Reason and thought were most valued in this garden—all derived from the project of Enlightenment. Universities around the world were among the first to connect to this new medium, which hosted discussion groups, informative personal or group blogs, electronic magazines, and academic mailing lists and forums. It was an intellectual project, not about ...

 Teacher Approval Ends Discussion

He found this to be particularly true of positive feedback or praise. The rationale, of course, is that when a teacher communicates agreement with one student’s thinking, both the speaker and other classmates conclude that there is no need for further thought because the teacher has gotten the answer he or she was after.

 "This Is Not a..." Game

Older students continue and say, “This is not a toy telephone, it is a...,” and they gesture or mime to suggest the object that they are pretending the toy teleph...

 How Brains Respond to Positive/Negative Feedback in Child...

In children up to eight or nine years old, the dopamine-modulating reward center in the nucleus accumbens reacts strongly to positive feedback (activating the prefrontal cortex) and minimally to negative feedback. In older children, increased activation still occurs in the PFC when dopamine is released in response to positive feedback (particularly in response to correct answers/ predictions). However, the greatest age-related change is the higher reactivity of the NAc to negative feedback an...
