    1. Enhanced learning experience Graduate students now receive upgraded iPads, and all students access course materials with Canvas, a new learning management software. The School of Aeronautics is now the College of Aeronautics; and the College of Business and Management is hosting a business symposium Nov. 15.

      This from a university which had dropped Blackboard for iTunes U.

    1. And, in general, to observe with intelligence & faithfulness all the social relations under which he shall be placed.

      I think this passage highlights everything we still learn today as students not just in the classroom, but outside of it. As students we not only learn from our professors, but from each other, and we do that through our social interactions and relations. In collaborating with other students wether it be in the lab, working on a group project, or just engaging in conversation with a group of friends, we are learning new ideas and skills, which is an important skill we must take with us into the real world that we'll enter after college. -Emily McClung

    1. Download Dr. Brad Wheeler leads university-wide IT services for IU's eight campuses. He has co-founded and led many multi-institutional collaborations with his current work focused on the Unizin Consortium, Kuali, and IU’s mass Media Digitization and Preservation Initiative.
    1. Information from this will be used to develop learning analytics software features, which will have these functions: Description of learning engagement and progress, Diagnosis of learning engagement and progress, Prediction of learning progress, and Prescription (recommendations) for improvement of learning progress.

      As good a summary of Learning Analytics as any.

    1. Better yet, tangerines and oranges.

      Is that about the colours favoured by both platforms? Does sound like it weakens the point (going from comparing fruits to comparing one citrus with another). The point, eventually, is that Canvas and Moodle occupy a similar space: course-based “learning” management systems.

    1. LRSs will typically only have minor data analysis built in as it's specific to the type of information you are trying to track.
    1. UML automatically finds these hidden patterns to link seemingly unrelated accounts and customers. These links can be one of thousands of data fields that the UML model ingests.

      Why does this have to be done in a different system?

    1. but the occupation reported as having the largest number of former master’s students was kindergarten–Grade 12 (K–12) teacher. These results demonstrate that master’s degree graduates in learning sciences have the potential to influence practice in a diverse range of applied settings.

      Considering that 31% of master graduates are in the K-12 teachers or educational leaders and administrators, it would be interesting to see what would happen if they implement the learning theories into their classrooms and schools.

    1. COMPETENCY-BASED LEARNING

      Close reading is basically standardized in Common Core--it's referenced in the first ELA anchor standard for reading. Hypothesis is a means to assess competency in that standard by recording, measuring, and allowing feedback on

    2. Students working in waysthat best leverage their individual learning styles

      In annotation, each student bringing their style, expertise, experience to the text with the class as a group sharing a more wholistic view of the related issues.

    3. “What did you do? What did you observe? What did you revise as a result? How did you test your revision? What did you learn?”

      Students annotating their own revisions as self-review.

    4. electronic journals as a way to reflect on their learning and “make their thinking visible.”

      This could be accomplished in annotation if Hypothesis had the concept of a 1:1 note.

    5. Motivation and persistence. Because learning is more relevant and relationship-based, students are motivated to complete tasks and learn

      Collaborative annotation can be used to scaffold self-directed learning, providing a means for a student to explore their own interests and provide evidence of that activity, and enabling teachers to monitor and interact with these knowledge pathways.

    6. students “own” their learning

      Student ownership and agency through annotation as an intellectual practice with a record.

    7. Students encouraging and supporting eachother to work through diicult challenges

      via annotation made explicit in prompt for assignment

    8. Students constructivelycritiquing eachother’s work

      via annotation

    9. Assessment feedback focused on what students can do to improve

      Hypothesis needs a 1:1 channel internal to the client. For now, the LMS app allows for this type of feedback.

    10. no single “right answer”?

      Social reading is discussion not test-driven knowledge production.

    11. Are students required to defend and revise their work, creating multiple drafts?

      The natural thinking processes of a threaded conversation in annotation with comment replies, replies to replies, etc.

    12. Teachers talking less, students talking more

      Social reading is active reading. Texts filled with student voices.

    13. Are students constantly revising and improving their work? How often? How explicit and central is this expectation?

      Annotation as final product but also as pre-writing, harvested for summative assignments.

    14. Are students regularly asked to present, explain, and defend their ideas orally and in writing?

      This is the basic work of a critical annotation.

