An important report from Stanford

Posted on by

Science Education in an Age of Misinformation is an important new report from Stanford University. We welcome this report, especially because the authors reached the same conclusion that we have, namely that national and state science education standards need to be revised in order to teach students to distinguish between real science and junk science. As the Stanford report notes, the cultural context is significantly different now than it was when the NGSS was developed and published, with misinformation playing a far greater and more harmful role than it once did.

Discussions leading to the report were led by Jonathan Osborne, an emeritus Professor of Science Education at Stanford, who was also the lead author. More than a dozen people contributed to the discussions and writing of the report, including Bruce Alberts, who currently holds the Chancellor’s Leadership Chair in Biochemistry and Biophysics for Science and Education at the University of California, San Francisco. Professor Alberts is a former President of the National Academy of Sciences and a former Editor-in-Chief of Science magazine. It seems significant to us that Alberts, a pillar of the science community, recognizes that current science education standards need attention.

To the best of our knowledge, the work of the Stanford group and our own work were entirely independent. Certainly, we were unaware of their existence until last month. Nonetheless, there are a great many similarities in our concerns and recommendations. Among the overlaps are these: recognizing that educating students about misinformation and judging the quality of sources is vital; helping students develop a better understanding of how scientists reach consensus; developing “competent outsiders” who can make use of science; the need for greater digital literacy; reducing emphasis on teaching science that few students will ever use; and changing other elements of the education system associated with standards, such as high-stakes assessments.

We are encouraged by publication of this report and hope that it stimulates further discussion and, eventually, action to revise and improve science education standards. Our previous post offered specific suggestions for how and why the NGSS should be improved.

“A Response to the National Academies’ 2021 Call to Action”

A few days ago Science Educator, a journal produced by the National Science Education Leadership Association (NSELA), published an article by me and Penny Noyce responding to the Call for Action for Science Education published last summer by the National Academies of Sciences, Engineering, and Medicine. The topic of the article is teaching science for citizenship, and the abstract reads as follows:

The 2021 publication of Call to Action: Building Opportunity for the Future by the National Academies of Sciences, Engineering and Medicine offers an opportunity to consider re-balancing K-12 science education in the United States. Besides a strong and detailed appeal to provide a more equitable education, the document calls for science education to focus more purposefully on developing an “informed citizenry that makes fact-based decisions in everyday life.” An approach to science education that reaches beyond scientific theories, facts and methods to consider how science interacts with everyday and civic life, including personal, economic, and ethical concerns, has been called a Vision II approach. Benefits of such an approach are likely to include greater student engagement, practice in constructive group discourse, exercise of critical thinking skills, and strengthening of civic skills needed in a democracy. We suggest pertinent resources and outline the relatively modest changes in policy, curriculum and instruction required at the national, state, district and classroom level to create a more effective approach to teaching science for citizenship.

The Science Educator article cites more than a dozen studies documenting the benefits of teaching science in this broader context. For example, to “inoculate” students against scientific misinformation, which has become so ubiquitous, teachers need to teach media literacy skills that are not “science,” per se. Also, almost everyone realizes that greater knowledge of the intersection of civics and science is essential to preserve American democracy; even Science magazine published an editorial last year recommending “a new spirit of cooperation between the science and civics education communities.” 

This article includes an analysis of the Next Generation Science Standards, noting that,

The most significant component of the NGSS is its list of more than 200 Performance Expectations describing what students should know and be able to do at various grade levels. Those are the minimum expectations for students and the highest priorities for teachers. … They also set the boundaries of high-stakes testing.

Among these 200-plus Performance Expectations only a handful even hint at a broader view of scientific literacy, one that includes not only scientific findings, theories, and methods, but also personal, economic, and ethical concerns. In everyday life, decisions involving science are often made by non-scientists, who must consider a variety of perspectives beyond science. As the National Association of Biology Teachers has written in a Position Statement, excellent biology teachers “follow an integrated approach by incorporating other subjects, technology, society, and ethics.” All science teachers need to follow this advice if schools are going to develop “an informed citizenry that makes fact-based decisions in everyday life.” Teachers need to help students learn to learn about science even after they leave school and have no textbook to guide them.

There are innumerable science-related questions non-scientists need to answer, including politicians, city and town officials, and ordinary citizens. Who decides that COVID vaccines are safe, and how do I know they really are? Do vaccines cause autism? Will this advertised product really drain toxins from my body? Whose job was it to protect the public water supply in Flint, Michigan, and could that happen in my town? What are the pros and cons of buying a hybrid versus an electric car; how can I evaluate the advertisers’ claims; what am I willing to pay? Should I let my child play tackle football? Should I go to a tanning parlor before my beach vacation? How much should states and cities pay for clean energy and why, and should I support a particular ballot question about this?

The most important recommendation made in our article is that state and local policymakers explicitly set a high priority on teaching science in the context of societal and personal issues. Radical changes are not necessary. What is needed is a modest, feasible shift in priorities encouraged from the top down. Like adding yeast to bread dough, just a little bit can make a big difference in the result.

The full article is a NSELA members-only benefit. Check with your library or other science educators who may have access. You can also send an email to either Andy Zucker or Penny Noyce requesting a copy of the Science Educator article.

Developing Students’ Scientific Literacy

Posted on by

The primary goal of K-12 science education should be to develop students’ scientific literacy. For example, the New York State P-12 Science Learning Standards identifies that very goal, stating that, “our education system [should] keep pace with what it means to be scientifically literate.”

