    • technology is finally at a point that if we don’t use it now, then we are holding back the progress of science
    • The dominant mode of communicating research results is through peer-reviewed literature. This dates back to more than 300 years ago when scholarly societies formed and needed a way to present their findings
    • Publishers are already experimenting with the models, but they are waiting for something before going full force. They are waiting for us, the researchers
    • We could choose to publish in only Open Access. We could choose to reward tenure for Open Data. We could choose to only reward publications or data that are proven to be reused and make either a marked economic or research impact. Instead, we choose to follow a model that promotes prestige as the primary objective
    • Each time we hold back data or publish research that isn’t immediately open to all, we have chosen to be on the wrong side of history.
    • We could wait for policy changes from the top, but that is neither a timely, nor guaranteed solution
    • It is not uncommon to see research that is already two years old before it sees the light of day. This cannot be good for the progress of science.
    • “Article-level metrics” (ALM) is one step toward weaning the addiction that we have with journal impact factors. Here, we disassociate the significance of the article from the prestige of the journal that it is packaged in
    • One way to promote the sharing of knowledge, and thus be on the right side of history, is through reputation metrics. Unlike previous measurements for impact though, this would be designed to reward researchers who contribute to Open Data and science online
    • Platforms such as Mendeley can have a hand in meeting both the first and second conditions. Mendeley is more than just a reference manager, it is also a system that aggregates the metadata of millions of documents and provides authors the opportunity to promote their works
    • Those researchers who openly and quickly publish research or data for download will be rewarded.* Those who do not will adapt or risk falling into obscurity. As we wait for policy changes to be enacted by the top, we must act at the bottom to encourage a behavioral change in how we share our knowledge
    • All of our attention is focused on real and virtual classrooms and we often neglect the space between the lecture theater and the LMS. Attention, I think, needs to be given to unacknowledged learning and teaching places. Around the water cooler, between computer terminals, seated in the cafetaria, texting on mobile phones, waiting on strategically placed benches, posted on signboards, relaxing in a residence hall etc.
    • Learning designers need to think between the corridors and computers, and ask how can these spaces be used to support learning.
    • Where discussions and clarification took place either in the lecture / tutorial / virtual room, teachers and students that use networked digital devices can conduct their teaching and learning seamlessly across both physical and virtual spaces, synchronously and asynchronously
    • learning designers also need to find a way to support the creation of informal learning space between the virtual world and the classroom place.
    • If our attention is focused only between the real and virtual classrooms then it’s likely that we’ll fail in our attempt to use these new spaces constructively
    • don’t forget about the inbetween spaces and ask how you can support students freedom to engage in self-directed and independent learning outside the formally planned and tutor-directed activities

    • Gregory A. Moses, a professor of engineering physics at the University of Wisconsin at Madison, has tried to reverse the “lecture-homework paradigm” in a computational science course. Instead of watching a lecture and doing homework later, outside the classroom, students study the lectures on their own time online. Class is a lab, with students solving problems under the supervision of faculty. Mr. Moses went from “not knowing the names of the students in his huge lectures to knowing which ones smoked and which ones didn’t”
    • In scholarship and research, having a ‘problem’ is at the heart of the investigative process; it is the compound of the generative questions around which all creative and productive activity revolves
    • But in one’s teaching, a ‘problem’ is something you don’t want to have, and if you have one, you probably want to fix it
    • Changing the status of the problem in teaching from terminal remediation to ongoing investigation is precisely what the movement for a scholarship of teaching is all about
    • many of us struggle to find the objectivity necessary to reflect and analyze the problem
    • Teaching problems are best solved intellectually, not emotionally
    • You can solve the problem on your own in the privacy of your classroom and be proud of the solution. But your colleague across the hall may have a better solution or may have figured out how that solution can be applied to other problems

