Some people who read this blog may have noticed another paucity of posts lately. I have the usual excuses – finishing up a paper and submitting it, being busy with research – and then unusual excuses – I went on a camping trip to Yellowstone National Park for a week, and I’m prepping to teach a class next month.
It’s the latter that is the reason for this post. I’m teaching my first class ever as Instructor of Record, meaning I have complete control over what’s taught and how. The class is a “summermester” meaning that it is every day for the entire month of June — June 1 through July 2, 11:00-12:35. The class is “General Astronomy: Solar System” for non-majors without a lab component. Checking the roster shows that, at the moment, there are about 25 students signed up, 1 freshman, 3 sophomores, about 15 juniors, and the rest seniors. Most are liberal arts students, but there are some from the sciences.
One of the assignments that I have already written is a course-long writing assignment. It requires the students to look into one of four modern popular astronomy-related pseudosciences — Planet X and 2012, The Apollo Moon Hoax, Is the Universe <6000 Years Old?, and The Hollo Earth "Theory."
Application of Critical Thinking
I will be passing out this assignment the first day of class. I will also be requiring intermediate progress items: (1) At the end of the first week (only 4 days into the class) they need to turn in an outline of their paper that lists the topic, sub-topics they’ll discuss, and at least 3 references they’ll use; (2) at the end of the 3rd week, a rough draft to me; and (3) at the end of the 4th week, a close to final draft that they’ll exchange with someone who’s NOT doing their topic, read over the weekend, and then peer-review on Monday.
As you can see, there is a reasonable emphasis on this paper. I also hope to gear the class towards an Astronomy Cast -inspired “How do we know what we know?” approach, and I plan to bring in pseudoscience topics that are related to homeworks and tests (I’m a fan of Phil Plait’s question of, “How can I state with great confidence that over 95% of violent crimes occur within 1 week of the full or new moon?”).
How to Teach?
The point of this post is to solicit advice from readers: How can I actually write an introductory lecture on this subject? I want the lecture to be no more than 20 minutes, and I would like it to teach science from pseudoscience without (a) getting preachy and (b) WITHOUT examples at the beginning. The last half of the lecture can be examples (good class discussion starters!), but I would really like to introduce the topic without falling into debunking.
I do have a wonderful 2-minute clip from a Coast to Coast AM caller who rambled about Earth’s gravity field collapsing pushing the moon away removing our atmosphere which flash-froze animals that I plan on playing towards the end.
My thoughts so far are showing the scientific method flow chart, or maybe asking the class how they would go about showing something is “true,” contrast that with methods employed by pseudoscience proponents … but those ideas are fairly vague. I start in a week; if people have advice, I’m interested in hearing (reading) it!
