Machine Learning :: Human Learning

AI - “artificial intelligence” - was introduced at a science conference at Dartmouth University in 1956. Back then it was a theory, but in the past few decade it has become something beyond theoretical. been less theory and more in practice than decades before.

The role of AI in education is still more theory than practice.

A goal in AI is to get machines to learn. I hesitate to say "think" but that is certainly a goal too. I am reading The Innovators: How a Group of Hackers, Geniuses, and Geeks Created the Digital Revolution currently and in that history there is a lot of discussion of the people trying to get machines to do more than just compute (calculate) but to learn from its experiences without requiring a human to program those changes. The classic example is the chess playing computer that gets better every time it wins or loses. Is that "learning?"

But has it had an impact on how you teach or how your students learn?

It may have been a mistake in the early days of AI and computers that we viewed the machine as being like the human brain. It is - and it isn't.

But neuroscientists are now finding that they can also discover more about human learning as a result of machine learning. An article on opencolleges.edu.au points to several interesting insights from the machine and human learning research that may play a role in AI in education.

One thing that became clear is that physical environment is something humans learn easier than machines. After a child has started walking or opened a few doors or drawers or climbed a few stairs, she learns how to do it. Show her a different door, drawer, or a spiral staircase and it doesn't make much of a difference. A robot equipped with some AI will have a much steeper learning curve to learn these simple things. It also has a poor sense of its "body." Just watch any videos online of humanoid robots trying to do those things and you'll see how difficult it is for a machine.


Then again, it takes a lot longer for humans to learn how to drive a car on a highway safely. And even when it is learned, our attention, or lack thereof, is a huge problem. AI in vehicles is learning how to drive fairly rapidly, and its attention is superior to human attention. Currently, it is still a fall back human error in mist cases, but that will certainly change in a decade or two. I learned to parallel park a car many years ago and I am still lousy at doing it. A car can do it better than me.

Although computers can do tasks they are programmed to do without any learning curve, for AI to work they need to learn by doing - much like humans. The article points out that AI systems that traced letters with robotic arms had an easier time recognizing diverse styles of handwriting and letters than visual-only systems. 

AI means a machine gets better at a task the more it does it, and it can also apply that learning to similar but not identical situations. You can program a computer to play notes and play a series of notes as a song, but getting it to compose real music requires AI.

Humans also learn from shared experiences. A lot of the learning in a classroom comes from interactions between the teacher and students and student to student. This makes me feel pretty confident in the continued need for teachers in the learning process.

One day, I am sure that machines will communicate with each other and learn from each other. This may be part of the reason that some tech and learning luminaries like Elon Musk have fears about AI

I would prefer my smart or autonomous vehicle to "talk" to other vehicles on the roads nearby and share information on traffic, obstructions and vehicles nearby with those quirky human drivers only.

AI built into learning systems, such as an online course, could guide the learning path and even anticipate problems and offer corrections to avoid them. Is that an AI "teacher" or the often-promoted "guide on the side?"

This year on the TV show Humans, one of the human couples goes for marriage counseling with a "synth" (robot). She may be a forerunner of a synth teacher.

The counselor (back to us) can read the husband's body language and knows he does not like talking to a synth marriage counselor.

 

What Is a Modern Learning Experience?

social on mobile

Jane Hart, who I have been following online for many years, is the Director of the Centre for Modern Workplace Learning, which she set up to help organizations and learning professionals modernize their approaches to workplace learning. Reading her online Modern Workplace Learning Magazine has alerted me to trends outside academia and outside the United States.  

She recently posted an article titled "Designing, delivering and managing modern learning experiences" and that made me consider how I would define "modern learning." It would include school experiences for some of us, but for most people today it is more likely an experience that occurs in the workplace and on our own. That itself seems like a big shift from the past. Or is it?

If in 1917, someone had wanted to become a journalist, he could go to college, but he could also get a job without a degree - if he could show he was a good writer. He could do some freelance writing with or without pay to get some experience and samples. Move 50 years to 1967, and the path was more likely to be a school of journalism. What about today?

As Jane points out, the modern learning experience path for the workplace probably includes using: 

  • Google and YouTube to solve their own learning and performance problems
  • social networks like Twitter and LinkedIn to build their own professional network (aka personal learning network)
  • messaging apps on their smartphones to connect with colleagues and groups
  • Twitter to participate in conference backchannels and live chats
  • participating in online courses (or MOOCs) on platforms like Coursera, edX and FutureLearn

The modern learning experience is on demand and continuous, not intermittent, and takes place in minutes rather than hours. It occurs on mobile devices more than on desktop computers.

Jane Hart believes it is also more social with more interacting with people, and that it is more of a personally-designed experience. I don't know if that is true for educational learning. Is it true for the workplace on this side of the pond? Does the individual design the learning rather than an experience designed by someone "in charge."

