In the new science and technology junior-high-school curriculum in Israel, it is recommended that the cell topic be taught
“longitudinally in conjunction with other study contents”. This recommendation confers a change in teaching the cell topic
and provides an opportunity to form meaningful relationships between biological phenomena at the macro-level and their cellular
explanations. Here, we examine junior-high-school science and technology teachers’ pedagogical content knowledge (PCK) with
regard to the cell topic and the formation of macro-micro relations, ten years following the publication of the change in
the curriculum. Teachers in this study participated in three focus groups (n = 59) and one workshop (n = 12). In addition, six experienced teachers were interviewed in the course of this study. Specific tools were developed
to capture the teachers’ PCK. We found that the teachers had changed their way of teaching the cell topic only superficially:
they did not undergo any deep change. Despite the importance the teachers placed on teaching and learning the cell topic,
their concerns about their students’ comprehension difficulties reduced the time they devoted to teaching the topic in class.
The teachers were also found to have no PCK capacity to integrate biological phenomena at the macro-level with their cellular
explanations. In addition, a duality was identified among the teachers with regards to relating macro- and micro-levels in
biology and in chemistry. 相似文献

Based on a survey of rural school districts in Western China, this essay explores the effects of fiscal centralisation on the relationship between local governance and school district management, most particularly on how managerial power is distributed in the rural education sector. The essay also examines some of the possible effects that changes in managerial arrangements may have on teacher incentives and on educational quality as measured by student test scores. Our analysis suggests that teachers’ incentives and students’ education performance are unlikely to benefit from the excessive centralisation of decision-making power or from incessant horizontal level power struggles among different government bodies. 相似文献

The lexical quality hypothesis assumes that skilled readers rely on high quality lexical representations that afford autonomous
lexical retrieval and reduce the need to rely on top-down context. This experiment investigated this hypothesis by comparing
the performance of adults classified on reading comprehension and spelling performance. ‘Lexical experts’, defined by above
average performance on both measures, were compared with individuals who are good readers/poor spellers, poor readers/good
spellers, or poor on both measures. Sentences finishing with a homograph (e.g., She danced all night at the ball) were followed by a probe word and participants had to decide whether it had occurred in the sentence. Critical probe words
were related to either the sentence-congruous or the sentence-incongruous meaning of the homograph (e.g., waltz vs. throw). Lexical experts showed less interference from related probes than the other groups. When the sentences were presented at
fast rates, poorer spellers showed interference for sentence-congruous but not sentence-incongruous probes. However, at slower
presentation rates, all groups showed equivalent interference for both types of probes. The results support the lexical quality
hypothesis by showing that high quality lexical representations, indexed by better spelling, are associated with reduced reliance
on sentence context.

The authors examined the association between relational health and student adjustment to college. Data were collected from 138 undergraduate students completing their 1st semester at a large university in the mid‐southern United States. Regression analysis indicated that higher levels of relational authenticity were a predictor of success during the 1st semester; no significant findings were detected for relationships between relational empowerment and engagement constructs and adjustment. Suggestions for promoting relational development are provided. 相似文献

Plagiarism has been a problem plaguing academia for centuries. The Internet has made it easier than ever to copy material from one electronic document and paste it into another. Many cases are unintentional, as writers are unaware of the rules regarding plagiarism. This paper provides an overview of plagiarism and describes a project in which librarians partnered with the assistant dean of a graduate science program to educate students about the perils of plagiarism and encourage ethical writing practices. 相似文献
