This morning I wrote a first post stating one of the reasons I believe learning semantically related items is of limited usefulness, at least early on in the learning process. There was a bit of interest in that post with the first part of my reasoning being called into question. But, it may be a couple of days before I can write the follow up post, and I didn’t want to let the discussion sit for that long.
So, I decided to put together a bibliographical post for those interested that would serve two purposes. One it will keep the issues in the first post alive perhaps until I can write a follow up. And second, it is needless to say that I lack credentials on this subject to a certain degree. My dissertation research has been in Applied Linguistics and Biblical Hebrew. As an interdisciplinary researcher, I run the risk of being an expert in neither area and knowing just enough about each to be dangerous. So, I thought I would refer readers to the studies by the credentialed applied linguists first. Then, I’ll weigh in with my two cents in a couple of days (I’ve placed myself under a bit of a personal deadline with regard to my fourth chapter of my thesis).
Against this background, the second reason I believe learning semantically related words together is of limited usefulness is based on research on interference. When dealing with the concept of interference one must at least deal with the idea that learning semantically related items together may actually be detrimental to learners. I believe that is what the studies below suggest. There is some research in the field of Psychology that suggests learning semantically related items together may be beneficial. However, this research primarily deals with the learning of lists of words in a subject’s native language, which is not the same as pairing form and meaning in vocabulary learning. These studies may even represent where the practice originated in vocabulary materials; however, the more recent studies focused specifically on vocabulary learning appear to call the practice into question.
I have arranged the bibliographical items by publication date and will almost certainly update the list tomorrow when I arrive in my office (or maybe after a staff meeting). I’m sure there is a pertinent article by Laufer I am forgetting as well as maybe 1-3 others.

Postscript – Here are also a Dissertation and MA thesis that may touch on this topic. I have not read them, but Laufer (see above) cites them:
Balhouq, S. (1976). The place of lexis in foreign language acquisition. University of Sheffield: Unpublished MA thesis. (According to Laufer, in this study learners of Arab learners of English had trouble with semantically related words dealing with family relations. This may have also had to do with cultural factors).
Stock, R. (1976). Some factors affecting the acquisition of foreign language lexicon in the classroom. University of Illinois: Unpublished PhD thesis. (Part of this study notes that learners have trouble confusing semantically related words like the two different colors of blue, i.e. kachol/tchelet).
