Government agencies are directed to communicate objective and scientific information to the public, but studies show that political ideology may play a role in how much information governments provide. In this paper I argue that the ideology of a head administrator, and its alignment with agency mission, can restrict the kinds of information that government agencies provide, which may or may not amount to a type of regulatory capture. This impact may also be moderated by the specific media in which the communication takes place. I explore this theory via a case study of the United States Environmental Protection Agency online communication over a period of 32 months, during the years of 2013–2014, under the Democratic Administrator Gina McCarthy, and 2017–2018, under the Republican Administrator Scott Pruitt, via topical terms and document analyses of Twitter posts and web news releases. The information—topics, policies and issues—remain largely consistent across administrations and media channels, but notable distinctions are observed that point to the political ideologies of administrators in office, including a restriction of relevant scientific information on climate change during the misaligned administrator. Moreover, results show differences across media types which may reflect speed and popularity affordances of Twitter compared to website communication. I conclude by discussing the importance of policies to protect against ideological partisanship, and how social media may be better used as tools in government information policy and online communication.  相似文献

This paper reports on a case study of an online pre-service teacher education course in a New Zealand university aimed at exploring the potential of student-generated podcasts as a form of interactive formative assessment at a distance. The study was part of a wider two-year funded project with the overall goal of documenting, developing, and disseminating effective and innovative e-learning practice. Findings from lecturer and tutor interviews, student focus group (FG) discussion, and course evaluations indicate that the podcasting task provided opportunities for the course lecturer, tutors, and students to learn and share ideas with one another. The experience empowered students to develop the skills and confidence to initiate more independent inquiry into technologies to support their pedagogical purposes. The study contributes to a better understanding of the skills, dispositions, and knowledge needed to prepare teacher candidates for teaching-learning contexts where information and communication technologies are increasingly pivotal.  相似文献

对大部分人来说,当我们讨论学习时,我们会不可避免地将其与正规的教育系统联系起来。但任何关于ICTs在儿童学习中角色的研究都使我们认识到,在校外情景中,儿童非常容易沉浸于ICTs相关的活动中,这就迫使我们必须用更广阔的视角来审视包括学校、家庭、休闲、图书馆、博物馆等在内的"教育生态学"。本综述首先对"非正规学习"进行了界定,指发生在学校环境之外,数字技术支持或与数字技术交互的非正规学习;接着讨论了本研究所依据的学习的核心理论以及在ICTs支持的关于学习的研究中不断产生的新的学习理论;勾勒出儿童在校外获取和使用数字技术的情景;然后基于已有的关于技术支持的非正规学习的案例,总结提炼出技术支持的非正规学习的关键特征;最后对这些研究的理论和政策含义进行了深入的研究和剖析。  相似文献

Information and communication technologies (ICTs) have become ubiquitous in most people’s lives. Yet, within the developing and emerging regions, there are still many who have not fully benefitted from ICTs. This article reports on a research project that focused on investigating the barriers, opportunities and impact that ICTs have on the teaching and learning of mathematics in South African schools. A quantitative research methodology in the form of a survey was used to assess South African mathematics teachers’ access to and use of ICTs and mobile technologies. A literature study revealed that there were universal barriers (i.e. lack of access to resources, time, effective training, confidence; resistance to change and negative attitudes; and no perception of benefits) and numerous opportunities for using ICTs in teaching and learning in general, and in subjects such as mathematics and science, in particular. The survey findings suggested increased deployment of ICT resources; introduction of more ICT training opportunities for teachers and students; and the firm adoption of ICT policies and directives within the education domain.  相似文献

ABSTRACT

The expectation in education today is that pre-service teachers should graduate from teacher education adequately prepared to teach with Information Communication Technologies (ICTs) that have potential to enhance curriculum delivery, hence improving quality of education. However, research shows that pre-service teachers are graduating from teacher education underequipped to teach with ICTs. The aim of this study is to understand why, given the deployment of ICTs for teaching and learning in teacher education, the new teachers remain underprepared to teach with ICTs. Qualitative research approach was employed in this study, whereby randomly selected pre-service teachers were interview respondents. Written reflections on their preparation to teach with ICTs also formed part of the data collected. Technological Pedagogical and Content Knowledge (TPACK) theory was embraced to guide the study. Analysis of the data shows that the main contributing factor of the new teachers’ under-preparedness to teach using ICTs is the quality of instruction they receive during their training.  相似文献

This article reviews the body of research on the use and role of instant messaging (IM) in campus life, and how IM is a key part of university students' communication. IM is a synchronous form of communication, and its speed, availability information, and support for multiple conversations have made it appealing for young people. With university students, in particular, showing a heavy reliance on IM, researchers have shown great interest in how university students use IM and how it is integrated in their social and academic life. While studies are emerging in various disciplines, no attempt has been made to integrate the disparate findings and approaches. This article synthesizes key findings, provides a map of the literature, and discusses conceptual problems inherent in the study of IM and other information and communication technologies (ICTs) that will help researchers identify key areas of study and opportunities for future investigation.  相似文献

海外社区信息学的专业教育与研究现状   总被引:1,自引:0,他引:1  
社区信息学是研究利用信息与通讯技术(ICTs)促进社区发展的相关问题的学科。自20世纪90年代末成为一个独立的研究领域,社区信息学在世界各地,尤其是在发展中国家弱势社区的社会经济发展支持方面得到广泛应用。随着实践案例积累的日益丰富,社区信息学的教育和研究不断发展,从专业教育、专著、期刊及机构网站等方面,可看到其学科建设正在逐步完善。  相似文献
