HACKR010The real 10 algorithms that dominate our world — Medium.

I’ve long thought that every discipline is its own culture. Each has a particular language, ways of working, humour, and generally looking at the world. For a computer scientist, everything is an algorithm.

  • to a musician, everything is a song.
  • to a writer, everything is a story.
  • to thespians, everything is a play.
  • to a film-maker, everything is a movie.
  • to a set designer, everything is a set.
  • to an educator, everything is a lesson.

I’m sure we could fill in a lot more….

Taylor & Francis Online :: Do Learners Really Know Best? Urban Legends in Education – Educational Psychologist – Volume 48, Issue 3.

Digital Natives, Learning Styles, Self-Educators.

Yup. None of these are backed up by any data. I have great respect for Marc Prensky, but the more we learn about living and learning with technology, the more I realize that most tech is magic to most people. Sure, kids may know how to take selfies and post them Facebook, but most of them really don’t know how anything works.

I would argue against the claim that learning styles don’t exist at all – it seems pretty clear that people have preferences and find some ways of approaching things easier than others, but perhaps a person’s preferred style changes depending on what they’re trying to learn. AND, while I usually try to provide a variety of ways to look at any topic I teach, I do not think we should pander to the students preferences, at least, not all the time.

I did have some fun mapping various learning styles and personality types onto games some years ago:

Becker, K. (2005) Games and Learning Styles Presented at the Special Session on Computer Games for Learning and Teaching, at The IASTED International Conference on Education and Technology ~ICET 2005~ July 4-6, 2005 Calgary, Alberta, Canada (accessible on ReaserchGate & Academia.Edu)

As for the final one, people don’t know what they don’t know. I am all in favour of giving my students all kinds of choices, but still guide them through it to make sure they meet up with the important parts.

This article takes a critical look at three pervasive urban legends in education about the nature of learners, learning, and teaching and looks at what educational and psychological research has to say about them. The three legends can be seen as variations on one central theme, namely, that it is the learner who knows best and that she or he should be the controlling force in her or his learning. The first legend is one of learners as digital natives who form a generation of students knowing by nature how to learn from new media, and for whom “old” media and methods used in teaching/learning no longer work. The second legend is the widespread belief that learners have specific learning styles and that education should be individualized to the extent that the pedagogy of teaching/learning is matched to the preferred style of the learner. The final legend is that learners ought to be seen as self-educators who should be given maximum control over what they are learning and their learning trajectory. It concludes with a possible reason why these legends have taken hold, are so pervasive, and are so difficult to eradicate.

Curiously both the first and last myths were very popular at the school where I did my PhD. Given that we still effectively have the same people running the Ed Tech area, I would imagine they still are.

COMP110 Essential Tips For Meeting Tech Needs of Low-Income Schools | MindShift.

  1. Keep goals and mission in mind.
  2. Tech should complement not replace.
  3. Involve families.
  4. Don’t let trends dictate decisions.
  5. Support teachers.
  6. Use tech to free up teacher time.
  7. Track data.
  8. Expect excellence, not achievement.
  9. Understand start-up world.
  10. Build relationships with vendors.

This is a good list.

Many years ago, when my son was in grade 2 his school had a parents meeting to discuss the purchase of new computers. They’d come into some money and wanted to buy some new equipment.

My husband (also a computer scientist) and I sat in the meeting for some time, listening to their tech guy talk about the features of the computers they wanted to get – they sounded cool – they had all kinds of bells and whistles. After some time, we stood up and asked what the school planned to do with the computers, you know, how they intended to use them for learning. The room went silent. They had been so busy looking at hardware and other do-dads, that they had not actually thought about why they wanted them in the first place. We made some suggestions, but the conversation went back to hardware features and cool do-dads as soon as we were done.

The school ended up wasting a pile of money on computer equipment they had no idea how to fit into their curriculum.

I suspect that in most schools very little has changed.

  • Make every moment the player spends in your game time well spent.
  • Spend that time entertaining and rewarding the player for choosing your product.
  • Challenge without frustrating, and guide while still keeping the player in control.
  • Your world, your choice. If something isn’t fun, don’t put it in the game.
  • Keep the player in the game as often as possible.
  • But let him leave whenever he wants.
  • And remove any barriers that stop him from picking up where he left off..
  • Keep it simple, keep it accessible, and keep it fun.
  • Don’t demand a huge time commitment from the player or dictate the length of his sessions; let him take it at his own pace.
  • Don’t fix things that aren’t broken.
  • Test with a wide spectrum of players and non-players to find out what’s intuitive and well-received.

