New graphing calculator lets students plot on top of real-world images

Media_httpwwweclassro_bcfik

Texas Instruments (TI) graphing calculators are king in the math classroom. I have no statistics - no hard evidence to prove that beyond experience and anecdotal evidence. Indeed I cannot think of any math teacher or math classroom I've ever known to promote the use of anything but TI.

However, Casio has taken a huge jump in the real-world connection between math instruction and the world we live in with their PRIZM graphing calculators and their Picture Plot technology. The expectation is that students using this device under proper guidance and facilitation by an instructor would gain a greater appreciation for the engineering behind structures, both natural and man-made. This product seems as though it would be a real benefit to good math students on the fence regarding their possible futures in mathematics-related fields.

A side note here is the proper education of the principles of photographic arts - framing, squaring, lighting, etc. A bad picture that is poorly aligned is not going to provide the results desired. For instance, the graphic included in this post, taken from the source article (eclassroomnews.com) shows a steel trestle (bridge) spanning a gorge. The photo shows the plots of the parabolic structure, but the photo used was not squared up, therefore skewing the perceived intention of the technology as it relates to math. There are lessons there, but I wonder about the impact of sloppy photography on good math.

I wonder how the math tech giant TI will respond to this device. I would hope to see an iPad TI graphing calculator app with these capabilities...

Our Digital Kids

Below is an excerpt from a book written in 2010 by Jason Ohler (jasonohler.com) titled Digital Community, Digital Citizen. It is a still-timely reflection on the disparity between the generation in power and the generation in our schools. It's a tragedy that the questions he phrases below even have to be considered, really. Read on and consider how things could be different if those that participated in creating this tech-infused world cared less of themselves and more of posterity.

Preamble

Our Choice for Our Children - Two Lives or One

We have a fundamental question to address with regards to educating our Digital Age children. How we answer this question will determine how we plan for and implement education in the broadest sense for many years to come. In its simplest form, the question is, Should we consider students to have two lives or one?

Allow me to restate this question with a bit more detail: Should we consider students to have two separate lives—a relatively digital free life at school and a digitally saturated life away from school—or should we consider them to have one life that integrates their lives as students and digital citizens?

The “two lives” perspective contends that our students should live a traditional educational life at school, much like their parents did, and a second, digital life outside school. It says that the technology that kids use is too expensive, problematic, or distracting to integrate into teaching and learning. It says that issues concerning the personal, social, and environmental impacts of living a digital, technological lifestyle are tangential to a school curriculum. Above all, it says that kids will have to figure out how to navigate the digital world beyond school on their own and puzzle through issues of cyber safety, technological responsibility, and digital citizenship without the help of the educational system.

On the other hand, the one life perspective says it is time to help students blend their two lives into an integrated, meaningful approach to living in the digital age. It says that if schools don’t make it their primary mission to help students understand not only how to use technology but also when and why, then we have no right to expect our children to grow up to be the citizens we want them to be and that the world needs them to be. It says that if we don’t help our digital kids balance personal empowerment with a sense of community responsibility, then future generations will inherit a world that does not represent anyone’s dream of what is best for humanity. It says that if we don’t understand that schools are exactly the place for kids to learn how to use technology not only effectively and creatively but also responsibly and wisely, then heaven help us all.

Jason provides a relevant decision-making reflection based on where we've come regarding the gap between two worlds - one world run by an older generation who have learned to live with increasing digital demands as adults, and another world whose entire lifetime exists within the parameters of a digital society, knowing only mobile devices, mp3s, Facebook, and YouTube. Where do the two worlds come to terms? Why does one world have to submit and conform to the other? What if the balance of power were different?

 

How does this shape your perspective as you enter the 2012-2013 school year?
