It is very common for individuals to socialize with other people to form new knowledge in order to solve problems. A group of people who share knowledge and practices on an ongoing basis to deepen their expertise form a community of practice (COP) (Wenger, 1998).
Knowledge is created when individuals interact inside a COP. Nonaka and Konno (1998) suggests that codification of tacit knowledge is important to share knowledge. Conversation that happens within community of practice brings a lot of potential to create new knowledge. Codfying and sharing the conversation can bring a lot of benefit in sharing knowledge.
There are plenty of way to codify the tacit knowledge from the participant of a COP. The simplest way is to transcribe the discussion using traditional pen paper, or creating an electronic file to store the discussion into an computer enabled information system.
What is a podcast ?
I would suggest we should create a podcast from the discussion.A podcast is a series of digital media files that can be downloaded through the internet. Method of delivery includes streaming the media through the internet. Another alternative is to use a software to periodically download the media files from the internet and watch it over their laptop or mobile devices such as smart phones.
Benefit of a Podcast
A study conducted in a university (Nie et al, 2008) shows that podcasting create a lot of cognitive benefit. Some of those benefits are:
a. Podcasting foster collaborative learning by allowing the listener to view information from a different perspective.
b. Podcasting motivates both listener and podcast in the learning process. Podcasting motivates the producer to produce a creative podcast that is more engaging to the listeners compare to traditional media such as written report or web page.
c.Podcasting enhances the listener understanding of the material by allowing them to pause and play back the video or audio file.
A study in London by Evans, C. (2007) show that podcast allow student to study. Many of them listen to podcast while they are traveling. Podcasting has the potentially to fill a gap by allowing learners to continue the learning activities when it might not normally be possible
Transcribing a podcast
Browsing a full recording of a podcast can be consuming. M Goto, J Ogata, K Eto , (2007) has done some research on intelligent sofware that can automatically transcribe podcast. Their project is called Podcastle. Their project promises a lot of potential to create a software that we can use to mine information and data from a podcast. Transcribing a podcast allow us to extract and browse information from a podcast faster.
