AllThingsD Early Adopters ran a quote in their Voices section from an article at PCPro that reads like a page right out of Marshall McLuhan. Echoing McLuhan’s return of acoustic space and the role of the mosaic in everyday life, Dr Rosie Flewitt of the Open University comments on how the modern learner might be shifting from sequential linearity toward a simultaneous gestalt:
“E-learning experts argue that withholding computers at a young age could actually deprive children of modern communications skills. ‘One area of literacy that’s changing is the order in which things are presented – it isn’t linear, it’s organised spatially, and often some meaning is carried in the design, layout, images, sounds, movement, subtle changes in colour in a game – it’s all part of what literacy is in today’s world,’ says Flewitt. ‘These are fundamental changes to operational literacy, the biggest since the printing press.‘ ”
Naturally some question is left as to whether this effect is limited to young children as a group or if one can detect a tendency toward acoustic involvement among younger participants in college classrooms and corporate training centers. The main point, however, is that linearity might already be optional in the classroom, where new and different styles of presentation and involvement might be called for in order to better reach the audience.
To contrast Dr Flewitt’s comment on linear versus spatial literacy, consider this synopsis of McLuhan’s acoustic space by Library and Archives Canada:
“The key characteristic of acoustic space is that it engages multiple senses at the same time. It does not demand that objects be dissected to be understood; rather, the multiple parts co-exist simultaneously. To understand acoustic space, you must perceive all of it, not focus on one part. In other words, acoustic space demands that you apprehend figure and ground simultaneously, that the senses work together. McLuhan believed that oral cultures existed in acoustic space since their primary mode of communicating was speech.”
In this interview with Nina Sutton, Mcluhan explains the rise and dominance of visual space from the phonetic alphabet forward: McLuhan on Acoustic Space.
As a sidebar it is interesting to note that McLuhan eventually dropped the use of the term Global Village from his work preferring the term Global Theatre instead. Apparently Global Village goes back to the advent of radio while the notion of the Global Theatre is more a part of Sputnik, television and modern global communications.
A recent study from researchers Louis Deslauriers, Ellen Schelew and Nobel Laureate Carl Wieman suggests that the Methuselah of instructional technologies, the venerable broadcast lecture, might finally be showing signs of going the way of geocentricity and the four humors. Applying methods taken from the theory of “deliberate practice” by psychologist Anders Ericsson, the research team introduced a more interactive, discussion-based and assessment-oriented approach to a physics class that strongly implies major improvements to science and engineering instruction in general.
The setting for the study involves two groups of electromagnetics students (control: 267; test: 271) wherein both were given the same learning objectives and enjoyed the same pedagogical approach (but not the same instructors) for the first 11 weeks of instruction. On week 12, Deslauriers and Schelew (both of whom have limited teaching experience) jumped into the fray and according to the BPS Research Digest lead the test group utilizing “…discussions in small groups, group tasks, quizzes on pre-class reading, clicker questions (each student answers questions using an electronic device that feeds their answers back to the teacher), and instructor feedback.” And, what is especially important to note here: there was no formal lecturing. According to the researchers the object of the game was:
“…to have the students spend all their time in class engaged in deliberate practice at ‘thinking scientifically’ in the form of making and testing predictions and arguments about the relevant topics, solving problems, and critiquing their own reasoning and that of others.”
In contrast to the test group, the control group went on learning the same material in the normal (typically passive) fashion epitomized by classroom lectures for probably the last 900 years. The students, however, apparently noticed a difference. As quoted in the BPS review:
“Student engagement (measured by trained observers) and attendance in the control group was unchanged in week 12 compared with earlier weeks. In the intervention group, attendance rose by 20 per cent and engagement nearly doubled.“
The critic or cynic might assert that the presenters were putting on a better show in the test case. What about student performance? On the first day of class after week 12 both groups were tested on what they had learned the previous week. In addition, as part of the preparation for the test, both groups were given all the materials used by the intervention group, i.e., the clicker questions, group activities and problem sets, and exercise solutions. The results are as striking as the jump in student engagement:
The non-lecture intervention group averaged 74 percent correct while the control group averaged 41 percent. Factoring out random guessing, the intervention group did twice as well as the traditional lecture students (the effect size being on the order of 2.5 standard deviations!). Not to be downplayed, student reviews rated the non-lecture approach very positively. Ninety percent said they enjoyed the process.
