A propos of the “Fourth Grade Slump,” it can occur for several, quite different, reasons. Kids who have learned to read with solid synthetic phonics can still experience difficulty when they have to decode multisyllable words.... Even in the famous Clackmannanshire study (pdf file) (where all the students were taught a systematic phonics approach similar to Jolly Phonics), a number of students had to be specifically taught how to read multisyllable words in Year Four. They developed a program called “Phonics Revisted” to deal with this. It included, IIRC, learning to segment multisyllable words, some morphemic strategies, and emphasis on less common correspondences. Unfortunately the Clackmannanshire report doesn't provide many details.and see:
However, the Clackmannanshire study only replicates what has been found on this side of the pond as well. Many students who are good decoders, because they have learned (or intuited) basic phonics skills, come to a screeching halt at mutisyllable words especially, as in examples by Allison and Chemprof, scientific terminology. These skills can be systematically taught, of course.
