TED Videos with Computational Thinking

Cross posted on the Exploring Computational Thinking Forum:

A colleague of mine wanted to understand more about one of the projects I am working on at Google. He is an Artist and felt that Computational Thinking was something he used everyday but still a little unsure. I decided to send him a bunch of TED videos showing how much we use and rely upon Computational Thinking everyday.

When I began to look through the TED Videos, I was amazed at how many of them relate to computational thinking in some way or another and that is why these videos amaze us. TED videos showcase people doing extraordinary things and seeing the possibilities when we look at the big picture.

See if you can find the 4 aspects of Computational Thinking in each video:

  1. Decomposition - Breaking down the data
  2. Finding the patterns in the data
  3. Generalizing your findings and discovering the big idea
  4. Turning them into a set of instructions that others can reproduce

Whether you are an artist, scientist, Engineer at Google, or student, Computational Thinking is present and makes possible the world we see. I hope these videos are equally useful to you in explaining to others what Computational Thinking is:

How Algorithms Shape Our World - If you thought Algorithms were only used by computer scientists, think again.

The Best Stats You've Ever Seen - Hans Rosling shows how big data and patterns can tell humanity's story. Al Gore did something similar with big data to show humanity's impact upon the planet.

Making a Car for the Blind - You may have heard of Google's Autonomous Car but what about a car that allows the blind to drive?

Synthetic Life - Craig Venter started the human genome project and they used that information to make the ultimate algorithm, a synthetic cell

What We Learned from 5 Million Books - Hilarious as well as inspiring as we see what happens when we start looking for patterns in our books. This is the power behind Google Translate.

Nature in Architecture - Many of our most useful innovations have come from emulating nature.

Teaching Kids Real Math with Computers - In this viral video, Conrad Wolfram says that math > calculation and with Computational Thinking we can teach students far more than we ever thought.

Computing a Theory of Everything - Stephen Wolfram, shows how knowledge is related and can be used to better understand the universe.

The End of Theory - Not a video, but a revealing article about why students need to learn how to work with data and statistical analysis.

Lets All Share Our Awesome Math

So as I said in a previous post, Spring Break is my chance to take a moment to reflect and see what I can do better. Thanks to all of you sending me articles and my network of resources, I have had no shortage!

One theme that mysteriously keeps coming to my attention is the lack of richness in our curriculum. In one of BrokenAirplane's earliest posts, I encouraged all of us to aim for the highest level of application as the end result of our student's learning. Now in the last couple of weeks, I am seeing great posts from thoughtful writers about how shallow our textbooks and assignments are.

In this one, Frank speaks about how the Khan Academy is actually reinforcing our shallow model of education. I agree with his point if teachers are allowing these "tools" to be the complete math curriculum. It would be like going to a cooking class and spending weeks learning about the mixer, the oven, baking soda, etc. and never actually making a cake.

While on the other hand, I teach at a school which does not track and I have 9th grade students who are ready for Trigonometry and others who never understood Elementary Math. Using ALEKS and Khan Academy occasionally (<20% of class) has dramatically improved their confidence in their skills and participation in class discussions.

Another source of this mathematical meme came from Republic of Math and describes the difference between contrived and real problems. Contrived problems are a poor attempt to compel the student to care when the only purpose of the word problem was to wrap a story around a calculation problem. Kirby Urner has said before that we need to tell better and bigger stories and we will find that math is a part of that bigger story without having to make some contrived reason up, and just a couple of days ago, Dan Meyer spoke about the need for strong narrative to drive critical thinking.

The other part that keeps rattling off in my mind comes from my "Is Calculating Math?" post about Conrad Wolfram's exhortation that we stop the trend of 80% class time teaching/learning to calculate. I agree 100% and yet I am now finding myself overwhelmed. I am asking you out there for help at getting better at mathematical modeling. If you haven't watched the TED Talk, check it out here.


