Are humans “biological learning machines”?

[631 words]

The other day, I blurted out that human beings are “biological learning machines.”

I would like to take a step back and think about this a bit more. I realize now that a significant part of the impetus behind my words were readings that I had been doing about human evolution and the fact that homo sapiens seems to have developed a very particular cognitive profile. One book in particular, Yuval Noah Harari’s Sapiens: A Brief History of Humankind (2015) points toward what he calls a “cognitive revolution” which he suggests was one of the most important developments in the history of our species that took place approximately 70,000 years ago. For Harari, this “revolution” was the result of changes in the hominid brain that allowed the development of contrary-to-fact thinking, vast imagination, and complex conceptualizations expressed through language. These capacities undergirded the emergence of generalized human culture, of myths, of ideologies, of concrete and abstract representations (and misrepresentations), of large-scale social organization and cooperation. Those evolved aspects of the human brain are responsible for our being able to think about the past and the future as well as the present, and being able to plan, to imagine alternatives and to critique and analyze. They make possible the development of writing, record-keeping, archiving and inter-generational learning. I note that Yuval attributes a somewhat lesser role to memory than I think the word “learning” evokes, although he does note that it is homo sapiens’ ability to retain and recall a large amount of relevant information that allows individuals to operate effectively in complex social systems. Still, individual, collective and archived memories are an important part of my own broad view of learning, as are communication networks and shared understandings.

What I believe and what I was trying to say in my blurted declaration about “what human beings are” is that all of these characteristics make us high-capacity, highly adaptable, highly effective learners. Indeed, that complex fact may be the principal evolutionary advantage of homo sapiens. We are learning machines. We learn from experience; we learn through abstract conceptualization and theorization; we learn through experimentation; and we employ intense cognitive processing to make our learning memorable and durable. Add writing, archiving and mutually negotiated standards to the mix and it is clear that we humans constitute a living, global, rhizomatic network of learners and repositories of learning. It is clear that we are programmed for learning and knowledge development, much in the way that viruses are programmed to take over protein production in targeted living cells, to produce additional viruses.

Learning is, perhaps, what humans do best and it is the thing that our evolutionary heritage impels us, indeed, compels us to do. By “learning,” I obviously do not mean simply memorizing information in order to pass a test. I mean it in the largest sense of developing new knowledge, new insights, and new understandings that we share broadly in a way that informs the knowledge, insights and understandings of others, assuring both a measure of homeostasis and change across a social-cognitive network of education and scholarship. We humans have an astounding talent for generating, refining, improving, and interconnecting meaningful ideas. We produce systems of concepts, formulae and metaphors that model the universe and that make our understandings communicable. This high capacity for learning, both individually and collectively, has made us into a kind of creature somewhat beyond all other evolved beings on this planet. So, while there are many ways to characterize what we have become as a species (neurotic and domineering animals, the ultimate apex predator, featherless bipeds, agents of planet-wide destruction, self-obsessed and hubristic creatures, the talking animal, the writing animal, the self-identified “highest form of consciousness”), it is clear to me that my improvised bon mot the other day was absolutely on-target. Beyond that observation, I would point out that my formulation has significant implications for the future of education.

Humans are indeed biological learning machines, an idea that I’ll explore further in later posts.

My expectations of this MOOC, my view of the future of education

[1018 words]

(week 1 journal for the “What future for education?” MOOC)

First, here is the prompt from the MOOC (“What future for education?“):

Week 1 Journal Entry: Based on your experience as a learner, what do you think you will be able to get out of this course? And what ideas do you already have about the future of education?

As I think I made clear recently in my initial blog post, I believe in the value of dynamic, learner-centered, self-motivated and autonomous learning that employs dialogue and collaboration to extend and refine individual investigation and reflection. I value “learning for the sake of learning” — that is, engaging in discovery and idea formation because the content one is focusing on and/or the process of learning are fun. In my own life, that kind of learning looms much larger and has deeper resonance than learning for extrinsic motivations. To put it another way, the best learning (in my view) is self-motivated, driven by the learner’s curiosity, interest, and sense that the learning content/activity/context has relevance and meaning. In my case, learning for purely extrinsic rewards (grades, diplomas, certifications, financial rewards, reputation, advancement) is significantly less effective and far less enduring. Given my overarching attitude toward learning, I would say that this MOOC will offer me a lot.

Let me explain. I am interested in the future of education. I am very interested in learning theory. I believe that these topics are highly relevant for me — and, indeed, are relevant for any curious and thoughtful person working in higher education. In other words, my motivation for engaging with the themes of this MOOC is quite high.

