I have entered into a discussion of Biblical Hebrew vocabulary learning that has been taking place on a couple of blogs. You can see my post here and the posts where the discussion kind of took off here and here.
Biblical Hebrew vocabulary learning has been the topic of my dissertation research, which I hope to defend successfully a little less than two weeks from now. There seem to be a couple of schools of thought developing around where Biblical Hebrew instruction needs to go. Anyway, hopefully beginning to talk about this a bit more in the biblioblogosphere could lead to some helpful developments.
By the way, Joel, I know that you are very interested in this topic and happy to see me posting about Hebrew here on your blog.
