元认知策略与外语学习 总被引:4,自引:0,他引:4
赵晓光 《白城师范学院学报》2003,(4)
本文在介绍元认知内涵的基础上,通过对元认知在阅读理解和听力理解中作用的分析,阐述了元认知在外语学习中的作用和价值,论证了有效的外语学习离不开元认知策略。文章的结尾作者指出外语教学中应培养学生的元认知能力,教学生学会学习,对其进行终身教育并对此提出建议. 相似文献

专利权作为私权,须明定其权利归属,同一个发明创造只能授予一项专利权,世界通行的做法采先申请原则,对最先提出专利申请的人以优先取得专利的权利,而美国一直以来采先发明原则。但是,受国际专利调和化运动影响,美国国会开始逐步努力转向采先申请原则,此次美国专利法变革即为其最终结果,尽管学界对于此次变革的前途争议不停,但从整体上来说,采先申请原则相较于先发明原则仍有其进步之处。 相似文献

In recent decades significant changes in Nepalese society have greatly contributed to the increase in age at marriage of girls
in Nepal. Factors responsible for these changes include educational development, urbanization and development of mass communications.
However, many parents still marry their daughters at very young ages and this practice is particularly prevalent in the Terai
region. This paper examines several demographic data sets with a view to assessing their utility for understanding the determinants
of early age of marriage of girls in the Terai.
The Nepal Family Health Survey (1996), Nepal Demographic and Health Surveys (2001, 2006), the Nepal Adolescents and Young
Adults Survey (1999) and the 2001 Population Census of Nepal describe changes in at marriage over time. Factors such as sex,
religion, education, geographic region, place of residence (rural/urban), economic status of the household and of women, and
occupation are included in these data sets. However, other factors such as age at menarche, dowry and cost of marriage and
cross-border marriage migration, which have been found to affect the prevalence of the lower age at marriage of girls in the
Terai region, have not been included in the existing demographic surveys. Findings from the current study suggest that these
variables should be included in future demographic surveys. 相似文献

Social background has historically been recognized as a major factor influencing family behavior, though recent work has largely emphasized racial/ethnic influences. Here we use 1994 – 1995 and 2001 – 2002 Add Health data to examine the cohabitation, first marriage, and first birth experience of young women. In a multistate life table context, hypothetical cohorts specified in terms of race and mother’s education are followed, from age 11 to age 24, as they move through 6 family‐related statuses. The results indicate that, for both Black and White women, a higher level of maternal education is generally associated with less cohabitation, less marriage, fewer first births, and a higher percentage of women who experience none of those transitions before age 24. Racial and social background differences are conceptually and empirically distinct. Because mother’s education is associated with substantially different trajectories of early family behavior for both Blacks and Whites, we argue that social background merits increased attention in research on contemporary American family patterns. 相似文献

"土家学"的学科构建是一个重大的问题。"土家学"这一概念,是1997年在《土家学刊》创刊号中首次正式提出来的;构建"土家学"学科的时机,不是绝对的,而是相对的;"土家学"的学科结构,应该允许不同学科结构的并存和共同发展;从今天"土家学"的研究来看,总体上呈现出一种良性的发展态势,当然,客观上也存在一些问题。 相似文献

This paper deals with the study of some probabilistic and statistical properties of a periodic integer-valued diagonal bilinear model. The existence of a periodically strict stationary integer-valued process is shown. Sufficient conditions for the periodically stationary, both in the first and second orders, are established. The closed-forms of the mean and the second moment are obtained. The closed-form of the periodic autocovariance function is established. The Yule–Walker estimations of the underlying parameters are obtained. A simulation study is provided. 相似文献

吕大临是关学研究中的重要人物。通过甄别当前学界关于吕大临生卒年的各种异说,可以得出吕大临生于宋仁宗庆历八年(1048),卒于宋哲宗绍圣元年(1094)。并结合史料对《伊洛渊源录》卷八关于吕大临的《祭文》之作者作出合乎逻辑的考辨。 相似文献

The generalized standard two-sided power (GTSP) distribution was mentioned only in passing by Kotz and van Dorp Beyond Beta, Other Continuous Families of Distributions with Bounded Support and Applications, World Scientific Press, Singapore, 2004. In this paper, we shall further investigate this three-parameter distribution by presenting some novel properties and use its more general form to contrast the chronology of developments of various authors on the two-parameter TSP distribution since its initial introduction. GTSP distributions allow for J-shaped forms of its pdf, whereas TSP distributions are limited to U-shaped and unimodal forms. Hence, GTSP distributions possess the same three distributional shapes as the classical beta distributions. A novel method and algorithm for the indirect elicitation of the two-power parameters of the GTSP distribution is developed. We present a Project Evaluation Review Technique example that utilizes this algorithm and demonstrates the benefit of separate powers for the two branches of activity GTSP distributions for project completion time uncertainty estimation. 相似文献
