The relationship between achievement and IQ in students with learning disabilities

To investigate the relationship between achievement and IQ in the learning-disabled (LD) population, changes in the IQ scores of LD students from the early elementary grades to the high school grades were studied. The intercorrelations among those IQ scores and a variety of achievement scores were then explored for the purpose of ascertaining causal relationships. The results were interpreted as support for the contention that the underachievement of LD students (in particular, reading underachievement) plays a predominant causal role in the achievement-IQ relationship in this population.     

The effect of using laptops on the spelling skills of students with learning disabilities

The current study examined the effect of using laptops on the spelling skills of students with learning disabilities (LD). It was conducted as part of the Israeli “Katom” (A Computer for Every Class, Student, and Teacher) Program. Participants included 93 Hebrew-speaking students with LD aged 13–16, who attend 10 special education classes in a regular middle school. We examined whether the experimental group using laptops showed significant differences in the number of their spelling errors as a result of the intervention on their pre- and post-spelling tests. We also investigated whether there would be differences on the number of spelling errors between the experimental and control groups, as measured by their pre- and post-spelling test results. The findings indicated that the participants in the experimental group significantly improved their spelling skills as opposed to the control group. It seems that the use of laptops in special education classes can enhance the spelling skills of students with LD.     

The relationship between the phonological strategies employed In reading and spelling

This paper summarises a longitudinal study which examined the relationship between the abilities of young children to read and spell phonologically. Empirical evidence of Bryant and Bradley (1980) and Cataldo and Ellis (1988) to show that children acquire the ability to use a phonological strategy for spelling before the ability to use an equivalent strategy for reading is confirmed. Implications for the teaching of reading are discussed.     

Computer-based reading and spelling practice for children with learning disabilities.

To examine the effects of computer-based reading and spelling practice on the development of reading and spelling skills, a pretest-training-posttest experiment was conducted in The Netherlands. Eleven girls and 17 boys with written language disorders (on the average, 9 years, 7 months old and performing 2 grades below age expectancy) practiced hard-to-read words under three conditions: reading from the computer screen, copying from the screen, and writing from memory after presentation on the screen. For all words, whole-word sound was available on call during practice. To assess learning effects, both a dictation and a read-aloud task were administered in which nonpracticed control words were also presented. During training, the computer kept record of several aspects of the pupils' learning behavior. It was found that copying words from the screen resulted in significantly fewer spelling errors on the posttest than writing words from memory, and that both forms of spelling practice led to fewer spelling errors than only reading words during practice. All three forms of practice improved to the same degree both the accuracy and fluency of reading the practiced words aloud. The way in which spelling and reading practice, in combination with speech feedback, support the development of phonological skills in children with written language disorders is highlighted in the discussion.     

Comparing the self-concept of students with and without learning disabilities

This study compared self-concept in 50 middle school children with learning disabilities (LD) and 70 of their peers without LD. The students, primarily Hispanic, completed the Piers-Harris Children's Self-Concept Scale, and each obtained a score in six subdomains. Differences were found between the groups on the Intellectual and School Status and Behavior subscales, with students without LD scoring higher on both scales. There was no difference between groups on global self-concept. The limitations of this study are identified, and directions for future research are provided.     

The relationship of phonological awareness, rapid naming, and verbal memory to severe reading and spelling disability.

The present study examined the relationship of phonological awareness, naming speed, and verbal memory to the scores obtained from five tests assessing word attack, word identification, reading comprehension, and spelling skills in 54 children with severe reading disabilities (48 boys and 6 girls; M age = 9 years, 7 months). Multiple regression analyses indicated that the best predictor of achievement across the five academic tests was the Verbal Comprehension factor from the Wechsler Intelligence Scale for Children-Revised. Age, socioeconomic status (SES), and externalizing behavior problems were also significant predictors of achievement, depending on the academic measure. After controlling for age, SES, behavior problems, and intelligence, the phonological awareness task added significantly to the prediction of word attack, spelling, and reading comprehension scores; rapid letter naming added significantly to the prediction of word identification and prose passage speed and accuracy scores; and a word-list memory task added significantly to the prediction of word recognition scores. These results suggest that several independent processes interact to determine the extent and severity of reading problems.     

