Yeah, Rosen probably doesn't even remember that that was how he was taught to read. Generations of children were taught to read by phonics. How did Victorian school children learn? From primers that taught them the different spelling patterns. Phonics teaching simply tells children them how different letters, in different combinations, represent the different sounds of speech.
Honestly, nothing annoys me more people like this mooning on about how teaching children properly takes away all the pleasure of reading. No, in fact it gives them the pleasure of reading because THEY CAN DO IT!
Any children who learn well by the whole word approach still learn this way while being taught a phonics approach - they pick up whole words by sight quickly as well as learning rules to decode unfamiliar words.
