Course Description:
The course description, credit hours, and enrollment restrictions can be found at this link.

Purpose and Learning Goals:
Students will be exposed to a broad brush of topics in astronomy with a focus on what has been learned from cutting-edge research in the past decade. Students will become familiar with the night sky, astronomical instruments/measurements, our solar system, the evolution of stars and galaxies, and the history/future of the Universe itself.

The text for this class is "Astronomy: A Beginner's Guide to the Universe (7th Ed.)" by Chaisson & McMillan. We will be using the version that comes with the Modified Mastering Astronomy software. The ISBN number for the "binder ready" hardcopy is ISBN-13: 978-0-321-96294-2. This is what is at the book store ($124). You can also purchase the binder-ready book (and Mastering Astronomy access code) directly from the publisher here for $107.67. Note that this is the short version of Astronomy Today (which you don't want) by the same authors. You should NOT buy it from Amazon as that will come with an out-of-date electronic access code.

If you would prefer a bound copy of the text (and Mastering access code) you can do so here for $172.27. If you just want the eText (the other options come with it automatically) or already have the book (but need a new Mastering code), then go here, then "Register/Student", put in "richards05395" for the Course ID and sign in with an existing user ID or create a new one, then choose either the eText+Mastering option (was $91.30) or just the Mastering option (was $60.50; if you already have the book).

To access Mastering, please see this link (do NOT do a Google search--it will take you to an old version). Again the Course ID is "richards05395". You will need access to this weekly. If you are not sure if you will stay in the course, you have an option to get a 2-week trial access to Mastering, which you will need to convert to full access if you remain in the course.

For anyone looking for more, I recommend Prather et al.'s Lecture Tutorials for Introductory Astronomy (3rd Ed.). It isn't strictly required, but it would be helpful to have. You might also be interested in Bad Astronomy by Phil Plait, but it is also not required reading for the course. Those of you that are particularly interested in learning about the night sky and constellations should buy a copy of a recent Sky & Telescope or Astronomy magazine.

Students are strongly encouraged to at least skim through the readings for each lecture before class in addition to reading the material in detail after the lecture.

We will meet for lecture twice a week for 1 1/2 hours. Lectures will consist primarily of information based on the readings. In-class activities (1-2 per lecture) during the lecture will be part of your participation grade (and will count 5% of your final grade). You will be allowed to miss 1 lecture in the first half of the quarter and 1 in the second half without any penalty.

Office Hours:
Tentatively set for WF 3:30-4:30pm. I may have to adjust these after the first week of classes. For those that cannot make those days/times, I can arrange for some online office hours in the evening if there is enough demand.

Homework & Quizzes:
Homework will be given each week on the Mastering Astronomy site (course ID: "richards05395"). The Homework should be done completely on your own as it is meant to prepare you for the Quizzes (and Final Exam). Weekly Quizzes on the previous week's material (reading, lectures, and homework) will similarly be completed online (also completely on your own) prior to the start of class on Tuesdays. To ensure that everyone is doing their own work, we will repeat the quizzes (with similar, but not identical questions) in class on random Tuesdays. Quizzes will be mostly multiple choice, labeling, matching, true/false, etc. There will be ~10 quizzes during the quarter. I will drop your lowest quiz grade; no make-up quizzes will be given, so don't be late for class on Tuesdays in case there is a pop quiz. Homework will be available online from Thursday afternoon until Sunday night; Quizzes from Sunday morning until class on Tuesday.

Currently no midterm is planned. A (comprehensive) final exam will be given during a time/date to be decided during the exam week. It will be mostly multiple choice, T/F, etc. questions with a few short answer and drawing problems. For the multiple choice and T/F part, your score will be the average of your own score and that of your group. I'll explain more about this in class.

10 point scale (90=A-, 80=B-, 70=C-, etc.) using the following weighting:

Students are responsible to monitoring their progress using the online gradebook. The table is sorted by the last 4 digits of each student's Drexel ID number. It is your responsibility to let me know (in a timely fashion) if I am missing any grades for you. I will NOT be using the gradebook in Mastering or Learn. This enhanced gradebook is provided in return for submission of course evaluations at the end of term.


Drexel's policies on Academic Integrity and Course Dropping apply to this course.

The nature of this course means that changes to its parameters may need to be made during the quarter. In the case of such events, students will be notified by the instructor through their official Drexel e-mail.

Student with disabilities requesting accommodations and services at Drexel University need to present a current accommodation verification letter (AVL) to faculty before accommodations can be made. AVL's are issued by the Office of Disability Services (ODS). For additional information, contact ODS at, 3201 Arch St., Street, Suite 210, Philadelphia, PA 19104, 215.895.1401 (V), or 215.895.2299 (TTY).

If you have read this far, please send the instructor an e-mail (prior to the first lecture) for one unit of extra credit. Please indicate that you are aware that you need both the book (7th Ed.) and acccess to Mastering Astronomy, that you should only follow the links above to get to Mastering Astronomy (then bookmark it), that the gradebook is at the link above and not in Mastring Astronomy or in Drexel Learn, and that I don't allow make-up quizzes or exams (and that it will be a fun and interesting course!).
