No pain, more gain? Research supports "less learning more often"

Memes, genes and by Jove, the future of learning
Dutch biologist Gerard Jagers op Akkerhuis from Radboud University Nijmegen predicts that the next the next step in evolution will lead to a life form in which the transfer of the blueprint by means of genes is replaced with the transfer of knowledge and collective experience by so-called ‘memes’.
In Jagers’ view:
Memes are codes that determine the structure of the brain. In turn, the structure of the brain determines someone’s knowledge. In this way, memes are carriers of brain structure and the corresponding knowledge, just like genes are carriers of protein recipes and the corresponding cell physiology.
The next life form will not necessarily develop by means of biological evolution: as far as Jagers is concerned, a machine that shows intelligent behaviour based on a neural network fulfils the definition of life. If this system can then also pass on its memory to the next generation then this involves a new step in evolution.
Consider this alongside some of the recent genetic research that is uncovering the influences on our ability as organic beings to learn more effectively. For instance, this recent report on the RGS14 gene. Apparently, switching off this single gene in mice unlocks a part of their brain that is otherwise inactive, boosting learning and memory.
Other research reports on how increasing the production of this same gene can dramatically improve visual memory. In experiments, mice could remember objects they had seen for up to two months - ordinarily the same mice would only be able to remember these objects for about an hour. Clearly, it remains to be seen if the same effects are achieved in humans, but the indications are positive.
By Jove - what are the implications?
The implications of both these developments suggest we are entering a new era of dramatically accelerated learning that is likely to be boosted by both our interventions at the genetic and pharmaceutical level, as well as our application of technology. Where these converge nicely is in a site called Jove. As the site defines itself:
The Journal of Visualized Experiments (JoVE) was established as a new tool in life science publication and communication, with participation of scientists from leading research institutions. JoVE takes advantage of video technology to capture and transmit the multiple facets and intricacies of life science research. Visualization greatly facilitates the understanding and efficient reproduction of both basic and complex experimental techniques, thereby addressing two of the biggest challenges faced by today’s life science research community: i) low transparency and poor reproducibility of biological experiments and ii) time and labor-intensive nature of learning new experimental techniques.
This is a fantastic resource which is dramatically accelerating knowledge transfer within the scientific community. Now imagine this happening in all other knowledge domains. TED is a major catalyst in its own right (I have an article coming out that discusses this next week) and I am sure others exist already in many other fields - let me know if you know of any so I can compile a list.
Thinking about Jagers proposition further, our methods for storing and sharing knowledge and skills online using ever more sophisticated cloud-based tools surely is leading us towards on a deeper dependence on technology to pass on our memories to future generations. The recent bleating about how technology threatens our children minds (Greenfield again) misses the point - the horse has bolted and frankly is evolving rapidly into a far faster animal that we cannot yet recognise.

Coffee fuelled brains – explains media hyperbole?
A new study published today suggests that drinking five cups of coffee a day could reverse memory problems seen in Alzheimer's disease. But actually it doesn’t. The article on the BBC website goes on to report:
"This research in mice suggests that coffee may actually reverse some element of memory impairment.
"However much more research is needed to determine whether drinking coffee has the same impact in people.
"It is too soon to say whether a cup of coffee is anything more than a pleasant pick me up."
So the effect of this reportage is misleading. The headline is memorable (“Coffee ‘may reverse Alzheimer’s’”) which is at odds with the detail at the end of article. The behavioural take away is more than likely “I know, I’ll make sure I drink more coffee” legitimising an existing habit based on largely unproven evidence. At least this report nullified itself in one place, rather than selectively quoting from a study to support its own baseless argument.
I’m picking on coffee in this instance, but this is just one of many examples where the media report on research studies exaggerating the conclusions and leading with speculation.
That said, there are exciting developments in the field of neuroscience and our understanding of brain chemistry that should lead to genuine treatments and supplements that support memory and improve our capacity to learn faster and perform more effectively.
A diet of HDL cholesterol, blueberries and coffee may be part of the answer. But beware you don’t still end up doing stupid things albeit faster and with more energy.

