THE INFLUENCE OF SOCIOECONOMIC STATUS ON THE PREDICTABILITY OF COLLEGE PERFORMANCE

Although numerous studies have examined the validity of scholastic aptitude measures as predictors of college performance for black and white students, few studies have investigated the validity of these predictors for different socioeconomic levels within a racially homogeneous population. To study the influence of socioeconomic status (SES) on the predictability of college performance, a sample of 1,631 white freshmen attending a large urban university was divided into homogeneous subgroups on each of three measures: (a) family income, (b) father's occupation, and (c) mother's education. Verbal and Quantitative Scholastic Aptitude Test scores and high school class rank were used to predict freshman grade-point average within each subgroup. For all three socioeconomic measures, lower cross-validated multiple correlations were associated with lower levels of SES. Possible explanations for these results are discussed and implications for research are presented.     

Students classified as LD who received course substitutions for the college foreign language requirement: a replication study

This replication study examined whether 158 college students classified as learning disabled (LD) who were granted course substitutions for the foreign language (FL) requirement would display significant cognitive and academic achievement differences when grouped by levels of IQ-achievement and achievement-achievement discrepancy and by level of performance on an FL aptitude test (Modern Language Aptitude Test; MLAT), phonological/orthographic processing measures, and in FL courses. The results showed that there were few differences among groups with differing levels of IQ-achievement or achievement-achievement discrepancy (i.e., < 1.0 SD, 1.0-1.49 SD, and > 1.50 SD) on MLAT and American College Testing (ACT) scores, graduating grade point average (GPA), or college FL GPA. The results also showed that between groups who scored at or above versus below the 15th percentile (i.e., < 1.0 SD) on the MLAT, there were no differences on measures of graduating GPA, college FL GPA, native language skill, ACT score, and Verbal IQ. Demographic findings showed that 44% of these petition students met a minimum IQ-achievement discrepancy criterion (> or = 1.0 SD) for classification as LD. These findings suggest that many traditional assumptions about LD and FL learning are likely to be false.

Differences required for significance between Wechsler verbal and performance IQs and WIAT subtests and composites: The predicted-achievement method

This paper provides tables of critical values for determining statistically significant discrepancies between Wechsler Verbal/Performance IQ and WIAT subtest and composite scores based on a predicted-achievement method. It is recommended that these tables be used when a statistically significant and diagnostically meaningful Verbal IQ-Performance IQ discrepancy exists rendering either of these IQs a better estimate of a student's ability than the Full Scale IQ. Issues regarding the use of discrepancy formulas in the assessment and diagnosis of learning disabilities are discussed, and basic considerations for using the critical values tables are provided.     

Concurrent validity of the Stanford-Binet: Fourth edition and Kaufman assessment battery for children with learning-disabled students

This study examined the concurrent validity of the composite and area scores of the Stanford-Binet Intelligence Scale: Fourth Edition (SBIV) and the Mental Processing Composite and global scale scores of the Kaufman Assessment Battery for Children (K-ABC). The tenability of interpreting the SBIV using the fluid/crystallized model, as suggested by the authors, was also considered. The subjects were 30 Black, learning-disabled elementary school students. Results of a t test indicated that the Mental Processing Composite score of the K-ABC was significantly higher than the SBIV Composite score. Moderate to high correlations were obtained when SBIV composite and area scores were compared to K-ABC composite and scale scores, reflecting a positive relationship between the two tests. The measures of fluid abilities (K-ABC Composite score; SBIV Abstract/Visual Reasoning) were highly correlated. The results of a multiple regression analysis indicated a moderate degree of correlation among the measures of crystallized ability (K-ABC Achievement; SBIV Verbal Reasoning and Quantitative Reasoning). The findings of this study demonstrated adequate concurrent validity for the SBIV. In addition, the results provided limited support for describing test results utilizing the fluid/crystallized interpretation model. Further research is suggested in order to examine other validity issues, such as classification of special education students and the SBIV's relationship to other similar instruments.     

The Value of Amount of Tardiness and Absence for Direct and Differential Prediction of Academic Success

The purpose of this study was to investigate the relationships among nine measures of attitude toward quantitative concepts and verbal and quantitative aptitude. Subjects were 353 graduate students enrolled in educational research courses. The attitude measures consisted of nine factor scores drawn from a seman tic differential instrument; the aptitude measures were the Graduate Record Examination Verbal and Quantitative scores. Canonical correlation was used to relate the attitude to the aptitude measures. Two significant canonical variates were obtained. The first showed a moderate relationship between positive attitudes toward quantitative concepts and high quantitative aptitude. The second indicated a slight relationship between negative attitudes toward quantitative concepts and high verbal aptitude.     