Modernizing classroom learning has often been about making learning more autonomous (self-directed, self-organized and self-managed) but that model does not easily fit into the model used for the past few hundred years in classrooms.

Defining Personalized Learning

mazeThe term "personalized learning" came up recently in several articles about Facebook founder and CEO Mark Zuckerberg and his pediatrician wife Priscilla Chan investing hundreds of millions of dollars a year in a new vision of “whole-child personalized learning.”

Their recently established Chan Zuckerberg Initiative (CZI) intends to support the development of software that might help teachers better recognize and respond to each student’s academic needs. But they also intend to use a holistic approach to nurturing children’s social, emotional, and physical development. That's a tall order. And not one that has not been attempted before.

In the 40 years I have been an educator, I have heard about personalized learning under terms like individualized instruction, personal learning environment, direct instruction differentiation and even adaptive learning. All refer to efforts to tailor education to meet the different needs of students.

The use of the term "personalized learning" dates back to at least the early 1960s, but definitions still vary and it is still an evolving term. In 2005, Dan Buckley defined two ends of the personalized learning spectrum: "personalization for the learner", in which the teacher tailors the learning, and "personalization by the learner", in which the learner develops skills to tailor his own learning. This spectrum was adopted by the (2006) Microsoft's Practical Guide to Envisioning and Transforming Education and has been updated by Microsoft in other publications.

CZI now has former Deputy U.S. Secretary of Education James H. Shelton as the initiative’s president of education. It is encouraging to me that he said “We’ve got to dispel this notion that personalized learning is just about technology. In fact, it is about understanding students, giving them agency, and letting them do work that is engaging and exciting... Many people have a preconceived notion that ‘personalized learning’ is a kid in the corner alone with a computer. Forget about that.”

CZI will direct 99 percent of their Facebook shares (an $45 billion) to causes related to education and science, through a combination of charitable giving and investment.

Being in technology, you would expect Zuckerberg to want to put a lot of the money and efforts into that area. That's what happened with many of the efforts that the Bill and Melinda Gates Foundation have made in education.

Adaptive learning - which I don't see as the same thing as personalized learning but some people do -  is an educational method which uses computers as interactive teaching devices. The technology allocates both the human (teachers, tutors, counselors)  and mediated resources according to the unique needs of each learner. Computers adapt the presentation of educational material according to students' learning needs. A lot of computer-aided assessment and responses to questions, tasks and experiences direct the next step for the learner.

Adaptive learning technology encompasses aspects derived from various fields of study including computer science, education, psychology, and brain science. Although this approach is not teacher- or student-centered, it does attempt to transform the learner from passive receptor of information to collaborator in the educational process. Adaptive learning systems have been used in education and also in business training. 

CZI realize this personalized learning will extend over decades. They began in December 2015, shortly after the birth of their first child.

The Initiative has invested in BYJU’S, an India-based startup behind a popular online-learning app, and Enlearn, a Seattle-based nonprofit that has developed a new adaptive-learning platform. CZI has also partnered with the Bill & Melinda Gates Foundation on a $12 million “venture philanthropy” grant award. 

When I was starting my teaching career in the mid-1970s, the personalization was mostly driven by teachers and rarely used technology. 

But how does this fit into the newest version of the main federal K-12 education law, Every Student Succeeds Act. Unfortunately, our national plans usually only last for only 4 or 8 years (based on administrations), so we never see a cohort of students go through an educational lifetime. The new law does seem to push states and schools to think about more than standardized-test scores when determining what it means to help students thrive.

Do we need a clear and set definition of personalized learning in order to move forward? How does the CZI idea of educating the "whole child" fit into personalizing learning? 

How Disrupted Is Education?

track disruption

I had bookmarked a post last fall on emergingedtech.com about digital disruption and it got me wondering about just how disruptive some recent "disruptors" have actually been to education. The article lists six: Delivery, Flipped Classroom, Tools Available, Micro-credentialing, Competency-Based Education (CBE) and Learning Science.

You can argue with their six choices, but they are all disruptors. I might have added others, such as Open Education Resources, including MOOC, but I suppose that might fall under "delivery" too. 

In 2012, when I was deep into MOOCland, I read The Innovative University: Changing the DNA of Higher Education from the Inside OutIt is co-written by Clayton Christensen, who is considered "the father of the theory of disruptive innovation." His previous books include The Innovator's Dilemma, which examined business innovation, and The Innovator's DNA: Mastering the Five Skills of Disruptive Innovators

After four decades as an educator, I would say that education in general gets disrupted rather slowly, but here are some thoughts on these disruptions. Are we talking about disruption in K-12 or higher education, or in the whole of educations.

By DELIVERY, they are including, and probably focused on, online delivery. The US DOE reported back in 2012 that 1 in 4 students has taken some or all of their courses online, and that figure is predicted to grow steadily. In higher ed, online learning is firmly in place. It disrupted, and now the waters have calmed. In K-12, the disruption is still to come.