Jeffrey Mervis writing for the AAAS ScienceNow magazine quotes Wieman as saying:
“ ‘It’s almost certainly the case that lectures have been ineffective for centuries. But now we’ve figured out a better way to teach’ that makes students an active participant in the process, Wieman says. Cognitive scientists have found that ‘learning only happens when you have this intense engagement,’ he adds. ‘It seems to be a property of the human brain.’ ” – Jeffrey Mervis, A Better Way to Teach?
Given the novelty of the technique and the overt nature of the study there has been some criticism of the results based on the Hawthorne Effect. The research team discounts this criticism on the basis that the intervention only occupied a small percentage of the students’ overall daily learning activities. Drilling a little deeper, psychology professor Daniel Willingham (as recounted in Carey below) cautioned that the study might not have been designed well enough to discern which of the factors introduced in the new classroom style account for the gains in student performance and to what degree.
In what might be one of the clearest victories for proponents of the Inverted Classroom the research team is optimistic of the result and reckons it can be generalized to a wide range of post-secondary courses. No doubt further studies can be expected. The study in question is supported by a $12 million dollar program to investigate new methods to enhance science instruction using research-backed methods.
At first glance Salman Khan appears a most unlikely revolutionary. Although well educated (note: he is neither an educator nor a psychologist) he has nonetheless, and from most accounts, single-handedly ignited a revolution in teaching that any “real” educator, government administrator or instructional designer would be proud to lay claim to.
What started as simple private tutorials in math for his cousins – utilizing what he describes as about $200.00 in computer accessories and shareware – Khan drew upon his innate interest in education (along with perhaps his own personal frustrations as a student) to craft a series of screen capture how-to guides for solving high school math problems. As word spread among friends and family members, viral interest forced Khan to move his homespun videos to YouTube to service his burgeoning audience, completely for free. The rest, as they say, is history.
At present the Khan Academy (a not-for-profit educational organization founded in 2006) has served over 51 million views from a library of over 2200 videos. In addition to math and physics, topics now embrace history and biology. School districts and major corporations are attempting to use and develop his methods for their own internal applications. Donations from private sources and the likes of Google and the Gates Foundation have subsequently allowed Salman Khan to quit his day job and devote his energies full-time to the development of his Academy and the distribution of educational programs worldwide (“providing a high quality education to anyone, anywhere”).
Looking over Khan’s presentations on his methods you begin to wonder what makes the Khan Academy so successful. After all, this isn’t the result of a major educational research program, a sweeping government initiative, or a mass popular movement in educational reform. Further, what makes the Khan Academy even more interesting is that Khan’s tutorial method is not so much ingenious as it is ingenuous.
In several of his talks Khan is fairly straightforward in his assessment of what makes his method work. First and foremost, as Khan attests, each of the videos offers a lesson on a single concise topic (a “concept”) for no more than about 10 minutes. One key idea, cut in a bite-sized chunk, for a period not to exceed the boredom threshold of the average viewer. Given that the videos are recorded and stored online, the presentations can be played any time and repeated as needed by the student until he or she feels comfortable to move forward.
Another feature of the tutorials is the general tone they are given in. As Khan describes it, they feel like they are coming more from a friend than a teacher. You have a sense that Khan is there with you, sitting by your side, leading you through the problems with a pencil and paper. They are down-to-earth, enthusiastic and rigorous without a trace of giddiness, pomposity or pedantry. The student feels like “…there is an individual who cares about you,” Khan says. The student comes away with a sense that the instructor wants to help him or her over the obstacles in the landscape because he has been in the student’s place himself and sympathizes with the struggles that lay ahead.
