“President Obama Announces More Key Administration Posts

Edward Tufte, Appointee for Member, Recovery Independent Advisory Panel
Edward Tufte is Professor Emeritus of Political Science, Statistics, and Computer Science at Yale University. He wrote, designed, and self-published The Visual Display of Quantitative Information, Envisioning Information, Visual Explanations, and Beautiful Evidence, which have received 40 awards for content and design. He is a Fellow of the American Academy of Arts and Sciences, the Guggenheim Foundation, the Center for Advanced Study in the Behavioral Sciences, the Society for Technical Communication, and the American Statistical Association. He received his PhD in political Science from Yale University and BS and MS in statistics from Stanford University.”

From ET:

“I will be serving on the Recovery Independent Advisory Panel. This Panel advises The Recovery Accountability and Transparency Board, whose job is to track and explain $787 billion in recovery stimulus funds:

‘The Recovery Accountability and Transparency Board was created by the American Recovery and Reinvestment Act of 2009 with two goals:To provide transparency in relation to the use of Recovery-related funds.
To prevent and detect fraud, waste, and mismanagement.
Earl E. Devaney was appointed by President Obama to serve as chairman of the Recovery Board. Twelve Inspectors General from various federal agencies serve with Chairman Devaney. The Board issues quarterly and annual reports to the President and Congress and, if necessary, “flash reports” on matters that require immediate attention. In addition, the Board maintains the Recovery.gov website so the American people can see how Recovery money is being distributed by federal agencies and how the funds are being used by the recipients.

Mission statement: To promote accountability by coordinating and conducting oversight of Recovery funds to prevent fraud, waste, and abuse and to foster transparency on Recovery spending by providing the public with accurate, user-friendly information.’

I’m doing this because I like accountability and transparency, and I believe in public service. And it is the complete opposite of everything else I do. Maybe I’ll learn something. The practical consequence is that I will probably go to Washington several days each month, in addition to whatever homework and phone meetings are necessary.”

A new study conducted by Dr Clare Wood, of Coventry University, and the British Academy has addressed whether “texting” has a pathological effect on learning to read and write. Dr Wood, who is a specialist in reading development, looked at a group of 8–12 years olds over the course of the school year and has concluded that far from eroding basic reading and writing skills, the activity may be a sign of their mastery. The results come as a surprise to many who assume the practice to be a clear sign of the decay of basic literacy. From the university report on the research:

“We began studying in this area initially to see if there was any evidence of association between text abbreviation use and literacy skills at all, after such a negative portrayal of the activity in the media. We were surprised to learn that not only was the association strong, but that textism use was actually driving the development of phonological awareness and reading skill in children.  Texting also appears to be a valuable form of contact with written English for many children, which enables them to practice reading and spelling on a daily basis.”

The study goes further to suggest that the degree to which a user has mastered texting may be indicative of his or her overall reading ability:

“The research, carried out on a sample of 8-12 year olds over an academic year, revealed that levels of ‘textism’ use could even be used to predict reading ability and phonological awareness in each pupil by the end of the year.”

Dr Wood is hoping that the results of the study change the way people look at texting in relation to phonetic literacy:

“In short, we suggest that children’s use of textisms is far from problematic. If we are seeing a decline in literacy standards among young children, it is in spite of text messaging, not because of it.”

For those unfamiliar with texting, this post is re-written in Lingo below:

According to technology blog CNET, the educational content wing of Apple’s iTunes Music site, iTunes University,  passed a milestone of over 100 million downloads this week. iTunes University is part of a mobile learning and content distribution service available through Apple’s iTunes application. As stated by Apple on their mobile learning site:

“Today’s students expect constant access to information—in the classroom and beyond. Which is why more and more faculty are using iTunes U to distribute digital lessons to their students. And now, with the 3.0 software update for iPhone and iPod touch, iTunes U is directly accessible over both cellular and Wi-Fi networks through the iTunes Store.”

Interestingly, according to CNET, one of the most popular draws on iTunes University’s bandwidth is the much esteemed Open University (OU) in the UK that had earlier tried and failed to launch an American campus in the late 1990s. A brief report of the OU’s foray into the American educational market is provided here.

The Open University is incorporated by Royal Charter in the United Kingdom but operates internationally. According to its web site the OU serves over 150,000 undergraduate and 30,000 postgraduate students. 25,000 are outside the UK. It is generally considered “the world’s first successful distance teaching university” and the United Kingdom’s only university dedicated to distance learning.