  • Simply labelling a group as a community neither ensures that it functions as one, nor that it is a beneficial, cohesive unit in which learning will take place readily
  • Riel and Polin  propose a typology of three ‘distinct but overlapping forms of learning within communities’
      1. Task-based: groups of people working together intently over a limited period of time on a particular product
      2. Practice-based: usually based around a profession or discipline, these groups focus on sharing and developing good practice
      3. Knowledge-based: here the focus is on the use and reuse of knowledge in a never ending cycle
  • These typologies to be useful in identifying perhaps extreme examples of communities, however in the majority of cases examples of working communities for learning are a hybrid of all three types
  • Effectively collaborating in joint activities, producing useful outputs related to practice and helping to advance the state-of-the art in domain knowledge

    xWeb « Connectivism Annotated

    • Naming things is important. It’s easier to say “web 2.0″ than “participative, fragmented content, conversation-driven web”. Unfortunately, names give shape to concepts that are often imprecise. Sometimes words hurt more than they help.
    • xWeb is the utilization of smart, structured data drawn from our physical and virtual interactions and identities to extend our capacity to be known by others and by systems. This is an imprecise definition, but it’s a start
    • It involves a negotiation of two key questions that I continue to grapple with:

      1. What does technology do better than people?

      2. What do people do better than technology?

    With xWeb, we are rethinking what we have to do as people and starting to rely on what technology does better than we possibly could. Over the last few years, I’ve been trying to capture the nature of the change around technology. Some of the recurring themes:

  • augmentation
  • aggregation
  • semantic web
  • location-based services (geoweb)
  • data overlaya
  • smart information
  • visualization
  • social media
  • open data and data in general
  • Internet of things
  • cloud computing
  • mobile technologies
  • analytics and monitoring
  • And, to that list, we could add filtering, recommender systems, distributed “like this” tools, annotation tools (diigo), wearable computing, and so on
      • Web 1.0 mainly seemed to consist of semantics, Web 2.0 of connections, communications, multi-media, virtual worlds and the introduction of mobile devices through the emergence of wireless and higher Internet connection speeds; while Web 3.0 connects data streams in a supposedly intelligent way. The combination of all four would lead to Web X.0 (Steve) or Web X (Stephen)
      • Why would anybody need some researchers and developers to work on a PLE for them?
      • 1. Intelligent data connections are one exciting option for PLE development and networked learning. Recommender systems of information, resources, critical friends and experts could form part of the access options for learners in a PLE that they would not likely be finding in a self-directed fashion
      • 2. That brings me to the challenges of an open online networked environment for learning. Not all adult learners are able to critically assess what they find online and might prefer to receive guidance from knowledgeable others
      • educators have highlighted that there is a real need for critical literacies while learning informally on networks
      • people might not necessarily have the critical literacies required to learn and search independently
      • Learning in my view is not synonymous with accessing information, and requires a level of reflection, analysis, perhaps also of problem solving, creativity and interaction with people to be able to get the best out of the structures and sub-structures of the Internet
      • the majority of people in the northern hemisphere should now have access to technology (so happy to see Rita qualify the statement with “…in the northern hemisphere…”)

      • The people least likely to use the Internet are also the least likely to participate in adult education
      • And I haven’t even spoken about the people on the southern half of the globe, where the access and participation rate to technology and learning is even lower and the group of vulnerable people greater. Should we just leave these people behind?
      • The components that were formulated in Stephen Downes’ vision for a PLE at the start of the PLE project of the National Research Council of Canada are the following: 1. A personal profiler that would collect and store personal information. 2. An information and resource aggregator to collect information and resources. 3. Editors and publishers enabling people to produce and publish artifacts to aid the learning and interest of others. 4. Helper applications that would provide the pedagogical backbone of the PLE and make connections with other internet services to help the learner make sense of information, applications and resources. 5. Services of the learners choice. 6. Recommenders of information and resources.
      • Having been born into a world where personal computers were not a revolution, but merely existed alongside air conditioning, microwaves and other appliances, there has been (a perhaps misguided) perception that the young are more digitally in-tune with the ways of the Web than others
      • Apparently, the students favor search engine rankings above all other factors. The only thing that matters is that something is the top search result, not that it’s legit.
      • many students trusted in rankings above all else
      • researchers found that even in this supposedly savvy minority, none actually followed through to verify the identification or qualifications of the site’s authors
      • students are not always turning to the most relevant clues to determine the credibility of online content
      • Several strands of research demonstrate that displaying a personal interest in students is not only effective as a way to encourage participation and engagement, but necessary for real learning negative emotions such as fear and shame, all too common in the college classroom, retard learning, due to “choking,” the shutting down of higher-order thinking, and the activation of more primitive areas of the brain associated with the fight-or-flight syndrome

        undergraduate students repeatedly mention the importance of one-to-one interaction with instructors. Displaying a personal interest in students is the first step toward demonstrating that community exists within the classroom and across the campus

