TSA: Privacy - 0 views

  • The officer who views the image is remotely located in a secure resolution room and never sees the passenger.
  • To further protect passenger privacy, millimeter wave technology blurs all facial features and backscatter technology has an algorithm applied to the entire image.
  • Advanced imaging technology cannot store, print, transmit or save the image, and the image is automatically deleted from the system after it is cleared by the remotely located security officer. Officers evaluating images are not permitted to take cameras, cell phones or photo-enabled devices into the resolution room.

  • TSA recently new software on all millimeter wave imaging technology machines – upgrades designed to enhance privacy by eliminating passenger-specific images and instead auto-detecting potential threats and indicating their location on a generic outline of a person.
  • For units that do not yet have the new software, TSA has taken all efforts to ensure passenger privacy. To that end, the officer who assists the passenger never sees the image the technology produces and the officer who views the image is remotely located in a secure resolution room and never sees the passenger. The two officers communicate via wireless headset.

Video: Voices From the Front Lines of Online Learning - Wired Campus - The Chronicle of... - 0 views

  • As a first time student enrolled in an online course, I am dismayed by the total lack of the instructor's input. She merely feeds us the publisher's materials, has a teaching assistant grade the homework and pulls her tests from the publisher's test bank. I could teach this course, easily, myself.
  • There is no "teaching" or explanation, just self study. Silly things are graded like participation in discussions, and homework is often graded despite the fact the solutions manuals are all available online for students. Many online courses are taught by for-profit schools whose key motivation is to never fail students and to keep their tuition dollars flowing in. Even traditional schools' online courses are silly. The teacher has no way to know who is taking the exams. Exams are open book. Let's all start calling it the sham that it really is.
  • I have to say, from my experience as a student in an Ivy League school on the ground I had experiences like that. You can't judge an entire way of teaching and learning from these experiences.I have been teaching graduate school online since 1999. I engage actively with learners one on one, in small groups and in the class. I use meeting technologies as well as the Blackboard discussion. Learners work independently or collaboratively, depending on the assignment. I review and make detailed comments on their writing in assignments that require them to reasearch and draw on multiple scholarly sources. There is typically not one textbook, so "publisher's materials" or "open book exams" are non-existent. Even discussion assignments are submitted in full APA style and require references to the assigned and other scholarly readings. Higher order critical and creative thinking, original analysis, are required.

  • When these learners complete the program, they have competencies relevant to 21c life-- they can communicate, collaborate, access and integrate information from diverse sources using electronic libraries. It is an exciting way to teach and learn and it is the wave of the future so we need to gain the skills needed to make these educational experiences consistently meaningful.
  • Working with online instruction requires different techniques. An instructor online cannot usually look at a student's face and see that she isn't grasping the point, for example, or when she has fallen asleep. I can see why instructors would miss this type of face-to-face communication; online feedback is both less immediate and in some cases more direct. But a lecture can be truly engaging or enormously incomprehensible even for the student who moves to the front row to try to understand it all. Online learning can also reap huge results or can suffer from another set of equally mind-numbing problems.
  • I have to agree with jsalmons and bghansel. It's not the fact that a school is online or on-ground that matters. It's the quality of the educator that matters. I, too, have gone to and taught in Ivy League schools and found them to be a mixed bag, just as I've found online schools to be a mixed bag.
  • Yes, softshellcrab, discussion questions are the backbone of online courses. Are you telling me they don't play a role in on-ground education? Are you telling me that only talking-head lectures educate? Is there something wrong with students doing self-studying? Haven't you seen lecture content in online courses? I'm puzzled as to why you think critical thinking, Socratic reasoning/questioning, and constructivism are bad or can't be done online, but can on-ground.
  • The most (Stress THE MOST)primary issue with distance education is the degree of affective education taught.
  • We can use SKYPE, WIMBA or other "video" based education, but what we lose is the subtle differences of students and their interactions with others that makes it difficult to determine their level of character (highest level of affect).
  • Bill Gates may think we will have less seated instruction in the future (see another Chronicle issue elsewhere), but the backlash against online will be in the form of those who cannot interact and thus not obtain jobs (except in the places where it wont matter because none have any affect in that place).The bottom line is that we are losing a major portion of our education system in a pure online education format. Until we recognize how to better teach affective education with online, and more importantly assess that type of education, we will have major issues not only in higher education, but also in industry/business.And this is an open invitation for Bill Gates to discuss this issue.
  • "Quality on-line teaching is harder than regular classroom teaching, but poor on-line teaching is easier than regular classroom teaching."
  • But can I make it more specific - "Quality on-line teaching is harder (taking more time, e.g.)than regular classroom teaching of the same quality (in achieving the same extent of satisfaction in students, e.g.)?"
  • However, no one has mentioned the preparation required for quality online instruction. Some building blocks of good online programs are high quality/targeted content, flexible tools for development and delivery, engaging and interactive design, attentive and responsive instructors during the class, self motivated learners, and as always outcomes-based curriculum.

