分久必合——论国际视野下的高中文理分科

高中是否应该取消文理分科是目前社会各界关注的一个热点。然而取消文理分科并不能解决学生的全面发展问题,因此,我们必须寻找一条既能培养全才,又能选拔专才的全新道路,尽管在实际上这两者很难同时兼顾,但我们不能不努力探索。     

对农村教师缺乏与素质提升的多维探讨

根据《国家中长期教育改革和发展规划纲要》,困惑农村义务教育的问题是教师缺乏与教师素质亟待提升。要解决这两方面的问题,应强化政府的投入责任,给予农村教育政策优惠或倾斜,并动员全社会都成为农村教育的出资人;科学规划、调整农村教育布局,调整学期教学计划,试行农村中小学三学期制;推进和完善对农村中小学的支教、帮教活动,组织城市退休教师到农村支教、帮教;像选村官一样,由国家和地方政府制定优惠政策,吸收和选拔优秀大中专毕业生到农村中小学任教;健全培训、轮训、互访制度,使农村教师的继续教育经常化、规范化;建立教育信息网络平台,实现城乡教育资源的共享。     

试析机电一体化复合人才与自组织教学

培养应用型复合人才是目前高职教育实施的重要举措之一。当代机电一体化复合人才不仅要掌握相关的专业知识和技能,还应该具备较高的管理素质、熟悉企业业务外包和敢于创新和创业。要实现这个目标,就必须改革现有的教学模式,用自组织理论指导教学实践。     

新闻专业古代文学教学方法探析

在广播电视新闻专业中,<古代文学作品选>是一门具有集约特征的理论基础课,它兼有两种教育功能,即以提高人才的文化底蕴和整体素养为主的无形教育功能和以训练人才的认知、判断、表达、创造等实务能力为主的有形教育功能.为解决这门课课时少、相关配套知识欠缺等问题,在教学中,应运用拓展法、入境法、艺术归纳法、开放评价法、吟诵法等操作性强的教学技法,以培养集广博、精深、多能于一身的现代复合型传媒人才.     

用“三深入”求得“三贴近”

“三贴近”中的实际是根基,生活是源泉,群众是出发点和落脚点,本质和核心就是密切联系群众.新闻战线推行“三深入”,实际就是践行“三贴近”的具体表现,是新闻工作者接地气、长灵气、出生气的一个过程,也是感受时代脉动、吮吸生活醇香、倾听群众心声的极佳途径.新闻工作者只有坚持到基层采访、观察,转作风、改文风,才能求得“三贴近”.     

高职高专英语教学现状探讨

高职院校教育目的是为国家和社会培养有文化素质的具有专业技术的劳动者,掌握英语是培养有文化素质人才的一个重要方面。随着改革开放的进一步的发展,中国与世界的接触越来越密切,高素质劳动者的英语学习显得越来越重要。但目前高职高专学生在英语学习中存在很多问题。笔者针对这些问题提出了一些相应的措施,希望对高职高专综合英语教学有所裨益。     

近代回族报人丁竹园的职业观及其社会实践研究

丁竹园是近代回族社会早期重要报人的代表,他主张白话办报、为民办报,言论自由办报。他身体力行,撰文立说,发表演说,创办刊物,积极投入到社会实践当中,是近代回族社会杰出的回族爱国知识分子。通过对丁竹园生平活动、办报职业观、社会实践及其社会影响等几个方面,来评述他的先进事迹。     

基于报人视角的张恨水研究的若干问题

张恨水是一位有深远影响的小说家,更是一位资深报人。从报人视角对张恨水进行关注,不但具有丰富的内容可进行探讨、挖掘、研究、总结,而且具有重要的理论价值和现实意义。然而,目前有关这方面的研究状况并不令人满意,亟待深入和加强。随着文化产业和交叉学科的发展,综合研究、跨学科研究、交叉研究已经成为可能,在这样的背景下,从报人角度和编辑视域关注张恨水、解读张恨水、研究张恨水将是一个极为广阔的空间。     

REPORTING ON FAIRNESS IN CIVIC LIFE

Drawing on procedural justice research from social psychology, this study explores the role that journalistic practice plays in telling community members about whether local politicians are behaving fairly. Qualitative interviews with 24 community journalists working in cities in Upstate New York are used to answer the following research questions: (1) how does content regarding authority fairness find its way into news stories, and (2) what facets of justice—whether distributive, voice, or relational—do journalists emphasize. The interviewed journalists said that they often used their evaluation of local politicians’ fairness in deciding whether to pursue a story. In doing so, these journalists highlighted questions of whether politicians were listening to community members and the degree to which they appeared to take the best interest of citizens to heart. There was little agreement among journalists about the degree to which citizens could adequately make fairness judgments based on local news coverage, although the television reporters believed that television's visual component provided key information about the fairness of local politicians.     

A fast and versatile cross-linking strategy via o-phthalaldehyde condensation for mechanically strengthened and functional hydrogels

Fast and catalyst-free cross-linking strategy is of great significance for construction of covalently cross-linked hydrogels. Here, we report the condensation reaction between o-phthalaldehyde (OPA) and N-nucleophiles (primary amine, hydrazide and aminooxy) for hydrogel formation for the first time. When four-arm poly(ethylene glycol) (4aPEG) capped with OPA was mixed with various N-nucleophile-terminated 4aPEG as building blocks, hydrogels were formed with superfast gelation rate, higher mechanical strength and markedly lower critical gelation concentrations, compared to benzaldehyde-based counterparts. Small molecule model reactions indicate the key to these cross-links is the fast formation of heterocycle phthalimidine product or isoindole (bis)hemiaminal intermediates, depending on the N-nucleophiles. The second-order rate constant for the formation of phthalimidine linkage (4.3 M⁻¹ s⁻¹) is over 3000 times and 200 times higher than those for acylhydrazone and oxime formation from benzaldehyde, respectively, and comparable to many cycloaddition click reactions. Based on the versatile OPA chemistry, various hydrogels can be readily prepared from naturally derived polysaccharides, proteins or synthetic polymers without complicated chemical modification. Moreover, biofunctionality is facilely imparted to the hydrogels by introducing amine-bearing peptides via the reaction between OPA and amino group.
