This course is designed to familiarize you with the universe in which we live and with the principles of scientific inquiry that have enabled us to explore and understand that universe. The textbook is built around 5 themes:
The first part of the course will concentrate on the history and fundamentals of astronomy, including the night sky as seen from the Earth, the apparent motions of celestial objects, lunar and solar eclipses, phases of the moon, the historical development of astronomy, and the nature of light and matter and how they interact. The rest of the course will be about the formation and evolution of stars and galaxies. This includes a close look at the nearest star - our Sun - the different types and properties of stars, how they are born and how they die. We will also examine the huge collections of stars known as galaxies, including our own galaxy, the Milky Way.
Students will understand:
There are no prerequisites for this course. For more information about prerequisites, click here.
Lectures: The lectures will follow the chapters of the text as shown in the Course Calendar below; additional materials will also be presented in class. You are responsible for all the material covered in lecture, not just that presented in the text. You will find it of great benefit to have read the assigned chapters BEFORE they are discussed in class; this will enable you to ask questions in class if you do not understand something. You are encouraged to bring a hardcopy of the class presentations to lecture (see the Presentations section, below). You are expected to spend at least as much time studying as you do in class. For more information, see How to Improve Your Grade (also available on my homepage). Presentations: Each week, I will post a .pdf file here containing that week's presentation (powerpoint slides) for you to download. The like to the file is in the Course Calendar, below. These will not be identical to the slides shown in class; you should download the file and bring a hardcopy to class to write on during lecture. There will be fill-in-the-blank areas on the hardcopy, and spaces where you will be expected to fill in information. This is intended to help you learn the material, so you will do well on test days! Attendance: As you are responsible for any materials or announcements (including exam information, such as change in dates), attending class is to your benefit. Oral announcements made in class are binding and it is your responsibility to find out what has occurred in any class you might miss. Be on time. Arriving late or leaving early will not be tolerated. ABCD Voting Card: You will be expected to participate in class by "voting" for the correct answer in the multiple choice questions presented during lecture. To do this, print out the ABCD card. This is a PDF file; please print it in color and bring to class each day.
20% of your course grade will be based on homework assignments available on the online tutorial/homework MasteringAstronomy website at http://www.masteringastronomy.com. Each week's assignment is listed in the Course Calendar, below. You must read my Instructions for MasteringAstronomy for information on how to do the problems and submit them for credit. Information on improving your score is available there as well. To use the website:
Online help for the MasteringAstronomy website: Online help is available under the Help tab on the website, and FAQs are available at www.masteringhelp.com . It includes the information about how to register. You must also read my MasteringAstronomy instructions page. Due dates: All work for each week must be completed no later than 11:55 pm on Sunday. Assignments and due dates are in the Course Calendar, below. Late work: You will lose 5% each day an assignment is late. On MasteringAstronomy, this means that after 8 days, you will lose 40% so your homework grade will be below passing; and after 20 days, you will get zero credit.
5% of your grade will be based on the the Practice Quizzes at MasteringAstronomy. After you have completed the homework for the week, you need to complete the practice quiz assignment There are two parts: a Basic Skills/Definitions quiz and a Conceptual Quiz. They are multiple choice, and conducted in a tutorial fashion: you are prompted to try another answer if you get one wrong. There is a small deduction for each wrong answer. Hints are available; there is a bonus for each unopened hint however. To improve your score on the Practice Quizzes: Read my MasteringAstronomy instructions page. Late Quizzes: As with homework assignments, you will lose 5% each day after the due date; so after 20 days, you will get zero credit for the quiz.
There will be three non-cumulative, multiple-choice exams given in class. Each exam will be 50 multiple choice questions and will cover the material from the text and the lectures. Each chapter in the text has both a "Big Picture" list of bullet points and a "Summary of Key Concepts": these can help guide your review for the exams. The practice quiz assignments from the MasteringAstronomy website that you will do as part of your homework should be of great help in preparing for exams as well. In addition to the three in-class exams, there will also be an optional, cumulative final exam which may be used to replace one of the three in-class exams. If you take all three in-class exams and the final, I will drop the lowest of your four exam grades. This means that if you miss one of the three in-class exams, you MUST take the final. Each of the three exams that are used is worth 25% of your grade. There will be no make-up exams for any reason. IF YOU ARRIVE MORE THAN 30 MINUTES LATE FOR AN EXAM, OR AFTER ANYONE HAS FINISHED THE EXAM AND LEFT, YOU MAY NOT TAKE IT. Anyone caught cheating on an exam or talking after the exams have been handed out will fail the course and be referred to the authorities. The exams are closed book; no notes. If you have a conflict and cannot take an exam on the scheduled day, let me know ahead of time and we can arrange an alternative test date.
Your grade for the course is based on the average of your homework grades, practice quiz grades, and your exam grades as shown here:
Grades are available on the MasteringAstronomy website.
I understand that there is a Disability Resource Center available to me should I need it. It is my responsibility to contact them to process my request to have my needs met. I need to follow their procedures as to proper notification to the instructor.