“”I can afford to buy any game I like; but I rarely have the opportunity to play them.”

This sentence embodies the sad reality that has hamstringed my gaming hobby since becoming an unwilling maze-dweller in the rat race of full-time employment. Four years ago, when not otherwise distracted by the mundanities of dodging college work or chores, I could (and did) devote countless hours to the challenges and pleasures of digital worlds. My funding was limited, but I took pride in completing every game, every cover disk demo that I purchased. I reveled in replayability, gloried in gameplay depth, marveled at multiplayer. Life was good.

“So why should I care, you nostalgic cretin?” I hear you ask. Why? Because my cubicle-dwelling cogs and I represent a substantial slice of potential software sales.

We balance on the knife’s edge between our glorious time-squandered youth, and the commitments of inevitable middle age. However, the needs of independence (and dependents) have forced us to adapt our playing style to meet our circumstances. Most gamers in this range still game whenever they can, but lack the time to maintain their previous commitment, especially when wives, children, and other such distractions enter the mix. If games can adapt to the needs of the working gamer, they can find a lucrative niche. If not, we will have no choice but to leave our childhood behind and surrender to mundane reality. And when we do, we will take our regular monthly salaries with us.

Here’s a few suggestions to better accommodate the time-deprived; many of these ideas could also create a more enjoyable gaming experience for all:”

Seven Key Elements of Gamification, Plus or Minus Two

Approximate Reading Time: 6 minutes

gamificationA little while ago I wrote a reaction to a post about 8 steps to make your course less boring, and at the end of it I promised to post my own list. Here it is.

I will qualify this list by saying that my interest is in gamification for learning – I currently have no interest in gamification as marketing or for business more generally.

Good gamification is not about adding badges, or leaderboards, or even about a narrative that makes each learner the“hero” of their own story. A good gamification design draws upon the best aspects of games and incorporates those into the very core of the course design. Good gamification is about altering the fundamental ways in which learners can progress through a course, demonstrate mastery, and earn grades.

I’ve decided to use George Miller’s “Magical Number Seven, Plus or Minus Two“, so my list consists of 9 things. 5 are essential; 2 are nice to haves; and the other 2 are optional …..

