Data from both neuropsychological and neuroimaging studies have implicated the left inferior parietal cortex in calculation. Comparatively less attention has been paid to the neural responses associated with the commission of calculation errors and how the processing of arithmetic errors is modulated by individual differences in mathematical competence. Do more competent individuals exhibit a different brain response to errors than less mathematically able individuals? These outstanding questions were addressed in the present functional Magnetic Resonance Imaging (fMRI) study through an investigation of which brain regions respond more to erroneously versus correctly solved arithmetic problems while a group of 24 adult participants with varying levels of mathematical competence solved problems of all four arithmetic operations. Despite high levels of accuracy, a robust main effect of accuracy (incorrect vs. correct) was observed in both medial and lateral regions of the prefrontal cortex. These regions have frequently been associated with both the detection of errors and the deployment of cognitive control following an error. Furthermore, mathematical competence was found to modulate the activation of an area in the right dorsolateral prefrontal cortex. Specifically, individuals with relatively higher mathematical competence (n = 12) were found to activate this region more for incorrectly solved trials than their less mathematically competent peers (n = 12). Taken together, these findings suggest that the commission of arithmetic errors modulates responses of prefrontal regions and, moreover, that activation of the right lateral prefrontal cortex during arithmetic errors is affected by individual differences in mathematical competence. In view of the evidence associating the lateral prefrontal cortex with the implementation of cognitive control, we suggest that individuals with relatively high mathematical competence may exhibit greater awareness of calculation mistakes and implement greater control following the commission of errors. 相似文献

Radio is migrating to digital transmission, expanding its offerings to include captioning for individuals with hearing loss. Text display radio requires a large amount of word throughput with minimal screen display area, making good user interface design crucial to its success. In two experiments, we presented hearing, hard-of-hearing, and deaf consumers with National Public Radio stories converted to text and examined their preferences for and reactions to midsized and small radio text displays. We focused on physical display attributes such as text color, font style, line length, and scrolling type as well as emergency alert messages and emergency prompts for drivers, announcer identification schemes, and synchronization of audio and text. Results suggest that midsized, Global Positioning System (GPS)-style displays were well liked, synchronization of audio and text was important to comprehension and retrieval of story details, identification of announcers was served best with a combination of name change in parenthesis and color change, and a mixture of color and flashing symbols was preferred for emergency alerting. 相似文献

Many residence hall staff have attempted to align the academic subculture of the faculty with the opposing extracurricular subculture of students by moving closer to the academic sector. Studies at Harvard University and at Hampshire College are summarized to indicate the failure of traditional house systems or residence hall programming to successfully bridge the gap between the academic and living subcultures. It is suggested that student personnel staff should focus on their unique contribution in higher education: the facilitation of students' personal development and interpersonal communication skills. 相似文献

This study investigated the hypothesis that prompting students to self-assess their interest and understanding of science concepts and activities would increase their motivation in science classes. Students were randomly assigned to an experimental condition that wrote self-assessments of their competence and interest in science lessons or a control condition that wrote summaries of those same lessons. Writing activities were 10?min long and were given approximately once a week for eighteen weeks. Student motivation was assessed via self-report surveys for achievement goals and interest in science before and after the intervention. Students in the experimental condition showed higher endorsement of mastery goals and reported greater situational interest in science topics after the intervention compared to students who summarised the lessons. Increases in situational interest predicted higher individual interest in the domain. Results indicate an instructional practice requiring just 3?hours out of a semester of instruction was sufficient to achieve these effects on motivation in science classes. 相似文献

Contemporary discourses of social justice in education, disability, mental health, social policy and feminist studies are refracted increasingly through concerns about psychological and structural vulnerabilities created by the crises of late capitalism. Focusing on developments in British social policy generally and educational research specifically, this paper uses the authors' contrasting perspectives on two discernible discourses of vulnerability emerging in these contexts. One elevates the recognition of collective vulnerability as a springboard for new conceptualisations of resistance that disrupt materialist narratives of the human subject as a coherent, unified and rational agent of history. A second discourse offers a materialist understanding that locates vulnerability as both driver and product of a ‘therapeutic culture’, arguing that a psycho-emotional focus for vulnerability offers a diminished and ineffective subjectivity that belies rhetorics of resistance. These contrasting perspectives generate and emerge simultaneously from new understandings of the human subject. The paper evaluates the implications of using vulnerability to frame expectations of human subjects for everyday educational practices and relationships. It concludes by suggesting empirical questions that need exploring. 相似文献

