(For week 14.)
I have been holding a bias that the content of podcast is always audios. A correct definition for a podcast can be "a digital media file (or series of files) that is distributed over the Internet." We have podcast, as well as vodcast which adds video to the podcast.
Audios add a different way to learn or layer of understanding for students. It's like the use of video, in line with the effect of dual coding theory. Cognition involves the activity of two distinct subsystems, verbal system and non-verbal system. Podcast extends learning beyond text to visual or aural memory, thereby fostering students dual coding of information (Paivio, 1986 from Lin, 2010).
Teachers can podcast to record lectures, summarize key points, show additional resources, etc. Students can use it to reflect their learning (as some of classmates have done), do projects, also show additional resources, etc.
In this respect, videos on YouTube can be called podcast. Blogs that contain videos or audios can also be called podcast. Podcast is a kind of broadcast. Then what's its difference from other resource sharing formats such as YouTube uploading and sharing activities in social networks? or is it a different dimension from them? I am slightly confused about this...
Suprisingly, I read from a survey in 2007 that 86.2% of the podcasters are males. Similiar phenomenon to contributions to Wiki. More than 90% pocasters have at least high school education. Similar to uploaders of YouTube. More than 80% are working full or half time and more than 60% are not single. Maybe work and love provide people with more experiences that worth sharing?
Podcast is not that money-consuming, but there's a conclusion that "North American podcasters tend to spend more money on podcasting than European podcasters". I'm just curious about how to spend money on podcasting...
Podcasters tend to target their audience to a small group and they interact well with their audience, via email or blogpage. Almost every podcast comes with a blogpage, but podcasters distinguish themselves from bloggers (How about classmates who do podcasting?^^).
People do podcasting mostly to share information or express their opinions.
In my eyes, podcasting is almost the same as blogging. The only difference is their formats of presenting information. One is in video or audio while the other is in texts.

Hi Shuya,
ReplyDeleteOne of the attributes of Podcast is extended the RSS, as it allows users to automatically download the programs or be informed the news message like blog article something like that AFTER subscribing.
As a matter of fact, perhaps seldom people care about that. Podcasting is famous and popular, because iTune University made a lot of efforts to combine hardware and software so as to provide access for learners around world to learning materials. And, those materials may refer to text, audio, video. Imagine that you just subscribe BBC podcast audio programs. Once you connect to the Internet, podcast programs will be automatically synchronized into your mobile devices via software. Thus, you are able to listen or watch it without Internet access to realize the ubiquitous learning.
