Images processed 60K faster? No! And more…

28 January 2020 by Clark 4 Comments

Recently, I’ve run into the claim that images are processed 60K times faster than text. And, folks, it’s a myth. More over, it’s exemplary of bad practices in business. And so it’s worth pointing out what the situation is, why it’s happening, and why you should be on guard.

It’s easy to find the myth. Just search on “images processed 60K times faster than text”. You’ll get lots of citations, and a few debunkings. Most of the references are from marketing hype, selling you visual support.

The origin is suspicious. It’s always cited as coming from 3M, Polishing Your Presentation. Which is problematic, because when you go to that paper, you find the quote, but not a legitimate citation. Instead, there’s a vague statement about “findings from behavioral research” with no citation! Bad form.

A study done jointly between 3M and the University of Minnesota about presentations also is potentially a source. With only one small catch: it doesn’t mention 60K at all! Instead, it does conclude that “Presentations using visual aids were found to be 43% MORE PERSUASIVE than unaided presentations.” Which is hardly controversial.

Yet this is another zombie, like learning styles, that won’t die! It’s been researched by several folks, including Alan Levine and Jonathan Schwabish. No one seems to be able to identify a real piece of evidence. And it just doesn’t make sense!

In use, words are practiced enough to be recognized as a whole, serving as icons; they’re not repeatedly processed from letters into words. Second, images need parsing, too, and contextualization between the image and the current semantics.

Sure, we have many more neurons devoted to image processing than auditory, but that’s not only due to a sensory primacy (e.g. distance capability), but also the richness of the visual field. And more doesn’t equal ‘faster’. Yes, we’re processing in parallel, but nerve firing rates change based upon activation, not modality.

And this means that we have to have our ‘hype’ shields up. We need to evaluate any claims by several methods. Who else is saying this? Not pointing to the same (bad) data, but what convergent evidence is there? And what vested interest do the promoters have? And, importantly, does it make causal sense? Is there a plausible scenario when you dig beneath the surface features?

And, if you don’t want to read research published in the original academese, find those who you can trust. Those who’ve demonstrated a consistent ability to cut through the hype and the research, and bring good interpretations and debunk the myths. You can see my list of mythbusters here.

So, please, practice professionalism, avoid the hype, and use good principles in design and practice.

My Spring 2020 schedule and things I do

21 January 2020 by Clark Leave a Comment

My travels are a little more restrained this first half of the year, but then again, things change! And, it occurs to me to talk just a little bit about the things I do that aren’t speaking, writing, and consulting. So here’s my spring 2020 schedule and a bit more.

First, I’ll be speaking at ATD’s Techknowledge conference. I’m doing several things, including:

a talk on ‘transforming learning’ (a recurrent theme of late ;)
a talk on professionalism in practice (e.g. resisting myths)
potentially assisting another session
signing books

They’re doing things differently, and I laud their experimenting!

I’ll also be the opening keynote at the ATD New England annual conference on March 27. I’ll be talking the L&D Revolution.

There’s one more event coming June 15-16, in Belgium. I’ll be speaking at Mathias Vermeulen’s LearnTechDay, and running a workshop. Topics TBD, but I’m hoping it’s an LXD workshop and a Revolution talk. Games and mobile are, of course, also on the table.

That’s it, for now.

I briefly wanted to mention the other things I do, just so you have an idea of the weird influences that affect me.

I’m a CERT Plans Chief for my area of the city. Community Emergency Response Teams assist in dire events (wildfires, earthquakes, tornados, hurricanes, floods, etc) when first-responders (police, fire, EMTs) are overwhelmed. It’s valuable to me to know how to protect my family, friends, and neighborhood.

I’m a board member and treasurer (still asking myself how I agreed to that) for IBSTPI. The International Board for Standards in Training, Performance, & Instruction has been involved in creating competencies for different roles like Instructional Design, Instructor, etc. It’s in the process of a revitalization (stay tuned). I am in it to learn more about competencies.

I’m also on the board of eLearn Mag, an online journal of the Association for Computing Machinery (the society in computer science). The goal is to publish papers at the intersection of research and practice. This involves serving as associate editor for Emerging Technologies, reviewing papers, and soliciting some as well. If you’ve got a documented innovation, let me know and we can talk about getting it published. No PR!