Drilling down a layer into the Khan Academy’s unique style reveals even more about what makes the “secret sauce” special. Each of the bite-sized topics that are referred to previously are in fact carefully culled and curated learning objects. The trick, of course, is to first know the subject well enough to select which topics to present and in what order. Following that, the teacher must distill the concepts to their absolute essence.
This distillation process is, to all who have tried it, much harder than it looks. In fact, the ability to select and summarize complex material and ideas, rather than resorting to the indiscriminate slathering of a PowerPoint slide with bullets, might be one of the hallmarks of an educated mind. Clearly, Khan groks it.
Despite the thought and planning that goes into Khan’s presentations they can hardly be accused of being over produced. This is not Pixar doing technical training. If anything, the digital blackboard and colored chalk renderings show the human side of learning and mastery. The notes and diagrams often appear rough and awkward, but they are at the same time quite genuine, funny and sometimes – to the advantage of the learner – mistaken. As Khan explains it, he is often in the place of the learner and, in contrast to many schools and universities, has not rehearsed the solution beforehand, offering the student the patented procedure. Instead he lets the students witness his own thought processes as he wrestles with the problems and sometimes wanders down the wrong path from which he has to back out and start again – just like a real student.
Nowhere in Khan’s methods can be found any of the bells or whistles of modern post-industrial pedagogy. No Flash animation, interactivity, games, social networking tools, 3D graphics or monolithic learning management systems are to be found. In fact there is little beyond a virtual blackboard and some equally virtual colored chalk. You don’t even see Khan’s face.
The faceless almost tactile sketches and equations provide little distraction and promote focus on the material. This decidedly low-tech solution to training might harken back to ancient watch-me-do-it tribal methods but its effectiveness is not lost on Khan’s students, many of whom write to express thanks that they are not only mastering their classes for the first time but excited about the subjects as well.
Khan’s approach is to teach for academic competency. That is, he instructs in the methods and procedures that assist the student in passing standardized tests and formal exams. After the student completes a module, test problems are offered through a program that Khan designed himself that acts to monitor student progress and flag trouble areas for the teacher. The student is asked to correctly answer 10 problems in a row before moving to the next module. This final process closes the instruction, feedback and assessment loop in Khan’s method and further acts to eliminate the small voids in understanding that can multiply as the student moves forward. Interestingly YouTube assists in the process as well, offering statistics on usage and attention.
One of Khan’s own revelations about his method is telling: it’s so simple and effective that he does not see why anyone needs to give live lectures anymore.
Although he does not refer to it by name, Khan points to (and his method directly parallels) the use of what is commonly called the Inverted Classroom. In an inverted classroom recorded presentations impart new information prior to class while class time is taken up with teachers and peers solving problems (or “doing homework”) quite in reverse to what is traditionally done in schools and training centers.
The results of this method have so far been compelling. Both teachers and students benefit. Teachers benefit because more of their time is spent in directed remediation (particularly if they use Khan’s monitoring software), problem solving and exploration of the material. Students like the inverted classroom because it potentially transforms class time into something useful and interesting. In Khan’s case the testimonials from parents, teachers and students are hard to ignore. His academy and tutorials do work.
More needs to be seen to ascertain whether the Khan Academy represents the future of education as some claim. But what is clear is that it stands as a forceful reminder of what can be done to improve the instruction of certain skills and particular subjects while simultaneously improving the classroom experience for everyone.
I don’t think this is much taught in Instructional Design courses, but the design of a presentation conveys information in and of itself to the audience. This is due in large part to the fact that all the elements of a course or presentation (including the presenter) constitute a Gestalt that is projected to the audience.
Good design matters because good design leads to clarity. And clarity facilitates perception.
The design elements often constitute the ground in the figure-ground relationship of the medium, but the whole package conveys a message. The medium is the message.
