Technology and environments...

Can teachers be affected by a technology culture created by leaders and other teachers?

Simply put, yes; though there may be a difference of degree.

If a leader has *authority* and creates a culture which requires participation by teachers, then how this environment affects teachers is clear. For example, if a principal lobbies for a change to allow students who are ill to attend classes virtually, then every teacher in that school will be affected by the addition of a new, required technology into their classroom (and environment). 

If a technology culture is created by other teachers who lack authority to mandate its adoption, then the certainty of effect is less clear. Suppose a group of teachers form a group to experiment with using Google Docs in the classroom for assignments and collaboration. Assuming joining the group is voluntary, then teachers who do not wish to use Google Docs won't be immediately affected. However, as time progresses, let's suppose that the original group regularly reports back to the larger faculty group how well it's going. The group has identified X number of issues or problems and has developed practices to minimize them. The students are able to collaborate much more easily. Teachers are able to see who has actually contributed (through Google revision history). And teachers are able to easily comment on assignments and allow students to comment back to help have more lengthy conversations about particular issues. After this point, some of the teachers who weren't participating, my find that they now believe that the benefits outweigh the negatives. Now they are ready to move forward with Google Docs. Or, they don't. :)