I do serve as an occasionally reviewer for some other conferences and journals (e.g. Instructional Science and Education Technology Research & Development), to keep my knowledge up.

And I’m on the advisory board of a university ID program.

I also am serving on the committee of a Ph.D. student. I see my role as providing some real world balance (along with some academic knowledge).

When possible, I donate blood. My blood type’s O- CMV-, which means I’m the universal donor (and buggered if I ever need blood). I’ve donated gallons, and somehow it still doesn’t keep me thin!

All of the above is also about giving back. However, it means my philanthropic bandwidth is pretty much full ;).

There you have it, my intended peregrinations on my spring 2020 schedule (if you’re at one, say hi!), and a brief insight into how and why I spend my (few) extra cycles.

Signifying change

14 January 2020 by Clark Leave a Comment

I have a persistent interest in the potential for myth and ritual for learning. In the past I sought a synthesis of what’s known as good practice (as always ;) in an area I don’t have good resources in. When I looked over 10 years ago, there wasn’t much. That’s no longer the case. There is now quite a bit available about signifying change with ritual.

Myth, here, is not about mistaken beliefs, but instead are stories that tie us to our place in the universe. Every culture has had its origin story, and typically stories that explain the earth, the sky, and more. Ritual is a series of repeated behaviors that signify your belief in those stories. And when you look at prayer, and transition ceremonies, you see how powerful these behaviors are in shaping behavior. Can we leverage this power for learning?

Barbara Myerhoff opined that ritual worked because your body bought into it before your mind did. Thus, the repeated behaviors build a ‘muscle memory’ that supports your purpose. And agreeing to perform the ritual at all is an implicit complicity in the story behind the ritual. Finally, having others also performing or having performed the ritual builds a social commitment.

There’s clear power, but can we do it systematically? The sources at the bottom suggest we can. My synthesis says the answer is yes. There are two important distinctions. One is whether it’s individual or collective. Are we having a single person commit, or having a group commit? In the former, they may be becoming a member of the community, but it’s about changing personal behavior regardless. In the latter, it’s about someone becoming a member of a group of practitioners. (And, to be clear, here I’m talking secular change.)

The other distinction is the scope of the change. Is this a small personal change, or is this a switch to an entire system of belief? Are we helping someone be more productive, or asking them to buy into our organizational culture? If we want to transform people, signifying the change seems important.

Wwhat makes effective ritual is having a behavior that indicates allegiance to a system of belief. It’s essential that the behavior signifies the change in some way. It might be a part of the actions that the new desired change incorporate. So you mimic rolling out dough to cement your understanding of baking. Or it might be an iconic representation of some aspect of the belief, so drinking something specific as preparation.

The actual structure is suggested to be some initiating occurrence, like another instance (new client), or a particular time of day. Then there’s a process to be followed, typically with a preparation, a behavior, and a closing.

As usual, the process includes identifying the necessary elements, prototyping, testing, and iterating. Does it work with the audience, does it feel authentic, is it easy to do, are some of the questions to ask.

The materials I’ve found suggest ritual can be helpful. Two obvious roles are to successfully acknowledge their new status and/or sustain necessary mindsets and practices. When people have transformed, we want to acknowledge the change. And we want to help them continue to maintain and develop the new ability. Signifying change is an important component. We should be intentional about making that happen.

How do you drive yourself?

12 December 2019 by Clark 1 Comment

How do I drive myself? I was asked that in a coaching session. The question is asking how I keep learning. There are multiple answers, which I’ve probably talked about before, but I’ll reflect here. I think it’s important to regularly ask: “how do you drive yourself?”

As it’s the end of the year, my conversant was looking at professional development. It’s the time to ask for next year’s opportunities, and the individual was breaking out of our usual conversation to talk about this topic. And so he asked me what I did.

And my first response, which I’ve practiced consciously at least since grad school, is that I accept challenges. That is, I take on tasks that stretch me. (It might be that ‘sucker’ tattoo on my forehead, but note that my philanthropic bandwidth is pretty stretched. ;). This is professionally and personally.

That is, I look to find challenges that I think are within my reach, but not already my grasp. Or, to put it another way, in my Zone of Proximal Development. Accepting assignments or engagements where, with effort, I can succeed, but it’s not guaranteed.