The Evidence on Online Education
The study found that students who took all or part of their instruction online performed better, on average, than those taking the same course through face-to-face instruction. Further, those who took "blended" courses -- those that combine elements of online learning and face-to-face instruction -- appeared to do best of all.
The US Department of Education noted that this new meta-analysis differs from previous such studies, which generally found that online education and face-to-face instruction were similarly effective on issues of learning, but didn't give an edge to online learning that may now exist.
While the new study provides a strong endorsement of online learning, it also notes findings about the relative success (or lack thereof) of various teaching techniques used in online courses. The use of video or online quizzes -- frequently encouraged for online education -- "does not appear to enhance learning," the report says.
That is something to think about - I wonder what the quality of these video and quizzes were like?
Using technology to give students "control of their interactions" has a positive effect on student learning, however. "Studies indicate that manipulations that trigger learner activity or learner reflection and self-monitoring of understanding are effective when students pursue online learning as individuals," the report says.
Notably, the report attributes much of the success in learning online (blended or entirely) not to technology but to time. "Studies in which learners in the online condition spent more time on task than students in the face-to-face condition found a greater benefit for online learning," the report says.
That's an interesting statement - taking the time to learn is a critical factor, which is a clearly central to genuine self reflection and ensuring understanding. Having control over that time is crucial too. Many classroom situations are not conducive to this at all. So your learning environment is critical. Actual learning time in these situations may be minimal compared to the more effective time spent learning in a more concentrated, but spaced fashion (or virtually collaborating) online. This supports my own cry for less learning, more often.
Accountability and orientation
Here's a great comment on this report from "SL" who appears to be at the front line in offering students online learning opportunities and tells it like it is - give the right motivational support and guidance on online learning tools and students will respond positively:
Yes, I may have to spend a little extra time at the beginning of the term making sure my students understand how to navigate the LMS and point them to the online course resources, activities and communications tools, but they don't get the option of NOT learning how to use them, even in my F2F classes, which I would term all blended to a great er or lesser degree! In some EVERYTHING for the course is in our LMS and it is taught in a computer classroom.
The results are always the same:
1) An early steep learning curve, with a fair amount of "I can't" and "You're making us do all the work!" whining.
2) A period of "Well yeah, maybe I can" when a lot of the tech-forward students start helping their tech-phobic classmates (with my encouragement because I am into the subject matter content phase at that point(although I will always help students one on one with tech issues outside of class) which fosters group interaction and interdependence.
3)What I like to call "the quiet time" from about three weeks into the term until near the end, when my blended courses are firing on all cylinders (meaning the students have finally accepted that I am NOT going to do this for them- it is up to THEM, individually and collectively), right through me attending meetings, "lost" class time from snow days, athletics trips (all our teams travel with a laptop), students having to go home for family or health emergencies (including one having to miss the last month of a term for major surgery), etc. My "class" is always in session, 24-7, rain or shine, internet-willing. "All" I have to do during this period is put out tech brush-fires (people suddenly locked out of their account, etc) and serve as guide on the side, spending parts of each class meeting as a "cheerleader", answering questions,doing demonstrations, reviewing 3D models (often in a "game" format), giving new topic overviews,leading (or just listening to) discussions, advising on group projects, and of course my "real job":, assessing learning (A LOT) with regular online quizzes and exams. A fair amount of classtime is "free" for them to work, alone or together, on class assignments and online learning activities. Then all I do is walk around to keep them on task and off Facebook.
4) And lastly, what I term the celebratory "We did it!!!" phase, when the students look up, realize the term is almost over and that they have accomplished a BUTTLOAD of work and learned a great deal and that they did it (mostly) all THEMSELVES. Sometimes they do accuse me of having "tricked them into learning stuff". For that I do not apologize!? ;-) >95% excellent course evaluations ensue, students ask what other courses I teach the same way and sign up for "extra" courses in my discipline, tests of retention in later classes and our program assessments show great retention for my blended students, and the students beg other faculty to use the LMS for course materials, the calendar, etc. and sometimes even show them how to do so. Students come back and report that the class made them a better, more responsible student in other classes, regardless of delivery method.
And no, these are not upper level or grad courses (which actually turn out to be a bit more comfortable taught in a more traditional Socratic style) however in those we still use the LMS for all sorts of course material exchange and communication. Its just a great way to put everything in one place, for faculty and students alike! The courses I teach as most strongly blended are a freshman-level non-majors class and a 200-level service course.
You just have to get past that Phase 1 with a determined and positive "Yes you CAN!" attitude ...
We need more people in education like this. What a difference that would make...

