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

First an overview is given about the actual national and international situation concerning standardized testing. Then two major reasons are presented why accountability systems based on standardized testing have become so widespread: (a) the missing validity and reliability of teachers’ assessment of students’ achievement, and (b) the important role standardized testing plays for out-put management in educational systems.On the basis of these considerations Alfred North Whitehead’s critical remarks on external standardized testing are presented. Whitehead’s main point is that external standardized testing limits the freedom of teachers to adapt to the complex, situation specific circumstances in order to obtain a maximum of the creative learning process for students who are conceived as specialists. Instead external testings lead to “teaching to the test.” As a consequence, the attitude of creative, adventurous exploration is undermined and substituted by simple pattern recognition, narrow visions, and even boredom. Finally, the question is raised whether there is any possibility of developing a measurement tool which on the one side meets scientific test criteria, and on the other side is still flexible enough to do justice to needs of individual schools – which according to Whitehead are the essential educational unit – and not vice versa, as it is the case at present with external standardized testing. That such a flexible approach to evaluation is possible is demonstrated by the presentation of the basic ideas of the MSS (Module Approach to Self-Evaluation of School Development Projects) which has been developed and examined in ten schools by the author and his collaborators. 相似文献

Innovation has moved to the foreground in regional policy in the last decade. Concrete policies were shaped by “best practice models” derived from high-tech areas and well performing regions. These are often applied in a similar way across many types of regions. Here an attempt is made to show that there is no “ideal model” for innovation policy as innovation activities differ strongly between central, peripheral and old industrial areas. In this paper we analyse different types of regions with respect to their preconditions for innovation, networking and innovation barriers. Based on this classification different policy options and strategies are developed. 相似文献

In this context we do not mean the production of educational films by various institutes, publishers, and professional film-makers because they have to follow a given standard in technique, theme and reference to the school curriculum. 相似文献

Various theoretical concepts such as plasticity, competence, and potential have recently been applied to underline the possibility of later‐life development and change. Value and limitations of these concepts are discussed in view of learning in later life. A review of the special case of Austria and the educational attainments of its elderly indicates that social reality is slow in its transformation and that the disadvantageous educational achievements credited to today's older people hardly encourage them in pursuing later‐life studies. The paper reports results obtained by means of two questionnaires filled out by older students and teachers. This empirical investigation examines the influence of societal norms, social setting in institution‐related learning situations (age‐homogeneity vs. age‐heterogeneity), and instructors’ attitudes toward older students. The results demonstrate that permanent education and proper stimulation of the learning processes depend on a complex relationship between (competent) individuals, their social surroundings, and learning conditions that often prove unfavorable. 相似文献

Emphasis on improving higher level biology education continues. A new two-step approach to the experimental phases within
an outreach gene technology lab, derived from cognitive load theory, is presented. We compared our approach using a quasi-experimental
design with the conventional one-step mode. The difference consisted of additional focused discussions combined with students
writing down their ideas (step one) prior to starting any experimental procedure (step two). We monitored students’ activities
during the experimental phases by continuously videotaping 20 work groups within each approach (N = 131). Subsequent classification of students’ activities yielded 10 categories (with well-fitting intra- and inter-observer
scores with respect to reliability). Based on the students’ individual time budgets, we evaluated students’ roles during experimentation
from their prevalent activities (by independently using two cluster analysis methods). Independently of the approach, two
common clusters emerged, which we labeled as ‘all-rounders’ and as ‘passive students’, and two clusters specific to each approach:
‘observers’ as well as ‘high-experimenters’ were identified only within the one-step approach whereas under the two-step conditions
‘managers’ and ‘scribes’ were identified. Potential changes in group-leadership style during experimentation are discussed,
and conclusions for optimizing science teaching are drawn. 相似文献