The iTunes University download service is popular among many other universities as well. Contributors include: Stanford University, Princeton, Yale, MIT, UC Berkeley, and the New Jersey Institute of Technology. A partial (and growing) list of schools providing content can be found here. Given it s recent growth and overall wide acceptance, iTunes University appears to have become a standard tool for distribution of audio and video content among American colleges and universities.

Measured “return on investment” and “training effectiveness” are two of the business metrics commonly used to yoke trainers and developers in business and government training centers around the globe. “Is the training effective?” and “Is it worth the cost?” are standard queries at development meetings and design reviews. Knowledgeable designers and managers invoke Bloom, Kirkpatrick and things like ADDIE to promote development of effective training, little knowing that Pygmalion might provide the help they need.

A little over 40 years ago, Robert Rosenthal and Lenore Jacobson performed a simple and ingenious experiment in a California school that jolted educational psychology. Dubbed the Pygmalion Effect (after the play by George Bernard Shaw; later the musical and movie My Fair Lady) the experiment showed that the effectiveness of teaching was largely determined by the belief of the teacher in the students. That is, all things being equal, if a teacher believes the students are exceptional, they will tend to match the expectation. Surprisingly perhaps, this “effect” has been replicated many times since its inception and has garnered support from similar studies done in colleges, industry and the military. What Pygmalion describes might be taken as the equivalent of the Placebo Effect in education, but it might just as well be a re-coining of the psychotherapeutic expression “you have to believe in the Process” directed toward the classroom.

What Rosenthal and Jacobson did in their study was give teachers false information about their students based on what they said was an advanced test to determine future performance and achievement. In reality they administered a standard IQ test, randomly selected a group of students without regard to the test results, told the teachers these students were going to bloom in achievement and sat back and noted the results. At the end of the school year the students were tested and the results showed that a significant number of the “bloomers” had in fact made unexpected gains in academic performance and behavior. In fact, tests of the same students two years later showed that they carried and maintained this advantage over that time.

Interestingly, while accounts of the first study did not include details of what went on in the classroom while the study was underway, written reports by the teachers themselves indicate that no special measures, programs or materials were provided to assist the “bloomers” in learning or to enhance the classroom experience. What Rosenthal and Jacobson concluded the “bloomers” got that the control group missed were clear signs of approval, more chances to interact with the teacher and patient acceptance, all moderated unconsciously by of the beliefs of the teacher.

Over the years the Pygmalion Effect has come under scrutiny by many researchers and has been criticized for its original experimental design and the general meaning of its results. But, all in all, it remains steadfastly rooted in the literature of educational psychology and provides a lasting contribution to the field.

I’m tired of talking. Let me explain. One of the basic rules of thumb for adult learning says that a class should be a little more than half practical application and workshop material to appeal to the audience. That aside, classroom (or instructor-lead) training has become expensive, and managers and consumers have become vocal in letting us know that they want to make sure it’s worth their time and money. To be plain, are we doing all we can to make the trip worthwhile?

I have always been an advocate for lots of hands-on activity in class, probably because it matches my own learning style but also because the majority of the attendees enjoy it. Not surprisingly, in the midst of teaching a class a few years ago, I started to wonder if I could get more time for discussion and activities, and lessen the burden we all felt in getting through the lecture pieces to the workshops. In this particular case the lecture was preparatory to the workshops and provided necessary background required to complete the labs and assignments. Fortunately, in addition to instructor-lead courses, I also work on web-based training and have done many voice over and narration tracks for online and computer-based presentations. Eureka! I found a way to off-load all the passive broadcasting of background material and recoup the time for projects, experiments, discussion and debate–the things that make class interesting and engaging. Although I didn’t have a name for it, I adopted the Inverted Classroom and have since learned that many others have had, either from desire or need, their own Eureka! experiences.

The “Inverted Classroom” as coined by professors Lage, Platt and Treglia in a paper presented to the Journal of Economic Education, Winter 2000, moves away from the traditional lecture. In it they describe how they saw a need to serve a wider variety of learning styles in class:

“Recent evidence has shown that a mismatch between an instructor’s teaching style and a student’s learning style can result in the student learning less and being less interested in the subject matter (Borg and Shapiro 1996; Ziegert forthcoming). This finding implies that either educational administrators should strive to ensure a good match between the instructor’s teaching style and the students’ learning styles (a difficult task) or that concerned instructors should use a portfolio of teaching styles so as to appeal to a variety of student learning types. Unfortunately, a majority of introductory economics courses are taught using only one teaching style–the traditional lecture format (Becker and Watts 1995).”