But what exactly does “scientific literacy” mean? One way to define it would be to stack up the Next Generation Science Standards (NGSS), the appendices to the NGSS, and the Framework for K-12 Science Education (the template for the NGSS). Scientific literacy could be defined as everything in those documents. But that is close to 1,000 pages of text.

English teachers and science teachers can agree that 1,000 pages makes for an unwieldy definition. Can we do better?

The Program for International Student Assessment (PISA)—which periodically tests thousands of students in dozens of countries across disciplines, including science—developed a more concise definition. For PISA:

Scientific literacy is defined as the ability to engage with science-related issues, and with the ideas of science, as a reflective citizen….

That’s not bad. Actually, it’s quite good. PISA’s definition can easily encompass the three dimensions of the NGSS: disciplinary core ideas (DCIs), scientific practices, and cross-cutting concepts. Scientifically literate people know some science content and understand, generally, how scientists practice science and develop new knowledge.

But beyond that, and equally important, PISA’s definition emphasizes, as the NGSS does not, that scientific literacy is for everyone, not just for college graduates or those who often use science as part of their jobs. In other words, the goal of developing students’ scientific literacy is simply not the same as “preparing students for college and careers,” the stated goal of the NGSS. The latter is a cramped, narrow view of scientific literacy. It conveys a message that the NGSS is a “prerequisite” to the real work that comes later: college and careers. “Don’t worry about applying science outside of college or careers,” is an unintended message, especially to the millions of students who are not college-bound.

For more than three decades, from the time that Science for All Americans was published by the American Association for the Advancement of Science in 1989, key leaders in science education have focused on educating all students. As the AAAS book states, “When demographic realities, national needs, and democratic values are taken into account, it becomes clear that the nation can no longer ignore the science education of any students,” including the non-college-bound student and the many others who won’t use much science in their careers. The book’s introduction expands on the idea:

Education has no higher purpose than preparing people to lead personally fulfilling and responsible lives. For its part, science education—meaning education in science, mathematics, and technology—should help students to develop the understandings and habits of mind they need to become compassionate human beings able to think for themselves and to face life head on. It should equip them also to participate thoughtfully with fellow citizens in building and protecting a society that is open, decent, and vital. America’s future—its ability to create a truly just society, to sustain its economic vitality, and to remain secure in a world torn by hostilities—depends more than ever on the character and quality of the education that the nation provides for all of its children.

As Penny Noyce and I have written recently in Education Week, the narrow view of the NGSS almost certainly makes science class less appealing to many students. People are interested in themselves and other people, and the national science education standards say little that humanizes science, little that could literally put a human face on the subject. For example, the NGSS does not mention a single scientist by name and the words “women” and “minorities” don’t appear in the text of the NGSS.

If Americans want to develop all students’ scientific literacy, Penny and I believe science teachers need to put a greater emphasis on the following five topics, “keys to scientific literacy.” These are:

  1. Teach science in the context of societal and personal issues
  2. Tie scientific literacy to traditional forms of literacy
  3. Teach how to find reliable scientific information and how to reject junk science
  4. Include some important events in the history of science
  5. Help females and minority students realize their potential in science

The NGSS devotes hundreds of pages to identifying what students should learn, focusing almost entirely on science content and scientific practices. By having students learn mainly about investigating scientific “phenomena,” the NGSS leaves behind many other important aspects of scientific literacy.

The NGSS is one piece of a bigger system

Several reviewers noted that education standards like the NGSS are only one influence on classroom instruction, whether in science or other subjects. We heartily agree! Their comments are an important reminder.

The quality of science teachers, the support they receive, the amount of time allocated to teaching science, the nature of high-stakes tests, support of STEM education by parents and the community—these are just a sample of other important influences on teaching and learning science. One reviewer wrote, “I agree with the ultimate goals for raising scientifically literate students … but I question what new and improved standards will do without addressing the current lack of infrastructure to implement them.”

The white paper does not claim that improving the NGSS is the one and only way to improve science education. At the same time, the NGSS promotes an excessively narrow vision of science and scientific literacy, so we should not be surprised when many teachers adopt that narrow vision.

As an example, too many parents believe that vaccines cause autism. Students graduating high school ought to know that the Centers for Disease Control and Prevention (the CDC) is an excellent source of information about vaccine safety and about many other public health issues. Similarly, students should learn that the Intergovernmental Panel on Climate Change (the IPCC) is a primary source of information about the causes and the impacts of climate change. Organizations like the CDC and the IPCC are central to NGSS practice #8, “obtaining, evaluating, and communicating” science-related information, bringing together experts from many institutions to synthesize and vet scientific findings. Such institutions are one key mechanism for determining scientific consensus, if and when it exists. Yet the NGSS makes no mention of any scientific institution. Nor does it explain how science helps to inform public policy—about vaccines, climate, food safety, or other issues. This is short-sighted.

Improving the NGSS is no guarantee that science instruction will improve, yet guidance from national standards cannot be ignored merely because other factors are important, too.

Thank you for reading this blog. We will add posts several times each month, or even weekly. You can subscribe by clicking the link at the top of the right column.

Your participation in the conversation about science education standards can be important. Education standards are intended to meet the needs of a large number of individuals and groups. By the same token, changing standards requires widespread discussion before revisions are made.

We worked on the white paper “Opportunities to Improve the Next Generation Science Standards (the NGSS)” for more than six months before posting it on this website in late 2019, making the paper widely available. Earlier, several experts agreed to review a draft and provide comments, for which we are grateful. In future blog posts we will highlight some of the comments and suggestions we received from them and from others, and we invite you to offer your own comments on this blog.