      • Be available to students in ways that you judge are not too invasive of your personal boundaries

        Encourage and respond to email

        Solicit and respond to student feedback

      • Mid-semester evaluations that you create and use to fine-tune instruction midstream also convey to students that you care what they think and about their learning

        During discussions and other interactions with students, really listen to them, striving to hear what students are really saying; not what we want to hear and/or assume students are saying

      • making connections between academic material and students’ personal experience also conveys an interest in students and their learning.

      • Faculty members with strong research records and below-average teaching routinely get to be full professors, while outstanding teachers with below-average (and sometimes average) research productivity don’t get tenure
      • Depressingly many research papers are published that have little or no impact on technology or society and are never cited by anyone other than their authors
      • If university administrators were being honest, they would state that they need massive amounts of external research funding to function, the chancellor of a university that proclaimed teaching to be of secondary importance would have to face some hard and unwelcome questions, so what happens instead is rationalization
      • There is no logical reason to expect productivity in research and effectiveness in teaching to be closely related, since research and teaching have different goals and require different skills and personal attributes
      • The goal of research is to advance knowledge, while that of teaching is to develop and enhance abilities
      • Excellent researchers must be observant, objective, skilled at drawing inferences, and tolerant of ambiguity; excellent teachers must be skilled at communication, familiar with the conditions that promote learning and expert at establishing them, approachable, and empathetic
      • Having both sets of traits is clearly desirable but not at all necessary to succeed in one domain or the other
      • Moreover, first-class teaching and first-class research can each consume well over 40 hours a week, so that time spent on one activity is inevitably time taken from the other
      • It should therefore come as no surprise if studies reveal no significant correlations between research productivity and teaching effectiveness
      • Argument: Research productivity correlates positively with teaching effectiveness. Fact: Wrong. Correlations between numbers of papers and grants and measures of teaching quality such as student evaluations, peer evaluations, and learning outcomes are mostly negligible and sometimes negative

      • Argument: Research-intensive universities provide the best undergraduate education. Fact: Wrong. In reality, significant negative correlations have been found between a university’s research orientation and numerous student learning and satisfaction outcomes

      • Argument: Only active researchers are sufficiently current in science and engineering to be viable teachers. Fact: Never demonstrated, and almost certainly wrong

      • Argument: Faculty with active research programs bring their research into the classroom and use it to inform and enliven their teaching. Fact: Usually wrong, especially in undergraduate classes, and when research is integrated into teaching it’s not always a good thing. Most current research is well beyond the scope of all but advanced graduate courses, and rigid curricula make it challenging to bring in new material

      • Argument: Research experiences enhance undergraduate education. Fact: True for some students. No supporting evidence exists for this presumption; in fact, much undergraduate research directed by research faculty has students functioning more as unpaid lab technicians than as true researchers

      • In short, the unwritten rule that all university faculty should be active researchers places unreasonable and unhealthy demands on faculty members; weakens departmental teaching programs; keeps potentially outstanding teachers from devoting enough time and energy to teaching to realize their potential; deprives students of some inspirational and possibly life-changing instructors, mentors, and role models; and is unsupportable by either logic or research
      • Flexible Thinking: In a world in which future workers are likely to have as many as eight careers or more in their lifetimes, lifelong learning will be essential but flexibility of thought will be equally critical, enabling individuals to move seamlessly from one transition to another
      • Multiple Interpretations: The New Civic Discourse driver from the 2020 Forecast depicts a world in which continuous, bottom-up communication will be the norm, bringing an ever-widening circle of individuals with divergent views into contact with one another. If this dialogue is to be fruitful, not fractious, we will need to develop a new capacity for dialogue which includes the capacity to see multiple perspectives
      • Willingness to Experiment and Learning from Mistakes: Dynamism and acceleration are hallmarks of our current age. To innovate in this world, rapid beta-building and the habits of mind such as a willingness to experiment and reframing of “mistakes” as failures, to “mistake” as learning opportunities will be required
      • Visual and Spatial Abilities: If we are to make sense of the vast amounts of knowledge we are creating, the knowledge era must become the visual era. We need to develop the capacity to bring multiple streams of information together in new ways to provide sophisticated and elegant pictures of complex situations

