After reаding the fоllоwing excerpt frоm the аrticle, Appropriаte Strategies and Materials that Address the Prevention, Identification, and Remediation of Reading Difficulties, answer the following question. List at least five characteristics of students with reading disabilities that are different when compared to proficient readers. Two types of students with reading problems that school psychologists and educators are likely to encounter are students with IQ-reading achievement discrepancies and students with a combination of low ability and low reading achievement. Students who have IQ-reading achievement discrepancies tend to have average to high average IQ and listening comprehension scores (Aaron & Joshi, 1992). Children with developmental dyslexia are included in this group of poor readers. Dyslexia is often associated with some neurological impairment that results in poor word recognition skills including phonological processing. Slow rate of reading, erratic oral reading, misuse of function words and suffixes, and reading comprehension difficulties on timed reading tasks are among the symptoms commonly associated with dyslexia (Aaron & Joshi, 1992). Low ability readers make up the largest number of poor readers. They tend to have lower than average IQ and have below grade level listening comprehension, word recognition, and reading comprehension performance. Although we tend to classify children with severe reading problems as low ability readers or IQ-achievement discrepant readers, current research indicates that there are no significant differences between these two groups of readers on how they develop reading precursor skills (Wristers, Francis, Foorman, Fletcher, & Swank, 2000). Earlier research conducted by Stanovich and Siegal (1994) also suggested that IQ did not predict reading difficulties among low ability (garden variety readers) and IQ-discrepant readers. Instead, they found that phonological core variables were better predictors of reading skills. Therefore, differential diagnoses based on IQ scores do not yield different growth patterns in reading development. For this reason, the remainder of this section will describe poor readers according to specific cognitive processes and behaviors they exhibit rather than according to diagnostic categories. Poor readers with word recognition difficulties generally over rely on textual cues such as pictures and other words to identify words in a passage that are unknown to them (Kim & Goetz, 1994). Overusing textual cues to identify unknown words reduces the likelihood of transforming unknown words into sight words (Pressley, 1998). Many errors are made when children use semantic contextual approaches rather than sounding out words. Children need opportunities to sound out words even if this means they have to struggle (Adams & Henry, 1997). This may be easier said than done as many children do not know how to begin to sound out words. Some poor readers have limited letter-level knowledge or an understanding of the alphabetic principle. Typically, these types of readers are limited to being able to sound out only the beginning letter of a word. The inability to sound out words can be attributed to phonological processing difficulties. Weak phonological processing accounts for the largest population of students classified as having dyslexia or individuals with severe word recognition difficulties (Pressley, 1998). Phonological awareness is a crucial component to becoming literate. This has been verified through studies that examined long-term effects of phonological awareness training in preschool and kindergarten on subsequent reading achievement performance of first, second, and third graders (Ball & Blachman, 1991; Byrne & Fielding-Barnsley, 1993). Phonemic awareness is knowing that spoken language is made up of discrete, operable sounds. Rhyme production, sound blending, sound deletion, sound substitution, and sound segmenting are among the many ways individuals can operate on spoken words. Developmentally, children begin with rhyme activities and then progress to segmenting sounds in words. Among phonemic awareness exercises, phonemic segmentation is the best predictor of word identification for primary grade children (Nation & Hulme, 1997). An example of a phonemic segmentation exercise would be to pronounce a word such as "cat" and ask a child to say each sound as three separable sounds in the word such as /c/ /a/ /t/. Some children develop phonemic awareness through literacy experiences at home before entering school while others have limited exposure to print and role models who engage in reading and writing. Some children, regardless of their environmental conditions, struggle with grasping phonemic awareness. Thus, children who lack phonological skills and have a limited vocabulary will have difficulty phonologically "recoding" letters back into their constituent sounds when they encounter print (McCormick, 1999). When most children initially encounter a printed word, they go through a process of sequentially decoding the word by attempting to make letter-sound conversions. Phonological recoding occurs as children check to see if the word they made matches a word that has been stored in their memories (Daneman, 1991). At advanced stages of this process, children learn to decode words hierarchically. Hierarchical decoding involves using letters in words to cue the sounds of other letters. For example, using the "e" at the end of the word "came" to say the "a" as a long vowel sound. Related to phonological recoding is orthographic processing. Orthographic processing refers to recognizing and remembering letters which includes noting sequences of letters in words and being able to distinguish among spelling patterns of words. Although smaller in population compared to those with phonological deficits, some children with reading and spelling problems have difficulty processing words orthographically (Stanovich & West, 1989). Children need to become automatic at recognizing words to free up their cognitive energies to gain meaning from text. Poor readers not only struggle with recognizing words in text but also have difficulty suppressing irrelevant information in text which places limitations on the use of their short term capacity for comprehending printed material (Pressley, 1998). These students have particular difficulty grasping an understanding of texts that contain words with multiple meanings (McCormick, 1999). Beyond the word reading level, poor readers have difficulty making inferences about the content presented in text. Poor readers do not connect ideas well and may not grasp the conceptual nature of the material. Problems with making inferences are partly due to poor readers' lack of prior knowledge about the content. On the other hand, good readers read more and gain more knowledge each time they read material. Good readers also have a repertoire of comprehension strategies to help them construct meaning from text. Poor readers know very few, if any, strategies that aid in the construction of meaning from text and strategies for monitoring understanding of text (Pressley, 1998).