As an example of how design sends nonverbal cues to the viewer, take a look at the short talk by John McWade of Before & After Magazine. Although taken completely from the design world the example captures the effects of font, color and shape passed as a subliminal message to the unsuspecting eye.
It is not hard to cite these effects in educational media and presentations. How often does a slide, presentation or workshop exercise say “boring” or “we don’t care” or “this is not important” or “this is hard to understand” to an audience? Media evoke reactions from the viewer and the reactions are often affective in nature. Connie Malamed at the eLearning Coach puts it this way:
“This has strong implications for learning, because of the impact positive or negative feelings have on motivation, comprehension and retention.”
We design educational media for a reason. Well designed media lower the barriers to comprehension and assist the mastery of new skills. Things that detract from these goals include boring and inept graphics, awkward symmetry and poor layouts, illegible typefaces, abrasive or boring color schemes, and too much information.

I’m glad that someone has gathered the courage to say this out loud: Instructional design in the 21st Century is not about events, it’s about experiences. No doubt from the looks of things, instructional design (ID) is in the natural throes of shaking off the learning events metaphor imposed on it by the educational psychologists of the Industrial Revolution, but learning and development thinkers like Charles Jennings hope that we can hasten it along for the sakes of our students and ourselves. For Jennings the shift from working with the hands to working with the head is a key indicator that promotes the need to move from events toward processes:
“Undoubtedly instructional design is crucial if the mindset is learning events – modules, courses, programmes and curricula. However, if the mindset has stretched beyond event-based learning to where most learning occurs for workers, which is in the workplace at the point-of-need, where process-based learning serves best – and where learning through doing and learning as part of the work process happens, then ID takes on a whole new dimension.”
Jennings posits the notion of “learning” held by inhabitants of the 21st Century as moving from a habitat of “knowledge” to a new one of “behavior.” The medium is the message. It’s not about content anymore.
“For years we’ve been led to believe that ‘learning’ meant acquiring knowledge. If knowledge acquisition is the end-game, then the logical conclusion was to provide information that could be turned, whatever the magic employed, into knowledge in the recipient’s head. Believe me, the old idea that data becomes information which in turn becomes knowledge and finally transmogrifies into wisdom has been debunked years ago. We use our knowledge and experience to interpret data and information. Wisdom comes to a few only after years of experience.”
Jennings reminds us that Ebbinghaus and the Forgetting Curve aside, we need to observe learning in action to make intelligent assessments about its effectiveness. Experience and practice are the keys and, as such, instructional designers need to become interactivity designers.
“Good ID will result in the design of experiences that can build capability and learning far more quickly and effectively than by filling heads with information and ‘knowledge’ and then hoping that will lead to behavioural change.
We need designers who understand that learning comes from experience, practice, conversations and reflection, and are prepared to move away from massaging content into what they see as good instructional design. Designers need to get off the content bus and start thinking about, using, designing and exploiting learning environments full of experiences and interactivity.”

If you are thinking of using social media in a class to help build useful collaborative connections, retire the fears of shy students and introduce the same engagement you see in sites like Facebook, think again. A recent study by the Lab for Social Computing at Rochester Institute of Technology suggests that the use of social media in classrooms might yield little effect in improved communications and enhanced connections between students. The study into the effects of social media was conducted as part of a course on the use of social media and tools. It included contributions from online learning and course management systems and discussion groups that were proposed to enhance instruction, improve communication and facilitate connections between the students and course content. The results indicate that poor social acumen in the face-to-face interactions might be mirrored in the (more) virtual social medium. What’s more, echoing teacher and educational social media researcher Michael Wesch, the RIT study suggests that the educational use of social media may have to be learned:
“…the educational use of social media may not counteract poor social connections that are seen in face-to-face communication or elicit the same impacts seen in the use of social media sites such as MySpace and FaceBook.”
Researcher and team leader Susan Barnes comments on the hopes and goals of social media in the educational environment relative to her team’s findings:
“Many social media advocates have argued that the use of these tools in classroom settings could greatly enhance interaction and learning and assist shyer, more reserved students in becoming more involved, as has been seen in other online environments. However, our findings show that the incorporation of social media had no measurable impact on social connections, to the point that students did not consider other members of the class to be part of their social network.”
