9.5.2013 Counting Drumbeats: Should our number syllables represent quantity?Excerpt from Doug Clements "Subitizing: What is it? Why teach it?' "Three pictures hang in front of a six-month-old child. The first shows two dots, the others show one dot and three dots. The infant hears three drumbeats. Her eyes move to the picture with three dots." IMAGINE: This ability of recognizing syllables, movement, and number is born within us. We have the capacity to recognize a four digit number instantly if it consisted
of four syllables. Our language does not facilitate our natural
instinct. 4,367 is a ten-syllable number. No wonder our brains get
confused! With subQuan and the slight change of two single digit numbers
-ro for zero and -ven for seven, we are able to make these larger
numerosities accessible to younger children: four three six -ven.
Visualizing numbers in their shapes allows yet deeper understanding (as seen below).-ro, one, two, three, four, five, six, -ven, eight, nine, repeat.... We can now discuss numbers in various containers or bases. We don't always package things in tens. The picture below was a fun adventure in Walmart at all the different container sizes we use. Chinese language has made it easier on their children with counting. Instead of introducing a whole new set of words after ten, they say ten one, ten two, and so on. We could do the same. Remember the push to change 9-1-1 emergency number to the single digit saying of it rather than nine-eleven? That's because in an emergency, when the brain is stressed, it can't find the eleven key on the phone. The only numbers on our digital devices are 0-9, so logically saying one-ro for ten, one-one for eleven, and one-two for twelve would make it much easier for our children to understand number. We could then catch up sooner with the Chinese as seen in this graph below. Interesting thoughts based on well-documented research. The investigation continues... Retrieved from the ning.... Cooper's Blog Posts: Using games to create engagement in education, business, and government posted 8/5/2011 3D Game Lab continues to bring incredible value to the Dream Realizations effort to help people understand numbers. In Tom Chatfields 7 Ways to Reward the Brain, he leads the viewer through seven key game concepts that when combined in addressing a given issue or problem create engagement! DR is focused on creating engaging activities around the fundamentals of number sense to ensure that as many people as possible will be motivated to discover for themselves that they can understand and change their lives by increasing their knowledge of numbers. Numbers, in themselves, are boring or scary to most people because they simply haven't had the right foundation for understanding them. It is very difficult to engage people who have already tried to understand numbers via mathematics and ended up thinking that they were not 'bright' enough to get it or that there is any value in their personal lives to tackle this subject. 3D Game Lab is providing a game foundation exhibiting many, if not all, of Chatfields 7 Ways to Reward the Brain discussed in the video. DR's entire staff is currently participating in a three week intensive study of 3d Game Lab. Please stay in touch to see the exciting results. We hope you will take time to not only view the video but also to visit 3D Game Lab's website. 3D GameLab and teaching subQuan posted 8/3/2011 According to many experts, Jim Gee included, the United States education system has the potential to undergo a dramatic paradigm shift due to the demand of innovation in face of world-wide competition. I have seen the potential for games in education since the mid 1960's and now the day of game-based education is dawning. As Jim points out in his video, kids want to participate, they want to be engaged. Games are engaging and they require their own levels of knowledge acquisition. Unlike school, games do NOT separate learning from assessment. Games are always assessing. Furthermore, reference material (on-line help, user guides, developer notes) all make sense once one has stated to play the game. The game allows you to play first, then access relevant data once you know that you don't know something. Jim calls this 'language on demand'. I agree with Jim that vocabulary reading and writing develop as students interact with one another and with research material. The language is built as needed. Repeated internet searches on a new topic, say 'subQuan', reinforces not only the spelling of subQuan but also the fundamental concepts since they appear on a search's findings. Also, the language is reinforced by top gamers as they have a high set of standards on who is considered 'top' and using the right vocabulary is an excellent differentiator of expertise. I actually used this understanding of terms to rapidly separate applicants in a Silicon Valley billion dollar firm. There were certain vocabulary terms that were just fundamental to certain levels of expertise.
