The concurrent validity of the peabody individual achievement test and woodcock reading mastery tests among students with mild learning problems

Previous research has revealed moderate to high validity coefficients between the Peabody Individual Achievement Test and the Woodcock Reading Mastery Tests. However, the same research has indicated rather consistently that the latter instrument provides significantly lower means than do several screening tests currently being used in the field. This investigation replicated and extended previous research by comparing the two instruments across three grade clusters in order to determine whether the lower Woodcock scores are equally robust for each level. As in prior research, validity coefficients were moderate to high in magnitude. However, the differences between the means of two instruments were found to decrease in size from earlier to later grades. That is, seven of the eight significantly different means were found to occur in grades 1 through 4. Only one significant difference was found for grades 5 through 8. Discussion sought to explain the results in terms of the representativeness of the Woodcock norms and the novel method that Woodcock used to estimate sample means and standard deviations.     

Engaging Experts: Science-Policy Interactions and the Introduction of Congestion Charging in Stockholm

This article analyzes the conditions for mobilizing the science base for development of public policy. It does so by focusing upon the science-policy interface, specifically the processes of direct interaction between scientists and scientifically trained experts, on the one hand, and agents of policymaking organizations, on the other. The article defines two dimensions – cognitive distance and expert autonomy – which are argued to influence knowledge exchange, in such a way as to shape the outcome. A case study on the implementation of congestion charges in Stockholm, Sweden, illustrates how the proposed framework pinpoints three central issues for understanding these processes: (1) Differentiating the roles of, e.g., a science-based consultancy firm and an academic environment in policy formation; (2) Examining the fit between the organizational form of the science-policy interface and the intended goals; and (3) Increasing our understanding of when policymaker agents themselves need to develop scientific competence in order to interact effectively with scientific experts.     

Parents Influence the Visual Learning Environment Through Children's Manual Actions

The present research studied children in the second year of life (N = 29, M_age = 21.14 months, SD = 2.64 months) using experimental manipulations within and between subjects to show that responsive parental influence helps children have more frequent sustained object holds with fewer switches between objects compared to when parents are either not involved or over-involved. Regardless of parental involvement, sustained holds were visually rich, based on the size, centeredness, and dominance of the held object relative to other objects. These findings are important because they suggest not only that the child's body creates visually rich scenes across play contexts but also that a responsive parent can increase the frequency of these visually rich and informative moments.     

Unravelling the complexities of distance education student attrition

This paper reports on an investigation into the complexities of student attrition in a distance education course. Deep‐seated factors involved in the attrition process are disclosed as the particular qualitative research process that was employed mapped student responses through the course of interviews. These tabulations reveal interesting patterns of change as students volunteer explanations for their decisions.
