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.

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

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).

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.

This could describe BCcampus - a hub organization that connects networks

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

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.

Needs to focus on practice not policy - Perhaps consider adding in Social learning ? Julian Stodd's work around social leadership? https://julianstodd.wordpress.com/2016/02/23/10-things-a-social-leader-does/

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

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.

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.

lstm是rnn的一种，但是一般所RNN指传统标准的RNN

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...

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.

Social presence.

Hybridization.

Room, space. confusion

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?

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

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).

There is no going back. We must go forward.

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

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.

nonlinear connection emergence

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

Love this.

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

Interesting.

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

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

Love that phrase.

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

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

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

Robert Mercer, Steve Bannon, Breitbart, Cambridge Analytica, Brexit, and Trump.

“The danger of not having regulation around the sort of data you can get from Facebook and elsewhere is clear. With this, a computer can actually do psychology, it can predict and potentially control human behaviour. It’s what the scientologists try to do but much more powerful. It’s how you brainwash someone. It’s incredibly dangerous.

“It’s no exaggeration to say that minds can be changed. Behaviour can be predicted and controlled. I find it incredibly scary. I really do. Because nobody has really followed through on the possible consequences of all this. People don’t know it’s happening to them. Their attitudes are being changed behind their backs.”

-- Jonathan Rust, Cambridge University Psychometric Centre

Which assessment? Analytics aren't measures. We need to be more forthcoming with faculty about their role in measuring student learning. Such as, http://www.sheeo.org/msc

It's not "mastery of content" it's mastery of the skills to engage with content.

I'm curious how platforms like Hypothesis, and more broadly the social practices afforded by open annotation, help create the conditions for new types of professionally-relevant (online) forums. I think a stance toward engagement with the political dimensions of learning is complementary to the work organizations like Hypothesis who are building tools and partnerships for a more democratic, peer-reviewed web. https://youtu.be/QCkm0lL-6lc

One means of engaging such dialogue is through the public annotathon scheduled for February 27th through March 3rd, and which will occur right here - in the margins of this pre-print turned blog post. See my post for more information about the annotathon, and how to join and use Hypothesis.

Morris Pelzel on Doug Engelbart's Augmenting Human Intellect: A Conceptual Framework.

the presentation and arrangement of symbolic data is crucial, and any given arrangement may be more or less conducive to discovery. That is why Engelbart’s observation about “playing” with and “rearranging” the materials we are dealing with strikes such a resonant chord. Even if we are only dealing with text, the ease of recombining and manipulating our words and phrases enables our writing to more quickly reach a suitable form of expression.

as we are social animals, our intellects work most effectively, not in isolation but in connection with others. When thoughts and ideas are externally represented, they thereby enter to some degree a public space,

Gardner Campbell on Doug Engelbart's Augmenting Human Intellect: A Conceptual Framework.

even as modes of comprehension increase for some, modes of incomprehension increase for others. The person who sits with “Joe” as Joe demonstrates his new symbol-manipulating capacities reacts in ways that many of us may recognize

...

It takes humility, and hospitality, to spend time with new ideas ... to go deep and go long with concepts that ask us to re-examine many things we take for granted.

This and the next activity are good to explore diverse identities – or uniformity of some identity dimensions – in a group.

That's probably something like this: https://www.mnscu.edu/system/equity/documents/Danger%20of%20a%20single%20story%20circle%20handout.pdf

-> or see p. 16

Good activity to explore the multiple identities, combinations of identities, and intersectionalities of individual persons. Use?

Shared Writing: This seems particularly useful for online conversations that are asynchronous, as it is based on reading statements, commenting on them, and passing the comments around.

Like this one, particularly if quotes are well-chosen, especially in a larger group that otherwise has not done much reading/thought about questions of privilege, discrimination, and marginalized experiences.

I like this activity if the aim is to make personal connections and get to know the individuals involved in a learning group. As a result, probably best for a small group. Requires some preparation as participants have to be asked to bring an object to the meeting.