Modeling Social Media in Groups, Communities, and Networks - 0 views

  • the evolution of what was initially a group into a community of practice is illustrated, as well as how social media enables one CoP to interact with others to become part of a distributed learning network. Participants in the networked communities continually leverage each other’s professional development, and what is modeled and practiced in transactions there is applied later in their teaching practices
  • Teachers can be shown how to use social media, but unless they use it themselves they are unlikely to change their practices. There is evidence that teachers trained in programs where their instructors used social media (modeled it) are more comfortable with technology than if their instructors did not themselves use these tools. This article suggests how teachers can interact with numerous communities of practice and distributed learning networks where other participants are modeling to and learning from one another optimal ways of using social media in teaching. This strongly suggests that teachers must be trained not only in the use of social media, but through its use.

      "Through its use" is key here!
  • “To teach is to model and demonstrate. To learn is to practice and reflect.”

  • Networks are ideal as enhancements for all four of these essential activities of lifelong learners, and they enable us to model, demonstrate, practice, and reflect constantly and effectively.
  • “teachers who practice autonomy in their own professional development formulate heuristics for harvesting knowledge within their personal learning spaces, and thus stand a better chance of inculcating the desired behaviors in their students, thus increasing the likelihood of producing potentially autonomous and lifelong learners. But it is a percolative process.
  • The wiki allowed anyone (anyone could write on it, not just Webheads) to leave an email address if they needed an invitation, and those who had spare invitations would give one to someone in need. The system worked to organize a quick and robust Webheads Wave, a sandbox for teachers to try out the tool and to model and demonstrate and practice with one another.
  • Networks provide the framework for this to happen.
  • Pedagogy
  • Networking
  • Literacy
  • Paradigm shift results when many people in a community or network follow the same process of seeing things modeled and demonstrated for one another in such a way that after considered reflection and weighing of the old and new ways of addressing a problem, they gradually alter their practice.

  • multiliteracies approaches
  • When the Writing for Webheads group of students and teachers formed in 1998, participants were distrustful of sending their pictures to strangers on the Internet, and even to reveal their real names.
  • Photographs and voice/webcam communications enable group members to see the human behind the text message and enhance bonds leading to a sense of community
  • Scaffolding one another’s practice by modeling to one another and answering each other’s questions
  • the evolution of social media has enabled the Webheads CoP to interact with others to become part of a much wider distributed learning network.
  • Siemens has long espoused the notion of connectivism, famously summarized as “The pipe is more important than the content within the pipe.” (Siemens, 2004, n.p.). Here, Siemens means that it is more important to nurture a system of connections between knowledgeable people (the pipe) than to be concerned with what these knowledgeable people know (the content within the pipe) since this content can be directed as needed to anyone with appropriate connections within the pipe.
  • Communities and networks help us to aggregate, filter, and assimilate this information into some kind of knowledge structure and then disseminate it throughout the community or network.
  • distributed learning networks (DLN’s), or personal or professional learning networks (PLNs), or personal learning environments (PLE’s)–all provide direct (and indirect) contact with many people in one’s network, each possessing a reservoir of knowledge which contributes to the entire pool of knowledge residing in the network. This can be accessed through listservs or sometimes almost instantaneously through Twitter or RSS feeds, or Skype, or instant messaging. Therefore the knowledge possessed by any individual, or node in the network, is the sum total of all aggregated knowledge within that network. It is to this that we ascribe the incredible power inherent in distributed learning networks which often comprise to some extent communities of practice.
  • Wenger, McDermott, and Snyder (2002, p. 6) promote the CoP model as an anecdote to the fact, as he puts it, that “increasing complexity of knowledge requires greater … collaboration; whereas … the half life of knowledge is getting shorter.”
  • the skill of leveraging networks is increasingly important in the 21st century in plumbing and aggregating knowledge when that knowledge base is forever changing at an increasingly accelerated pace.
  • or appropriate use of online social networks to be taught in schools, teachers themselves must be familiar with their impact on learning. One problem is that teacher-trainers without sufficient experience with technology and who are rooted in old-school methodologies are simply not modeling new age learning behaviors for their trainees by showing them how to reach out to networks.
  • research indicates that teachers don’t necessarily activate the knowledge they are exposed to in training curricula. The example he gave was on reverting to traditional methods rather than utilizing knowledge about communicative language teaching (Richards, 2009: 4), but the same applies to knowledge of technology.
  • In order for training in pedagogical affordances of networking to take hold it is crucial that teachers be trained not only in social media, but through its use. Those who use social media in their professional networking find this self-evident, but there is at least annecdotal evidence for the need for modeling by mentors.
  • teachers need to be shown the connections between their use of social media in their personal and professional lives. Glogowski and Sessums pointed out in their presentation at the WiAOC 2007 conference their surprise that student teachers who were already using technology with online acquaintances in their after-hours social networking were not carrying this over into their professional teaching practices.