Lage, Platt and Treglia define the inverted classroom in simple terms:

“Inverting the classroom means that events that have traditionally taken place inside the classroom now take place outside the classroom and vice versa.”

What this means is that the class is designed in such a way that “passive” activities (such as listening to a lecture) are done outside class and what was lecture is replaced by workshops, discussion, and activities that require interaction. In theory this should increase the value of class time and provide more time for new and additional. Educators are still unsure how to optimize the inverted classroom, but what seems clear is that inverted classes will use of a mix of technologies like podcasts, DVDs, PowerPoint, text, video and interactive media in conjunction with hands-on projects and group activities.

Researchers Gerald C. Gannod, Janet E. Burge and Michael T. Helmick of Ohio’s Miami University are carrying out a study to evaluate the design and delivery of inverted classes in computer engineering. In a work-in-progress report delivered to the ASEE/IEEE Frontiers in Education Conference, 2007, Gannod states:

“Based on the SGID analysis performed on the course, student acceptance of the inverted classroom process has been well-received. Over eighty-five-percent of the students (in a class of twenty) have responded favorably to the inverted classroom structure, while over ninety-percent prefer the short learning activities over more prolonged assignments. In regards to the use of podcasting as a lecturing medium, students have indicated that the ability to use the play, pause, reverse, and fast-forward capabilities of the podcasted videos beneficial to their ability to learn the material.”

From the standpoint of instructor overhead, questions remain concerning the difficulty in designing, deploying and maintaining an inverted class. Certainly, the initial chore of creating podcasts (if they are used) may be considerable. Further, a sufficient number of high-quality projects and activities are required (vapid “busy work” may be less tolerated than boring lectures). Finally, the students must rise to the new class format and, to use an expression from the past, “come to class prepared.” Gannod plans to address issues of faculty overhead, podcast production and course maintenance in an upcoming report.

George Siemens at elearnspace mentioned a remarkable site called Indexed in a recent blog post. Indexed author Jessica Hagy uses mathematical metaphors in sketches of relationships that span topics from consumption and arrogance to expectations, communications and perception. Hagy claims in her About page that Indexed “… is a little project that allows me to make fun of some things and sense of others without resorting to doing actual math.” To be fair to all the mathphobes out there, the mathematics is rather mild and, more to the point, Hagy’s adept skill at using Venn diagrams and xy-graphs reminds me of what must be one of the primary objectives we all face when creating technical graphics:  transform complex observations and relationships into simple and appealing visual designs. A good graphic after all is a data compression scheme. It’s no wonder then that it’s often easier for many people to remember the graphic than the explanatory text.

I wonder if the relationship between confusion and information is really parabolic? Hmm….

In a note that could have been taken from one of Maria Montessori’s books, researchers in neuroscience, machine learning, education and psychology have convened to show that findings from a joint study suggest that “the prepared environment” might be supported by new scientific data.

“The ‘prepared environment‘ is Maria Montessori’s concept that the environment can be designed to facilitate maximum independent learning and exploration by the child.”

Terrence J. Sejnowski, Ph.D, researcher at the Computational Neurobiology Laboratory at the Salk Institute for Biological Studies and co-director of the Temporal Dynamics of Learning Center (TDLC) at the University of California, San Diego, echoes Montessori in his team’s findings. As quoted in Science Daily:

“To understand how children learn and improve our educational system, we need to understand what all of these fields [neurobiology, psychology, education, machine learning] can contribute. Our brains have evolved to learn and adapt to new environments; if we can create the right environment for a child, magic happens.”

The cross-disciplinary research points to a new science of learning that might influence the way classrooms are organized and run in the future. In particular, three guiding principles (or concurrent processes) emerge from the study:

1. Learning is computational
2. Learning is social
3. Learning is supported by neurological (perception-action) circuits

Research in machine learning and developmental psychology illuminate the computational complexity employed by learners who use statistical patterns and probabilistic models to infer rules of logic, relationships between words, syntax, and causal dependence between objects in the physical world.

Evidence that the three component processes happen concurrently is supported by the fact that learners do not calculate and compile statistical models of the environment indiscriminately but throttle the process using social cues from the people around them. Further, animal studies point to the presence of certain neurosteroids secreted during social interaction that promote learning.

Imitation also comes into play as a key factor:

“Imitation [presumably from others in the environment] accelerates learning and multiplies learning opportunities. It is faster than individual discovery and safer than trial-and-error learning.”

