Students have been largely ignored in discussions about how best to teach science, and many students feel the curriculum is
detached from their lives and interests. This article presents a strategy for incorporating students’ interests into the formal
Biology curriculum, by drawing on the political meaning of “shadow government” as alternative policies developed by parties
not in office. A “shadow curriculum” thus reflects the interests and information needs of those who have no voice in deciding
what the formal curriculum should include, although they are the ones who are most influenced by it. High school students’
interests in three Biology topics were identified (n = 343) and retested on another student sample (n = 375), based on their solicited questions as indicators for interests. The results of this exploratory case study showed
that half of the questions asked by students in the areas of genetics, the cardiovascular system and the reproductive system
are not addressed by the national curriculum. Students’ questions were then expressed in the curricular language of principles,
phenomena and concepts in order to create a shadow curriculum. A procedure that could be used by other researchers and practitioners
to guide the development of a curriculum that is more aligned with student interests is suggested. 相似文献

At a top psychology journal, Psychological Science (PS), submissions peak during the summer months. We tested whether this seasonal submission bias decreases the likelihood of a paper being accepted in that period. Month of submission data was obtained for all 575 publications in PS for the period 2003–2006. Whereas submissions to PS were higher in the summer, there was no evidence that most accepted publications were originally submitted in the summer. Thus, contributors submit to PS when the likelihood of acceptance is the lowest – creating their own entrance barrier. A similar seasonal pattern was not identified for Personality and Social Psychology Bulletin, another top psychology journal. Using the Web of Knowledge database, we further assessed whether overcoming the seasonal entrance barrier influences the number of citations a paper receives in subsequent years. We discuss the possibility that the different rejections policies in the two journals, employing desk rejections or not, may explain this discrepancy, and explore a range of alternative hypotheses. 相似文献

The importance of feedback for learning has been firmly established over the past few decades. The question of whether feedback plays a significant role in the statistical learning abilities of adults with dyslexia, however, is currently unresolved. Here, we examined the role of feedback in grammaticality judgment, type of structural knowledge, and confidence rating in both typically developed and dyslexic adults. We implemented two artificial grammar learning experiments: implicit and explicit. The second experiment was directly analogous to the first experiment in all respects except training format: the standard memorization instruction was replaced with an explicit rule-search instruction. Each experiment was conducted with and without performance feedback. While both groups showed significantly improved learning in the feedback-based explicit artificial grammar learning task, only the typically developed adults demonstrated higher levels of conscious structural knowledge. The present study demonstrates that the basis for the grammaticality judgment of adults with dyslexia differs from that of typically developed adults, regardless of increase in the level of explicitness. 相似文献

This study examined the differences in processing between regular and dyslexic readers in a lexical decision task in different
visual field presentations (left, right, and center). The research utilized behavioral measures that provide information on
accuracy and reaction time and electro-physiological measures that permit the examination of brain activity during cognitive
processing. Two groups of university students, regular and dyslexic readers, were matched on age, gender, intelligence, socioeconomic
status, and handedness. A lexical decision task was used in order to examine the processes during word recognition. Subjects
were required to decide whether a sequence of letters constituted a real word existing in spoken language or whether the stimulus
seen was not an accurate word. For the behavioral measures, it was found that the dyslexics read slower and with more errors
than the regular readers. Moreover, the ERP components appeared later in dyslexics as compared to regular readers in this
task. The performance of the dyslexics improved and even approached that of the regular readers when the stimuli were presented
to the left visual field. Thus, it seems that the dyslexics were relying more on their right hemisphere for linguistic processing,
whereas the regular readers were relying more on their language areas in the left hemisphere. 相似文献

We restrict the discussion of root clustering (exclusion) to rational convex regions. A region in this family is constructed as the intersection of an infinite number of half planes. The root clustering criterion involves the positivity of a set of polynomials with respect to the region's parameter. 相似文献
