There are so many times I hear these words: "But, I'm more of a visual learner." In many ways I think all of us are visual learners. If there is just something we don't get, and we see it, then it finally clicks. I just came across this tool in my Google Reader, Wordia. This is a new tool that I think will really help younger students with vocabulary. It is pretty much just a big visual dictionary that has the meaning, definition, and a video to go along with the word.
One draw back about it is that it looks fairly new, so there might not be a video for every search you try.