In essence, a social context fosters learning.

Brain circuits that support both actions and perceptions are directly involved with learning. As seen in language learning, for example, there is a complex mix of imitative, computational and articulatory processes that come into play as learning proceeds that might be further facilitated or enhanced at specific developmental periods. In general, neuroscientists have determined that there is considerable overlap in the systems brought into play during learning that support both perception and action. From Science:

“For example, in human adults there is neuronal activation when observing articulatory movements in the cortical areas responsible for producing those articulations. Social learning, imitation, and sensorimotor experience may initially generate, as well as modify and refine, shared neural circuitry for perception and action.”

Finally, experts in machine learning and artificial intelligence are taking advantage of the recent findings in social learning, computational modeling and the plasticity of the brain to design software that monitors and uses social cues and environmental factors to enhance learning. In the future this software may be used in tutorial programs or embedded in instructional robots that are specifically “tuned” to enhance teaching practices in classrooms.

New Science Of Learning Offers Preview Of Tomorrow’s Classroom

Foundations for a New Science of Learning

New science of learning offers preview of tomorrow

From baby scientists to a science of social learning

School is back in session and the Class of 2010 is on the home stretch towards graduation next spring. Given that many will no doubt move on to jobs in public and private enterprises,  corporate and government trainers and developers might want to peek around the corner to get a heads-up on some of the new students heading to class (virtual or otherwise) next year. The Beloit College Mindset List for the Class of 2010 has been published by Professors Ron Nief and  Tom McBride. In it are listed 75 identifying “experiences that have shaped the lives—and formed the mindset” of the Class of 2010. Thirty five are reproduced here. Perhaps telling more about the author than the Class of 2010, they are:

1. The Soviet Union has never existed and therefore is about as scary as the student union.

2. For most of their lives, major U.S. airlines have been bankrupt.

3. They have grown up getting lost in “big boxes.”

4. They have never heard anyone actually “ring it up” on a cash register.

14. Bar codes have always been on everything, from library cards and snail mail to retail items.

15. Carbon copies are oddities found in their grandparents’ attics.

16. Non-denominational mega-churches have always been the fastest growing religious organizations in the U.S.

17. They grew up in mini-vans.

18. Reality shows have always been on television.

19. They have rarely mailed anything using a stamp.

20. “So” as in “Sooooo New York,” has always been a drawn-out adjective modifying a proper noun, which in turn modifies something else

21. They have always been able to watch wars and revolutions live on television.

22. Ken Burns has always been producing very long documentaries on PBS.

23. Public school officials have always had the right to censor school newspapers.

24. Most of them never had the chance to eat bad airline food.

25. They have always been searching for “Waldo.”

26. They have always preferred going out in groups as opposed to dating.

27. They have always had access to their own credit cards.

28. They have never put their money in a “Savings & Loan.”

29. Bad behavior has always been getting captured on amateur videos.

30. Television stations have never concluded the broadcast day with the national anthem.

31. LoJack transmitters have always been finding lost cars.

32. Disposable contact lenses have always been available.

33. The U.S. has always been studying global warming to confirm its existence.

34. They grew up with virtual pets to feed, water, and play games with, lest they die.

35. Professional athletes have always competed in the Olympics.

Other lists for other years can be found here at the Mindset web site.

An NBC Nightly News report on the Beloit Mindset List can be viewed here.

Dean José Bowen of Southern Methodist University is not only advocating an outrageous pedagogical overhaul that many see as dangerous and ill-conceived, he is in the throes of implementing it as well. His professors at the Meadows School of the Arts are now required to teach primarily without computers or, more precisely, without PowerPoint slides. An short interview with Professor Bowen can be viewed here.

As reported in the Chronicle of Higher Education, Professor Bowen’s technological denuding of the classroom is motivated by several forces he sees eroding the quality of education in American classrooms:

• Lectures are boring and are usually done badly.
• PowerPoint is a terrible educational tool.
• Lectures are not interactive and can be done just as well online.

In Bowen’s impassioned view there is little reason for students to pay extra for the privilege of residential college tuition given the deplorable state of the antiquated lecture system. Bowen suggests that it can be done cheaper and perhaps better by the online colleges.  Secondly, students have the option of going to open courseware educational sites (like MIT and Stanford) to see lectures delivered in a way that are “really top notch.” In essence, as Bowen sees it, students will vote with their fingers as it were and take their lectures at a cheaper and better online resource if things do not change. “They will pay less for better.”