At Dream Realizations and ItOnlyTakes1, education and games are inseparable. SubQuan is a fundamental concept that the eye 'sees'. It doesn't require learning of a process, once you see, you see! Putting this new concept into a game environment is fundamental to our goals. We are all engaged in Boise State University's beta course on 3D Game Lab this August, 2011. We look forward to teaching and learning with our students. We will be initially using Second Life to accomplish this and, hopefully, 3D Game Lab as our engine.
Watch Jim Gee: http://www.youtube.com/watch?v=JU3pwCD-ey0&feature=player_embedded subQuan question worth investigating posted 6/20/2011 Is there a proof that there is only one complement that is contained for any shape? I.e. if you have the number 7, the segs complement is 10 -3 (1, -3), the squares complement is 100 -90 -3 (1,-9,-3), the cubes complement is 1000 -900 -90 -3 (1, -9, -9, -3), ... The negative complement or the second segs, squares, cubes, etc complement requires free mode (when the value in any shape(base place) exceeds the base). [NOTE: Please comment if this is partially confusing so that I know what to clarify.] Subitize is not required for subQuan!!! posted 4/10/2011 Wow! I never expected to discover that the ability to subitize was NOT foundational to the ability to subQuan. I always focused on Stanislaus Dehaene's neuropsychological research on number sense as the explanation for the efficacy and quickness of subQuan. However, both my co-researchers became aware that counting, albeit much slower, was just as effective as subitizing in determining the subQuan of a number. In retrospect, the invention of place-value was not beholden to the methodology of determining the quantity within each place-value. SubQuan continues to reveal very fast and powerful visualization of mathematical structures resulting from its definitional representation of numbers in every base system but it no longer depends on the ability to subitize. This does not mean that Dream Realizations will abandon its efforts to promote subitizing. We still believe assessment of pre-college mathematical abilities should be based on velocity, perhaps even acceleration, rather than distance. [To clarify this last statement, assessment is dominantly based on arriving at a correct answer (distance) rather than the time it takes to derive the answer (velocity).] Changing the website: what was I thinking? Does this affect our other technology decisions? posted 4/10/2011 Over the last Christmas season we discussed an idea of mine to make the website visually driven rather than text driven so we made some changes. Over the past three months we did not get the results we were hoping for so we are in the process of moving back to the Ning-based website. I am hoping that this adventure into visualization does not deter those who are following us early on. Upon reflecting, I believe traditional web-surfing for 'just the facts' lends itself to text-based web design such as Ning. However, I still firmly believe that when building foundations for knowledge acquisition and social learning relationships that visually driven immersive technologies, such as Second Life, will become more and more dominant and any visualization facilitating this movement will be very successful. Therefore, expect our actual coursework to appear first in our laboratory in Second Life, then in an OpenSim environment for easy transfer of scripts, textures, objects to give access for young dreamers. We will utilize those immersive environments to create machinima (Videos made within an immersive environment) to provide exposure for non-immersive collaborators. Hopefully, we will then translate our findings into the emerging touch technologies of iOS. [Just a reminder, please help however you can. We eagerly accept any and all input and ideas, especially from our young dreamers. No matter how young, get involved. It's your future.] Four Steps to Polynomial Derivation (steps 3 and 4) posted 12/3/2010 3) Differences: Discover the relationship that differences have with metapatterns. When we examine the quantities creating one digit metapatterns and then two digit metapatterns, we can discover a simple way to discover the metapatterns from the data by using differences. In the data associated with these metapatterns, we would have discovered by looking at different metapatterns that the first difference determines the value of the 'seg' and that when that value is removed from the data, the resulting number is the value of the 'remainder'. Having access to these sheets enables very quick discovery of this fact. 4) Polynomial Derivation: Develop an expression for the pattern from differences. When this examination of metapatterns continues into squares and cubes, the pattern of differences reveals itself in all its glory. A spreadsheet is easily created to automate the differences, determine whether we have a seg, square, cube, seg of cubes, et al., and to determine the coefficient which turns out to be the value within the metapattern. Removing the effect from the data and repeating continues to give us significantly smaller shapes until we get to the remainder. Expanding this metapattern to base x then reveals the equation for the metapattern. The metapattern 1234 (pronounced one-two-three-four) has the data that generated it placed into the spreadsheet and the equation +1x^3 +2x^2 +3x^1 + 4x^0 is automatically generated. Having established the simple rules of deriving a polynomial from metapatterns, new data that is not conducive to Base Number Sheets, such as positive and negative non-integer coefficients are still derivable by the rules. View-only spreadsheet at http://bit.ly/i8sqfA . Conclusion The ability to visualize numbers, SubQuanning, observe the metapatterns, see the importance of differences, and then derive the polynomials lay the foundation for a rich, powerful, and easily understood foundation for science, technology, engineering, and mathematics (STEM)!! Four Steps to Polynomial Derivation (steps 1 and 2) posted 12/3/2010 1) SubQuanning & 3-D SubQuanning: Learn how to name quantities in containers. The foundation of numbers must start with recognition.
