Concept maps consist of nodes that represent concepts and links that represent relationships between concepts. Various studies
have shown that concept mapping fosters meaningful learning. However, little is known about the specific cognitive processes
that are responsible for such mapping effects. In a thinking-aloud study, we analyzed the relations between cognitive processes
during concept mapping as well as the characteristics of the concept maps that the learners produced and learning outcomes
(38 university students). To test whether differences in learning outcome are due to differences in general abilities, verbal
and spatial abilities were also assessed. In a cluster-analysis two types of ineffective learners were identified: ‘non-labeling
mappers’ and ‘non-planning mappers’. Effective learners, in contrast, showed much effort in planning their mapping process
and constructing a coherent concept map. These strategies were more evident in students with prior concept-mapping experience
(‘advanced beginners’) than in those who had not used this learning strategy before (‘successful beginners’). Based on the
present findings, suggestions for a direct training approach (i.e., strategy training with worked-out examples) and an indirect
training approach (i.e., supporting the learners with strategy prompts) were developed. 相似文献

The article briefly describes the Slavic collection created by Joel Sumner Smith, which became the basis of Yale University Library's Slavic, East European, and Central Asian Collection. It then discusses preparation for digitizing it and the processes involved in creating this digital collection, as well as some of the problems encountered. 相似文献

The authors of this paper compared the views of Slovenian and Portuguese preschool teachers about the importance of play and movement for the preschool children. In the paper, they focused on the question: Does physical activity of preschool teachers (spontaneous or planned) impact the planning and implementation of movement activities in their kindergarten group? They also analyzed the influence of subjective theories on the planning of movement activities and the realization of the curriculum objectives in the field of movement. Most of the preschool teachers in Slovenia and Portugal give priority to natural forms of movement in nature and play, allowing the movement of the fingers, palms, and hands. Research has shown a link between physical activity of preschool teachers and their views on the importance of the implementation of the movement activities of preschool children. The authors also noted that the quality of the implementation of the education process in kindergartens in the area of movement activities depends on their subjective theories to a great extent and on the level of professional competence referred to the discussed topic. 相似文献

We propose a projection based multi-moment matching method for model order reduction of quadratic-bilinear systems. The goal is to construct a reduced system that ensures higher-order moment matching for the multivariate transfer functions appearing in the input-output representation of the non-linear system. An existing technique achieves this for the first two multivariate transfer functions, in what is called the symmetric form of the multivariate transfer functions. We extend this framework to an equivalent and simplified form, the regular form, which allows us to show moment matching for the first three multivariate transfer functions. Numerical results for three benchmark examples of quadratic-bilinear systems show that the proposed framework exhibits better performance with reduced computational cost in comparison to existing techniques. 相似文献

In this article, the author discusses the internship program of the Slavic and East European Collection at Yale University Library, which provides semester-long fellowships to library professionals from Eastern and Central Europe and the former Soviet Union. The program began in 1993 and is ongoing. The author details its history, including how it has been funded, and discusses what the program includes and the logistics of running it. Participants are listed, along with excerpts from some of their final reports and selected post-fellowship activities. 相似文献

In this text, the authors are analyzing preschool care and education in local community. They are focusing on the problem of information transfer between the kindergarten, parents and local community, as well as the model of relationship participation. Cooperation between parents, kindergarten and local community is an important element in the preschool institution quality, because it changes inner relationships, climate and culture. Expectations about cooperation in some authors' views (Resman, 1992; Schleicher, 1989; Coleman, 1998; Ryan, 1995) depend on tradition, objectives, social context, legal framework and situational demands. The research data show that Slovene kindergartens have more consumer-like relationships with parents instead of partnership. Kindergartens are clear about important information concerning their pedagogical work and organization, but they do not include parents in making decisions about the developing and executing of programs. 92.3% of parents think that the information they receive is clear, understandable only 89.6% think they are frequent. More then half of the interviewed parents frequently or always participate in kindergarten life and work, only about 43% believe that they can co-influence the development or realization of the programme. Parents also think that the local community is not giving them enough information about preschool care problems, because only 10.2% are included in solving current preschool care problems in their municipality. 相似文献

Arginase activity is important in polyamines and nitric oxide production which are required for the normal growth of placenta and embryo. A considerable arginase activity is observed in amniotic fluid in women at the end of pregnancy. Lecithin to sphingomyelin (L/S) ratio is widely used in order to assess fetal lung immaturity and prevention of neonatal respiratory distress syndrome, the major cause of neonatal morbidity and mortality. The purpose of our study was to determine if there is a relationship between arginase activity and L/S ratio in amniotic fluid. The study included 170 pregnant women, 18–43 years old, with normal and pathological pregnancy. The arginase activity was measured on the basis of the determination of the amount of liberated ornithine from arginine as substrate. The L/S ratio was done by using a thin layer chromatography. Increased level of arginase activity correlates with the fetal lung maturity. Arginase activity and L/S values may be useful biochemical data, for intrauterine baby maturity. 相似文献
