Readings

Students will read approximately 15 pages per week of academic material during the semester. All academic readings will be linked to the course website. There are no textbooks that need to be purchased for this course.

Assignments

  1. Quizzes (20%)
  2. Participation (20%)
  3. Homework Assignments (20%)
    1. Online Blackboard Quizzes (10%)
    2. Coding Assignments (10%)
  4. Final project (40% of final grade)

Quizzes

Students will complete approximately ten graded quizzes. These are designed to check understanding of key data science concepts. I will drop your lowest two quiz scores so you do not have to worry about making up missed quizzes.

Participation

Participation in Data Science for All is expected. Students will earn credit through in-class activities. While there are no drops for missed participation, a syllabus quiz and 1–2 feedback surveys will also count toward this grade and can replace a missed day. Participation makes up a maximum of 20% of the course grade.

Homework Assignments

Students will complete 4–5 coding assignments and routine online quizzes. Coding assignments provide guided practice in R programming and data analysis, while online quizzes reinforce current material and help prepare for in-class quizzes.

Online quizzes will be delivered through Blackboard. They are untimed and allow multiple attempts (with the score averaged) before the deadline. Coding assignments will be released one week before they are due; online quizzes will be available 24 hours before their deadline. Be sure to read instructions early so you have time to ask questions.

Final Project

The course will conclude with a group final project that applies the skills developed throughout the semester. Students will work collaboratively to design and execute an original data analysis, and will present their findings in both a professional written report and a presentation.

Course Help

Office hours

The purpose of office hours is primarily to discuss/clarify course concepts and for us to provide homework-related hints. You can drop in on any of the listed course instructors office hours without letting us know beforehand. Mine will be held in-person, unless there’s an exception. For more private matters, it’s best to make an appointment with me in advance to ensure privacy. For data science advising questions there are additional office hours here.

Email

Include “[DATS 1001]” at the beginning of the subject line of your email. If you have a question related to course materials, email me and the TAs from your lecture. I’ll check my emails every weekday at 8:30 and 16:30. When emailing, address your professors properly. For me, “Prof. Burnett” is preferred.

Data Science Help Desk

The Data Science Program has a help desk located in Samson Hall 304. They will have someone available for tech and coding related help on weekdays from 11:00-16:00 starting after week 3. This will also be where the teaching assistants will hold office hours.

Tutoring

GWU Academic Commons offers peer tutoring. They provide free, one-on-one support from trained undergraduate tutors who have successfully completed the courses they support, including this course. You can book an appointment for peer tutoring here starting Sept. 2.

Policy on AI Tools

You are encouraged to reuse any code snippets provided by me, your TAs or in the course materials, as well as assistance received during office hours and GW tutoring. However, all graded assignments must be your own work. This includes work that is free from unauthorized assistance, including from other people or generative AI tools.

Because we want to maximize your learning in this course, you are not permitted to use AI-based technology (like ChatGPT and Copilot) to write code for your assignments. It is often very clear to instructional staff when AI has been used by a student to solve a problem, especially because the AI algorithm is aware of content beyond the scope of the course. If you use AI to solve homework problems, your work will be reported to the Office Of Student Conduct. For the same reasons as mentioned, you are not allowed to paste code that was found through Googling or found on StackOverflow or Chegg. Solutions that make use of code found on the internet will be reported to the Office Of Student Conduct.

Take care not to use AI or Large Language Models (LLMs) to produce work you want to claim to be your own. One way to think of LLMs is as a tutor or classmate. What would it be appropriate to ask a tutor or classmate for help with? What would you not be permitted ask a tutor or classmate for help with?

You are allowed to discuss homework with other students in the class. However, you are not allowed to share your code or assignments. The work you submit should be original. Unreasonably similar or excessive solutions will be reported to the Office Of Student Conduct.