To that, I would add that the specific questions asked and the seemingly connectivist modalities of this MOOC are likely to work very well for me, particularly if I am able to find a few student peers whose interests and enthusiasms resonate in some way with my own, folks with whom I can engage in productive dialogue and debate. I suspect that I’m likely to encounter others who, like me, draw a sharp distinction between learning and education and who would be willing to explore the complex relationship between the two. I hope that I’ll be able to have some lively exchanges about cognitive-sciences-informed learning as a driver of education in the future and perhaps even consider ways in which the enterprise of higher education, indeed, education in general, might be rethought to facilitate, guide and support learning, whether individual or collective, in a more effective and sustainable way.

As I think about the future of education, I am convinced that many stakeholders in the educational enterprise will need to rethink the basics of what they are doing. Why educate? To what end(s)? What does society need educational systems to do? Is education exclusively about creating competent workers? Is it exclusively about “learning for doing,” so to speak, or manufacturing, or performing needed services, etc.? Is it about “learning to be”?  Ought universities teach students to be lifelong autonomous learners? Should universities teach students to seek wisdom? Or help them learn how to balance their lives? Or exercise self-control? Or engage in deep reflection for spiritual and intellectual growth? Is it about filling brains with information?

To evoke another dimension… technology is potentially both a complicating factor and a highly effective pathway as we think about the future of education. That is, computer-mediated communication and digital tools do not constitute a solution per se. Indeed, blind or unthinking appeals to technology or imposing the use of specific apps or devices without good support or good justification are, as pedagogical choices, likely to create more problems than they solve. On the other hand, if education is understood as a process of supporting, connecting and guiding autonomous learners, then computer-mediated and digital communication, collaboration and information-sharing can potentially be affirmed as valid and valuable infrastructures and/or pathways of learning and education, if not an obligatory route. Where and how technology plays a role depends on the needs of learners, the context in which learning takes place, societal parameters, the quality of the match between the technology itself and the desired cognitive results and learning outcomes, and another multitude of factors.

To do a better job of facilitating learning and creating better experiences for learners, we need to increase our understanding of the cognitive processes involved and we need to assure that educational processes, educational pathways, educational tools and teaching strategies align with how learning actually works in the human brain. We need to be clearer and more explicit about the goal(s) of education. We need to employ approaches that support those goals. Let us ask questions of the educational enterprise at all levels. Is the main goal of primary or secondary or post-secondary education the socialization of human beings into into learning communities? Is education about the acquisition of skills and socialization into professional practices? Is it about teaching individuals to assume greater autonomy for their own educational achievement and greater effectiveness in living satisfying and ethical lives? Those are three very different kinds of learning that might properly belong to different levels or different types of education. What about continuing education “on the job” (i.e. job training, continuing vocational training). Should employee education  be limited to teaching workers to work more effectively or conform to employers’ procedures? Or might mindfulness, critical thinking, the scientific method, financial literacy and various other “life skills” also properly make up the education in the workplace? We talk about life-long learning, but what do we do to actually structure and implement extremely effective modes of learning throughout the life cycle of citizens in our various societies?

I do not have answers to those questions, although I have some intuitions about how we ought to think about them. At this point in my journey through this MOOC (a “preview” of week 1), I have begun formulating what I believe are pertinent questions about the future of education and I am pondering the relationship between “learning” and “education.” In my view, those results alone signal real promise as I begin to engage with this MOOC.

Learning, from my perspective

[2351 words]

I will say from the outset that I am launching this blog in part as an exercise for a Coursera course, “What Future for Education?” The course is offered by the University of London, specifically the UCL Institute of Education. Obviously, it is designed and managed by a number of folks. The named teaching professor is Dr. Clare Brooks. The MOOC seems to be broadly connectivist in orientation since it asks participants to reflect on aspects of education and learning, to post their reflections, then to engage in dialogue and further reflection, to learn from the experience of dialogue, debate and exchange.  I am using this blog, at least initially, as the site of my reflections for this MOOC. I must admit that I have another signifiant motivation, since I am interested in publishing a book about the future of higher education in the United States and about learning in general, including investigations about why one would choose a traditional undergraduate education and what the alternatives could be. All of the foregoing might help guide American universities, including my own, as they think strategically about future developments. However, it is mostly to satisfy myself that I am doing these things (pursuing MOOCs, reflecting on learning and education, planning a book on that subject).

So let’s proceed now to the ostensible initial impetus for this blog , the “What Future for Education?” MOOC. Here is the initial reflection prompt for the first major unit in the course:

Reflect on:
  • your previous learning experiences. Think about one particularly successful and one unsuccessful learning experience. Consider what were the conditions that made this experience successful or unsuccessful for you and what this tells you about your own preferred ways to learn.