Bowen’s call to reform the lecture hall starts by asking what role the class meeting serves in light of modern media like podcasts and online presentations? His answer, make the lecture worth attending by using it as a venue for exploration of ideas, spontaneous questions and answers, group projects and debates. Use technology outside the classroom to prepare for the classroom.

Not surprisingly the Chronicle sites problems from both sides of the lecture hall:

“The biggest resistance to Mr. Bowen’s ideas has come from students, some of whom have groused about taking a more active role during those 50-minute class periods. The lecture model is pretty comfortable for both students and professors, after all, and so fundamental change may be even harder than it initially seems, whether or not laptops, iPods, or other cool gadgets are thrown into the mix.”

A previous foray into “inverting the classroom” at Miami University in Ohio evoked similar reactions from the students:

“‘Initial response is generally negative until students start to understand and see how they learn under this new system,’ says Glenn Platt, a professor of marketing at Miami who has published academic papers about the approach, which he calls the ‘inverted classroom.”’The first response from students is typically, ‘I paid for a college education and you’re not going to lecture?””

Both Bowen’s and Platt’s views converge on one nagging conclusion: We have to create good reasons for students to come to lectures. If not they will tune out, turn off, and probably go elsewhere. It seems ironic that in an age of mobile computing, electronic media and information at the speed of light that the lecture hall may only survive if it returns as a low-tech 21st Century edition of the classical academy. Time will tell which particular approaches favor this revitalization of the classroom but it is hard to deny that it is desperately needed.

Teach Naked: Dean Urges Tech-Free Classes (NPR)

Teaching Naked: Why Removing Technology from your Classroom Will Improve Student Learning

In an article that reads surprisingly like a case study from a course on McLuhans’ Laws of Media, T. X. Hammes writes in the Armed Forces Journal on the pernicious effects of pushing PowerPoint too far in the presentation culture of the Pentagon. Apparently keenly aware of the implicit bias of media, Hammes observes:

“Every year, the services spend millions of dollars teaching our people how to think. We invest in everything from war colleges to noncommissioned officer schools. Our senior schools in particular expose our leaders to broad issues and historical insights in an attempt to expose the complex and interactive nature of many of the decisions they will make.

Unfortunately, as soon as they graduate, our people return to a world driven by a tool that is the antithesis of thinking: PowerPoint. Make no mistake, PowerPoint is not a neutral tool — it is actively hostile to thoughtful decision-making. It has fundamentally changed our culture by altering the expectations of who makes decisions, what decisions they make and how they make them. While this may seem to be a sweeping generalization, I think a brief examination of the impact of PowerPoint will support this statement.”

Others have voiced concern over the nature and limitations of this tool and its ilk. Edward Tufte for example penned the monograph “The Cognitive Style of PowerPoint: Pitching Out Corrupts Within” in an attempt to illustrate the common problems with the medium and offer suggestions on how to rectify them. Designers, illustrators and even cognitive scientists join the chorus in an effort to stem the plague of needlessly ineffective slide shows.

PowerPoint and its cousins have their genetic roots in presentation packages designed for selling, which is why PowerPoint still has a strong tendency to reduce everything it touches to a sales pitch. Hammes lights on this when he mentions how language and communication are bent to that of the Ad Man:

“Let’s start by examining the impact on staff work. Rather than the intellectually demanding work of condensing a complex issue to two pages of clear text, the staff instead works to create 20 to 60 slides. Time is wasted on which pictures to put on the slides, how to build complex illustrations and what bullets should be included. I have even heard conversations about what font to use and what colors. Most damaging is the reduction of complex issues to bullet points. Obviously, bullets are not the same as complete sentences, which require developing coherent thoughts. Instead of forcing officers to learn the art of summarizing complex issues into coherent arguments, staff work now places a premium on slide building. Slide-ology has become an art in itself, while thinking is often relegated to producing bullets.”

In PowerPoint language is reduced to a staccato burst of one-liners. Complete sentences are not at home in the medium. Language and rhetoric are reduced to a fractured mosaic of bullets, images and partial thoughts that serve as placeholders for information and ideas. The inherent bandwidth limitation of the medium is fine for sales presentations but falls flat when content and depth are required. Users struggle, perhaps unknowingly, to compensate for the inherent bias of the medium:

“Our personnel clearly understand the lack of clarity and depth inherent in the half-formed thoughts of the bullet format. In an apparent effort to overcome the obvious deficiency of bullets, some briefers put entire paragraphs on each briefing slide. (Of course, they still include the bullet point in front of each paragraph.) Some briefs consist of a series of slides with paragraphs on them. In short, people are attempting to provide the audience with complete, coherent thoughts while adhering to the PowerPoint format. While writing full paragraphs does force the briefer to think through his position more clearly, this effort is doomed to failure.”

