Phillip Cam recently published a study on the separation between the teaching and learning of classic school curriculum (CSC) on the one hand and morality on the other. He suggests an approach to integrate them. The goal of this article was to suggest a complementary alternative approach, to Cam’s. Based on a MacIntyrean paradigm, I argue that seeing the CSC (such as math, biology, literature and history) as ‘practices’ would also enable that integration. This approach differs from the one proposed by Cam, since it preserves the structure of the CSC. Nevertheless, I will demonstrate how this approach leads to a number of changes in the formation, teaching and learning of school curriculum. As background, I will briefly describe R.S. Peters’ attempt to find an internal justification for the teaching and learning of school curriculum and point to some weaknesses it contains. My proposal can be understood as deriving from the same principle, of another famous educational initiative, Mortimer Adler’s ‘Great Book Project’. Toward the end of the article, I will demonstrate why Adler’s project differs from mine, and why it does not meet the goal of integrating learning school curriculum with moral education. 相似文献

Some ideas have dramatically more impact than others – they may overturn existing paradigms or launch new areas of scientific inquiry. Where do such high impact ideas come from? Are some search processes significantly more likely to lead to breakthrough idea generation than others? In this research, we compare “high impact” papers from the social sciences with random-but-matched articles published in the same journals in the same years. We find that search scope, search depth, and atypical connections between different research domains significantly increase a paper's impact, even when controlling for the experience and prior publishing success of the author(s). 相似文献

The introduction of computers into education raises questions such as: are computers in education effective? If they are, in what sense? What are the most effective strategies for using computers in education? How should teachers be encouraged to use them?
To answer these questions a large-scale experiment (Project Comptown) was carried out in Israel, to test ways and means under real rather than laboratory conditions. This project is a research-oriented educational intervention, applying massive computerisation of schools and their 'close environment' to two localities in Israel (Arad and Ashkelon). Our starting point was the premise that computerisation of education is an inevitable process. Consequently, turning the computer into a 'cultural tool' in schools becomes a major challenge, aiming to narrow the gap between 'school culture' and 'real-world culture'. The main objectives for Project Comptown are: [1] To create a computer culture in schools; [2] To use the computer's potential for innovative teaching and learning, both inside and outside schools. To achieve these, we identified a number of principles which we considered pre-conditions for an 'appropriate' computer strategy in schools. 相似文献

The present study aimed to extend understanding of preschoolers’ early spelling using the Vygotskian (Mind in society: the development of higher psychological processes, Cambridge, Harvard University Press, 1978) paradigm of child development. We assessed the contribution of maternal spelling support in predicting children’s word spelling level beyond the contribution of three internal child measures: early literacy (phonological awareness and letter naming), private speech while spelling (self-directed talk), and behavioral regulation. Children’s private speech during spelling—their tool to regulate thinking—has not yet been studied in the early literacy context. Fifty Israeli preschoolers (M = 68.66 months) of middle-high SES were videotaped while spelling words with their mothers and while spelling these words independently. Children’s phonological awareness, letter naming, and behavioral regulation were assessed individually. Results showed that children’s internal measures (early literacy, private speech while spelling, and behavioral regulation) predicted children’s early spelling (63 % of the variance), and the external measure of maternal spelling support added uniquely (12 %), together explaining 75 % of the variance in children’s spelling level. Findings suggested that mothers adjust their spelling support to meet young children’s existing literacy skills but also coach children to strive toward higher spelling performance. Furthermore, the study illuminates the role of a new measure in the context of children’s early literacy—private speech during spelling. 相似文献

The aim of the present study was to compare the effect of an increasing-distance, interval-training programme and a decreasing-distance, interval-training programme, matched for total distance, on aerobic and anaerobic physiological indices. Forty physical education students were randomly assigned to either the increasing- or decreasing-distance, interval-training group (ITG and DTG), and completed two similar relevant sets of tests before and after six weeks of training. One training programme consisted of increasing-distance interval-training (100–200–300–400–500?m) and the other decreasing-distance interval training (500–400–300–200–100?m). While both training programmes led to a significant improvement in VO2 max (ES?=?0.83–1.25), the improvement in the DTG was significantly greater than in the ITG (14.5?±?3.6 vs. 7.8?±?3.2%, p?<?.05). In addition, while both training programmes led to a significant improvement in all anaerobic indices (ES?=?0.83–1.63), the improvements in peak power (15.7?±?7.8 vs. 8.9?±?4.7), mean power (10.6?±?5.4 vs. 6.8?±?4.4), and fatigue index (18.2?±?10.9 vs. 7.0?±?14.2) were significantly greater in the DTG compared to the ITG (p?<?.05). The main finding of the present study was that beyond the significant positive effects of both training programmes on aerobic and anaerobic fitness, the DTG showed significant superiority over the ITG in improving aerobic and anaerobic performance capabilities. Coaches and athletes should therefore be aware that, in spite of identical total work, an interval-training programme might induce different physiological impacts if the order of intervals is not identical. 相似文献

In this article, the authors analyze the popular search queries used in Google and Yahoo! over a 24-month period, January 2004–December 2005. They develop and employ a new methodology and metrics to examine and assess the digital divide in information uses, looking at the extent of political searches and their accuracy and variety. The findings indicate that some countries, particularly Germany, Russia, and Ireland, display greater accuracy of search terms, diversity of information uses, and sociopolitical concern. Also, in many English-speaking and Western countries most popular searches were about entertainment, implying a certain gap within these countries between the few who search for economic and political information and the many who do not. 相似文献

Selection to programmes for gifted students in Israel, performed in the second grade, relies on raw ability and achievement test scores, irrespective of age, thereby ignoring the well-known effect of within-grade age differences on test scores. Employing the entire cohort of third graders of legal age (67,366 students, 1.4% of whom were enrolled in a gifted programme) in 2011, this study examined the relationship between chronological age and the probability of acceptance to programmes for the gifted in Israel. The results reveal an almost perfect correlation between chronological age and the probability of being selected for a gifted programme (r2 = 0.92): older students have approximately 3.5 times greater chance of acceptance than younger students. Reliance on raw ability and achievement test scores, unadjusted for age, in selection to gifted students programmes is thus shown to be biased in favour of older students and to unintentionally discriminate against younger students. 相似文献

Textual computer-mediated communication gives rise to conversational multitasking—participation in several concomitant synchronous textual conversations. This study examined how this communication competence is affected by several visual parameters—the distance between conversation windows, number of windows, and window size. Results show that comprehension of concomitant textual conversations is not affected by the distance between conversation windows, and that the advantage of separating conversation threads into distinct windows is greater when overall window size is larger. This study considers the implications and applications of these results to communicative multitasking phenomena, in general, which become prevalent in technologically advanced societies. 相似文献

The majority of Internet users search for medical information online; however, many do not have an adequate medical vocabulary. Users might have difficulties finding the most authoritative and useful information because they are unfamiliar with the appropriate medical expressions describing their condition; consequently, they are unable to adequately satisfy their information need. We investigate the utility of bridging the gap between layperson and expert vocabularies; our approach adds the most appropriate expert expression to queries submitted by users, a task we call query clarification. We evaluated the impact of query clarification. Using three different synonym mappings and conducting two task-based retrieval studies, users were asked to answer medically-related questions using interleaved results from a major search engine. Our results show that the proposed system was preferred by users and helped them answer medical concerns correctly more often, with up to a 7 % increase in correct answers over an unmodified query. Finally, we introduce a supervised classifier to select the most appropriate synonym mapping for each query, which further increased the fraction of correct answers (12 %). 相似文献