    15. And outside the classroom, meetings with public oicials, nonprofits, and other community members, where students are given a chance to present their findings and recommendations on an issue they’ve researched

      Public annotation of government documents/websites, newspaper articles, etc.

    16. Communications skills being explicitly taught

      Again, social annotation/reading provide an opportunity for this kind of instruction: teacher has a view into how students are interacting with each other (and text).

    17. Multimedia portfolios of student work

      Profile pages of annotation are a kind of this portfolio or a contribution.

    18. Listening

      A big part of social reading: listening to the text and to other readers.

    19. review and critique each other’s work.

      This is the process of replying to annotations. But annotation can also be leveraged for peer review of student writing.

    20. Public presentations of their work. Students routinely have to describe and defend their thinking with peers, teachers, and the community. Students say that such public presentations reinforce their sense of accountability and make them be more careful with their work.

      Moving annotation from a private practice with little accountability to something shared with the immediate social group of the classroom and finally to the larger public of the annotated web with students making interventions as digital citizens.

    21. learning how to conduct their own research, often on the Internet.

      Collaborative annotation and independent inquiry: students reading what they're interested and annotating; teachers following along in the process through activity pages.

    22. more engaging

      Because social and interactive, collaborative annotation can make reading more engaging.

    23. peer-to-peer conversations about big issues that defy yes/no answers and ask students to think more analytically

      Pretty good definition of social reading in fact!

    24. embedding communications skills into everything they do in all of their courses: speaking, listening, reading, and writing?

      Again, socializing reading (and writing) to an extent, makes those skills more real, necessary, part of a relationship, a community, rather than an individual task.

    25. working with members of the community

      Public annotation.

    26. holding themselves accountable

      Can annotation portfolios/profile be leveraged to this end? Students have an activity page that represents their engagement with reading and with each other. Maybe ask students to reflect on their contributions.

    27. build relationships through mechanisms

      Annotation as one such mechanism: learning, reading in community.

    28. egularly working on teams

      Social reading makes reading a team sport!

    29. constructive feedback

      Via annotation. As a measurable skill.

    30. Lots of talking and listening; a constant exchange of ideas

      Live and asynchronously using collaborative annotation.

    31. Inter- and intra-personal skills. Character and culture are important values that are emphasized as much as academic subjects

      A student's "social reading" profile provides a window not only into how they interact with text (comprehensively, critically?) but also into how they interact with their classmates (respectfully? discursively?).

    32. listen well—to be a good “critical friend.”

      Read classmate's annotations, respond appropriately: respectful, challenging...

    33. learn as much from their peers as from their teachers or a textbook

      Or combing all three in a single conversation...

    34. EVIDENCE OF THINKING, NOT JUST GROUP WORK

      Students working collaboratively through the meaning of a text in annotation, asking questions, answering others, building off each other's comments and knowledge.

    35. key skills they then can apply to other situations beyond this specific course or assessment

      Collaborative annotation as a way to assess skills rather than content mastery. Or in addition to.

    36. Teachers stepping into conversations or stopping work from time to time for “teachable moments” to supplement knowledge

      Via annotation in the case of readings/reading discussion.

    37. reading original sources

      Primary sources, reading of, key.

    1. providing teachers and students with real-time, actionable feedback.

      Via annotation?

    2. go beyond basic math and English skills.

      Not content based, but skills based?

    1. a system of evaluation called the Learning Record (LR). This system asks students to make an argument for their grade (at the mid-term and at the end of the course) that is based upon the evidence they have compiled throughout the semester.

      If I teach again, I'm going to use this.

    1. By giving student data to the students themselves, and encouraging active reflection on the relationship between behavior and outcomes, colleges and universities can encourage students to take active responsibility for their education in a way that not only affects their chances of academic success, but also cultivates the kind of mindset that will increase their chances of success in life and career after graduation.
    2. If students do not complete the courses they need to graduate, they can’t progress.

      The #retention perspective in Learning Analytics: learners succeed by completing courses. Can we think of learning success in other ways? Maybe through other forms of recognition than passing grades?

