Squaring the Circle: The Learning Analytics Dilemma

(Originally Published on nmc.org May 2012)

Learning analytics presents some serious dilemmas for the academic community. It is tempting to think that our advancing capabilities in data collection and processing make understanding the learning process an achievable goal. However, because we have never really managed to define what successful learning looks like, figuring out what and how to measure, much less how to use that data to change what we do, poses some major challenges. My experience teaching this semester as well my intellectual effort in imagining a learning analytics platform have shown me that there are at least three major, interconnected hurdles to overcome before we can proceed: definition, doctrine, and culture.

Before we can go into the technicalities of developing a learning analytics system, we need to come to some definitional agreement over the ultimate purpose of higher education. Is it to teach a basic canon of knowledge? Is it to teach critical thinking skills? Or, is critical thinking not going far enough? Do we need to teach what Michael Wesch calls “knowledge-ability?”

Our only hope of developing meaningful variables to measure learning is by clearly defining our educational goals. Making meaningful comparisons across multiple classes, and even more so across disciplines, depends on coming to some sort of consensus around these often-divisive issues.

In addition to being clear about definitions we also need to address the doctrinal dichotomy over whether learning is essentially a cognitive process or behavioral process. A behaviorist would argue that learning could, in theory, be broken down into a set of discrete steps or benchmarks that lead to success. This approach would lend itself quite well to the quantitative aspects that big data would seem to offer us. Its misuse is also, unfortunately, the basis for much of the standardized testing environment that we have seen inflicted on the K-12 environment.

There is a powerful cognitive counter-argument, recently expressed by Gardner Campbell in addressing George Siemens’ LAK12 MOOC. The argument here is that learning is essentially impossible to quantify because it is a voyage of discovery with ill-defined markers along the way. The job of a teacher is to facilitate this voyage among his or her students. How do you measure the learning process using this approach? Can we develop a tool to measure curiosity, for instance? Furthermore, quantification risks taking education even further over to the dark side of standardized formulas for “learning.”

Philosophically, I wholeheartedly agree with Gardner’s position on this subject. I spent most of graduate school arguing for a cognitive model in international relations and it certainly appeals to my right-brained nature. Furthermore, I know my own learning process has been governed to a large extent by my insatiable curiosity. At the same time, that curiosity attracts me to the possibility of dissecting the learning process in a meaningful way. This is also in part because I continue to be frustrated as a teacher in trying to understand my inability to motivate the vast majority of my students to undertake curiosity-generated, self-directed learning.

Even if we can get past the definitional and cognitive/behaviorist issue, there is yet a third hurdle and that is cultural/institutional inertia. My recently concluded semester teaching a government class is a good example of the perils of getting too far ahead of the curve or outside the norms of traditional teaching approaches. As usual, I started the semester with high hopes that trying something new would lead to greater success for my students. I refocused the syllabus around a skills-based approach and attempted to give my students the freedom to explore areas of interest to them. I also tried some novel technological solutions such as incorporating Google+ and Google Docs into the workflow with the goal being to mentally take students out of the classroom as much as possible. At the same time I wanted to give them exposure to technical tools that they will need master in future work environments.

This experience left me disillusioned over my ability to break through cultural norms even in my own class, much less convincing other faculty to attempt similar efforts in their own classes. From the perspective of a faculty member, breaking down my assignments into their skill components was hard work. As a teacher with a built-in motivation (my interest in learning analytics) and an unusual propensity to take risks in class, I was able to convince myself to see this through. My experience with other faculty is that they are often understandably risk-averse and resistant to change. In other words, I’m not sure what I attempted was scalable even if it could be proven effective.

Furthermore, the changes required a significant paradigm shift on the part of both my students and myself. The students resisted, for the most part without complaint or feedback, my attempt to shift the paradigm of their learning experience. I ultimately gave up on trying to impress the significance of this approach on them. For the most part they were only concerned with the bottom line of what their final grade would be. Furthermore, freedom to explore did not agree with many of them as the class had a high failure rate. This was because many of them used their freedom to avoid doing the minimum amount of work necessary for success in the class.

