  • Internet Discussion Forums: a New Modality for Facilitating Peer Writing in Japanese University-Level EFL Classes
    DOCUMENT RESUME ED 465 299 FL 027 351 AUTHOR Bay, Dale TITLE Internet Discussion Forums: A New Modality for Facilitating Peer Writing in Japanese University-Level EFL Classes. PUB DATE 1999-00-00 NOTE 26p. PUB TYPE Reports Descriptive (141) EDRS PRICE MF01/PCO2 Plus Postage. DESCRIPTORS *Discussion Groups; *English (Second Language); Foreign Countries; Higher Education; *Internet; Second Language Learning; Student Motivation; Teaching Methods; World Wide Web; *Writing Skills IDENTIFIERS Japan ABSTRACT This paper describes unique opportunities offered by the Internet for Japanese college students learning to write in English. It focuses on tasks that students were assigned using discussion forums on the Internet. It begins by describing the Web site, which is <http://www.esljapan.com>, looking at software considerations, privacy issues, operating system compatibility, and the forum. It goes on to examine teaching methods (types of classes and method applied); procedures and problems; teaching points (headline reading, subject line reading, and peer writing); and the Intensive English Programme, which involved diary writing. Using Communicative English Language Test data as a measure of student ability, the study examined whether it was possible to predict that students with greater ability would post more frequently or post more lines to the Web site than students with lower ability. Results found no relationship between test scores and frequency of student postings. The paper recommends considering other factors that might be indicative of student motivation (e.g., their grades being based on how often they posted). (SM) Reproductions supplied by EDRS are the best that can be made from the original document.

  • The Practical Guide to Getting Started with Knovio
    The Practical Guide to Getting Started with Knovio Updated March, 2018 Getting Started with Knovio By Michael Kolowich, Founder/CEO, KnowledgeVision Knovio is an online video platform like no other. It is the most comprehensive platform ever offered for creating, hosting, sharing, organizing, and measuring engagement with rich media content: uploaded video, interactive video presentations, and self-paced presentation “flip decks”. Previous versions of Knovio have already been used by more than 280,000 registered users in 135 countries on six continents. It is in use on more than 1,800 college and university campuses, and more than 300 companies -- in healthcare, financial services, technology, manufacturing, and retail -- have signed annual or multi-year contracts to deploy Knovio in their organizations. This guide, intended for new users, as well as evaluators and reviewers, reveals the full depth of the Knovio platform. It will take you step-by-step through the process of uploading or creating interactive video content, customizing it, publishing it, organizing it into a showcase, adding quizzes and assessments, and measuring viewership right down to the individual viewer level. Armed with a your new Knovio account, we hope you’ll try as many of these exercises as possible.

  • Blog Success Factors: Opportunities for Destination Marketing
    Blog success factors: Opportunities for destination marketing Serena Volo School of Economics and Management Competence Centre in Tourism Management and Tourism Economics (TOMTE) Free University of Bozen-Bolzano, Italy [email protected] Abstract This exploratory study discusses the opportunities for tourism destination marketing organizations to communicate successfully their attractions and offerings through user generated blog content. Key features of effective blogs are identified through netnography of three major blog platforms. Keywords: virtual communities; user-generated content; tourism destination marketing; storytelling; blog, netnography. 1 Introduction Researchers in the fields of consumer psychology, marketing and sociology have paid increasing attention to the value of narrative and storytelling in communicating people’s experiences (Schank & Abelson 1995; Adaval & Wyer, 1998; Escalas 2004). According to Woodside et al. “first-person stories are what people bring back from travels and destination visits” (2007, p. 163) and as Tussyadiah and Fesenmaier state, narration is “a device for interpreting human experience” (2008, p. 301). Narratives and stories about tourism experiences have always been popular. Blogs like traditional journaling are about expressing the inner experiences of travellers and sharing them with others (Conhaim, 2003; Pudliner, 2007; Tussyadiah and Fesenmaier, 2008; Volo & Osti, 2009; van Limburg, 2009). Sharda and Ponnada (2008, p.157) defined blogs as ‘virtual diaries created by individuals and stored on the Web for anyone to access’. Blogs allow travellers to disseminate and investigate ‘vast amounts of information quickly, seeking out the factual, the real and the truth’ (Pudliner, 2007, p. 47). Blogs combine texts, images, videos, audios, links and a collection of tools to share commentaries or news while travelling (Leu et al., 2005).

  • Composing Digital Community Spaces: Design and Literacy Practices In/Of the Archive
    1 COMPOSING DIGITAL COMMUNITY SPACES: DESIGN AND LITERACY PRACTICES IN/OF THE ARCHIVE A dissertation presented by Kristi Tillene Nadira Girdharry to The Department of English In partial fulfillment of the requirements for the degree of Doctor of Philosophy in the field of English Northeastern University Boston, Massachusetts August, 2016 2 COMPOSING DIGITAL COMMUNITY SPACES: DESIGN AND LITERACY PRACTICES IN/OF THE ARCHIVE by Kristi Tillene Nadira Girdharry ABSTRACT OF DISSERTATION Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in English in the College of Social Sciences and Humanities of Northeastern University August, 2016 3 ABSTRACT This dissertation offers a case study of Our Marathon: The Boston Bombing Digital Archive & WBUR Oral History Project by exploring the relationships between the creation of the archive, the use of the archive, and the narratives the archive tells on its surface and in its stories. More specifically, it looks at how Our Marathon adheres to/departs from traditional archives through its state as a digital archive, its attempt to both historicize and memorialize an event, and its focus as a community project. This dissertation takes advantage of offering a real-time examination of the digital archive’s role in capturing the artifacts and reflective practices of people affected by the tragic events of the Boston Marathon bombings through a mixed-methods approach; it draws upon primary research, the archive itself, and the researcher’s own participation in designing and building the space. To add to ongoing conversations on digital archives in Rhetoric and Composition scholarship, because of the complicated nature of the term “community” and because of a gap in understanding how these types of digital community sites function in the world, this dissertation aims to open up a conversation on building spaces for public writing and how the sponsors of these spaces impact participation and representation.

  • Anti-Spam Methods
    INTRODUCTION Spamming is flooding the Internet with many copies of the same message, in an attempt to force the message on people who would not otherwise choose to receive it. Most spam is commercial advertising, often for dubious products, get-rich-quick schemes, or quasi- legal services. Spam costs the sender very little to send -- most of the costs are paid for by the recipient or the carriers rather than by the sender. There are two main types of spam, and they have different effects on Internet users. Cancellable Usenet spam is a single message sent to 20 or more Usenet newsgroups. (Through long experience, Usenet users have found that any message posted to so many newsgroups is often not relevant to most or all of them.) Usenet spam is aimed at "lurkers", people who read newsgroups but rarely or never post and give their address away. Usenet spam robs users of the utility of the newsgroups by overwhelming them with a barrage of advertising or other irrelevant posts. Furthermore, Usenet spam subverts the ability of system administrators and owners to manage the topics they accept on their systems. Email spam targets individual users with direct mail messages. Email spam lists are often created by scanning Usenet postings, stealing Internet mailing lists, or searching the Web for addresses. Email spams typically cost users money out-of-pocket to receive. Many people - anyone with measured phone service - read or receive their mail while the meter is running, so to speak. Spam costs them additional money. On top of that, it costs money for ISPs and online services to transmit spam, and these costs are transmitted directly to subscribers.