    1. The flexibility and social nature of how technology infuses other aspects of our lives is not captured by the model of Personalized Instruction, which focuses on the isolated individual’s personal path to a fixed end-point. To truly harness the power of modern technology, we need a new vision for educational technology (Enyedy, 2014: 16).
    1. As an outcome of this Delphi Panel exercise, this study hasrevised Jane Knight’s commonlyaccepted working definition for internationalisation as'theintentionalprocess ofintegrating an international, intercultural or global dimension into the purpose, functionsand delivery of post-secondary education,in order to enhance the quality of educationand research for all students and staff, and to make a meaningful contribution tosociety'.This definition reflects the increased awareness that internationalisation has to becomemore inclusive and less elitistby not focusing predominantly on mobility but more on thecurriculum and learning outcomes. The ‘abroad’ component (mobility) needs to become anintegral part of the internationalised curriculum to ensure internationalisation for all, notonly the mobile minority. It re-emphasises that internationalisation is not a goal in itself,but a means to enhance quality, and that it should not focus solely on economic rationales.Most national strategies, including in Europe, are still predominantly focused on mobility,short-term and/or long-term economic gains, recruitment and/or training of talentedstudents and scholars, and international reputation and visibility. This implies that fargreater efforts are still needed to incorporate these approaches into more comprehensivestrategies, in which internationalisation of the curriculum and learning outcomes, as ameans to enhance the quality of education and research, receive more attention. Theinclusion of ‘internationalisation at home’ as a third pillar in the internationalisation strategyof the European Commission,European Higher Education in the World, as well as in severalnational strategies, is a good starting point, but it will require more concrete actions at theEuropean, national and,in particular, the institutional level for it to becomereality

      Using inclusive approaches to ensure all students have access to quality teaching and learning and why it shouldn't be limited to the mobile few. I find it interesting since a lot of research focuses on the gain for international students only.

    1. Overall, across the ALMAP trials, adding adaptivity to developmental and gateway courses had no effect on course completion rates after controlling for students’ initial achievement levels under any of the three possible use cases.
    1. It’s precisely to meet these demands that Cegid recently launched a Learning Management System (LMS) specifically dedicated to Healthcare, a sector that is converting more and more to cloud-based systems.

      Norman's Law of eLearning Tool Convergence

      Any eLearning tool, no matter how openly designed, will eventually become indistinguishable from a Learning Management System once a threshold of supported use-cases has been reached.

    1. “The notion that adaptive technology is the reason why one school should choose one company’s content over OER (open educational resources) or other options” has become a staple of many publisher’s marketing claims, says Trace Urdan, an education market analyst.

    1. Đầu tiên mình nghĩ bạn cần nắm về machine learning và algorithm, bạn có thể bắt đầu bằng các khóa học trên mạng. Mình recommend khóa học Machine Learning của Andrew Ng, khóa học này được coi là kinh thánh cho data scientist. Sau đó bạn có thể bắt đầu với Python hoặc R và tham gia challenge trên Kaggle. Kaggle là một platform để Data Scientist tham gia, kiếm tiền thưởng và cạnh tranh thứ hạng với nhau. Nhiều người cũng nói với mình Kaggle là con đường tốt nhất và ngắn nhất để đến với Data Science.

    1. Analyze, interpret, and evaluate a variety of texts for the ethical and logical uses of evidence

      This could be a series of tags determined by prof.

    1. Based on this experiment, the evidence suggests adaptive learning did not improve grades or rates of course completion. The tech is still too new to make a definitive judgment.

      Interesting, the evidence for efficacy is still not there (yet).

    2. Textbook maker Pearson is also getting in on the action by developing adaptive learning software and launching virtual tutors for students as they “read” through digital textbook resources.

      Ok, here I'm getting a bit more worried. It's not that I don't think this is helpful. But I do think it's skipping some possible better, more human solutions.

      One concern: the premise here is that comprehension struggles are mostly questions requiring answers rather than discursive situations requiring more interaction. A second related concern: is the ultimate goal of "learning" to get the answer or to acquire facility with that discursive process? (Answer: the latter.)

      I think simple social annotation, perhaps backed by some AI, could go a long way here. Allow students to ask questions, answer each others questions, and surface those questions and answers in a useful way to teachers...

    1. An overwhelming number of companies (64%) indicated that their number one reason for implementing social tools is to support a culture of learning. The next two main motivations are to encourage collaboration and innovation (54%) and connect employees to organization experts (42%).