The bottom line is that both students and faculty will resist this kind of cultural shift. It’s hard work and it involves an intellectual paradigm shift many won’t be willing to undertake. It’s hard to imagine a meaningful learning analytics project without a significant re-evaluation of teaching and learning being a part of the process.

To reinforce the point, I recently attended an iPad workshop put on by Apple. In it, they demonstrated how the new iBooks app, coupled with iBooks Author, could be used to create self-tests and flashcards for the readings. When I pointed out to the presenter that this was a classic McLuhanesque mistake and, furthermore perpetuated an outmoded form of teaching (rote memorization), he pointed out to me that, while he agreed with me, this was what most of the audience wanted to see pitched. Unfortunately, I could not argue with him on that point.

I am down but not out when it comes to learning analytics and the related mission of reinventing teaching and learning to meet the realities of the modern world. While I don’t see it as a magic bullet for student success, I continue to hope that it will provide critical insights to enable us to find a pathway to achieving those ideals. It also offers me an irresistible intellectual puzzle with the hope of making a real difference in the lives of our students.

As Yeats said, “Education is not the filling of a pail, but the lighting of a fire.” We clearly need more matches and less water. At the same time we can’t overlook the theoretical, doctrinal, and cultural barriers that will impede meaningful measurement of the learning process, much less allow us to reshape the process based on the data produced. However, we ignore the coming seismic shifts in teaching and learning at our peril. There is still a lot of discussion and hard thinking to be done here. In order to square this circle we have to figure out how to be disruptors while preserving the essence of what makes education such a special experience.

The Visualization Gap

(Originally Published on nmc.org in August 2015)

I was recently reading Bryan Alexander’s excellent post about making effective use of PowerPoint. This got me thinking about the much bigger challenge lurking out there, of which bad presentations are only the tip of the iceberg: Visualization Literacy. This theme has concerned me for some years now. Indeed, arguably it spans the 30 years of my photographic experience, as photography is a struggle to achieve a particular form of visual storytelling. I have given photography presentations in which I discuss photographic composition as a form of visual narrative. There are also many issues that overlap with my yearlong discussion of technology design, which relates to my struggles to both teach and master visual literacy myself.

My presentation on narrative photography on Slideshare

Calling on one of my favorite quotes, Marshall McLuhan said in The Medium is the Message, “The serious artist is the only person able to encounter technology with impunity, just because he is an expert aware of the changes in sense perception.” This is because technology inevitably forces us to reframe our perspectives in ways that are uncomfortable to those who are used to the linear forms imposed on us by industrial and textual narratives. McLuhan dissected this mode of thinking in much of his work, which was written at the beginning of the electronic age and highlighted how the emerging media of the time, especially visual media, had reshaped the largely linear textual landscape. Film, television, and photography were often perceived as lower art forms in part because visualization was perceived as literally “cartoonish.”

The academic and literary elite saw the book as the highest form of art. This has resulted in an inbred bias against visual communication, in higher education particularly. We don’t teach our students how to visualize in part because the vast majority of faculty went through textual training in their undergraduate and, especially in, their graduate experience. That was certainly the case for me.

You see this deficit in a vast range of areas from the aforementioned presentations to textbooks littered with bad visualizations. There are exceptions to this and some disciplines are more forced, by necessity, to visualize their content. Outside of dedicated programs, however, there is little training in visual information creation and presentation. “Technology” programs often teach the mechanics of using software such as PowerPoint, Illustrator, or Photoshop, but there is often little thought given to the purpose and the power of these software packages to reshape narrative.

Why is this suddenly an issue? We now have increasing power to create visual narratives ourselves, and it is in our power to lift dialog out of the linear tyranny of text. This is my attempt to show what I can do with a visual creation tool. It has both a narrative and metanarrative function of illustrating what I’m talking about. It also demonstrates my (and its) limitations in trying to convey exactly what I’m talking about.

Going back to an insight from a great American technologist, Vannevar Bush, one of the key motivations for the computing revolution was to keep up with the increasingly complex, non-linear problems that were confronting society. While the Simple Linear path of text is the shortest route between thinking and understanding, more and more of our problems lie along the path that requires Holistic and Contextual thinking. Visual media are much better at creating an understandable representation of that complexity.