Traditionally this is taught at the same time as the alphabet. (See
'Teaching Counting') Regardless of where an individual is in their
understanding of numbers, the recognition of numbers by SubQuanning is
absent due to SubQuanning's recent discovery. In 2008, www.itonlytakes1.org
was developed as a prototype to enable number recognition by
Subquanning. A visit to this site reveals five discoveries, named
Discovery 0 through Discovery 4. For each Discovery there are three
buttons: discover, hone, and master.
The discover button reveals what is to be covered. The hone button
generates a more varied sample for discovery, and the mastered button is
not currently enabled. Briefly, Discovery 0 establishes a base line for
an individuals recognition and key-press response times as the numeric
symbol is displayed along with a SubQuanned quantity. Discovery 1 allows
individuals to discover that they can recognize quantities instantly
(This is very close to the concept of subitizing except for the
organized layout.). Discovery 2 displays two base A (ten) digits to
scale. Discovery 3 displays two digits in a random base, and Discovery 4
displays three normalized base A integers.
Either using physical or immersive manipulatives enables the
discovery of a 3-D naming convention: segs, squares, cubes, seg of
cubes, square of cubes, cube of cubes, seg of cube of cube, ...
The naming discovery starts with recognizing the cube and square
shapes then reducing the dimensionality to one, usually garnering the
name 'line' for the first container. However, lines are infinite which
leads to the term 'line segment' and when reduced to the monosyllable
'seg'. It is not a big step to recognizing a similar big seg to the left
of the cube which is appropriately called a seg of cubes. The smallest
unit, which does not fill a container is accurately called 'remainder'.
2) Metapatterns: Observe that different quantities in different sized containers can have the same name.
Perhaps
the easiest of all steps is recognizing the same SubQuan in different
bases. Although the quantities are different, the same expression of
SubQuan can be identical. The SubQuanned metapattern, 56, pronounced
five-six, is readily apparent in the following three bases.
Avatar Physical Interaction posted 6/2/2010 I continue to think about how t make avatar interactions more real and personal. I definitely believe that creating a range-of-motion animation where we move the left arm around in a hemisphere and the left arm around in a hemisphere we can identify the ideal animation to engage so that avatar to avatar interactions align. For example a tall and short avatar will interact with different animations than two tall or two short avatars. ___________________________________________________________________________________________________________________________________ Rebecca's Blog Posts: DR @OSU ELC on AdobeConnect posted 5/29/2012 The theory of subQuan - for Emergent Learning Commons Cooper and I presented on Adobe Connect today.

(1999) posted 5/28/2012 Excerpts from Douglas H. Clements http://www.google.com/url?sa=t&rct=j&q=&esrc=s&sour... Subitizing is "instantly seeing how many." From a Latin word meaning suddenly, subitizing is the direct In the second half of the century, educators developed several models of subitizing and counting. They But how is it that people see an eight-dot domino and 'just know" the total number? They are using the Children use counting and patterning abilities to develop conceptual subitizing. This more advanced ability to The spatial arrangement of sets influences how difficult they are to subitize. Children usually find Certain arrangements are easier for specific numbers. Arrangements yielding a better "fit" for a given If the arrangement does not lend itself to grouping, people of any age have more difficulty with larger sets Use conceptual subitizing to develop ideas about addition and subtraction. It provides an early basis for Children can use familiar spatial patterns to develop conceptual subitizing of arithmetic. For example, "Subitizing is a fundamental skill in the development of students' understanding of number" (Baroody References The Number Line is a Cultural Construct posted 4/28/2012 Michel Paul, from the Math 2.0 discussion group, posted a great article link about research documenting that the number line is not an innate construct, but rather a cultural one. The following is the initial post: http://www.eurekalert.org/pub_releases/2012-04/uoc--sft042312.php OK, this has me curious. Animals other than humans can subitize. Chimps can subitize better than humans. There does seem to be a kind of fundamental number sense that is hardwired into some animals that include us.However, this
article points out the very interesting fact that the number line we
consider so fundamental is a cultural construct.
