Okay, let's look at the "computer not recognising the iPod" problem, and see if by fixing that, we make sense of the other problem. However, I should note that the second generation shuffle really wasn't designed with audiobooks or podcasts in mind. If your audio lessons are stored on the computer as audiobook (media type) instead of music, they may not play. However I don't have a 2nd generation Shuffle to test this myself.
Now, I need to clarify a few things, because I'm not totally clear from the details you gave as to what steps you have tried, and what precise problem you are having. Just to be clear, the lesson audio files are stored on the iPod - is that right? Did you put them on via iTunes? If you just copied them across in Windows itself, in the same way that we put files on a USB drive, that won't work. For the Shuffle to recognise the files as playable media, you really have to sync them across using iTunes. That means that the program iTunes on your computer has to have the lesson audio files imported into it. Also, iPods are designed to only sync with one computer, so the files you want to hear on the iPod have to live on the computer hard drive to which you sync the iPod. Making sense so far, I hope? If this is all clear to you already, I apologise for telling you stuff you already know, but I want to make sure you're not making a mistake in the basic procedure of using iPods.
Lastly, when you say that the computer doesn't recognise your iPod, what exactly do you mean? Is there an error message that comes up when it is connected? If so, what is the text of the message? Or, do you mean that when you connect it, nothing at all happens, as if the computer doesn't even see the iPod? Giving a bit more detail will help the community to help you, if the above hasn't already solved your problem.