  1. badge01FLEXIBILITY: This is a big one, and there are two main approaches: one for how to get through the content, and the other for how to demonstrate mastery. Giving learners choices is key to helping them take ownership of their own learning.
    1. FLEXIBLE LEARNING PATH (Choice I)
      Most traditional courses are presented in a linear fashion. If there’s a course textbook, then it is common for the course to follow the textbook from beginning to wherever the course ends. In fact textbooks are often selected specifically for their fit with a pre-determined linear progression through the course ‘content’. The truth of the matter is that many subjects don’t actually lend themselves to a nice linear progress through a series of topics. Laying out a course map that identifies key concepts, topics, and skills and then creates links between those that rely on each other allows for learners to choose a variety of paths through the course material. It also helps both the instructor and the learners see how topics are interrelated. If they are struggling with concept ‘D’, and it relies on an understanding of concepts ‘F’ and ‘P’, then perhaps going back to those and working with them more will make a second crack at topic ‘D’ work out better.
    2. FLEXIBLE ACHIEVEMENT PATH (Choice II)
      Most traditional courses present the learner with a specific set of tasks to complete. These usually include a set number of assignments, quizzes, tests, and exams, possible papers to write, and sometimes smaller activities or credit for participation. Many courses have hard deadlines for assignments?—?some even reject submissions if they are late, no matter how well they were done. In order to earn a perfect score learners often need to get a perfect score (or an ‘A’) on each and every item. A bad day, technology failures, or a forgotten assignment can cost them an ‘A’, even though they have mastered the material. This kind of grading is often more about compliance training than measuring subject mastery. A flexible achievement path is one that provides the learner with multiple ways to demonstrate mastery. It also allows for a learner to make up for a missed or inadequate assignment by providing alternate assignments, re-submission, and flexible deadlines whenever possible.
  2. REWARD STRUCTURE: Points for things done well/right.
    Grading should be cumulative rather than reductive. Scores should not go down, only up. Sure you can take away points, but unless your intent is truly to punish the learner for something (and there might be valid reason for doing this), then taking points away in a context where people are earning points for demonstrating competence is effectively saying the learner has UN-learned something. That doesn’t make any sense. Unless there is an extremely good reason for it (like this is a crucial element of a life-saving procedure) there should be no single quest that can result in a learner failing this course.
  3. CLEAR RULES
    Make your rules clear, and make sure everyone know what needs to be done and how it needs to be done. Connect all required activities to the course objectives. Your rules should be laid out at the very start of the class, and most, if not all quests should be available, along with their assessment criteria right on day 1.
    Also make sure that it is possible to earn a perfect score. A gamified system is never graded “on a curve”. If everyone in the class earns enough points to qualify for an ‘A’, then everyone in the class should get that A.
  4. QUESTS
    Quest is simply another word for the tasks that the learners are to complete. It doesn’t really matter if you call them assignments, learning tasks, quests, or something else, although I have found that using the word “quest” has opened up possibilities I would not have considered when I called them assignments.
    Each quest should connect with at least one node in your learning path map. If not, you seriously have to ask yourself why you are asking your students to do this. You can use game vocabulary here, or not, depending on your audience. The use of game vocabulary (i.e. naming quests according their type, such as ‘defend’, talk-to’,’epic’, etc.) can help to underscore the fact that the approach in this course is different from what most of the learners will be used to.
  5. FEEDBACK
    Feedback must be timely. In a game, players watch their scores change immediately as they perform various tasks. Having a variety of both large and small quests allows learners to do do little things to increase their score (and confidence). If these are not assessed quickly and their scores adjusted appropriately, you undermine the motivation to complete the tasks?—?especially the smaller ones.
    ———————————————————————–
  6. BADGES – OPTIONAL
    Badges, when used, need to be connected to meaningful achievements. They should not normally be used for things everyone will do. Badges should not be a surprise. Take a lesson from the Boy Scouts on how to do badges well. Each badge should be associated with a clear set of criteria for how they can be earned. You may even allow for several ‘grades’ of badge (bronze, silver, gold, for example). If you are not going to do badges well, then you are probably better off not using them at all.
  7. LEADERBOARDS – OPTIONAL
    Leaderboards have been a common external motivational tool (weapon?) in marketing and sales for decades. They drive competition, but it is not clear that they actually drive learning. Competition tends to motivate extroverts, but it tends to DEmotivate introverts. In many formal educational situations, you will not be allowed to associate grades or scores with learners by name, so be very careful with how you post and use leaderboards.
    ————————————————————————
  8. AVATARS – OPTIONAL
    Many people associate avatars or game characters as essential elements in games, but in a gamified learning context, the use of avatars should be optional in most cases. However, avatars can be a mechanism that allows for the publication of achievements via badges and leaderboards?—?so long as the real life identities of the avatars is known only to the individual student and the instructor. Avatars can also be treated more casually as simply profile images. If they are to be used as profile images, then having some connection with the real person (appearance, hobby, etc.) can help to build or strengthen a sense of community. This can be especially helpful if it is an online course.
  9. NARRATIVE – OPTIONAL
    Finally, narrative or storyline, although it is often one of the first things many talk about when they talk about gamification, it is probably the most expendable. Unless you are teaching a course where a narrative is a natural fit (such as a literature class, or a case-based course) imposing a narrative on a course can easily backfire. A poorly designed narrative is almost guaranteed to disengage your learners, which is exactly the opposite of most people are trying to achieve through gamification. If you are going to use a narrative for your class, make sure that all of your topics, quests, and other activities tie in to the narrative, or you run the risk of falling into the same old trap of assuming that a game-wrapper will somehow magically increase engagement. It won’t.

You may have noticed that Levels aren’t included in the list. It’s not that they aren’t useful, but they should not be allowed to stand alone. When used, they can form support structures for both the learning path and the quests. Levels can be determined simply on the basis of how many points the learner has earned, or they can be more complicated, allowing for certain rewards and quests to be unlocked only once a particular level is reached. They can serve as a useful mechanism for ensuring the completion of certain tasks before others are attempted.

There is more to this of course?—?MUCH more?—?and there are specific ways in which these elements can be implemented effectively. It is very easy to get carried away and create a very complex system. It is extremely important to remember that most people play games voluntarily while very few people will be taking your courses simply because they want to. This means you must remain sensitive to the extra load being placed on your learners by the gamification system. Keep it relatively simple so learners can get started quickly and so they can spend time on the course content rather than learning the rules of your game.

Weekly Web Round-Up (to July 19, 2014)

Approximate Reading Time: 5 minutes

We have a lot this week:

“Most people involved with games and learning are familiar with the work of James Paul Gee. A researcher in the field of theoretical linguistics, he argues for the consideration of multiple kinds of literacy. The notion of “New Literacies” expands the conception of literacy beyond books and reading to include visual symbols and other types of representation made possible through, among other things, current digital technologies.