The RIT research team plans to expand the study to consider different educational formats and additional social media applications in an effort to determine the effects and differences of social media from traditional classrooms. The intent is to help educational planners and instructional designers better use social media in course development and delivery.
“The issues surrounding poor social network construction within online educational environments points to greater opportunities to examine how technology and mediated software can be better designed to suit the types of communication and interactions desired by our students.” – Christopher Egert, co-author
What’s the best way to teach math? It’s a big question, but research at Ohio State University’s Center for Cognitive Science challenges a commonly held (though perhaps informal) notion in instructional design that concrete examples aid the learning and application of mathematics more than abstract proofs and representations. The idea that mastery of abstract quantities and concepts actually provides the learner with a better, i.e., more practical, set of tools for problem solving seems counter-intuitive, but researcher Jennifer Kaminski and her team believe they have proof. Kaminski et al. looked at whether students who received instruction using concrete examples performed differently from those who were encouraged to master the concepts abstractly. What they found was that the group who were instructed in more concrete terms and examples were less able to apply the knowledge to new situations.
“These findings cast doubt on a long-standing belief in education…. The belief in using concrete examples is very deeply ingrained, and hasn’t been questioned or tested.” – Vladimir Sloutsky, co-author
“Teachers often use real-world examples in math class, the researchers said. In some classrooms, for example, teachers may explain probability by pulling a marble out of a bag of red and blue marbles and determining how likely it will be one color or the other.
But students may learn better if teachers explain the concept as the probability of choosing one of n things from a larger set of m things.”
This research might help explain why so many people find word problems (and the semantic or linguistic use of mathematics) so daunting in mathematics and physics. In Kaminski’s words:
“The issue can also be seen in the story problems that math students are often given. For example, there is the classic problem of two trains that leave different cities heading toward each other at different speeds. Students are asked to figure out when the two trains will meet.
The danger with teaching using this example is that many students only learn how to solve the problem with the trains.
If students are later given a problem using the same mathematical principles, but about rising water levels instead of trains, that knowledge just doesn’t seem to transfer.”
Sloutsky sees a role for word problems, however, just not as an instructional aid:
“It is very difficult to extract mathematical principles from story problems. Story problems could be an incredible instrument for testing what was learned. But they are bad instruments for teaching.”
Kaminski’s and Sloutsky’s study should provide useful insight for those looking at ways to better teach subjects like mathematics, physics, signal analysis, algorithm design, dynamics, logic or economics. It should be noted that Kaminski and Sloutsky worked with Andrew Heckler of Ohio State’s Physics Department on parts of the study.
Chip and Dan Heath, authors of the popular book Made to Stick: Why Some Ideas Survive and Others Die, have applied key principles of their stickiness theory to teaching. The resultant 13 page e-book is available in PDF format at their web site or on scribd.com as a free download.
Borrowed from their research, the brothers Heath apply six traits that make ideas (and teaching) stickier. Sticky ideas are:
SIMPLE.
“This process of prioritization is the heart of simplicity. It’s what we call ‘finding the core.’ Simplicity doesn’t mean dumbing down, it means choosing. Some concepts are more critical than others. And as the teacher, you’re the only one who can make that determination.”
UNEXPECTED.
“Piquing curiosity is the holy grail of teaching.” Cialdini said, “You’ve heard of the famous Ah ha! experience, right? Well, the Ah ha! experience is much more satisfying when it’s preceded by the Huh? experience.
So how do you create the ‘Huh?’ experience with your students? George Loewenstein, a behavioral economist, says that curiosity arises when we feel a gap in our knowledge. Loewenstein argues that gaps cause pain. When we want to know something but don’t, it’s like having an itch we need to scratch. To take away the pain, we need to fill the knowledge gap. We sit patiently through bad movies, even though they may be painful to watch, because it’s too painful not to know how they end.
