Software and Platforms

All assignments in this course will be scripted and analyzed using Python . All of my demos will use Jupyter Notebooks as a programming environment. You are welcome to use Jupyter Notebook , JupyterLab , or any other Integrated Development Environment (IDE) of your choice when writing code. Most assignments, however, will require you to turn in a .py or .ipynb file and/or a written document (.docx, .pdf). Many assignments will require specific Python dependencies, such as a particular module or library, so it is recommended that you install the Anaconda platform, which includes Python , Jupyter Notebooks , and most if not all of the libraries we will use. Lastly, for our unit on relational databses, we will use the desktop software DB Browser for SQLite , which is free to download and use.

Assignments will be shared via GitHub Classroom , which provides a collaboration and version control system via Github . Typically, Github Classroom assignments will contain datasets, assignment template files and/or starter code. In some cases, if a dataset is too large for Github 's file size limits, assignments will come with instructions on how to download the data online, or from a Google Drive folder. Completed assignments will be turned in for grading on Canvas , and all grades and student feedback will be issued on Canvas in order to maintain educational privacy.

Grading and Feedback

As a general rule, the expectations in this course are high, and I'm confident you can all do great work. The feedback I provide on assignments is designed to help you get there. My goal is to provide specific, relevant, and honest feedback when I grade your work. This will include constructive criticism, strategies for improvement, and guidance on how students can achieve success. I will not do "compliment sandwiches" just to begin and end on a positive remark, but this means that, when I praise your work, it's an honest (and I think more meaningful) act of praise.

Grade Breakdown

Attendance and Timeliness

In a liberal arts context, it is particularly important that students arrive on time and come prepared to engage with the community we will be building in our classroom. I expect you to attend class every class meeting, and I expect you to arrive on time. Attendance will be taken every day. If you cannot attend class, it is your responsibility to get (from a classmate) all written notes about what we discussed in class, including in-class announcements.

Note: Late arrival counts as half an absence. If you have a commitment immediately before this class that will force to come late (say, a class in Mitchell) you should either drop that class or drop this one.

Since regular attendance is a prerequisite to passing this course, missing more than five classes will result in an additional penalty of -5% from your final course grade for each unexcused absence beyond the fifth.

Participation and Distractions

Participation will be assessed using a mix of preparedness, speaking during class discussions, remaining attentive during lectures, and completing in-class assignments. An unexcused absence will result in a participation score of zero for the day, and coming late will result in a maximum participation score of 50 for the day.

Creating distractions in class is especially frowned upon. Disruptions such as falling asleep, leaving class excessively, and talking over the professor are frowned upon. Cell phones should be off and put away. Laptops are okay for notes and such but, when laptops are being used, you should not be messaging, using Facebook, etc. In the event of a disruption, I will typically give a verbal warning for your first offense. After that, I reserve the right to ask you to leave class and mark you absent for the day.

Late Work

If you have a legitimate emergency such as a serious illness, a mental health emergency, or a death in the family, I will grant an appropriate extension with a new due date. The trade off is that work turned in this way is probably not going end up in my hand when I grade everything else, so it's going to get very sparse feedback. If you miss a deadline entirely without getting an extension, you will automatically lose 10 points off the top of your grade for each day it is late, in addition to any points you lose for the quality of the work. Retroactive and last-minute extensions will not be granted.

Being Prepared for Class

Coming to class prepared means that you have the day's reading in hand (printed or digital) and have come to class with a way to take notes (printed or digital). If you are not prepared for class, I reserve the right to grade as if you were absent for that day. Anything due on a given day is due at the start of class. Any digital submission of material is due by the time class starts on the day the hard copy is due.

Disability Resources

If you are a student who feels you may need an accommodation based on the impact of a disability, you should contact me privately as soon as possible to discuss your specific needs. I rely on the Academic Resource Center in 020 Higley Hall to verify the need for reasonable accommodations based on documentation on file in that office.

Peer Learning Strategists Program

The Peer Learning Strategists (PLS) program was developed by Denison students and faculty for those in introductory science classes. It is an initiative of a larger program called RAISE (Readiness and Inclusion in Science Education) and is a great resource to learn how to study more efficiently and learn more effectively. The PLS program employs peer-to-peer mentoring focused on teaching overarching learning strategies crucial to success in college science classes. Trained science majors work as PLS mentors to help hone your learning approach since skills most helpful in college often differ from skills that led to high achievement in high school. Students meet one-on-one with a PLS mentor one hour weekly for at least three weeks with some students continuing beyond the three-sessions recommendation. PLS mentors are not tutors, content is not course-specific, and conversations provide space for attaining skills for lifelong learning and success. Contact Science Initiatives Coordinator Jeni Miller or Dr. Melanie Lott with additional questions.