At this point in the evolution of education, it’s critical that we expand our conception of literacy to include more than just words. In fact, we may need to reimagine how we nurture early literacy to make sure we provide a foundation not only for reading, but also for “New Literacies.”

In the following conversation with Gee, we discuss literacy, systems thinking, education, socio-economic inequality, and, of course, video games.”

While I do agree with the idea that we should include more in our conception of “literacy” than words, I really don’t think it’s helpful to connect schools with the word ‘prison’.

“So Long and Thanks for All the Fish

I just got off the phone with Mike Lee, the founder of Edshelf, a startup that recently announced it was closing its doors at the end of the month.

There’s been a grassroots hashtag campaign on the part of some educators to #saveedshelf, and while I understand the good intentions — Mike is a great guy, and it sucks that his startup isn’t successful — I’m not sure I understand why this particular startup should be saved. I’m not sure why we’d believe that an expression of support via social media would trump revenue. Retweets don’t pay the bills, yo. Indeed, I think the whole thing comes close to reinscribing a dangerous narrative being promoted by investors and ed-tech industry cheerleaders that scale scale scale matters and then magically the money will follow. “

Any time entrepreneurs catch wind of some field they may be able to mine for profits, you get startups popping up all over the place. Many do not survive, even though they may have one or two really good ideas. Another bunch die because they didn’t actually know anything about the field in the first place. Sadly, there are also some in the latter group who survive, so wading through what’s left after a fall is no guarantee of quality.

“Why does such a vibrant and promising industry keep losing its most veteran and celebrated developers?

By: Liam Boluk

In many ways, the video gaming industry has never looked more promising: smartphones and tablets have massively expanded the addressable market; wearables (including virtual and augmented reality devices) are enabling new interaction models and experiences; and user generated content allows studios to add depth and re-playability at little-to-no cost. In 2013, the industry generated more than $65 billion in revenue – representing a nearly 30% increase in only 5 years and totaling 82% more than the global box office and 3.2 times the size of the recorded music industry. Despite this, brand-name studios – including some of the most celebrated and commercially successful ones – continue to hemorrhage or shut down entirely.”

I think a lot of them die because they aren’t dong anything new.

Today’s tip comes courtesy of blog reader, Daniel Albarrán. He sent me an email stating that once he understood the versatility of PowerPoint it opened his eyes to all sorts of possibilities—one of them being the ability to create illustrated characters.”

“But, with all appropriate respect to the coders and designers who slaved long hours to bring us all this entertainment, not all of these games are wildly original masterpieces. Just as in the worlds of film or books, there are an awful lot of ‘me too’ properties that try to expand on, improve on, or just plain rip off great games of the past.

It would be folly bordering on madness to try to pick out those rare games in history that actually did something new. The games that made the gaming industry what it is today. Guess what we’re going to do…”

Not sure I agree with all of these, but there you have it.

“If it’s true, in Sir Ken Robinson’s words, that “Creativity is not an option, it’s an absolute necessity,” then it’s that much more imperative to find ways to bring creativity to learning.

But first, we have to understand what conditions foster true creativity. One definition that scientists have agreed upon for creativity is the ability to create something that’s both novel as compared to what came before, and has value. “It’s this intersection of novelty and value, a combination of those two features that’s particularly important,” Dr. Robert Bilder, a psychiatry and psychology professor at UCLA’s Semel Institute for Neuroscience and Human Behavior. In any system, there are forces pushing towards organization and others introducing unpredictability. A truly creative idea straddles both of those states.

“The truly creative changes and the big shifts occur right at the edge of chaos,” Bilder said.

For educators who have embraced the notion of the tightly controlled classroom, it’s a worst-case scenario. But Bilder has a reason for this theory. He tested it by asking children what aspects of a learning environment make them feel most creative. “One of the things they found most valuable in their arts classes was the freedom not to have to seek right and wrong answers,” Bilder said. “It was that freedom to explore that led them to be increasingly engaged and allowed them to forge connections that allowed them to be more creative.””

“Competition. The word conjures images of people pushing and shoving, trash talking, the exulted winner standing above a field of downtrodden losers. Not exactly what most parents consider healthy or constructive for their kids’ development.

Po Bronson presented a very different picture of competition when he spoke with Michael Krasny on KQED’s Forum about Top Dog: The Science of Winning and Losing, his latest book written with co-author Ashley Merryman.