Compounding the problem, (post-literate) reading speeds and the need to digest detailed and complex data fly in the face of the easy sales pitch proffered by the slide deck:

“People need time to think about, even perhaps reread, material about complex issues. Instead, they are under pressure to finish reading the slides before the boss apparently does. Compounding the problem, the briefer often reads these slides aloud while the audience is trying to read the other information on the slide. Since most people read at least twice as fast as most people can talk, he is wasting half of his listeners’ time and simultaneously reducing comprehension of the material. The alternative, letting the audience read the slide themselves, is also ineffective. Instead of reading for comprehension, everyone races through the slide to be sure they are finished before the senior person at the brief. Thus even presenting full paragraphs on each slide cannot overcome the fundamental weakness of PowerPoint as a tool for presenting complex issues.”

Hammes notes other signs of users’ struggle against the flow of the medium in mentioning the “quad chart” and slides crammed with so much information they cannot be processed by the viewer’s visual system, let alone addressed by the speaker. This is simply a low-bandwidth medium with rigid boundaries.

An Example Quad Chart

“The next major impact of slide-ology has been the pernicious growth in the amount of information portrayed on each slide. A friend with multiple tours in the Pentagon said a good rule of thumb in preparing a brief is to assume one slide per minute of briefing. Surprisingly, it seems to be true. Yet, even before the onslaught of the dreaded quad chart, I saw slides with up to 90 pieces of information. Presumably, some thought went into the bullets, charts, pictures and emblems portrayed on that slide, yet the vast majority of the information was completely wasted. The briefer never spoke about most of the information, and the slide was on screen for a little more than a minute. While this slide was an aberration, charts with 20 items of information portrayed in complex graphics are all too common. This gives the audience an average of three seconds to see and absorb each item of information. As if this weren’t sufficient to block the transfer of information, some PowerPoint Ranger invented quad charts. For those unfamiliar with a quad chart, it is simply a Power Point slide divided into four equal quadrants and then a full slide is placed in each quadrant. If the briefer clicks on any of the four slides, it can become a full-sized slide. Why this is a good idea escapes me.”

Hammes further notes that PowerPoint, like every technology, creates or alters the environment of the user. Interestingly, Hammes cites the effect PowerPoint has on time and events:

“PowerPoint has clearly decreased the quality of the information provided to the decision-maker, but the damage doesn’t end there. It has also changed the culture of decision-making. In my experience, pre-PowerPoint staffs prepared two to four decision papers a day because that’s as many as most bosses would accept. These would be prepared and sent home with the decision-maker and each staff member that would participate in the subsequent discussion. Because of the tempo, most decision-makers did not take on more than three or four a day simply because of the requirement to read, absorb, think about and then be prepared to discuss the issue the following day. As an added benefit for most important decisions, they ’slept on it.’

PowerPoint has changed that. Key decision-makers’ days are now broken down into one-hour and even 30-minute segments that are allocated for briefs. Of particular concern, many of these briefs are decision briefs. Thus senior decision-makers are making more decisions with less preparation and less time for thought. Why we press for quick decisions when those decisions will take weeks or even months to simply work their way through the bureaucracy at the top puzzles me.”

Hammes does not miss the effect the indiscriminate use of the tool has on understanding and thought processes (”We shape our tools and then our tools shape us.” – McLuhan):

“Unfortunately, by using PowerPoint inappropriately, we have created a thought process centered on bullets and complex charts. This has a number of impacts. First, it reduces clarity since a bullet is essentially an outline for a sentence and a series of bullets outline a paragraph. They fail to provide the details essential to understanding the ideas being expressed. While this helps immensely with compromise, since the readers can create their own narrative paragraphs from the bullets, it creates problems when people discover what they agreed to is not what they thought they had agreed to. Worse, it creates a belief that complex issues can, and should, be reduced to bullets. It has reached the point where some decision-makers actually refuse to read a two-page briefing paper and instead insist PowerPoint be used.”

In closing Hammes concedes that there are appropriate uses for PowerPoint but these tend to be presentations that are closer to its origin: “primarily, information briefs rather than decision briefs.” As depth and complexity increase, the appropriateness of PowerPoint falls away. As Hammes says, “There is a reason students cannot submit a thesis in PowerPoint format.”