Stress and memory

Stress can be both negative and positive in affecting our performance. Interestingly, many training experiences lack any element of stress and as such can be unstimulating and unrepresentative of the real environment.
This study however focuses on the negative impact stress has on forming context dependent memories.
We exposed healthy adults to stress or a control procedure before they learned an object-location task in a room scented with vanilla. Memory was tested 24 h later, either in the same or in a different context (unfamiliar room without the odor). Stress administered prior to encoding abolished the context-dependent memory enhancement found in the control group.
This feels like another example of cognitive load being overwhelmed by an overstimulating (stressful) environment. By overwhelming our short term memory faculties, we cannot embed meaningful memories as effectively.
In my previous post, I wrote about how doodling is a positive response to an unstimulating (boring) environment which can enhance memory recall. It seems to me that a successful learning experience balances a realistic representation of the actual environment where new skills and knowledge need to be applied, alongside time for creative reflection. How often does that happen?

Research merry-go-round up
I've been sitting on a number of research/news snippets which are all interesting but demonstrate how fluid the respective fields of neuroscience, cognitive psychology and educational study are. Sometimes it's hard to draw immediately practical inferences. Things are moving so fast that you can move from positions of contradiction, congruence and back to contradiction in a matter of days. This can be confusing, especially when you throw in the usual journalist demand for a sensationalist angle.
These recent headlines are a case in point:
Brain training claims dismissed
A Which? report states the obvious around some popular brain training software such as those from Nintendo, Lumosity and Mindweavers. It's still too early for anyone to claim categorically that their tools can, in isolation, lead to improved cognitive function. Other environmental factors always play a key role, which makes conclusive studies difficult.
Knitting can delay memory loss
A US study supports engaging in a hobby prevents memory problems later in life (by 40%). Keeping physically and mentally active is the key message - again stating the obvious perhaps?
Texting improves language skills
A positive report that "textisms" could be having a beneficial effect on reading development. Also the University of Toronto found instant messaging had a positive effect on teenagers' command of language.
Social websites: bad for kids' brains?
A number of reports alleging that online networking and gaming have health risks. Susan Greenfield weighs in on the debate stating that young brains may be fundamentally altered by internet activity - which is again fairly obvious. Why just young brains? Old brains are (almost) just as plastic. For more on this, Donald Clark does a great job of putting her expert opinion under critical review.
Digging deeper
With all this potential for confusion I find it's important to trace things back to their sources where-ever possible as there are usually more solid nuggets of information to be found. I'll leave you with one interesting piece on a subject I've posted on before - memory and sleep. In this study, it has been found that stages of sleep have distinct influence on the process of learning and memory. Communication between the hippocampus and prefrontal cortex appears to change when moving between SWS and REM sleep. When disconnected (as it is during REM sleep) you are more likely to forget newly formed memories, explaining perhaps why most dreams are forgotten.

Think Gum - chew and remember
Think Gum aims to:
...take advantage of proven brain-boosting herbs and herbal extracts, potent antioxidants, the principles of aromatherapy, the stimulant qualities of naturally occurring caffeine, breakthroughs in memory research, and the physical properties of chewing gum itself. In short, Think Gum enhances mental performance.
Not sure of the claims but besides the impact of brain chemistry on cognitive processes, it does highlight the importance of context in learning. The environment - taste and smell included - plays a significant role in recalling memories:
If test takers chew Think Gum while learning, their recall of such information will be better when they chew Think Gum again.
Not sure what happens when you get through all the distinctive flavours they offer, but these are interesting studies quoted on the site:
(1) Herz RS. The effects of cue distinctiveness on odor-based context-dependent memory. Mem Cognit. 1997 May;25(3):375-80.
(2)Pointer SC, Bond NW. Context-dependent memory: colour versus odour. Chem Senses. 1998 Jun;23(3):359-62.
(3)Morgan CL. Odors as cues for the recall of words unrelated to odor. Percept Mot Skills. 1996 Dec;83(3 Pt 2):1227-34.
(4)Smith DG, Standing L, de Man A. Verbal memory elicited by ambient odor. Percept Mot Skills. 1992 Apr;74(2):339-43.
Scratch and sniff test papers can only be a short time a way...
If anyone has had a try of this stuff I'd be interested to know if you felt any positive effects.

