    1. A JavaScript DOM model supporting element creation, diff computation and patch operations for efficient re-rendering
    2. virtual-dom exposes a set of objects designed for representing DOM nodes. A "Document Object Model Model" might seem like a strange term, but it is exactly that. It's a native JavaScript tree structure that represents a native DOM node tree.
    3. virtual-dom is a collection of modules designed to provide a declarative way of representing the DOM for your app. So instead of updating the DOM when your application state changes, you simply create a virtual tree or VTree, which looks like the DOM state that you want. virtual-dom will then figure out how to make the DOM look like this efficiently without recreating all of the DOM nodes.
    1. The Shadow DOM is a browser technology designed primarily for scoping variables and CSS in web components. The virtual DOM is a concept implemented by libraries in JavaScript on top of browser APIs.
    2. Since “virtual DOM” is more of a pattern than a specific technology, people sometimes say it to mean different things. In React world, the term “virtual DOM” is usually associated with React elements since they are the objects representing the user interface
    3. The virtual DOM (VDOM) is a programming concept where an ideal, or “virtual”, representation of a UI is kept in memory and synced with the “real” DOM by a library such as ReactDOM.
    1. Strategies for Virtual Learning Environments:Focusing on Teaching Presence and TeachingImmediacy

      Through a literature review of 50 articles published between 2003-2014, the authors explored aspects of online learning (teacher presence, teacher immediacy) that impact learner interest and motivation in the online environment. Recognizing that these aspects are key, the authors explore various approaches to retention the virtual setting. The multifaceted role of the instructor is reviewed as well as virtual facilitation strategies. The literature search revealed a positive correlation between teaching presence, teaching immediacy, and learner engagement and motivation. 6/10

    1. React creates a virtual DOM. When state changes in a component it firstly runs a “diffing” algorithm, which identifies what has changed in the virtual DOM. The second step is reconciliation, where it updates the DOM with the results of diff.The HTML DOM is always tree-structured — which is allowed by the structure of HTML document. The DOM trees are huge nowadays because of large apps. Since we are more and more pushed towards dynamic web apps (Single Page Applications — SPAs), we need to modify the DOM tree incessantly and a lot. And this is a real performance and development pain.The Virtual DOM is an abstraction of the HTML DOM. It is lightweight and detached from the browser-specific implementation details. It is not invented by React but it uses it and provides it for free. ReactElements lives in the virtual DOM. They make the basic nodes here. Once we defined the elements, ReactElements can be render into the "real" DOM.Whenever a ReactComponent is changing the state, diff algorithm in React runs and identifies what has changed. And then it updates the DOM with the results of diff. The point is - it’s done faster than it would be in the regular DOM.

      React creates a virtual DOM and every time the state of a component changes, it runs a diff algorithm on the virtual DOM. If something needs to be changed, it changes only this part in the HTML DOM. This is faster than the default of updating the entire HTML DOM any time something changes.

    1. When in need of help, students reread directions, checkwith Home-Group members (3-4 students who are inschool or at home on the same days), check the digitalPeer Expert Board, and then put their name on the digitalHelp Board

      This is a fantastic idea for building community.

      Facilitate in Google? Allow edits on a Canvas page? What about multiple editors?

      • Google Slides parking lot embedded on the homepage
        • Each student has a slide they edit
        • General questions slide for help requests
    2. review teacher notes and the schedule theydesigned for themselves for the week,

      Students are dictating the pace and the content they're working on. The teacher is helping to curate and interpret those materials as students work through the idea.

    3. Curate an instructional plan forstudents, whether at home orschool, that will addresscognitive, learning style, andcultural differences.

      I don't remember where it was, but someone suggested a 5:1 prep:teach time ratio. Spend far more time prepping (researching, finding resources, etc) than you do actually teaching students verbally so you have several items to incorporate or fall back on.

    4. BenchmarkDiscussion

      What is a Benchmark Discussion? Why is it capitalized?

    5. Students continue working ondifferentiated learning activities.(Remote only? Hold discussionswith half of the class at a time.)

      Sounds like great use of a fishbowl model.

    6. socially-distanced in-school students andat-home students can join

      Use the tools that are available to make the in-person material as accessible as possible to the at home students.

      • iPad as a document camera
      • AirServer to the board, share screen to Meet

      Repeat the sessions on A/B days? One day per week for these sessions?

    7. Students access an Activity List

      Weekly planning is critical. This helps the teacher provide consistent, supportive instruction and it helps the student regulate their work.

      Having minimesters this term will help students focus.

    8. indicate they arepresent

      What are some simple ways to indicate they're present?

