“I’M A SCIENTIST, NOT A POLITICIAN!”: HOW TO INTEGRATE CRITICAL THINKING ABOUT VALUES INTO A GENERAL EDUCATION GEOLOGY COURSE (& WHY YOU SHOULD)
Fortunately, this initial resistance was overcome. Indeed, science provides rich material for discussing values in the classroom. Science is performed by human beings who make research decisions based in part on their own value preferences. Scientific discoveries have human consequences that every citizen must confront. The scientific process itself is grounded in the ethics of its participants. I would argue that a critical exploration of values within scientific disciplines should be considered part of a science courses core content, not an extra or gimmick.
In my historical geology course, we focused on several values-laden issues, including global climate change, evolution-creationism, Mars exploration, gradualism versus catastrophism, the commercialization of vertebrate fossils, and the cloning of extinct animals. At the end of the course, students indicated that the discussions and assignments about these real-world controversies greatly increased their interest in the geological topics we covered. Students left the class with a better sense of how scientists actually do their work, and of the non-scientific factors that affect scientific inquiry. They appreciated the way the course put a human face on science. Students also gained practice in how to critically evaluate and defend a position, distinguish between opinions and supported arguments, provide justifications for their own value choices, and make informed decisions based both on scientific information and consideration of the social consequences of their actions.
