Google for Educational Contexts

Interesting wishlist, over at tbarrett’s classroom ICT blog.

11 Google Apps Improvements for the Classroom | ICT in my Classroom.

In a way, Google is in a unique position in terms of creating the optimal set of classroom tools. And Google teams have an interest in educational projects (as made clear by Google for Educators, Google Summer of Code, Google Apps for schools…).
What seems to be missing is integration. Maybe Google is taking its time before integrating all of its services and apps. After all, the integration of Google Notebook and Google Bookmarks was fairly recent (and we can easily imagine a further integration with Google Reader). But some of us are a bit impatient. Or too enthusiastic about tools.

Because I just skimmed through the Google Chrome comicbook, I get to think that, maybe, Google is getting ready to integrate its tools in a neat way. Not specifically meant for schools but, in the end, an integrated Google platform can be developed into an education-specific set of applications.
After all, apart from Google Scholar, we’re talking about pretty much the same tools as those used outside of educational contexts.

What tools am I personally thinking about? Almost everything Google does or has done could be useful in educational contexts. From Google Apps (which includes Google Docs, Gmail, Google Sites, GTalk, Gcal…) to Google Books and Google Scholar or even Google Earth, Google Translate, and Google Maps. Not to mention OpenSocial, YouTube, Android, Blogger, Sketchup, Lively

Not that Google’s versions of all of these tools and services are inherently more appropriate for education than those developed outside of Google. But it’s clear that Google has an edge in terms of its technology portfolio. Can’t we just imagine a new kind of Learning Management System leveraging all the neat Google technologies and using a social networking model?

Educational contexts do have some specific requirements. Despite Google’s love affair with “openness,” schools typically require protection for different types of data. Some would also say that Google’s usual advertisement-supported model may be inappropriate for learning environments. So it might be a sign that Google does understand school-focused requirements that Google Apps are ad-free for students, faculty, and staff.

Ok, I’m thinking out loud. But isn’t this what wishlists are about?

Blogging the Drinking Age Debate

danah “zephoria” boyd is blogging about the conversation over drinking age in the United States.

apophenia: Dionysus and the Amethyst Initiative.

As boyd is relatively well-known, her blogging about this can have interesting effects in terms of generating “buzz.”

Her blogging the issue might help me as I follow my previous post up with some further comments. But that’ll have to wait. RERO!

What follows is my answer to boyd’s post, since trackbacks can be more powerful than blog comments.

You might enjoy IU researcher Ruth Engs‘s work on the topic.

A few concepts/expressions which could be useful in your future coverage…

  • “Moral entrepreneurs” (Howie Becker’s concept)
  • “Forbidden Fruit” (or cookie jar, but forbidden fruit works better for keyword searches, I think)
  • “Responsible Drinking” (a taboo expression in alcohol research in the United States but the concept which runs at the core of Amethyst)

Finally! A Drinking Age Debate

This may be more significant than people seem to assume: university and college administrators in the United States are discussing the potential effects of reverting the drinking age back to the age of maturity in their country (18 years-old). This Amethyst Initiative (blog), which was launched last month, may represent a turning point in not only alcohol policy but campus life in the United States.

This “story” has started to go around recently. And it happens to be one I care about. Read about this on Tuesday, while doing some random browsing.

College presidents seek drinking age debate – Life- msnbc.com.

And it’s coming back as a source of jokes:

College Presidents Rethinking Drinking Age | The Onion – America’s Finest News Source.

Though I may be a big fan of humour, I really hope that people can also take this issue seriously. For some reason, people in the United States tend to react to alcohol-related discussions with (possibly uneasy) humour. Fair enough, but there’s clearly a need for dispassionate, thoughtful, and serious discussion about the effects of current laws or the potential effects of new laws.

I have a lot of things to say about the issue but I’lll try to RERO it.

Now, obviously, the media coverage is typical “wedge issue” journalism. Which might well be working. In a way, I don’t care so much about the outcome of this journalistic coverage.

What I do care about, though, is that people may start discussing the social implications of alcohol prohibitions. It’s a much larger issue than the legal drinking age in the United States. I sincerely hope that it will be addressed, thanks in part to these administrators at well-known academic institutions.

Possibly the best person to talk about this is Indiana University’s Ruth Engs, professor of Applied Health Science. Engs has written extensively on the health effects of alcohol, with a special emphasis on the negative effects of the raised legal drinking age in the United States. She also has fascinating things to say about cultural dimensions of alcohol consumption, which happens to be a topic that I have been exploring on my own.