"After confirming the Yupno participants' understanding of numbers with piles of oranges, the researchers gave the number-line task to ..." OK, so they verified an 'understanding of numbers' before testing the number line concept.
Wouldn't subitizing have a lot to do
with how we can, for example, correspond our fingers with groups of
objects? So maybe that's why chimps can subitize better than us? They
can manipulate their toes as though they were fingers?
-- Michel
And to that is my response: I noticed that it is the ordinal process that seems to be in
question, not the natives ability to understand quantity. This leads me
to believe that teaching our kids first how to count instead of random
(or in our case organized- subQuan) subitizing leaves them at a
disadvantage with their innate ability to understand number before
symbols are introduced. Is our culture programming over our natural
capabilities? Have we simply jumped too quickly to the abstract in our
educational system and not solidified the correspondence of our fingers
(and toes - heehee) with groups of objects. I was also quite fascinated by the representation of time (past, present, & future) of the indigenous people. Definitely a cultural thing. Read the article to find out more!! :-) First sQi3d Sushi Bar Group Presentation posted 4/10/2012 Dream Realizations just finished a guest presentation with Rawlslyn Francis from Florida State College at Jacksonville via Second Life live at the 23^{rd} International Conference on College Teaching and Learning (http://www.teachlearn.org/workshops.html). We talked about our tools and content, but most importantly, we highlighted our sQi3d Sushi Bar and its capabilities. With a maximum capacity for 42 avatars, we can give synchronous lessons and group presentations. If you would like to schedule a presentation to your institution, now would be a great time! Come to Boise State EdTech Island to visit our group learning station located at: http://maps.secondlife.com/secondlife/EdTech/80/89/26 In other news, we have new videos up on YouTube. Check out the DR playlist: http://www.youtube.com/user/DreamRealizations/videos?view=1 Thoughtful Ponderings from a Cognitive Engineer posted 3/23/2012 Cooper's post to the Math 2.0 group: I am not a math professional. I am an engineer by schooling, twice in fact. However, I have a problem right away with the referenced article by Peter Gray. "The first step in coming to grips with math is to knock it off its pedestal. The real-life problems that are important to us are problems like these: Whom should I marry? Should I marry? Should gays be allowed to marry? What career should I go into and how should I prepare for it? If I invent gizmo X, will people buy it? Should corporations have the same constitutional rights as individuals? What's the best way to unplug the toilet? Math plays little if any role in solving such problems, nor do such problems have clear-cut right or wrong answers, demonstrable by some formula."He advocates knocking math off its pedestal based on his alleged belief that math doesn't address a list of real problems he states. Hmmm, let me apply my engineering eye to these and tell you what I see. "Whom should I marry? and Should I marry?"
It seems prudent to me, growing up in
a family of seven kids and seeing many marriages not only within but
without, that by pure observation of those that are successful versus
not, certain 'math' concepts come to mind.
1) Compatibility: HOW MANY activities do they agree on (from vacation to cleaning to raising children, etc.)
2) Handling finances: nothing is more
MATHEMATICAL than handling money and, I will leave this exercise to the
more robust researches in the group, that money problems are one of the
top causes of divorce.
"Should gays be allowed to marry?"
Hmmm, sounds like a religious question. Psalm 1 comes to mind. But
back to math and more specifically the numbers involved: how many gays
want to get married? What is the correlation between married gays and
the rest of us? How does this affect our economy? Every single attribute
in this debate can be assigned a numeric consequence except the
religious view. And for those, I recommend you start with Psalm 1 before
you go into the law making business. Just a thought, not a request for a
religious discussion in Math 2.0.
