I’ve been thinking a lot about the usefulness of educational technology lately, and I don’t mean to belabour the topic. But this is an interesting, if very unscientific, discussion from Jerry Brodkey writing in Larry Cuban’s blog:
A front page New York Times article on January 20, 2010 was headlined: “If Your Kids Are Awake, They’re Probably Online”. The article details the results of a new study from the Kaiser Family Foundation that the typical 8 to 18 year-old spends more than 7.5 hours a day on electronics, plus another 1.5 hour texting and another half an hour on the cell phone. Students are immersed in their electronic world.
Many schools are integrating more and more technology into the curriculum. At the school where I teach, many teachers are switching to “Smart Boards”, a sophisticated piece of technology that looks like a white board but is actually linked to a computer and the Internet. Our school district has invested heavily in technology and the trend is exploding upwards.
As a veteran teacher, the trend bothers me. In my opinion, what should happen at schools, what can makes school valuable and unique, is to provide young people experiences they can’t get anywhere else. Instead of more technology, let’s use less. Instead of emphasizing technology that is often expensive and soon outdated, perhaps schools can take a different, newer (really older) approach.
Schools offer teachers and students an opportunity to do what is almost never done in society. In schools we can gather together a group of twenty to thirty people and have them listen, discuss, analyze, and share differing points of view. Schools provide a rare chance to read, debate, write, and quietly think. We don’t need expensive technology to learn how to ask excellent questions, articulate ideas, and be forced to defend our thoughts.
School hours are precious. My students and I need to learn and consider and develop together. This is what makes my students’ and my school experiences unique. This is what makes my calculus class in room D-10 at Menlo-Atherton High School different than a calculus class students could easily take online. In the classroom the students interact with me and with each other. My students see what happens when people are frustrated, or tired, or thinking creatively. They see what happens when people laugh together, learn together, are confused together. They spend real time with friends and individuals who are like them, and also different than them. They listen to me and to each other, they ask questions, they have to communicate clearly in a real setting. They respond directly to me and to each other and see the effects of their words, the power of their tone of voice, the inflection of a comment or question.
Technology can, of course, do amazing things. Any tool can be used properly or improperly. Unfortunately, with devices like Smart Boards, images come and go, and the teacher is often looking at a computer screen for part of the class. Smart Boards and similar technologies reinforce the idea that knowledge resides in things. We don’t need Smart Boards, we need smart people. Answers to all questions do not reside in the Internet, even if it is just a click away.
In my math classes, starting at the Algebra II level, we use graphing calculators to graph functions. They are a remarkable tool, a mini-computer students hold in the palm of their hands. Graphing calculators can graph complex functions in an instant. I do use them in my calculus classes, but I use them sparingly. When I use them, I like to slow down and ask students the following:
What does this graph represent? Is this a good graph? What makes a good graph? How could it be made better? Why are we even bothering to make a graph of this function? What are the limitations of this graph? What are the assumptions? How much data do we need to make a good graph? If we have a certain number of data points, can we assume the rest of the data follows this pattern? What are the limitations of the electronic graphing calculators we use?
Do these limitations come into play in this problem?
If all goes well, we have a very good discussion.
We don’t need more technology in my classroom. I have a precious 50 minutes with them each day for 180 days. That is time when real, not virtual, relationships may grow. Each moment I am looking at my computer screen or Smart Board takes away from the time I am directly interacting with my students. Each time I walk down the hall and see a teacher at a computer, or each moment when I am at mine, I feel it is an opportunity lost. For me, more technology is not the answer. It only detracts from what I am truly trying to achieve as a teacher.
Jerry Brodkey teaches at Menlo-Atherton High School in Menlo Park, California. He has been a public secondary school teacher since 1975, and has taught most of the subjects in Social Studies and Mathematics. This year he is currently teaching ninth grade Algebra and Advanced Placement Calculus. He continues to find teaching to be challenging, enjoyable, and always intense. His undergraduate degree was from Rice University (BA 1974), and with graduate work at Stanford (MA 1976, Ph.D. 1987).