Textual narrative assumes there is a beginning, middle, and end to a story, argument, or problem. Visual narrative is far more fluid. It does a better job of showing the intertwingled nature of many of today’s problems. To cite just one example, there is no beginning, middle, or end of the global warming crisis. There are myriad inputs, combinations of solutions, and outcomes that are often poorly expressed in linear format. This is precisely the kind of problem that motivated Vannevar Bush, Doug Engelbart, JCR Licklider, and Ted Nelson to think about technology in the first place. Yet, we still approach learning and communication in much the same way as was done when they were writing decades ago.
So, how do we begin to address this critical challenge? First, we should enlist the talents of visual artists to explain the potential and unique challenges of visual storytelling. Scott McCloud makes a good start of this in his books and TEDtalk, which he gave a decade ago.
There are a lot of parallels between web comics and MindMaps as Randall Munro has repeatedly demonstrated. It’s all about manipulating perspective and visual representations, that when done well, fundamentally mess with your perspective on an issue. I often enlist my photography in my own visual storytelling, but this is just one way to create a visual narrative.

Graphics created through MindMapping software are a much simpler way to create a diagram or idea flow chart that can be incorporated into presentations. These can even be created live and on-the-fly during brainstorming sessions and meetings in order to capture the complex interrelationships of the discussions that happen (and that are often lost) in the linear albeit fragmented, nature of meeting minutes and notes. I am still looking for a truly collaborative way to make MindMaps. Some of the online mapping platforms such as MindMeister offer some promise for working collaboratively and persistently. There are still some frustrating limitations in this area, but I am confident that incremental improvements will increase the accessibility of visualization software.

The bigger problem, however, is our mental limitations in both teaching and thinking visually. Most classes that “teach” PowerPoint gloss over the narrative changes that it imposes on us through its transition from a linear textual narrative to a nonlinear visual one. They also fail to examine the information transfer capacities of various media. PowerPoint is software that complements a performance and often fails as a container for information. It needs to be augmented by more persistent visual and textual media. I’ve worked around this by creating websites as a mechanism to gloss my presentation; provide background linkages; and to create a persistent, living complement to what happens live. Slideshare fails to do this because it only gives you half of the presentation, the visual part, which may or may not stand on its own. Part of visual literacy is understanding how visual media complements other media, such as audio and text.

Finally, we need to start embedding design thinking into our processes. Design thinking is, by its very nature, closely tied to the visual. Not all design is based on images, but even textual design relies on layout and other visual composition techniques for its power. Most importantly, it teaches us to think about these issues in fundamentally different ways than simple critical thinking and textual composition do. These two strands need to be interwoven if we have any hope of preparing our students and ourselves for the coming challenges of the visual age.

In a sense, technology challenges us all to become serious artists. Those of us who teach or have taught have learned the power of a good visualization in presenting complex information to our students. As the world gets more complex, visualization becomes even more critical to our methods of teaching, learning, and communicating. The trick is not being afraid of it. Get out the finger paints. Try to tell your next story through pictures. If you mess up, play with it and refine it just like you would with text. Above all, apply a visual eye to your presentations, websites, and videos and be aware of the narrative shifts created by the media.

The Grader’s Dilemma

(Originally published on nmc.org on August 15, 2013)

In every class I teach, I struggle with some fundamentals of our industrialized education system that I cannot change but which seriously inhibit creative exploration of available information. I always dread being asked, “How do I get an ‘A’ in this class?” or even worse: “How do I pass this class?” I never seem to get this question: “What can I learn in this class?” This should not surprise me because our students have been well trained by the time they get to college. They see little connection between school and learning. Instead, it’s about beating the system. This is particularly true for most of my students who struggled in their K-12 classes and may have only graduated by the skin of their teeth. A fixation on grades is second nature to them (as it is to my own kids).

Grades have a pernicious effect on true learning and creative thought. As someone who has always loved learning for learning’s sake, I find this particularly frustrating. I have always personally been able to push the administrivia of learning to the background, in part because I never really feared failing a class in high school or college. My students are not so lucky and, as a consequence, evaluation becomes central to their educational experiences. Daniel Pink, drawing on decades of psychological research, shows fairly conclusively that external motivators like money and grades destroy our capacity for creative thought.