"What career should I go into and how should I prepare for it?"
If your still reading, bless you. This is the ultimate statement of ignorance about math and life. Your career should:
1) make you happy (you better have a
list of importance on what makes you tick. You should CORRELATE an
estimation of your desires with those that your career choice offer.
Just taking an exam for determining your fit for a career involves
substantial mathematics on analyzing your psychological makeup.
2) provide for you. Again, back to finances. Will you come out positive in life. Nothing could be more 'math' than this!!!
"If I invent gizmo X, will people buy it?"
OMG. I have started six companies and worked for thirteen others.
We were always analyzing what it took to get people to 'buy' an idea or
product and it was ALL MATH: % of people you could reach, % of people
that would be interested once reached, % of people that would watch a
presentation, and so on. OMG, how could anyone answer this without
math!!!!
"Should corporations have the same constitutional rights as individuals?"
This is getting old but I will
persevere. WHAT DO THE NUMBERS SAY? How many conflicts will they have?
How will resources change do to this? What is the MAGNITUDE of this
resource shift? How will this affect the economy? In otherwords, what is
the financial bottom line on every strata of society? Where does the
money flow from this decision, because if money doesn't change its flow,
then no one will be pushing for it. Hmm, that just might be my opinion,
but possible a wise one coming from decades of observing mathematically
based solutions versus emotionally based solutions.
"What's the best way to unplug the toilet?"
Obviously asked with the purest ignorance of engineering, and thus math.
Two choices: physical or chemical.
Two concerns: financial and capability to perform the act.
I hope the
real math, the engineering of the plunger that eventually leads to
common acceptance then to common sense. Or maybe its the size of the
toilet outlet, 2 1/2" output toilets clog much, much easier than 3". But
what sane person would want to know that math when purchasing a new
toilet because they got tired of unplugging their old toilet!!!
"Math
plays little if any role in solving such problems, nor do such problems
have clear-cut right or wrong answers, demonstrable by some formula."
Well,
I guess someone that make statements like these did not get a GOOD math
education. Otherwise, they would see math applications in every single
thing they say or do. Maybe just not the math they were taught.

Addition:
I believe
my intent has been misunderstood. I do not believe that everything
SHOULD be viewed through a mathematical lens. I intimated that
everything COULD be viewed mathematically and took objection to the
article that gave several examples where the author claimed that math
was irrelevant and therefore shouldn't be worshiped. I agree it
shouldn't be worshiped. Math is not on a pedestal or should ever be, but
it is incredibly foundational. Not only to us but apparently to birds
and other mammals as they all seem to have developed the ability to
recognize and instinctually operate on small numbers. That is the area
of my research and my life's recent work. That is what I believe should
become the core of mathematics education: recognize numbers, especially
their place shapes, observe how numbers can be used,to predict the
future, and observe how meta patterns form the basis for polynomials and
calculus. What students do after that is up,to them, but they will know
that numbers can help them predict the future. (I'm hoping I rattled
the hornet's nest again.). Sweet dreams.
DR @VWBPE: The Poster Site, part 3 and more... posted 3/17/2012 In addition we are also running a continuous competition that will go on after the conference, so take a look at our sign to the right of the bar. We would appreciate having you participate. Special thanks go out to the institutions that have helped house our learning stations: University of Washington Avalumni, Boise State EdTech Island, Oregon State University Pixel Mtn., University of Oregon CLIVE, and ARVEL @CAVE Island. If you or your institution would like to host one of our learning stations, please contact UteFrenburg@gmail.com. We also offer individual and group tours and lessons of our material. DR @VWBPE: The Poster Site, part 2 The sQi3d Controller posted 3/17/2012 The sQi3d Sushi Bar may seem like just a quaint place to sit, but those placemats are not your ordinary placemats. They serve up numbers like you’ve never seen before. The sQi3d (subQuan interactive 3d controller) talks with our 3d placemats. Visitors may play with different modes: subQuan, quantity, base, shape, color. The device will speak to a specific placemat (6-A) or multiple mats if base ‘x’ is chosen. A look at our menu to the left of the bar will highlight the sQi3d’s capability. We welcome you to play and discover patterns.