Memory research roundup - Sleep
Here's yet another study supporting the need for sleep to consolidate a new experience.
To sleep, perchance to remember
(Nice title, not mine but a similar Shakespearian steal as Learning As You Like It)
Neuroscientists at Geneva University have discovered that sleep can produce a lasting impact on how the brain processes and stores newly learnt information. The research, conducted by Sophie Schwartz of the Neurology and Imaging of Cognition laboratory at Geneva University, involved subjects being exposed to new visual stimuli, such as a face or tasks like tracing a moving dot with a joystick. They were then allowed to sleep normally - or not.
Scientists compared a whole night of normal sleep with a whole night of sleep deprivation, naps versus no naps, and eight hours of night sleep compared with eight hours of being awake during the day. The brain changes were highly localised and relevant to the task the volunteer had been set.
Brain scans of humans and animals have indicated that bursts of information pass between the neocortex and the hippocampus during the first hours of sleep, known as slow wave sleep. It is during slow wave sleep that the brain remembers declarative or episodic memory – precise facts a person can access consciously. Our skills – or procedural memory – are encoded during the rapid eye movement sleep, which is more abundant during the latter hours of the night.
Right, I'd better get off to bed myself now for a bit of my own consolidation...

Memory research roundup - Blueberries
Scientists Find Blueberries Reverse Age Related Memory Deficits
Researchers (from the Schools of Food Biosciences and Psychology in Reading and the Institute of Biomedical and Clinical Sciences at the Peninsula Medical School in Exeter) supplemented a regular diet with blueberries over a three month period. Within three weeks, they discovered improvements in spatial working tasks and the improvements continued throughout the course of the study.
The enhancement of both short-term and long-term memory is controlled in neurons (brain cells) at the molecular level. The researchers think flavonoids found in blueberries may help learning and memory by enhancing existing neuronal connections, improving communication between cells and stimulating the regeneration of neurons.
The scientists were able to pinpoint the ability of flavonoids to activate signaling proteins in a specific area of the hippocampus, the learning and memory-controlling part of the brain.

Memory research round up - Cholesterol
Over the next few posts I'll summarise the ones that most caught my eye:
Cholesterol and Memory
People with high levels of cholesterol of the HDL variety (high-density lipoprotein) did better on memory tests than those with lower levels. The UK research checked the levels of 3,600 British civil servants and gave them memory tests at an average age of 55 and then again at 61. The tests involved reading a list of 20 words and then asked to write down as many as they could remember within 2 minutes (I'm guessing they didn't use Brain Training on the Nintendo DS for this task).
Apparently, not only did those with higher HDL do better, but those whose HDL levels declined between tests also saw a decline in their performance.
This research is part of a long term "Whitehall II" study that started in 1985 and has been following over 10,000 male and female London-based members of the British Civil Service. The participants have regular clinical exams and periodically fill in questionnaires.

