Yep. I see a huge part of my job in the library as providing background knowledge about a variety of topics. We sing songs that I grew up knowing, and I talk about the history of the song and what one little phrase meant (for example, "My ship sailed from China with a cargo of tea" led to me showing them tea bags and loose tea leaves so they knew the ship wasn't carrying a load of brown hot water.) I point out which words in French have English cognates that are slightly different but related in meaning, like "marcher," which means to walk. And so on, and so forth, to build up that level of background knowledge that is absolutely crucial to long-term success. I got it through wide reading, and I encourage it that way, too, of course; but there are so many other sources of knowledge that most people don't realize they use.
