Social and Nonsocial Functions of Rostral Prefrontal Cortex: Implications for Education

ABSTRACT— In this article, we discuss the role of rostral prefrontal cortex (approximating Brodmann Area 10) in two domains relevant to education: executive function (particularly prospective memory, our ability to realize delayed intentions) and social cognition (particularly our ability to reflect on our own mental states and the mental states of others). We review evidence from neuropsychology and neuroimaging suggesting the involvement of rostral prefrontal cortex in these domains and discuss an overarching framework that seeks to characterize these functions in terms of attentional selection between perceptual and self-generated information. In addition, we present neuroimaging evidence in adults suggesting considerable functional specialization within this region. We conclude by discussing implications of these results for education and suggest directions for further research.     

Accelerating chronically unresponsive children to tier 3 instruction: what level of data is necessary to ensure selection accuracy?

Response-to-intervention (RTI) approaches to disability identification are meant to put an end to the so-called wait-to-fail requirement associated with IQ discrepancy. However, in an unfortunate irony, there is a group of children who wait to fail in RTI frameworks. That is, they must fail both general classroom instruction (Tier 1) and small-group intervention (Tier 2) before becoming eligible for the most intensive intervention (Tier 3). The purpose of this article was to determine how to predict accurately which at-risk children will be unresponsive to Tiers 1 and 2, thereby allowing unresponsive children to move directly from Tier 1 to Tier 3. As part of an efficacy study of a multitier RTI approach to prevention and identification of reading disabilities (RD), 129 first-grade children who were unresponsive to classroom reading instruction were randomly assigned to 14 weeks of small-group, Tier 2 intervention. Nonresponders to this instruction (n = 33) were identified using local norms on first-grade word identification fluency growth linked to a distal outcome of RD at the end of second grade. Logistic regression models were used to predict membership in responder and nonresponder groups. Predictors were entered as blocks of data from least to most difficult to obtain: universal screening data, Tier 1 response data, norm referenced tests, and Tier 2 response data. Tier 2 response data were not necessary to classify students as responders and nonresponders to Tier 2 instruction, suggesting that some children can be accurately identified as eligible for Tier 3 intervention using only Tier 1 data, thereby avoiding prolonged periods of failure to instruction.     

A Moderated Mediation Model: Racial Discrimination,Coping Strategies,and Racial Identity Among Black Adolescents

This study examined a moderated mediation model among 314 Black adolescents aged 13–18. The model included general coping strategies (e.g., active, distracting, avoidant, and support‐seeking strategies) as mediators and racial identity dimensions (racial centrality, private regard, public regard, minority, assimilationist, and humanist ideologies) as moderators of the relation between perceived racial discrimination and depressive symptoms. Moderated mediation examined if the relation between perceived racial discrimination and depressive symptoms varied by the mediators and moderators. Results revealed that avoidant coping strategies mediated the relation between perceptions of racial discrimination and depressive symptoms. The results indicated that avoidant coping strategies mediated the relation between perceived racial discrimination and depressive symptoms among youth with high levels of the minority/oppressive ideology.     

Jakob Leupold's Imaginary Automatic Anamorphic Devices of 1713

In 1713, the scientific instrument-maker Jakob Leupold published designs for three machines were the first attempt to design machinery with internal moving parts that replaced human agency in creating original images. This paper first analyzes his text and engravings in order to explain how he proposed to do this, given contemporary materials and command of physical forces. Next, it characterizes the devices as a transition from concepts of incision to concepts of mirroring, taken as models of the history of mechanical reproduction. And finally, Leupold’s replacement of the sighting grid with differential gears points to a set of problems appearing in contemporary philosophy represented in Rococo artistic production of this period as well. Taking the proposed devices in context, they help to theorize the complex notions of creative activity in Rococo visual culture. Taken as an episode in the history of communications, they instance the development of conceptions of personhood and of physical forces at stake in the invention of automated media.     

Students' Visualization of Metallic Bonding and the Malleability of Metals

This study investigated the mental representations of metallic bonding and the malleability of metals held by three male students aged 14–15 (Year 10) who were attending a Hong Kong school. One student was selected by their chemistry teacher as representing each of the highest, the medium, and the lowest level of attainment in chemistry in a school that admitted students of average general attainment. The students were interviewed and their understandings probed through their provision of drawings and their interpretation of the diagrams that had been previously used by their teacher. Dual coding theory was used to interpret the relative significance of visual and verbal input and the interaction between the two for their understanding. There was evidence that students relied on verbal recall in providing their initial understandings and showed an appreciation of the nature of the structural components of the electron-sea model of metallic bonding. However, they varied in terms of their appreciation of the electrostatic force which was responsible for the malleability of metals. The study suggests that a clearer understanding of the electrostatic force involved can be attained when students experience visual and verbal representations simultaneously, a conclusion supported by dual coding theory. Principles for good practice in using diagrams in teaching are discussed.     

Enigmas in School Science: students’ conceptions for scientifically associated words

Master's students were involved in the design, and later the administration, of a questionnaire for 500 junior secondary students in Botswana and Lesotho, to buildup a picture of student perceptions of science and technology. Responses to mainly open‐ended questions were categorised according to key phrases mentioned by the students. There was some confusion over the differences between science and technology, but they were overwhelmingly perceived as subjects appropriate to both sexes. Science and technology were seen in broad socio‐economic terms, enabling people to cope in the modern world, gain employment in both the formal and informal sectors, and contribute towards national development. Although science and technology were judged to have enhanced the quality of life, they had introduced conflicts into traditional beliefs and cultures, in part as a result of increasing female emancipation. The attitudes of the students towards the two subjects, and to the impact they have had on everyday life, were congruent with the philosophical aims of the science and technology syllabuses of both countries and with global initiatives such as Project 2000 +.     

An Intergenerational E-mail Pal Project on Attitudes of College Students Toward Older Adults

Intergenerational interactions have demonstrated some success at improving attitudes of college students toward older adults. This quasiexperimental study involved undergraduate college students paired with older adults for a six-week e-mail exchange. Student attitudes toward older adults were measured pre- and posttest with Polizzi's revised version of the Aging Semantic Differential (ASD). Students were assigned to an intervention group (n = 23) or a control group (n = 20). The intervention group demonstrated significant improvement in attitude toward older adults as compared to the control group (F 14.694, p < .05). This educational approach holds promise for using readily accessible technology to connect the generations.
