I must admit that I would be hard pressed to provide a reasonable definition of web 2.0. Perhaps the best way to explain is by way of example – the term applies to services such as ….
The Web 2.0 Awards site provides such a list examples broken down by category. You are provided the added benefit of learning which examples someone feels are the best of class.
USA Today has a recent piece outlining healthy habits that can help you stay sharp. The article concerns activties that may reduce the risk of dementia.
I would like my wife to review the list of suggestions. Doing Suduko puzzles is not on the list. Writing regularly in a journal is.
Blog on!
During the flight to my recent research conference, I was listening to a randomly selected educational podcast and encountered a description of NUVVO. I made a note to investigate this product when I returned home and had some time. Here is my comment.
I would describe Nuvvo as a CMS (course management system). At the low end, Nuvvo is a free service allowing anyone (a stated goal is to “bring out the teacher in all of us”) to build an online course and offer it to “learners.” The free version limits course authors to 25 MB of content. The free version also contains advertisements. If you wish to explore the capabilities of this service, there is a five minute screencast that explains core features.
I think this is a significant and interesting development. It is probably too early to speculate about broad topics such as what the opportunity to offer a free or inexpensive educational content management service might mean. Will ventures such as this challenge the place of traditional educational institutions in serving nondegree seeking students? Will such services challenges companies such as lynda.com or atomiclearning.com that provide specialized training? Will educators in K-12 settings use such products to extend classroom experiences?
Exposure to this service reminded me of the efforts of some of my University of North Dakota colleagues to develop a CMS product (HTMLeZ). University ventures have contributed much to the field of technology (e.g., the original Mosaic browser), but I wonder if such projects should be approached with a commercial focus. Sometimes a commercial opportunity emerges, but I think this cannot be the reason research and development projects are undertaken. Alternatives to the high end commercial products (e.g., Blackboard) are needed, but it is unclear how such alternatives will emerge. Will new ideas come from small commercial startups, from open source initiatives (e.g., Moodle), or from companies such as Nuvvo.
My local paper carried a wire service story on new problems with NCLB mandated testing. It appears that schools, with state encouragement, are knowingly not submitting test scores generated by 2 million minority students. The exclusions are based on a loophole that allow groups to be excluded when the group is not considered to be statistically significant.
When future teachers consider testing as an academic topic, they learn that tests serve many purposes. Included on such a list are evaluation and information. Problems can occur when attempting to use the same assessment to meet both purposes. The situation with high stakes testing reminds of comments Helen Barrett has made about electronic portfolios. She claims that when colleges use electronic portfolios to evaluate programs and students the value of the portfolio for self reflection is diminished. Students in such a system are reluctant to use the portfolio to explore strengths and weaknesses. The situation with standardized tests seems similar. Once consequences related to performance are in play, the interest in the information value of the tests become secondary.
I am having difficulty getting the comments feature of this blog software to work properly. If you have provided a comment, it is probably attached to the appropriate blog entry. However, the entry indicates that “No comments” exist. Selecting an individual entry will reveal the comment.
At this point, I am unable to determine why this is the case. I use a couple of plugins to protect against comment spam. The comments appear to be correctly identified in the database (valid comments and spam are labeled correctly), but the code that is supposed to determine whether comments are available is not function properly.
I want to fix this problem, because those who offer comments do so for the purpose of having their ideas distributed. If they simply wanted to get a message to me, they could send an email. Hey – if you are a WordPress user and have some clue regarding this problem, provide a comment! 🙂
Hey – I am making progress. I can now manually switch the “flag” that signals a comment. However, I should not have to do this manually. Comments provided in the past week or so are now visible.
One of the issues facing technology advocates is the increased focus on “scientifically based research.” Who can be opposed to good science? A presentation by Lynn Schrum and Kelly Glassett (paper online) provides a nice summary of this issue for the educational technologist. The paper argues for more complex (mixed model) approaches to topics that fall within this domain.
I apologize for my recent reduction in post frequency. I had intended to finish up the conference with a series of comments. I found myself spending a couple of days in the San Francisco airport trying to escape from the west coast. What are the odds two planes from two airlines would have equipment problems? My wife, flying to Mexico to complete a trip she intended to take a year ago during her bout with cancer, also was delayed because of mechanical problems. I guess I am glad these problems are found on the ground rather than once aloft.
I tend to follow the work of certain people so I scan the conference schedule to see if these individuals are giving a presentation. I noticed that Helen Barrett was presenting and we follow her work on the use of electronic portfolios. Dr. Barrett is presently working on the REFLECT initiative. She is attempting to determine how electronic portfolios can be used in high schools. The REFLECT site contains resources for those interested in electronic portfolios. REFLECT is supported by TaskStream.
We are also finding some time to take advantage of what is unique to San Francisco.