The relationship between school belonging,sibling aggression and bullying involvement: implications for students with and without disabilities

Bullying is grounded in the interactions between an individual and complex social–ecological systems. Therefore, bullying involvement is not just confined to the classroom or school. Recent research suggests that sibling aggression may be a predictor for peer-level aggression. These findings may be more relevant for students with disabilities because studies suggest that students with disabilities are disproportionately involved in the bullying dynamic. Therefore, this study explored the intersection between sibling aggression and school belonging on bullying, victimisation and fighting for 14,508 students, including 1183 students with disabilities and 13,325 students without disabilities in grades 6 through 12. As hypothesised, students with disabilities reported higher levels of victimisation, bullying and fighting. Additionally, high levels of school belonging partially buffered fighting and bullying behaviours for students with and without disabilities. These findings demonstrate the importance of establishing an inclusive and safe environment for school-aged youth.     

The effect of extra time on reading comprehension scores for university students with and without learning disabilities

The purpose of this study was to examine the effects of extra time on the ability of university students with and without learning disabilities to complete a reading comprehension test under timed and extra-time conditions. The participants were 16 students identified as having learning disabilities and 15 normally achieving students, all attending the University of California. The Nelson-Denny Reading Comprehension and Reading Rate Test was used. Percentile ranks were obtained for reading rates on individuals, and for comprehension scores under timed and extra-time conditions. The major findings of this study were that there is a significant difference between scores obtained by students with learning disabilities and by normally achieving students under timed conditions and that there are no significant differences in test performance between students with learning disabilities and normally achieving university students when students with learning disabilities are provided extra time. Normally achieving students did not perform significantly better with extra time.     

Innovative technology for secondary students with learning disabilities.

During the 1980s, innovative use of technology was equated with microcomputer instruction. In the 1990s, a different kind of technology--videodisc instruction--has great potential for application in secondary special education. By examining its day-to-day use in naturalistic settings, this study builds on previous research with a specific videodisc program in fractions. Participants were seven secondary teachers of students with learning disabilities. Researchers measured the program's level of implementation, teacher reactions, and student achievement. Results were generally positive in all areas, with a surprisingly high acceptance of the program by the seven teachers.     

Visual and auditory coding confusability in students with and without learning disabilities

The nature of visual and auditory coding processes in students with learning disabilities (SLDs) and student controls (SCs) was examined with a letter-matching task on four types of successively presented letter pairs: identical (A,A), visually confusable (P,R), auditorily confusable (F,S), and neither visually nor auditorily confusable (N,T). Two delay intervals (0 and 2 seconds) were used between the presentation of the first and second letters. Analysis of decision latencies on the nonidentical letter pair trials revealed that with initial exposure to the task, the SLDs responded more slowly than SCs, but their general confusability patterns (visual and auditory) were similar. With additional practice, overall decision latencies were comparable for the two groups, while confusability differences emerged: SCs showed maximal visual confusability at a 0-second delay and maximal auditory confusability at a 2-second delay, while SLDs did not. Evidently, SLDs make less extensive use of visual and auditory coding processes compared to SCs.     

Postsecondary education for students with learning disabilities

Increasingly, students with learning disabilities are attending community colleges and traditional 4-year colleges and universities. This article presents the results of a review of the literature on services available or recommended for students with learning disabilities. The results suggest that postsecondary institutions have begun to provide a wide array of services to these students. There is little empirical evidence, however, on the effectiveness of those services. An agenda for future research is also discussed.     

Significant predictors of test anxiety among students with and without learning disabilities

In the present study, the relationship between students with and without learning disabilities (LD) and different aspects of test anxiety was examined on a new multidimensional measure of test anxiety. A sample of 774 elementary and secondary school students--195 students with LD and 579 students not identified with LD--completed the Test Anxiety Inventory for Children and Adolescents (TAICA), a new multidimensional measure of test anxiety for elementary and secondary school students in Grades 4 through 12. Examination of the factor structure of the TAICA scores across LD status to determine whether accurate test score interpretation was possible revealed that the majority of the coefficient of congruence values between each pair of six corresponding factors of the TAICA (Cognitive Obstruction/ Inattention, Performance Enhancement/Facilitation Anxiety, Physiological Hyperarousal, Social Humiliation, Worry, and Lie) and the Total Test Anxiety factor were above .90, and the salient variable similarity index values were statistically significant, suggesting that the factor structure of the TAICA was similar across groups. The results of seven multiple regression analyses revealed that LD predicted higher Cognitive Obstruction/Inattention and Worry scores and lower Performance Enhancement/Facilitation Anxiety and Lie scores. Implications of the findings for school personnel who work with students with LD are discussed.     

