As this is an entirely new course, and will be consuming a lot of my mental energy, I plan to post occasional reports on what I&#8217;m doing to the blog.<\/p>\n<p>Today was the first day of class, so a good chunk of the time was spent on introducing the basics of the course (my <a href=\"http:\/\/scienceblogs.com\/principles\/wp-content\/blogs.dir\/467\/files\/2012\/04\/i-6c39c33fa66114d5f7e8645d2d76a653-010412Notes.pdf\">PowerPoint slides<\/a>, for those who care), and going through one slightly silly example.<\/p>\n<p>The stated <a href=\"http:\/\/www.union.edu\/Resources\/Academic\/advising\/gen_ed\/srs.php\">learning goals for SRS courses<\/a> (students should learn how to formulate a research question, find and evaluate evidence, present results, etc.) mean that they&#8217;re really basically &#8220;How to make an academic argument&#8221; courses, so I&#8217;m taking that as a general theme. It&#8217;s hard to assign reading for the first day of a course, though, so I went with an illustrative example that didn&#8217;t require pre-class reading: <a href=\"http:\/\/scienceblogs.com\/principles\/2010\/10\/the_astrophysics_of_bedtime_st.php\">the physics of <cite>Goodnight Moon<\/cite><\/a>. It&#8217;s admittedly silly, but serves as an illustration of the basic process: you read it a zillion times, and you start asking &#8220;How long does this take?&#8221; After puzzling over it for a while, you realize you can use size of the Moon as a reference for its own motion, and then a little Googling gets you the size. Put that together with a little reasoning from common knowledge, and you can get an answer to the question.<\/p>\n<p><!--more--><\/p>\n<p>I think it went over reasonably well; they were kind of quiet, but it&#8217;s the first day. It took quite a while to get them to see that the Moon can serve as its own scale reference, but they got the angular speed (360 degrees in 24 hours) pretty quickly.<\/p>\n<p>I also gave them their first major assignment, which is to make a measurement of the performance of some timekeeping device. I gave them three timing resources: a digital timer like the <a href=\"http:\/\/scienceblogs.com\/principles\/2011\/05\/the_testing_of_time_measuring.php\">one I tested last year<\/a>, one of the <a href=\"http:\/\/scienceblogs.com\/principles\/2012\/01\/the_testing_of_time_the_surpri.php\">plastic sand timers I tested last week<\/a>, and the link to <a href=\"http:\/\/time.gov\/widget\/\">NIST&#8217;s official US time widget<\/a>. I left the exact thing to be measured up to them (the due date&#8217;s the 25th, so they have time), and that gives them a reasonable number of options. We&#8217;ll see how that goes.<\/p>\n<p>Friday&#8217;s class is the first of a few that will deal with kookery of various sorts, with <a href=\"http:\/\/www.haydenplanetarium.org\/tyson\/read\/2003\/03\/01\/stick-in-the-mud-astronomy\">Stick-in-the-Mud Astronomy<\/a> assigned as reading, and a clip from <a href=\"http:\/\/www.youtube.com\/watch?v=Mpggvt-Lz4M&#038;feature=related\">this <cite>Ancient Aliens<\/cite> episode<\/a> planned as a starting point for in-class discussion (the bits about <a href=\"http:\/\/www.newgrange.com\/\">Newgrange<\/a>, which is also in the reading assigned from <a href=\"http:\/\/www.amazon.com\/gp\/product\/0312603517\/\">Dan Falk&#8217;s <cite>In Search of Time<\/cite><\/a>). These introduce the idea of solstices and equinoxes, and also provides an easy example of a slick but deeply, deeply flawed argument that we can easily take apart. Sadly, it does not feature my favorite of the kooky Ancient Alien theorists, but you can&#8217;t have everything.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>As mentioned a few times previously, the class I&#8217;m teaching this term is a &#8220;Scholars Research Seminar&#8221; on time and timekeeping.