Academic Integrity

Proposed and developed by Denison students, passed unanimously by DCGA and DenisonÕs faculty, the Code of Academic Integrity requires that instructors notify the Associate Provost of cases of academic dishonesty. Cases are typically heard by the Academic Integrity Board, which determines whether a violation has occurred, and, if so, its severity and the sanctions. In some circumstances the case may be handled through an Administrative Resolution Procedure. Further, the code makes students responsible for promoting a culture of integrity on campus and acting in instances in which integrity is violated.

Academic honesty, the cornerstone of teaching and learning, lays the foundation for lifelong integrity. Academic dishonesty is intellectual theft. It includes but is not limited to providing or receiving assistance in a manner not authorized by the instructor in the creation of work to be submitted for evaluation. This standard applies to all work ranging from daily homework assignments to major exams. Students must clearly cite any sources consulted--not merely for quoted phrases, but also for ideas and information that are not common knowledge. Neither ignorance nor carelessness is an acceptable defense incases of plagiarism. It is the studentÕs responsibility to follow the appropriate format for citations. Students should ask their instructors for assistance in determining what sorts of materials and assistance are appropriate for assignments and for guidance in citing such materials clearly.

Note on Technology: Unauthorized use of technology (including, but not limited to, artificial intelligence sites and translation programs) in the preparation or submission of academic work can be considered a form of cheating and/or plagiarism. Instructors may at their discretion create assignments that incorporate the use of supporting technologies and will inform students of acceptable uses of technology in their courses. It is the responsibility of the student to ask the instructor for clarification whenever they are unclear about the parameters of a specific assignment and to understand that presenting the work of artificial intelligence as your own constitutes a violation of Denison's Code. Cases of suspected inappropriate use of technology may be submitted to the Academic Integrity Board to initiate an investigation of academic dishonesty.

Our Commitment to Liberal Arts Education

Denison's mission statement articulates an explicit commitment to liberal arts education. It emphasizes active learning, which defines students as active participants in the leaning process, not passive recipients. Denison seeks to foster self-determination and to demonstrate the transformative power of education. A crucial aspect of this approach is what Denison's mission statement refers to as "a concern for the whole person," which is why the university provides a "living-learning environment" based on individual needs and an overriding concern for community. This community is based on "a firm belief in human dignity and compassion unlimited by cultural, racial, sexual, religious or economic barriers, and directed toward an engagement with the central issues of our time."

In this class, we will discuss inequality directly. In many cases, you will asked to apply quantitative reasoning skills to these subject, which can be difficult because there is always the potential for the available data to complicate or contradict something you may feel very passionate about. In these cases, you should aspire to adopt an attitude of critical skepticism, i.e. wary of claims that are not supported by evidence but potentially willing to be persuaded by evidence if you find it compelling, and willing to give that evidence a fair hearing.

How we treat one another will be a cornerstone of these conversations. Denison's "Guiding Principles" speak of "a community in which individuals respect one another and their environment." Further, "each member of the community possesses a full range of rights and responsibilities. Foremost among these is a commitment to treat each other and the environment with mutual respect, tolerance, and civility." It's easy to treat someone this way when you like them and agree with their ideas, but the real challenge is treating those who differ from us with the same compassion and respect. However, I consider disruptive, deceitful, or hateful behavior to be breaches of these responsibilities. Bullying, trolling, hate speech, and harassment of any kind will not be tolerated.

Discrimination, Sexual Misconduct, and Sexual Assault

Essays, journals, and other coursework submitted for this class are generally considered confidential pursuant to the UniversityÕs student record policies. However, students should be aware that University employees are required by University policy to report allegations of discrimination based on sex, gender, gender identity, gender expression, sexual orientation or pregnancy to the Title IX Coordinator or a Deputy Title IX Coordinator. This includes reporting all incidents of sexual misconduct, sexual assault and suspected abuse/neglect of a minor. Further, employees are to report these incidents that occur on campus and/or that involve students at Denison University whenever the employee becomes aware of a possible incident in the course of their employment, including via coursework or advising conversations. There are others on campus to whom you may speak in confidence, including clergy and medical staff and counselors at the Wellness Center. More information on Title IX and the UniversityÕs Policy prohibiting sex discrimination, including sexual harassment, sexual misconduct, stalking and retaliation, including support resources, how to report, and prevention and education efforts, can be found at: https://denison.edu/campus/title-ix .