The FLIPPED CLASSROOM was big a few years ago in K-12. It never really caught on or was part of the conversation in higher ed. It's not gone and it is still being tweaked and studied. This idea of  on continues to expand. The annual Horizons Report for 2015 predicted this would have widespread adoption immediately, but that didn't happen.

Certainly the number and VARIETY OF TOOLS available to educators has grown and continues to grow every week. Viewed as an umbrella of tools, they are more disruptive than any individual tool. We have seen many predictions that adaptive learning tools, VR and AR, 3D printing and other tools would radically change they way we teach. None of them have "changed everything."

Maybe you're seeing a pattern in my responses. There hasn't been a major disruption. When I wondered four years ago who was really being disrupted in higher ed, I was thinking about what a University 2.0 might mean. I have the larger category on this blog of Education 2.0. We definitely moved into Web 2.0 after only a few decades, but after a few centuries education is beyond 1.0 but not over the line into a major change that I would consider 2.0. 

I do believe that things like MICRO-CREDENTIALING, CBE and the growth of LEARNING SCIENCE will change things. Combined, all these disruptors will certainly move us closer to that Education 2.0.

Beyond micro-credentialing, I see an entire reconsideration of credits and degrees as the biggest disruption to traditional education (as opposed to learning). Will movements like the Lumina Foundation's framework for “connecting diverse credentials” unite (or divide) non-traditional sources like MOOC courses and professional development training?

That leads right into Competency Based Education. The Department of Education (which plays a much bigger role in K-12) seems to be very serious about CBE.  This is big disruption of the centuries old clock hours and seat time for credits towards degrees. 

LEARNING SCIENCE that is deepening what we know about how we learn, and the relationship between different tools, may have a bigger impact on pedagogy than on how a school looks when you walk into a classroom. 

Maybe the Internet or "technology" should be the disruptor we point to that changed education as it touches all of these other disruptors. 

Want to Launch an Online Courses Business?

online learningHaving spent so many years in education, the idea of trying to launch an online courses business  has never really been on my mind. What would you need to start an online courses business?
I would assume that almost all your concerns and needs would parallel the ones we have in education. It came to mind when I saw a post meant for someone who did want to "Launch a Successful Online Courses Business and offers podcast episodes collected about some of those concerns.
In academia, we strive to attract students. A business model would want to attract clients. But most concerns are similar. For example, you would need to create or choose a learning management system. You would need to explore all the online pedagogy that has emerged the past digital decades. For example, online educators have moved towards shorter courses using 
smaller units. One of the podcasts is on Ways You Can Shorten Your Course which includes “chunking.” Chunking means dividing information into small pieces and grouping them together so they can be stored and processed more easily by learners. That is the kind of design and pedagogy that has come from studying how online learners process information. The way the brain observes and processes information is limited by our working memory's limited ability to process large amounts of data at the same time.
Having spent twenty years launching online courses in higher education, I don't envy anyone starting an online business, but you can certainly build on the work that has been done and have an easier time of it.

Why Create and Use Open Educational Resources?

open textbooksI'm currently working on redesigning courses to use only Open Educational Resources (OER). Ever since I have worked in higher ed, whenever I have discussed open resources that are offered for free some faculty will always ask "Why do people create these things for no money?"
Most of us do our work and create our "intellectual property" (some of which is called that isn't really IP) in order to make money, and in academia to gain promotion and tenure too.
Some of the main motivations for creating OER are the same as the reasons for using OER. In my current project at a community college, we are trying to create course that save students money. Ideally, the course has no cost after students pay their tuition. The biggest cost is almost always textbooks, so using free, open textbooks is important.
I feel that too much course design is based on the textbook used, so OER redesign offers an opportunity for real course redesign. 
On the pedagogical side, open textbooks solve the problem of students simply not buying the book and trying to get by without it. I taught in secondary school for years and all the textbooks were free and I will always say that a free book does not solve the problem of students who do not read the books.
We also know through many studies that students who are strapped for money often choose courses when possible based on low or no cost for textbooks.
Students get annoyed when a professor only uses a small part of the textbook. Using open textbooks allows us to select the sections that we really want to use. Many OER courses use portions of several texts - a few chapters from one and a few from another.
If you not totally happy with the content in an truly open textbook, you can edit it yourself. You can add your own content, add your own images. Of course, in most cases those edits also have to be made open to others to use. I think of an open textbook as a starting point.
Which brings us to the point that creating an OER course takes work. Finding resources is very time-consuming. Editing them is work. If you do it, you do it for your students, for education and for a love of learning that you want to share with the world.
OER creators don't usually make money from their efforts, although there are platforms that offer resources in printed formats for a price. But creators can get recognition and exposure for their efforts and that can sometimes help in the job-hunting and promotion and tenure processes.