In addition to being a Nobel Laureate (1965), great story teller, and perhaps the most passionate and unrelenting student of physics in the 20th century, Richard Feynman (1918-1988) was also one of the greatest contemporary teachers of physics. His Feynman Lectures are no less than a gold standard in science education and still inspire and inform students more than 40 years after they were first given. Many professional physicists I have known (perhaps secretly) refer to his Lectures on Physics whenever they need a quick “refresher” on a topic or a summary of a long-forgotten area well beyond their specialty. Feynman was quirky, unique, eccentric, out-spoken, always informative, and always in command of his subject. He did not respect self aggrandizing appearances or mimetic behavior and showed this in an address he gave in 1974 at a commencement ceremony at CalTech, now recorded in essay form here and here.

In Cargo Cult Science Feynman lights on several pseudo-scientific pursuits that cause him concern: ESP, metal bending, mystical states, reflexology, and yes, education. An acknowledged master at both physics research and education, he says:

“A teacher who has some good idea of how to teach her children to read is forced by the school system to do it some other way—or is even fooled by the school system into thinking that her method is not necessarily a good one. …So we really ought to look into theories that don’t work, and science that isn’t science.”

Feynman had a clear view of what was scientific, that is, what followed the scientific method and produced testable laws. Education did not, in Feynman’s mind, qualify as Science but was relegated to Cargo Cult Science – a mimetic form that played at being scientific but didn’t deliver the goods.

From the talk:

“I think the educational and psychological studies I mentioned are examples of what I would like to call cargo cult science. In the South Seas there is a cargo cult of people. During the war they saw airplanes land with lots of good materials, and they want the same thing to happen now. So they’ve arranged to imitate things like runways, to put fires along the sides of the runways, to make a wooden hut for a man to sit in, with two wooden pieces on his head like headphones and bars of bamboo sticking out like antennas—he’s the controller—and they wait for the airplanes to land. They’re doing everything right. The form is perfect. It looks exactly the way it looked before. But it doesn’t work. No airplanes land. So I call these things cargo cult science, because they follow all the apparent precepts and forms of scientific investigation, but they’re missing something essential, because the planes don’t land.

Now it behooves me, of course, to tell you what they’re missing. But it would be just about as difficult to explain to the South Sea Islanders how they have to arrange things so that they get some wealth in their system. It is not something simple like telling them how to improve the shapes of the earphones. But there is one feature I notice that is generally missing in cargo cult science. That is the idea that we all hope you have learned in studying science in school—we never explicitly say what this is, but just hope that you catch on by all the examples of scientific investigation. It is interesting, therefore, to bring it out now and speak of it explicitly. It’s a kind of scientific integrity, a principle of scientific thought that corresponds to a kind of utter honesty—a kind of leaning over backwards. For example, if you’re doing an experiment, you should report everything that you think might make it invalid—not only what you think is right about it: other causes that could possibly explain your results; and things you thought of that you’ve eliminated by some other experiment, and how they worked—to make sure the other fellow can tell they have been eliminated.”

Feynman was not antagonistic towards the arts, he just didn’t think that a theory in a social science, for example, was equivalent to that in a physical science:

“But then I began to think, what else is there that we believe? (And I thought then about the witch doctors, and how easy it would have been to check on them by noticing that nothing really worked.) So I found things that even more people believe, such as that we have some knowledge of how to educate. There are big schools of reading methods and mathematics methods, and so forth, but if you notice, you’ll see the reading scores keep going down—or hardly going up in spite of the fact that we continually use these same people to improve the methods. There’s a witch doctor remedy that doesn’t work. It ought to be looked into; how do they know that their method should work?”

More to the point, these “theories” can intimidate and confuse, and often don’t go much farther than advertisements in their ability to inform:

“The easiest way to explain this idea is to contrast it, for example, with advertising. Last night I heard that Wesson oil doesn’t soak through food. Well, that’s true. It’s not dishonest; but the thing I’m talking about is not just a matter of not being dishonest, it’s a matter of scientific integrity, which is another level. The fact that should be added to that advertising statement is that no oils soak through food, if operated at a certain temperature. If operated at another temperature, they all will— including Wesson oil. So it’s the implication which has been conveyed, not the fact, which is true, and the difference is what we have to deal with.”