      The same holds true for our students.

Web 2.0: A New Wave of Innovation for Teaching and Learning? (EDUCAUSE Review) | EDUCAU... - 0 views

  • Web 2.0. It is about no single new development. Moreover, the term is often applied to a heterogeneous mix of relatively familiar and also very emergent technologies
  • Ultimately, the label “Web 2.0” is far less important than the concepts, projects, and practices included in its scope.
  • Social software has emerged as a major component of the Web 2.0 movement. The idea dates as far back as the 1960s and JCR Licklider’s thoughts on using networked computing to connect people in order to boost their knowledge and their ability to learn. The Internet technologies of the subsequent generation have been profoundly social, as listservs, Usenet groups, discussion software, groupware, and Web-based communities have linked people around the world.

  • It is true that blogs are Web pages, but their reverse-chronological structure implies a different rhetorical purpose than a Web page, which has no inherent timeliness. That altered rhetoric helped shape a different audience, the blogging public, with its emergent social practices of blogrolling, extensive hyperlinking, and discussion threads attached not to pages but to content chunks within them. Reading and searching this world is significantly different from searching the entire Web world. Still, social software does not indicate a sharp break with the old but, rather, the gradual emergence of a new type of practice.
  • Rather than following the notion of the Web as book, they are predicated on microcontent. Blogs are about posts, not pages. Wikis are streams of conversation, revision, amendment, and truncation. Podcasts are shuttled between Web sites, RSS feeds, and diverse players. These content blocks can be saved, summarized, addressed, copied, quoted, and built into new projects. Browsers respond to this boom in microcontent with bookmarklets in toolbars, letting users fling something from one page into a Web service that yields up another page. AJAX-style pages feed content bits into pages without reloading them, like the frames of old but without such blatant seams. They combine the widely used, open XML standard with Java functions.3 Google Maps is a popular example of this, smoothly drawing directional information and satellite imagery down into a browser.
  • Web 2.0 builds on this original microcontent drive, with users developing Web content, often collaboratively and often open to the world.
  • openness remains a hallmark of this emergent movement, both ideologically and technologically.
  • Drawing on the “wisdom of crowds” argument, Web 2.0 services respond more deeply to users than Web 1.0 services. A leading form of this is a controversial new form of metadata, the folksonomy.
  • Third, people tend to tag socially. That is, they learn from other taggers and respond to other, published groups of tags, or “tagsets.”
  • First, users actually use tags.
  • Social bookmarking is one of the signature Web 2.0 categories, one that did not exist a few years ago and that is now represented by dozens of projects.
  • This is classic social software—and a rare case of people connecting through shared metadata.
  • RawSugar (http://www.rawsugar.com/) and several others expand user personalization. They can present a user’s picture, some background about the person, a feed of their interests, and so on, creating a broader base for bookmark publishing and sharing. This may extend the appeal of the practice to those who find the focus of del.icio.us too narrow. In this way too, a Web 2.0 project learns from others—here, blogs and social networking tools.
  • How can social bookmarking play a role in higher education? Pedagogical applications stem from their affordance of collaborative information discovery.
  • First, they act as an “outboard memory,” a location to store links that might be lost to time, scattered across different browser bookmark settings, or distributed in e-mails, printouts, and Web links. Second, finding people with related interests can magnify one’s work by learning from others or by leading to new collaborations. Third, the practice of user-created tagging can offer new perspectives on one’s research, as clusters of tags reveal patterns (or absences) not immediately visible by examining one of several URLs. Fourth, the ability to create multi-authored bookmark pages can be useful for team projects, as each member can upload resources discovered, no matter their location or timing. Tagging can then surface individual perspectives within the collective. Fifth, following a bookmark site gives insights into the owner’s (or owners’) research, which could play well in a classroom setting as an instructor tracks students’ progress. Students, in turn, can learn from their professor’s discoveries.
  • After e-mail lists, discussion forums, groupware, documents edited and exchanged between individuals, and blogs, perhaps the writing application most thoroughly grounded in social interaction is the wiki. Wiki pages allow users to quickly edit their content from within the browser window.11 They originally hit the Web in the late 1990s (another sign that Web 2.0 is emergent and historical, not a brand-new thing)
  • How do social writing platforms intersect with the world of higher education? They appear to be logistically useful tools for a variety of campus needs, from student group learning to faculty department work to staff collaborations. Pedagogically, one can imagine writing exercises based on these tools, building on the established body of collaborative composition practice. These services offer an alternative platform for peer editing, supporting the now-traditional elements of computer-mediated writing—asynchronous writing, groupwork for distributed members
