The Case For Direct Instruction

I have a personal interest in the benefits of student multimedia authoring (e.g., web design, blogging, video production). The idea is that students author products associated with their content area study and I assume they benefit from such activity. To me, this idea is not a huge leap of faith. Educators have been promoting and researchers have been evaluating writing to learn and writing across the curriculum for years. Large scale multimedia projects might be viewed as an alternative to a term paper. Smaller scale projects are more the equivalent of other less utilized writing to learn tasks.

Our interest in student authoring is not unique – many interested in K-12 technology applications have encouraged multimedia projects. Often, this approach has been identified as constructivist. The difficulty I have with this label is that it appears to mean different things to different people. When I think of a learning theory, I assume the theory is an effort to describe how learning happens. To me, the idea that a theory is about a technique is misguided. It seems possible that different technqiues might result in better or poorer learning, but inappropriate to label some technigues as constructivist and some not. So I see theories as constructivist (i.e., learning requires the integration of what is known with new experiences) or not, but not experiences. My professional training involved a focus on information processing theory – I understand info processing theory as an attempt to explain some of the details of constructivism (which to me lacks attention to the specifics of learning).

Anyway, my wife sent me a reference to a blog entry summarizing an Educational Psychologist article (Kirschner, Sweller, Clark – 2006) critical of constructivism, discovery learning, experiential learning, etc. A draft of the Kirschner, et al. article can be found using a link from the blog (the journal publication date listed on the draft is incorrect and should be 41(2) – I suppose the journal got a little behind). The article argues that learners inexperienced in an area of study do poorly when allowed too much freedom in their approach to learning (hence the references to some of the very early critics of discovery learniong – e.g., Ausubel). Perhaps recognition of this reality is why some constructivists are careful to recognize the need for scaffolding. This is a good analysis and understanding such issues is important.Some of these topics remind me of political controversies – i.e., your approach is boring and meaningless, students can’t learn about topics for which they have no background.Comments on the Kirschner, et al paper seem to be rippling through the educational blogs. The day after the original version of this post the Connectivism blog commented on the same article. If the distinction between constructionism and constructivism is of interest to you the connectivism post has much more detail (too many isms for me to explain).

What I like about Kirschner’s approach is the connection (pardon my use of this term) with the empirical literature. Those taking a contrasting position seems to rely on philosophy, anecdote, and personal reflection. The Kirschner article, Mayer’s Ed Psychologist article, and a historical series of similar complaints (e.g., Ausubel) seem to beg for engagement in a “scientific” debate. If no data exists to counter their concerns, perhaps the first step would be admit this problem and then at least outline the types of demonstrations and the data types that could be used to argue for a different position.

Blogging NECC

NECC (National Educational Computing Conference) is coming up in a little over a week. NECC was the occasion of my initial blog posts (back in 2002) and I have posted from NECC since. For me, it is possibly the best conference for learning about K-12 technology innovation. NECC has since organized bloggers. I don’t participate in the organized venture – too much pressure to generate a body of focused content for me.

David Warlick proposes that those who attend and blog tag their blogs NECC06. This practice will provide some evidence of the impact of the conference (check Technorati) and also allow interested parties to locate NECC related posts. A good idea I think.

Politics of the Internet

An ad sponsoring the local news this evening asked television viewers to act in opposition to the Snowe-Dorgan ā€œInternet Freedom Preservationā€ bill (Net Neutrality). The ad included a web address (http://www.handsoff.org/). Senator Dorgan is from ND, but this ad may be airing everywhere.

My previous post in support of the concept of net neutrality focused on an issue that the “hands off” site describes as “access tiering” – a practice in which network owners charge more for certain services or control the speed of a category of informtion packets.

I understand the issue of access tiering, but I am attempting to understand the competing position. Is it that the providers are claiming they need new revenue opportunities to encourage development of an enhanced net? What is unclear to me is whether new revenue opportunities would imply that existing user opportunities would go away? For example, would a VOIP channel without “break ups” be added if “free” Skype audio communication can be degraded or would a VOIP channel be available for a fee and Skype would continue be available for those willing to tolerate the service as is?

Commercialization and Critical Mass

Imbee, a new “safe” social networking and blogging for 8-14 year olds, has just been announced. There is a cost for full service and I wonder how this will influence participation (there are free alternatives – e.g., blogmeister).

I would guess the success of such ventures depends on some type of “critical mass.”

  • Will your average 7th grader be interested if his/her friends don’t have the $30 per year to join?
  • How important is the “unknown audience” to bloggers? Perhaps knowing that the audience is restricted will reduce motivation to be an active participant.

I see that additional individuals can be added at a much reduced rate. Perhaps there is some way to enroll a class of paricipants if the class can raise the money.

I think critical mass is a crucial concept in the popularity of social networking. The challenge is how to achieve what adolescents accept as critical mass within a restricted environment. I do think it is great that investors are willing to offer some alternatives. The services likely warrant the price. Good luck.

Google Spreadsheet

I encountered an announcement for the beta Google Spreadsheet program and signed up. I received an invitation to try out the service and so far I have been impressed.

I did try to load a large dataset (64000 or rows of data) without luck. I did not read the instructions and this may exceed the limit allowed. I was able to upload and add to a 200 row dataset. Free and shareable – pretty cool.

Blogs Are Not Enough

I like reading blogs, but I am reaching the conclusion that blogs provide an incomplete and possibly distorted view of the world. To make well reasoned personal decisions, one has to gather and consider multiple perspectives and my concern is that in some areas blogs may not provide such opportunities.

I am personally very interested in student multimedia authoring. Part of what I know about this topic I have learned over the years by reading academic research (e.g., David Jonassen, Richard Mayer, Richard Lehrer). Part of what I know more recently, I have learned by following several blogs. Because I also read critics of this area, I still struggle with what I am willing to claim with certainty about this topic. When it comes to accepting a role in which one advocates, I think some healthy uncertainty is a good thing.

Here is what I have noticed about educational blogs. Influential researchers appear not to blog (try searching for the names I mention above) and influential bloggers tend not to publish research (try using Google Scholar to search for the name of someone you consider an influential blogger).

You may disagree with this statement and there are probably some exceptions, but I do think this statement generally holds and wonder why this is the case. Perhaps it is a matter of how people spend their time. There is not a great deal of recognition accorded university scholars for time spent blogging. Popular bloggers may not work in circumstances in which research is expected or possible. However, I am also concerned that research and blogging require different “styles”. When I began writing textbooks, the editors spent a great deal of time moving me away from a careful, conservative writing style. Simple and positive was good. Careful and nuanced was bad.

This is not a comment in which I am seeking to blame anyone for anything with the possible exception of those who think they have adequately informed themselves because they read the comments of popular bloggers.

A concluding contradictory example: I do think it is possible to completely ignore a commonly accessed information source. I “know” this because my wife is a fan of conservative talk radio. When I ride in “her car” this is the channel she has on the radio. Cindy has far from conservative views on most issues. I have tried to reconcile Cindy’s attitudes with what I have observed about her listening habits. Here is my conclusion. Some people who spend a great deal of time by themselves in a car sing along with the radio. I think Cindy likes to spend her time alone yelling at the talk show hosts she thinks are idiots.