The following paragraphs are my reflections on successful and unsuccessful experiences in learning. (Note that I draw a sharp distinction between education and learning, even though many folks believe that they are practically synonymous.)

Less successful.

To illustrate a lack of successful learning, I would probably point to a philosophy class that I took at a private liberal arts college, where the professor lectured a great deal. In his talks, he usually restated the content of assigned readings from a highly structured textbook. He gave us writing assignments and tests based on readings and on his lectures. Those lectures and those writing activities were, in my view, counterproductive. They did not encourage students to make new connections or explore the subject matter beyond the book. Nor did they encourage learners to develop and test their own ideas. All essays and in-class exercises were patterned very closely on the textbook. The professor seemed to grade student work according to how closely it followed the arguments and ideas as presented in the textbook. The students who got the best grades were the ones who parroted the professor and followed the textbook most closely. In short, it was a course where the teacher saw his role as that of supervising students’ making their way through the textbook, regurgitating what they had read and heard, showing some understanding, but not really extending beyond the terrain delimited by the readings. The subject matter and style of the course were pre-determined by the textbook format and content. The teacher added relatively little to it, and students were actively discouraged from showing significant initiative, intellectual curiosity or deep cognitive processing. Most of all, we were discouraged from challenging the authority of the textbook or of the professor. We were expected to absorb, memorize and faithfully reproduce the ideas and information as they had been packaged in the textbook and reiterated by the teacher. My summary judgment? It was perhaps the worst philosophy course I have ever taken and, to be honest, I remember very little of the principles or ideas we covered in the class. I earned a passing grade, but I disliked the class because it failed (in spectacular fashion!) to excite my passion or stimulate my curiosity. Indeed, it killed curiosity, wonder and a desire to explore. It did gave me little to do other than memorize formulations. At the time, I thought of it as “boring.” What I now realize is that is was not engaging, that it did not challenge me or force me to work through ideas or do intensive cognitive processing. I was not challenged to wrestle with the major ideas. The professor did little to encourage me to integrate the concepts of the course into my previous learning. I did not make any significant new connections and I certainly did not commit course concepts to long-term memory. I read, listened, memorized (for the short term), then I regurgitated formulaic expressions. My unenthusiastic work in the course had its prime mover in extrinsic motivations. (It was a required course that I needed to earn my diploma.) I had little in the way of intrinsic motivation and the professor’s manner certainly did not kindle the flame of my desire to learn. On the contrary, he extinguished it in this course. I did not see the relevance or the purpose of the course. I thought the whole affair was a waste of my time. All things considered, that course was a terrible and, in my view, unsuccessful, learning experience, even though I earned an “above-average” grade.

More successful.

MOOCS. I have taken a variety of MOOCs which, despite my best intentions, I’ve had trouble completing. When it was feasible (which is to say, when I did not have an excess of interruptions or crises to deal with), I completed all assignments in these courses, sometimes earning a certificate, sometimes merely auditing. In general, I would consider the vast majority of those experiences highly successful learning events, even in cases where I did not finish the course. Failure to complete the course was usually due to the fact that I was pursuing that learning experience at the same time as I was teaching a full load, serving as Chair of my academic department and doing other administrative work. Often, difficulties or crises erupted in my teaching or in my administrative tasks that were so large or so problematic that they interfered with my learning, even “after hours” and at home. Indeed some emerging problems emerged that took up so much of my time that I was forced to set the MOOC aside entirely, missing deadlines or abandoning assignments that I had begun but not completed. Yet even in those cases, I often had a positive, effective and highly meaningful learning experience.

One such MOOC was “The Ethics of Eating,” offer by Cornell University in 2014. It is a course for which I did not earn a passing grade because I abandoned it at about the mid-point (out of necessity rather than by choice). I had found it highly engaging. Indeed, I retained a lot of the ideas, principles, notions, etc. that were covered in the course. Much of the thinking and the cognitive processing I did in that MOOC continue to inform my thinking about ethics and food (and the relationship between humanity and the natural world). Until a significant problem emerged in my department, forcing me to go inactive in the MOOC, I was completing all of the required work and I felt stimulated to think further. I was extremely active on the discussion board. I found and commented on many  connections both with my personal life and with previous learning (ethics, history, nutrition and health, gastronomic culture, familiarity with farming, animal husbandry and animal slaughter). Even though I did not earn a passing grade, the learning that I did in the course stuck with me. Indeed, it continues to resonate in my thinking and in my intellectual life. It informs my moral choices and it informs my teaching. It provokes further reflection and presses me to continue struggling with the complex and difficult issues of food production, food consumption and human domination of animals and of the natural world.

