Experience Publishing a Podcast
I found that the most challenging step was to host the physical media file on a web site. (edit) [I missed the moodle forum post where my prof directs us to use podbean] There were several suggested sites for hosting media files; some of them were free, others had a free trial, but none of the ones I tried was easy to use. I already had a Google Docs and SkyDrive account for hosting files in the cloud. Therefore, I attempted to serve a media file from Google Docs but the URL does not resolve to the actual media file, rather, the URL serves a page where the media file may be downloaded. …Ditto for SkyDrive. I needed a hosting service for a few other projects and decided to drop 4 dollars on a normal web hosting service that I could also use to host the media files. I registered a domain at Go Daddy and signed up for a simple web hosting service. Within about 15 minutes, my site was up and I was able to use their FTP tool to upload my media files. At this point, I had a live URL to the media files; I posted a Blogger blog post with a link containing the URL to my media file. Then, I provided my Blogger URL to my Google Feedburner service. Since this service is part of the Google single-sign-on landscape, getting started was painless. Feedburner provides a means to distribute content by subscription to a web portal, news reader, or podcast. The FeedBurner site provides a decent overview of feeds (http://www.google.com/support/feedburner/bin/answer.py?answer=79408&cbid=79408&src=cb&lev= index ).
I verified that my audio file was available through ITunes by clicking on the ITunes link on the Feedburner site. My ITunes application loaded and I was able to see my podcast audio entry in the podcasts section.

A learning situation I've encountered and the learning theories that applied
My experience with technologies mentioned in the learning objectives
My experience with flicker was useful. I generally use Google Picasa for managing my photos online. Uploading, managing, and tagging photos on Flicker was a straightforward. I uploaded a few images, tagged them, and organized them into a set.

Clifton and Mann, Can YouTube enhance student nurse learning?
I believe that this discussion should make a distinction between employing on-demand digital media over the internet and utilizing YouTube as a specific product/service. YouTube’s goals are generating advertising revenue and keeping their visitors on the YouTube site for as long as possible. The interface can be quite distracting if used in a learning context, especially for today’s students that are more easily distractible. Although YouTube can be employed as a teaching tool with varying levels of success, YouTube was not designed for this purpose. YouTube does enjoy a high level of adoption and a vast array of public content; you enjoy and utilize free content but you give up control and must submit to advertising. I believe that on-demand digital media on the internet can be incorporated into an interface that is specifically designed for that purpose.
Several psychological principals come into play with employing digital media for education. Clifton and Mann discuss surface learning vs. deep learning. One unintended consequence of a popular educational YouTube channel, Khan Academy, was that YouTube’s restrictions on the length of a video may have actually benefited the viewers. These videos are all about ten minutes in length and have been argued to be an ideal duration from a retention point-of-view. Although these videos have been popular, there have been challenges with schools that want access but have poor internet bandwidth. The YouTube model does not help. A new system was developed where the original videos were hosted on a local server in the school’s local area network and served from there. An educational media server platform should provide a flexible model that can accommodate these scenarios.

Fischer - Comparison of blogged and written reflections in two medicine clerkships
The Fischer article discusses the employment of new educational technologies. Fischer criticizes the use of new technologies without an initial comparison of their effectiveness with traditional technologies. This particular study found students performed about equally well in terms of level of reflection for the themes tested. A student’s preference between traditional writing and blogging for reflective exercises was found to be determined by the student’s prior experience. This study supports the idea that teachers may include blogging as a medium for reflective activities especially for students with prior experience. With the numerous learning and collaboration technologies that are becoming available, it is crucial for teachers to have metrics to compare a new technology with traditional ones. It is probable that employing technologies that are in the ‘peak of inflated expectations” stage may exacerbate the ill effects of using new technologies without due diligence.