As a consequence, I feel like the industrialized educational system is always working against my educational goals. It is a lot harder to evaluate skills and assess final product when everyone is looking past that to what their final grade will be. I spend a lot of time and effort (it is often a central focus to my pedagogical strategy) trying to push grades to the background or at the very least to try to trivialize their effects but it’s a little like trying to hide green beans in chocolate cake. The taste can sometimes be disconcerting to the unprepared. I fight this battle with my own kids in K-12 and it’s hard with sustained effort, and even more difficult within the constraints of a 16-week class that meets once or twice a week.

In my most recent effort, I attempted to make “kinder, gentler” grading the focus. I did this by implementing a cumulative point system. No one failed assignments. It was all a process of accruing points. Furthermore, I wanted to achieve a certain level of gamification using insights from Tom Chatfield such as creating many small rewards and providing them with rapid feedback.

To achieve these goals, I gave each student a code and created a spreadsheet, which, in turn, created a bar graph to show how many points everyone had accrued relative to the rest of the class and relative to the bars necessary to achieve a grade.

Achieving rapid feedback was one area in which I failed the students. I was not able to turn around the grading fast enough to give them immediate feedback. Therefore, I don’t know if this aspect of the class was given a fair shake. As I discuss below, one issue that I encountered was the time required in developing a point system that did what I wanted to it to do. The delays in getting this finalized and workable put my grading way behind. Applying lessons learned in future semesters should alleviate this issue somewhat.

The other area that Chatfield mentioned, that of frequent, small rewards, actually caused complaints at the end of the semester is that spreading out the reward structure required constant attention on the students’ part. While we, as teachers, expect the students to put in consistent attention in the class, the reality is that most students want to be able to check in only on the week of a test or a paper deadline and essentially coast through the remaining weeks of the semester.

Even though I made expectations clear, the students were shocked about 2/3 of the way through the semester that they had failed to accumulate enough points. At this point, the point accumulations reflected their efforts posting on Google+ as well as their participation in in-class activities. To cite just one yardstick, I asked them to post twice on Google+ per week as a minimum activity. One post was in response to a prompt. The other was to bring in an outside source relating to the topic of the week. At that point in the semester (the 7thweek), they should have had a minimumof 14 posts. About 1/3 of the class had less than 5. I gave them opportunities to catch up point-wise by commenting on others’ posts but this was a real struggle for many of them. I did not allow them to go back and make new posts as this would have been unfair to those who did the work on time.

The second major part of my evaluation strategy was to be mindful of precisely what I was attempting to evaluate. The students and I had a frank discussion what kinds of skills they needed to be practicing in college and how the course could facilitate that. I introduced them to the National Education Association’s: “Four C” rubric as I think it encapsulates what I think is important to get out of college nicely and suggested that we use these four variables (Communication, Collaboration, Creativity, and Critical Thinking) to evaluate their performance. I broke it down as follows:

  • Communication – How well did students present themselves? These points were given for things like the quality and frequency of posts on Google+, quality of presentations in-class, and the clarity of their portfolio website.
  • Collaboration – How well did students work together to achieve the common goal of learning? These points were given for things like group self-evaluations for in-class debates, presentations, and commenting on Google+ posts.
  • Creativity – How effective were students in pulling together evidence into an argument? These points were given for presentation arguments, debate arguments, and the creative use of evidence in Google+ posts.
  • Critical Thinking – How reflective were students about the arguments they were presenting? These were the hardest points to earn. Students had to demonstrate self-awareness in arguments, an ability to see both sides of an issue, and to be able to integrate that into their presentations, posts, and portfolio.

The problem that occurred as a result of attempting to achieve this level of granularity was that I created four-headed hydra trying to translate the Four-C’s into a workable grading scheme. This was one of the key reasons that I didn’t get feedback to the class as quickly as I wanted to. I essentially ended up developing a manual Learning Analytics system to translate the variables into points. The net effect was that I forced myself into an incredibly complex grading system that took me half the semester to figure out. The extent to which I applied tech was limited creating a complete 12-page workbook in Numbers (it did better graphing than Excel). Frequent rewards meant that I had to deal with extremely small numbers and never really achieved the level of finesse that I usually demand from my grading.