The book examines competition from all angles – physiological, psychological, historical. Their main point: competition, if done right, is a good thing. In fact, competition and team activities can drive learning and performance better than solo endeavors.”

“This intricate Maltese Falcon­-like story will unfold each day, over the course of semester, as a multiplayer game at Renssalear Polytechnic Institute in New York. It is being designed as a language-learning exercise by Lee Sheldon, an associate professor in the college’s Games and Simulations Arts and Sciences Program. “Using games and storytelling to teach­—it’s not that radical of a concept,” says Sheldon. “It makes them more interested in what’s going on.”

Sheldon is a pioneer in gamification, a new movement that essentially takes all the things that make video games engaging and applies them to classroom learning. Sheldon started developing the theory eight years ago. Since then, gamification now comes in all shapes and sizes and is used across educational levels, for kindergarteners through adult learners. Its practitioners range from individual teachers experimenting with game-like elements in their classrooms to entire schools that have integrated the games into their curricula. “

coldantlerfarm: An Open Letter To Angry Vegetarians

Approximate Reading Time: 3 minutes

Your lifestyle contributes to the destruction of natural habitats, and that includes the deaths of many animals.

Eat in whatever way invokes respect and gratitude in your soul. Be grateful we live in this time of contrived and soon-to-be over luxury and abundance. But do not come to battle here, accusing those of us raising good meat of murder. Those are fighting words, unkind words, and for someone so intensely passionate about treating animals well you seem to have no issue treating human beings like crap. I’m an animal, too. I would appreciate some ethical treatment.

You can read the original full blog post here: coldantlerfarm: An Open Letter To Angry Vegetarians.

2012-09-17_13-09-23_wmI’ve never been a vegetarian, but this post expresses my thoughts very well.

The western vegetarian diet is possible because of our luxury and abundance. Yes, of course many poor people in under-developed countries eat vegetarian diets out of necessity. They also have much lower life expectancies than we do, so I assure you, you do not eat like they do, and most of them would eat meat if only they could afford it.

I know that I do not need to eat meat to survive, but I also know now that it is impossible for me to live without killing. It is impossible for you, too. I think this is the heart of our misunderstanding. This is why PETA and the FTCLDF are not working together to be one giant powerhouse for good and ending animal suffering. Most animal rights activists do not acknowledge (or perhaps are not aware) that every meal includes death. The simplest backyard salad from your own organic garden to the fake bacon in your shopping cart — both take lives. I have simply chosen to take lives in a way that causes the least amount of suffering and causes the least amount of wasted global resources. And yes, it means there is blood on my hands now.

Attention vegetarians and vegans: your lifestyle contributes to the destruction of natural habitats.

The truth is there is no meal we can eat without killing. None. A trip to your local grocery store for tofu and spinach may not include a single animal product but the harvesting of such food costs endless animal lives. Growing fields of soy beans for commercial clients means removing habitat from thousands of wild animals, killing them through deforestation and loss of their home. Songbirds and insects are killed by pesticides at legion. Fertilizers are made from petroleum now, and those fields of tofu seeds are literally being sprayed with oil we are fighting wars over. Deer died for that tofu. Songbirds died. Men and women in battle died. And then when the giant tofu factory harvested the beans they ran over those chemical oil fields of faux-food with combines that rip open groundhogs, mice, and rabbits. Tear apart frogs and fledgling birds. It is a messy and bloody business making tofu or any of that other non-murderous food.

THIS is especially important:

I eat animals I raise myself because I want to eat local food that causes less animal suffering and empowers my local community. I live in upstate New York. A place where farming vegetables does not make sense. This is a far cry from southeast Asia or southern California. Our growing season is around 100 days. What we can grow here in bulk is grass, and by extension the meat that eats the grass. We can let hogs range our woods and eat grubs, vegetation, and nuts. We can buy local non-GMO feed grown by our neighbors and give our animals full lives, outdoors and on pasture! Eating meat here is eating in a way that respects our region’s food shed.

We can graze our animals in ways that returns good nutrients to the soil and heal the earth. We can grow two or three harvests of those grasses and feed them to animals like sheep, cows, and goats all winter. This is what my part of the world eats if they are serious about saving the environment.  We can do this without using a lot of oil, close to home, and harvest the animals we know without driving to a store to waste gas, plastic bags, and pave another parking space. When I kill a chicken I end one life. A life I was present for, grateful for, and worked hard for. I have a hard time taking criticism seriously from someone who swipes a credit card for a bag of groceries they have convinced themselves is more righteous, having never weeded a row or hefted a bag of feed. A really hard time.