Movies cause us to ask, What will happen? Mystery novels cause us to ask, Who did it? Sports contests cause us to ask, Who will win? Crossword puzzles cause us to ask, What is a 6-letter word for psychiatrist? Pokemon cards cause kids to wonder, Which characters am I missing?
One important implication of the ‘gap theory’ is that we need to open gaps before we close them. Our tendency is to tell students the facts. First, though, they must realize they need them.”
CONCRETE.
“Concreteness etches ideas into our brain—think of how much easier it is to remember a song than a credit card number—even though a song contains much more data!”
CREDIBLE.
“For an idea to stick, it needs to be credible. YouTube-era students don’t find it credible that hanging out outside, for a long period of time, alone, could be conducive to great thinking. So how do you combat their skepticism? You let them see for themselves. It’s like a taste test for ideas.”
EMOTION.
“That’s what Emotion does for an idea—it makes people care. It makes people feel something. In some science departments, during the lesson on ‘lab safety,’ the instructor will do something shocking: They’ll take some of the acid that the students will be handling and use it to dissolve a cow eyeball. A lot of students shudder when they see the demonstration. They feel something. Lab safety ‘dos and don’ts’ don’t grab you in the gut, but a dissolving eyeball sure does.”
STORY.
“The second surprise about stories is why stories, even boring stories, are so sticky. The answer starts with some fascinating research done on ‘mental simulation.’ Brain scans show that when people imagine a flashing light they activate the visual area of the brain; when they imagine someone tapping on their skin they activate tactile areas of the brain. The activity of mental simulation is not limited to the insides of our heads. People who imagine words that start with “b” or “p” can’t resist subtle lip movements, and people who imagine looking at the Eiffel Tower can’t resist moving their eyes upward. Mental simulation can even alter visceral physical responses: When people drink water but imagine it is lemon juice, they salivate more. Even more surprisingly, when people drink lemon juice but imagine it is water, they salivate less. … The takeaway is simple: Mental simulation is not as good as actually doing something—but it’s the next best thing. And, to circle back to the world of sticky ideas, what we’re suggesting is that the right kind of story is, effectively, a simulation. Stories are like flight simulators for the brain.“
The free booklet gives practical suggestions and examples of how to use “stickiness” to improve lessons and teaching. The authors are quick to remind readers that the principles are pragmatic design guidelines for better teaching not just theories for the way instructional design works. “Teaching that Sticks” is an entertaining and informative read for anyone who designs, writes or presents classes or educational material. A companion booklet “Making Presentations that Stick” is also available.
Although I find that teaching the history of a subject is often a big help in understanding its present state, recent reseach from Amsterdam suggests that using illustrations (drawings and diagrams) in the teaching of history might have no positive effect on learning. Dr Maaike Prangsma and associates looked at the effectiveness of using various illustrations in the teaching of history and found that no discernible differences could be found in test results between illustrated and plain text presentations immediately after the instruction was delivered or six weeks later. Interestingly, the students did say that on the whole the graphics made the learning easier, leading investigators to conclude that the illustrations might enhance the efficiency of the training. The British Psychological Society’s report on the study claims that:
“The key finding was that the nature of the learning task made no difference to learning outcomes. The plain text version appeared to be just as effective as the versions involving a diagram, drawings, or combination of the two. The researchers were surprised by this result and offered a number of possible explanations. For example, perhaps the initial text on the fall of the Roman Empire was so effective it undermined any possible differential effects from the learning tasks. Or perhaps graphics aid science learning because there are clear rules about what different signs and symbols mean, whereas history lacks these conventions and the students therefore didn’t know how to use the visual aids.”
In agreement with a basic philosophical tenet underlining this blog, the authors of the study concur that garnering a positive appreciation of the subject matter presented is not to be ignored:
“The goal of educational motivation is not only to make learning more efficient … or effective … but also to make learning more pleasant such that the affective learning experience is more satisfying and learners will want to learn more.”