According to Engs, discussion of responsible drinking are quite rare in public events related to alcohol research in the United States. I personally get the impression that responsible drinking has become a taboo subject in those contexts. I certainly noticed this while living (as full-time faculty) on a “dry campus.”

It’s no secret that I care about responsible drinking. Part of this might have to do with the Éduc’alcool message which has been engrained in Quebeckers over the years: «la modération a bien meilleur goût» (“responsible drinking is more tasteful”). My strong impression is that at least some of those who wish for the drinking age in the United States to remain high share the opinion that, for adults, responsible drinking is more appropriate than binge drinking. They may think that any type of alcohol consumption has negative effects, but it’d be quite surprising if they actually preferred binge drinking over responsible drinking.

Where we seem to disagree is on the most effective strategies to reach the goal of responsible drinking among adults. IMHO, there is at the very least strong anecdotal evidence to show that increasing legal drinking age does very little to encourage responsible drinking. Unfortunately, with issues such as these, there’s a strong tendency for advocates of any position to dig for data supporting their claims. Stephen Jay Gould called this “advocacy masquerading as objectivity.” I may care strongly about the issue but I’m not really taking sides. After all, we’re talking about a country in which I’ve lived but in which I don’t have citizenship.

Let’s call a spade a “spade.” What’s at stake here is the National Minimum Drinking Age Act of 1984, which was pushed by the MADD lobby group (Mothers Against Drunk Driving). With all due respect to people involved in MADD and similar anti-alcohol advocacy groups, I have strong reservations as to some of their actions.

As a group, MADD is a “textbook example” of what sociologist Howard Becker has called “moral entrepreneurs.” In the United States, these moral entrepreneurs seem to be linked to what Ruth Engs calls clean living movements. What’s funny is that, though these movements may be linked to puritanism, Puritans themselves did use alcohol in their diet. So much so that the Mayflower landed in Plymouth Rock partly because of beer.

There’s a lot to say about this. From diverse perspectives. For instance, libertarians surely have interesting points about the NMDAA’s effects on state laws. Health researchers may talk about the difficulty of alcoholism prevention when responsible drinking is left undiscussed. Teetotalers and Muslims may see this as an opportunity to encourage complete abstinence from drinking. Road safety specialists may have important points to make about diverse ways to prevent drunk driving. Law researchers may warn us about the dangers to the legal system inherent to laws which are systematically broken by the majority of the population. Border officers may have some interesting data as to the “alcohol tourism” related to college drinking. University and college students clearly have diverse approaches to the subject, contrary to what the media coverage (especially the visuals used) seem to indicate.

My own perspective is quite specific. As a very responsible drinker. As a Quebecker of recent European origin. As a compulsive pedestrian. As an ethnographer interested in craft beer culture in North America. As a homebrewer. And, more importantly, as a university instructor who, like Barrett Seaman, has noticed widely different situations on university campuses in the United States and Canada.

Simply put, it seems quite likely that widespread binge drinking on university campuses has originated on U.S. campuses since 1984 and that the trend is currently spilling over to affect some campuses outside of the United States. College binge drinking is not a global problem. Nor is it a problem entirely specific to the United States. But the influence of U.S. college and university campus culture in other parts of the world often comes with binge drinking.

Apart from the fact that I find binge drinking to be extremely detrimental to physical and mental health, my observation is about campus life in general. AFAICT, on university and college campuses where alcohol consumption by a significant proportion of the student population is illegal, illicit alcohol consumption pushes younger students outside of the broader campus life. This self-segregation makes for a very uncomfortable learning and teaching context. In other words, the fact that students hide in fraternity houses or off-campus locations to binge drink may have the same socialization effects as regular campus life elsewhere on the planet, but the isolation of these people is a net loss in terms of generating an academic environment which is nurturing and tolerant.

To be clear: I’m not saying that the legal drinking age in the United States needs, of necessity,  be brought back to 18 years-old as it was in several States until fairly recently. I’m not even saying that States should necessarily be allowed to set their own drinking age laws. I simply wish for this debate on legal drinking age to happen. Actually, I hope that there will be real, thoughtful dialogue on the issue.

Really, it’s the tasteful thing to do.

