Course Overview and Learning Objectives

This is an exciting time to be a social scientist and especially a Communication scholar! An increasing amount of our lives---and our interactions---are stored digitally. Social scientists are increasingly using that data to ask and answer questions about how the social world works. I firmly believe that computational tools have created a new frontier in the social sciences which those who develop computational skills can explore.

This class is an introduction into that world. The course is intended to give students an introduction to programming principles, the Python programming language, and data science tools and approaches. However, this is not a computer science class or a statistics class, and no prior programming experience is required or expected. We will focus on gaining access to data and basic data manipulation rather than complex statistical methods.

The main goal of the class is to help you to complete a preliminary, independent, data-centric project. As part of this project, you (on your own or in a team) will write software to collect data from web APIs, process and clean that data, and produce statistics, hypothesis tests, and graphical visualizations that address questions you are interested in.

I will consider this class a complete success if, at the end, every student can:

  • Write or modify a program to collect a dataset from a publicly available data source.
  • Read web API documentation and write Python software to parse and understand a new and unfamiliar web API.
  • Understand and follow basic version control practices.
  • Use digital data to effective answer a substantively interesting question and to present this data effectively in the context of both a formal presentation and a written report.
  • Identify multiple ways that computational approaches are being used for social science research.
  • Feel comfortable taking more advanced computational methods courses or learning new techniques on your own.


Required resources and texts

Laptop

Windows, Mac OS, and Linux are all fine but an iPad or Android tablet won't work. We're going to install software during the class that requires about 5GB of extra space and you'll be working on projects for homework. For the classroom assignments, nothing is terribly intensive, but your own data collection could tax the resources of an older machine.

If for some reason your laptop dies mid-course, please contact me so we can get your new one up to speed.

Readings

I will list required chapters in the schedule below. In general, you should expect to spend far more time working on programming tasks than reading. Much like math or other technical courses, this course will build on itself every day. You should make every effort to cover the reading and exercise material every day in preparation for the next day.

  • Other readings: Throughout the module we will read and discuss examples of computational social science that I find particularly well done or interesting. Many are available through the Purdue library. I will also make all of them available on Brightspace. If you come across additional examples that you think the class would benefit from, please suggest them to me.
  • Optional readings: Matthew Salganik's book 'Bit by Bit: Social Research in the Digital Age' is a wonderful introduction to computational social science. We will not be discussing it in class but I highly recommend it.

Course logistics

Note About This Syllabus

This is my first time teaching this course as a summer module. Although the core expectations for this class are fixed, the details of readings and assignments may shift based on how the class goes. As a result, there are three important things to keep in mind:

  1. Although details on this syllabus will change, I will not change readings or assignments less than three days before they are due. If you plan to read more than three days ahead, contact me first.
  2. Closely monitor your email. Because this a wiki, you will be able to track every change by clicking the history button on this page. I will also summarize these changes in an announcement that will be emailed to everybody in the class.
  3. I will ask the class for voluntary anonymous feedback frequently. Please let me know what is working and what can be improved.

Lectures

This is an online course and I am not requiring any synchronous participation. I am planning to hold an online lecture from approximately 10 am - 11 am every day at meet.jit.si/COM674, where I introduce the concepts for the upcoming reading and assignment. I will record these lectures and will upload them to Brightspace. Following the lecture, I will stick around to answer questions as folks begin working on the coding challenges.

I highly encourage those who can attend synchronously to do so. In general, my teaching style is more conversational than a formal lecture. I prefer that students feel they can "politely interrupt" at any time to seek clarification or make a well-informed point, and the lectures will be much better if I can get real-time feedback about what is and isn't making sense.

Office hours and email

  • I will hold office hours by appointment. If you come with a programming question, I will expect that you have already tried to solve it yourself in multiple ways and that you have discussed it with a classmate. This policy lets me have time to help more students, but it's also a useful strategy. Often just trying to explain your code can help you to recognize where you've gone wrong.
  • I am also available by email. You can reach me at jdfoote@purdue.edu. I try hard to maintain a boundary between work and home and I typically respond only on weekdays during business hours (~9-5) but during the week I will generally respond within 24 hours.

Assignments

There will be three main types of assignments. Each is discussed in detail below but here is a brief summary:

  1. Research Project: The main outcome of this course will be a research project exploring a social science question using Python, and the bulk of your grade will be based on that project. Submit these via Brightspace
  2. Coding Challenges: There will be daily programming assignments that I will ask you to turn in on Brightspace but which will only be graded as complete/incomplete. I will also randomly assign someone to present their solution to each of the problems, on [

piazza.com/purdue/summer2020/com674 Piazza].

  1. Paper Discussion: Each day we will read and discuss a paper which uses computational approaches to address social science questions.

Research project

As a demonstration of your learning in this course, you will design and carry out a quantitative research project, start to finish. This means you will all:

  • Design and describe a plan for a study — The study you design should involve quantitative analysis and should be something you can complete at least a first pass on during this module.
  • Find a dataset — You should very quickly identify a dataset you will use to complete this project.
  • Analyze, visualize, report, and interpret your data — You will do this in both a short paper and a short presentation.
  • Ensure that your work is replicable — You will need to provide code and data for your analysis in a way that makes your work replicable by other researchers.