      • in 20 years, I want to be reading that story about my kids, about their passions being fulfilled in ways that can earn them a living solving problems and helping to make the world a better place
      • And I want my kids’ schools to help them do that
        the focus points he provides for assessment:
        • Learn (What did you know? What are you able to do?)
        • Understand (What is the evidence that you can apply learning in one domain to another?)
        • Share (How did you use what you have learned to help a person, the class, the community or the planet?)
        • Explore (What did you learn beyond the limits of the lesson? What mistakes did you make, and how did you learn from them?)
        • Create (What new ideas, knowledge, or understanding can you offer?)
    • moves the conversation not only away from the standardized framework to a more fluid one, but advocates doing all of it transparently, and, importantly, focuses on group assessments not just individual ones
    • It gives a whole different picture of learning as an ongoing process, not an event, not something that can be summed up in the reporting back of a few facts and figures on a short answer test
    • Students are not merely consumers of education laboring for their next reward. Their success is measured not just in terms of tests passed, but by the ways in which they apply their earning to help others. They measure their significance not by how they have distinguished themselves, but by the impact that they had on their communities and the world.
    • Two depressing facts about assessment keep weighing me down in all of this. First we teach what we assess, and second, we get the assessments we can afford (both in time and in money.)
    • a third depressing fact is that this will require us to be able to step out of our own school experience, to be willing to define success in ways that are unfamiliar and more nuanced
      • A loose-knit online learning community can scale to many participants and remain effective.
      • Only a small percentage ~10% of members will be active.
      • Wikis need to be extremely focused on real tasks/projects in order to be adopted.
      • If facilitators can seed good questions and provide feedback, then conversations can flourish.
      • Use a very gentle hand in controlling the learners and some will become highly participative.
      • Design for after the course, using tools like social bookmarks, so that artifacts can be used for reference or performance support.
      • Create the role of “synthesizer”. I found it quite helpful when Tony and Michele summarized the previous week’s activities.
      • Keep the structure loose enough so that it can grow or change according to the needs of the community.

      • The foundations of any discipline are its definition, knowledge base, terminology, structure, methodology, and epistemology
      • While traditional teaching methods, especially lecture and readings, are quite efficient at “delivering” this kind of information, the question is whether “delivery” is enough
      • there are two essential tasks to foster student achievement: help students see the relevance and importance of the information, and make it understandable
      • the dimensions of teaching that are the strongest correlates of student achievement are: 1) preparation and organization; 2) clarity of communication; 3) perceived outcome of the instruction; and 4) stimulating student interest in the course content
      • Teachers must possess a great deal of different kinds of knowledge:
      • The first is “content knowledge,”
      • The second is “pedagogical content knowledge,” or understanding of pedagogy, teaching and learning, and its application to the discipline
      • Finally is “curricular knowledge,” an enhanced version of the latter where the teacher has a repertoire of strategies, materials, approaches, and alternatives that are called on to help students learn
      • the teacher provides both the organizational structure and the appropriate level of complexity for the students
      • However, structuring and organizing information and activities does not mean exercising complete control over all aspects of the course
      • Incorporate motivational strategies into your teaching, using activities that allow students to find information, to organize it in meaningful ways, or to use it, all have the potential to provide opportunities for success and intrinsic motivation
      • When students passively sit and listen to 50 minutes or more of a lecture, they have little investment in learning except to do it in order to pass a test and get a grade
      • You can exhibit skills that help students to see structure, to relate topics, and to organize information
      • A teacher who says, “This is how we approach a problem in our discipline” or “This is how I would go about answering this question,” is showing students a process that is transferable
      • Even when dealing with knowledge level objectives, a teacher can show students how topics relate to and build on each other
      • Content-heavy courses may not seem to be the right places for instructional methods that have been shown to enhance conceptual learning, but conceptual understanding can often help students make sense of the facts, terms, and organization of the subject
      • When you ask students to organize information or place it in context (and that, in itself, can be a team assignment) you help them to construct more complete knowledge
      • Concept maps (14) are useful at this level because they provide a structural picture of the relationships of information and concepts
      • When the objective is for students to learn basic facts, the assessments you choose should provide direct evidence of knowledge
      • they should also link that knowledge to deeper understanding of the material
      • Courses that most often require students to learn basic information are frequently offered in the first year and in large-enrollment settings
      • Your students probably have little experience with the content and they may not have sophisticated learning skills
      • You cannot wait until mid-semester or later to assess learning
      • When you and your students know what needs attention, both teaching and learning become more efficient
      • assessment with feedback is most beneficial for student learning
      • the objective is not simply to determine right or wrong, but rather to focus on why a given answer is correct and on the process used to arrive at that answer

