The Covid-19 crisis has put a spotlight on the importance of science. More than at any time I can recall (with the possible exception of panic over the Soviet launch of Sputnik), scientists are in the news. We count on them to find a cure for people with the Covid-19 virus and a vaccine to prevent new cases. We count on them to predict the progression of the pandemic, and to discover public health strategies to minimize its spread. We are justifiably proud of the brilliance, dedication, and hard work scientists are exhibiting every day.
Yet the Covid-19 pandemic is also throwing a harsh light on the scientific understanding of the whole population. Today, scientific literacy can be a matter of life or death. Although political leaders, advised by science experts, may recommend what we should do to minimize risks to ourselves and our families, people have to make their own judgments about what is safe and what is not. The graphs in the newspaper showing how new infections and deaths are trending have real meaning. They should inform what choices people make. We are bombarded with advice on the Internet, from friends and neighbors, from television, in the news. Yet these sources are likely to conflict. Which should we believe? Is it safe to go for a walk? To the grocery store? To church? To a party? Is Grandpa safer at home or in assisted living?
Scientific literacy is something we all should have learned in school. I would define scientific literacy as an understanding of scientific method, a basic understanding of how things work in nature and in technology, and an understanding of how scientists generate new knowledge and subject possible treatments, such as medicines, to rigorous tests. All of these understandings, and many more, are ordinarily useful in generally understanding the news, for example, but for most people they do not have major personal consequences. But now they do, and it is terrifying to hear the misconceptions and misinformation people have. In the current situation, a misconception or misinformation can kill you, or cause you to make decisions that can lead to the death of a family member.
The importance of scientific literacy in the whole population is now apparent in everyday life. Yet scientific literacy has not been emphasized in our schools. Especially in elementary schools, science has taken a back seat, because reading and mathematics are tested every year on state tests, beginning in third grade, but science is not tested in most years. Many elementary teachers will admit that their own preparation in science was insufficient. In secondary schools, science classes seem to have been developed to produce scientists, which is of course necessary, but not to produce a population that values and understands scientific information. And now we are paying the price for this limited focus.
One indicator of our limited focus on science education is the substantial imbalance between the amount of rigorous research in science compared to the amount in mathematics and reading. I have written reviews of research in each of these areas (see www.bestevidence.org), and it is striking how many fewer experimental studies there are in elementary and secondary science. Take a look at the What Works Clearinghouse, for another example. There are many programs in the WWC that focus on reading and mathematics, but science? Not so many. Given the obvious importance of science and technology to our economy, you would imagine that investments in research in science education would be a top priority, but judging from the numbers of studies of science programs for elementary and secondary schools, that is certainly not taking place.
The Covid-19 pandemic is giving us a hard lesson in the importance of science for all Americans, not just those preparing to become scientists. I hope we are learning this lesson, and when the crisis is over, I hope our government and private foundations will greatly increase their investments in research, development, evaluation, and dissemination of proven science approaches for all students.