Interesting activity. Question: Is this useful in a larger group, or only in a smaller group? The calling-out portion enables people to participate without talking, which accommodates larger numbers; but the exposure can be intimidating – particularly for students, who then may just stay put. Maybe start with "easy" identity groups – sports team supporters? – that people are willing to show? Or would this undermine what the conversation should be about?

The discussion portion may get out of hand in a larger group; may need subgroup formation.

Open pedagogy? No. Public Pedagogy maybe. Is public pedagogy a thing?

Nice ¢25 word, here. Means "raised," as in embossed letters or bas relief. Pronounce "reh-LEE-vo," in case you, like me, need to pepper your conversation with unnecessary ornateness because you, like an Athenian, like to dazzle through "showy but false eloquence."

How does study this account for other cues of perception? e.g. listening and such. Isn't it biased against Visual only?

It is part of the Interference Theory. See more here: https://en.wikipedia.org/wiki/Interference_theory

I'm not picking up the meaning of this sentence. Thinking back to my younger years and different child studies, I assumed children learned by seeing, not comparison. If they are comparing, what are they comparing?

You had me already at the Coffee Cup picture over the equations! :)

YES! Why are they taken away? We can add to this list coding, programming, renewable energies, and maybe even gardening. These will be the sustainable skills of the future.

Entirely because they are able to make neural connections which solidify and anchor learning in long-term memory. Student attention spans and interest have skyrocketed in classrooms with coding, robotics, music production, invention and innovation to solve a genuine problem in our society or world. I remember not wanting to teach my students without providing these opportunities because I felt I was doing such a disservice to their futures. Why do we allow non-relevant learning to continue? When will students need derivatives in their lives? When will they need factoring on a daily basis? They shouldn't be forced to learn them unless they are part of the solution to the problems they are faced or challenged with.

This is what happens when we treat students and teachers as statistical data and numbers. If they aren't allowed to think for themselves and create relevant learning which addresses real-world problems, there isn't genuine challenge and application. I see many classrooms where content is 5-10 years old and is instantly disengaging because it's out of date. Why aren't more classrooms talking about and exploring our current political situation, possible trips to mars, renewable energy, how technology advances impact our society? I'm sure consciousness would be much stronger in these environments and half-heartedness would nearly disappear.

This is what my classroom looks like everyday, all day long. Students are in my art classes to produce, problem solve, learn from mistakes, learn from one another. They are actively engaged, the room gets messy. If an admin were to walk in, I'd hope they'd take a moment to observe and realize that what they are seeing is learning! Luckily I do have great admins so they do.

Learning with purpose! Where has this gone? Why is there no longer a greater purpose in most K-12 classrooms? It may have never been there to begin with but I believe if there is a purpose tied to social necessities, greater world good, solving cultural/global problems, many students would be more engaged and motivated to learn as well as rising stars.

Dewey spoke about this long before now and we still adhere to it, why is this? True innovations doesn't come from manuals nor does critical thinking and great problem solvers. Do we really still need manuals with the web and open source?

What kind of society is being formed now? Conformist or free thinkers? It seems we are headed in the wrong direction if we don't offer choice to teachers and students about their learning and growth.

The same could be said about standardized testing. Not that it's not important but it can't be the emphasis nor the entire focus.

Are we back in an age of educational individualism with our "personalized learning" etc? Should we be talking more about communal learning?

In terms of music space, I think of rehearsal, but rehearsal is made possible by the discipline of practice. They are same coin.

I live in the composition classroom both online and face-to-face. Are they rehearsal spaces? Yes. What other kinds of space can they be likened to?

Breaking out of ed tech hype.

It doesn't have to be just student feedback about the operations and mechanics of the course, or as a replacement for a course survey tool. You can also use the platform as a way to engage students on the content relevant to the learning outcomes of the course. And use the platform to connect learners with people in the field of study.

