The publishers of the well-known “Dummies” series of books have a website that includes both short written “how-to” reports and a few hundred videos, too.

The materials are probably not accessible to English Language Learners, so I wouldn’t place it on The Best Online Instructional Video Sites list.

A number of the videos might be useful to teachers trying to figure-out tech stuff, but I’d still say there are more complete collections on The Best Places To Learn Computer Basics & How To Fix Tech Problems list.

Nevertheless, it’s worth a look, and I assume it will only get better.
