I think flash cards, LR, and Doman-style ppt presentations are better at teaching word-picture associations than these sorts of books. But with my little boy, we’ve used just the sort of early vocabulary-building book you found (there are zillions of them) a lot since he was a baby, and no Doman stuff. I’m very sure that going through books taught him a lot. But I think the ppt presentations and other presentations we’ve looked at since he was 22 months old or so were possibly more efficient. Doman was really onto something when he emphasized the size of the text and the clarity of the picture, and showing one word/concept at a time. He definitely got that right, as far as I am concerned.
By the way, as your baby gets older, consider checking out the many Richard Scarry books like What Do People Do All Day, which teach concepts in a fun way. The type is small, but these books entertainingly introduce loads and loads of concepts. My own little guy loves these. He also loves The Oxford Picture Dictionary, which is actually aimed at ESL learners. There are many other picture dictionaries and picture encyclopedias aimed at kids, but my boy likes OPD best, for whatever reason. Your (tot’s) mileage may vary. I’d be curious if anyone else has had good luck with OPD–it’s a real phenomenon with our little boy, we’ve been reading through this book for well over a year, from cover to cover, a page or two at a time. He still hasn’t gotten tired of it.
By the way, though, I think a child can learn more language more efficiently by being read to a few hours a day from a very early age. The Doman “word-picture” flash card method cements word-concept associations and can teach a child to read, which are wonderful things. But what they don’t do is teach a very wide and rich vocabulary and many different grammatical structures–in fact, nothing comes close to good old-fashioned books (or digital media that imitate books, like my own ppt presentations!) in teaching those things.
We didn’t discover Doman or Titzer until he was 20-22 months or so, and while we did some commercial flashcard stuff when he was a baby, it was mostly books. He read his first words at 22 months. He’s now 3 years 7 months and is sounding out words at the fifth or sixth grade level. He has a phenomenal vocabulary and uses–often correctly–some very advanced grammatical structures, like subjunctive mood. (“If I were to pull this ornament off the tree, would it break on the floor?”) He puts together Lego sets marketed for ages 5-8, with only a little help from me. The point…other than giving me a chance to brag…is that there are many ways to do intensive early education. We used mostly lots and lots of books, and only a few videos, and not so many flashcards or powerpoint presentations/LR stuff, before the age of 22 months or so. But I’ll tell you though, once we started those flash cards and later my ppt presentations, he blossomed as never before. So I am a big Doman fan, despite my reservations about some of his hype…
Hope this helps. I’d be participating more here, but work has kept me very very busy lately.
