Taking Science Seriously
At the office, the voting booth, even the grocery store, we make decisions about science and technology every day. Take, for example, all of the decisions you must make about a simple carrot. Do you buy them conventionally grown or organic? What makes those carrots organic anyway, and why should they cost so much more? Is there any difference between fresh, frozen, and canned carrots, and if so, does it matter to you? Why are carrots good for your eyes? And what about the "paper or plastic" decision at the checkout? Are paper bags really better for the environment than plastic bags?
How you negotiate these questions is one indication of your scientific literacy. Though eggheads quibble about the definition, Stanford professor Paul Hurd coined the term, so we figure he earned a say here: "Scientific literacy is the competency required for rational thinking about science [and technology] in relation to personal, social, political, economic problems and issues that one is likely to meet throughout life."
Scientific literacy is the competency required for rational thinking about science [and technology] in relation to personal, social, political, economic problems and issues that one is likely to meet throughout life.
As we increasingly confront decisions about disease, energy, global warming, pollution, food and water (to name a few...), a central goal of science education is to develop scientifically literate citizens. National science education policies suggest that a scientifically literate public is required for democratic processes, personal decision-making, participation in civic and cultural affairs and economic productivity.
So, how are we doing?
Did you have to ask? Science and Engineering Indicators, a comprehensive national survey conducted since 1972, finds gaping holes in Americans' basic scientific knowledge. As Cornelia Dean put it in the New York Times, "fewer than a third can identify DNA as a key to heredity. Only about 10 percent know what radiation is. One adult American in five thinks the Sun revolves around the Earth, an idea science had abandoned by the 17th century."
Ouch. No wonder some people get away with describing evolution through natural selection as a "chance" process, when in fact, it's the ultimate example of design by trial and error.
- Only 26 percent of American adults felt they had a good understanding of science.
- Eight in 10 agree science is not receiving the attention it deserves in our schools.
- Forty-four percent grade science education at "C" or lower; only 12 percent give it an "A."
- Eighty-seven percent agree that, as a nation, we must begin to devote more funding toward science education.
- Ninety-four percent say teachers need more professional development and training.
Against this ominous backdrop, thousands of science educators descended on Boston last week for the 2008 National Science Teacher Association Conference. We dropped in to revel in
massive quantities of freebies the sight of teachers delighting in scientific unknowns, and their genuine determination to figure things out for themselves. (We must have stopped by the BirdSleuth booth a dozen times...)
After observing the enthusiasm and passion for learning among these teachers, we're convinced that the failure to create scientifically literate citizens cannot be blamed on science teachers alone. If Americans recognize that teachers need support and increased funding and attention, maybe, just maybe, we could solve the current crisis in science education (and education in general). You don't have to be an astronomer to be shocked that one person in five thinks the Sun revolves around the Earth.
The people are crying out for better science education. Educators are ready and willing.
So let's do it.
