What does it take to teach with technology?
After spending the last 5 months training teachers on how to use technology in the classroom, I've been able to come to some conclusions on the subject. I'm not the first to say it, but it really is true that it isn't about the technology. It's about the teacher.
Teachers have gotten by just fine with a single piece of chalk for a long time. That's because it wasn't the chalk that was teaching. Sure, there are those book things also, but with technology we can provide instruction in ways we weren't previously able to. Think of it as going from a standard box of crayons with 5 colors to a jumbo box of 64 with a sharpener. Wow, think of the possibilities! Problem is, even though you have a palette of the rainbow before you, it still depends on how good you can color.
So what does it take to teach with technology? It takes effort on the teacher's part. You need to educate yourself on what resources are available and how to use them. Your goal shouldn't be to plug a computer into a student. Each tool and resource have their own benefits and limits, so get acquainted with them. Decide if you want to color the sky with Cerulean or Blue Gray. You have your standards to guide you, but you don't have to stay in between the lines. You have infinite resources and solutions to choose from so you better get started.
You have a lot of ways to present the information, but you still need to think about the information itself. If a lesson is composed poorly, technology isn't going to save it. Think about your instructional goals and then choose the best resource to accomplish it. You shouldn't be using technology for the sake of technology alone. On the other hand, why do you have that beautiful box of crayons if you're not going to take it out? Is that interactive whiteboard collecting dust in the corner because it isn't useful or because you haven't found a use for it?
Be prepared for class. Sometimes you find a crayon in the box that is broken. You need to have a back up plan for those times when the Internet is down or a bulb is blown. If you have trouble, you can always ask for help from the teacher across the hall, only now you have thousands of teachers across the hall of cyberspace to get advice. Become active in a social network to build upon your professional development. This is where you'll get ideas and perhaps you can help others as well.
If we are asking our students to be creative and innovative, then it makes sense that we should expect the same from the teachers. Unlike your coloring artwork, this doesn't come naturally. You need to look for the resources to use and assemble them into your instruction. The possibilities are countless so the more informed you are the easier it will be to find the right crayon for your creation.
There are very few limits. If you were restricting yourself to teaching from a textbook before, then you had confined your students to that material. Would you want to go through school with just 5 colors of crayon? Google the words "water cycle" and you get over 23 million choices to explore. Look it up in the back of the book and it will say "p.54". Furthermore, an additional benefit of ed tech is that a wider scope of thinking skills can be addressed more easily. Collaboration, improved problem solving skills, and creativity are common byproducts. Most textbooks aim low in Bloom's Taxonomy, but then again, this depends on the teacher.
If this sounds like a lifestyle change then I guess it is. You can get by with what you've been doing and save yourself the additional time and effort this requires. But if you're like me, you'll find a renewed sense of purpose and energy in your instruction. The common thread to all of this was that it wasn't the piece of chalk or the crayon or even the bulk of technology making the decisions. It isn't the technology that improves instruction, it's what the teacher does with it.

The Path of Khan
Kirk: Khan... Khan, you've got Genesis, but you don't have me. You were going to kill me, Khan. You're going to have to come down here. You're going to have to come down here! Khan: I've done far worse than kill you, Admiral. I've hurt you. And I wish to go on hurting you. I shall leave you as you left me, as you left her; marooned for all eternity in the center of a dead planet... buried alive! Buried alive...!
Kirk: KHAAANNNN!
Perhaps it isn't quite this dramatic, but while some math educators embrace Khan Academy - others discount its influence. Of all the disciplines, I think math instructors are known as the most traditional. Upon closer look, Salman Khan's instructional approach isn't that different from what you would find in the classroom setting. Instead of a chalk or whiteboard, he uses a Smooth Draw writing pad with a black background. His diagrams and notes are all done by hand in different fluorescent colors. There are presentation tools available that are much better than his crude script. He is clearly a remarkably intelligent individual but what is it that makes his work stand out?
It's the technology - or rather, how it is used. The origin of Khan's tutorials came from his desire to help relatives and friends more efficiently, so he posted them on YouTube. Now he could create the tutorials when he had the time and his students could view them when they wanted. The online distribution alone provides an individualized instruction through its convenience.
Online videos can not only be shared, but they can be paused, downloaded, and linked to. Perhaps the college professor doesn't have the freshman's full attention in math class. The student may be tired, doodling cartoons, or thinking about the girl across the room. With Khan as his instructor, he can watch the video later. He can stop it to answer the phone, and he can replay it as many times as he needs to until he understands the epsilon delta limit.
The other thing that Salman Khan provides with technology is a vast catalog of topics in different subject areas. Enter a search term and you should find a video or several videos on the concept. Having the familiarity of the same instructor helps as well, I think, or perhaps he provides a different instructional viewpoint from what is found in the classroom. He has said that he envisions his teachings as a 1:1 experience and this comes through in the videos also. Technology has provided millions of students their own personal tutor.
What I hope Khan's greatest legacy is that he has created the influence necessary to force textbook publishers to digitize. Some math professors have decided to go without textbooks, and rely on Khan Academy to supplement their instruction. The technology has existed for some time, so perhaps it is only the profit margin that has prevented a widespread adoption of this. Khan Academy proves that valuable instruction can be provided globally in a cost efficient manner, conveniently with technology.

