The purpose of this study was to compare and analyze test scores on the Woodcock-Johnson Psycho-Educational Battery (Battery) and the Wechsler Intelligence Scale for Children -- Revised (WISC-R) for a sample of subjects classified as learning disabled and a sample of subjects classified as gifted and talented. Subjects were randomly selected and included 51 school-identified learning disabled students and 46 school-identified gifted and talented students. All subjects were administered the Woodcock-Johnson Tests of Cognitive Ability (WJTCA), the Woodcock-Johnson Tests of Achievement (WJTA) and the WISC-R. The specific areas of investigation for each sample included: (a) performance on the Achievement-Aptitude Profile of the Battery, (b) comparability of full scale scores, (c) performance on the Cognitive clusters of the Battery, (d) performance on the Achievement clusters of the Battery, and (e) the magnitude of Verbal-Performance Scale Score discrepancies on the WISC-R. Results indicated that the majority (74.5%) of the subjects classified as learning disabled and a few (10.9%) of the subjects classified as gifted and talented evidenced a moderate or severe deficit on the Achievement-Aptitude Profile. The subjects classified as learning disabled scored significantly higher on the Full Scale score of the WISC-R than on the full scale score of the WJTCA, while the difference between full scale scores was not significant for the subject classified as gifted and talented. An important finding was that scores obtained on the Reasoning cluster were invalid for subjects in both samples. Further analyses indicated that the alternative clusters, Oral Language and Broad Reasoning (Woodcock, 1983) provided a more accurate appraisal of abilities for each sample. Overall, the study provided insights regarding test performance on the Battery and the WISC-R for these two diverse samples.

Within each classroom, many children excel academically while others struggle. Some students' difficulties are such that they require placement into educational programs different from grade level core and perhaps delivered outside of general education classrooms. For many, special education programs are the lifeline to reach their innate potential. For others misplaced into special education, their opportunities may be truncated. For the past 40 years (Dunn, 1968), disproportionate representation of minority children in some disability categories has been a problem. Educators commonly ask "Is a child's difficulties due to language differences or a learning disability?" One key area of confusion relates to the cognitive assessment of English language learner (ELL) students. While it is understandable that scores generated by English cognitive tests will not reflect an ELL child's true abilities, less is known about the appropriate use of native language (Spanish) cognitive assessments. This study examined the performance of ELL general education students on the Bateria III: Pruebas de habilidades cognitivas, a Spanish parallel to the Woodcock-Johnson JJI. The performance of 34 third- and fourth-grade participants, 16 who have received native language literacy development (NLD), and 18 who have received English language development, was compared to the normative sample's (monolingual Spanish speakers) General Intellectual Achievement (GIA) score, subtest and cluster scores. ANOVA and t test analyses indicated both ELL groups scored significantly lower than the normative sample on GIA, short-term memory, long-term retrieval and crystallized intelligence and higher on auditory processing. Thus, the Bateria's scores from these factors may underestimate the abilities of ELL students. Correlation analyses were conducted to examine the relationships between language proficiency, acculturation and performance. No significant relationships were found. The last analysis compared subtest mean scores of the ELD group to Flanagan and Ortiz's (2001) predicted pattern of performance on the Culture-Language Interpretive Matrix (C-LIM) for diverse individuals when tested on the WJ-HI. The score patterns of the ELD group did not follow the predicted pattern. A new arrangement of the Bateria's subtests on the C-LIM is suggested. These findings highlight the need for more research to understand how ELL students perform on Spanish cognitive assessments.

