Many of you are familiar with Rogers' diffusion of innovation theory, even if you didn't know its formal name. Dr. Everett Rogers is probably most famous for popularizing the following diagram:
Rogers Diffusion of Innovation Bell Curve

We often think of this bell curve when we initiate new technology initiatives: Who are the innovators that will jump at this first? When do we start involving folks other than the early adopters? How do we get the rest of the folks (i.e., the late majority and the laggards) on board? And so on...

But Rogers also talked about how the adoption of any innovation (i.e., change) tends to occur in five stages:

  1. awareness,
  2. interest,
  3. evaluation,
  4. trial, and
  5. adoption.

And, importantly, he also discussed what he called perceived characteristics of innovations. These are things considered by potential adopters that affect how likely those potential adopters are to move from awareness to adoption. They are:

  • relative advantage (the 'degree to which an innovation is perceived as being better than the idea it supersedes');
  • compatibility ('the degree to which an innovation is perceived to be consistent with the existing values, past experiences and needs of potential adopters');
  • complexity ('the degree to which an innovation is perceived as difficult to use');
  • trialability ('the opportunity to experiment with the innovation on a limited basis'); and
  • observability ('the degree to which the results of an innovation are visible to others').

Innovations that have greater relative advantage, compatibility, trialability, and observability, along with less complexity, generally will be adopted over innovations that do not.

Numerous school technology initiatives fail to result in widespread changes in educator practice. One prevalent reason is because they did not adequately address the very rational concerns that educators have about one or more of these perceived characteristics of innovations. Anyone who is trying to make wide-scale change happen in their school system must address these sufficiently to alleviate the concerns of the late majority and laggards. Otherwise only the innovators and the early adopters will jump on board, along with some, but not all, of the early majority. I'm sure all of you can think of instances of this and hope you will share some in the comments area.
