Syllabus statement regarding absence due to illness

Students who are absent due to illness may use the online recordings and lecture notes provided on my course website to complete assignments and will be granted an extension to submit their work. 

If a student has the flu or COVID, they should not attend any classes until they are no longer contagious. I will provide reasonable accommodations for students who become ill or indicate a need to isolate themselves. If a student is absent from class for an extended period, a withdrawal (W) before the deadline should be strongly considered.

Syllabus statement regarding the use of generative AI programs 

You are welcome to use generative AI programs (for example ChatGPT) in this course. These programs can be powerful tools for learning and other productive pursuits, including completing some assignments in less time, helping you generate new ideas, or serving as a personalized learning tool. However, your ethical responsibilities as a student remain the same. You must follow CofC’s Student Code of Conduct. If you use a generative AI tool to develop content for an assignment, you are required to cite the tool’s contribution to your work. In practice, cutting and pasting content from any source without citation is plagiarism. Likewise, paraphrasing content from a generative AI without citation is plagiarism. Similarly, using any generative AI tool without appropriate acknowledgment will be treated as plagiarism. You may not use AI tools during midterm tests and the Final Exam.

Here are some specific expectations for your use of AI generation tools in this course: 

· You can include AI generated content verbatim into a writing assignment with quotations and a citation. 

· You can paraphrase AI generated content with a citation. 

· You can include non-text AI generated content (images, video, code, etc.) with an appropriate citation, when expressly permitted in the assignment prompt. 

· You will conduct your own research and generate bibliographies yourself for topics that you have researched. 

· You will not use or present generative AI content that you pass off as your own work. 

· You may use AI-generated content with a citation to create your AstroNews presentation.

Finally, it is important that you recognize that generative AI tools frequently provide users with incorrect information, create professional-looking citations that are not real, generate contradictory statements, incorporate copyrighted material without appropriate attribution, and sometimes integrate biased or offensive concepts. Code generation models may produce inaccurate outputs. Image generation models may create misleading or offensive content.  While you may use these tools in the work you create for this class, it is important to note that you understand you are ultimately responsible for the content that you submit. Work that is inaccurate, biased, unethical, offensive, plagiarized, or incorrect will be treated as such during the evaluation of your work. 

Course Objectives:

One of the goals of this class is to reveal to you some of the wonders of our cosmos. Astronomy 130 will begin with an introduction to the nature of light and a description of the optics and telescopes used by scientists to collect electromagnetic radiation from objects in the Universe. The course will cover the birth, evolution and death of stars and the nature of galaxies including our own Galaxy the Milky Way. You will learn about exotic objects in our Universe such as neutron stars, black holes, quasars and active galactic nuclei. The course concludes with a description of the evolution of the Universe and a presentation summarizing ongoing searches for extraterrestrial life in our Universe.

I recommend that you review the material before it is presented in class. This will help you to better understand the concepts and enjoy the class. I expect your active participation in the class.

General Education Natural Science Learning Outcomes:

1. Students apply physical/natural principles to analyze and solve problems (This outcome will be assessed by writing a report of one of the labs. It will count as 7.5% of your final lab grade.)

2. Students explain how science impacts society (This outcome will be assessed in the lab class using an assignment involving writing a letter to a public official about an astronomy-related current event. It will count as 2.5% of your final lab grade.)

Outcome 1 will be assessed in a lab report and outcome 2 will be assessed in the lab via a signature assignment.

Course-specific Learning Outcomes

1. Students distinguish the nature and significance of the following: instruments used in astronomy, stars (binary, variable), star clusters, interstellar matter, galaxies and cosmology.

2. Students demonstrate how the measurement of light is used to interpret physical characteristics of the universe.

3. Students recognize the origins of astronomical objects.

4. Students apply physical laws to reveal the nature of astrophysical phenomena.

Astro-News:

Each class will contain a segment called Astro-News. Every student will be expected to give a 3-5 minute presentation during Astro-News (only one presentation per student over the entire course). The presentation may be in PowerPoint, keynote, overhead or blackboard. Astro-News will cover events that have been recently presented in a recognized astronomy media source.

Great sources of astronomy news include:

(a) the Science Section of the New York Times

(see http://www.nytimes.com/pages/science/index.html),

(b) the NASA News Website

(see http://www.nasa.gov/news/index.html),

(c) the Hubble Space Station News website

(see http://hubblesite.org/newscenter/),

(d) the Sky and Telescope news site

(see http://www.skyandtelescope.com/news), and

(e) the spaceweather website

(see http://www.spaceweather.com/).

Midterm Exams Homework and Quizzes:

There will be 3 midterm exams over the semester. A quiz will be given at the end of each class. The quizzes will be based on material already presented in lectures. There will be a final exam that will cover most of the material presented in the lectures.

Class and Attendance Policies:

Cellular technology: Please respect your class-mates and keep your cellular devices off. You are expected to attend all classes.

College of Charleston Honor Code and Academic Integrity:

Lying, cheating, attempted cheating, and plagiarism are violations of our Honor Code that, when identified, are investigated. Each incident will be examined to determine the degree of deception involved.

Incidents where the instructor determines the student-s actions are related more to a misunderstanding will be handled by the instructor. A written intervention designed to help prevent the student from repeating the error will be given to the student. The intervention, submitted by form and signed both by the instructor and the student, will be forwarded to the Dean of Students and placed in the student-s file.

Cases of suspected academic dishonesty will be reported directly by the instructor and/or others having knowledge of the incident to the Dean of Students. A student found responsible by the Honor Board for academic dishonesty will receive a XF in the course, indicating failure of the course due to academic dishonesty. This grade will appear on the student-s transcript for two years after which the student may petition for the X to be expunged. The F is permanent. The student may also be placed on disciplinary probation, suspended (temporary removal) or expelled (permanent removal) from the College by the Honor Board.

Students should be aware that unauthorized collaboration--working together without permission-- is a form of cheating. Unless the instructor specifies that students can work together on an assignment, quiz and/or test, no collaboration during the completion of the assignment is permitted. Other forms of cheating include possessing or using an unauthorized study aid (which could include accessing information via a cell phone or computer), copying from others- exams, fabricating data, and giving unauthorized assistance.

Research conducted and/or papers written for other classes cannot be used in whole or in part for any assignment in this class without obtaining prior permission from the instructor.

Students can find the complete Honor Code and all related processes in the Student Handbook at http://studentaffairs.cofc.edu/honor-system/studenthandbook/index.php
