Bias in assessment

Every form of assessment of learning has bias. This bias may be hidden, or it may be quite obvious. As Cathy O'Neil points out, assessment is a proxy for what we want to measure - learning. We cannot measure the building of connections between neurons that is happening in the brain directly (or even potentially understand what that growth even means) so we use a proxy in the form of an assessment of the externally visible signs of learning.

Access to computers

President Obama recently unveiled a plan to have broadband Internet access in every school across the United States by 2018.

I'm working on a presentation on creating presentations.

Host your own services

When you rely on a service, particularly a "free" (ad-supported services aren't really free) service, you always run the risk that whomever is maintaining and controlling the service will shut it down, or strip it of functionality so as to make it less useful (or even useless) for you. This happened to Google Reader, it almost happened to Delicious, it happened to Posterous; this list will continue to grow over time.