      Main motivation for adoption of workplace social learning tools.

    1. Learning paths allow you to assemble two or more courses into a path that students must complete to trigger completion actions.
    2. I think a lot of faculty are still at the point where they need a stack of papers and red pen.

      Emphasis on “still”. Direction of change?

    1. Could different co-teaching and collaborative course approaches or more modern pedagogical practices move the needle more than the latest LMS features? 
    2. LMSs limit the visibility of copyrighted course content to only course participants for the duration that they need it. (Of course, this would become a moot point if using openly licensed OERs.)
    3. Over the course of many years, every school has refined and perfected the connections LMSs have into a wide variety of other campus systems including authentication systems, identity management systems, student information systems, assessment-related learning tools, library systems, digital textbook systems, and other content repositories. APIs and standards have decreased the complexity of supporting these connections, and over time it has become easier and more common to connect LMSs to – in some cases – several dozen or more other systems. This level of integration gives LMSs much more utility than they have out of the box – and also more “stickiness” that causes them to become harder to move away from. For LMS alternatives, achieving this same level of connectedness, particularly considering how brittle these connections can sometimes become over time, is a very difficult thing to achieve.
    1. out of 878 potentially relevant studies published between 1992 and 2017, only 36 directly compared reading in digital and in print and measured learning in a reliable way. (Many of the other studies zoomed in on aspects of e-reading, such as eye movements or the merits of different kinds of screens.)

    1. This is a very easy paper to follow, but it looks like their methodology is a simple way to improve performance on limited data. I'm curious how well this is reproduced elsewhere.

    1. The embedding of maker culture in K–12 education has made students active contributors to the knowledge ecosystem rather than merely participants and consumers of knowledge.

      How does this get balanced with privacy concerns? I have yet to see an argument or practice that successfully navigates this tension?

    1. This has much in common with a customer relationship management system and facilitates the workflow around interventions as well as various visualisations.  It’s unclear how the at risk metric is calculated but a more sophisticated predictive analytics engine might help in this regard.

      Have yet to notice much discussion of the relationships between SIS (Student Information Systems), CRM (Customer Relationship Management), ERP (Enterprise Resource Planning), and LMS (Learning Management Systems).

    1. “Programming is like thinking about thinking. And debugging is a close approximation of learning about learning.” When you program, you translate your thoughts into executable form. Debugging your program is close to debugging your thoughts.
    2. The thrill of programming, for me, is found more in the exploration of ideas than in the joy of controlling machines.

      This is something that I can relate to. I tend to program as I learn a subject that I eventually want to write real programs for, as an aide to understanding. It helps me grok how things work in the new domain. It also helps me retain the new information.

    1. Project-based learning typically is grounded in the following elements: Role-playing Real-world scenarios Blended writing genres Multiple reading genres Authentic assessments Authentic audiences Real-world expertise brought into the classroom Units that assess multiple skills Units that require research and comprehension of multiple subjects Student choice Collaboration Multiple methods of communication (writing, oral speaking, visual presentations, publishing, etc.)

      A good overview of the elements of PBL.

    1. Inside Digital Learning asked four authors of books about online education for their expert advice on how instructors and their institutions can excel in virtual course instruction. The authors agreed that the online classroom is different enough from the traditional one that faculty members and adjuncts need to create courses for digital delivery that are substantially different from those they teach on campus. And they said teaching online requires an even keener focus on student engagement than the face-to-face model does.

      The article outlines 7 basic tips for instructors teaching online: make it a group effort, focus on active learning, chunk the lessons, keep group sizes small, be present, parse your time and embrace multimedia assignments.

    1. Dysfunctional relationships at work are as damaging to goal achievement as challenging children in the classroom.

      Social-emotiobal learning is more important than any other subejct taught in class

    1. it can realize an open connection with the outside world

      Knowledge online, not behind a paywall. Available to all if you know where and how to look for it. Opens doors and clarifies paths. Robert Schuwer.

    1. Connected learning is when someone is pursuing a personal interest with the support of peers, mentors and caring adults, and in ways that open up opportunities for them

      Support is essential

    2. The “connected” in connected learning is about human connection as well as tapping the power of connected technologies.