The 3d base sheets start on the far left at base six and runs the length of the bamboo bar to base ten (A) on the far right. You can imagine the prim usage, so we had to disable 2d mode in addition to not displaying bases two through five. Here we have a quartic equation: 5x^{4} +6x^{3} -4x^{2} -2x +8, but don’t let me kill your synapses. Come discover for yourself. You can “see” it! DR @VWBPE: The Poster Site, part 1 posted 3/17/2012 Dream Realizations, in conjunction with ItOnlyTakes1 and CERLabs, participated in VWBPE12 in many ways. With four presentations and a very creative Poster site, we provided the audience with the ability to “see” numbers, how their “new view” applies to Algebra and beyond, and shared the interface on which Cooper Macbeth has been so diligently working. Notice the sQi3d Sushi Bar (pronounced ‘squid’) as our backdrop coinciding with this year’s Japanese theme: Be Epic! Our subtle and yet powerful programming lay hidden for only the intrepid and curious visitor. Let me give you a tour of our relaxing and “eye-opening” Poster Site.
The first view of our platform is a space for rejuvination and collaboration with our tai chi poseballs and soothing spa-like atmosphere. In one corner, you will find a small bamboo table with a blue orchid bonsai centered between two incredibly effective artifacts. To the left is what we call The Hands. The Hands is a binary counting tool that teaches color, shape, container (base), and number. This device was offered to all our session attendees on Saturday’s 3-hour Workshop. To the right is our standard Base Number Sheet (BNS). This sheet happens to be in base 6 and is controlled by a HUD or a sQi3d Controller. Above the table, on our only media prim, is our Prezi introducing subQuan and our need for it in math education, which can be found at http://prezi.com/_bjmdidoxnxp/subquan-intro/ .
Moving along the back wall, you will find information about our 501(c)(3) Dream Realizations, contact points to follow our developments and get involved with us (http://dreamrealization.ning.com/), and two screens showing our activities around SL. Don’t forget to spend some luxurious time in the spa! But let’s turn our attention now to the heart of our undertaking: The sQi3d Sushi Bar. What is Number Sense? Is it the same as number concept? Posted 2/14/2012 Thanks to Mitzi on the LinkedIn group Math, Math
Education, Math Culture for posting this question and a special thank
you to Colin McAllister for letting me know about it! Here are a few of
the responses for you to peruse:
Colin McAllister • Mitzi,
It seems to me that "number concept" is an abstract or intellectual
understanding, and that "number sense" is a skill that one applies to
perceiving and manipulating numbers, i.e. counting. The simple answer is
that they are not the same. They differ in the same way as the
dictionary definitions of "concept" and "sense" differ. A computer
programmer might use number concept when designing a program algorithm,
and number sense when checking the output of a program for obvious
errors. Henry Schaffer • My favorite example of number sense is http://www.eecs.harvard.edu/cs261/background/p180-bentley.pdf "The Back of the Envelope". Lynne Ipina • Perhaps you would be interested in the "strands" of numerical fluency from the report "Adding It Up: Helping Children to Learn Mathematics. See pages 115-117: http://www.nap.edu/openbook.php?record_id=9822&page=115 Rebecca Reiniger • Mitzi,
Sounds like you have hit the same problem that I have in investigating
the various definitions of "number sense". I have seen it also as number
instinct and quantity sense. I would love some of your research finds
where they discuss the variances. Check out the group page if you're interested in more or adding your own comment: http://www.linkedin.com/groupItem?view=&gid=33207&type=memb... Or feel free to comment here! CERLabs Learning Environment Prototype Posted 1/18/2012 Now that we are speaking at
CO12, Connecting Online Conference, Cooper has been working tirelessly
on the design and implementation of a learning environment in Second
Life. We currently have eight Universities willing to house these
rotundas where we will also advertise their programs. We hope to
greatly increase the virtual world traffic for the benefit of all
entities. Our first prototype can be found at the University of Washington: Contact us for a tour as it is still under construction. This first lesson, Place Shape vs. Place Value, will be the main topic of our presentation at CO12. You can see an explanation of this concept during the first part of our Prezi. We continually brainstorm additional lessons that take advantage of the 3D realism in Second Life. A fascinating thing about 3D lessons is the active involvement of participants in their own learning. These environments are conducive to: 1) teachers wishing to understand the concept of subQuan in order to apply it in their classrooms, 2) college students desiring to have a deeper understanding of why algebra works, or 3) anyone interested in learning how to use a virtual environment to