  • Fostering Information Literacies in a Writing Course
    Canadian Journal for Studies in Discourse and Writing/Rédactologie 51 Volume 29, 2019 http://journals.sfu.ca/cjsdw Article Learner-Created Podcasts: Fostering Information Literacies in a Writing Course Stephanie Bell York University Abstract This paper describes an experimental learner-created podcasting assignment in a first-year undergraduate research skills course for professional writers. The podcasting assignment serves as a contextualized experiential writing project that invites students to refine their research skills by participating in the invention of an emerging genre of radio storytelling. The power of the podcast assignment lies in the liminal space it creates for learners. It moves students beyond familiar and regimented essay conventions to an unstable writing environment where digital tools for producing, publishing, and negotiating meaning offer a range of possible audiences, modalities, forms, and modes of meaning making. This space creates the pedagogical conditions for epistemic development, through which students adopt as their own the research practices of adept and experienced writers. The multiple demands of this course on writing, research, and digital environments generates the beginnings of interdisciplinary writing pedagogy involving Kent’s (1993, 1999) postprocess mindset, the ACRL’s (2015) Framework for Information Literacy in Higher Education, Baxter Magolda’s (1999) constructive-developmental pedagogy, and Arroyo (2013)’s elaboration of participatory digital writing pedagogy.

  • Information Transliteracy”?
    International Conference “Media and Information Literacy (MIL) for Knowledge Societies”, 24-28 June, 2012, Moscow, Russian Federation Can one speak of an “information transliteracy”? Vincent LIQUETE ( Bordeaux University – IMS/CNRS UMR 5218 [Human Engineering and Knowledge Engineering (Team CIH)] [email protected] / [email protected] Summary of paper: The issue of transliteracy in general and particularly informational transliteracy is increasingly being debated worldwide and from extremely varying perspectives. These concepts refer to highly varied cultural and professional realities and contexts. In this paper we will discuss three dimensions and issues. First, we will attempt to delineate the scope and range of current thinking by researchers in information and communication sciences in France with regard to informational transliteracy, and present its four main components. Second, we will lay the claim that the informational transliteracy approach goes beyond the “Media and Information Literacies (MIL)” approach, in particular by giving all due importance to issues related to learning with computers, i. e. “computation”. Finally, we will present some new thinking that is currently being implemented in the French education system and will present some research projects involving informational transliteracy (LIMIN-R project, Translit project, etc.). Key words: Transliteracy / Information culture / French educative system / Informational practice /Competencie / Forward For twenty years now, the notions of information literacy and thereafter Translitteracy have been the subject of a wide range of definitions and an extensive scientific literature, especially in the Anglo-Saxon world. We will attempt during this presentation to demonstrate some of the main dimensions in terms of skills and attitudes in the various literacies that are giving rise to the new forms of training and support required in the future.

  • Adapting Reading Intervention for Online Students
    Adapting reading intervention for online students Baiyun Chen Atsusi Hirumi University of Central Florida Background Information With the advances of computer and network technologies, student enrollment in distance education has increased rapidly since the 1990’s. In 2003, it is estimated that about 40,000 to 50,000 K-12 students are enrolled in online courses nationwide (Golden, Wicks, & Williams, 2004). With the ever-increasing number of K-12 students who attend online program, researchers state in a report on virtual school in United States that “online education program(s) … already are having a significant impact on public education” (Watson, Winograd, & Kalmon, May 2004). Most likely, the K-12 online programs will take an increasingly important role in the school system of the United States. According to Building a Snapshot of Virtual Schools Across the Nation by Collins, “12 states have established online high school programs and 5 others are developing them… 25 states allow for the creation of so- called cyber charter schools, and 32 states have e-learning initiatives under way” (Collins, 2004). In the future, the option of e-learning will be available to every child for purposes of advanced study, credit recovery or remedial learning. The target population of a virtual school encompasses gifted students, students seeking credit recovery, and at-risk and dropout students. The focus of this paper is the problematic students who do not succeed in traditional classroom. The at-risk and dropout student population size is shockingly large. In 2000, some 3.8 million young adults were out of school without a high school credential, accounting for 11% of 16- to 24-year-olds in the United States (Kaufman, Alt, & MPR Associates, 2001).

As we celebrate the 100th anniversary of women’s right to vote in the United States, we also must acknowledge that the 19th Amendment’s passage was just one victory in a much larger and ongoing political struggle for women and other marginalized peoples demanding their democratic rights. “MUSE in Focus: Commemorating the 19th Amendment” is a curated selection of content from Project MUSE’s publishing partners and offers a broad range of perspectives about the history of the women’s suffrage movement in the US and its continued relevance to the ongoing struggle for true democracy around the globe.

  • Chapter 2 EXPLOSIVES
    Chapter 2 EXPLOSIVES This chapter classifies commercial blasting compounds according to their explosive class and type. Initiating devices are listed and described as well. Military explosives are treated separately. The ingredi- ents and more significant properties of each explosive are tabulated and briefly discussed. Data are sum- marized from various handbooks, textbooks, and manufacturers’ technical data sheets. THEORY OF EXPLOSIVES In general, an explosive has four basic characteristics: (1) It is a chemical compound or mixture ignited by heat, shock, impact, friction, or a combination of these conditions; (2) Upon ignition, it decom- poses rapidly in a detonation; (3) There is a rapid release of heat and large quantities of high-pressure gases that expand rapidly with sufficient force to overcome confining forces; and (4) The energy released by the detonation of explosives produces four basic effects; (a) rock fragmentation; (b) rock displacement; (c) ground vibration; and (d) air blast. A general theory of explosives is that the detonation of the explosives charge causes a high-velocity shock wave and a tremendous release of gas. The shock wave cracks and crushes the rock near the explosives and creates thousands of cracks in the rock. These cracks are then filled with the expanding gases. The gases continue to fill and expand the cracks until the gas pressure is too weak to expand the cracks any further, or are vented from the rock. The ingredients in explosives manufactured are classified as: Explosive bases. An explosive base is a solid or a liquid which, upon application or heat or shock, breaks down very rapidly into gaseous products, with an accompanying release of heat energy.