      I found this very true for languages learners, specially foreign languages. The purpose of language is comunication, for a foreign language classroom, conections to real people gives meaning to the class and those connections would not be possible without the use of technology.

    3. Connected learning isn’t a burden that one organization shoulders on its own, and is about building connections across different sites of learning

      This is where the community partnerships come in

    4. Traditional education is failing to engage many students as they enter their middle school, high school, and college years.
    1. In math, four times a year, each student is given a set of values or codes to substitute in the equations so that even though the students are working together, they have to focus on the mathematical process and not just the “right answer.” In English, the discussions are open-ended, allowing for multiple right answers.

      Yes! This is how I plan to teach science. I will give them questions but they have to find the answers.

    1. Connected learning posits that by connecting and translating between in-school and out-of-school learning, we can guide more young people to engaging, resilient, and useful learning that will help them become effective contributors and participants in adult society. We also believe that networked and digital technologies have an important role to play in building these sites of connection and translation
    2. onnected learning is realized when a young person is able to pursue a personal interest or passion with the support of friends and caring adults, and is in turn able to link this learning and interest to academic achievement, career success or civic engagement.

      Essentially, this is conecting personal interests to content learning to real world applications.

    1. participants spent almost 40 minutes out of every 100-minute class period using the internet for nonacademic purposes

      There'll be times when I explicitly say, pull out your laptops if you have them, and we use them in class. And other times I explicitly say, close your screens. Either way, this stat here is well worth sharing with students at the start of the semester.

    1. Email does not afford synchronous communication in the way that a phone call, a face-to-face conversation, or instant messaging does. Nor does email afford the conveyance of subtleties of tone, intent, or mood possible with face-to-face communication.

      extremely important when "negocioation of meaning" is at play

    1. Language, to me, is a mystery because I haven’t studied it but, I know there’s loads of literature out there, and we know in general that kids learn language differently from adults and that people can learn a language by immersion rather than by any direct instruction in grammar or anything. It’s interesting that the term literacies is used with reference to language acquisition, and we use it in digital literacies. One common aspect of literacies which also came up in earlier conversations with Sally, was my belief that digital literacies could only be (really) learned socially, as with language.

      Cognitive skills vs Physical skills when learning languages

    1. Reciprocity now becomes a matter of at once mutually preserving the other’s distinctness while interdependently fashioning a bigger context in which these separate identities interpenetrate…are co-regulated, and to which persons invest an affection supervening their separate identities. Reciprocity now becomes a matter of both holding and being held, a mutual protection of each partner’s opportunity to experience and exercise both sides of life’s fundamental tension.”

      Lv5 reciprocity: Maintaining individual's distinctness while together create a bigger context so that these separate identities interpenetrate.

    2. As the institutional balance breaks, the person becomes more available to and interested in a kind of sharing and intimacy with others. But intimacy in the next balance is the self’s aim, rather than its source. It involves a self that travels between systems, or exists in the dynamism between them, not in the dynamism between individuals.

      The self exists in the dynamism between systems, not between individuals

    1. Postmodernism (or “poststructuralism”), in its denial of the possibility of judgement and rejection of all “metanarratives” (grounded systems), corresponds to the stage 4.5 nihilistic gap.

      Post-modernism: stage 4.5 nihilistic gaps aka the "sadness" after seeing the truth in Plan B by Charles Inouye

    2. All ideologies are relativized as tools rather than truths. Fluidity treats rationality as a valuable tool that is not always applicable; non-rational ambiguity and paradox become non-problematic. Stage 5 can, therefore, conjure with systems, as animated characters in a magical shadow-play drama.

      All ideologies are relativized as tools rather than truths. "Conjuring" with systems, shadow-play drama.

    3. To stage 3, that sounds cold and distant, but for stage 4, it means seeing the other person for who they really are. Emotions are just something people have, from time to time. Those need to be dealt with, but should not be taken too seriously. Relating to the other person’s principles, projects, and commitments means supporting what they most care about in the longer run. A romantic relationship between systematic people not only tolerates, but respects, and actively supports, their differing values and projects. That is what it means (for stage 4) to be actually in a relationship with another person, rather than losing both your selves in a warm bath of shared feelings.

      Being in relationship for Stage 4: dealing with but not taking emotions seriously. Must support differing values & projects.