According to the Mathematics for Teaching Blog, mathematical modeling breaks down into 4 categories:

Empirical modeling involves examining data related to the problem with a view of formulating or constructing a mathematical relationship between the variables in the problem using the available data.
Simulation modeling involve the use of a computer program or some technological tool to generate a scenario based on a set of rules. These rules arise from an interpretation of how a certain process is supposed to evolve or progress.
Deterministic modeling in general involve the use of equation or set of equations to model or predict the outcome of an event or the value of a quantity.
Stochastic modeling takes deterministic modeling one further step. In stochastic models, randomness and probabilities of events happening are taken into account when the equations are formulated. The reason behind this is the fact that events take place with some probability rather than with certainty. This kind of modeling is very popular in business and marketing.
All of these are applications of mathematical knowledge and I want my students to do it more than they are. The Internet is based upon the idea of sharing and not reinventing the wheel so if you have had success in your classroom with Challenge Problems, projects, or any other application of these ideas that you think would be suitable for 9th grade math students I would greatly appreciate it.
I am aware of the great resources out there from Dan Meyer, Ben Rimes, ASU's modeling instruction and the like. As I said, I am not so much concerned about the pedagogy as the questions. At my school we have teams of humanities/math teachers and I yearn for my students to talk about math class the way they do after leaving my partner's class. Sure they talk about the cool thing they just did with Arduino or Python but I want to help them see the bigger picture and allow puzzles and math to be a source of fun and thought for them not just frustration.

I am tired of looking through textbooks and sifting through websites hoping for great math. There is nothing I like more than walking around and having a great idea for a project or problem come to me, but I would love more. Basically, I am asking for your "Awesome Awesomeness" as one of my colleague put it. Please share it in the comments or tweet it using the hashtag #AwesomeMath.

Get Your Students Thirsty for Math

Many of you read the Is Calculating Math? post last week and are now considering what can you do to bring Math back into your classroom. There are so many resources out there to get students thinking mathematically. What does it mean to think Mathematically? Every student is different and we need to take that into account. Is our goal just to teach a canon of concepts or to inspire students to look at the world with the eyes of an artist? I think it is a little of both.

Howard Gardner's Theory of Multiple Intelligences refers to 9 various intelligences which describe a student's strengths and preferred method of learning. If we look at the logical-mathematical sphere of intelligence it refers to quote:

Less emphasis on traditional mathematical ability and more on reasoning capabilities, abstract patterns of recognition, scientific thinking and investigation, and the ability to perform complex calculations.

I believe all students are capable of enjoying these aspects of life and our universe and so in addition to the standard curriculum, wherever possible, I provide my students opportunities to explore.

One great resource that I have come across is James Tanton. His website provides a lot of great resources and ideas about math and how to make concepts more easily understood. Many teachers do not know the reasons behind why they do certain things in math and this can frustrate students when they want to understand. Mr. Tanton's resources and books are more conversational and geared towards students and teachers reading them for enjoyment and explanation. For example, here is a great free guide and resource about Quadratics.

I really enjoy using Math without Words and examples from Solve This. The post that inspired me to  check out these resources came from this Math Mama Writes blog post. In the post you can see some examples and see why my students and I were so excited about it. Every time I use one of these resources I seem to hook one more student into realizing that math is fun. The coveted, "Wow, this is really interesting" to the student who is working on a Kakuro puzzle you gave them after school for fun.

We can have the best teachers in the world, but if the students are not enjoying themselves then they will not be receptive to learning. In We Make The Road by Walking, Myles Horton is asked to comment on education as related to the quote, "you can lead a horse down to water, but you cannot make him drink." His response was:


This is a problem they deal with in academia by hitting the horse over the head and beating on him till they force his nose in the tub, and just to keep the blows from continuing, he'll try to drink. My system is to make him thirsty, so he'll volunteer to drink.


If you can get your students thirsty for math, they will be able to learn anything because they have motivation.


