Several authors have depicted the learning organization as a model of organization survival in the global economy. Learning organizations are able to adapt to their environments and learn effectively from their actions. This article explores the relationship of information technology systems to learning organizations. The article discusses ways that information technologies may be used to enhance individual, team and strategic‐learning. 相似文献

Much attention has been paid to the delay in writing acquisition caused by irregularities of Russian orthography, but little is known about their effect on reading acquisition. Results of the present longitudinal reading acquisition study of Russian first graders suggest that phonological recoding is the dominant strategy in the initial phase of reading development in Russian, while there is evidence of gradual shift towards orthographic processing in reading high‐frequency regular words. The study confirms that Russian readers encounter difficulties in reading orthographically complex words, where phonological recoding does not completely succeed. These findings are compared with results of reading acquisition studies in other orthographies, and their relevance for models of reading acquisition in different types of orthographies is discussed. 相似文献

We develop a deductive data model for concept-based query expansion. It is based on three abstraction levels: the conceptual, linguistic and string levels. Concepts and relationships among them are represented at the conceptual level. The linguistic level gives natural language expressions for concepts. Each expression has one or more matching patterns at the string level. The models specify the matching of the expression in database indices built in varying ways. The data model supports a declarative concept-based query expansion and formulation tool, the ExpansionTool, for heterogeneous IR system environments. Conceptual expansion is implemented by a novel intelligent operator for traversing transitive relationships among cyclic concept networks. The number of expansion links followed, their types, and weights can be used to control expansion. A sample empirical experiment illustrating the use of the ExpansionTool in IR experiments is presented. 相似文献

The effects of a kindergarten training program in phonological awareness with 209 Swedish-speaking children were followed up until the end of Grade 9. Initial levels of letter knowledge and phonological awareness were positively associated with the level of decoding skill in Grade 3 but not with its growth afterward. The intervention group performed significantly better in decoding in Grade 3, and the difference was maintained until Grade 6. The trained children also scored higher in Grade 9 reading comprehension. Although the results give empirical support for a connection between early phonological awareness training, later word decoding development, and still later reading comprehension, the theoretical explanation for the link between especially word decoding and reading comprehension is far from clear. 相似文献

ABSTRACTSchool bullying is associated with externalizing and internalizing problems, but little is known about whether reading difficulties also play a part. We asked how, in Grades 1 and 2, word reading skills and externalizing/internalizing problems predict the degree to which students are involved in bullying in Grade 3. Using a sample of 480 Finnish children (M age = 7 years 2 months at the beginning of the study), developmental profiles were identified using mixture modeling based on reading skills, as well as externalizing and internalizing problems. In Grade 3, one fifth of the students were involved in bullying as victims, bullies, or bully/victims. Poor readers with externalizing/internalizing problems were most involved as bullies and bully/victims but not as victims. Average readers with externalizing/internalizing problems were also involved in bullying, whereas students with only reading difficulties were not. Skilled readers displayed little externalizing/internalizing problems and were not involved in bullying. 相似文献

ABSTRACTIn the face of organizational transformations, academics are given a role as informal ‘change agents’ in their discipline-specific communities of practice (DCoP). Simultaneous participation in pedagogically oriented communities of practice (PCoP) enables them to promote pedagogical development through brokering at community interfaces. This empirical study explores academics’ experiences of acting as informal change agents at the interfaces of DCoP and PCoP during an organizational transition phase of three years. The longitudinal data were collected with interviews of 13 academics from the fields of science and technology. The findings reveal a variety of pedagogical development activities related to shared meanings, practices, identities, and ways of belonging. The activities are aligned with the organizational transition process and enabled by collegial support. The findings indicate that lack of supportive formal leadership may terminate the informal development activities. The resulting model of change agency provides a novel approach to pedagogical development in higher education. 相似文献

Altogether 1,285 Finnish children were followed up from the end of kindergarten through Grade 1. All were nonreaders at school entrance. The aim was to delineate predictors of resistance to treatment that are evidenced as little or no reading progress during Grade 1. On the basis of reading achievement in Grade 1 spring, four subgroups were formed. These were fast, average, and slow reading acquisition and slow progress in both reading and math. Kindergarten spring scores in phonological awareness, letter knowledge, rapid naming, and number skills differentiated well among the groups, the latter two being more robust predictors. Task avoidance added to the prediction over and above cognitive skills. Its effect disappeared when parental history of reading and math difficulties was included in the equation. The present results depict poor response to instruction as a general learning problem rather than a specific reading difficulty. Poor response to instruction differs from dyslexia also in that treatment resisters start school with cognitive prerequisites that do not indicate severe reading and math problems. 相似文献

This study examined the development of reading skill during the first school year. The predictors were pre-school motivational orientations, coping tendencies, knowledge of the alphabet and phonemic awareness. From 151 pre-school children (6 years of age) rated by pre-school teachers on motivational orientations, 32 non-readers were allocated according to their dominating motivational disposition to one of the following extreme groups: task orientation, social dependence, ego-defensive, and multiple non-task-oriented. Each group included 8 children. The subjects' phonemic awareness and knowledge of the alphabet were assessed. Coping strategies were observed in pre-school during a play-like construction task comprising three induced pressure episodes. At the end of the first grade the children were assessed on word reading skill and again on motivational orientation. Both group comparisons and idiographic analyses were made. Results indicated that pre-school phonemic awareness was associated with first grade word reading skill. Rated task orientation in pre-school enhanced significantly the prediction of fluent word reading. Task-oriented children showed significantly better word reading skill than ego-defensive or multiple non-task-oriented children. Ego-defensive and multiple non-task-oriented subjects showed significantly less task oriented, and more ego-defensive, coping behaviour under pressure than task-oriented subjects. This finding suggests greater vulnerability of ego-defensive and multiple non-task-oriented children which may contribute to diverging reading careers. Idiographic analyses indicated parallel developmental changes in reading skill, motivational orientations and coping patterns confirming the role of motivation in the formation of an individual's reading career. 相似文献