WIAT subtest and composite predicted-achievement values based on WISC-III verbal and performance IQs

Critical values tables for determining significant differences between Wechsler IQs and WIAT subtests and composites based on a predicted-achievement method are provided in the WIAT manual for the Full Scale IQ and have been constructed recently for Verbal and Performance IQs (Flanagan & Alfonso, 1993). In order to use these tables, however, a predicted achievement score(s) is required. The process of calculating predicted-achievement scores is time-consuming and may result in errors, especially when more than one ability-achievement comparison is warranted. The present paper provides tables of WIAT subtest and composite predicted-achievement standard scores based on WISC-III Verbal and Performance IQs. These tables allow examiners to determine quickly ability-achievement discrepancies based on WISC-III Verbal or Performance IQs when they are used in conjunction with the critical values tables provided in our earlier article. These tables are most useful for the accurate assessment and diagnosis of learning disabilities.

Personality,Intelligence Components and Foreign Language Attainment

Approximately 1200 children from the Irish Republic were tested for various intelligence abilities, attainment in Irish (taught as a second language), personality traits of psychoticism, neuroticism and extroversion and attitude to learning foreign languages. Females had a significantly higher N score and had a significantly more positive attitude towards learning second languages and males had a significantly higher P score. The personality measures were not strongly related to the cognitive measures; anxiety, for example, does not appear to have an adverse effect on performance. There were low but positive correlations between attitude towards foreign language learning and the total score obtained in the Irish test. It is suggested that individuals have a more positive attitude towards subjects they are good at; hence the attitude could be influenced by innate ability. Attitude towards learning foreign languages also had low but significant correlations with some of the other cognitive tests, e.g. the English Spelling and Verbal Fluency tests. The results were very similar for both the primary and secondary school children. Age does not appear to influence personality measures during this period of childhood and adolescence.     

Academic Admission Requirements as Predictors of Counseling Knowledge,Personal Development,and Counseling Skills

The authors investigated whether undergraduates' scores on the Verbal and Quantitative tests of the Graduate Record Examinations and their undergraduate grade point average can be used to predict knowledge, personal development, and skills of graduates of counseling programs. Multiple regression analysis produced significant models predicting total Skilled Counselor Scale (S. Urbani et al., 2002) scores and total Counselor Preparation Comprehensive Examination (Center for Credentialing and Education, 2005) scores. No significant prediction model was found for the Counselor Skills and Personal Development Rating Form (M. P. Wilbur, 1991) Personal Factors scores. It is concluded that educators should recognize the limitations of these admission criteria and assign a weight to them on the basis of what they can and cannot predict.     

The performance of preschoolers with speech/language disorders on the McCarthy Scales of Children's Abilities

The McCarthy Scales of Children's Abilities (MSCA) was used to evaluate the performance of preschool children with speech/language disorders. Preschoolers were screened first for normal intelligence using the Performance scale of the Wechsler Preschool and Primary Scale of Intelligence (WPPSI). Preschoolers with speechllanguage disorders had significantly lower scores on all scales of the MSCA (Verbal, Perceptual/Performance, Quantitative, and Memory), except the Motor scale. They also had an average 20-point lower GCI than the control children. An analysis of the scores of the speechllanguage group on subtests revealed difficulty in short- term auditory memory skills but not in short-term visual memory skills. Deficits in categorical thinking skills and verbal expression skills were also evident. Characteriza- tion of learning disabilities in preschoolers with speechllanguage disorders is discussed.     

iSpy: seeing what students really do online

Numerous studies have shown that college students use computers, the internet, and social networking websites (SNS) at high rates; however, all of these studies have relied on self-report measures of technology use. Research in other areas of human behavior has shown that self-report measures are considerably inaccurate when compared to actual behaviors. This study produces more effective estimates of the time that college students spend on computer and internet activities by using logging software to collect data on actual use. A sample of 45 students installed a computer monitor for two months. The results show that social networking was the most popular computer activity, with Facebook being the most popular SNS. Furthermore, the results also suggest that students may be able to somewhat regulate their computer use in ways that could benefit them academically. For instance, students spent significantly more time using the university's learning management system when classes were in session and less time watching videos. Although there are some limitations of monitoring computer usage, such monitoring is an effective method of evaluating frequency of use.     

Evaluating Change and Stability in Learning Style Scores: a methodological concern

Learning styles are purported to be relatively stable characteristics with some change or development expected. Some studies using Kolb's Learning Style Inventory (LSI) have reported significant positive test‐retest correlations of LSI scores or nonsignificant repeated‐measures ANOVAs and concluded that learning styles are stable. This study examined stability and change on Kolb's revised Learning Style Inventory (LSI‐1985) using 152 participants at two points in time separated by about 10 weeks. A variety of statistics were used to evaluate stability and change in LSI‐1985 scores for the four subscales and two dimensions and the four learning styles. The use of test‐retest correlations, differences between means and other methods emphasising group effects were criticised. It was recommended that researchers also analyse and report the stability and change of style categories directly, not just score changes. These comments are also applicable to other learning style measures such as the Learning Style Questionnaire.     

Predictors of Success on the Counselor Preparation Comprehensive Examination

This study examined the relationship between 403 counseling graduate students' scores on the Counselor Preparation Comprehensive Examination (CPCE; Center for Credentialing and Education, n.d.) and 3 admissions requirements used as predictor variables: undergraduate grade point average (UGPA), Graduate Record Examinations (GRE) General Test Verbal Reasoning (GRE‐V) score, and GRE General Test Quantitative Reasoning (GRE‐Q) score. Multiple regression analyses revealed that all predictor variables accounted for somewhat limited, yet significant variations in the CPCE‐Total scores (R² = .21). Results indicated that UGPAs, GRE‐V scores, and GRE‐Q scores are valid criteria for determining counseling graduate student success on the CPCE.     