Updated: After writing this post, I received an email from BachelorsDegree.org with a link about 20 Incredible Math Ted Talks some of which I had seen before and some I had not but they are a really good list. It is important to keep learning all of the time so you can answer student's questions. Not just the ones about how to solve problems, but why and what makes math interesting.

Collaborative Learning Strategies in the Digital Age

Every teacher at some point will arrange the classroom into groups either for a specific project, ease of walking around, or perhaps because they believe they will help each other. A few days later many of these classrooms will revert to a more individualized seating chart. Why? It could be noise of students talking to each other, copying each other's work, or not getting any work done at all.

There has never been a better time for you to move their desks back together. You might need to make a couple more adjustments to your classroom though to make it truly effective.

Let's state the obvious, students want to sit next to each other. Stated even more generally, humans are social creatures. We as educators love to meet in the lounge or department meetings and catch up and talk even if it isn't always about education. I believe that if the students already have motivation and energy to do something we should not fight it but harness it.

When students are sitting next to each other they are going to talk, the question is what will they talk about? Well if your assignment is compelling and worthy of their time then they will talk about that. Maybe not the entire time but we ask our students to work for 8-10 hours straight. This flies in the face of all wisdom about productivity. Those of us who are great at getting things done know that it can't be all work and no play.

You might say, well some topics are boring and simply must be learned and there is no way to make it otherwise. I say you are not being creative enough. Can the topic be placed into a social context like a game or involve peer review? Yesterday my students played the game battleship on graph paper to review/learn coordinate graphing, and I heard so many of the coveted "Ohhh now I get it" and there wasn't a student not playing/learning (and no I do not teach a magical class of students who love any and all things math).

So if you have a compelling assignment and are willing to accept that they will not be 100% efficient (no one truly is), then lets consider the benefits of putting them in a collaborative setup:

Peer Feedback and Instruction: If you have instituted a culture of collaboration and team success, then your students will look at each others work and give them ideas on how to refine their work. Most useful is when they start to help each other to understand their work. Students can speak to each other and explain things much more efficiently and effectively than those outside their circle can. If you constantly are encouraging your students to help each other to understand (and not cheat them by giving them the answer) then you will quite simply be blown away by how much students will want to help each other.

This also allows you to help more people because when you have explained something to someone else, you can ask them to help the other person with the same question. Every educator knows that teaching a concept to someone else helps them understand the concept even more. Give that gift to your students as well. As they struggle to coherently explain it to someone else they create deeper understanding. I tell both students that if either of them still have questions they can come back and ask me. You will find overtime that even those who are not typically well versed in math will eventually come around and become better at asking for help and giving help at what they do understand.

Initially students can be reticent to ask or give help to each other. This is due to years of training the students to be solely reliant upon the teacher. When I have given instructions to the students, placed them on my website for later reference, and/or placed them on the whiteboard. I ask the students for 2-3 questions as a class(and then wait until they ask them, sometimes they need some time to think about it). Then we begin group work.

When the students want to ask me questions, I will redirect them to students. "Have you asked everyone around you?" If they answer yes, then I have 3 or 4 students to work with, otherwise I move onto another student and only answer the questions that the students can't answer. This can be painful for students and teachers to do initially but it pays off greatly and will allow you to spend more time with struggling students or with those who need an additional challenge.

Social Innovation: When you are in the presence of thoughtful colleagues great ideas emerge. When students are working on projects or assignments and are in a creative mindset, it is an exciting environment to be in. This culture that is so willing to explore and try new things can take your curriculum to new heights. This is especially useful when my students are programming in Python. Some great side collaboration projects in the class and outside have emerged out of this.

21st Century Skills: Report after report from business leaders says that the two skills they wish their incoming employees had were the ability to think creatively (outside-the-box) and collaborate well with others. Collaboration  is also listed as one of the 7 survival skills in Tony Wagner's The Global Achievement Gap.  Please do not deny your students the opportunity to grow in this critical area. Using effective social skills to communicate ideas and learn is just as important if not more than any one thing you will teach them.


