Snowball sampling is a special nonprobability method used when the desired sample characteristic is rare. It may be extremely difficult or cost prohibitive to locate respondents in these situations. Snowball sampling relies on referrals from initial subjects to generate additional subjects. While this technique can dramatically lower search costs, it comes at the expense of introducing bias because the technique itself reduces the likelihood that the sample will represent a good cross section from the population.

    Here’s a thought – what about using blogrolls to identify other classroom blogs? That said, I think that would work for classroom teacher blogs but not classroom blogs. I’m guessing classroom blogs might use their blogroll to connect to relevant (math, etc.) resources?

    However, what if we do ask each teacher blogger to recommend 1-3 other classroom blogs?

    I believe that although there is the opportunity for bias, this is in some ways the nature of connecting into the blogosphere and social networks. Thus, our method for sampling mirrors the ‘friend of a friend’ concept that is so prevalent in web 2.0 technologies.
    We are thus following the discourse as it is being situated in the different academic social constructed networks and positioning that is occurring through the selection of specific references and resources.
    It seems a method that actual is appropriate for this type of topic.

    Ok…we are posting at the same time and so I missed your comment.
    I think this is a great idea (about using blogrolls to connect)… I wondered the same thing when looking at some classroom blogs tonight. See the list at of possible classroom blogs. A few of them are not great in themselves but have an extensive blogroll.