Over and above the logistical hurdles that I created for myself, I don’t think the grading system taught the students much, if anything, about their relative skills in the four areas. I did discuss how I was assigning points while discussing grades within the class. However, I could tell the students were almost entirely fixated on the total points, not how they could earn points in communication versus critical thinking, for instance.

My struggles with the grading system and my ultimate failure in developing a more constructive system was perhaps the most disappointing result from this part of the experiment and goes back to my original dilemma. I never figured out how to move the discussion beyond, “How do I pass this class?” to “What can I learn that might be useful to me?”

I am not going to be able to get beyond the fundamental realities of the need for a final grade in the class as long as the larger educational system uses the transcript/degree as the final yardstick of educational achievement. Perhaps a more successful application of gamification principles would at least make this part of the class more fun and trivial. The students themselves live with fundamental contradictions in their own attitudes toward their educational investments. On the one hand, they play the grading game with seeming indifference when it comes to the value of an individual class. On the other hand, they are totally fixated on their final grade as the only valuable thing they get out of wasting their time in a class they don’t want to take in the first place. New Media may give us some routes forward but until it undermines these fundamental contradictions in assessment, technology’s transformative power will be very limited. Solving the grader’s dilemma may require adjustments beyond the capacity of any individual educator to achieve but I’ll keep trying. I’m stubborn.

 

Just Let it Happen: Living With Open-Ended Outcomes

(Originally Published on nmc.org March 2016)

In “Teaching Creativity – Not Conformity,” I began by positing that we need to encourage exploration through questioning rather than providing answers to our students (and employees). Since then, Kevin Kelly has reemphasized the same theme by identifying the skill of questioning as one of the key trends that will shape humans in our technological future. We have been talking this talk for years now. The exciting thing is that technology is now giving us tools to start walking the walk.

In an age driven by “quantifiable” accountability, however, many of our present organizations continue to struggle with the concept of open-ended outcomes. If we stress a questioning approach, particularly in a programmatic context, it is often seen as a risk that is hard to quantify unless we provide some sort of predictable, often quantified, outcome. Uncertainty of outcomes is often viewed as not being scientific or data-driven. That is only true if we are looking for overly simplistic answers in defining success. We can still measure outcomes – but they are often tangential to the original creative exercise. Sounds a lot like teaching, does it not?[LINK: http://www.nmc.org/blog/teaching-creativity-not-conformity/]

In 2010, I began facilitating the New Media Seminar for faculty at HCC’s Northwest College, which focuses on how the world is changing and ways in which we as educators need to adapt to those changes. Initially, I was attracted to the concept developed by Gardner Campbell because I felt it provided a nice venue for free discussion about technology and the development of pedagogy. What I did not realize at the time was the extent to which it developed questioning about the status quo of what we are doing in the classroom. Many faculty members who have participated in the seminar found it a strangely liberating experience from their daily experience precisely because of its open-ended nature. It was always a challenge, however, to explain that power to those looking at the course from the outside.

I am often surprised at how unwilling people are to question the seemingly predictable flow of their existence in order to leave room for the unexpected outcome. I always start my undergraduate government classes asking my students why they are there. It amazes me how few of them have even pondered the question. A lack of purpose turns college into essentially a hazing experience whose main purpose is to demonstrate perseverance, not learning, and all too often faculty aid and abet that by passing them through classes without giving them a clear reason to engage in learning. Furthermore, as we design courses and programs it is often easier to just go with the flow rather than risk the unexpected or ambiguous. Like training, answers give us neat little boxes in which to put everything. Teaching has the power to augment us as human beings. Giving students and faculty the freedom to creatively explore without a set purpose is liberating to some, incomprehensible to some, and threatening to others.