The bottom line is honesty, integrity and awareness. Education, technical training, instructional design, and plain old teaching are complex fusions of art and science. They are complicated endeavors for which we have yet to figure out the laws. As Feynman would say, it’s like we are learning the laws of chess by watching games being played, and gradually deduce that certain pieces remain on the same color square and that certain odd behaviors between pieces (like castling) can occur in a corner of the board. Being unscientific doesn’t necessarily make an endeavor worthless, undesirable or even ineffective, but it does behoove us to be clear about its character. It’s important to be honest about the level of our understanding and know the limits of the technologies we employ, be they educational theories, pet approaches in the classroom, or PowerPoint.

Julie Evans of Project Tomorrow delivered a talk at The Future of Education web site on the findings of Speak Up, an annual national research project sponsored by her organization. Titled Top Ten Things We Learned from K-12 Students About Educational Technology in 2008, the report is a real eye-opener and should be of great interest not only to high school and college instructors but also corporate, government and military trainers who need to prepare for the educational tsunami that is forming. A table of findings from the survey are presented below. Many of the issues reported in the summary are already being seen in adult training venues. Others, no doubt, are just over the horizon and will certainly become standard topics of sundry research reports, conference talks, and blogs like this in the near future.

iPods in School - Here They Come, Ready or Not!

Although there has been a notion floating around for several years that iPods can be used effectively as instructional tools, psychologists at SUNY Fredonia have only recently completed a study to quantify the value of the iPod in a lecture course. Professors Dani McKinney, Jennifer Dyck, and student Elise Luber (’08) have compared the effectiveness of podcasts to live lectures.

McKinney et al. divided a group of 64 students into two groups, one of which received a podcast lecture complete with podcast-formatted slides and printed hand-outs of the instructor’s presentation. The control group received the same hand-outs but attended the lecture. Test results indicate that the podcast group did considerably better than the live lecture group, especially if they treated the podcast as a live lecture.

“The podcast group averaged nine points (out of 100) higher on the test than those in the live audience. Moreover, those who took notes during the podcast scored even higher, averaging 15 points higher than their live-lecture counterparts.”

Commenting on the results, McKinney explains:

“If they listened to the podcast just one time, they didn’t do any better than the people who came to the lecture. However, the people who treated it like a live lecture, and took notes or replayed certain sections… they did significantly better.”

The research suggests that active involvement with the podcast combined with taking advantage of the inherent properties of the technology paid off. According to McKinney:

“If you treated it like a live lecture, you did better. But if you just listened to it passively, you didn’t get any benefit. One student watched the podcast at the gym, and his score reflected that. One person watched the podcast seven times, and her score reflected that.”

McKinney is quick to point out that this study is preliminary and hardly conclusive. She plans to extend the study to other subjects like biology, chemistry, sociology and history. A one semester study is also planned to assess the effect of longer time frames on the effectiveness of the iPod as an educational technology.

Although few educators believe the podcast is radically different from earlier approaches that used recording technology such as audio cassettes, McKinney does believe there is a general lesson to be gleaned for the study:

“Learning doesn’t change, regardless of the medium.” If you want to perform well on exams, you need to leave yourself usable ‘breadcrumbs,’ visual and mental cues. Study, take notes, listen and take more notes. That’s how you learn, regardless of whether you’re watching a professor in a class or an iPod in your hand.”

Teaching College Courses Online vs Face-to-Face

A recent report by the US Department of Education will no doubt add fuel to an already raging debate over the virtues and deficiencies of online education. Evaluation of Evidence-Based Practices in Online Learning – A Meta-Analysis and Review of Online Learning Studies provides an extensive meta-analysis of data that compare the effectiveness of online versus traditional classroom approaches to instruction.

Designed to review over 1,000 empirical studies published from 1996 to 2008, the report focuses on studies that:

(a) contrasted an online to a face-to-face condition,

(b) measured student learning outcomes,

(c) used a rigorous research design, and

(d) provided adequate information to calculate an effect size.

The meta-analysis echoes results reported earlier, namely,

“… on average, students in online learning conditions performed better than those receiving face-to-face instruction.”

The authors of the report explain their findings by noting that:

“The difference between student outcomes for online and face-to-face classes—measured as the difference between treatment and control means, divided by the pooled standard deviation—was larger in those studies contrasting conditions that blended elements of online and face-to-face instruction with conditions taught entirely face-to-face. Analysts noted that these blended conditions often included additional learning time and instructional elements not received by students in control conditions. This finding suggests that the positive effects associated with blended learning should not be attributed to the media, per se.”

A paucity of data for K-12 is noted in the findings, leading the authors to caution readers about generalizing the results to that population.
