Why We Must Teach Evolution in the Science Classroom
By Lorentzen, Laura
I don't remember when I first learned about the theory of evolution, but nowadays I find myself reading of it a great deal in the popular press and hearing it discussed in the media. As my daughter enters elementary school, I find myself anxious to discuss with her teachers what they will cover in science class and where in their curriculum they plan to teach evolution. OUR COUNTRY HAS LAWS THAT SEPARATE church and state. Public institutions like schools must be neutral on the subject of religion, as required by the Constitution's First Amendment. Our courts have mandated that creationism is not an appropriate addition to the science curriculum in public schools; yet supporters of intelligent design press to have antievolutionary discussions enter the science classroom. Creationists even advocate that, when leaching evolution, educators should add the disclaimer that it is "just a theory."
On the opposite side of the argument, "intelligent design fails on hold basic tenets of a scientific theory; design cannot be observed, and it cannot be tested," writes Mary Crowley in the New York Academy of Sciences Update magazine.2
The National Science Teachers Association (NTSA) argues the importance of teaching evolution in one of its own, most fundamental, writings - its position statement: "If evolution is not taught, students will not achieve the level of scientific literacy they need." The NSTA recognizes that evolution is a major unifying concept across multiple disciplines of science, and the National Science Education Standards, updated in 1996, recommend evolution as a means to "unify science disciplines and provide students with powerful ideas to help them understand the natural world,"1 Indeed, the evolutionary perspective is vitally important in modern molecular and cellular hiology, not to mention biomedicine - for example, the nature of disease and targeted treatments - and other scientific disciplines.
As we discuss fundamentals of science education for students, let's also discuss how we prepare our teachers for their role in the science classroom and broader educational system. Are we sufficiently preparing them to teach evolution? Are we equipping them with the knowledge and resources to withstand an onslaught of antievolutionary pressure from the public? Some support, such as various published materials available from the National Academy of Sciences, exists. However, much more is needed in terms of information and public education. For example, Nehm and Schonfeld's 2007 study of more than 40 pre-certified secondary biology teachers in New York City showed that, even after a semester-long graduate evolution course, the majority of science teachers "still preferred that antievolutionary ideas be taught in school."4 As our "science teachers are an important 'missing link' between scientists' understanding of evolution and the general public's ignorance of, or resistance to, the idea,"5 we must do more.
The curriculum taught in our science classrooms should be that which is based on measurable, quantifiable fact. Nonscientific content has its place as well, such as philosophy or religion classes. Let's just be certain that evolutionary theory is a standard feature of our science classroom lesson plans so that we ensure our students' literacy, competitiveness, and futures in the global world of scientific study.