  • Blogging has become, in many ways, the signature item of social software, being a form of digital writing that has grown rapidly into an influential force in many venues, both on- and off-line. One reason for the popularity of blogs is the way they embody the read/write Web notion. Readers can push back on a blog post by commenting on it. These comments are then addressable, forming new microcontent. Web services have grown up around blog comments, most recently in the form of aggregation tools, such as coComment (http://www.cocomment.com/). CoComment lets users keep track of their comments across myriad sites, via a tiny bookmarklet and a single Web page.
  • Technorati (http://technorati.com/) and IceRocket (http://icerocket.com/) head in the opposite direction of these sites, searching for who (usually a blogger) has recently linked to a specific item or site. Technorati is perhaps the most famous blog-search tool. Among other functions, it has emphasized tagging as part of search and discovery, recommending (and rewarding) users who add tags to their blog posts. Bloggers can register their site for free with Technorati; their posts will then be searchable by content and supplemental tags.
  • Many of these services allow users to save their searches as RSS feeds to be returned to and examined in an RSS reader, such as Bloglines (http://www.bloglines.com/) or NetNewsWire (http://ranchero.com/netnewswire/). This subtle ability is neatly recursive in Web 2.0 terms, since it lets users create microcontent (RSS search terms) about microcontent (blog posts). Being merely text strings, such search feeds are shareable in all sorts of ways, so one can imagine collaborative research projects based on growing swarms of these feeds—social bookmarking plus social search.
  • Students can search the blogosphere for political commentary, current cultural items, public developments in science, business news, and so on.
  • The ability to save and share a search, and in the case of PubSub, to literally search the future, lets students and faculty follow a search over time, perhaps across a span of weeks in a semester. As the live content changes, tools like Waypath’s topic stream, BlogPulse’s trend visualizations, or DayPop’s word generator let a student analyze how a story, topic, idea, or discussion changes over time. Furthermore, the social nature of these tools means that collaboration between classes, departments, campuses, or regions is easily supported. One could imagine faculty and students across the United States following, for example, the career of an Islamic feminist or the outcome of a genomic patent and discussing the issue through these and other Web 2.0 tools. Such a collaboration could, in turn, be discovered, followed, and perhaps joined by students and faculty around the world. Extending the image, one can imagine such a social research object becoming a learning object or an alternative to courseware.
  • A glance at Blogdex offers a rough snapshot of what the blogosphere is tending to pay attention to.
  • A closer look at an individual Blogdex result reveals the blogs that link to a story. As we saw with del.icio.us, this publication of interest allows the user to follow up on commentary, to see why those links are there, and to learn about those doing the linking. Once again, this is a service that connects people through shared interest in information.
  • The rich search possibilities opened up by these tools can further enhance the pedagogy of current events. A political science class could explore different views of a news story through traditional media using Google News, then from the world of blogs via Memeorandum. A history class could use Blogdex in an exercise in thinking about worldviews. There are also possibilities for a campus information environment. What would a student newspaper look like, for example, with a section based on the Digg approach or the OhmyNews structure? Thematizing these tools as objects for academic scrutiny, the operation and success of such projects is worthy of study in numerous disciplines, from communication to media studies, sociology to computer science.
  • At the same time, many services are hosted externally to academia. They are the creations of enthusiasts or business enterprises and do not necessarily embrace the culture of higher education.
  • Lawrence Lessig, J. D. Lasica, and others remind us that as tools get easier to use and practices become more widespread, it also becomes easier for average citizens to commit copyright violations.19

      Which is why he led the Creative Commons Movement and why he exhorts us to re-imagine copyright.
  • Web 2.0’s lowered barrier to entry may influence a variety of cultural forms with powerful implications for education, from storytelling to classroom teaching to individual learning. It is much simpler to set up a del.icio.us tag for a topic one wants to pursue or to spin off a blog or blog departmental topic than it is to physically meet co-learners and experts in a classroom or even to track down a professor. Starting a wiki-level text entry is far easier than beginning an article or book.
  • How can higher education respond, when it offers a complex, contradictory mix of openness and restriction, public engagement and cloistering?

  • The rapid increase in the availability of high-bandwidth Internet service, coupled with a wide array of interactive software, has touched off a new wave of experimentation in education.
  • Dr. Widom said she had recorded her video lectures during the summer and would use classroom sessions to work with smaller groups of students on projects that might be competitive and to bring in people from the industry to give special lectures. Unlike the A.I. course, this one will compare online students with one another and not with the Stanford students.