Stormy Weather
Living on Guam for the past 22 years has exposed me to over 15 major typhoons- as they're called in this part of the world. I've been through three Super Typhoons: Yuri, Paka, and Pongsonga. A super typhoon has maximum sustained winds of 150mph or greater, comparable to a category 5 hurricane.
It's been almost 10 years since we had our last typhoon. I don't know how long our luck will last but we'll be ready for it. Guam is situated in a convergence region so it has seen many typhoons in its history. Most of our structures are built out of concrete because anything less gets torn apart. Guam doesn't have many tall trees for the same reason. But with the extended lull in activity the island's vegetation has had a long holiday. I'm sure the next typhoon that comes along will cause a big mess in this regard.
The first lesson I made for Real World Math was the Typhoon Project. Using Google Earth as a typhoon tracker was an obvious choice when I first saw it. I saw it as an interactive map of a weather event. I'm sure I wasn't the first person to use a mapping graphic in that way, but it seemed original to me back in 2007. Now I see similar graphics for Hurricane Irene in all of the news' sites I've been reading. The National Weather Service has a kmz generator which, as I understand it, can create radar overlays for Google Earth. I haven't tried it yet so let me know what you think.

Great tip for editing placemarks
Thank you Aaron Slutsky for this gem. This is a quick and easy way to format images, videos, and text for your Google Earth placemarks. Can't wait to see how it handles text and color formatting.

Professor Morris Kline revisited
Kline was professor of mathematics at NYU, and from the 1950's-70's he was a rebellious voice in higher education. He expressed strong beliefs that the math curricula was misguided and ineffectual, taking particular aim at the New Math of his time. What I found so striking about his words was that his criticisms seemed just as relevant today as they did half a century ago. There are many of his views I could share with you but for this post I will select one.
Professor Kline believed that perhaps the greatest failing in math education occurred when it was divorced from the physical sciences. The date of this event may be hard to determine, but it probably occurred when a publisher created a textbook entitled Algebra and another Chemistry. He observed that many of the great mathematical minds of history were individuals who studied science; Descartes, Newton, and Gauss, to name a few. Throughout history, mathematics was the means in which scientific observations and deductions were made, but somewhere along the way formal education separated them into distinct subjects of study. Mathematics became a separate field of inquiry.
Kline felt that the failure of math education was not the fault of the student but of the material they were learning. Without science, or a connection to the physical world, math had lost its purpose. Learning mathematics for the "beauty of math" or the goal of learning more purposeless material would not benefit the majority of students.
What should we teach? We want material that will provide motivation, sustain the interest of the student, exhibit the methods of the operation peculiar to mathematics, and demonstrate the chief values of mathematics. I believe that the answer is to tie mathematics closely to the study of the physical world. I do not mean that mathematics should be buried in some corner of a physical science course but rather that we should motivate interpret, and apply mathematics through fundamental physical problems and of course include wherever possible the broader implications, largely cultural, of what mathematics has accomplished. Mathematics derives from the study of nature and is valuable mainly because of what it returns to nature. - Kline 1955
If you are familiar with my site, then you can see how I took Professor Kline's words to heart. I have tried make connections from math to the physical world so that students can see how concepts are applied. Many of RWM's activities are suggested as cross-curricular content for science; perhaps there should be more. What I would suggest to you is that you find a way to reunite the disciplines this year in some way. Talk to your fellow teachers and try to make correlations in your instruction. Show the students how ideas and knowledge are related so that they can realize their learning has purpose.
