Stanford Professor Bruce McCandliss found that beginning readers who focus on letter-sound relationships, or phonics, increase activity in the area of their brains best wired for reading.
Beginning readers who focus on letter-sound relationships, or phonics, instead of trying to learn whole words, increase activity in the area of their brains best wired for reading, according to new Stanford research investigating how the brain responds to different types of reading instruction.
In other words, to develop reading skills, teaching students to sound out “C-A-T” sparks more optimal brain circuitry than instructing them to memorize the word “cat.” And, the study found, these teaching-induced differences show up even on future encounters with the word.