    1. Legitimate peripheral participation is a more powerful motivation for accurate feedback than money. If a student’s labor contributes to the success or failure of your project, you want to be sure they are doing it right—and so you will scrutinize their work carefully, and give detailed corrective advice.

      Why does boss care about giving feedback in Legitimate Peripheral Participation? Coz it's success or failure! (FAIL = For All I Learn)

    1. The University of Michigan Teach-Out Series offers an opportunity for learners around the world to come together with our campus community in conversation on topics of widespread interest.

      Short, 1-week, open courses offered on edX that explore timely topics

    1. Thisstudyexaminesthecomponentsofaself-pacedonlinecoursespecificallydesignedtoincorporateweb-basedpedagogytocreateanengaginganddynamiclearningenvironment.Itcomparesstudentperformanceinaself-pacedonlinecourse,aconventionalonlinecourseandatraditionalin-classcourseandrevealsthepotentialforstudentstothriveinawidevarietyofonlinecourseformats

      This study compares performance in a face to face, online and strategically designed self-paced online course. The results showed small performance improvements for the self-paced students compared with the face to face students and larger improvements when compared to the instructor paced online course. The researchers speculate that the increased flexibility allows learners to achieve maximum performance, but this result could also be attributed to the design improvements. They discuss the design improvements made to the self-paced course, but do not share any information about the design of the face to face or instructor paced online courses. It would be interesting to see if design improvements in those formats that provided the same opportunities for interaction and feedback would change the results.

    1. It used rich media and a mix of traditional and emerging asynchronous computer-mediated communication tools to determine what forms of interaction learners in a self-paced online course value most and what impact they perceive interaction to have on their overall learning experience. This study demonstrated that depending on the specific circumstance, not all forms of interaction may be either equally valued by learners or effective.

      The results show that students most highly value interactions with the instructor and content.

    1. If it can be established that student self motivation has a direct effect on remediation, it stands to reason that by finding a way to increase a student’s self motivation, the remediation process can be improved to increase the likelihood of success for a student who requires the use of remedial courses in the specialized classroom setting. Attempting to understand the factors that create a learning environment of poor motivation is an arduous task, but attempting to improve those factors that increase motivation is imperative.

      This study involves a self-paced developmental mathematics course (N=86). The results showed that the students' perceived intrinsic value of the learning was a significant predictor of success in the course. Motivation had a greater impact on students' ability to succeed than prior knowledge (based on ACT math scores).

    1. ne critical element in the effectiveness of these networks is “working in the open.” This includes a number of simple practices commonly associated with open source software: making curriculum and tools easy for others to discover; publishing using an editable format that allows others to freely use and adapt them; using an open license like Creative Commons. It also includes a set of work practices that make it easy for people to collaborate across organizations and locations: collaborative writing in shared online documents; shared public plans on wiki or other editable documents; progress reports and insights shared in real time and posted on blogs. These simple practices are the grease that lubricates the network, allowing ideas to flow and innovations to spread. More importantly, they make it possible for people to genuinely build things together—and learn along the way. This point cannot be emphasized strongly enough: when people build things together they tend to own them emotionally and want to roll them out after they are created. If the people building together are from different institutions, then the innovations spread more quickly to more institutions.

      These are all important aspects of open pedagogy, imo. Transparent, network practices that connect, but also create space and opportunities for particiaption by those on the edges. Working in the open is an invitation to particiaption to others.

    2. Rather than selecting a single organization to lead the network, consider a spoke-and-hub or constellation model that empowers teams of organizations to act as “network hubs” for different sectors of the network. The best candidates for these hubs are intermediary organizations that act in the best interests of the network, allowing other network members to focus on their core mission and programmatic activities. Hub organizations play several roles. As conveners, they bring people together and build the field. As catalysts, they invest money and resources to get new ideas off the ground or help exciting projects to develop. As communicators, hub organizations enhance networks members’ ability to tell their story effectively and efficiently, internally and externally. As champions, hubs lift up the accomplishments of network actors, regionally, nationally, and internationally. And, as coordinators, hub organizations connect the dots, recommend priorities for the network, and connect those priorities to national resources.

