Factors influencing the identification of black and white students with learning disabilities     

J McLeskey  N L Waldron  S A Wornhoff 《Journal of learning disabilities》1990,23(6):362-366

This study examined the differential influence of an IQ cutoff and standard score or regression-based method for determining a severe discrepancy as eligibility criteria for the identification of black and white students with learning disabilities. Subjects were 218 white and 132 black students referred for possible learning disability services. The results of the study demonstrated that the use of a standard score method for determining a severe discrepancy and the use of an IQ cutoff above the range for mental retardation resulted in the disproportionate underrepresentation of black students meeting eligibility criteria. In contrast, when a regression-based method to determine a severe discrepancy was used, along with the absence of an IQ cutoff, no differences were discerned between the two groups. The implications of these findings for current practice are discussed.  相似文献   

Willing to play the game: How at‐risk students persist in school     

Kimberly Knesting  Nancy Waldron 《Psychology in the schools》2006,43(5):599-611

A qualitative case study of 17 high‐school students identified as at risk for dropping out, this research develops a grounded theory describing the process of students' persistence and the support they received from teachers and school administrators. Three interactive factors appear critical to persistence: (a) goal orientation—students' belief they will benefit from graduating, (b) willingness to play the game—students' willingness to follow school rules, and (c) meaningful connections—relationships with teachers who believed students could graduate and provided support and caring. All three factors were present for students who stayed through the school year whereas one or more was absent from the experiences of the students who left school before graduation. The research provides further support for the role of schools in supporting students' persistence and has implications for how schools support students who are struggling to stay in school. © 2006 Wiley Periodicals, Inc.

Small‐Sample Equating Using a Synthetic Linking Function     

Sooyeon Kim  Alina A. Von Davier  Shelby Haberman 《Journal of Educational Measurement》2008,45(4):325-342

This study addressed the sampling error and linking bias that occur with small samples in a nonequivalent groups anchor test design. We proposed a linking method called the synthetic function, which is a weighted average of the identity function and a traditional equating function (in this case, the chained linear equating function). Specifically, we compared the synthetic, identity, and chained linear functions for various‐sized samples from two types of national assessments. One design used a highly reliable test and an external anchor, and the other used a relatively low‐reliability test and an internal anchor. The results from each of these methods were compared to the criterion equating function derived from the total samples with respect to linking bias and error. The study indicated that the synthetic functions might be a better choice than the chained linear equating method when samples are not large and, as a result, unrepresentative.  相似文献   

An analysis of WISC-R factors for gifted students with learning disabilities   总被引：1，自引：0，他引：1  

K A Waldron  D G Saphire 《Journal of learning disabilities》1990,23(8):491-498

Intellectual patterns of gifted students with learning disabilities were studied to determine cognitive factors characterizing these children. Twenty-four gifted children with learning disabilities (LD) and a control group of nondisabled gifted children were administered the Wechsler Intelligence Scale for Children-Revised (WISC-R) (Wechsler, 1974). While differences between the two groups on individual subtests were examined, a comparison of broader factors was emphasized in discovering cognitive patterns that might suggest effective intervention. Experimental and control performances were compared on 14 factor scores, using cognitive classification systems of Bannatyne (1971), Kaufman (1975), Rapaport, Gill, and Schafer (1946), and Wechsler (1974). Gifted students with LD were more reliant on verbal conceptualization and reasoning than the control students. They also demonstrated deficiencies in short-term auditory memory and sound discrimination. The gifted group with LD exhibited the Organic Brain Syndrome factor (Wechsler, 1974) to a significantly greater extent than did the control group.  相似文献

On understanding variability in data: a study of graph interpretation in an advanced experimental biology laboratory     

Wolff-Michael Roth  Shelby Temple 《Educational Studies in Mathematics》2014,86(3):359-376

Data analysis is constitutive of the discovery sciences. Few studies in mathematics education, however, investigate how people deal with (statistical) variability and statistical variance in the data to be interpreted. And even fewer, if any, focus on the uncertainties with which scientists wrestle before they are confident in the data they produce. The purpose of this study is to exhibit the work of coping with variability in one advanced research laboratory, as exemplified in a typical data analysis session. The study shows that when the scientists are confronted with novel data, their understanding of the variability does not arise in straightforward fashion, and a lot of normally invisible (interactional) work is required to constitute understanding. Tentative conclusions are provided for the implication to mathematics education.  相似文献

Influence of Involvement in the Girls on Track Program on Early Adolescent Girls' Self-Perceptions     

Jennifer J. Waldron 《Research quarterly for exercise and sport》2013,84(5):520-530

The Model of Competence Motivation (Harter, 1978) highlights how self-perceptions are influenced by individual and socialization factors. Using this model, the present study investigated, quantitatively with a pretest and posttest design (N = 34) and qualitatively via individual interviews (N = 8), how involvement in the Girls on Track program (GOT) influenced the perceived competence and self-worth of sixth-grade girls. GOT is a program that uses training for a 5-km race as a means to teach life skills. The self-perceptions of the participants showed increasing trends from pre- to posttest. Interviewed girls discussed their acquisition of interpersonal skills and of positive feelings about themselves. The discussion emphasizes how program involvement can influence the development of self-perceptions in early adolescent girls.  相似文献   

Case Study Research: A Valuable Learning Tool for Performance Improvement Professionals     

John R. Turner  Shelby Danks 《Performance Improvement》2014,53(4):24-31

Although it is sometimes recommended that performance improvement (PI) professionals include experimental research designs in their repertoire of PI tools and methods, it has been long understood that experimental designs can be difficult to implement due to impediments resulting from the complex nature of the organizational settings. However, the utilization of case study research has proven to be an effective alternative to aid in the identification of strengths and opportunities for the improvement of organizational procedures, policies, processes, or programs. Case study research helps managers and practitioners make sense of real world problems. This article presents a summary of steps in the design of case study research and provides examples of how these methods have been used within organizational settings. Implications for PI practitioners are provided.  相似文献   

Preparing Reflective Community College Leaders in a Graduate Leadership Course     

Leila González Sullivan  Shelby Palmer 《Community College Journal of Research & Practice》2013,37(6):512-522

This study measured the knowledge construction and reflection that occurred in a doctoral course designed to introduce major leadership theories and encourage reflection as a community college leadership practice. At each session, students completed forms reporting new learning and insights they experienced, as well as responding to reflection catalysts. Three themes emerged from the data: reflection on previous internal perspectives about leadership, critical review of personal and theoretical constructs, and embracing relational leadership. By the end of the course, students acknowledged the value of collaborative learning, and demonstrated changed perspectives regarding leadership practices, together with increased habits of reflection. Implications for graduate-level instruction and further research are proposed, based on the conclusion that the New Learning process is valuable for certain types of classes, is beneficial for professional development, and conforms to principles of transformative learning among adults.  相似文献
