Syllabus Description (from Canvas):

Astronomy 101: Introduction to Astronomy

The sky connects people across cultures, time, and space, and inspires us to wonder what's up there, where it all came from, and what will happen in the future. In Astro 101 you'll learn modern answers to these ancient questions, work with astronomical data, and even direct a robotic telescope!

This course has been taught online since 2012, always in an asynchronous mode (i.e. few live meetings). If you prefer scheduled lectures, please consider the excellent A sections of Astro 101 or 150. All of these courses are open to everyone, and there are no prerequisites. We do not assume or require an unusual scientific or mathematical background, but we do expect you to remember how to use scientific notation and algebra, as well as office software (e.g. Word, Powerpoint, or Google Docs). If you do not have access to these tools, please make a point of speaking with your instructor as soon as possible. 

Required Materials

  • Astronomy: At Play in the Cosmos 2nd edition, Adam Frank. W.W. Norton

We've organized this course around this textbook because it presents astronomy as a story about people--because it is! You can buy the textbook from various sources, but the print version is expensive because it includes access to resources we don't need. Instead, I recommend the ebook, available from W.W.Norton for (as of early 2024) $39.95. The first three chapters are free, so you can try it out. The first edition of the text will also work--most things are in the same order--but there are a few big typos which I've listed here: At Play in the Cosmos first edition Errata.

Things to Know

  • Weekly Lessons: This course unfolds over nine lessons, which you can view by navigating to Modules.
  • Assignments: Lessons include ungraded activities, including mini-lectures with practice problems and lesson self-checks, but the graded assignments are just the discussions and labs.
  • Due Dates: Canvas will automatically assign a zero to late assignments, even if they are turned in a second late. We're not worried about seconds, but we do expect your work to be submitted in a timely fashion. We cannot guarantee that we will grade late work. If you miss a due date due to a family emergency, sickness, or other short term situation, please get in touch with your TA when you are again able to participate in school.
  • Make-Up Assignments, Redos, and Extra Credit: We do not offer make-ups, redos, or extra credit.
  • Announcements and Contacting Us: We will use Canvas Announcements to send out important information; you are expected to check these on a regular basis throughout the week. If you need to contact us, follow these directions so we can respond to you in a timely manner:
    • For questions about the course, or course content, post a message on the General Discussion Forum, or come to office hours. Our times are listed on the Instructor and TA Contact Information page.
    • For questions about grading, first check the rubric, then come to office hours. If you leave a submission comment after we've graded your assignment, we won't see it. 
  • Academic honesty: Collaboration is not allowed on quizzes or exams. While you are allowed and encouraged to work with members of the class on other assignments, in all cases your work should be in your own words. If you used other people's work, you must cite it. If you used generative AI tools, such as ChatGPT, you must include the response from the tool alongside your own work, which we expect will express ideas beyond those generated by the tool. If we suspect academic misconduct, I will withhold your grade and report the suspected activity to Community Standards & Student Conduct.
  • The University of Washington Department of Astronomy does not tolerate harassment of any kind: Harassment is any behavior by an individual or group that contributes to a hostile, intimidating, unwelcoming, and/or inaccessible work environment. Anyone can experience harassment. If you believe that you are being harassed, please reach out to your instructor and/or SafeCampus.
  • We Follow UW Policies: We follow the UW's guidelines for faculty, including not requiring notes from doctors. For a full list, see UW Syllabus Guidelines and Resources.

Accommodations & Support

Support is available to discuss safety and well-being 24 hours / 7 days a week through SafeCampus. Accommodations for temporary health conditions and permanent disabilities are organized through UW DRS.

Washington state law requires that UW develop a policy for accommodation of student absences or significant hardship due to reasons of faith or conscience, or for organized religious activities. The UW’s policy, including more information about how to request an accommodation, is available at Religious Accommodations Policy. Accommodations must be requested within the first two weeks of this course using the Religious Accommodations Request form.

Evaluation and Grading

Exams -- 30% of your grade

There are two timed, multiple-choice exams. The Unit 1 Exam will test content from the first half of the class, while the Unit 2 Exam will focus on the second half of the class. See About the Quizzes and Exams for more information.

Quizzes -- 30% of your grade

There are three written quizzes, each of which focuses just on the previous two lessons; they come at the end of Lessons 2, 4, and 7. See About the Quizzes and Exams for more information.

Labs -- 20% of your grade

In the labs you will work with real data from the Sloan Digital Sky Survey (SDSS). The last lab will give you a chance to choose your own astronomical experience, including directing a telescope to take observations for you!

Discussions -- 20% of your grade

Credit will be based on the quality and timeliness of your posts and responses. Your first post in each discussion is due before the due date, read About the Discussions for how this work, but you must participate throughout each week for full credit. We understand that occasionally you will not be able to participate fully in each discussion, so we set Canvas to drop your lowest discussion score automatically.

Final Grade

Your final grade is determined by transforming your overall percentage to the 4.0 scale. A percentage score of at least 60% is required for credit. A score of 72% guarantees a 2.0 or higher, an 82% guarantees a 3.0 or higher, and a 95% guarantees a 4.0. If you have chosen Satisfactory/Not-Satisfactory grading you will need a 2.0 or better to receive credit.
