Adolescence is marked by the development of personal identity and is associated with structural and functional changes in brain regions associated with Self processing. Yet, little is known about the neural correlates of self‐reference processing and self‐reference effect in adolescents. This functional magnetic resonance imaging study consists of a self‐reference paradigm followed by a recognition test proposed to 30 healthy adolescents aged 13–18 years old. Results showed that the rostral anterior cingulate cortex is specifically involved in self‐reference processing and that this specialization develops gradually from 13 to 18 years old. The self‐reference effect is associated with increased brain activation changes during encoding, suggesting that the beneficial effect of Self on memory may occur at encoding of self‐referential information, rather than at retrieval.  相似文献

Thirty‐six ophthalmology journals indexed by the Science Citation Index (SCI) in 2003 were selected to study the role of the ‘papers cited rate’ in scientific journal evaluation. The 2‐year, 3‐year, 5‐year, 8‐year, and 10‐year cited rates of these papers were calculated to analyze statistically the correlations with impact factor, 5‐year impact factor, immediacy index, eigenfactor score, article influence score, and total cites. The results of questionnaires sent to 8,525 ophthalmologists were used to analyse the correlations between the papers cited rates for different years and traditional bibliometric indicators. The results showed that eigenfactor score and total cites were better than other indicators, and impact factor was better than the 5‐year impact factor. The 2‐year and 3‐year cited rates of papers were reasonable for evaluating science journals, and the 2‐year cited rate was better than the 3‐year cited rate. The 5‐year (and more than 5 years) cited rates were not significant in evaluating science journals.  相似文献

Current thinking encourages teachers to incorporate a range of assessment practices that are responsive to student thinking and promote student learning. At the same time, teachers are situated in a landscape of accountability, where they are often seen as technicians who implement prescribed curriculum, policies, and procedures with success measured by externally created assessments. This paper considers how teachers navigate this difficult terrain as they incorporate new assessment practices in their classrooms. We report on a two-year project undertaken with 42 teachers of mathematics (Grades 4–12) in Ontario, Canada. Using an analytic framework adapted from Windschitl (Review of Educational Research, 72(2), 131–175.2002), we explore the dilemmas these teachers identified as they met in communities of practice. Our findings highlight the need for coherence in the assessment messages communicated to teachers and provide evidence of the critical role of ongoing collaboration and dialogue to support the development of teachers’ professional judgement and enable change in their assessment practice.  相似文献

Understanding about human origins informs our understanding of what it means to be human. It is reasonable, therefore, to consider that an evolutionary perspective can provide insight into the nature and processes of human learning and education. This article reviews how ideas about evolution have influenced educational thinking in the past. It then considers how understanding of brain development and function is helping to inspire “new thinking” about evolution. The review converges on a range of benefits that may arise from the inclusion of evolutionary concepts within the field of mind, brain, and education. These benefits include scrutiny of evolutionary neuromyth, reconsideration of the cultural and political status of education, insight into notions of individual difference, and help with stimulating and directing research efforts aimed at improving educational outcomes.  相似文献

Maintaining current, relevant curriculum in undergraduate Food Microbiology courses is essential for training future experts in food quality and safety. Having an understanding of the fundamental techniques (for example, polymerase chain reaction [PCR]) that are used in the food industry and regulatory agencies is critical for students entering the workforce. The purpose of this study was to assess the efficacy of integrating molecular methods into an undergraduate Food Microbiology course in both lecture and laboratory settings. Modules on PCR and pulsed‐field gel electrophoresis (PFGE), both of which are currently used by government agencies and the food industry to investigate the presence and persistence of foodborne pathogens, were developed, introduced, and evaluated among 269 students over 4 y. Multiple teaching and learning styles were incorporated through (i) traditional lecture format on the basics of PCR and PFGE; (ii) hands‐on group activities to build upon the lecture instruction; (iii) performing PCR and PFGE in the laboratory; and (iv) group discussions to analyze results from laboratory exercises. Pre‐ and postinstruction evaluations revealed significant increases in understanding and application of both methods in lecture and laboratory settings as demonstrated by 0.60 and 0.51 mean normalized gains for respective PCR and PFGE lectures and 0.50 and 0.56 mean normalized gains in respective labs. Academic year significantly impacted score improvement, potentially due to hidden factors, such as previous exposure to material and student aptitude. This study provides the platform for successful introduction of molecular techniques in an undergraduate Food Microbiology course. The guidelines and materials developed by our group are publicly available for use by other institutions.  相似文献

Although considerable work has been done to develop new educational innovations, few have found widespread acceptance in the classroom. To improve the likelihood of adoption of educational innovations, researchers need to understand why some innovations are adopted and routinely used, while others are not. An initial aspect of the diffusion of innovations, as defined in the classical sociological literature, involves the communication of ideas and concepts related to innovations between individuals. This article presents an expert panel's answer to the following question: “What are the most important characteristics that relate to the dissemination of educational innovations?” As dissemination is a critical facet of the diffusion of an innovation, 45 researchers who received technology and engineering grants from the National Science Foundation (NSF) participated in a Delphi study designed to address this research question. In three rounds, the experts identified and ranked 11 characteristics of educational innovations, 6 characteristics of students, 13 characteristics of faculty members, and 5 characteristics of administrators that can relate to the successful dissemination of educational innovations. The results of this study led to the formation of a Characteristics of Dissemination Success (CODS) framework. This framework offers useful guidance for educational innovators seeking a better understanding of the influences on the dissemination of educational innovations.  相似文献

This paper defines and discusses ‘mood boards’– those assemblages of images and, less frequently, objects, which are used to assist analysis, creativity and idea development in design activity. There is need for discussion since little published information currently exists to guide students and tutors. The paper proposes that mood boards can assist problem finding as well as problem solving. Primarily, mood boards provide a mechanism for students and practising designers to respond to perceptions about the brief, the problem as it emerges and the ideas as they develop. The construction of mood boards potentially stimulates the perception and interpretation of more ephemeral phenomena such as colour, texture, form, image and status. They are, like Debono's lateral thinking techniques, partly responses to an inner dialogue and partly provocation to become engaged in such a dialogue. Examples are drawn from recent work in the field of industrial design at Loughborough University.  相似文献
