The rest of us need to learn from the experience of those who go ahead first and move faster. The pioneers need assurance that others will extend the impact of their work, and that what the leaders learn won't be lost or wasted. This line of thinking should guide those of us who hope to improve teaching and learning with technology as well as those seeking other important changes. I should note, when I myself feel lazy I apply the same tests and usually move right along. Those who call others lazy stop far short of diagnosis in their description, and are usually projecting their own anger and frustration.
People do what they can do, and do their best to listen.
Often real change requires more or different activities at both a behavioral and affective level, as well as a different set of criteria in measuring impact, value, and speed. Until these activities are comfortable for everyone, some will always lag behind, regardless of how much commitment they may make to actually change their behavior. The label only makes it worse. There really are stages of adoption, and those stages really do describe processes which really do require a cumulative effect for any substantial change. And it takes many people a lot of time to change.
