interesting idea... what if a teacher maintained a diigo group so that s/he could bookmark sites s/he wanted her class to look at. This example is of a parent making a blog to aggregate content.
A primary obligation of 21st century teachers is to open the doors to 24/7 learning, helping students understand that they can access education from virtually anywhere, at any time.
Their backers also say that teachers’ freedom of speech is imperiled when we penalize their out-of-school remarks.
But these defenders have it backward. The truly scary restrictions on teacher speech lie inside the schoolhouse walls, not beyond them.