Thought Streams about Online Literacy

Interestingly enough, in the last several days, at least five unrelated items of online content have made me think about what I’d call “online literacy.” Not too surprising a co-occurrence, given the feeds I follow, but I think still interesting. Especially because different perspectives were behind these items and the ways I was led to them.

Here are the five items I most directly connect with my streams of thought about online literacy, during the past few days.

Several items in my streams of thoughts on online literacy have found their way into a Moodle Lounge thread where they were mostly connected with the future of textbooks.

My notion of “online literacy” might be idiosyncratic. The concept, to me, relates to “media literacy” which (as far as I can tell) refers to the efficient use of a set of conceptual tools meant to help in approaching media items from the perspective of critical thinking and intellectual engagement. “Online literacy” would be the same thing applied to the Internet in general. One element specific to online literacy, I would argue, is that some basic principles of the Internet (including its decentralized character) make the critical/engaged approach very prominent. Simply put, the way the ‘Net is set up almost forces people to apply critical thinking to what they read, view, watch, or listen to, online. In something of a “cool medium” sense, the ‘Net also encourages active engagement in the material (though for reasons different from McLuhan’s description of medium coolness).

Furthermore, I tend to associate “book literacy” with modernity while “online literacy” seems quite compatible with orality which is itself typical of both post- and pre-modernity. I’m guessing this last point seems exceedingly weird to a number of people, but it really seems to fit in a larger scheme.

There are ways to discuss these issues which are more tech-friendly or geeky. Synchronous communication, many-to-many relationships, peer-to-peer (file) sharing, distributed processing… But as I think out loud, these concepts are mostly in the background.

My basic claim in all of this is that, regardless of how positive we think the move toward online content and away from mass-produced books, it’s important to train ourselves (and others) to gain a level of savviness in the online world. This form of online literacy is especially important with students because of their active engagement in the construction of knowledge.

Enthused Tech

Yesterday, I held a WiZiQ session on the use of online tech in higher education:

Enthusing Higher Education: Getting Universities and Colleges to Play with Online Tools and Services

Slideshare

[slideshare id=528283&doc=enthusinghighered-1217010739916970-8&w=425]

(Full multimedia recording available here)

During the session, Nellie Deutsch shared the following link:

Diffusion of Innovations, by Everett Rogers (1995)

Haven’t read Rogers’s book but it sounds like a contextually easy to understand version of ideas which have been quite clear in Boasian disciplines (cultural anthropology, folkloristics, cultural ecology…) for a while. But, in this sometimes obsessive quest for innovation, it might in fact be useful to go back to basic ideas about the social mechanisms which can be observed in the adoption of new tools and techniques. It’s in fact the thinking behind this relatively recent blogpost of mine:

Technology Adoption and Active Reading

My emphasis during the WiZiQ session was on enthusiasm. I tend to think a lot about occasions in which, thinking about possibilities afforded technology relates to people getting “psyched up.” In a way, this is exactly how I can define myself as a tech enthusiast: I get easy psyched up in the context of discussions about technology.

What’s funny is that I’m no gadget freak. I don’t care about the tool. I just love to dream up possibilities. And I sincerely think that I’m not alone. We might even guess that a similar dream-induced excitement animates true gadget freaks, who must have the latest tool. Early adopters are a big part of geek culture and, though still small, geek culture is still a niche.

Because I know I’ll keep on talking about these things on other occasions, I can “leave it at that,” for now.

RERO‘s my battle cry.

Patent Filing the Future of Instructional Podcasts

Glad to see Apple thinking about some new ways to produce and distribute podcasts.

AppleInsider | Apple filing takes Podcasts to the next level

It’s quite possible that this patent filing may not lead to anything concrete but the very fact that Apple devotes some time to the issue could lead to interesting things. In fact, other manufacturers may be motivated to move in this space and this might have powerful effects on educational technology.

Planting Landmines

The ever-thoughtful Carl Dyke graciously provided me with this expression as a way to talk about edubloggers might call “lifelong learning.” Part of teaching is about exposing students to some notions which may have radical effects later on in their lives. This is especially true for us in social sciences as some of the things we discuss not only go against the grain of some well-ingrained notions but also connect with very intimate ideas people may hold.