Relatively recent federal education initiatives, such as No Child Left Behind (NCLB; 2001), have focused on school accountability for student achievement including achievement of traditionally at-risk populations, such as students in special education, students from low-income or high poverty areas, and students who speak English as a new second language. Additionally, these federal initiatives also mandate that all students take the same test measuring grade level standards despite research that has demonstrated that students from at-risk populations are sometimes at a disadvantage on high-stakes tests. Furthermore, initiatives such as NCLB are often at odds with other education initiatives such as IDEA, which states that students in special education should be tested at their respective level. Therefore, the current study proposed to examine the relationship between Cattell-Horn-Carroll cognitive abilities and performance on a state-wide high-stakes achievement test. There currently are no studies examining such a relationship. This study used Multivariate Regression Analysis, in order to investigate the relationship between CHC cognitive and achievement abilities and performance on a state-wide high-stakes achievement test, namely the ISTEP+, with 45 children who had been referred for a psychoeducational evaluation to determine special education eligibility and who had also taken the ISTEP+. No statistically significant result was found between the WJ-III-COG broad CHC abilities and performance on the English/Language Arts and Math performance of the ISTEP+. Furthermore, no statistically significant result was found between the WJ-III-ACH and Math performance on the ISTEP+. However, a statistically significant result was found between the WJ-III-ACH Passage Comprehension subtest and the English/Language Arts portion of the ISTEP+. The results indicated that students who had higher scores on the Passage Comprehension subtest also had higher scores on the English/Language Arts portion of the ISTEP+. The current study took a step forward in the area of the relationship between CHC and academic achievement, particularly state-mandated high-stakes testing given the dearth of research in this area. Given the data from the current study indicating a statistically significant relationship between Passage Comprehension and English/Language Arts from the ISTEP+, the current study has practical implications for school psychologists, especially when school psychologists are being asked to make predictions regarding a student’s academic achievement. Results of the current study might help elucidate reading problems and recommended interventions for those reading problems. / Department of Educational Psychology

Magister Artium (Psychology) - MA(Psych) / South Africa's Language-in-Education Policy is one of additive multilingualism, but in reality this policy is not adhered to, in that most black children are being educated through the medium of English from Grade 4. This type of instruction affects the development of academic language proficiency in their primary language, as these children are not engaging in cognitively demanding tasks in their primary or first language. The Woodcock Muñoz Language Survey (WMLS) is a test to assess academic language proficiency in Additive Bilingual Education, and is extensively used in the United States of America (USA) for this purpose. It is important to note that the proposed study is a sub-study of a larger study, in which the original WMLS (American-English version) was adapted into English and Xhosa, to be used in South Africa to assess additive bilingual programmes. For this sub-study, the researcher was interested in examining the overall equivalence of the adapted English version of the WMLS. Owing to insufficient tests evaluating academic language proficiency in the South African context, the significance, as well as the overall aim, of the study is to ensure that the issues of group difference and item bias have been assessed to ensure that the adapted English version of the WMLS is suitable to be used across English first-language and Xhosa first-language speakers. Because this is a sub-study, the researcher (of the sub-study) has conducted an exploratory quantitative study with the use of Secondary Data. The researcher has used the framework of equivalence as a theoretical framework in order to examine the research question. Given the use of existing data, the procedures of the collection of the data by the researcher of the larger study have been outlined in the Methodology section of the present study. The sample consisted of 198 English and 197 Xhosa first-language speakers. / South Africa

This study identified a sample of children with specific learning disabilities according to Public Law 94-142 criteria. The primary purpose of the study was to examine whether sample member's intravariability of WISC-R subtest scaled scores was related to their reading achievement gain. A second purpose was to determine if any relationship existed between intelligence and reading achievement gain. Eighty-four Resource placed elementary students composed the study sample. They ranged from six to eleven years of age, and were primarily male caucasian. Since 1989, each sample member had been administered the WISC-R once; and , each sample member had been administered the WJTEA-R twice, with at least 12 months separating the two administrations . Results identified no relationship between WSIC-R subtest scaled score scatter and reading achievment gain on the WJTEA-R. A positive correlation was identified be tween intelligence level and academic gains in reading. Important ancillary correlations of significance identified for all subjects included a negative relationship be tween the variable Age and the variables Intelligence , Academic gain, and the WISC-R FD factor . When intelligence was held to within average parameters significant correlations were identified between the variable Achievement and the variables Age and Time (negative), and with the WISC-R FD and VC factors (positive) . Multiple regression analyses indicated the FD factor best able to predict academic gain for this group. It is probable, that in the identification of learning disabled students, that the identification of processing disorders (as with previously sought patterns) is not viable. It may be that the only key characteristics are intellectual level and severe discrepancy.