      • So little of what we read or see in the field of online learning is concerned with providing people with the tools they need to create their own freedom. “The master’s tools will never dismantle the master’s house.”
      • In these tools there is, and will always be, embedded a dependence back to the originator of the tool, back to the system of mass that makes it both possible and necessary
      • I work with and for what I believe the internet truly is – an explosion of capacity thrust into the hands of people worldwide, the instrument not only for the greatest outburst of creativity and self-expression ever seen, but also of the greatest autonomy and self-determination, and as well on top of that an unparalleled mechanism for cooperation and cohesion
      • The freedom of each of us to form and to have and to share our own thoughts, created by us, contributed freely to the world, and a society built, not on the basis of a propagation of ideas, but rather, on the basis of a gathering of them

    Posted to Diigo 06/18/2010

      • Salmon’s model moves away from the increasingly dated notion that the effective eLearning can be achieved through static learning objects (Downes 2005), and takes a social learning perspective with particular emphasis on communities of practice, providing a framework to support Wenger’s assertion that “learning cannot be designed: it can only be designed for – that is, facilitated or frustrated” (1998, p. 228).
      • Salmon’s model is also reliant upon scaffolding, extending Vygotsky’s Zone of Proximal Development (in Attwell 2006) proposition with the model’s structure implying that the moderator acts as an initial scaffold who gradually shifts responsibility for development to the learning community under their guidance, with learners developing their own scaffolding based on relationships with many within the community, and eventually, beyond the community.
      • Lead by Example
      • It is an essential part of our jobs to model what we would like to see
      • Get Personal
      • Be willing to share of yourself. Share your stories and your life
      • be willing to be open
      • Be Honest
      • you need to be willing to share your thoughts and opinions about things
      • Accept that You’re Human
      • Learn for mistakes and move on
      • Be Knowledgeable and Share
      • Share of yourself and of your passions. Make your presence in a space one that has personality and share what you have
      • Share the things you find online
      • Maintain Consistency
      • Maintaining consistency will allow your students to be comfortable in your space, understanding what happens there and able to concentrate on what they are being asked to do
      • Let it Go
      • Be prepared to see cycles between students and even within the contributions of single students
      • Don’t Give Up
      • How can we change what we are asking them to do in order for them to grow into their roles
      • “My job is to present the material in an interesting and meaningful way,” he would say. “It is the student’s job to learn that material.”

        Implicit in his statement was the idea that it was the student’s role to adjust to the various styles employed by different teachers. Whether the teacher featured a lecture format or a hands-on approach was immaterial – the assumption was that students were the ones who needed to be flexible