      This could describe BCcampus - a hub organization that connects networks

    1. TPS Reflective Exercises

      TPS as metacognition - worth trying out. Would have to budget time for it. Could we combine it with something to capture data? connect to qualtrics or google forms

    1. Detection of fake news in social media based on who liked it.

      we show that Facebook posts can be classified with high accuracy as hoaxes or non-hoaxes on the basis of the users who "liked" them. We present two classification techniques, one based on logistic regression, the other on a novel adaptation of boolean crowdsourcing algorithms. On a dataset consisting of 15,500 Facebook posts and 909,236 users, we obtain classification accuracies exceeding 99% even when the training set contains less than 1% of the posts.

    1. Obviously, in this situation whoever controls the algorithms has great power. Decisions like what is promoted to the top of a news feed can swing elections. Small changes in UI can drive big changes in user behavior. There are no democratic checks or controls on this power, and the people who exercise it are trying to pretend it doesn’t exist

    2. On Facebook, social dynamics and the algorithms’ taste for drama reinforce each other. Facebook selects from stories that your friends have shared to find the links you’re most likely to click on. This is a potent mix, because what you read and post on Facebook is not just an expression of your interests, but part of a performative group identity.

      So without explicitly coding for this behavior, we already have a dynamic where people are pulled to the extremes. Things get worse when third parties are allowed to use these algorithms to target a specific audience.

    3. any system trying to maximize engagement will try to push users towards the fringes. You can prove this to yourself by opening YouTube in an incognito browser (so that you start with a blank slate), and clicking recommended links on any video with political content.

      ...

      This pull to the fringes doesn’t happen if you click on a cute animal story. In that case, you just get more cute animals (an experiment I also recommend trying). But the algorithms have learned that users interested in politics respond more if they’re provoked more, so they provoke. Nobody programmed the behavior into the algorithm; it made a correct observation about human nature and acted on it.

    1. areas where deep learning is currently being poorly utilized

      who is curating a list of deep learning success stories, case studies and applications?

    2. highly automated tools for training deep learning models

      such as?

    3. The best way we can help these people is by giving them the tools and knowledge to solve their own problems, using their own expertise and experience.

      Agree or disagree?

    1. Appendix A:Table of various deep learning applications

      This is a good list. Has anyone come across a comprehensive list of deep learning applications?

      new Connected Learning Lab (CLL) at UC Irvine, an interdisciplinary research center dedicated to studying and mobilizing learning technologies in equitable, innovative, and learner-centered ways.

    1. Almost all exciting results based on recurrent neural networks are achieved with them.

    1. In turn, this child’s statement may shift the teacher’s learning and encourage her or him to recreate or extend this same experience to another area of study in the curriculum.

      I hadn't thought about this aspect of discourse: not just the various context the content but of the experience of learning itself, how a teacher responds to student work, how that work is set up in the first place.

      I think hypothes.is is particularly useful in relation to this type of context in the way it makes certain previously hidden aspects of learning visible...

    1. If we write that out as equations, we get:

      It would be easier to understand what are x and y and W here if the actual numbers were used, like 784, 10, 55000, etc. In this simple example there are 3 x and 3 y, which is misleading. In reality there are 784 x elements (for each pixel) and 55,000 such x arrays and only 10 y elements (for each digit) and then 55,000 of them.

    1. the area under the curve (often referred to as simply the AUC) is equal to the probability that a classifier will rank a randomly chosen positive instance higher than a randomly chosen negative one (assuming 'positive' ranks higher than 'negative')

    1. Thanks for letting me take this feldgang. A feldgang is what farmers do all the time. Fieldwalks

      Fortunately you did.

      This is enabling me to continue my feldgang here.

    3. I freely admit that this is a mess of post

      learning

    1. I was in the room with him from my learning space in Clermont Ferrand. I could hear the bad acoustics of the room in which he was/we were?. We were sharing the slides on the screen in Krakow inside the slide share of our hangout on air.

      Social presence.

      Hybridization.

      Room, space. confusion

    1. Students need learning goals, and they need to set these for themselves.

      Again, assumes quite a bit of freedom on the part of the students. Institutional goals/outcomes or disciplinary goals/outcomes that have to be included?

    2. There is probably no need to release all the content at once. Doing so (to the tune of about 15 weeks worth of content) could be way overwhelming for any student. Releasing all the content at once around a very specific chunk of the course makes the most sense.