enhance the education process. Avatars participating in the lesson receive a HUD, which allows them to interact with the self-paced lesson. Try your newfound skills and discover the shape of numbers! If you can join us at CO12, please do: WiZiQ on February 3^{rd} @ 6pm PST. Follow this link to sign up. If you would like to learn more or get involved in lesson design, please do not hesitate to notify Cooper, Anna-Marie, or me. subQuan Intro via Prezi Posted 12/14/2011 I've been working on a Prezi introduction for DR and subQuan to give viewers and idea of our direction. It is still in rough form as I need new pictures in accordance with the new BNS updates that Cooper is so diligently working on. It's quite a challenge to get everything up and running after back surgery and a root canal. Ugh! Our prayers are with you, Cooper!! Anyway, take a peek and give me some feedback about cohesiveness, understandability, and flow. Also, let me know if it induces motion sickness. I will continue to make changes and upgrades and post my revisions here to keep you up to date! Thank you in advance for your comments! 3D GameLab - The Future of Gaming Posted 8/6/2011 Learn by doing! What a concept! I think kids are interested in producing, not just consuming. I have heard some individuals say that games are only fun for a while then people/children will get bored and want to do some higher-level learning. I think that it all works together: another tool. How boring to do one activity every time, with games the versatility is so broad. I have often thought that mathematics is one of these heavy textbook driven courses: giving more information than is used at the time of student need. That is why I am feeling called into the mission of changing the paradigm of math education. I believe that by changing the focus of math in the elementary grades, we could, conceivably, have math through Algebra taught before children get to middle school. Imagine not being required to take 4 years of high school math. Not having math as a stand-alone class except as an elective. Incorporating math into all other disciplines. Imagine students with the ability to grasp estimates and have a great number sense. This is exactly what Dream Realizations is working toward and I believe that gaming is a very large part of it all. I really like the idea of games that are not just for playing, but also for creating and producing: interaction and emotion. They leave you vulnerable to brainwashing, as David Perry explained here: http://www.ted.com/talks/david_perry_on_videogames.html So, we need to be careful with content, but to be able to have a deep, emotional pull that substantiates situational, experiential learning is a powerful tool for education. This leads the educator to be careful, thorough, and thoughtful in design of games and tools used in the classroom. I’m not sure if I want to be involved in something virtual that can be classified as “better than life”. I would rather be involved in something that enhances life and makes some of it easier and more rewarding in the internal aspect. Games and their rewards are motivating for humans and being able to measure all those points of data allows for specified reward system to build and engage learners.

Multiple long- and short-term aims (calibrated slices) 3. Rewards for effort (credit for trying, too) 4. Rapid, frequent, clear feedback (learn the lesson and move on) 5. An element of uncertainty (this lights the brain up – transforms the levels of engagement - Dopamine) 6. Windows of enhanced engagement (memory & confidence) 7. Other people! Business – recycling and education (real time energy meters) Education – grand continuity (small tasks and calculated randomness with rewards) Government – financial rewards to remove obesity and more ENGAGEMENT – individual & collective Hello all! Posted 12/3/2010 Welcome to Dream Realizations! We are looking forward to some interesting conversations regarding Math Visualization! I will be posting some research abstracts in the future to talk about and disseminate as to how they relate to subQuanning and I would love your opinions. Have a blessed day! |

Can some students not learn Algebra? posted 11/26/2011 by Rebecca Dan Meyer posted an interesting and highly commented on blog post this week: http://bit.ly/sK5VhY . "Last April, fourteen of Palo Alto High School's twenty math teachers petitioned their school board [pdf] against raising graduation requirements to include Algebra II:
Many of the comments to this blog post talk about the usefulness of Algebra and specifically Algebra II. As it is taught currently, I would tend to agree that's it's abstractness is not necessarily used on a daily basis. I do, though, believe that if algebra were more easily understood, it could be applied in more situations in order to increase successful outcomes. This is where DR comes in! We are needed now more than ever. Brain Calisthenics for Abstract Ideas posted 6/10/2011 by Rebecca I read a fantastic NYTimes article this week: http://www.nytimes.com/2011/06/07/health/07learn.html?scp=1&sq=...
