WISC-R factor structures among White,Mexican American,and African American children: A research note

The factor structure for the Wechsler Intelligence Scale for Children-Revised (WISC-R) was investigated for White (n = 183), Mexican American (n = 129), and African American (n = 139) nonreferred school-age children (6.8 to 14.6 years) of low-to middle-class socioeconomic background. Exploratory and confirmatory factor analyses were performed. The WISC-R factor structure model tested was Kaufman's (1975) three-factor solution that consisted of Verbal Comprehension (VC, Factor 1), Perceptual Organization (PO, Factor 2), and Freedom from Distractibility (FD, Factor 3). The results of the exploratory analyses showed Kaufman's three-factor solution for the three ethnic groups, but the order of Factor 2 and Factor 3 was reversed for the Mexican American and African American samples—thus raising questions about the comparability of the WISC-R factor structure across groups. The confirmatory analyses, which used the orthogonal nested factors approach by Gustafsson and Balke (1993), resulted in a model (for each of the ethnic groups) in which a G factor explained most of the variance (followed by the nested first-order factors—VC, PO, and FD). The results of the confirmatory analyses provide some support for David Wechsler's (1974) original intentions that the WISC-R structure is best described as having a general, or global, factor. © 1997 John Wiley & Sons, Inc.     

Evidence of bias in predictive validity on the Kaufman assessment battery for children in samples of Anglo and Mexican American children

Possible bias in the differential predictive validity of the Kaufman Assessment Battery (K-ABC) was investigated with 76 Anglo and 90 Mexican American fifth- and sixth-grade boys and girls. All children were English-speaking and from similar socioeconomic backgrounds. The criterion variable was the Comprehensive Tests of Basic Skills (CTBS; Language, Reading, Mathematics, and Total Scores). Several statistical techniques were used to investigate test bias (examination of predictive validity coefficients; two methods of examining homogeneity of slopes of the regression lines). The results showed considerable evidence of bias in differential predictive validity, indicating that the global cognitive score of the K-ABC (the Mental Processing Composite) was less effective in predicting CTBS scores for the Mexican American group than for the Anglo group.     

Selecting gifted children with the Slosson Intelligence Test: 1981 vs. 1961 norms

The Slosson Intelligence Test (SIT) for Children and Adults protocols for 683 gifted students ranging in age from 6 to 12 years were scored using both 1961 and 1981 norms. The average 1981 norm score was 5.17 points lower than the 1961 norm score. The differences increase with the age of the child. Implications for using the SIT for selecting gifted children are discussed.     

Students with disabilities and clinical placement: understanding the perspective of healthcare organisations

The Australian Disability Discrimination Act (1992) has challenged higher education to meet the increasing needs of students with different abilities. This may be more so in programmes that have practice components where students must demonstrate competency, regardless of their situation. This qualitative exploratory study undertaken at the University of South Australia (UniSA) investigated host healthcare organisations’ perspectives on providing clinical practice placements and supporting Bachelor of Nursing (BN) students with physical disabilities through their practice components. An advisory group consisting of the university’s legal officer, disability services representative, programme directors and other academics from the BN monitored the project. Directors of nursing from 50 randomly selected South Australian metropolitan and rural healthcare organisations that host student placements nominated a representative from their organisations to participate in a series of focus groups. Focus group discussion was guided by open questions developed from relevant literature, research team deliberations, advisory group recommendations and the previous focus group discussions. Data analysis consisted of manually identifying themes from each stage of the process, and the congregate data. The findings were bridging the reality gap through joint commitment, the right of disclosure versus confidentiality and proactivity through collaboration and communication.     

Children,families, and feminism: Perspectives on teaching

Feminist theorists are raising questions about assumptions still common in the fields of family and child development which are relevant to early childhood educators. This article discusses why content and pedagogy work together in feminist classrooms and reviews research on the stages that many students and instructors move through as they learn about ways in which women continue to struggle for equal status in modern American society.     