Key points:

1. Scale of data is especially good for large NNs
2. Having a combination of HPC and AI skills is important to have optimal impact (handle scale challenges and bigger/complex NN)
3. Most of the value right now comes from CNNS, FCs, RNNS. Unsupervised, GANs and others might be future but they are research topics right now.
4. E2E DL might be relevant for some cases in future like speech -> transcript, Image -> captioning, text -> image
5. Self driving cars might also move to E2E, but none of us have enough data image -> steer

Workflow:

1. Bias = Training error - Human error. Try Bigger model, run longer, New model architecture
2. Variance = Dev error - Train error. Try More data, Regularization, New model architecture.
3. Conflict between bias and variance is weaker in DL. We can have bigger model with more data.

More data:

1. Data synthesis/augmentation is becoming useful and popular: OCR (superpose alphabets on various images), Speech (Superpose various background noises), NLP(?) But does have drawbacks, if it is not representative
2. Unified data warehouse helps leverage data usage across company

Data set breakdown:

1. Dev and test should come from same distribution. As we spend a lot of time optimizing for Dev accuracy.

Progress plateaus above Human level performance:

• But there is theoretical optimal error rate (Bayes rate)

What to do when bias is high:

• Look at examples of the ones machine got it wrong
• Get labels from humans?
• Error analysis: Segment training - identify segments where training error is higher than human.
• Estimate bias/variance effect?

How do you define human level performance: Example: Error of a panel of experts

Size of data:

1. How do you define a NN as small vs medium vs large?
2. Is the reason large NN can leverage bigger data is because it would not cause overfitting unlike on smaller NNs?

The team on Google Translate has developed a neural network that can translate language pairs for which it has not been directly trained. "For example, if the neural network has been taught to translate between English and Japanese, and English and Korean, it can also translate between Japanese and Korean without first going through English."

A good blog post on why do you need to understand backpropagation links to videos from CS231n by karpathy.

In this Pearson sounds more like an edtech company than a content publisher. I wonder at what point will Pearson release a full LMS product that competes directly with BB, D2L, etc?

The tension in that last line on the cultural environments of technology vs academia is an important -and real-tension.

Hypothes.is nicely bridges the worlds of social media and formal education.

No representation of skill trees captures the concept completely, but what I hope is evident on this page is that any Badge, with its related Playlist, should be connected to other Badges and Playlists that come before (in this case, above) it, and it should be one of a few available choices (represented in this case by other Badges and Playlists on the same row), and that it leads to other Badges and Playlists (below it), and that what comes next has choices as well.

Wrong. If you just explained your skills to other people, like a textbook does, no one would understand, unless they have accumulated personal experience similar to yours -- which they would call, after the fact, "a circuitous route" to learning the textbook content.

Speech, writing, math notation, various kinds of graphs, and musical notation are all examples of cognitive technologies. They are tools that help us think, and they can become part of the way we think -- and change the way we think.

Computer interfaces can be cognitive technologies. To whatever degree an interface reflects a set of ideas or methods of working, mastering the interface provides mastery of those ideas or methods.

Experts often have ways of thinking that they rarely share with others, for various reasons. Sometimes they aren't fully aware of their thought processes. The thoughts may be difficult to convey in speech or print. The thoughts may seem sloppy compared to traditional formal explanations.

These thought processes often involve:

• minimal canonical examples - simple models
• heuristics for rapid reasoning about what might work

Nielsen considers turning such thought processes into (computer) interfaces. "Every theorem of mathematics, every significant result of science, is a challenge to our imagination as interface designers. Can we find ways of expressing these principles in an interface? What new objects and operations does a principle suggest?"

The technologies in learning the physics are:- To bring improvements in the students’ physics ability. To bring improvements in the negative reactions of students towards physics.

Every layer needs its own weights and bias. And in tensorflow, it is a good practice to put all weights inside a dictionary, which is easier for management.

I think any good course would do this. The deeper you look, the more there is to see.

Lifelong learning is essential for everyone, not just liberal arts grads. People in healthcare or engineering have to be able to adapt to changing times and technologies just like anyone else.

This work was in schools with teachers, right? When foundations and funders of after school programs ask about how to "spread and scale" the work, it baffles me that they don't begin to answer their questions by turning to how to effectively bring the innovative after school work to teachers and students in schools. Working on the connections between in school and out of school learning is important!
