First, ask yourself how you learn most efficiently.
People learn in different ways.
Some are more visually inclined than others and learn by watching. And some of us actually sit down with a computer and hack our way through new technology. AppDev's XML Professional Training via CD-ROM attempts to cover all these methods in one multimedia package. Composed of video segments, PowerPoint-type slides, and screen captures of example code, the CDs present more than 10 hours of instruction. The instructor for this particular offering is Martin Schaeferle, AppDev's IT Director and a speaker at Microsoft's TechEd conference.
