I get that, it just strikes me as ridiculous that a curriculum about how to use the internet to learn would be summed up by: "Google, Wikipedia." Maybe the author is sacrificing too much depth here and I'm missing the overall point, but I'd rather teach my kids how not to use Google than teach them how to use it.
yes, this is a starting point. I agree this topic has considerable depth which I omitted.
there are 100s of great resources (Wolfram Alpha, Khan Academy, GitHub, Wiktionary, to name a few) and techniques (Google search tricks like using quotes, site: tag, etc., good habits like avoiding distractions) to augment Internet learning
you could evenly weight this area like any other class, and expect to spend many hours on it.
Hell, you have to teach kids about book features like captions and tables of contents and indices and footnotes and, believe it or not, kids aren't always great at picking up that knowledge even when taught.
