The Big6 is an information literacy framework. Any time a person needs information, they go through these stages. As adults, most of us automatically go through these stages whether buying a car, going on a trip or writing a lesson plan. For students, it is not as automatic which is why Mike Eisenberg and Bob Berkowitz came up with the Big6 back in 1998. The stages in the Big6 are: Task Definition, Information Seeking Strategies, Location and Access, Use of Information, Synthesis and Evaluation. The Big6 has stood the test of time and many have continued to apply the Big6 stages to the digital world as well. You can see how Doug Johnson and Mike Eisenberg created this document in 2001 that identifies how different technologies fit into the Big6 framework. Here it is in Pdf.
Several times a year, the Big6 publishes an enewsletter. The most recent newsletter is online now and includes an article about how Web 2.0 tools can be viewed in the Big6 framework by yours truly.
By the way, writing a blog entry is mostly a “synthesis” activity. However, as I think about how I compose blog entries, I have to start out with an idea which is “task definition.” And in creating the above hyperlinks, this is “location and access.”
