[CSG Fall 2008] Collaboration and Social Technologies – eLearning

I’m at Cornell for the Common Solutions Group Meeting.

First part of workshop will deal with e-learning, afternoon with collaboration tools.

Anne Moore from Va Tech is talking about categories for thinking about evaluation of success for learning technologies. She starts by talking about the 1999 National Academies report on Being Fluent in Information Technology. One point they made is when you look at critical thinking and sustained reasoning, you need to look at those skills in an environment that is technology assisted, but in a domain. The report hasn’t been largely read or applied.

Being able to assess higher level of skills is becoming more important due to the emphasis on accountability. We’ve been more focused on inputs, rather than outcomes – academic institutions are largely still not focused on being able to demonstrate learning outcomes.

Joel Smith from Carnegie Mellon talks about the Open Learning Initiative at CMU. He call this Scientifically Informed Digital Learning Interventions.

The challenge is to design and build fully web-based courses which by rigorous assessments are proven to be as good or better than traditional teaching methods. There are multiple ways of building those courses.

Why? Increased access, improved effectiveness, providing flexibility, contain costs.

The current structure of higher ed presents substantial roadblocks to the application of proven results and methodologies from the learning sciences. We depend on individual faculty to develop courses – before we had lots of info from cognitive and learning sciences teaching may have been more of an art than a science. But it’s not fair to saddle each faculty with having to know all that cognitives science. There’s an opportunity in e-learning interventions, developed by collaborations of experts, to embed the knowledge of learning sciences to make the practice more effective.

OLI Guiding Assumptions:

- Digitial learning interventions can make a significant different in learning outcomes.

- Designs grounded in learning theory and evaluation have the best chance of achieving the goal.

- A possibe, acceptabe outcome is failure or mixed failures and successes – not promoting technology for its own sake.

- Formative assessment iwll be a major feature (and cost component, like 40% of budget) of designs and improvement of courses.

- IT staff working with faculty is too limited a partnership – learning scientists, HCI experts, and assessment experts must be part of design, development, production, and iterative improvement.

OLI courses are available in http://www.cmu.edu/oli . Don’t expect an “OCW experience” this project has a different set of goals than OCW. These are full courses, designed for real learners. “Clicking around” will be unsatisfying: these interventions are designed to support a novice learner in acquiring knowledge workin on their own.

Key elements in OLI courses:

- Theory based -

Builds on prior informal knowledge. We know that building on informal knowledge helps people learn faster. Example is an economics course that has exercises that builds on student knowledge of markets based on eBay. Includes cognitive tutors that have just a few node trees on giving feedback of correct or incorrect decisions.

Provides immediate feedback in the problem solving context – midterm and final is hardly immediate or rich.

Promote autheticity, flexibility, and applicability. Real world problems, which are messy and not clear-cut, is much more effective in promoting better learning outcomes.

- Feedback loops (The killer app) – courses record student activity for robust feedback mechanisms. Can feed info back into database or to faculty – this can change the nature of education. Can also give feedback to course designers and learning scientists.

There are papers and evaluations of outcomes on the OLI web site. One example is in statistics – in the first iteration the online students did as well as the students in the traditional course which itself had been worked on for ten years with cognitive scientists. Then they taught the course in a blended mode (meeting with faculty once a week, using OLI as the textbook) in half the time. Students (randomly selected) showed significantly greater gains than the traditional course. Now considering teaching all of the sections that way.

Courses are instrumented to provide instructors with lots of feedback. Faculty can be far more effective when they know what concepts the students are getting and where they’re having problems. The vision is to have a digital dashboard for faculty and students.

“Improvement in post-secondary education will require converting teaching from a ‘solo sport’ to a community-based research activity” – Herbert simon

Deborah Heyek-Franssen, from Colorado is talking about Carts & Horses in the Collaborative, Social Space. Technology is the cart, pedagogy and content should be the horses.

