网络环境下影响大学生英语写作教学因素的调查与分析

在为期一年的日常实践教学的基础上通过问卷调查的方式了解影响我校非英语专业学生在网络环境下发展英语写作能力的各种因素。调查结果显示,绝大部分学生承认网络写作模式具有传统写作模式不可替代的各种优势,但对通过网络写作模式更有效的提高写作能力没有足够的信心。调查发现,整体语言水平低是阻碍网上英语写作教学顺利实施的最重要的因素,其次是技术因素,最后,由于语言水平和技术条件的障碍所导致的心理障碍也是不容忽视的因素之一。鉴于以上实际情况,作者建议设计一套适合我校以及与我校有相同校情的西南地区各高校的阶梯式网上写作模式,以充分发挥现代网络技术的各种优势,实现写作教学改革的新突破。     

中国早期电影《新女性》与民国上海的女性话语建构

《新女性》这部影片于1935年春节之际上映,其女主角的原型是自杀的"作家明星"艾霞,而扮演女主角的阮玲玉又在影片上映后不久像影片里那样服安眠药自杀。这部影片台前幕后的种种故事、讨论和纠纷在民国时期的上海形成了一个轰动性的事件。通过比较分析艾霞的生平、电影剧本和报刊评论,我们可以看出各种媒体在此共同参与了一场"新女性"的讨论和建构,从中演绎出那个时代的妇女问题、性别想象和社会政治的变迁。     

Longitudinal patterns of emerging literacy in beginning deaf and hearing readers

The emerging reading and spelling abilities of 24 deaf and 23 hearing beginning readers were followed over 2 years. The deaf children varied in their language backgrounds and preferred mode of communication. All children were given a range of literacy, cognitive and language-based tasks every 12 months. Deaf and hearing children made similar progress in literacy in the beginning stages of reading development and then their trajectories began to diverge. The longitudinal correlates of beginning reading in the deaf children were earlier vocabulary, letter-sound knowledge, and speechreading. Earlier phonological awareness was not a longitudinal correlate of reading ability once earlier reading levels were controlled. Only letter name knowledge was longitudinally related to spelling ability. Speechreading was also a strong longitudinal correlate of reading and spelling in the hearing children. The findings suggested that deaf and hearing children utilize slightly different reading strategies over the first 2 years of schooling.     

Stability in Mother-Child Interactions from Infancy through Adolescence

OBJECTIVE: The current study examines homotypic stability in mother-child interactions, applying similar rating scales of mother-child interactions at 1 and 4.5 years, and heterotypic stability from 1 to 13 years and 4.5 to 13 years, using conceptually similar but not identical rating scales at age 13. DESIGN: We coded videotaped mother-child interactions in 202 families when children were 1, 4.5, and 13 years of age during age-appropriate and developmentally salient structured tasks for relationship quality. RESULTS: Multiple regression analyses controlled for the effects of child birth order and gender as well as maternal age and education. Maternal and dyadic, but not child, mother-child interaction qualities at 1 year significantly predicted similar or equivalent constructs at 4.5 and 13 years. Heterotypic stability from 1 to 13 years was partially or fully mediated by the same constructs at 4.5 years. CONCLUSIONS: Maternal behaviors showed a pattern of homotypic and heterotypic stability, whereas dyadic behaviors were somewhat less stable. Child behaviors showed evidence of both homotypic and heterotypic instability.     

高中物理学习困难的成因分析及对策研究

物理难学,这似乎已成为高中学生的共识。笔者经过大量调查研究发现造成这种状况的原因很多,单就学的方面而言,大多数同学主要是由于怕学、厌学或不会学物理。调查结果显示,物理学习困难的学生,在进入高中前就对物理学习心存惧怕,其中有30%左右的同学,一遇到困难就轻言放弃;另有50%左右的同学对物理学习虽也信心不足,但一开始还是下定决心要学好物理,他们在物理学习上化了大量时间、精力,不可谓不刻苦,不能说没努力,但由于缺乏兴趣,学习物理对他们来说是一种被迫行为,体会不到学习中的乐趣,时间一长,必然觉得学习枯燥无味,变成了一种苦差事,…

Investing in the renewal of urban science teaching

This article provides a conceptual framework for understanding what is involved in improving urban science teaching and what might be implied by conducting research on its improvement. It is argued in this article that three sets of forces and conditions have a direct impact on urban science classrooms: first, the array of interdependent policies at school, district, and state levels about science teaching in particular and about education improvement more broadly construed; next, the investment and use of instructionally relevant resources at each of the three levels and their differing impacts on the renewal of urban science teaching; and finally, the broader context in which urban science teaching occurs mediating how these resources are—or can be—used. Mediating factors include the professional peer community, subject‐specific instructional leadership, the professional development infrastructure, the supply of available science teachers, and the broader community context. The article concludes with suggestions for how this framework informs directions for future research on the promise and limits of efforts to renew science teaching in urban settings. © 2001 John Wiley & Sons, Inc.

Student counselling in Australian universities: Forty years of development

Since the first development of counselling services in Australian universities in 1953, the tertiary system, and counselling services within them, have undergone a forty-year period of growth and change, and now all universities have counselling services which typically focus on short-term counselling interventions and are characterised by high levels of professionalism. Two case studies provide a picture of the situation in Australian universities. One case is that of an older and larger institution recently formed as a multi-campus university by amalgamations and with its main campus in the inner city of Australia's second-largest city. The contrasting case is of a newer, suburban university in one of the smaller capital cities. The challenges facing university counselling services in the future include the continuing pressure for greater accountability, the increasing demands of a multi-cultural clientele, the temptation to take on a wider range of tasks than can be sustained, and its obverse, the risk of over-specialisation.