Digital Natives: A term coined by Marc Prensky, it describes those who have grown up in a world with YouTube, Google, Smartphones, and everything else that provides instant information. Just as teachers in the past needed to adapt their teaching style to incorporate other innovations (e.g. television, radio, chalkboards, books) we would do well to observe their natural learning state and utilize the power inherent in it.

Students from this generation and those of us who have migrated to this type of thinking, use the vast information of the Internet to learn skills and understand. What brought about "Web 2.0" was the increase in video content but also the ability to share information with others. Where the Internet used to be a digital repository, it has now become a living breathing community, truly a World Wide Web.

My students are often sharing ideas on others blogs and finding people from all over the world to collaborate with. Through free communication tools, they have found experts willing to work with them and bounce ideas back and forth. This was simply not a feasible option for them a few years ago. Bring in an author, expert, community member through video conference for free and see how it will change all that you do. Make sure that you have coaching sessions about how to professionally meet and speak with others as this tends to be a skill that students need improvement.

If you can find and encourage opportunities for your students to use this to learn traditional content (e.g. Personal Learning Networks - PLNs, Instructables, YouTube Tutorials, Khan Academy) your students might be more willing to "buy-in".



My experimenting with Social Learning began a couple of years ago when I asked students to work together on an SAT Math study packet. After they finished, I asked them to honestly share. Their responses included that they felt like they had understood it better than when they had heard it in a lecture (and their scores reflected this), they also admitted that the chances of them "cheating" and simply getting the answer was likely.

When we discussed this, I explained to them that the goal of these group activities is not simply to get the "A" but to learn and understand. I remind them that while they might have good short term results, "no one cheats their way through medical school". A statement that may not be true, but it drives home the point that at some point they will be asked to demonstrate their knowledge on their own and it is in their best interests to not take the shortcut.

I am not saying that students should only learn via the Internet or games, these are just some ideas for encouraging social exchange of information, and yes I do assess individually via tests, so while individual learning is the goal, you will find that the learning occurs will just as much and creates an environment electric with discovery and ideas.

If you need further convincing of how powerfully this can transform your classroom, I suggest you watch this TED Talk. Sugata Mitra is showing the world the power of each of your students. Below that is the Dean of Pixar Univerity (yes that Pixar) about the need for students and adults to collaborate.





How to Curb Plagiarism in Your Classroom

If our goal is to teach, our students is to learn, and our primary method of assessing that is through assignments and tests; then the highest concern is that of making sure each student has done their own work.

Before we discuss plagiarism, we should mention the term Digital Native. Digital Native is the name many have given the generation of students who have grown up their entire lives with Mobile Phones,Google, YouTube, Torrent Sharing, etc. Usually, the term is pejorative, saying that these students have no social skills, ability to think deeply, or respect for copyright.

All of these are true/false in varying degrees just as much as it would be for any other person on Earth. Stereotypes get us nowhere.

Plagiarism is considered a growing problem within schools because of the pervasiveness of the Internet. Sharing information and  files is so easy that students can find the definition of a word faster than they can say it.

I believe that plagiarism can be curbed if not eliminated from the classroom in a few ways. 
  • Plagiarism Checkers - There are free and paid versions of these. They allow you to cut and paste or upload a file to check it against the Internet to see if anyone has already used it. The problem with this is if someone from your own class wants to share with another student the online checker will fail. Basically, it will prevent them from plagiarizing sources but not other students. Additionally, this will only work for written work and not math for example. However, it does have it's place. Google will help you find the one that is right for you.
  •  Blooms Taxonomy - In a previous post, I suggested you reflect upon your curriculum and where it is on the Bloom's Taxonomy pyramid. If you are asking your students to recall a definition or equation then you are creating an environment where they simply need to ask a friend or Google for the answer. While you might think that Googling answers is a mentality that needs to be squashed. My challenge remains for you to assess the students through application and creation. It is pretty difficult to copy when each is expected to provide their own thoughts. 
    • For those in math, I recommend ALEKS and Accelerated Math. Personally I like ALEKS more because it explains and uses less paper. They both will create differentiated work for students to work at their own pace as well as have different copies of the assignment. If the thought of that creates fear from a grading perspective, fear not for both of these programs will grade them for you.
  • Copyright Education - Even veteran teachers are unclear about what constitutes fair use. Teaching students how to cite and when and what is appropriate for each assignment will go a long way. I would imagine this article would be true of any age, but it drives home the importance of clarifying the fine line. I also recommend this resource as it clarifies the law.
I always tell my students that, "No one cheats their way through Medical School". You can rest easy, that if they are cheating now, it will eventually catch up with them. Additionally I will quote Seymour Papert who pioneered Technology in the Classroom decades ago saying, "In the future, people will be hired not for what they  know, but what they are able to find."