In this article, we explore the meaning potentials of teacher education in terms of the significance of a research-based approach and the different pedagogic identities that such an approach implies. The study’s aim is to examine the important factors for education to be considered research-based and to identify and analyse the research base of teacher education in Sweden. The results from the analysis of a large number of course documents and from a survey administered to teachers and students in four teacher education programmes indicate that the emerging potential meaning is that teacher education is generally a strongly framed professional education with a relatively weak and adapted research base. The analysis of the classification and framing of disciplinary content and pedagogy in the Swedish teacher education curriculum points at different pedagogic identities emerging from the different meaning potentials that are made available to the students. We argue that a thorough understanding of research-based teacher education needs to be grounded in both course content and its research base as well as other possible pedagogical aspects of research-based education; the education as a whole must be included in the concept of research-based education. 相似文献

Accountability-oriented reforms demand immediate and continual gains on achievement test, for all students, and without diminishing other outcomes or undermining instruction. This paper describes a framework for aligning classroom assessment and external testing with the aim of negotiating these seemingly contradictory goals. The framework varies the sensitivity to instruction and the representations of knowledge across approaches to assessment. Cycles of design- based studies successively refine relationships between a curriculum and the frame that each assessment provides. Doing so, we argue, leverages the unique formative and summative balance across assessments in order to scaffold learning and demonstrate the “consequential” validity of our strategy without compromising curricula, instruction, or the “evidential” validity that warrants their continued use. 相似文献

This article presents a microanalysis of how a group of primary school teachers deals with research evidence in their work. Based on analysis of a group of Norwegian teachers’ interactions over issues of educational research and research-based knowledge, we find that teachers’ representations of educational research particularly center on the following issues: educational research being perceived as circular, ‘polyphonic’, and a matter of accommodation to their experience-based knowledge. These metaphors also shed light upon the dilemmas that arise when research evidence meets teachers’ more contextual knowledge. We conclude that teachers’ practice-based evidence may take new forms with an increased policy focus on research-based evidence, as well as bringing forth challenges for teacher work and professionalism. 相似文献

This study examines how participation in a verbal exchange during an inquiry-based classroom activity allows three college
students and their science instructor to use linguistic signs (choices of words, grammatical structures, discursive structures,
prosody and poetic discourse) to construct authority and expertise. Our work explores linguistic and interactional processes
of identification (the dynamic construction and transaction of expert identity) and examines how discursive strategies adopted
by the professor at different moments of the verbal exchange influence the students’ subsequent discursive practices and perceptions
of authority. We adopt a dialogic, socio-constructivist perspective on identity, viewing personal identities as being partially
constructed via interactional positioning. Our findings reveal that the attainment of expertise involves two different types
of language-mediated processes: the transmission of a professional vision or intension and the emergence of a perception of
agency among students. The former is centered on referential-denotative meanings of speech (elicitation of standard account
and operational definition) while the latter requires effective use of pragmatic–performative functions of speech (non-evaluative
and more than minimal recipient practices). Consideration is given to the need for science instructors to be able to utilize
pragmatic functions of language strategically to encourage students to position themselves within the identity of science
expertise. 相似文献

The localization,diagnostic, and monitoring functions of student ratings in a model for improving university teaching 总被引:1,自引:0,他引:1
Daniel S. Sheehan 《Instructional Science》1976,5(1):77-91
A diversity of student questionnaires are used by colleges and universities to provide data on faculty teaching performance. Yet the purposes for collecting this data are frequently unclear, and at times superficial. Rarely is student rating data used as a tool to improve faculty teaching. A more relevant approach incorporates a variety of types of student ratings into a model for improving university teaching. One type of student rating data is used to identify broad instructional problem areas. Another type pinpoints probable causes and solutions for the instructional problems. Instructional improvement procedures are designed on the basis of this data. A third type of student rating data evaluates the instructional improvement procedures and indicates when modifications are needed. In addition to these three types of student ratings, and the generation of appropriate questionnaires, this paper presents an overview of the teaching improvement model and discusses its effectiveness. 相似文献
