Reflective Wrap-up

The final entry on this blog is to be a reflective wrap-up.
I have really enjoyed having a blog to air my thoughts on various aspects of the materialin this course.  I wish that the blog was extending through the rest of the class!  And that there was more interaction with my fellow students within the blog.
I learned so much with this blog, in a kind of constructivist way.  I had a couple of themes and some simple, topical uploads. With my first post on "affordances", I began the "concept of the day" theme. In this first post, I extended on an idea brought up in one of the readings in Module 2b.  Writing about something, putting it into my own words and adding pictures, really helps me to make the material my own.  The other theme in this blog was "Tools."  In many ways tools are synonymous with technology.  The "Paen to the .pdf" post was meant to be humorous, but also to call attention to an overlooked tool that is not usually considered glamorous.

As a future instructional designer, I'd consider this blogging exercise to be one that really stretches the student, not only to use the technology of the blog, but to use it in a creative/constructivist way.

This article was in last week's Baltimore Sun. 

Wikipedian creds

The Chesney article, "An empirical examination of Wikipedia's credibility, " took on a subject I was curious about-- "how reliable is information that comes from Wikipedia?" and breaks it down into a scientific study with all the trimmings. To be honest, the value of the article for me was to see the details of the study itself- the controls, the variables.  The actual results of the study were not exactly compelling, in that there we not any surprises, and tended to re-inforce what I might have thought about Wikipedia- it's about 80% reliable.

Anderson and Dron cure the Newbie Blues


As a first-time participant in an asynchronous online course,  I got a better understanding of how my Technology in Distance Education & E-learning course is organized when I re-read  Terry Anderson and J. Dron's 2011 article, Three Generations of Distance Education Technology."  On my initial reading of the article, I focused on the first part-- a discussion of the evolution of Distance Education delivery technologies.  But the article's second half talks about theories of learning, and how they relate to the technology being used to present the course.

They explain that cognitive-behaviourist teaching models came about in the "pre-Web, one-to-one, and one-to-many modes; social–constructivism flourished in a Web 1.0, many-to-many technological context; and connectivism is at least partially a product of a networked, Web 2.0 world."

"CB [Cognitive-Behaviorist learning] models provide a strong structure to learning that
makes explicit the path to be taken to knowledge. When done well, a cognitivist or behaviourist approach helps the learner to take a guided path towards a specific goal," they say.
"Constructivist models still place an emphasis on scaffolding, albeit in a manner that is more conducive to meeting individual needs and contexts."  Connectivism, however, is kind of like being interested in a topic, gathering information about it and placing the results of your research on the web.  But, as Anderson and Dron so reassuringly state, "Learning in connectivist space is, paradoxically, plagued by a lack of connection."  This is reassuring because the lack of connection is exactly what I was feeling in this class.

The discussion of the connectivist learning model helped to show me that my reactions to the presentation of my class were possibly to be expected.   Anderson and Dron say that because: "Connectivist learning happens best in network contexts, as opposed to individual or group
contexts...the first task of connectivist education involves exposing students to networks and providing opportunities for them to gain a sense of self-efficacy in networked-based cognitive skills and the process of developing their own net presence." In other words, the overwhelmingness of the opportunities for learning presented in the course is intentional.  I am meant to begin by honing in on what knowledge I need and begin thinking about how to pursue it.  Talk about learning how to learn!

This also begins to explain why the faculty presence in this course seems so limited-- it might be part of the courses' approach to encourage students to develop relationships with other course members to get their questions answered.  As Anderson and Dron explain: "distance education interaction moves beyond individual consultations with faculty (CB pedagogy) and beyond the group interactions and constraints of the learning management systems associated with constructivist distance-education pedagogy. Cognitive presence is enriched by peripheral and emergent interactions on networks."

I like the way that this allows (forces!) students to take a good deal of responsibility for defining their own learning vector:
"In network contexts, members participate as they define real learning needs, filter these for relevance,
and contribute in order to hone their knowledge creation and retrieval skills. In the process, they develop networks of their own and increase their developing social capital (Davies, 2003; Phillips, 2002). "  I also like that in the connectivist approach, the products of the learning process (aka "artifacts") become part of an online dialog that can go on well after the class is over: blogs and wiki definitions, for example, as well as making student's research papers available to others.

Just to be clear, though, this illumination did not happen without pain.
For the first 2-3 weeks of this course, every time I would access the WebTycho learning management system, I would literally have a panic attack.   I experienced physical coldness, a sense of overwhelm, and the strong desire to give up.   It seemed like each task that I set out to do would lead to other tasks.   Not necessarily content-related tasks, but interface-related tasks.  There were tutorials to watch, passwords to get, the necessity to understand the rhythm of the course (while the course began on a Monday, modules were segmented to end on Thursdays).  All these feelings happened even though I was not under severe deadline pressure, and even though I consider myself to be technically savvy and comfortable with computers in general.  I think it reminded me of being in 7th grade at a "school without walls" back in the 1970's- I did not know where I was supposed to be or what I was supposed to be doing for any particular class.