I strongly urge you to produce a project that will further your academic career outside of the class. There are many ways that this can happen. Some obvious options are to prepare a project that you can submit for publication, that you can use as pilot analysis that you can report in a grant or thesis proposal, and/or that fulfills a degree requirement. I prefer that you do projects on your own but it may be possible to work as a small team (maximum 3 people). Team projects are expected to be more ambitious than individual projects. Preliminary assignments will help you to develop your idea and to get feedback from me and others.

There are several intermediate milestones and deadlines to help you accomplish a successful research project. Unless otherwise noted, all deliverables should be submitted via Brightspace.

Project idea and dataset identification

Due date
May 20
Maximum length
500 words (~1-2 pages)

Early on, I want you to identify and describe your final project. Your description should be short and can be either paragraphs or bullets. It should include the following:

  • An abstract of the proposed study including the topic, research question, theoretical motivation, object(s) of study, and anticipated research contribution.
  • An identification of the dataset you will use and a description of the columns or type of data it will include. If you do not currently have access to these data, explain why and when you will.
  • A short (several sentences) description of how the project will fit into your career trajectory.

Project planning document

Due date
May 29
Maximum length
~4-5 pages

The project planning document is a basic shell/outline of an empirical quantitative research paper. The planning document should focus around three big questions:

  • Why are you planning to do this analysis? Make sure to introduce any background information about the topic, the community, your business, or anything else that will be required to properly contextualize your study.
  • How will you get the data to analyze? Describe the data sources will you collect and how they will be collected.
  • How will you analyze the data? Describe the visualizations, tables, or statistical tests that you will produce.

One approach that I have found helpful is outlined on this wiki page.

Project presentation and report

Report due date
June 12
Maximum length
4000 words (~15 pages)
Presentation due date
June 11
Maximum length
8 minutes

The project report

You will craft a Jupyter Notebook that will ideally provide the foundation for a high quality short research paper that you might revise and submit for publication. I do not expect the report to be ready for publication, but it should contain polished drafts of all the necessary components of a scholarly quantitative empirical research study. In terms of the structure, please see the page on the structure of a quantitative empirical research paper.

The great thing about a Jupyter Notebook is that it allows you to provide data, code, and any documentation sufficient to enable the replication of all analysis and visualizations. If that is not possible/appropriate for some reason, please talk to me so that we can find another solution.

Because the emphasis in this class is on methods and because I'm not an expert in each of your fields, I'm happy to assume that your paper, proposal, or thesis chapter has already established the relevance and significance of your study and has a comprehensive literature review, well-grounded conceptual approach, and compelling reason why this research is important. As a result, you need not focus on these elements of the work in your written submission. Instead, feel free to start with a brief summary of the purpose and importance of this research followed by an introduction of your research questions or hypotheses. If you provide more detail, that's fine, but I won't give you detailed feedback on these parts and they will not figure prominently in my assessment of the work.

Jupyter Notebooks do not have all of the tools for citations that Word or LaTeX or even Google Docs have, so while I expect you to cite related work it is OK if it isn't as polished as citation management software would make it.

The presentation

The presentation will provide an opportunity to share a brief summary of your project and findings with the other members of the class. However, don't treat it as a comprehensive overview of your paper: I would rather you tell a subset of the story well than the whole story in a rushed fashion. For instance, you can give a completely successful presentation by describing the motivation and walking through one plot in your paper. Since you will all give other research presentations throughout your career, I strongly encourage you to take the opportunity to refine your academic presentation skills.

All presentations will need to be a maximum of 8 minutes long. Concisely communicating an idea in the time allotted is an important skill in its own right. I am still working on finding the right software for doing these, but I think we will likely use FlipGrid.

Daily Coding Challenges

Nearly every day I will give you a set of coding challenges before the end of class that will involve writing code or adding to code that I've given you. These coding challenges will be turned in on Brightspace but will not be graded. I encourage you to work together on these challenges but to make sure that you understand the concepts yourself.

Each day I will randomly select a set of students to share their solutions to a selected exercise on [piazza.com/purdue/summer2020/com674 Piazza], at least one hour before the next day's lecture starts. I encourage you to also use Piazza to ask and answer each other's questions as you work on the assignments. We will use some of our lecture time to review the problems and I will make sure that a correct solution is posted by the end of that day. As you will see over the course of the module, there are many possible solutions to many programming problems and my own approaches will often be different than yours. That's completely fine! Coding is a creative act!

DataCamp

DataCamp is an online coding education site, with lots of great resources about Python. I set up our class for free access for six months - you can sign up at this link.

I will put a few courses as assignments on DataCamp which will be optional. I'll signal when you might want to do these courses in the schedule.

Paper Discussions

Every day we will review a paper that uses computational methods. On the first day, I will ask you to sign up to lead the discussion two times. When leading the discussion, you will post a video explaining the paper and asking a few discussion questions to Brightspace. Everyone else will respond with their thoughts about the paper.