      • Google Form with email automatically collected?
      • Canvas survey with a simple get to know you question?

      Something independent that can build self-regulation skills and habits.

    9. I recommend a cloud-baseddocument where students can post their thoughts or comments (in-school and at-home students) so thatthe teacher can follow the discussion

      Backchanneling - or doing something like a remote fishbowl discussion - can help facilitate the physical gap for students at home vs in class.

      • How can we explore bringing in home/school students at the same time? Try with the ambassadors?
    10. Time with the teacher “live” shifts to these Small-Group, Mini-Lessons and live discussions whereteachers can engage students in collectively grappling with content.

      Time is spent talking with one another, not a teacher talking at a group of students.

      Separate yourself out of time constraints by providing familiar instruction materials (ie, video) ahead of the small group meeting so the group time is as effective and focused as possible.

    11. Whole-class lessons across video, sometimes called “live streaming,” are not effective -- I won’teven sugar-coat that

      There are too many unknown factors involved in expecting every student, in vastly different home situations, to engage equally in a given situation.

    12. Teachers need to avoid reserving in-school days for lessons andteacher talk, thus, robbing students of the socialization skills they are craving

      When you're together, it's time to listen to what students are saying rather than talking at them even more.

      see Dan Meyer: https://blog.mrmeyer.com/2020/but-artichokes-arent-pinecones-what-do-you-do-with-wrong-answers/

    13. We cannot afford to depend on in-school time for lessons and at-home time only forpractice.

      This is a remnant of the old model of schooling which needs to be foregone in favor of better models, more suited to flexible learning environments.

    14. The key to a successful hybrid learning environment is implementing structures and strategiesthat work as well at home as they do in school, such that learning continues whether at home orat school -- no need for a change in methods with a change in setting

      These should be based on skills students already have or which can be developed independently (or with limited, in person support).

    1. Then there is the option of getting students to talk to each other online on discussion boards and videoconferences. Some students adapt to it quickly and like it. Some don’t, because it feels impersonal. You have to be patient with that and give them some time and space to adjust.

      Introverts v extroverts. Oil and water. They've always differed, always will. Maybe this virtual, personalized learning movement will finally allow introverts to stop feeling so defeated in the presence of extroverts who live so much more loudly than they do. Finally, they'll be able to live peacefully in their own mind, undisturbed by the stress of feelings like you need to be more extroverted to fit in.

      Btw: I'm not encouraging each party to distance themselves from each other all the time. What I am saying is that when value is trying to be distributed, distribute it however it'll best be received. Then, later, once teaching time is over, they can socialize in traditional ways... IF that's what they want to do.

    2. Rizga: How have you been translating this online?Moore: It depends on the student. Some students work very well asynchronously. They are very comfortable working alone on a draft; I make color-coded comments in a word document or their PDF, and then I send it back. Some students need me to explain things to them in person before I send them the comments; we’ll do a video or audio chat. Others need even more interaction: I’ll hook them up to a videoconference, and we’ll go through all the comments together. Some students I need to refer to a grammar-brushup program or a YouTube video on how to do some of the mechanical stuff like uploading papers online.

      Sounds like Mrs. Moore deserves a raise! This woman knows what's up! She represents the future while living in a community that (probably) latches on to tradition.

      Any of you big city school systems reading this? If you are, hire her. You can probably pay her less than what your other teachers are earning and still give her a bump in pay compared to what she's earning in Mississippi.

    1. In the text by Jennifer Herseim, virtual reality (VR) is identified as a tool to help with teacher training. Teachers can embark on a learning process in a secure environment with a diverse set of student avatars operated in part, by a real individual. Staff can explore their teaching methods and styles with recorded and measured skills and responses for future review and reflection. Rating 7/10

    1. Playing games with my brother taught me that connections can be made with another person through virtual reality. Things like cooperation, shared problem-solving, and communication in gaming can strengthen relationships. Most importantly, gaming taught me that no matter the differences between me and another person, we can find common ground through play.
    1. Virtual reality meets this bar when it comes to one-on-one conversations: when we analyzed the EEG results of participants who chatted in virtual reality, we found that on average they were within the optimal range of cognitive effort. To put it another way, participants in virtual reality were neither bored nor overstimulated. They were also in the ideal zone for remembering and processing information.
    1. But augmented reality, as the name suggests, is about augmenting or adding to reality reality. You might be looking at your cat or up your street, but there could be digital characters and content overlaid on them.

