Longitudinal course of rapid naming in disabled and nondisabled readers

The Rapid Automatized Naming Test (Denckla and Rudel 1974) was studied cross-sectionally in an sample of kindergartners (n=342) at-risk for reading disability (Study 1), and longitudinally in an n=160 epidemiological normal sample of children tested in first, third, fifth, and eighth grades (Study 2). Study 1 showed faster absolute naming speeds for those with near perfect untimed alphabet recitation, but the stronger and more orderly relation (at r=.31, p<.0001) was between three levels of alphabet recitation accuracy and the relative number/letter naming speed advantage (ratio of mean number/letter naming speed minus mean color/object naming speed over mean color/object naming speed). In Study 2, the number/letter advantage was already strongly present by first grade, and did not increase significantly thereafter, but absolute naming times improved steadily across grades in an exponential decay function. In this sample, the relative number/letter advantage was not related to reading level. However, the absolute color/object naming speed was strongly related to reading level and vocabulary across grades. Norms for the Rapid Automatized Naming Test based on the epidemiological normal sample tested in Grades 1, 3, 5, and 8 are presented in the appendix.     

“Fixing” the “Facts”: flexible learning as policy invention

This article examines the contemporary move within the Australian university context towards flexible learning. Drawing on the notions of policy as text and discourse, it is suggested that policies seek to provide authoritative meanings for practices they promote — to fix the facts about which they speak. The article explores the emergence of discourses of flexible learning as effects of policy texts and changes within the social formation. These discourses resonate with those already operating within the social formation, and in this may have effects other than those immediately apparent. An initial analysis of Australian higher education policy texts indicates a contemporary diversification of the use of the metaphor of flexibility as a discursive strategy through which mechanisms of governance can be intensified.     

The Emergence of Cognitive Maps for Spatial Navigation in 7- to 10-Year-Old Children

Although much is known about adults’ ability to orient by means of cognitive maps (mental representations of the environment), it is less clear when this important ability emerges in development. In the present study, 97 seven- to 10-year-olds and 26 adults played a video game designed to investigate the ability to orient using cognitive maps. The game required participants to reach target locations as quickly as possible, necessitating the identification and use of novel shortcuts. Seven- and 8-year-olds were less effective than older children and adults in using shortcuts. These findings provide clear evidence of a distinct developmental change around 9 years of age when children begin to proficiently orient and navigate using cognitive maps.     

Comparing the Accuracy of Student Growth Measures

Testing programs are often interested in using a student growth measure. This article presents analytic derivations of the accuracy of common student growth measures on both the raw scale of the test and the percentile rank scale in terms of the proportional reduction in mean squared error and the squared correlation between the estimator and target. The study contrasts the accuracy of the growth measures against that of current status measures—current test scores and their percentile ranks. Key findings include the extent that status measures are more accurate than any of the growth measures and that alternative methods to estimate growth could be more accurate than the currently used methods. Our findings highlight the importance for evaluating the statistical properties of growth measures along with other concerns for states that are debating the reporting of growth. Our results also point out that assessing the accuracy of growth measures requires the specification of quantities of interest in terms of latent achievement rather than observed test scores, which is common practice for developing status measures but essentially never done by testing programs for growth measures.     

What Kind of a Girl Does Science? The Construction of School Science Identities

A view of science as a culturally‐mediated way of thinking and knowing suggests that learning can be defined as engagement with scientific practices. How students engage in school science is influenced by whether and how students view themselves and whether or not they are the kind of person who engages in science. It is therefore crucial to understand students' identities and how they do or do not overlap with school science identities. In this paper, we describe four middle school African American girls' engagement with science. They were selected in the 7th grade because they expressed a fondness for science in school or because they had science‐related hobbies outside of school. The data were collected from the following sources: interviews of students, their parents and their teachers; observations in science classes; journal writing; and focus groups. These girls' stories provide us with a better understanding of the variety of ways girls choose to engage in science and how this engagement is shaped by their views of what kind of girl they are. © 2000 John Wiley & Sons, Inc.

Culture wars in the classroom: Prospective teachers question science

Does studying about the nature(s) of science contribute to a prospective teachers' effectiveness as a science teacher? This research grew out of a course created by a science educator and historian of science who believed prospective teachers needed more complex understandings of the cultural wars surrounding science. The research team consisted of five prospective teachers who participated in the course as well as the two instructors. This paper describes the experience of participating in the course from both perspectives. We argue that studying the cultural wars over science contributes to prospective teachers' professional growth as much because the course elicits tacit beliefs about school science as it introduces more complex understandings of science. We found that prospective teachers' tacit beliefs about school science were their greatest barrier to developing more complex understandings about the nature(s) of science. We contend that willingness to grapple with complexity and developing a professional identity by locating oneself in the conversations about the nature(s) of science are better criteria for determining the professional growth of prospective teachers than knowledge measures. Finally, we argue that prospective teachers should be viewed as professionals who are responsible for finding their own voice, making their own decisions, and considering the consequences of their beliefs on their practice. This study raises questions critical to teacher education programs for prospective teachers and teacher‐educators alike. © 2000 John Wiley & Sons, Inc. J Res Sci Teach 37: 895–915, 2000     

Gender differences in preschool children’s recall of competitive and noncompetitive computer mathematics games

This study investigated whether competitive and noncompetitive educational mathematics computer games influence four‐ to seven‐year‐old boys’ and girls’ recall of game‐playing experience. A qualitative analysis was performed to investigate what preschool children may have learned through their selective recall of game‐playing experience. A difference emerged in six‐ to seven‐year‐old boys’ and girls’ recall after playing a competitive computer mathematics game, such that boys tended to first recall the consequence of ‘winning and losing’ whereas girls of the same age focused on ‘friendship among animated characters’ in the game. Thus, the qualitative results suggest the possibility that selective attention or selective recall might be partially influenced by gender schemas. Based on the recall sequences, educational noncompetitive computer mathematics games may lead to a better learning outcome for older boys.     

Using scenarios to identify and manage allocation decision risks

This paper employs the solver function in Microsoft Excel? to make a ‘what-if' analysis of library materials budgetary allocation decisions. Two sets of allocation constraints are presented and used to describe two different theoretical scenarios: (1) a slight materials budget increase and (2) a significant materials budget decrease. In each scenario, the associated allocation ‘parity' risks are identified using solver and the outcomes of different risk management strategies are considered. Sensitivity to context requires different risk management solutions to minimize conflicts between stakeholders with competing interests. By pre-managing allocation risks, the decisions allow library materials budgets to be optimized.