Peer Networking as a Dynamic Approach to Supporting New Faculty

This article presents a dynamic method of supporting new faculty through a peer support group led by a facilitator. Group members participate in ongoing self-assessment, individualized goal setting, and activities that reflect the changing needs of the group. We explain the history and activities of the group and also the benefits for institutions considering developing a support mechanism for new faculty.     

Emergence of graphic symbol functioning and the question of domain specificity: a longitudinal training study

The impact of social scaffolding on the emergence of graphic symbol functioning was explored in a longitudinal training study. Links among graphic, language, and play domains in symbolic development were also investigated. The symbolic functioning of 16 children, who were 28 months at the outset of the study, was assessed in comprehension and production tasks across the three domains at monthly intervals from 28 to 36 months, and again at 42 months. Training was delivered in between monthly assessments during weekly visits. Half of the children received training, which consisted of the experimenter drawing common objects and highlighting the relation between pictures and their referents, for 16 consecutive weeks early in the study (early training, ET). The remaining half received a placebo version of training for these 16 weeks, followed by actual training for 4 weeks in the fifth month (late training, LT). After the first 4 months of training the ET group was found to have accelerated comprehension and production of graphic symbols relative to the LT group. After the fifth month, the LT group reached the same level of graphic symbol performance as the ET group. There were strong positive correlations found among graphic symbol functioning and language and play, and between play and language. These findings support the view that graphic symbolic development can be influenced by cultural scaffolding, that more extensive training is needed early rather than later in development, and that interrelationships exist among symbolic domains.     

The informationist: building evidence for an emerging health profession

Background:

To encourage evidence-based practice, an Annals of Internal Medicine editorial called for a new professional on clinical teams: an informationist trained in science or medicine as well as information science.

Objectives:

The study explored the effects of informationists on information behaviors of clinical research teams, specifically, frequency of seeking information for clinical or research decisions, range of resources consulted, perceptions about access to information, confidence in adequacy of literature searches, and effects on decision making and practice. It also explored perceptions about training and experience needed for successful informationists.

Methods:

Exploratory focus groups and key interviews were followed by baseline and follow-up surveys conducted with researchers and clinicians receiving the service. Survey data were analyzed with Pearson''s chi-square or Fisher''s exact test.

Results:

Comparing 2006 to 2004 survey responses, the researchers found that study participants reported: seeking answers to questions more frequently, spending more time seeking or using information, believing time was less of an obstacle to finding or using information, using more information resources, and feeling greater satisfaction with their ability to find answers. Participants'' opinions on informationists'' qualifications evolved to include both subject knowledge and information searching expertise.

Conclusion:

Over time, clinical research teams with informationists demonstrated changes in their information behaviors, and they valued an informationist''s subject matter expertise more.

Highlights

• Informationist involvement in traditional team activities—going on rounds and searching and critically evaluating the literature—increased over time.
• As the relationship between a clinical team and informationist developed, activities expanded to include projects such as development of wikis, databases, and websites.
• Clinical teams came to view subject knowledge as key to an informationist''s preparation; however, their expertise as information scientists was valued most highly.
• “Initiative,” approaching research staff in their workplace, was the one personal trait focus group participants agreed on as most desirable for an informationist.
• When first introduced to the concept, researchers cited customization of services to team needs as a major benefit.

Implications

• To assure a successful informationist program, libraries must be prepared to commit time and money.
• Whether informationists or not, librarians should be prepared to support users'' increased need for genetics and molecular biology information.

     

The Importance of Intentional Socialization Among Children in Small Groups: A Conversation with Loris Malaguzzi

Loris Malaguzzi, founder and guide for 50 years to the schools of young children in Reggio Emilia, Italy, passed away in January 1994. In this interview, conducted in 1990, Malaguzzi speaks directly to early childhood educators in the United States. He blends theory and practice as he clarifies the theoretical base of the Reggio schools and discusses pedagogical implications for early childhood practitioners who want to work from a deep understanding of children's thinking and questions.
