This study examined the role of emotion in the process of news diffusion following the Space Shuttle Columbia disaster. Respondents reported both sadness and anger, but sadness was the predominant emotional response. Early learners reported more sadness, but emotional response was unrelated to the initial source of the news. Regarding interpersonal news diffusion, individuals who reported more sadness were more likely to pass the news on to others and spent more time discussing the event. Anger was associated with contacting a greater number of people. Individuals who contacted more people and spent more time in discussion reported stronger emotional (but not informational) motives for talking with others, and were more likely to say that they felt better after interpersonal contact. Overall, the findings suggest that interpersonal news diffusion and discussion function, in part, as ways to cope with emotional responses to news coverage. 相似文献

Textbooks play an important part in the design of instruction. This study analyzed the presentation of fractions in textbooks
designed for the elementary grades in Kuwait, Japan, and the USA. The analysis focused on the physical characteristics of
the books, the structure of the lessons, and the nature of the mathematical problems presented. Findings showed USA and Kuwaiti
mathematics textbooks are larger than Japanese textbooks; this larger size is consistent with a great deal of repetition.
The Japanese texts do not address fractions until the third grade; they use linear models and connect fractions with measurement.
In the USA and Kuwait, fractions are introduced in the first grade. The Harcourt text uses concrete material to help students
learn fraction procedures. For the Kuwaiti series, the lessons depend on using some pictorial representation of the area model
to illustrate fraction ideas. All these textbooks focus on standard algorithms as the main computational methods. 相似文献

Computational estimation has not yet established a place in the Kuwaiti national curriculum. An attempt was made to include
it during the early 1990s, but it was dropped by the Kuwaiti Ministry of Education because of the difficulties teachers had
teaching it. In an effort to provide guidance for reintroducing the concept into the curriculum, this study reports on mathematics
teachers’ understanding of the meaning of computational estimation and their views about its significance in the elementary
and middle school curricula in Kuwait. Data gathered from 59 elementary and middle schools teachers in Kuwait revealed that
more than 60% of teachers equate computational estimation with rounding. While two-thirds of the teachers viewed computational
estimation to be an important skill for daily life; only one-fifth (20%) saw it as important in mathematics education. More
than half of the teachers either disagreed with the idea of teaching computational estimation or only wanted to teach it in
limited situations. Most were concerned about the difficulty of learning computational estimation or feared that teaching
computational estimation would cause problems with students’ development of standard algorithms for determining an exact answer.
These findings reveal the challenge that mathematics educators face in introducing computational estimation into the mathematics
curriculum. In order for computational estimation to be taught in elementary and middle school classrooms, teachers need to
understand the concept and its value in education. Teacher education needs to focus on helping teachers better understand
the concept of computational estimation and appreciate its value for instruction. 相似文献

Objective: To evaluate intermittent Kangaroo Mother Care (KMC) with additional opportunities to breastfeed on weight gain of low birth weight (LBW) neonates with delayed weight gain. Methods: 40 LBW neonates were followed to see whether KMC with additional opportunities to breastfeed improved weight gain. Results: In the KMC group, the mean age of regaining birth weight was significantly less (15.68 vs. 24.56 days) and the average daily weight gain was significantly higher (22.09 vs. 10.39 g, p < .001) than controls. Conclusion: KMC with additional opportunities to breastfeed was found to be an effective intervention for LBWs with delayed weight gain and should be considered to be an effective strategy. 相似文献

With the development of the Information and Communication Technologies, great masses of information are published in the Web. In order to reuse, to share and to organise them in distance formation and e‐learning frameworks, several research projects have been achieved and various standards and modelling languages developed. In our previous article, the limits of theses languages were examined and a new method named the recursive entity modelling method (REMM) was established to overcome these limits. But, when it was revised, some limitations were discovered. So, in this paper, an improved version of the REMM will be proposed, and the diagram of classes for a scenario modelled by this version will be established. In addition, both the learning scenario package and the generic XML schema permitting to implement these scenarios will be conceived. 相似文献

This study investigated the degree that Science and Engineering Practices (SEPs) criteria from the Next Generation Science Standards (NGSS) were included in self-reported teaching practices of twelfth-grade science teachers in Jordan. This study sampled (n?=?315) science teachers recruited from eight different public school directorates. The sample was surveyed using an instrument adapted from Kawasaki (2015). Results found that Jordanian science teachers incorporate (SEPs) in their classroom teaching at only a moderate level. SEPs applied most frequently included ‘using the diagram, table or graphic through instructions to clarify the subject of a new science,’ and to ‘discuss with the students how to interpret the quantitative data from the experiment or investigation’. The practice with the lowest frequency was ‘teach a lesson on interpreting statistics or quantitative data,’ which was moderately applied. No statistically significant differences at (α?=?0.05) were found among these Jordanian science teachers’ self-estimations of (SEP) application into their own teaching according to the study’s demographic variables (specialisation, educational qualification, teaching experience). However, a statistically significant difference at (α?=?0.05) was found among Jordanian high school science teachers’ practice means based on gender, with female teachers using SEPs at a higher rate than male teachers. 相似文献