It talks about how our intuition is underused and that the human eye can recognize patterns quickly in our subconscious even before we understand it ourselves: perceptual training. Quoted studies include: 1) Matching equations to graphs (quickly) 2) Liking a better deck of cards when gambling 3) Distinguishing painting styles [I like this one the best!]* 4) Fraction building (quickly - repetition) 5) Slime-mold for global warming experiment
Patterns, patterns, patterns....they are what life is all about. It is so nice to find research that is, yet again, substantiating the direction of Dream Realizations. *3) Distinguishing painting styles [I like this one the best!] Seeing multiple painting styles instead of just concentrating on one artist alone allows the eye to pick up the pattern naturally. I relate this to base systems: if we teach all base systems, then the eye can pick up the patterns for itself and focus is off the single painter (base 10). The world has opened up with possibilities!!
Definitely worth the read! DR is developing a public grant to bring subQuan to the iPad posted 4/9/2011 by Cooper I believe the touch interface will enable the creation of an intuitive and very real graphical user interface (GUI). This GUI allows us to build seamless transitions in the user input screen based on the level of knowledge and special needs of the user. This is ideal for young students learning numerical values, words, and symbols. I also believe this might provide a solution to a problem dyslexics have with numbers. Replies to This Discussion
Math Visualization posted 12/4/2010 by Rebecca What does "math visualization" conjure up in your mind? Is it only physical manipulatives? Or is it drawing out a word problem into pictures? We regularly step back from math and try to visualize its usage, but have we stepped back far enough to see the patterns? Just a few random thoughts to start off a Saturday morning. Happy weekending, all! Replies to This Discussion
Brains vs. Computers posted 12/4/2012 by Rebecca The brain can be compared to computer hardware. Graphics Processing Units (GPUs) have become more widely useful in computer and video processing. “Using GPUs … gives the computer a processing capacity that competes with supercomputers over twice its size” (http://www.theinquirer.net/inquirer/news/1563044/supercomputer-gpu-... , paragraph 2). The vector (3D) graphics implementation in computer hardware has increased capacity and facilitated a greater speed in computing. "GPUs are redefining high performance computing," said Jen-Hsun Huang, president and CEO of NVIDIA. "With the Tianhe-1A, GPUs now power two of the top three fastest computers in the world today. These GPU supercomputers are essential tools for scientists looking to turbocharge their rate of discovery" (http://pressroom.nvidia.com/easyi/customrel.do?easyirid=A0D622CE9F5... , paragraph 7). Designers are finding in the computer industry that graphics give computers a stronger foundation for processing. Dehaene (Jossey-Bass, 2008) describes a major upheaval in the mental arithmetic system during the preschool years when “progressing in math means storing a wealth of numerical knowledge in memory” (p. 281). This storage of numbers in the brain is different than the storage of vocabulary. Verbal memory can be powerful with its cohesiveness and connectedness. Humans possess associative brains; we can open a memory from a vague recollection, something computers have yet to master, which makes learning vocabulary easier than learning the multiplication table. Each calculation within the multiplication table hangs independent of the other multiples when memorizing and that’s where the brain’s associative nature fumbles and numbers jumble inside our head, resulting in mistaken memories, which correlates to wrong answers. So, why are we still relying on this outdated practice of memorization? Jossey-Bass, I. (2008). The Jossey-Bass reader on the brain and learning. San Francisco: Jossey-Bass. Virtual Worlds and Mathematics posted 12/4/2010 by Rebecca How can we incorporate what has been done in the past with virtual worlds, how the brain learns, and using this 3-D environment to tap into the instincts with which individuals were born and see mathematics as we have never seen it before: patterns unrecognizable without the advancement of technology? |
