#PLENK2010 in #CCK11

February 27th, 2011

In this post I want to collect some links to personal learning issues and tools which I will probably also cover more fully in my PLENK site. (Week 6 of the cck course could be considered as a quick recap of the plenk one.) I expect it to grow over time as I will add things as they come to my attention.

Twitter is something that still doesn’t “grab” me even though many people swear by it. Perhaps this post at ZaidLearn will help me.


February 27th, 2011

Lindsay Jordan’s “paranoid thought” about cck11 does prompt a serious question about the ‘Groups vs Networks’ issue. How can the idea(l) of “flattening” the network’s connectivity function be promoted without needing a “spike” (ie a highly connected node like Stephen’s site) to do so?

Blogs – Declarative or Responsive?

February 25th, 2011

A comment by Scott Johnson on the CCK11FaceBook group refers to blogs as primarily declarative rather than responsive. Is that your experience? and either way are there things we could do to make them more conversational?

Learning Theories in CCK11

February 24th, 2011

I have posted in my main blog a plea for assistance in understanding in what sense “learning theories” are actually scientific theories with predictive capability.

My suspicion is that they might be better characterized as ideologies (ie as statements about what aspects of learning we consider important or valuable) but if this is wrong I would like to be corrected.

Groups vs Networks in CCK11

February 24th, 2011

This is a repost in order to get picked up by the cck11 gRSShopper system and start a discussion topic there.

I am puzzled by Stephen’s apparent preference for the “stability” of flatter mesh-style networks over the kind of rapid propagation of change (“cascade” phenomena) that is facilitated by a power law distribution of connectivity.

I am tempted to ask why cascades of new ideas are not to be encouraged and where the line should be drawn between “stability” and “stagnation”. Any comments here (or links to discussions elsewhere) to help with these issues would be welcome.

Another Test

February 24th, 2011

This one has the tag just attached via WordPress and not in the title or body.

Not Expected to Show Up

February 24th, 2011

This is just a test to confirm that, with category only and no tag or content reference, it will not get picked up.

Missing Posts

February 24th, 2011

A couple of my earlier posts (this and this) didn’t get picked up – perhaps because I used the cck11 tag only as a category (and in the blog url) rather than in the content or title of the post.

(And adding it retroactively didn’t seem to work either)

Distributing the Dialogues

February 22nd, 2011

In the discussion thread Dialogues (help!) there has been some mention of the tendency of the cck11 network to concentrate itself in the gRSShopper site and perhaps also on Facebook. In the interest of encouraging a more distributed network, I suggest that when a discussion has been started by commenting on the gRSShopper listing of a blog post (is there any other way?) subsequent contributions to the discussion be made as comments on the original post rather than on the gRSShopper site.