Makerspaces perhaps pose the biggest threat to the status quo: if they live up to the true ideals of making, outcomes are truly uncertain. In January 2016 we opened the D-Lab, the first of our makerspaces at Northwest College. The critical aspect that characterizes our D-Lab is that it is essentially a “rule-free” zone designed to promote creative problem solving. Questioning is driving the very development of the space, as we have added and adapted equipment and supplies based on community inquiries. Many of our spaces are being designed around the concept of project-based learning and our new building, the West Houston Institute, was explicitly designed to foster innovation and creative thinking. [LINKhttp://ideaspaces.net] The goal is to lower the barriers to entry as much as possible and then get out of the way.

We also recognize that all of these plans will falter if we cannot work to move HCC’s culture away from the rigidity that characterizes industrial modes of education. Training is a natural outcome of this kind of thinking. The D-Lab forms a gateway to a post-industrial mode that nurtures creative thought that is liberated by good teaching. To be clear, this is a hard task that will take years to manifest any appreciable impact institution-wide. Meanwhile, we are already seeing people gravitate to the freedom of the D-Lab in unexpected and unconventional ways.

Recently, my lab techs decided to build a virtual sandtable using an old projector and an Xbox Connect. They improvised this rig using zip ties and rubber bands. Believing it looked unsafe, our AV contractor offered to provide a proper mounting solution (costing hundreds, if not thousands, of dollars and taking months to implement, no doubt). I don’t blame him. He’s never seen activity like this at our college before. The space is generating a new form of agile activity not previously seen at our college.

The D-Lab has shown me that there is a genuine hunger for independent thought and the creativeenterprise. Technology merely provides the mechanism to escape the rigid structures of the industrial world. This creativehunger is precisely what we need to harness bothinternally and for our students if we want to be successful in a world characterized by automation and increasingly complex problems. We are all creative teachers and learners. We just need to have that unlocked. I am seeing that happen every day in spaces like the D-Lab. It gives me hope that we will finally move away from the training mode to the creativemode.

We are currently in the process of developing business plans for the programs we envision at our new building, the West Houston Institute. Unlike the New Media Seminar, which cost relatively little other than time, and the D-Lab, which came together out of spare project funds, the Institute is a $50 million project before staffing costs. With scale comes scrutiny and a search for clarity by decision makers. While this approach is completely understandableand a responsible use of taxpayer money, a space designed around open-ended inquiry and uncertain, creative outcomes often challenges this kind of thinking.

It is relatively easy to figure out a hard set of numbers around a Collaboratoriumor conference space that can be rented out to business. At the same time, it is more difficult to demonstrate concrete outcomes around how these kinds of spaces also foster open-ended activities such as brainstorming projects and technology competitions. Activities in the makerspace or informal collaboration areas face similar challenges. If they are not associated with a particular program, it can be difficult for people to wrap their heads around the spaces’ purpose. Is the idea to let people play around? To what end? Quantifying qualitative outcomes is one of the central challenges of educational measurement and it is particularly acute in these kinds of circumstances.

The best argument to make is that this creates a very compelling learning environment, is a fun way to teach, and, perhaps most of all, creates critical 21stCentury skillsets in our students (and faculty). This approach fits into of the overall trend of refocusing around demonstrating skills rather than credentialing that is starting to be discussed throughout education.

One of my pet projects, the Teaching Innovation Lab (TIL) [LINK: http://ideaspaces.net/2016-innovation-loops-ideaspaces-presentation], addresses this challenge as well. The purpose of the TIL is to build upon the success of the New Media Seminar to create an open-ended venue for faculty to “play” with their teaching and share those experiences with their colleagues both inside and outside HCC. We also introduce rigor through data collection and analysis as well as structured workshops and other activities. Where faculty take it from there is up to them, however. Unlike many professional development projects, there is no defined fixed outcome. If it makes things better, it is a win.

I am excited about the potential for creative unpredictability of all of these efforts, but I can see where it runs counter to desires to establish standards around “good teaching” by accrediting agencies and state education boards. I do not believe there is one “right” way to teach, or at least I do not believe we are anywhere close to understanding what that is yet. Putting that notion into a business plan for the TIL is therefore presenting unique challenges. Some flexible thinking will be required all around. It is difficult to imagine quantifying exploration and unexpected outcomes. We can build a runway, but where flight takes our faculty and students is their magic, not ours. In other words, we can measure results in the context of skills acquired, but not necessarily predict them. That sounds amazingly like teaching to me.