Reflection papers

As discussed in more detail below, two times during the course I will ask you to respond to a set of reflection questions. These questions are intended to help you to think about what you have learned and accomplished and to craft goals for the remainder of the course. They are also an important way for me to gather feedback about how the course is going so that I can adjust.

Grades

This course will follow a "self-assessment" philosophy. I am more interested in helping you to learn things that will be useful to you than in assigning grades. The university still requires grades, so you will be leading the evaluation of your work. This will be completed with me in four stages, at the end of weeks 4, 8, 12, and 16. In each stage, you will reflect on what you have accomplished thus far, how it has met, not met, or exceeded expectations, based both on rubrics and personal goals and objectives. At each of these stages you will receive feedback on your assessments. By the end of the semester, you should have a clear vision of your accomplishments and growth, which you will turn into a grade. As the instructor-of-record, I maintain the right to disagree with your assessment and alter grades as I see fit, but any time that I do this it will be accompanied by an explanation and discussion. These personal assessments, reflecting both honest and meaningful reflection of your work will be the most important factor in final grades.

I suggest that we use the following rubric in our assessment:

  • 15%: class participation, including attendance, participation in discussions and group work, and significant effort towards weekly assignments.
  • 5%: Final Project Idea.
  • 10%: Final Project Proposal.
  • 50%: Final Project paper/Jupyter notebook.
  • 20%: Final Presentation including your slides and presentation.

My interpretation of grade levels (A, B, C, D/F) is the following:

A: Reflects work the exceeds expectations on multiple fronts and to a great degree. Students reaching this level of achievement will:

  • Do what it takes to learn the programming principles and techniques, including looking to outside sources if necessary.
  • Engage thoughtfully with an ambitious research project.
  • Take intellectual risks, offering interpretations based on synthesizing material and asking for feedback from peers.
  • Sharing work early allowing extra time for engagement with others.
  • Write reflections that grapple meaningfully with lessons learned as well as challenges.
  • Complete most, if not all programming assignments at a high level.

B: Reflects strong work. Work at this level will be of consistently high quality. Students reaching this level of achievement will:

  • Be more safe or consistent than the work described above.
  • Ask meaningful questions of peers and engage them in fruitful discussion.
  • Exceed requirements, but in fairly straightforward ways - e.g., an additional post in discussion every week.
  • Compose complete and sufficiently detailed reflections.
  • Complete many of the programming assignments.

C: This reflects meeting the minimum expectations of the course. Students reaching this level of achievement will:

  • Turn in and complete required assignments on time.
  • Be collegial and continue discussion, through asking simple or limited questions.
  • Compose reflections with straightforward and easily manageable goals and/or avoid discussions of challenges.
  • Not complete programming assignments or turn some in in a hasty or incomplete manner.

D/F: These are reserved for cases in which students do not complete work or participate. Students may also be impeding the ability of others to learn.

Administrative Notes

Attendance Policy

Attendance is very important and it will be difficult to make up for any classes that are missed. It is expected that students communicate well in advance to faculty so that arrangements can be made for making up the work that was missed. It is the your responsibility to seek out support from classmates for notes, handouts, and other information.

Incomplete

A grade of incomplete (I) will be given only in unusual circumstances. The request must describe the circumstances, along with a proposed timeline for completing the course work. Submitting a request does not ensure that an incomplete grade will be granted. If granted, you will be required to fill out and sign an “Incomplete Contract” form that will be turned in with the course grades. Any requests made after the course is completed will not be considered for an incomplete grade.

Academic Integrity

While I encourage collaboration, I expect that any work that you submit is your own. Basic guidelines for Purdue students are outlined here but I expect you to be exemplary members of the academic community. Please get in touch if you have any questions or concerns.

Nondiscrimination

I strongly support Purdue's policy of nondiscrimination (below). If you feel like any member of our classroom--including me--is not living up to these principles, then please come and talk to me about it.

Purdue University is committed to maintaining a community which recognizes and values the inherent worth and dignity of every person; fosters tolerance, sensitivity, understanding, and mutual respect among its members; and encourages each individual to strive to reach his or her own potential. In pursuit of its goal of academic excellence, the University seeks to develop and nurture diversity. The University believes that diversity among its many members strengthens the institution, stimulates creativity, promotes the exchange of ideas, and enriches campus life.

Students with Disabilities

Purdue University strives to make learning experiences as accessible as possible. If you anticipate or experience physical or academic barriers based on disability, you are welcome to let me know so that we can discuss options. You are also encouraged to contact the Disability Resource Center at: drc@purdue.edu or by phone: 765-494-1247.

Emergency Preparation

In the event of a major campus emergency, I will update the requirements and deadlines as needed.

Mental Health

If you or someone you know is feeling overwhelmed, depressed, and/or in need of mental health support, services are available. For help, such individuals should contact Counseling and Psychological Services (CAPS) at 765-494-6995 during and after hours, on weekends and holidays, or by going to the CAPS office of the second floor of the Purdue University Student Health Center (PUSH) during business hours.

Acknowledgements

This course is heavily based on earlier courses taught by Tommy Guy and Mako Hill at the University of Washington as well as a course taught by Laura Nelson at Northeastern University.
