Prerequisites: There are no prerequisites, but you should be excited about astronomy and want to learn a lot about it!  Although this is a "non-mathematical" course arithmetic and algebra skills are assumed.  See Background Topics page for a review of what I think that you should know by the end of the first week of class.  There are some sample quiz questions there also.  Common mistakes in this course include under estimating its difficulty, not reading the text, and not doing the homework.

Course Objectives: In general, the course objectives are for you to learn about and gain an appreciation for the motions in the heavens that are visible to the eye, the history of astronomy, the nature and potential of light and telescopes,  the nature of stars and their life cycle, the structure and evolution of the universe and the possibility of life on other worlds.  The official course objectives and Student Learning Outcomes (SLO) can be found at: Astronomy 25 Course Objectives.

Attendance: Attendance is MANDATORY to keep up (even the best students are very surprised  when they return after missing a class). We cover a lot of material every class.  I think that you will find the subject material amazing, and I will keep you very busy learning in class. 

Exams: A midterm and a final in-class exams will be given.  The exams will have true/false, fill-in-the-blank and essay questions. Some exams will include identifications and descriptions from slides. About 50% of the problems will be taken from the quizzes. THERE WILL BE NO MAKEUP EXAMS.

There will also be a written take-home exam that will be worth 50 points that will be assigned near the end of the semester. 

Quizzes: 5-7 quizzes will be given worth a total of 100 points. These will cover only the previous week's material. The total of the quiz scores will count as much as a test score.

Homework: Homework assignments will be given for every chapter. They will consist of questions from the text and will usually be worth 4 points per assignment. Due dates will be set for class days, and the assignment will be due at the beginning of class (turn it in on the front left corner of the desk when you arrive, do not wait for me to call for it).  No late homework sets will be allowed. If you are going to be late or not make it to class, then you will need to arrange to get the homework to me early.  There will be a total of 50 homework points.

Extra Credit:  100 points maximum for the semester for the regular class. All extra credit is due the last class meeting of the 13th week (except for the extra credit project).  See Extra Credit Instruction Sheet for further details.

Grading: Course grade is based on the exams, project, quizzes, and extra credit. I total all of your points at the end of the semester to determine your grade. The grade scale is as follows:

each exam    for the course

90 - 100 A     360 - 400 A

80 - 89 B       320 - 359 B

65 - 79 C       260 - 319 C

50 - 64 D       200 - 259 D

Students who withdraw after September 1st will receive a permanent grade record and after November 17th will receive a letter grade based on the entire semester's requirements.

Preparation: This is a tough class. I expect at least 4 hours of studying per week from you.  It is best if you can study about 50-60 minutes per day, five days per week.  That works better than trying to cram all of your astronomy studying into one or two longer days.  Some of the concepts that you will learn are difficult to grasp at first, and you will do better if you take it in smaller pieces five days per week. 

Disabilities:  If you have a documented disability and wish to discuss academic accommodations, please contact me as soon as possible..

Advice: The only stupid questions are the ones that you don't ask. Don't be concerned with what others think. If you don't understand something, ask questions. When you get lost in a lecture, raise your hand immediately. Asking questions is a sign of intelligence.

If I see that you are not asking questions, I will randomly select questions to ask YOU!

ASK QUESTIONS.