The basics – understand elements of learning, articulate content goals, find pedagogical method, and choose appropriate tool.

Some elements of learning -

Working memory – limited, seven “chunks” at a time. What does this mean for pedagogy? Chunking activity and keeping working memory available for learning. Can technology help? It can, but it can also harm it – e.g. slides with gratuitous images and animations. Cognitive load of looking at images or simulations is lower than reading about it.

Engagement – students get engaged in challenging, complex, multidisciplinary tasks involving sustained amounts of time. What does it mean for pedagogy? designing in and out of class activities that engage, including lecture and readings. Collaborative and social tools can help engage students.

Motivation – what motivates students? building motivation into course – rewards for desired activities.

Reflection – explaining and then critically evaluating own and others explanations. Wikis and blogs can help reflection.

Building on past knowledge – students now have opportunity to build global knowledge – e.g. wikipedia.

Deb notes that simulations can be addictive, and Greg comments that addiction doesn’t equate with learning. While that’s right, it seems to me that learning is at least more likely to occur if you’re highly engaged.

Shel notes that in research universities, even when faculty really want to teach, they’re mostly consumed with their research and even when we have tools and staff resources to help them, they’re not particularly interested in spending the time to work on really improving course methodologies. Joel notes that it works much better to engage with whole departments at curricular levels rather than individual faculty.

Cliff notes that collecting lots of real-time data on student activities has a creepy element about it and wonders about what the policy and privacy issues are. Joel says that there’s at CMU there’s an opt-in informed consent form they can assent to. And feedback is not granular at the level of individual students.

Greg says that the problem with assessment is whether or not people will make any changes based on the assessment, and if we don’t have institutions that make changes based on data then it may not be worth spending money on assessment.

Shel says they did a survey of large courses and 80% of students were using Facebook, but only 20% were using Sakai. So when they put the courseware into Facebook, the students didn’t use it there either.

Entourage sync with iCal – doesn’t work for me

So far my impression is that the Entourage 2008 sync with Apple’s iCal software doesn’t work. Well, sometimes it works. Sometimes it doesn’t. Sometimes events appear in Entourage but not in iCal. Sometimes the other way around. Sometimes they appear at different times in Entourage than in iCal. Sometimes they appear multiple times in both.

Hoo-boy. Color me depressed.

5,000 miles and counting

IMG_0029.JPG

Today on my way in to work I reached 5,000 total miles on my bicycle. That’s about the same as going from Seattle to Detroit and back (assuming one would want to go to Detroit in the first place).

It’s been almost exactly five years since I got my current bike, so that averages out to about a thousand miles a year. It’s definitely been more than that in the past year. While that doesn’t make me Lance Armstrong, or Kole Kantner for that matter, it sure feels good to be riding regularly, and I’m comfortable enough doing it in all kinds of weather that this year I gave up my parking pass (though I can always take the bus or use commuter parking tickets).

Reliable, human-powered transportation. What more could you ask for? I’m looking forward to passing the traffic jams on the first couple of days of Fall Quarter!

Javascript performance on browsers

Jim Gaynor reported these results of his runs of the Sunspider Javscript benchmarks on various browsers.

If you’re working in sites that make lots of use of Javascript (and who isn’t these days?), looks like the best performance on Windows by far is in Google’s new Chrome browser. The differences are much less pronounced among Mac browsers.

The Move (to Exchange) is on

Trying to get back to work after a great week of vacation in Bend, Oregon, and then surviving the first week of school for my son – now it’s time to get back to work! UW Technology Services, the unit I’m now part of, is in the midst of moving calendaring (and email) systems to a Microsoft Exchange environment. That’s a huge change, and one that has both positive and negative aspects. This will be the first of at least two and probably more posts on the topic – in this one I’ll talk about the background of moving to Exchange, and later I’ll talk about strategies for living with Exchange as a (mostly) Macintosh user.