Which means, of course, that there’s risk as well. Occasionally, I do screw up. Which I really really hate to do. Which is a driver for me to push out of my comfort zone and succeed. Or, at least, learn the lesson.

There’s more, of course. One thing I did started with my first Palm Pilot (the Palm III, the accompanying case is still my toiletry bag!). I had to justify to myself the expense, so I made sure that I really used it to success. This was part of the driver of the thinking that showed up in Designing mLearning, how to complement cognition. IA instead of AI, so to speak.

I also live the mantra “stay curious, my friends”. I’m still all too easily distracted by a new idea, but I don’t think that’s a bad thing. Well, as long as it’s balanced with executing against the challenges.

That’s how I drive myself. So, how do you drive yourself?

Passion and Learning

26 November 2019 by Clark Leave a Comment

My better half recently got a sample of special butter. A gift from a co-worker (an interesting story), and led me to reflect on the link between passion and learning.

M’lady’s co-worker is a fan of good butter. I was able to view a picture of her refrigerator, and the assortment of butters rivals what you might see in a fine grocery! We did a tasting between the ordinary butter we ordinarily purchase and this special butter. The difference was noticeable. I was reminded of the fine butter they serve when in Europe. Or at really fine restaurant.

This may seem odd, but think about it a bit. What do you care enough about to really understand? At various times I’ve been known to wax poetic about beer, cooking, waves, and more. And, of course, cognition, learning, engagement, and design. I managed to get educated about (American) football and cricket (yes, cricket) from inspired roommates. The list goes on.

And what’s fun is learning from these folks just why they find it so interesting. Which is related to the task of finding the intrinsic interest for designing learning. Talk to the experts! They’ve spent hours becoming experts, what motivated them? If you can find that, you’ve got a handle on it.

And I’m sure you’ve learned something from someone who was passionate about it. That’s usually a good indication that they’re also knowledgable, but there are caveats on that. People can get passionate about myths, too. There are reasons to be cautious. In general, however, you’re liable to be lucky.

Passionate people not only make fields comprehensible, they tend to drive fields forward. If you’re here, I’m expecting you’re passionate about performance & development. Maybe even up for a revolution! Let’s connect passion and learning to make it better.

Play to Learn

17 October 2019 by Clark Leave a Comment

Thinking more about Friston’s Free Energy Principle and the implications for learning design prompted me to think about play. What drives us to learn, and then how do we learn? And play is the first answer, but does it extend? Can we play to learn beyond the natural?

The premise behind the Free Energy principle is that organisms (at every level) learn to minimize the distance between our predictions and what actually occurs. And that’s useful, because we use our predictions to make decisions. And it’s useful if our decisions get better and better over time. To do that, we build models of the world.

Now, it’d be possible for us to just sit in a warm dark room, so our predictions are right, but we have drives and needs. Food, shelter, sex, are drives that can at least occasionally require effort. The postulate is that we’ll be driven to learn when the consequences of not learning are higher than the effort of learning.

At this level, animals play to learn things like how to hunt and interact. Parents can help as well. At a higher level than survival, however, can play still work? Can we learn things like finance, mathematics, and other human-made conceptions this way? It’d be nice to make a safe place to ‘play’, to experiment.

Raph Koster, in his A Theory Of Fun, tells us that computer games are fun just because they require learning. You need to explore, and learn new tricks to beat the next level. And computer games can be about surviving in made-up worlds.

The point I’m getting to is that the best learning should be play; low stakes exploration, tapping into the elements of engagement to make the experience compelling. You want a story about what your goal is, and a setting that makes that goal reasonable, and more.

To put it another way, learning should be play. Not trivial, but ‘hard fun’. If we’re not making it safe, and providing guided discovery to internalize the relationships they need, to build the models that will make better decisions, we’re not making learning as naturally aligned as it can be. So please, let your people play to learn. Design learning experiences, not just ‘instruction’.

Clear about the concept

19 September 2019 by Clark Leave a Comment

I went to hear a talk the other day. It was about competency-based education (CBE) for organizations. Ostensibly. And, while I’m now affiliated with IBSTPI, it’s not like I’m a competency expert. And maybe I expect too much, but I really hope for people to be clear about the concept. Alas, that’s not what I found.