The Wide Range Assessment of Memory and Learning (WRAML) is a relatively new instrument used in the assessment of memory in children. The purpose of this study was to examine the validity of the WRAML by comparing the performance of children on both the WRAML and the Woodcock-Johnson Tests of Cognitive Ability- Revised (WJTCA-R). Subjects for the study were children in treatment for a brain tumor at a regional children's medical center. Fifty children participated in the study ranging from ages 6 to 17. A multiple regression analysis was conducted to determine which of four selected clusters from the WJTCA-R would have the highest correlation with the Verbal Memory Index (VERI) from the WRAML. The Short-Term Memory (GSM) cluster had the highest correlation ( r = .82) as predicted. A Pearson's product-moment correlational analysis was conducted between the Visual Processing (GV) cluster from the WJTCA-R and the Visual Memory Index (VISI) from the WRAML. GV was found to have a high positive correlation ( r = .63) with VISI. A similar analysis was conducted between the Long-Term Retrieval (GLR) cluster from the WJTCA-R and the Learning Index (LRNI) from the WRAML. GLR was found to have a high positive correlation ( r = .81) with LRNI. Finally, a correlational analysis was conducted between the Broad Cognitive Ability (BCA) scale from the WJTCA-R and the General Memory Index (GENI) from the WRAML. A high positive correlation ( r = .87) was found between these most global measures from the two batteries. The observed correlation between BCA and GENI was much higher than anticipated. The author concluded that neurological impairment had affected subject memory and intellectual functioning in similar ways. The results do not generalize to children who have not had similar decrements in cognitive functioning. Future research should establish a baseline correlation between the two instruments with a non-impaired population.

Magister Artium - MA / In the majority of the schools in South Africa (SA), learners commence education in English. This English milieu poses a considerable challenge for English second-language speakers. In an attempt to bridge the gap between English as the main medium of instruction and the nine indigenous languages of the country and assist with the implementation of mother-tongue based bilingual education, this study focuses on the cross-validation of a monolingual English test used in the assessment of multilingual or bilingual learners in the South African context. This test, namely the Woodcock Muñoz Language Survey (WMLS), is extensively used in the United States in Additive Bilingual Education in the country. The present study is a substudy of a broader study, in which the original WMLS (American-English version) was adapted into SA English and Xhosa. For this specific sub-study, the researcher was interested in investigating the scalar equivalence of the adapted English version of the Verbal Analogies (VA) subscale of the WMLS across English first-language speakers and Xhosa first-language speakers. This was achieved by utilising differential item functioning (DIF) and construct bias statistical techniques. The Mantel-Haenszel DIF detection method was employed to detect DIF, while construct equivalence was examined by means of exploratory factor analysis (EFA) utilising an a priori two-factor structure. The Tucker's phi coefficient was used to assess the congruence of the construct across the two language groups / South Africa

Magister Artium (Psychology) - MA(Psych) / The fall of apartheid and the rise of democracy have brought assessment issues in multicultural societies to the forefront in South Africa. The rise of multicultural assessment demands the development of tests that are culturally relevant to enhance fair testing practices, and issues of bias and equivalence of tests become increasingly important. This study forms part of a larger project titled the Additive Bilingual Education Project (ABLE). The Woodcock Munoz Language Survey (WMLS) was specifically selected to evaluate the language aims in the project, and was adapted from English to isiXhosa. Previous research has indicated that one of the scales in the adapted isiXhosa version of the WMLS, namely the Picture Vocabulary Scale (PV), displays some item bias, or differential item functioning (DIF), across rural and urban isiXhosa learners. Research has also indicated that differences in dialects can have an impact on test takers’ scores. It is therefore essential to explore the structural equivalence of the adapted isiXhosa version of the WMLS on the PV scale across rural and urban isiXhosa learners, and to ascertain whether DIF is affecting the extent to which the same construct is measured across both groups. The results contribute to establishing the scalar equivalence of the adapted isiXhosa version of the WMLS across rural and urban isiXhosa-speaking learners. Secondary Data Analysis (SDA) was employed because this allowed the researcher to re-analyse the existing data in order to further evaluate construct equivalence. The sample of the larger study consisted of 260 learners, both male and female, selected from a population of Grade 6 and 7 learners attending schools in the Eastern Cape. The data was analysed by using the statistical programme Comprehensive Exploratory Factor Analysis (CEFA) and the Statistical Package for Social Sciences (SPSS). Exploratory factor analysis and the Tucker’s phi coefficient were used. The results indicated distinct factor loadings for both groups, but slight differences were observed which raised concerns about construct equivalence. Scatter plots were employed to investigate further, which also gave cause for concern. It was therefore concluded that construct equivalence was only partially attained. In addition, the Cronbach’s Alpha per factor was calculated, showing that internal consistency was displayed only for Factor 1 and not for Factor 2 for the rural group, or both factors for the urban group. Scalar equivalence across the two groups must therefore be explored further.