Despite these challenges, I am happy to report that,  thanks to the availability and encouragement of the courses' writing coach, I cleared the hurdle of turning in my first writing assignment, and subsequently started to feel more in control of my learning environment.  There is more class to go, more assignments and more discussion board topics, but I feel that I have a better understanding of what is expected.

I understand that there is always going to be a learning curve when first attempting to do something new-- like navigate an online LMS and a "distributed" learning environment.  But I think it might be possible to provide more connection and encouragement for the student who is just beginning to undertake this kind of course work.  I'd be interested in researching ways to do that.

Looking At Tools #2: Paen to the Portable Document Format

Image Credit: Know Your Meme



Oh,  .pdf, I can't get enough of you. I think I am falling in love.

For so long, you were like some friend's little brother-- you were everywhere I went, kind of always there, but not very interesting, right?  I guess I thought you were just some kind of photo of a document.  But now, I  know you are so much more.

One of the first glimmers I had that you were special, .pdf, was when I realized that I could access you from my iPhone.  No need for Microsoft Word.  Just download you via iTunes, open you in "books", and there you are.  So full of information.

And I've known about your pseudo-legalistic functions-- that you can lock up information from a Word or a text document so that it cannot be edited or changed.  An archival sort of function.  I love that-  you are so stable.

But you are flexible, too.  With Acrobat Pro, you can be changed into a Word or a text document, and then I can edit your content.  The resulting document is a going to be new and different, not the original.  Not-- you.  This is what you mean to me--  the next time I get a lease from a tenant, it's YOU, .pdf, who will be my archival format.

Just lately I am realizing some of your other versatile and information rich qualities.
For instance, you can read yourself to me. This is my new fun thing, the new way to study.  Under the View menu, I put you on "Read Out Loud" and you read yourself.  You will read all the way to the end of the document, or read paragraph by paragraph, depending on what I tell you to do.  Clever, helpful, .pdf.

I realize that the fact that you are zoomable is pretty common these days.  Nearly every piece of text on the internet can be blown up to a larger size.  But you magnify so clearly, and so easily.  When I don't want eye strain, I just crank you up to 200%, and I don't have to squint or strain to make you out.
 You know that when I study, I zoom my you up to a comfortable visual level, turn on "Read Out Loud" and track you both visually and auditorily.  This helps me focus through the densest material... so sweet.  Your Hawking-like computer voice, reading your contents, has a lot of quirks of pronunciation and inflection, but really it is kind of cute.  I think that mentally correcting your reading-aloud quirks helps me stay focused.  And then at night, well, your monotonous tone lulls me in a way that rivals an audiobook by Deepak Chopkra.  Read me to sleep, .pdf.

I love the way I can highlight you, and make comments on you.  I can give your pictures tags and descriptions, search for a words and phrases in you, scan or screen grab stuff and turn it into you, and then back into a Word document that I can edit! You are magical, and have so much to give.  I want you with me always.  Hope my husband won't mind.

Concept of the Day: Affordance




Affordance -- finding tools everywhere



The idea of "affordance" has has come up in my readings for my History of Instructional Design class.  The term refers to opportunities for action provided by a particular object or environment. It is used in the fields of perceptual psychologycognitive psychologyenvironmental psychologyindustrial designhuman–computer interaction (HCI), interaction design and artificial intelligence, and in the focus of this blog, instructional design.

Jakob Johann von Uexküll (8 September 1864 - 25 July 1944) 
a Baltic German biologist
  
Jakob Uexküll with his son, Thure Uexküll 


In the 1920 article Kompositionslehre der NaturEstonian biosemiotician Jakob von Uexküll wrote of a "funktionale Tönung" or functional colouring inherent to objects.  While the pere Uexküll studied animals in their environments, the son, Thure Uexküll, applied this work into the medical field and cybernetics. (More)

The term, "affordances" was originally coined by American psychologist James J. Gibson as part of his work on optical flow.   His 1977 article "The Theory of Affordances" formed a basis for his 1979 book "An Ecological Approach to Design".  After his death in 1979, Gibson's wife, Dr. Eleanor J. Gibson, explained her theory of perceptual learning in An Ecological Approach to Perceptual Learning and Development.


James J. Gibson (1904-1979), U.S. psychologist and philosopher, first used the term "affordances." He taught at Smith College (1928–49) and Cornell University (1949–72).

 In his book  "The Design of Everyday Things." (DOET), Donald Norman adapts the term for the science of human–computer interaction (HCI).  Wikipedia explains:
"The original definition [of affordance] described all action possibilities that are physically possible. This was then refined to describe action possibilities of which an actor is aware. The term has further evolved for use in the context of HCI as indicating the easy discoverability of possible actions."



In this video link, Norman describes his take on "affordance."
