Unformatted text preview: Welcome to Biology 180! Today’s questions: I. What is this course about? II. How does this course work? III. How does science work? I. What is this course about? Questions: 1. My father finished medical school in 1946. Penicillin wasn’t widely available in the U.S. until 1948. What did he learn in school? 2. I was a graduate student from 1985‐1990. I’m the co‐author of an Evolutionary Biology text where ~90% of the citations are more recent than that. What did I learn in school? 3. When I learned CPR, we were taught to do 15 chest compressions and then 4 breaths. If you didn’t do this correctly, you failed the certification test. Recent data suggest that CPR consisting only of chest compressions is dramatically more effective in saving lives than the system I learned. What do you conclude from these observations? Bloom’s taxonomy of learning Analyze: Can I recognize underlying patterns and structure? Evaluate: Can I make judgments on the relative value of ideas and information? Synthesize: Can I put ideas and information together to create something new? Apply: Can I use these ideas in a new situation? Understand: Can I explain these ideas to someone else? Remember: Can I recall key terms and ideas? II. How does this course work? • Reading quizzes • Clickers • Practice exams • Exams • Labs The image cannot be display ed. Your computer may not hav e enough memory to open the image, or the image may hav e been corrupted. Restart y our computer, and then open the file again. If the red x still appears, y ou may hav e to delete the image and then insert it again. Grading: What best describes the 180 system? 1. Curved via pre‐set median (usually ~2.7) 2. Curved by pre‐set percentages (5% As, 15% Bs, etc) 3. Standardized (90‐100% of total points A, 80‐90% B, etc) 4. Competitive 5. Non‐competitive III. How Does Science Work? Start by exploring what is not science … e.g. pseudoscience Occult/UFOs Shamanism/quackery/witchcraft Amulets, lucky charms, superstition Astrology/horoscopes/Tarot/palm reading Exercise: Are horoscopes accurate? 1. Read the 12 horoscopes on the sheets being handed out (please share the sheets; groups of ~4) NOTE: • These are for March 2010 and are from the most‐ visited astrology website • They are in random order 2. Decide which horoscope is yours (which best fits your life experience this month). Write this down— next to the horoscope. Other pseudoscience hypotheses: 1. Touching crystals can protect you against bad energy. 2. Certain types of behavior bring good luck. 3. Disease is caused by people wishing ill on others. Predictions: 1. If you enter X’s house and don’t touch crystals in a prescribed order, bad things will happen. 2. If you don’t change underwear during March madness, your favorite team is more likely to win. 3. If someone has cast a spell on you, a specific ceremony can counter the spell and maintain your health. How could you test each prediction? ...
