Research has found that, "when writing by hand, the movements involved leave a motor memory in the sensorimotor part of the brain, which helps us recognize letters. This implies a connection between reading and writing, and suggests that the sensorimotor system plays a role in the process of visual recognition during reading," associate professor Anne Mangen at the University of Stavanger's Reading Centre explains. And, "since writing by hand takes time, the temporal aspect may also influence the learning process." The University of Stavanger (2011, January 19). Better learning through handwriting.

So, The Sounds Of Words universal, explicit teaching, concrete, multi-sensory, reading decoding method is supported by this research, published in the periodical, Advances in Haptics. Hearing the sounds of the letters, repeating the sounds of the letters, WRITING the letters. MARKING the letters in the word to discover the "sound spelling", COPYING the "sound spelling", and then seeing the "sound spelling", the struggling learner is then able to read the "sound spelling", make the connection to the WRITTEN spelling, and then read and learn the word. Once the struggling learner learns the words, reading comprehension and fluency increase.
