Interocular transfer in pigeons of color discrimination but not motor response training

Adult pigeons with one eye covered were trained to peck a response key using grain as a reinforcer. In subsequent tests, with the trained eye covered and the control eye open, the birds failed to peck the key. The subjects were then divided into two groups for a second experiment. The first group was trained on a single-key, peck/no-peck color discrimination task with the original control eye covered. When tested for interocular transfer of discrimination performance, these birds failed to respond at all. They were then trained to peck a blank response key with the training eye covered and the control eye open. Control-eye tests after this motor response training resulted in excellent transfer of color discrimination performance. The second group of subjects was trained to peck a blank key with first one eye covered and then the other, before monocular discrimination training was begun. These birds showed excellent transfer of discrimination performance during control-eye tests. These results show that, at least in the operant paradigm, motor response training does not transfer interocularly and this lack of transfer may interfere with transfer of discrimination performance.     

Potenziale schulstatistischer Individualdaten für die Bildungsforschung und Bildungspolitik – Das Beispiel Bremen

Education policy and educational practitioners have increased their demand for evidence-based knowledge. In 2003, the Standing Conference of the Ministers of Education and Cultural Affairs (KMK) decided to establish a core dataset for individual-level administrative school statistics, the ?Kerndatensatz für schulstatistische Individualdaten“, to close the gaps in education statistics and to support evidence-based policy. In the federal state of Bremen, individual-level student data has been collected since 1997/98. These data are of great value for educational planning and policy, educational reporting, as well as educational research, as the analysis of individual educational trajectories depends on the availability of individual-level longitudinal data. Using the Bremen data, this paper demonstrates that highly relevant issues regarding the education system can indeed be analyzed with individual-level student data. Examples include: the effects of age at school entry, educational trajectories and graduation certificates. The results show that demographic information and critical events during early years of education are good predictors for educational success. These findings highlight the potential for student-level data in establishing education policy.     

Bias and Bias Correction Method for Nonproportional Abilities Requirement (NPAR) Tests

Test items must often be broad in scope to be ecologically valid. It is therefore almost inevitable that secondary dimensions are introduced into a test during test development. A cognitive test may require one or more abilities besides the primary ability to correctly respond to an item, in which case a unidimensional test score overestimates the primary ability and creates interpretability problems. In this article, we demonstrate the nonproportional abilities requirement, a phenomenon with which secondary abilities are more required for difficult items. A novel and practical method for correcting bias in the primary ability is proposed and illustrated using a real data set from an international assessment. Simulation data are also used to evaluate the performance of the method.     

Consulting stakeholders in the development of an environmental policy implementation plan: a Delphi study at Dalhousie University

This paper reports on a Delphi Study undertaken at Dalhousie University in which a multi‐stakeholder panel was consulted in order to generate ideas that could be incorporated into an Implementation Plan for the University Environmental Policy (UEP). The objectives of the study were twofold. First, the study endeavored to develop ideas as to the most desirable and feasible ways in which to incorporate the UEP into the activities and structure of the university. Second, the study sought to assess the applicability of the Delphi Technique for consulting with stakeholders in the development of an implementation plan. The final analyses confirm the literature on the challenges, barriers and opportunities encountered for institutional environmental change in higher education. The study also confirms the findings of existing research that promotes the Delphi Technique as an excellent tool to inform the creation of educational and social policy. Specifically, this study illustrates the benefits of applying the Policy Delphi Technique to the development of an Environmental Policy Implementation Plan in higher education.     

Bright and Beautiful: High achieving girls,ambivalent femininities,and the feminization of success in the primary school

This paper refocuses attention on and problematizes girls’ experiences of school achievement and the construction of schoolgirl femininities. In particular, it centres on the relatively neglected experiences and identity work of high achieving primary school girls. Drawing upon ethnographic data (observations, interviews, and pupil diaries) from a broader study of girls’ and boys’ perceptions and experiences of schoolwork and achievement from two contrasting primary schools in a city in South Wales (UK), the paper will explore the gendered subjectivities of high achieving girls from diverse social and cultural backgrounds. Three narrative case studies are re-presented and analysed to explore the feminization of success and thus the tensions and contradictions as girls negotiate the pushes and pulls to be both “bright” (i.e. succeeding academically) and “beautiful” (succeeding in “doing girl”). Of key interest are the possibilities, costs, and consequences of girls producing ambivalent femininities and the rearticulation and transgression of normative ways of “doing clever” and “doing girl” in 21st century primary schools.     

Understanding pedagogical design capacity through teachers’ narratives

Teachers need to develop the ability to adapt curriculum materials. Two elementary teachers, Maggie and Catie, were asked to write narratives about their use of and changes to particular reform-oriented science lesson plans. Maggie drew on her knowledge of and experiences with students, as well as other knowledge, experiences, and resources, to make productive changes to account for her students’ prior knowledge and abilities. Catie based her curricular adaptations on her learning goals—but these were not aligned with the learning goals of the curriculum materials. The paper discusses implications for teacher education, professional development, and educative curriculum materials.     

Parental Involvement Moderates Etiological Influences on Attention Deficit Hyperactivity Disorder Behaviors in Child Twins

Although few would now contest the presence of Gene × Environment (G × E) effects in the development of child psychopathology, it remains unclear how these effects manifest themselves. Alternative G × E models have been proposed (i.e., diathesis–stress, differential susceptibility, bioecological), each of which has notably different implications for etiology. Child twin studies present a powerful tool for discriminating between these models. The current study examined whether and how parental involvement moderated etiological influences on attention deficit hyperactivity disorder (ADHD) within 500 twin pairs aged 6–11 years. Results indicated moderation of genetic and nonshared environmental contributions to ADHD by parental involvement, and moreover, suggested both differential susceptibility and bioecological models of G × E. Results highlight the utility of child twin samples in testing different manifestations of G × E effects.     

Elementary and Middle School Students’ Conceptions of Knowledge,Information, and Truth

Although the study of epistemic beliefs has received growing interest in the past decades, this research tends to focus on high school and undergraduate students, and does not address beliefs about information and truth, concepts that have been regarded as critical for learners in 21st-century educational contexts. In this study, the authors examined 87 elementary and middle school students’ beliefs about the definitions of and relations among knowledge, information, and truth through the use of a graphical and justification task, and addressed the consistency of beliefs across contexts and domains. Results indicated that students tended to regard knowledge, information, and truth as interrelated, and the majority of students described their beliefs as consistent across contexts and domains.     

A cross-cultural comparison of cognitive and affective mediators in the relationship between media use and body image disturbance: focusing on US and Korean women

This study examined whether the relationship between cumulative thin-ideal media and body image disturbance is mediated by (1) cognitive variables, including beliefs about normative thinness and thinness prevalence and (2) affective variables, including dejection and agitation. Also, this study tested whether mediating effects would be different across cultures. Results revealed that perception about normative thinness mediated the relationship between thin–ideal media use and body image disturbance among both US and Korean participants and the effect was stronger for Korean participants. Thinness prevalence estimation did not mediate thin-ideal media use and body image disturbance in either Korean or US participants. Dejection was a statistically significant mediator for the relationship between thin-ideal media use and body image disturbance for both Korean and US participants, but no cultural differences were found. Agitation was also a statistically significant mediator for thin-ideal media use and body image disturbance, but only for Korean participants. Cultural differences in mediating effects were explained based on individualism and collectivism.
