of any of the potential affordances of internet mediated instruction, except broadcasting a lecture, to preserve the "purity" of their experiment. Of course, that's not a terribly interesting experiment. The more interesting experiments, which they deride as "not apples-to-apples," is to compare a traditional lecture format with an online course that takes full advantage of the affordances of the internet. These studies would confound the carefully balanced design of an apples-to-apples comparison, but no serious education technologist thinks we should just record all the lectures and post them...

This post adds value to the previous one regarding the use of FB in the classroom. I'm thinking of using this tool for a project. Let me know your thoughts if you trial it. Cheers