      • any failure on the student’s part to master the material was not the responsibility of the teacher
      • students moved along as a group, each doing the same set of assignments, each expected to master the exact same set of learning objectives by a date set forth in the syllabus
      • differentiating for a specific learner was perceived as showing favoritism
      • today’s teacher is expected to adjust to the varied preferences of students so as to maximize the learning potential of each individual in the classroom
      • Personalizing learning involves differentiating the curricula, including expectations and timelines, and utilizing various instructional approaches so as to best meet the needs of each individual
      • The challenge is not so much what those elements consist of but how to piece the elements together to form a cohesive strategy
      • But technology also plays a more important role in the personalization process. Ultimately it is the conduit for teachers to move to a learning approach that features materials developed for each individual student
      • One of the critical elements to a cohesive strategy involves the concept of a learning platform
      • First teachers must have a clear understanding of the learning needs of each student
      • teachers must monitor and assess student progress intently
      • Learning paths must then be created that match the aptitude and learning styles of every individual
      • One of the first elements is increased communication among educators themselves as well as with their individual students
      • That means increased use of email
      • Better yet, it means posting that assignment online for students and parents to access directly
      • No one educator could possibly create unique learning materials for every single student
      • An expectation that all teachers are ready for such steps is destined for failure
      • Whereas in Africa limited infrastructure is producing an information bottleneck, access in the UK is restricted by ‘denial of service’ restrictions placed upon a competent and fast modern system
      • how do we go about managing the risks more effectively to allow NHS staff to access online learning resources and tools which many of us take for granted
      • what processes people perceived as important for knowledge maturing within their organisation and how ell they though these processes were important. The two processes perceived as most important were ‘reflection’ and ‘building relationships’ between people. These were also the two processes seen as amongst the least supported
      • The issue of ‘reflection’ is more complex. e-Portfolio researchers have always emphasised the centrality of reflection to learning, yet it is hard to see concrete examples of how this can be supported
      • the amount of redundant, inconsequential, and outright poor research has swelled in recent decades
      • 40.6 percent of the articles published in the top science and social-science journals (the figures do not include the humanities) were cited in the period 2002 to 2006
      • As a result, instead of contributing to knowledge in various disciplines, the increasing number of low-cited publications only adds to the bulk of words and numbers to be reviewed
      • The avalanche of ignored research has a profoundly damaging effect on the enterprise as a whole. Not only does the uncited work itself require years of field and library or laboratory research. It also requires colleagues to read it and provide feedback, as well as reviewers to evaluate it formally for publication. Then, once it is published, it joins the multitudes of other, related publications that researchers must read and evaluate for relevance to their own work. Reviewer time and energy requirements multiply by the year
      • The pace of publication accelerates, encouraging projects that don’t require extensive, time-consuming inquiry and evidence gathering
      • Questionable work finds its way more easily through the review process and enters into the domain of knowledge
      • Aspiring researchers are turned into publish-or-perish entrepreneurs, often becoming more or less cynical about the higher ideals of the pursuit of knowledge
      • The surest guarantee of integrity, peer review, falls under a debilitating crush of findings, for peer review can handle only so much material without breaking down. More isn’t better. At some point, quality gives way to quantity
      • Several fixes come to mind:
      • First, limit the number of papers to the best three, four, or five that a job or promotion candidate can submit. That would encourage more comprehensive and focused publishing
      • Second, make more use of citation and journal “impact factors
      • Third, change the length of papers published in print: Limit manuscripts to five to six journal-length pages
      • and put a longer version up on a journal’s Web site
      • what we surely need is a change in the academic culture that has given rise to the oversupply of journals
      • Finally, researchers themselves would devote more attention to fewer and better papers actually published, and more journals might be more discriminating
      • the present ‘industrial’ schooling system is fast becoming dysfunctional, neither providing the skills and competences required in our economies nor corresponding to the ways in which we are using the procedural and social aspects of technology for learning and developing and sharing knowledge
      • Personal Learning Environments can support and mediate individual and group based learning in multiple contexts and promote learner autonomy and control
      • The role of teachers in such an environment would be to support, model and scaffold learning
      • Such approaches to learning recognise the role of informal learning and the role of context
      • Schools can only form one part of such collaborative and networked knowledge constellation
      • institutions must rethink and recast their role as part of community and distributed networks supporting learning and collaborative knowledge development
      • the major impact of the uses of new technologies and social networking for learning is to move learning out of the institutions and into wider society
      • This is a two way process, not only schools reaching outwards, but also opening up to the community, distributed or otherwise, to join in collaborative learning processes
      • At the same time new interfaces to computers and networks are likely to render the keyboard obsolescent, allowing the integration of computers and learning in everyday life and activity

      • the push to use technology in the classroom has diminished the roles of teaching and education
      • Easily the best-named session of the conference was “We Can’t Give Enemas Online — Strategies for Moving Nursing Faculty to Online Programming
      • If technology is helping us teach better, why are we seeing so much evidence that students aren’t learning as well as we would like?
      • Current college students have had more exposure to technology in high school and college than previous generations did, but are they better off for it?
      • “There is a science and an art to teaching,” he said. And if technology is part of the science, it’s time to focus anew on the art
      • there were repeated calls to take back the classroom
      • “when you are lecturing, you are unfolding ideas, and on the screen you have an immediate snapshot.”
