改革开放40年我国中小学教材建设的成就、问题与应对     

石鸥  张文 《课程.教材.教法》2018,(2):18-24

改革开放40年来,中小学教材建设取得了突出的成就。中国特色的教材管理体制基本形成,教材多样化的格局初见成效,教材立体化的体系初步构建,教材质量逐步提高,社会资源广泛参与教材建设,教材研究日益被重视。但需要高度关注的问题有:数字教材的管理与研究,国际学校教材的监管,对港澳台地区教材的关注,少数民族教材建设等。笔者认为,应该成立教材第三方评价机构,加强少数民族教材的开发与研究,建立和完善数字教材的管理规范,完善和落实对国际学校的课程与教材的监管制度,筹建教材资源中心和研究基地。  相似文献   

高校教师视角下的人文社会科学国际发表及其激励制度     

许心  蒋凯 《高等教育研究》2018,(1):43-55

在学术国际化和中国哲学社会科学"走出去"的背景下,越来越多的高校对教师发表SSCI和A&HCI论文进行激励。激励制度主要体现在物质奖励和学术评价两个层面。从对国内某研究型大学文科教师深度访谈的情况来看,高校教师对人文社会科学国际发表及其激励制度持不同意见,虽一般不反对对国际发表进行物质奖励,但他们对国际发表在学术评价中的地位的认识存在较大分歧。高校在实施人文社会科学国际发表激励制度的过程中应理解和尊重差异性的存在,关注国际化与本土化的平衡。  相似文献   

Disciplined freedom,branded authenticity,and dependable independence: how tensions enact flexibility in lifestyle blogging careers     

Ziyu Long  Elizabeth D. Wilhoit 《Journal of Applied Communication Research》2018,46(3):368-387

Analyzing 219 blog posts from 52 self-employed women lifestyle bloggers in North America, this study shows how these digital professionals navigate tensions and communicatively constitute work flexibility. In their narratives, women bloggers employed tension management approaches such as reframing, continual connections, and reflective practice in response to tensions in enacting temporal–spatial, identity, and financial flexibility. Specifically, women followed oxymoronic constructions – disciplined freedom, branded authenticity, and dependable independence – to embrace and transform competing poles of fluidity?structure, authenticity?marketability, and independence?interconnection. Expanding work–life research to the self-employed digital labor context, this study responds to recent calls to uncover more-than tension management strategies in empirical settings and contributes to a tension-centered, contextual, and processual analysis of workplace flexibility construction.  相似文献   

Technological capital: an alternative to the digital divide     

Andrew Carlson  Alyssa M. Isaacs 《Journal of Applied Communication Research》2018,46(2):243-265

This paper identifies individuals’ accumulated history with Information and Communication Technologies (ICTs) as a replacement for the contested and outdated term ‘digital divide.’ We propose that an individual’s ability to benefit from their technological history consists of four factors: awareness, knowledge, access, and technological capacity of the user’s social collective. Together, these factors make up the individual’s level or amount of Technological Capital. The development of this construct was based on empirical research conducted in Soweto, South Africa, and through an analysis of the literature on assessing individuals’ accumulated histories. The concept of technological capital has the potential for application in fields in which ICTs are used for communication, capacity building, and identifying barriers to adoption of new technologies. The use of the concept may have implications for policy decisions, resource allocation, and future research into differences among individuals’ and communities’ ability to benefit from the introduction of new technologies.  相似文献

历史地理信息的获取与标准化——以上海交通大学馆藏地方历史文献为例     

汤萌  李芳  王昕 《图书馆杂志》2018,(1):50-57

上海交通大学图书馆针对近年来收集的地方历史文献开展了数字化加工工作。如何有效地提取文献蕴含的地理信息并使其标准化,最终实现数字化的展示、利用与分析是工作的难点之一。地理信息经由人工获取,根据研究需求按照分段揭示的原则著录到地域相关的元数据字段中。基于可统计的文献来源,分布集中的文献优先编写代码转换规则,可机读代码避免了语义识别等程序的繁冗。鉴于明清时期行政区划的特点,代码采用"省-县-都-图-村"五级格式,遵照标准化、兼容性、求同性与扩展性的编制原则,以期实现文献关联聚类、信息自动获取与空间可视化等数据化效果,还原地域视角下的历史原貌。  相似文献

Religiosity and the digital divide in Canada     

Maryam Dilmaghani 《The Communication Review》2018,21(3):181-211

The digital divide refers to the differential patterns of Internet access adoption and usage across different segments of populations. The digital divide has been linked to demographic variables such as age and gender, and socioeconomic characteristics such as education and income. Using a nationally representative Canadian survey (N = 27,223) conducted in 2013, this paper investigates whether religiosity has an independent effect on the digital divide, accounting for the previously validated predictors of Internet use. Religiosity is found to negatively associate with Internet access and activity, controlling for a large set of characteristics such as age, ethnicity, education, and income. The religiosity-related gaps in the usage patterns appear to indicate lifestyle differences for those without any tie with religion compared with the individuals of average religiosity. For the very religious, the gaps indicate that they utilize the Internet for social networking less than others. Various implications are discussed.  相似文献