WISC-III correlations with the WIAT

Correlations between WISC-III IQs and Index scores with the eight achievement subscales of the WIAT were investigated for a sample of 202 students with specific learning disabilities, 115 students with mental retardation, and 159 students who failed to qualify for special education services (total N = 476). Corrected correlations between the WISC-III Full Scale IQ and WIAT subtests indicated differences with the correlations reported in the WIAT manual. Interestingly, our relationships were generally higher than those previously reported. Only on one subtest, Basic Reading, were significantly lower correlations than those reported in the WIAT manual present. Correlations between the Verbal Comprehension and Perceptual Organization Index scores and WIAT subtests were almost all lower than those calculated between the Verbal and Performance IQs and WIAT subtests. Implications are discussed, especially those involving the use of correlations between ability and achievement measures in regression formulas.     

The relationship between the Differential Ability Scales (DAS) and the Wechsler Intelligence Scale for Children—Third Edition (WISC-III) for students with learning disabilities

As part of a mandated three-year reevaluation, the Differential Ability Scales (DAS) was administered to 53 children identified as having a learning disability approximately 3 years after each had been administered the Wechsler Intelligence Scale for Children—Third Edition (WISC-III). The DAS's General Conceptual Ability score (GCA), and Verbal and Spatial Cluster scores were nonsignificantly different from the WISC-III's Full Scale, Verbal, and Performance scores. The Nonverbal Reasoning score of the DAS (a measure of Fluid intelligence not assessed by the WISC-III) was significantly different from both the Verbal and Performance scores. High correlations were found between the similar constructs on the two tests. Approximately 96% of the students obtaining a certain classification from the WISC-III obtained a comparable classification from the DAS. © 1996 John Wiley & Sons, Inc.     

Newborn and preschool predictors of second-grade reading scores: an evaluation of categorical and continuous scores

This study examined how the development of foundation skills in speech perception, language, short-term memory, and family demographics and activities in the home environment influence the development of reading skills. Data from 96 children participating in a longitudinal research project were used. It was hypothesized that measures of specific foundation skills in the preschool period and measures of family demographics and home environment could be used to identify children's reading abilities. As expected, most of the foundation skills were found to be related to and predictive of reading scores. Event-related potential (ERP) measures of speech perception, which have previously been found to be predictive of reading abilities, and measures of family and home activities and language measures were related to reading scores. Verbal short-term memory scores contributed little to the prediction of reading scores. These variables influenced the results whether they were used to discriminate reading groups or to predict a continuum of reading scores, but there were large differences in the amount of variance accounted for. More variance was accounted for in the group analyses than in the continuum analyses.     

The intellectual profile of abused and neglected children in the Philippines: An analysis of SB5 IQ scores of sexually abused,physically abused and neglected children

Child abuse and neglect have been associated with cognitive deficits, among other effects on child development. This study explores the prediction that child abuse and neglect has an impact on Stanford-Binet Intelligence Scales 5th Edition (SB5) IQ scores, in relation to gender, age and type of abuse experienced. 300 children with experiences of abuse and neglect were included in the study, comprising 100 sexually abused, 100 physically abused and 100 neglected children. Overall, all scores on the SB5 were found to be significantly lower than the minimum average scores on the test. Verbal IQ (VIQ) scores were likewise found to be significantly lower than Nonverbal IQ (NVIQ) scores. Full Scale IQ (FSIQ) scores did not reveal heterogeneity when gender was factored in. Age and type of abuse (with a moderate effect size) on the other hand, showed significant differences among groups. Statistical analyses of SB5 Factor Index Scores revealed that abused children, in general, have significantly higher Visual-Spatial Processing (VS) and Quantitative Reasoning (QR) scores and lower scores in Knowledge (KN). There was a large effect size found in such an analysis. Age (with a large effect size), gender and type of abuse (with moderate effect sizes) give significant variations to this obtained profile.     

Discourse measures for Basque summary grading

In the context of Learning Technologies, the need to be able to assess the learning and domain comprehension in open-ended learner responses has been present in artificial intelligence and education since its beginnings. The advantage of using summaries is that they allow teachers to diagnose comprehension and the amount of information remembered from text in the learning process. This study addresses the issue of automatically obtaining overall discourse scores from surface discourse measures for Basque language. Global measures have been studied for cohesion, adequacy and use of language. The approach taken was to estimate the presence of the automatically gathered surface discourse measures in expert grading decisions in cohesion, adequacy and use of language. As a consequence, three grading decision-making regression models were obtained to estimate overall grades from text written in Basque. Next, the obtained regression models were tested in corpus-containing summaries written by learners with different degrees of summarisation maturity. The results show that the obtained grading frameworks significantly reflect human decisions and are able to discriminate summarisation maturity differences.
