Digital Scrapbook --A class project

Social networking/media
Blog, twitter, texting are typical social network media. Perhaps texting is the most universally used, with about 1 trillion text messages sent in the U.S. alone in 2009. http://www.textmessageblog.mobi/2009/02/19/text-message-statistics-usa/.
Twitters and blogs are close behind, with twitters perhaps covering a wider population. Blogs are common with specific communities--academic, travels, equipment repair,...

I opened a blog to follow developments in the physical and environmental sciences, primarily.
I can be followed at http://obidity.blogspot.com/

These devices tremendously reduce the delivery time of vital information and learning skills because (i) they reduce search time, (ii) they reduce note-taking time, and because of the massive storage capabilities that they have (iii) they provide many examples of concepts covered. Here's a blog I found for Physics and physics related discussion:
It's not just about the science of Physics. It discusses the cost of some physics tests, the problems with some testing methods, etc. Such holistic approach to science gives more value to the subject by reaching a broader community, and by encouraging scientist to think additionally of management and socioeconomics.

Here are some of the topics covered:

High Cost For Underground Physics Experiments


Doing Experiments In High Schools Not As Effective As Thought?

A tool for asynchronous communication
Blackboard and MOODLE  are tools for asynchronous communication that I am familiar with.
The MVCR classes use MOODLE www.moodle.com  and the Chicago City College System  uses Blackboard
http://www.blackboard.com/

Here's an example of a thread that I started on a discussion topic using MOODLE

#4 Often, faculty members deliberately decide not to participate in discussion in order to promote dialogue between class members. How successful do you think this policy would be and why? Under what conditions would you NOT participate?



I tend to think that such a policy would not get the best out of students. There is a much greater tendency for students to ‘chip in’ when the instructor makes a comment in a discussion forum than when the students are all on their own. There is also a more serious discussion when the instructor participates.

All that is required is an occasional comment that helps to provoke further thoughts on the topic being discussed. The instructor does not even need to express an opinion—just throw in a couple of comments every now and then to steer the discussion aright and to generate further quality contribution from the students.

The instructor would probably not participate if, as part of the discussion, students are required to do individual web search and to list / submit / discuss the findings for credit. Such specific instances are uncommon, though.
They are both good teaching tools for text  delivery but could be improved with the inclusion of a participant's 'avatar'. We like to look at the person we're talking (or listening) to. We would, at least like to be able to see the picture.
A tool for synchronous communication
Elluminate is gaining ground as an industry-wide tool for synchronous communication www.elluminate.com. It is particularly useful as a teaching tool, incorporating graphic features for the presenter. It also mimics 'hands up' (to ask questions), and allows audio interaction with the presenter. Cell phone is probably the most available synchronous teaching tool but it may have limitations such as the inability of a cell phone type to display graphic features. Also, texting is not an automatic feature with cell phone service. Here's how I responded to a question in this regard:
Question:If you have a phone with texting capabilities, we encourage you to select option A. If you do not, options B or C are for you.
A poll has been created using a free tool called polleverywhere.com. The question is "Would you consider the integration of cell phone technologies into your teaching?" There are three ways you can respond.
My answer:
I chose "Thinking about it, Maybe.' My gut feeling was to choose 'Absolutely not!' but I feared  (a littlebig grin) that I might be perceived as reactionary, and a hardliner at that.
First, the cost of cell phone service /subscription has not come down enough to expect that everyone has an active cell phone all the time.
Second, there are still people who have phones but have no texting option --texting is not part of the basic package (it's still optional at cost).
Third, if the cell phone is misplaced (which happens often), the student will not receive the message.
Twitter or wiki is preferred. An access to the internet anywhere--library, airport, Hawaii, Zanzibar--is all that'sneeded.
I might consider texting for polling. The only trouble is, the polster does not absorb the (text/phone) cost of the customer response. If I respond to a poll, I'm doing the polster a favor (--well, at least a service). The least that I can expect is for the polster to absorb the phone cost of my response (even if it's a penny).

And, yes, it's an asynchronous tool. Sometimes though, it almost seems like a synchronous tool coming from my children or any of these little kids. They seem to respond to the text at the same time that they're getting my text. It takes me eternity to respond to them.
Moodle chat is also a synchronous tool. It's particularly good that the recording can be played later either for further analysis or by someone who may have missed the chat. The only disadvantage that an absentee suffers is the inability to contribute to the live event. Stuff happens such that even when we're all set for a live chat, we can still miss it. Here's my recent expereience
I was scheduled for a Moodle chat at 9:30 p.m. on Thursday. I went and got a brad new headphone with mike on Wednesday, excited and ready. I got ready an hour early, or so I thought. I could not login to mvcr. I though I was tech savvy so I started various troubleshoots (--in retrospect, I think I was just hacking around). By 9:00 p.m. I started sending fyi text messages to Norm. 9:15! I sent out several SOSs to Norm, to Scott Johnson, to the Help Desk, and one to a prayer line.
I shut down the computer, walked away in frustration. When I came back, I got on (around 10 p.m.) and started my moodle--all by myself. After playing the dual roles of the  initiator and the responder for a few minutes I signed out with 'O well.'

btw. Norm sent me a 'reminder': FYI, Moodle chat is strictly text. There is no audio involved, so headphone and mic aren't needed. They do, however, work if you are using Elluminate or Skype.

There are about 4 videos in this article,
They are brief but succint. They are what I usually refer to as the physics of the problem.
There's no intention to bore you with the text. Just click on any of the linked videos. 

Here's an interesting and timely podcast: http://www.physics.org/explorelink.asp?id=5101

This is a Science Johns Hopkins University School of Medicine researcher addresses the question Can It Be Bad to Be Too Clean?: The Hygiene Hypothesis
A content that I produced   
Here's a podcast that I made on Creating White Light
http://obidity.podbean.com

A podcast is easier for some students to follow than the voluminous text opn the same topic. One can listen to a podcast in the posture one finds most comfortable--no need to belabor the ischium (or the eyes, for that matter) for hours.

Produced in the 7th week (survey or teach-back)
I made a math quiz for an introductory physics class. The outcome of the quiz determines the extent of review that I may need to give the class. This quiz was made using proprofs. It can be accessed at

An elective .... something new I'd like to try 
Gesture-based computing sounds cool. I'd really like to try it. It's a take-off from pattern recognition technology.
2010 Horizon Report presents some learning opportunitites in gesture-based learning and Structural Augmented Reality (SAR).

23 Things post
Here's my list of 23 things that online teachers may consider as guidelines in the effort to be a continuously better teacher in general, and online teacher in particular.
