Revolutionary Battle Tactics
Here's one that illustrates well much that's right about online, sound-and-animation learning, and much that's wrong with industrialized education. There is sound here! Both a narrator and sound effects. Its simple: light enough bitwise that a dial-up user might well use it, and light enough content-wise that it won't overwhelm most students from go. And the graphics are simple but clear.
Then there's the bad part: the script is classic dry-as-dirt text-book-ese. Nothing to make you want to care about the subject, no rhetorical devices to peak your curiosity in event the mildest manner. Clauses of the sort that killed history education in schools in the first place. Active verbs? We don't need no stinkin' active verbs!
