Gender bias in IQ-discrepancy and post-discrepancy definitions of reading disability

The present study investigated the hypothesis that the higher prevalence of reading disability (RD) often observed among boys is partly an artifact of gender bias in the prediction of reading from IQ. The relevant regression statistics derived from a sample of more than 900 children revealed a statistically significant intercept bias. Predicted reading scores for boys were systematically overestimated, thereby inflating IQ-reading discrepancies; the converse was found for girls. When defined separately for girls and boys, severe underachievement in reading was found to be equally prevalent in both genders and, furthermore, was associated with qualitatively and quantitatively similar patterns of deficits. Because the bias arose from general differences between boys and girls in reading score distributions (a lower mean and greater variance for boys) rather than from differences in IQ scores, gender bias poses a potential threat not only to traditional IQ-discrepancy definitions but also to post-discrepancy definitions that are based solely on reading score cutoffs. Future classification criteria for RD need to take heed of the possibility that when the distributions of reading scores for boys and girls are not identical, performance cutoffs designating low achievement that are based on data pooled from both genders are likely to result in the overidentification of boys with RD and the underidentification of girls with RD.

Museums and Indigenous People in Australia: A Review of Previous Possessions,New Obligations: Policies for Museums in Australia and Aboriginal and Torres Strait Islander Peoples

Previous Possessions, New Obligations was launched by Museums Australia Inc. in 1993, the International Year for the World's Indigenous People, as a policy framework to guide the development of relationships between museums in Australia and Indigenous Australians. The policy was based on consultation with Indigenous people to develop protocols, policies and procedures for more sensitive collection management and for including Indigenous people in research and public programs; and to address issues of governance. It expressed the values that would underpin new relationships between museums in Australia and Indigenous Australians. An evaluation of the policy was conducted in 2000 in a collaboration between the Australian Museum Audience Research Centre, Sydney, and Museums Australia Inc., Canberra. The evaluation found that the policy had substantially met its goals, particularly in establishing the primary rights of Indigenous people to control their cultural material in museum collections. However, a range of substantially new issues emerged which require new policy responses and initiatives.     

Students’ Reflections on Implementation of Group Investigation in Korean Secondary Science Classrooms

Student reflective ideas were examined with respect to Group Investigation (GI), which was employed in 11^th grade Korean earth science classrooms. A modified GI method was implemented during the course of an action research effort consisting of two yearlong projects. Students’ writings, which had been produced twice a year, were analyzed to reveal their reflections concerning the GI method. The students were positive about how GI altered the ways their learning occurred in the classrooms. They also reported several positive learning outcomes resulting from the GI implementation. However, there were some students who considered the GI method inappropriate for them. At times, students had difficulties and experienced problems arising from implementing GI. Implications for use of cooperative inquiry learning methods in science classrooms are elaborated on and discussed.     

Longitudinal outcome effects of non-at-risk and at-risk transition first-grade samples: A follow-up study and further analysis

Fourth-grade follow-up achievement outcome data of placed and nonplaced transition extra-year school readiness samples indicate a nonsignificant standardized score difference, as noted in the second-grade findings. New analysis of correlation data indicates that within-sample age distribution shows a positive correlation with standardized achievement test scores in a study sample of non-at-risk students nonretained or recommended for retention. This age-achievement correlation is strong in kindergarten, with decreased effects by second and fourth grade. Four study samples of at-risk students (students retained in a transition extra-year school readiness program, students recommended and eligible for such placement but not placed, students retained in kindergarten through second grade, and students held out of school prior to kindergarten) reflect moderate inverse (negative) correlations between age and achievement test scores, with increasing inverse effects in fourth grade. Effect analysis and implications are discussed. © 1996 John Wiley & Sons, Inc.     

The influence of reputation information on the assessment of undergraduate student work

The present study employed an experimental design to examine the influence of knowledge of a student’s previous performance and the general quality of their writing style on the assessment of undergraduate student work. Fifteen sport and exercise physiology academics were asked to mark and give feedback on two final year undergraduate student essays. The first student essay that participants marked was a control essay. The second essay was the target essay. Participants read one of three student reputation profiles (positive, negative or neutral) prior to marking this essay. Kruskal–Wallis tests for difference indicated that the marks awarded to each essay did not significantly differ between the three student reputation conditions. Thematic analysis of the target essay also revealed no apparent differences in the way in which feedback was presented across the three student reputation profiles. It was therefore concluded that non-anonymous marking did not induce marker bias in this instance.     

Using the newspaper to support children's emerging literacy

Young children's literacy development involves emerging knowledge, skills, and attitudes about both written and oral language. However, until relatively recent years, children's oral language development has received the lion's share of attention in most early childhood programs. What young children know about written language and their natural ability to learn about writing and reading have been underestimated and misinterpreted and so have received little developmentally appropriate support from early childhood program administrators, teachers, parents, and the public.June Rose Richie is Associate Professor of curriculum and instruction, while Janet E. Foster is Assistant Professor and John M. Johnston is Professor of early childhood education, at Memphis State University, Memphis, TN.     

Human causality judgments and response rates on DRL and DRH schedules of reinforcement

The effect of various relationships between a response (an investment made in the context of a game) and an outcome (a return on the investment) on judgments of the causal effectiveness of the response was examined. In Experiment 1, response rates and causal judgments were higher for a differential-reinforcement-of-high-rate (DRH) schedule relative to a variable-ratio (VR) schedule with the same probability of outcome following a response. Response rates were also higher for a DRH than for a variable-interval schedule matched for reinforcement rate. In Experiment 2, response rates and causal judgments were lower for a differential-reinforcement-of-low-rate schedule relative to a VR schedule with the same probability of outcome following a response. These results corroborate the view that schedules are a determinant of both response rates and causal judgments, and that few current theories of causal judgment explicitly predict this pattern of results.