Conclusions? Implications?

What is it about the face-to-face philosophy course (which I passed) that makes me think that it was unsuccessful, whereas I consider a MOOC that I “failed” to be a great and resonant learning success? Engagement. Relevance. Autonomy. Struggle. Interest.

The face-to-face class “under-stimulated” me whereas the online learning experience was very challenging. The MOOC was not excessively difficult, but it certainly exposed students to a wide and complex range of ideas, data, opinions and presentation styles that required a lot of work to understand and integrate. The expectations in the MOOC were clear, setting a high bar, while also providing plenty of scaffolding, reflection prompts and tools. It was a well-planned and dynamic course. That experience offers a significant contrast to my face-to-face philosophy course, which seemed very staid, static, and lacking in real challenge. In the face-to-face course, there was no real dialogue between the students and the professor or between the students and the content of the course. In the MOOC, on the other hand, there was an immense amount of dialogue, conversation and confrontation between divergent points of view. 

So, I would say that for me as a learner, I need a large measure of challenge, high expectations, clear standards, interesting complexity and opportunities to engage further. Those elements spell out one formula for successful learning in my view. Learning happens when the course or module allows me to work autonomously, making connections with my own current or previous experience, while also engaging in dialogue with others. A good learning experience is one that challenges me. It provides me with good materials to explore and learn from. Such a course or learning experience will ask me interesting questions. It will offer me a challenge, then let me work. It will provide me with a bit of structure, with clear standards and expectations, appropriate tools and someone open-ended opportunities. When those things happen, I learn enthusiastically.

If you want me to engage in exuberant, meaningful, durable learning, please do not dictate to me or tell me what to think. Don’t force me to fit a pre-determined mould. Don’t reiterate what is in the book. Don’t restrict my expression. Don’t claim teacherly authority based on, well, nothing except an academic title and years of experience. If you want me — or others — to engage with the intended learning content, encourage the development of new ideas, new connections, new formulations. Do facilitate critical engagement. Do promote and encourage competence and innovation. Do help students to see the relevance of the material. Do make the most important principles of curriculum design apparent.  Do make the gist of the course relevant and compelling. Do allow a variety of genres and modalities of thought and expression. Do encourage and value creativity.

In short, for me, learning happens best when it is largely self-directed and when I have a high degree of intrinsic motivation, based on my understanding of the relevance of the activity, material or course. It works best when there are well-structured steps or stages or interconnecting components that are aligned in a process that allows me to set my own pace and do as much or as little as I want, but that also leaves many things open-ended for exploration and additional meaning-making. Learning works when I have the opportunity to wrestle with ideas and information, and when the work of the course encourages me to articulate for myself important connections between the new learning and previous learning, or to articulate implications or consequences of the new ideas or that facilitates my doing so in dialogue with others. It works best when I have some scaffolding, but when the learning experience is not inflexible or excessively determined. It seems that I learn best by doing my own investigations and reflections and by committing my cognitive processes and conclusions to writing, often in collaboration with others as part of the process.

I recognize that there are learners who are very different from me, who want a highly structured course with strict timelines and restricted or extremely-well-defined activities, who hate to be left to figure out how much to write or what to write about. For some folks, the philosophy course that left me very disappointed would be terrific. For those same learners, a MOOC that gives them “only so much” structure, then leaves them to figure out on their own or in collaboration with other learners just how much to write and what to write or exactly how to understand or use the proposed curricular materials (readings and videos)….  That experience might be nothing more than an anxiety-producing mass of indeterminacy for them. Indeed, if someone is more concerned about earning a grade for a certification or taking a specific step toward a diploma, but when they are not interested in the content of the course, they might hate the MOOC that I found so engaging and so meaningful. In short, one’s preferences and one’s attitude toward learning are important factors in the learning experience. Still, I think that there is a great deal in higher education in the United States that needs to be reconsidered, to make it friendlier and more effective for “distributed” learners like me.

PS – to be fair, I note that the philosophy class that I valued so little took place nearly three decades ago, whereas the MOOC I cited dates from only two years ago. That said, the effect of the former on me at the time I took it was significantly less powerful than the effect that the latter had on me two years ago. It may be that I was a higher-quality and better-prepared student with a lot more cognitive resources in the case of the latter, since I took the MOOC in my 23rd year of tenure-track teaching, than when I took the philosophy class as a wet-behind-the-ears undergraduate student. Still… one course was highly meaningful. The other was far less so. I would gladly re-take one of them, but not the other. In my mind, even as I try to maintain a reasonable and balanced perspective, there is a world of difference between the two instances.