Movement and Memory
Well I'm back from vacation in sunny southern Spain. The majority of time was spent relaxing, gazing at the view above, a bit of swimming, reading and generally moving as little as possible. One day, my son Gus (aged nine) and I (a lot older) decided that the mountain needed climbing. So we did. Took us seven hours and required lots of moving...up and down rocky trails mainly. We were fortunate to bump into Ibex, numerous lizards of various sizes and shapes, and thousands of butterflies and, on arriving at the top, were rewarded with some tremendous views across the Spanish coast and even out to North Africa. We had a great day - it was hard work at times but were left with a real sense of achievement (especially for Gus as that was his first proper mountain). We will recall many memories of that journey for years to come.
So it was particularly resonant for Cognitive Daily to re-post an article citing how body position affects the memory of events.
According to the study:
Holding your body in the right position means you'll have faster, more accurate access to certain memories. If you stand as if holding a golf club, you're quicker to remember an event that happened while you were golfing than if you position your body in a non-golfing pose.
Regardless of their age, the study volunteers' memories were reported significantly sooner when the volunteers' body position matched the memory being asked for.
Dijkstra's team believes that the effect may be due to the way memories are stored in the brain: one theory of memory suggests that memories are composed of linked sensory fragments -- odors, sights, sounds, and even body positions. Simply activating one or more of those fragments makes the entire memory more likely to be retrieved. In any case, if you're trying to recall a particular incident in your life, putting your body in the right position might help you remember it faster and more accurately. The key appears to be your body position when the memory occurred.
The implications for effective learning transfer are significant. To speed memory recall the learning event should closely mimic the context and physicality of the environment in which that learning is put into actual practice. Learning through doing, that closely simulates a real situation means that the experience gained (the memory of the practice) can be readily and meaningfully recalled when a similar situation occurs.
It follows that the multisensory experience of games and virtual simulation are much more likely to achieve meaningfull recall if you are free to move about in the way that mimics the "real" environment you will perform these skills in. So until the Wii came along, sitting still in front of screen, in a largely sedentary and still position is not congruent with achieving effective recall of practice memories to use in real world situations. The military, aerospace and the world of sport all know the value of consistent, spaced, repetitive practice that closely simulates the real often highly stressful (and in some cases life threatening) situations in which they need perform.
A lot of face to face training and e-learning fails to take this into consideration. But that will change as we become less and less bound by walls and desktop PCs and become fully mobile learners. It will be intriguing to see how we then design learning experiences that effectively align our physical and cognitive performance.
Wii Fit may be leading the way...

Gaming Kids More Social, Not Less
It's SATs time in the UK for primary school kids and I'm sitting writing this post while Question Time is discussing the value of testing kids at the age of 11 in this way (my own daughter being one of them). The emphasis on testing in artificial environments that are abstracted from a real world context seems to create a lot of heated debate. The issue of stress and pressure placed on kids to perform appears to be of high concern.
At the same time, there is the usual fuss over the latest Grand Theft Auto release and how it legitimises violent and illegal behaviour (despite most people missing the level of irony and sophistication of interactive narrative the game employs).
So it's intriguing to read a research study from University of California, Davis that finds the following:
"There is a lot of hemming and hawing among educators about the introduction of technology in the early grades," said Cynthia Carter Ching, associate professor of education at the University of California, Davis. "But the worst-case scenarios just don't pan out. Technology can facilitate creativity and social awareness, even when we don't design the use of it to do so. And when we do design technology activities with these things in mind, the possibilities are endless."
In two recent studies of kindergarten and first-grade students, Ching observed that children find ways to transform their experiences with technology into fun, highly organized group activities. She also found that technology-based activities can be explicitly designed to foster social reflection and advanced planning among young children.
In their first study, Ching and Wang observed children who chose to play a computer game during their free time. Though only one child could play at a time, the children negotiated turns and gave each other advice about how to play the game."Though this is hardly the ideal setting for social interaction and higher-level thinking, the children exhibited a great deal of executive planning skills and complex social negotiations without any guidance or interference from adults," Ching said.
In the second study, children were given digital cameras and told to create digital photo journals. The students displayed creativity and engaged in complex planning at every stage of the assignment, from how they framed their shots to how they chose to organize them to tell a story, Ching found."This study shows that rather than technology being something that children merely use, it can be a creative tool for increased reflection on social networks, friendships, relationships with teachers and a sense of self within the world of school," Ching said.
These findings seem to sit well with Sugata Mitra, Professor of Educational Technology at Newcastle University's findings from his Hole in the Wall experiments (see my Learning as you like it article). By literally building a networked PC into a wall accessible in an outside space (very much like a cash machine here), and providing no direction or instruction he sat and waited to watch what would happen. One child learned to browse in 6 minutes and was teaching 70 other children by the end of the day. They interacted with content that was not even in their own language – they had to self-learn English to get to the content itself. In one experiment children managed to grasp basic concepts of biotechnology and the principles of DNA! All this occurred without a teacher or classroom.
So imagine a world where SATs were not old school exams that stress and, arguably, reveal little about actual learning, and instead were embodied in one big social, highly collaborative game environment that kids where naturally motivated to play as individuals and in teams. In the process they would demonstrate the learning and cognitive performance we are looking for. The metrics we could get from such an environment would help deliver personalised coaching and tuition for each child.
A misguided fantasy? Maybe - Tell me what you think. But whatever your view we can't ignore the positive impact that technology can make to self motivate learning at all ages and it has to challenge the fundamental ways in which we educate and train.
Ching's second study will be replayed by my daughter over the next two weeks who, having sat through her SATs, will be bounding around olive groves in Spain with a camcorder making the "TV channel with lots of cool programmes" that she's been itching to do for the past month - school got in the way of that creativity.