I think the example we were using was the construction of ideas about Nation-States/Countries, Citizenship, and Democracy. Lots of people (and, clearly, most of our students) assume that the ideas we have about States and governance are continuous and even equivalent with those held by any group at any point of history. Simply put, national identity is taken as a “natural” idea. Which makes it hard for some people to discuss such issues in a historical perspective. This is one reason I enjoyed Appiah’s “Golden Nugget” idea so much (not to mention that his talk was quite entertaining). It’s a way to put the very notion of “Civilization” in perspective (without using an evolutionary model). Carl also provided me with references to Eugen Weber and to the Taviani Brothers’ Padre Padrone. We could even use scene 3 of Monty Python and the Holy Grail (video). All of these things are, in my mind, landmines. Actually, “mind landmines” or, erm, “landminds.” (Should I get a trademark?)

Of course, literature on nationalism (Benedict Anderson, Terence Ranger, Eric Hobsbawm, etc.) can also be used. Personally, I tend to like work on similar subjects by ethnographers like Regina Bendix and Kelly Askew.

Those “landminds” are only triggered when people start really looking into issues lying underneath society and politics. But when they explode, these landminds can be quite transformative. As per the deadly effects of the explosives from which they’re inspired, these landminds destroy some apparently strong intellectual models.

So, although I see landmines as a major problem, I do see part of my work as “planting landminds.”

Much less positive than the usual “planting the seeds of knowledge” metaphors, but also much more powerful.

Selling Myself Long

Been attending sessions by Meri Aaron Walker about online methods to get paid for our expertise. Meri coaches teachers about those issues.

MAWSTOOLBOX.COM

There’s also a LearnHub “course”: Jumpstart Your Online Teaching Career.

Some notes, on my own thinking about monetization of expertise. Still draft-like, but RERO is my battle cry.

Some obstacles to my selling expertise:

  • My “oral personality.”
  • The position on open/free knowledge in academia and elsewhere.
  • My emphasis on friendship and personal rapport.
  • My abilities as an employee instead of a “boss.”
  • Difficulty in assessing the value of my expertise.
  • The fact that other people have the same expertise that I think I have.
  • High stakes (though this can be decreased, in some contexts).
  • My distaste for competition/competitiveness.
  • Difficulty at selling and advertising myself (despite my social capital).
  • Being a creative generalist instead of a specialist.

Despite all these obstacles, I have been thinking about selling my services online.

One reason is that I really do enjoy teaching. As I keep saying, teaching is my hobby (when I get paid, it’s to learn how to interact with other learners and to set up learning contexts).

In fact, I enjoy almost everything in teaching (the major exception being grading/evaluating). From holding office hours and lecturing to facilitating discussions and answering questions through email. Teaching, for me, is deeply satisfying and I think that learning situations which imply the role of a teacher still make a lot of sense. I also like more informal learning situations and I even try to make my courses more similar to informal teaching. But I still find specific value in a “teaching and learning” system.

Some people seem to assume that teaching a course is the same thing as “selling expertise.” My perspective on learning revolves to a large extent on the difference between teaching and “selling expertise.” One part is that I find a difference between selling a product or process and getting paid in a broader transaction which does involve exchange about knowledge but which isn’t restricted to that exchange. Another part is that I don’t see teachers as specialists imparting their wisdom to eager masses. I see knowledge as being constructed in diverse situations, including formal and informal learning. Expertise is often an obstacle in the kind of teaching I’m interested in!

Funnily enough, I don’t tend to think of expertise as something that is easily measurable or transmissible. Those who study expertise have ways to assess something which is related to “being an expert,” especially in the case of observable skills (many of those are about “playing,” actually: chess, baseball, piano…). My personal perspective on expertise tends to be broader, more fluid. Similar to experience, but with more of a conscious approach to learning.

There also seems to be a major difference between “breadth of expertise” and “topics you can teach.” You don’t necessarily need to be very efficient at some task to help someone learn to do it. In fact, in some cases, being proficient in a domain is an obstacle to teaching in that domain, since expertise is so ingrained as to be very difficult to retrieve consciously.

This is close to “do what I say, not what I do.” I even think that it can be quite effective to actually instruct people without direct experience of these instructions. Similar to consulting, actually. Some people easily disagree with this point and some people tease teachers about “doing vs. teaching.” But we teachers do have a number of ways to respond, some of them snarkier than others. And though I disagree with several parts of his attitude, I quite like this short monologue by Taylor Mali about What Teachers Make.

Another reason I might “sell my expertise” is that I genuinely enjoy sharing my expertise. I usually provide it for free, but I can possibly relate to the value argument. I don’t feel so tied to social systems based on market economy (socialist, capitalist, communist…) but I have to make do.

