The use of the Internet as a teaching tool continues to grow in popularity at colleges and universities. We consider, from the students’ perspective, the use of an Internet approach compared to a lecture and lab‐based approach for teaching an introductory course in statistical methods. We conducted a survey of introductory statistics students. Contradictory to what was hypothesized by the authors, they favoured keeping the lecture and lab‐based approach for teaching the class. 相似文献

This article presents a model featuring two types of emotion regulation—reactive and deliberate—and discusses the developmental trajectory of both types. We argue that the later-developing capacity for deliberate control builds on and coevolves with earlier-developing reactive control. Findings from the field of developmental neuroscience are mapped onto this model. The focus is on specific neural "hubs," such as the anterior cingulate cortex and the orbitofrontal cortex, which serve as epicenters for the coupling of cortical and subcortical processes. We propose that an increasing coordination between brain regions during emotional situations subserves more effective and efficient regulation with development. This framework can be used to explain different developmental pathways of regulatory styles that can, for example, lead to aggressive versus anxious modes of emotion regulation. The implications of this framework can help guide educational policy by supporting prevention and intervention strategies for children exhibiting difficulties with emotion regulation. 相似文献

We study how classic organizational structure dimensions should be altered to be more adapted to organizational knowledge sharing. In particular, we look at the dimensions: coordination, centralization, formalization, and specialization, in their relationship to the concept of knowledge sharing. Empirical data was collected by means of a questionnaire in two companies. Our findings indicated that expected relationships, such as the negative effect of centralization or the positive effect of lower formalization, were not found. Interdependency and knowledge complexity, caused by specialization, had an important interacting effect on the relationship between coordination and knowledge sharing. A comparison between the two companies revealed that the organization-specific context in which the coordination is applied influences the potential of this coordination for knowledge sharing. 相似文献

This article deals with the writing of hypertext during regular school lessons. We suppose that hypertext-environments can be used as “cognitive tools” to promote the comprehension of semantic relationships within a subject and the reflection about knowledge structures. From research on learning by writing traditional text (Bereiter &; Scardamalia 1987), it can be expected that the constitutive features of “hypertext” must be comprehensible for leaner. In this study, we focus in particular on the question: Which metaphors are helpful to introduce the main idea of “hypertext” as a cognitive tool? In an explorative field study, we examined two parallel classes constructing hypertexts during their regular school lessons. The teachers in both classes used completely different metaphors to introduce the concept of hypertext. The metaphor chosen influenced both the structures of the completed hypertext-documents and the discussion about the subject matter. The space-metaphor seems to be especially appropriate to introduce the concept of hypertext to the learner in such a way that a creative interaction between the structure of the hypertext and the semantic structure of the subject could result. Three tests were administered to measure the degree to which knowledge about semantic relations and structures was acquired. The class that had discussed hypertext with spatial metaphors showed significantly better results than the parallel class. 相似文献

There is a consensus that dyslexia is on a continuum with normal reading skill and that dyslexics fall at the low end of the
normal range in phonological skills. However, there is still substantial variability in phonological skill among dyslexic
children. Recent studies have focused on the high end of the continuum of phonological skills in dyslexics, identifying a
“surface” dyslexic, or “delayed” profile in which phonological skills are not out of line with other aspects of word recognition.
The present study extended this work to a longitudinal context, and explored differences among subgroups of dyslexics on a
battery of component reading skills. Third grade dyslexics (n=72) were classified into two subgroups, phonological dyslexics and delayed dyslexics, based on comparisons to younger normal
readers at the same reading level (RL group). The children were tested at two points (in third and fourth grade). The results
revealed that the classification of dyslexics produced reliable, stable, and valid groups. About 82 percent of the children
remained in the same subgroup category when retested a year later. Phonological dyslexics were lower in phoneme awareness
and expressive language. Delayed dyslexics tended to be slower at processing printed letters and words but not at rapid automatic
naming of letters, and relied more heavily on phonological recoding in reading for meaning than did phonological dyslexics.
A subset of the delayed dyslexics with the traditional “surface dyslexic” pattern (relatively high pseudoword and low exception
word reading) was also identified. The surface subgroup resembled the RL group on most measures and was not very stable over
one year. The results are discussed in light of current models of dyslexia and recent subgrouping schemes, including the Double-Deficit
Hypothesis. 相似文献
