NORMANDALE COMMUNITY COLLEGE PHYSICS 1114 ONLINE “Introductory Astronomy” Dr. Mark Hollabaugh, Instructor Office: S1307 Office Phone: 952-358-8461 Email: [email protected] SYLLABUS This syllabus is divided into two major sections: Course Adminstrative Policies and Procedures and Course Outline. The hyperlinks in the document should be active if you have a Web connection. You can easily print this document for offline use. Course Adminstrative Policies and Procedures Course Description: PHYS 1114 is an online introductory course in astronomy covering the tools and methods of astronomy, and the physics of the solar system, stars, galaxies, and the universe. Laboratory activities include data collection and analysis, and night sky observations. This course is especially recommended for future teachers or students intending to major in science or engineering fields. IMPORTANT NOTE: Two on-campus sessions are allowed for an online course. You will have an oncampus proctored mid-term exam and an on-campus proctored final exam. Details will be posted on NCC Online (i.e., D2L, https://normandale.ims.mnscu.edu/index.asp). Course Learning Outcomes: Upon successful completion of this course, the student should be able to 1. Identify significant persons responsible for the development of modern astronomy, 2. Explain the use of the basic tools of astronomical measurement and research, and the application of the laws of physics to those measurements, 3. Explain the importance of principal astronomical discoveries, 4. Identify, classify, and name the features of various astronomical objects (planetary, stellar, galactic, cosmological), 5. Describe the evolution of the universe and entities within the universe such as planets and stars, 6. Use astronomical terms intelligently, 7. Relate and apply textbook and classroom material to laboratory experiences, 8. Communicate his or her findings, analyses, and interpretations and discuss the accuracy of measurements and meaning of the results of laboratory work, 9. Perform simple calculations related to astronomy and interpret graphical representation of data, and 10. Master the specific unit learning outcomes. Prerequisite: MATH 0700 with a grade of “B” or better and READ 960. High school geometry recommended. ADA Statement: This course is available in alternate media by request. Required Materials: th Universe, 9 edition, Freedman, Geller and Kaufmann, W.H. Freeman & Co, ISBN 978-1-42923153 Calculator: You will need a basic, inexpensive scientific calculator such as the TI-30 series. A graphing calculator may be used but is not required. Only traditional calculators may be used on the mid-term and final exams. You may not use the calculator function of a cell phone, PDA or similar device. Computer: A Windows PC with high-speed Internet access and a sound card. Your computer will need the current free versions of QuickTime and Adobe Acrobat Reader. It also must be able to run JAVA applets. 2 Videos: There are several videos you will want to watch. All are available in the Normandale Library, or if you wish, many of them are available for online viewing for a small fee. Testing: The Mid-term Exam and the Final Exam are administered in a proctored environment at Normandale. Details will be posted on D2L. If you are not close enough to take the exams at Normandale at the times provided, you will need to make arrangements for taking the exams at another testing center at your own expense. Recommended: Depending on where you purchased your textbook, there may be a copy of Starry Night packaged with Universe. (Used books may not have the software intact and the college bookstore is not responsible for missing software in used books.) Starry Night is an excellent program and I encourage you to use it. It is available through the Normandale Bookstore, or directly from the publisher (http://www.starrynight.com/). Stellarium is a free open source planetarium program for your computer. It shows a realistic sky in 3D, just like what you see with the naked eye, binoculars or a telescope. To download it go to http://www.stellarium.org/. Mid-Term Exam and Final Exam: If you are unable to take the mid-term and final exams at Normandale, they MUST be taken in an approved testing center. Each student is responsible for locating a testing location that will administer and proctor the exams. Most MnSCU colleges and universities can accommodate a request for proctored testing. Many community colleges will offer this service. Students deployed with the military who wish to take the course may request proctoring by a superior officer. The purpose of this requirement is to insure the integrity of the testing procedure and that each student’s work is only his or her own effort. More information will be available on D2L. Important grading policy: Any request for a reconsideration of the grading of any graded assignment or exam must be made within two class days of the return of the item in question, the posting of a grade on D2L, or prior to taking the final exam, whichever comes first. Laboratory: There are twelve lab exercises. You will receive points for each lab by successfully completing a short online quiz based on the lab. Currently (2011) the labs are from the Online Labs for Introductory Level Astronomy from The Nebraska Astronomy Applet Project. Observations: You must make 10 observations of the night sky in conjunction with the labs and complete an observation report for each observation. Many of your observations can (and will) be “naked eye.” If you have access to binoculars, use them. Even small, low power binoculars will be helpful. Observing ideas specific to the semester in which you take the course will be posted on D2L. Please note that observing means actually looking with your eyes at something in the sky, not on a computer screen. Phases of the Moon: You must record the appearance and location of the Moon for one lunar month. You must complete this activity in order to get an A or B in the course. Policy on Missing Labs: Because this is a lab course, you cannot successfully complete the course without completing all the labs. If you have not completed three labs, your grade will be lowered one letter grade. If you are missing four, or more, labs, your final grade will be “F”. 3 Evaluation & Grading Breakdown: Specific grading requirements for labs, observations, discussion, etc., will be explained in D2L. Labs (12 5 points) 60 Observations (10 2 points) Syllabus & Unit Online Quizzes (15 5 points) Online Discussions (15 3 points) Phases of the Moon Observations Mid-term Exam Final Exam Total Points 20 75 45 20 50 80 350 Grading Scale: Average (%) Letter Grade 80-100 A 70-79 B 55-69 C 50-54 D <50 F Policy on Incompletes: Generally we assign an “I” grade when a student has extenuating circumstances that cause him or her to miss significant portions of a course. The “I” is an alternative to a “W” when the student has demonstrated a mastery of the material and only will miss a part of the course. An agreement between the instructor and the student is made as to the nature of the work to be made up and when it will be completed. I use the “I” very rarely and only upon extensive consultation with the student well in advance of the end of the semester. Extenuating circumstances include jury duty, military duty, and extraordinary family situations. A decision on a request for an “I” is handled on a case by case basis. Example 1: A student is in the National Guard and her unit is called to active duty for a brief deployment. In the tenth week of the semester she notifies me that she will miss the last quiz and final exam in the course. To date, all her work has been satisfactory. She agrees to take the last quiz and final exam upon her return. Her request is granted. Example 2: A student has not submitted any observations, missed submitting several labs and the mid-term exam. His performance in the course does not demonstrate an understanding of the material. The day before the final exam, he emails me requesting an “I” so he can better prepare for the final exam and not harm his GPA. His request is denied due to the untimely request and current standing in the course. From the Normandale Community College Catalog: “Normandale Community College believes that every person’s education is the product of his/her own intellectual efforts. Each student who enrolls and remains at Normandale, therefore, understands that to submit [individual] work which is not their own violates the purpose of the college and of his/her presence here. No intellectual community can maintain its integrity or be faithful to its members if violations of its central purpose are tolerated. In case such violations do occur, the instructor has the prerogative to take appropriate action.” Appropriate action may mean an “F” in the course and referral to the Dean of Students for further action. 4 COURSE OUTLINE Texbook readings refer to chapters and sections in Freedman, Geller and Kaufmann, Universe, 9th Ed.