Another link to “selling expertise” is more disciplinary. As an ethnographer, I enjoy being a “cultural translator.” of sorts. And, in some cases, my expertise in some domains is more of a translation from specialized speech into laypeople’s terms. I’m actually not very efficient at translating utterances from one language to another. But my habit of navigating between different “worlds” makes it possible for me to bridge gaps, cross bridges, serve as mediator, explain something fairly “esoteric” to an outsider. Close to popularization.

So, I’ve been thinking about what can be paid in such contexts which give prominence to expertise. Tutoring, homework help, consulting, coaching, advice, recommendation, writing, communicating, producing content…

And, finally, I’ve been thinking about my domains of expertise. As a “Jack of All Trades,” I can list a lot of those. My level of expertise varies greatly between them and I’m clearly a “Master of None.” In fact, some of them are merely from personal experience or even anecdotal evidence. Some are skills I’ve been told I have. But I’d still feel comfortable helping others with all of them.

I’m funny that way.

Visualizing Touch Devices in Education

Took me a while before I watched this concept video about iPhone use on campus.

Connected: The Movie – Abilene Christian University

Sure, it’s a bit campy. Sure, some features aren’t available on the iPhone yet. But the basic concepts are pretty much what I had in mind.

Among things I like in the video:

  • The very notion of student empowerment runs at the centre of it.
  • Many of the class-related applications presented show an interest in the constructivist dimensions of learning.
  • Material is made available before class. Face-to-face time is for engaging in the material, not rehashing it.
  • The technology is presented as a way to ease the bureaucratic aspects of university life, relieving a burden on students (and, presumably, on everyone else involved).
  • The “iPhone as ID” concept is simple yet powerful, in context.
  • Social networks (namely Facebook and MySpace, in the video) are embedded in the campus experience.
  • Blended learning (called “hybrid” in the video) is conceived as an option, not as an obligation.
  • Use of the technology is specifically perceived as going beyond geek culture.
  • The scenarios (use cases) are quite realistic in terms of typical campus life in the United States.
  • While “getting an iPhone” is mentioned as a perk, it’s perfectly possible to imagine technology as a levelling factor with educational institutions, lowering some costs while raising the bar for pedagogical standards.
  • The shift from “eLearning” to “mLearning” is rather obvious.
  • ACU already does iTunes U.
  • The video is released under a Creative Commons license.

Of course, there are many directions things can go, from here. Not all of them are in line with the ACU dream scenario. But I’m quite hope judging from some apparently random facts: that Apple may sell iPhones through universities, that Apple has plans for iPhone use on campuses,  that many of the “enterprise features” of iPhone 2.0 could work in institutions of higher education, that the Steve Jobs keynote made several mentions of education, that Apple bundles iPod touch with Macs, that the OLPC XOXO is now conceived more as a touch handheld than as a laptop, that (although delayed) Google’s Android platform can participate in the same usage scenarios, and that browser-based computing apparently has a bright future.

Edupunk Manifesto?

Noticed, just yesterday, that a number of unusual suspects of some online educational circles were using Edupunk as a way to identify a major movement toward openness in educational material. This video doesn’t “say it all” but it can help.

Changing Expectations

[blip.tv ?posts_id=965966&dest=-1]

Like Lindsea, I wish more diverse voices were heard. Bakhtin FTW!

Unlike Lindsea, I don’t see it as mainly a generational thing or a “teacher vs. student” issue. In fact, I’m hoping that the social movements labelled by the term “edupunk” will move beyond those issues into a broader phenomenon.

The age/generation component is still interesting, to a Post-Buster like me. Baby Boomers are still the primary target of Punk. Lindsea even talks about Boomer classics:

Don’t you teachers remember when you were young? Hippies? Protesters? Implementers of change? Controllers of the cool, anti-establishment, nonconformist underground culture?

Baby Busters (the earlier part of the so-called “GenX”) have long been anti-Boomers. Not that everyone born during those years readily identify themselves with that “Generation.” But in terms of identity negotiation, the “Us/Them” often follows a concept of generational divide.

But I sincerely hope we can go way beyond age and generation. After all, there are learners of all ages, some of them older than their “teachers” (formally named or not).

Call me a teacher, if you really must. But, please, could we listen to diverse voices without labelling their sources?
