A great article about appropriate modelling by adults from Marti Weston on the Teaching Tolerance Website, which is part of the Southern Poverty Law Centre, an online resource focused on; 

"reducing prejudice, improving intergroup relations and supporting equitable school experiences for our nation's children"

The focus for the article is how important "non technology" teachers roles are as models of appropriate behaviours.

"these students yearned to view their instructors as technology behavior models, just as teachers serve as their models in other ways"

The article talks about this idea from the perspective of classroom experience, where the inspiration, the process and the outcomes are highlighted.

Its well written, well balanced, and the ideas are simple to institute.
