STUDENT LEARNING OUTCOMES Appraise the benefits to society of astronomical research concerning stars and stellar systems. Evaluate the impact on Earth s characteristics of the evolution of stars and stellar systems. Evaluate astronomical news items or theories about stellar astronomy based upon the scientific method.

2 1 Astronomy lecture schedule, Spring 01 Morning Class Important: Dates of TESTS are fixed, but the lecture topics (shown in italics) are tentative. For example, we may or may not cover Observatories... on il nd, depending on how quickly we co ver the preceding material. Each test covers the material since the last test. See the WhatKnow list for details. Final Exam is comprehensive - it covers the whole quarter.

3 Astronomy reading assignments, Spring 01 Morning Class The reading assignments shown below should be done BEFORE each class. Some assignments apply to both the th and th editions of Stars and Galaxies by Seeds and Backman.

4 Astronomy GRADES step 1: step : step : You take various tests and the final I drop the lowest midterm score I calculate the final grade. Test 00 points each -00pts = 00 points of midterms Your final percentage = Test The points you earned, after dropping lowest scores as described at left 00 possible points FINAL EXAM 00 points There s no way I m gonna drop this one... I then round your final percentage to the nearest whole percent, and use the following grading scale: Notes: 1) A %-age like. rounds to an, so it s an A. -0 A - B - C 5- D <5 F If something causes you to miss a test, that will be the one that you drop. This means that there are NO MAKEUPS. You have to take all of your midterms and your final exam with YOUR SECTION of the class. I m afraid that my schedule won t allow me to give you a final at a different time in order to fit your vacation. You ll need to plan around the final.

5 Astronomy Rules and Procedures During the first few weeks of class, I will collect state-mandated attendance data using a sign-in sheet and/or seating chart. ADDING THE CLASS: If you add the class, make sure that your add code has worked, and that you have been properly added to the class. If not, it is your responsibility to check with the Admissions/Records office to find out how this can be corrected. After the end of Week, the College cannot process a late add, and you could find yourself not enrolled and not receiving a grade for the course, if you re not registered! DROPPING THE CLASS: I would like to see everyone complete the course, earn a good grade, and become excited about science. However, the realities of life sometimes get in the way. You should asess your situation realistically throughout the quarter. If you decide to drop the class, you must do so by the final date to drop with a w, or you risk receiving an F if you haven t earned enough points to pass the class. CLASS ENVIRONMENT: TESTS: Let me re-emphasize that: If you decide to drop the course, it is your responsibility to go to the registrar and drop yourself. The deadline is the end of the eighth week. VERY IMPORTANT INFORMATION ABOUT DROPPING AND THE END OF THE QUARTER: For many years, De Anza students have been given the impression that your instructor can drop you after the end of the th week. THIS IS CHANGING! We are no longer allowed to give a W on the final grade form. Additionally, I will NOT be able to drop you using a blue Addendum to Class List form after the end of the th week. If you have a personal hardship after the end of the th week, you will have to request a Late Drop using a white form called Petition for Exception to Registration Policies, which will be evaluated by the Registrar and/or the Academic Council. Remember that we have all chosen to be in this class. We should thus have an environment that fits this choice. Talking to your neighbor(s) while I m lecturing, reading non-course material in class, doing outside homework, and using wireless devices of any kind are not allowed in class, and may result in dismissal for the remainder of the class period. Such dismissal will count as an absence. After you start working on a test or quiz, you must hand it in before leaving the room. If you arrive late for a test or quiz, you won t be given extra time to finish it. On tests and quizzes, once the first person has turned it in and left the room, no further latecomers will be given tests. If you find yourself wanting to use a calculator on a test (such as to solve an extra-credit question that involves a numerical calculation), you ll need to use a regular calculator; you can t use a cell-phone calculator. NOTICE: Cheating on any exam or project is grounds for a failing grade in the class and a permanent note in a student's file. "Cheating" is defined (in this course) to be an effort by a student to obtain a grade by any means other than demonstration of that student's individual achievement in mastering the class material and/or fulfilling terms of a project. Further grounds for expulsion from the class include any activity which interferes with others' ability to benefit from the class (such as chronic distracting behavior) or which degrades the Planetarium's function or environment.