    1. Towards a Mobile Augmented Reality Prototype for Corporate Training: A New Perspective

      Research Article. I found this article especially interesting because it promotes the use of mobile devices for online learning. This focuses on corporate training, but it is easy to see how it could be applied across areas and fields. There is a specific focus on the use of virtual and real objects during education experiences to create experience-based learning outcomes. Rating 4/10

    1. Becoming posthuman means exceeding the limitations that define the less desirable aspects of the “human condition.” Posthuman beings would no longer suffer from disease, aging, and inevitable death (but they are likely to face other challenges). They would have vastly greater physical capability and freedom of form

      Posthuman beings contradict the human conditions that apply to my life, and every living being for that matter: immortality is non-existent. The passage alludes that the posthuman evolution will oppose the current human condition, and humanity will be redefine its physical form. A reformation in the modern humans understanding of scarcity is entirely different than that of the posthuman. With increased control over the posthumans physical capability are differing in juxtaposition to the human condition in the twenty first century: Prompting our modern society with the question of whether the human condition makes significant biological changes. The change from the former to the latter intertwines technological advancements with physical capabilities, although to what end? The human condition will be a backbone to the technology that manages the posthumans interpretation of reality.

    1. Finally, Thorseth points out that Kant’s notion ofreflective judgment is ofpossiblejudgments, in con-trast with actual judgments – where the former referto something virtual in the sense of what ispossiblefor human beings to imagine. For Thorseth, the well-known virtual world of Second Life stands as anexample of a virtual reality in which a key conditionof reflective/possible judgment is met – namely, thatwe are able to avoid the illusion that our purely pri-vate and personal conditions somehow constitute anobjective context or reality

    1. The virtual is never the opposite of the actual—it is how the actual resonates beyond the limits of its actualization. It is the red-ness and warmth in the foregoing example.

    1. I worry that the industry has no idea how much research already goes on, or how vital it is to fund.

      Maybe my fears are unfounded, but the stakes are high. Startups are the very tip of the iceberg, floating by virtue of work that was done by other people long ago. If people forget we need to fund research now, we’re going to feel it decades later and not know why. Imagine where we’d be without the government-funded research of the 60s!

    1. Pixar Animation co-founder Ed Catmull has warned that virtual reality technology may not be the revolution in storytelling that some of its evangelists have claimed. “It’s not storytelling. People have been trying to do [virtual reality] storytelling for 40 years. They haven’t succeeded. Why is that? Because we know that if they succeed then people would jump on it.”

      What? Who says VR has to be "just wandering around in a world"? You don't have to give the viewer full mobility, or any mobility. You can put their point of view where you want, and disallow interaction with the scenery -- which makes the experience precisely a 3D immersive motion picture. And I'm sure scripted stories can be told while giving the viewer some interaction with characters, and much freedom to move around -- that's just trickier. You'd plan for all the characters in various locations to push the story in a particular direction, or one of several directions, regardless of what the viewer does. The more you let the viewer affect events, the more it becomes a game, rather than a story.

    1. Removing the VR goggles, the adrenaline continues to course through me. I have only been inside the Project Syria immersive for a few minutes, but the effect is dramatic. It was commissioned for the 2014 World Economic Forum in Davos to give politicians an insight into everyday life in Syria. And it works.
    1. "You will have a pair of sunglasses, and you can switch it from glasses mode, to VR mode as you wish. The VR will expand to fill your field of vision, or you can watch it in a little window.” This device of the future will not only bring virtual reality into our everyday lives, according to Urbach, but also destroy the primary way we use many other electronics. “You’ll be done with any other screen,” he says. “You won’t need it. It will be generated on a surface in the air. Put your finger over your palm, it’s a phone. Your desk becomes a laptop. "The resolution two generations from now will give you a 4K experience, so you probably won’t go to a movie theater. Why would you buy a wall-sized TV?”

    1. Indeed, it was often unclear from the level of engagement which participants were physically present at DPL and which were watching from afar. The present-absent-present dance was fascinating to observe.

      As a "virtual attendee" or "lurker" or "scoper," it was difficult to follow and frustrating at times, but super helpful and fun too, especially as resources (images, links, quotes) were shared out. Communicating the context of those resources is still a pretty tricky thing to do well.

    1. The real advantages that the VRVO offers to science and to its sponsors are based on the fact that it is not a funded project or center, and that the difference between it and funded centers (or facilities, or projects) is intentional and generative to its ROI.

      The simple point here is that you want to create a volunteer-run organization to do those things that are really easy for this type of organization to do, and really hard to fund directly.

    1. There’s a certain anxiety in the VR community that surfaces in many conference panels and interviews with industry leaders: plenty of veterans are worried that this latest flowering of the technology will end with the same commercial disappointment that we saw in previous decades.

      Why do we care about whether it's a commercial success?