Smarter, Faster - research breakthroughs
What we are finding out about how our brain interacts with the outside environment, processes and stores information is poised to have a truly fundamental impact. The current institutional inertia within education and training is beginning to look like the proverbial leaky dam. -It's going to take more than a few fingers in holes to stop the whole thing tumbling down in the face of a flood of evidence, yes real evidence, that reveals how we really learn - not only that, how we can optimise that process.
Here's one study that particularly caught my eye:
Improving fluid intelligence with training on working memory
As reported by Wired:
Brain researchers for the first time claim to have found a method for improving the general problem-solving ability scientists call fluid intelligence, otherwise known as "smarts."
Fluid intelligence was previously thought to be genetically hard-wired, but the finding suggests that with about 25 minutes of rigorous mental training a day, healthy adults could improve their mental capacities.
Fluid intelligence measures how people adapt to new situations and solve problems they've never seen before. Fluid intelligence differs from crystallized intelligence, which takes into account skills and knowledge that have been acquired -- like vocabulary, grammar and math.
Subjects trained on a complex version of the so-called "n-back task" -- a difficult visual/auditory memory test -- improved their scores on a set of IQ questions drawn from a German intelligence measure called the Bochumer Matrizen-Test. (The Bochumer Matrizen-Test is a harder version of the well-known Ravens Progressive Matrices).
Initially, the test subjects scored an average of 10 questions correctly on the IQ test. But after the group trained on the n-back task for 25 minutes a day for 19 days, they averaged 14.7 correct answers, an increase of more than 40 percent. (A control group that was not trained showed only a very slight performance increase.)
Transfer of learning - or as I have discussed before the lack of transfer - is the elephant in the room. Most learning activities fail due to an inability to equip people with the "smarts" to apply what they know in one context into a new, even slightly different one. Given that the world we are entering is one of constant and increasing change, this is more than a worry. So, while it is still early days, reports that we are finding ways to develop models and tools that tackle this central pillar of intelligence is fantastic news.