      Chunked release of information--here's everything we're doing for unit 2, for example? Or two weeks' worth because things are additive/scaffolded?

    3. For the most part, I made myself go through the modules in the order in which they were created. I assumed they were placed in that order for a specific reason. If I hit content I already knew or didn’t want to apply just yet then I skipped over it to return to later if needed.

      This is a lot of faith in the instructor (and not necessarily misplaced). It also requires a certain level of pre-existing familiarity to make those decisions about what is/is not useful and a certain intention in taking the course (i.e., there won't be an exam and the course is mostly voluntary).

    1. The words of one of my students, one of my fellow learners helped me continue. Those words, some of them, are translated here in this post Nagasaki mon amour.

      There is no going back. We must go forward.

      The key issues concern the data collection/policing of our conversations.

    1. trying to answer questions—or to even foster questions in the first place

      This strikes me as a crucial point: using this tool allowed you to shift from a traditional, considerably passive learning style (they're still engaging with the text, but alone) to a more potentially active one.

    1. Frankly, it didn't really make an impression on me at all until I started writing this retitled post spurred by Frances Bell's "Reflections on Community in #Rhizo14 - more questions than answers."

      nonlinear connection emergence

    1. Res ear ch often isolates particular pieces of the complex puzzle in order to study them in detail. However useful this may be, it obscures the dynamism of the actual teaching and learning work that goes on, and cannot show the emergent and contingent nature of that work

      So is one example of this the teaching of vocabulary and grammar out of context of authentic reading and conversation?

    2. There must be room in a learning environment for a variety of expressions of agency to flourish.

      Love this.

    3. However, in order to make significant progress, and to make enduring strides in terms of setting objectives, pursuing goals and moving towards lifelong learning, learners need to make choices and employ agency in more self-direct ed ways.

      This is just what Naoko is doing by allowing students to choose their topics of research within the context of a language learning course.

    4. Agency is therefore a central concept in learning, at many levels an in many manifestations. It is a more general and more profound concept than the closely related terms autonomy, motivation and investment. One might say that autonomy, motivation and investment are in a sense products (or manifestations) of a person’s agency.

      Interesting.

    5. the multilayered nature of interaction and language use, in all their complexity and as a network of interdependencies among all the elements in the setting, not only at the social level, but also at the physical and symbolic level

      Does this map to literary theory in any way?...

    6. any utterance can carry several layers of meaning

      And all those layers can be visualized through annotation: vocabulary, cultural context...

    7. “layer ed simultaneity.”

      Love that phrase.

    8. I like to use this image to illustrate that any utterance has a number of layers of meaning. It refers not only to the here and now, but also to the past and the future of the person or persons involved in the speech event, to the world around us, and to the identity that the speaker projects.

      Wow. Annotation fits quite nicely here as helping to visualize these layers in a slightly more user-friendly way than Escher.

    9. and they are dynamic and emergent, never finished or absolute.

      Come on, "not-yet-ness" (Collier).

    10. ecologically valid contexts, relationships, agency, motivation and identity.
    11. ecological perspective,

      Everything is inter-related. Language cannot be learned out of context, out of community.

    1. Learningto complete a whole task involves four levels ofinstruction: (a) the problem, (b) the tasks re-quired to solve the problem, (c) the operationsthat comprise the tasks, and (d) the actions thatcomprise the operations. Effective instructionshould engage students in all four levels of per-formance: the problem level, the task-level, theoperation-level, and the action-level.

      Steps is learning to complete a whole task. This could be an extension of our matrix.

    2. Van Merriénboer (1997) recommendedthat the first problem in a sequence should be aworked example that shows students the type ofwhole task that they will learn to complete.

      This is a great way to communicate/model a learning outcome.

    1. Adaptive Learning is data-driven and continually takes data from students and adapts their learning pathway to “change and improve over time for each student”.
    1. Consequently, our advice is simple: continue to train your networks on a single machine, until the training time becomes prohibitive.

      一定要对 数据加载时间、参数通信时间、计算时间有个明确的评估,不能为了并行而并行。能单机解决的问题就不着急上多机。

    2. odel parallelism can work well in practice, data parallelism is arguably the preferred approach for distributed systems and has been the focus of more research

      why ?