Here in UW Technology we’ve used Oracle Calendar for our calendaring needs for a bunch of years, starting when it was known as Corporate Time, before Oracle acquired it. While it’s served our needs fairly well, there’s a growing feeling that the product family isn’t fitting into the technology environments we’re moving into – we’re not a big Oracle shop here, and the Collaboration Suite, as it’s currently known, is being tied to other pieces of the Oracle technology architecture. And it doesn’t help matters that Oracle Calendar’s client software, both in the desktop and web versions, is, well, clumsy at best.

We’ve also reached a point where we’re running a fairly sizable Exchange service for departments at the UW that live in a mostly Microsoft environment. That service is working well, and the units that use it seem very satisfied with it. For the large numbers of people who work with mostly Microsoft Office tools on their desktops (Word, Excel, Access), Outlook and Exchange fit right into their work habits. As units have moved to Exchange (or run other calendar systems) it’s become even more difficult to coordinate scheduling at the UW. To paraphrase the old saying, “A person with one calendar knows what meeting to go to, a person with two is never sure.”

We here in UW Technology have long been proponents of ongoing efforts to foster standards for allowing different online calendar products to interoperate for scheduling (we were the first charter member of the CalConnect consortium). It’s encouraging to see the progressive adoption of the CalDAV standards, which have now been implemented by Apple, Google, Mozilla, Zimbra (now owned by Yahoo!), and will be supported in the eternally forthcoming next version of Oracle Calendar, called Beehive. At a base level the CalDAV access protocol allows different calendar clients to interoperate with a given calendar server. The CalDAV Scheduling protocol allows clients to interact with each other independent of what server their calendars are stored in. Sounds promising, right? But you’ll notice one very large player missing from that list. Need a hint? Located in Redmond, initials MS. So despite all the forward progress, and Microsoft’s membership and participation in CalConnect, there still isn’t widespread calendar interoperability. Despite the lack of interoperability (or maybe partially because of it), Exchange now has by far the biggest market share among integrated groupware systems.

Exchange was designed in the early ’90s as Microsoft’s standalone groupware server, and they chose to implement the calendaring features by storing calendar data as specially formatted email messages that their Outlook client knows how to interpret. That means that in order to use Exchange for calendaring you also have to use it for email. I’ve been fairly vocal over the years in my opinion that this is a fundamentally flawed architecture – email and calendaring are different functions, and you ought to be able to separate them in the way they’re implemented and administered. I haven’t changed that opinion. But, for better or worse, architecture doesn’t always carry the day, and there are lots of features that are being added to Exchange (like unified messaging) that are things we know our institution will want to take advantage of. And it’s certainly not difficult to make decisions to implement Microsoft technology (though some of our peer institutions, like Indiana, report that running Exchange is considerably more expensive than running open source messaging systems).

So we’ve decided to bite the bullet and move to Exchange.

In some ways it’s ironic that we’re implementing Exchange at just the time when Macintoshes are becoming far more prevalent, iPhones are proliferating, and cloud-based email solutions are poised to be the next big thing. If I had to make a prediction, I’d guess that this current move to Exchange will last a few years after which we, along with most other institutions and businesses, will use email and calendar hosted by large vendors such as Google or Microsoft. But in the meantime, we’re off into a brave new world. In my next post on the topic, I’ll talk about the various current options (none of the really great) for Macintosh users in an Exchange environment, and some better options coming in the future.

Nice new mini from Dell

I think the Dell Inspiron Mini 9 looks pretty cool. A 9-inch screen, 2.28 lbs, built-in WiFi, and (unlike the MacBook Air), built-in ethernet and two USB ports. $349 gets you a version with Mini OS (Dell’s version of Ubuntu Linux), 512 MB memory, and a 4 GB solid-state drive. Upgrade to 1 GB of memory, a 16 GB SSD and add a webcam and Bluetooth and you’re still under $500. Sweet!