So, it started out reasonably well, talking about how competencies are valuable. There were a number of points, and many made sense, although some were redundant. Maybe I missed some nuance? I try to be open-minded. It’s about creating clear definitions of performance, and aligning those with assessments. Thus, you’re working on very clear descriptions of what people should be doing.

It got interesting when the speaker decided to link CBE to Universal Design for Learning (UDL). And it’s a good program. UDL talks about using multiple representations to increase the likelihood for different learners to be able to comprehend and respond. This, in the talk, was mapped to three different segments: engaging the learners in multiple ways, communicating concepts in multiple ways, and allowing assessment in multiple ways. And this is good. For learning. Does it make sense for CBE?

To start, the argument was, you should make the rationale for the learning in multiple ways. While in general CBE inherently embodies meaningfulness in the nature of clear and needed skills, I don’t have a problem with this. I argue you should hook learners in emotionally and cognitively, and those can be separate activities. There was a brief mention of something like ‘learning styles’, but while now wary, I was ready to let it go.

However, the talk went on to make a case for multiple representations of content. And here the slide explicitly said ‘learning styles’ and used VARK. And don’t get me wrong, multiple representations and media are good, but not for learning styles! The current status is that there’s essentially no valid instrument to measure learning styles, and no evidence that even if you did, that it makes a difference. None. So, of course, I raised the issue. And we agreed that maybe not for learning styles, but multiple representations weren’t bad.

The final point was that there could be multiple forms of assessment. At this point, I wasn’t going to interrupt again, but at the end of the session raised the point that the critical element of CBE is aligning the assessment with the performance! You can’t have them do an interpretative dance about identifying fire hazards, for instance, you have to have them identify fire hazards! So, here the audience ultimately agreed that variability was acceptable as long as it measured the actual performance. Again, I don’t think the speaker was clear about the concept.

There were two major flaws in this talk. One was casually mashing up a couple of essentially incommensurate ideas. CBE and UDL aren’t natural partners. There can be overlapping concepts, but… The second, of course, is using a popular but fundamentally flawed myth about learning. If you’re going to claim authority, don’t depend on broken concepts.

To put it another way, I think it’s fair to expect speakers to be clear about the concept. (Either that, or maybe the lesson is that Clark shouldn’t be allowed to listen to normal speakers. ;) Please, please, know what you’re talking about before you talk about it. Is that too much to ask?

Sub-symbolic and Situated

13 August 2019 by Clark Leave a Comment

At the time that the connectionist folks were working on neural nets, another similar approach was genetic algorithms. Both were working in a different way than the previous formal approaches to AI. The distinction between the two became known as symbolic vs sub-symbolic. And it’s useful to review why, particularly in the current climate of increasing interest in AI and cognitive science. An interesting outcome is that the sub-symbolic work exposed the contextualized nature of our reasoning. So there’s a link between sub-symbolic and situated cognition.

The prevailing model, starting with the cognitive revolution which arguably began in 1956 (an auspicious year ;) was a formal logical one. Whether in ‘production’ rules of IF THEN, or other formal mechanisms, the notion was to operate on semantic objects like numbers and concepts. This reflected, at the time, the belief that we’re formal logical thinkers.

As cognitive research continued, there was a growing recognition that our behaviors didn’t match particularly well with formal logic (c.f. Kahnemann & Tversky’s work, summed up in Thinking Fast and Slow). Several cognitive scientists separately came up with structures that more aptly described some of the properties we saw: Roger Schank called them scripts (he was focused on episodic thinking, not semantic), Marvin Minksy called them frames, and Dave Rumelhart called them schemas (after Bartlett).

What Rumelhart subsequently saw was that the properties he was trying to capture were very hard to represent in formal logic. He went on, with his colleague Jay McLelland and their collaborators) to develop what they called Parallel Distributed Processing (PDP). These are now known as neural nets (NNs) and are the basis for much of machine learning.

I was in the lab at the time Dave and Jay were working on neural nets, but detoured down a different path. Following work on analogical reasoning (my Ph.D. thesis topic), I became aware of the work Holland, Holyoak, Nisbett, & Thagard were doing with induction. Their framework was genetic algorithms (GAs). Both GAs and NNs use input strings and output strings to work, but internally they represent things differently.

