Spelling Difficulties and the Learning Disabled
Students with learning disabilities in reading usually have problems in spelling as well, and oftentimes have more severe deficits in spelling than in reading, according to Hallahan et al. in Introduction to Learning Disabilities. In reading, context and other cues help one to decode a word, but in spelling, one must produce the word after hearing or thinking it. As a consequence of their difficulties with spelling, learning-disabled students find writing tasks both laborious and aversive.
Spelling requires that a person produce in written or oral form the correct sequence of letters that form a particular word. To do this, a person converts phonemes (sounds) into graphemes (written letters). There is only one correct way to spell any particular word with a given meaning. Thus, spelling does not allow any room for "creative" answers or "style"; a word is either spelled correctly or it is misspelled.
English is difficult to learn to spell. It would be much easier if each phoneme had one and only one grapheme. But that is not the case. There are 251 different spellings for the 44 sounds of English and the language contains many irregularly spelled words.
What Causes Spelling Difficulties?
Successful intervention is dependent on finding the cause or causes of a problem. A disease such as scurvy claimed the lives of thousands of seamen during their long sea voyages. The disease was cured fairly quickly once the cause was discovered, viz. a vitamin C deficiency. A viable point of departure in this case would thus be to ask the question, "What causes spelling difficulties?"
To understand the cause of spelling difficulties it is important to take note of the fact that learning is a stratified process. One has to learn to count before it becomes possible to learn to add and subtract. Suppose one tried to teach a child, who had not learned to count yet, to add and subtract. This would be quite impossible and no amount of effort would ever succeed in teaching the child these skills. In the same way, there are also certain skills and knowledge that a child must have acquired first, before it becomes possible for him to benefit from a course in spelling.
The skill of spelling embraces many subskills. Subskills of particular importance are
Shortcomings in one or more of these subskills can greatly affect a person's spelling ability. Edublox programs are effective in overcoming spelling problems by addressing these underlying shortcomings.