Learning is a health issue
The old...
In some respects, you could say that the world of Education and Health are beginning to converge. The relatively new fields of neuroscience, cognitive psychology, and other studies of brain behaviour is starting to stray firmly into the more fluffy world of learning. This means we can start to view education as a brain health issue. This thought was triggered by a recent report by the National Institutes of Health (NIH) reporting that rates of cognitive impairment among older Americans are on the decline, with education associated with better cognitive health.
The data comes from the NIA-supported Health and Retirement Study (HRS), a national, longitudinal examination of health, retirement and economic conditions of more than 20,000 men and women over 50. Researchers tested memory and judgment of a large subset of HRS participants to determine cognitive status in two groups of people, those age 70 and older in 1993 and in 2002. The scientists then followed each group for two years to track death rates.
They also looked at levels of education, income, and other factors in each group, finding that the 2002 participants were wealthier and had significantly higher levels of education, with 17 percent college-educated compared to 13 percent in 1993. The analysis found:
Cognitive impairment dropped from 12.2 percent in 1993 to 8.7 percent in 2002 among people 70 and older.
Cognitive impairment was associated with a significantly higher risk of death in both cohorts.
Education and financial status appeared overall to protect against developing cognitive impairment.
Once older people with higher levels of education reached a threshold of moderate to severe cognitive impairment, they had an increased risk of death over the next 2 years compared to those with lower levels of education.
While health treatment has improved for stroke, heart disease, and vascular conditions the researchers also suggest that cognitive reserve - our mind's resilience to neurological damage - may explain why the higher level of education found in the 2002 study group may be influencing the lower rate of cognitive impairment.
The New...
A commercial sign of this convergence between health and education is the growing industry in brain fitness, largely triggered by Nintendo's Brain Training success on the DS and Wii. Much of this is opportunistic bandwaggoning. However there are some exciting developments in Scotland which are reporting real benefits in the use of brain training exercises in a school setting.
A study in Dundee led by Learning and Teaching Scotland, as reporting by the Times, found:
“The initial pilot project that used the Nintendo DS and Dr Kawashima produced fascinating results," Derek Robertson, a development officer for 'games-based learning' at the LTS, said.
“Not only was there a marked and significant improvement in attainment in mental maths but there was also an improvement in concentration levels, behaviour and self regulation in the learning process.” Over a 10-week period, students in years 5 and 6 at St Columba's Primary played a series of 'brain training games' – including reading tests, problem-solving exercises, and memory puzzles – for 20 minutes in the morning when classes began. In a maths test at the end of the trial, their performance improved by an average 10 per cent, and the time to complete the test also dropped from 17 minutes to 13 minutes and nine seconds. Some children halved the time it took to complete the test while either maintaining or improving their score, the study found.
This is more evidence of Less Learning More Often at work. The success is leading to an extension of the study to 16 more schools - buying 480 Nintendo DS consoles for £34,000. This a small investment given the potential return, even if you scale it up across the entire country. Compare this to the billions wasted by Governments on over-engineered support structures that attempt to prop up the traditional methods of learning support to little lasting effect. Learning Skills Councils come to mind but there are plenty of others littering recent history - I only mention these as the Government announces their closure in 2010.
If we start to view education and our capacity to learn as a social health issue, perhaps we will see better targetted funding and real analytical rigour becoming commonplace rather than the exception it is today.

'Millionaire' tests help kids learn
Replacing dry multiple-choice tests with quizzes akin to the hit TV show Who Wants To Be A Millionaire could help boost comprehension levels in children.
Tzu-Hua Wang at the National Hsinchu University of Education in Taiwan has devised a web-based multiple choice testing system with some fun elements influenced by the TV quiz. The system gives pupils the chance to "prune" away two incorrect answers from four - or, in a nod to "phone a friend", they may ask the class for help.
Unsurprisingly, children were more willing to be tested using Wang's system. But he also found kids had higher comprehension levels after using it, suggesting the system could be used for educational purposes.
This is interesting as it supports my view that DESIGN MATTERS. Engaging and holding attention is increasingly tough and just moving something online is not enough. Testing strategies really do need to move on from standard multiple choice mechanisms. This research demonstrates that different approaches can have an impact on learning effectiveness.
From Tzu-Hua Wang's paper, the use of an "Ask-Hint Strategy" turns what would otherwise be a standard web-based formative assessment into an online quiz game, called GAM-WATA (not quite as catchy a title as "Who Wants to be a Millionaire?"). The strategy consists of two elements: a ‘Prune Strategy’ and a 'Call-in Strategy'. The Prune Strategy emulates the "50/50" life line contestants are offered on the TV show, but contrary to the New Scientist report removes one option from four, not two. The Call-in Strategy provides the rate at which other test takers choose each option when answering a question. This I think is more like "Ask the Audience" than "Phone a Friend" as reported.
I'd like to understand better how they measured the improvement in comprehension amongst students taking these assessments, but it certainly illustrates that smart design does make a difference to learning outcomes.
It also shows that you should go back to the original research wherever possible as this seemed slightly misrepresented by the New Scientist report.