After so much work on symbolic reasoning, here were mechanisms operating beneath the symbolic level. Yet they were attempting to create symbolic behavior. NNs obviously, more closely resemble our cognitive architecture (though GAs are still used in some areas like program generation). So, our conscious thinking is symbolic, but our actual cognition is happening below our conscious thinking. Hence things like illusions, fallacies, myths, and more.

What emerged from this realization is that our cognition isn’t just sub-symbolic, but situated. That is, what is conscious is a combination of what comes in from our senses, and what we know. In fact, with the limited attention we have, much of what we think we’re perceiving, we’re actually generating!

This it accounts for why we’re bad at doing things by rote; we’re liable to confound steps and contexts. This ends up being important because it means we have to work harder for any learning interventions to work effectively across contexts. The relationship between sub-symbolic and situated is, at least to me, and interesting story of the development of cognitive science.

Yet, it still means that our learning works most effectively at the conscious level of symbols, because that can accelerate learning over having to deal with everything through practice and feedback. (And explains why programs talking about neural really aren’t working there.) We still need those, but conscious models can provide a framework to become self-improving over time. So don’t forget to provide the models, and sufficient practice, and feedback.

Lucky on Foundations

9 August 2019 by Clark Leave a Comment

I was thinking about my next directions, and it led to me to think a bit about my foundations. And I realized I’ve been very lucky (and I’m grateful). I’ve had good parents, mentors, colleagues, and friends. But I’ve also had some fortunate timings, and it’s worth reflecting how I’ve been lucky on foundations upon which to build. (A personal reflection, not necessarily worth your time ;)

It started with college, really. I’d always been a typical lad, but with an extra serving of geek (I didn’t fit in with any clique so hung with a few similarly chaotic-good chaps :). I started college interested in marine bio, but there was no formal link between undergrad study and Scripps. The bio program was all cut-throat med, and while I could cut it, it was all rote memorization and deadly boring. So…

I took some comp sci classes, and was tutoring for extra money on the side. Lucky chance: I got a job doing the computer support for the office that coordinated the tutoring. That sparked my awareness of the connections between computers and learning. Of course, back then, at my school, there was no such program. Luck 2: my school had a program where you could design your own major. I found a couple of professors doing a project on using email for classroom discussion (circa ’78; we had the DARPAnet, otherwise there was no email; more luck). They agreed to sponsor my project.

After graduating, I looked all over the country for an org that wanted someone interested in computers and learning. More luck, I finally came across Jim Schuyler, and as he was starting DesignWare, I got a job! And, importantly, it was designing and programming on the earliest personal computers. And I realized that there was real potential for learning in games! But I also realized that we didn’t know enough how to design them. And then I read about ‘cognitive engineering’ (applying what we know about cognition to the design of systems).

I was accepted into the cog program with Don Norman, who’d written the article. And this was another major stroke of luck. While Don’s students were researching how to build systems for how people think, my twist was about how people learn. I got to study behavioral, cognitive, social, even machine learning! Also, Don’s lab partner Dave Rumelhart was conducting his research with Jay McClleland on what became neural nets. You can’t help but get exposed to related research through lab meetings, seminars, and more, even if you’re not active in the particular work. And Ed Hutchins was doing his work on distributed cognition. This was a fundamental shift in perspective from formal to situated cognition.

The lab ran a Unix system, so I was getting steeped in computing systems to complement my personal computer work, along with the cognition focus. I subsequently did a post-doc at LRDC, getting deeper steeped into cognitive learning, and then joined a school of Computer Science, getting further background in computation. I was on the internet before there was a web (and foolishly was rather complacent about it)! And it’s enabled me to keep an eye on new developments like mobile and content and more, and understand their core affordance.

I also got steeped in design, having a chance to look at graphic, industrial, software, architecture, and other approaches (more luck). I combined that with a study of the academic literature, of course. These three foundations have been the basis of my work: applying cognitive and learning sciences to the design of technology to create learning and performance systems.

There’s much more to the story, of course. Serendipity continued in jobs and people to guide me, I’m happy to say. Mentors being shy, you can’t really thank folks enough, so if I’ve been lucky in foundations, it’s my job to pass it on. I hope that this blog helps in some way!