Small-group instruction for students with learning disabilities: observational and incidental learning.

This study evaluated the effectiveness and efficiency of constant time delay (a near errorless learning procedure) in a small-group instructional arrangement. Three fifth-grade students with learning disabilities were taught to recognize multisyllabic basal vocabulary words. A multiple-probe design across behaviors (word sets) was used to evaluate the procedure. Following instruction on each word set, students were assessed on their ability to recognize their own target words, recognize observational words, spell both target and observational words, and define both target and observational words. The results indicated that the constant time-delay procedure was reliably implemented and was effective in establishing criterion-level performance for all students with extremely low error percentages.     

Perceptual organization,phonological awareness,and reading comprehension in adults with and without learning disabilities

It is not clear from research whether, or to what extent, reading comprehension is impaired in adults who have learning disabilities (LD). The influence of perceptual organization (PO) and phonological awareness (PA) on reading comprehension was investigated. PO and PA are cognitive functions that have been examined in previous research for their roles in nonverbal LD and phonological dyslexia, respectively. Nonverbal tests of PO and non-reading tests of PA were administered to a sample of adults with postsecondary education. Approximately two thirds of the sample had previously been diagnosed as having LD. In a multiple regression analysis, tests of PO and PA were used to predict scores for tests of reading comprehension and mechanics. Despite the nonverbal nature of the perceptual organizational test stimuli, PO strongly predicted reading comprehension. Tests of PA predicted decoding and reading speed. Results were interpreted as supporting the hypothesis that integrative processes usually characterized as nonverbal were nonetheless used by readers with and without disabilities to understand text. The study’s findings have implications for understanding the reading of adults with learning disabilities, and the nature of reading comprehension in general.     

Wage differentials between college graduates with and without learning disabilities

Wage differential studies examining legally protected groups typically focus on gender or racial differences. Legislation also fully protects individuals with learning disabilities (LD). This article is the first to decompose wage differentials between adults with and without LD. An original data set of college graduates with documented LD was constructed, and these individuals were compared to a control group from the National Longitudinal Survey of Youth (NLSY). Our results show that much of the observed lower wages for individuals with LD is due to differences in productivity characteristics. However, there is an unexplained portion of the wage gap that could possibly be considered wage discrimination against individuals with LD. This possibility seems smaller due to the fact that the subsample of the employers who knew of the employee's learning disabilities did not appear to pay significantly lower wages to these individuals. Alternative hypotheses are discussed, as are sample-specific issues.     

Predicting performance on academic and non-academic tasks: A comparison of adolescents with and without learning disabilities

Previous research suggests that adolescents with learning disabilities (LD) are less accurate in predicting academic performance than normally achieving (NA) adolescents and display a tendency to overestimate their level of performance (e.g., Klassen, 2007). However, no studies have been conducted investigating whether this overestimation is specific to academic contexts or a phenomenon that extends across domains. Ninety-four adolescents (46 LD, 48 NA) predicted their performance on a spelling task and on a ball-throwing task. Results revealed group differences in performance calibration across domains with adolescents with LD showing an overestimation of ability on the spelling and ball-throwing tasks, and NA adolescents demonstrating more precise self-appraisals. Additionally, the accuracy of non-academic performance predictions remained stable with increasing difficulty in the NA group whereas the adolescents with LD demonstrated a decrease in accurate performance prediction as the difficulty level increased.     

Differences in transitional needs of high school students with and without learning disabilities

Studies investigating the post-high-school vocational status of individuals with disabilities have frequently found that these individuals are more likely to be unemployed, underemployed, or employed part-time, when compared to nondisabled peers. Transition programs are needed for adolescents with disabilities to facilitate their vocational success. The current study surveyed 80 high school students with learning disabilities (LD) and 80 nondisabled (NLD) peers to determine their transitional needs. Results indicated that (a) more students with LD than NLD students are involved in transition programs; (b) career goals were established by the majority of both groups; (c) parents provided most of the assistance in making career decisions; and (d) twice as many NLD students as students with LD wanted to go to college, while twice as many students with LD as NLD students wanted to enter the job market. More students with LD than NLD students were aware of vocational rehabilitation (VR) services, but the number was still below 50%. The majority of the information about VR services came from the school.
