Several years ago, a student working on a research project in my laboratory approached me with concern.“I’m doing something wrong,”she exclaimed. I had seen her research results and knew she was making good progress, so I was surprised to hear that she was having a problem. Over the next several days we went through her experiment; yet I could not find a problem. Finally, I asked her,“Why do you think you’re doing something wrong?” “Because I’m not getting what you said I should get,”she replied with some confusion.
Her response shocked me. I had not told her what she“should get”, but we had discussed some published hypotheses(假说) several weeks earlier. On seeing the research data that did not fit these predictions, I recognized that she had a new finding and came to change my hypotheses. But she was interpreting her results as a mistake. With almost four years of a college science major behind her, this student still had the common misunderstanding that science is a boring exercise in proving something we already know to be true.
But how can this happen? Throughout school, science is often described in textbooks as a series of“known”facts and figures; for example, DNA is a double helix; earthquakes occur at plate boundaries, etc. Unfortunately, the process by which these discoveries were made and how they fit into scientific progress are often ignored in the classroom. These details help show the nature of scientific discoveries and the tails help show the nature of scientific discoveries and the skepticism(质疑) that goes with new discoveries before they are accepted.
Understanding science is more than memorizing that DNA is a double helix. It is to have the ability to take in new information on diet, exercise, or disease and apply it to our own lives. Understanding the process of science and scientific problem-solving can help us make better decisions every day.