Finally, I leave you with this funny and uplifting TED talk.

Using Bloom's Taxonomy to Influence Curriculum

Do you remember learning Blooms Taxonomy when studying to be a teacher? When it comes to the cognitive domain the theory is that Memorization is the foundation of learning but the least likely to be "sticky" and be retained (thanks to Ted for the phrase). The next is understanding, as in Why the Civil War ended as it did as opposed to knowing the dates and states in the North and the South. Or how increasing the height a ball is dropped from will increase its final velocity.

Application is using this information in a real world situation. Every week thousands of students conduct some sort of Lab in science where they recreate a famous experiment and if the intended data and results are collected, the student receives full credit.

The highest level of learning according to Bloom's Taxonomy involves Analyzing, Evaluation, and Synthesis (creation)....let that set in for a second.

We have state and federal standards that we are expected to teach and therefore the students to learn. If you look at those standards, they involve some form of memorization (identify, know) or understanding (explain, describe). Why? Because the best a standardized test can assess by its very nature is memorized facts (multiple choice) and understanding  (extended response/essay).

With so much to teach, so little time, and so much riding on the student's score on these High Stakes Exams, it is no wonder that our students are doing poorly according to International Criterion. We have set the bar at the minimum and even if our students retain everything the best they can hope for is good test scores.

When they leave, will they be able to use that knowledge? Do they even care about using that information anymore? Facts and trivia are great for winning Jeopardy but they fail at inspiring excitement and interest.

As we plan this year fellow teachers, I ask that you consider how you might teach to the higher levels of Bloom's Taxonomy. Application, Evaluation, and Synthesis. You would be surprised how much more students will want to learn and how much more they will have learned, when they have built, debated, repurposed, drawn, animated, ignited, and every other word that when uttered to a child evokes a smile.

Is it messy? Yes. Is it hard to assess? Not really. It just doesn't fall under the choices of A,B,C,D. Will you cover less? Perhaps a little, but think of how far a little depth would go. If we are teaching them to synthesize and apply, then they will certainly be able to do so on a test question that they do not understand.

The test makers call it an educated guess, we call it critical thinking.

Please, do not be too hard on yourself if you cannot immediately figure out a way to do this. Any little steps you can take will lead to bigger ones. For some inspiration I recommend the following:

Watch Gever Tulley as he speaks about his Tinkering School where 10 year olds create with power tools.


Imagine what your kids could do if given the opportunity to freely express their creative energy. Tulley has a book out with even more ideas: Fifty Dangerous Things (You Should Let Your Children Do)

Watch Sir Ken Robinson's comedic take on how schools are killing creativity (and how you can stop it). Thanks Marisol for showing this to our staff today!


Finally, if you did not catch my first post about it. Watch Waiting for Superman on September 24th for a compelling tale about our school system and what we can do about it.

Teachers, we have an incredible opportunity to inspire and excite our population. While it may seem daunting, it will result in more fun and learning than ever before. Please be mindful as you plan your curriculum to encourage application, analyzing, evaluation, and creativity.

Any thoughts on the matter? Agree, disagree? What prevents us from doing this everyday and how can we overcome these obstacles?