Our plastic brain - a game of give and take?
Indeed, as we specialise and become experts in a specific skill or knowledge area, then the brain area used most to support this activity grows. As an example, this comparative study of London taxi and bus drivers (Maguire, Woollet and Spiers, 2006) found:
...that compared with bus drivers, taxi drivers had greater gray matter volume in mid-posterior hippocampi and less volume in anterior hippocampi. Furthermore, years of navigation experience correlated with hippocampal gray matter volume only in taxi drivers, with right posterior gray matter volume increasing and anterior volume decreasing with more navigation experience. This suggests that spatial knowledge, and not stress, driving, or self-motion, is associated with the pattern of hippocampal gray matter volume in taxi drivers.
Taxi drivers navigate around a city demanding constant recall of the spatial area, adapting constantly to traffic flow, passenger preferences and other factors. Bus drivers, on the other hand follow a more limited set of routes.
Another study (Draganski et al, 2006) focused on German medical students demonstrating that extensive learning of abtract information in preparing for an exam (and comparing them with students not being examed), showed that:
During the learning period, the gray matter increased significantly in the posterior and lateral parietal cortex bilaterally. These structural changes did not change significantly toward the third scan during the semester break 3 months after the exam. The posterior hippocampus showed a different pattern over time: the initial increase in gray matter during the learning period was even more pronounced toward the third time point.
I wonder whether this suggests that cramming intensively - usually frowned upon but still a very common practice - has a more lasting impact on future learning and memory retrieval than we have assumed to date?
But then how does this sit with the other finding from Maguire's study that the brains ability to change to suit the tasks and activities we engage in, comes at a cost to other brain areas not used as intensively? In this case, they found that the ability to acquire new visuo-spatial information was worse for taxi drivers than bus drivers. This is the effect of the anterior hippocampus decreasing in size.
Curious.
With the growing use of MRI and voxel-based morphometry we'll be seeing more and more of these types of study informing our understanding of how we actually learn.

Knowledge Loses Its Luster

So, notwithstanding Marc Andreessen's (of Netscape fame) recently announced "death watch" campaign against print media, the NYT in particular, I have valued the highly edited version I get to see. This week I've been struck by the harmonious resonance of several short reports which I'll post on over the coming days. Here's the first:
In the US Knowledge Loses Its Luster
In short, people just don't think that this knowledge matters. In 2006 a poll found that nearly half of 18-24 year olds thought it unimportant to know where countries in the news are located. Only 23% could locate Iraq, Iran and Israel despite dominating the news and political agenda over recent years.
My immediate reaction is to defend these young Americans as I would say that not many Europeans could place many of the states that make up the US. And perhaps more importantly, what awareness do we all really have of the rapidly growing economies of India and China outside of a few major cities?
Jacoby partly blames a failing education system saying "although people are going to school more and more years, there is no evidence they know more".
This is interesting as maybe it's not as important to know these facts when you can look it up at the point of need, even fly in on a specific place in the world with Google Earth. When I need to know, I can easily get to the answer. Indeed, if you define learning as traditional education, then may be too much is a dangerous thing in this new networked, globalised world we live in.
The second trend of anti-rationalism is perhaps more worrying. However in a world which is changing at an ever increasing pace, in many respects the concept of fact being a static concept begins to weaken. What you knew to be true yesterday may not be true today. With such shifting sands, it's no wonder that evaluating the prevailing opinion is a more practical skill than vainly holding onto facts that may be irrelevant before you get a chance to apply it.
So what do you think? Does knowledge matter? Are these trends of real concern?

Six minute nap 'may boost memory'
Just six minutes "shut-eye" for volunteers was followed by significantly better recall of words.
"Ultra-short" sleep could launch memory processing in the brain, suggested the researchers from the University of Dusseldorf.
This follows on from my earlier post Snooze and Learn Faster.
It's too early to determine whether this study is significant (many other studies seem to think that at least 20 minutes is needed before this effect kicks in), but this line of research has got to have some impact on the way we structure our learning interventions so that we work with our natural brain/memory processing functions rather than fight against them.
