Undergraduate Course Descriptions

How do new ideas spread online? Why do some take off and others fail? What determines when people will cooperate and when they will be selfish? Where do our social norms come from, and what happens when they are disrupted – as they were during the first year of the pandemic? Why is communicating about climate change so challenging? How can we make our corporate and university research teams more intelligent? The last decade in social science has seen remarkable breakthroughs in our answers to these and other profound questions about societal communication and evolution. One of the most powerful and influential tools behind these breakthroughs is Web-based social experiments. This course unveils the exciting new world of building Web-based experiments to study human collective behavior. Students will learn the big ideas behind Web-based experimental design, which will prepare them to understand the latest scientific breakthroughs in the study of social and cultural evolution, and even to design their own Web-based studies. This class does not involve coding and no programming experience is necessary. Instead, students will be introduced to a range of new experimental approaches, and will learn how they produce results that guide the policies that are currently used by governments, universities and corporations. This course will show you the science behind the big ideas and simple rules that are used to predict the future of our economy, our society and our culture.

Acquiring and demonstrating data literacy, namely, the ability to find, appropriately handle, analyze, and communicate insights from the rapidly growing spectrum of data in all aspects of modern life, is now a vital skill for virtually all workers and researchers. This course provides a foundation in the concepts, methods, and applications of data science (including network science) to questions in Communication. The course will build data literacy and help you start to develop skills working with large and complex datasets of relevance to communication behaviors in the digital world. Students will become familiar with basic programming skills for data analysis using the R and Python programming languages, along with some of the common tools used for network and data analysis and visualization. It will provide an introduction and overview of the key elements of applied data science, including the analysis of networks and machine learning (ML). The practical and ethical challenges of 'big data' and the increasing use of algorithmic (ML) decision systems will also be explored. No prior programming or data analysis experience is required.

In this 'big data' era, presidents and popes tweet daily. Anyone can broadcast their thoughts and experiences through social media. Speeches, debates and events are recorded in online text archives. The resulting explosion of available textual data means that journalists and marketers summarize ideas and events by visualizing the results of textual analysis (the ubiquitous 'word cloud' just scratches the surface of what is possible). Automated text analysis reveals similarities and differences between groups of people and ideological positions. In this hands-on course students will learn how to manage large textual datasets (e.g. Twitter, YouTube, news stories) to investigate research questions. They will work through a series of steps to collect, organize, analyze and present textual data by using automated tools toward a final project of relevant interest. The course will cover linguistic theory and techniques that can be applied to textual data (particularly from the fields of corpus linguistics and natural language processing). No prior programming experience is required. Through this course students will gain skills writing Python programs to handle large amounts of textual data and become familiar with one of the key techniques used by data scientists, which is currently one of the most in-demand jobs.

Today masses of data are available everywhere, capturing information on just about everything and anything. Related but distinct data streams about newsworthy events and issues -- including activity from social media and open data sources (e.g., The Open Government Initiative) -- have given rise to a new source for and style of reporting sometimes called Data Journalism. Increasingly, news sites and information portals present visually engaging, dynamic, and interactive stories linked to the underlying data (e.g., The Guardian DataBlog). This course offers an introduction to Python programming for data analysis and visualization. Students will learn how to collect, analyze, and present various forms of data. Because numbers and their visualizations do not speak for themselves but require context, interpretation, and narrative, students will practice making effective stories from data and presenting them in blogs and other formats. No programming experience is required for this class.

Policy makers, entrepreneurs, and marketers frequently rely on common sense when planning for the future; yet their predictions are often wrong, and their plans fail for reasons that seem obvious after the fact. In this course you will learn about the nature of common sense, when it should be expected to work effectively, and why we are tempted to use it even when we should not. The course will also introduce a data science perspective on explanation, understanding, and decision making, covering topics such as experiments, predictive analytics, forecasting tournaments, scenario planning, and epistemic humility. The course will be conceptual rather than methodological and so is equally appropriate for students with technical and nontechnical backgrounds.

Communication technologies, including the internet, social media, and countless online applications create the infrastructure and interface through which many of our interactions take place today. This form of networked communication opens new questions about how we establish relationships, engage in public, build a sense of identity, promote social change, or delimit the private domain. The ubiquitous adoption of new technologies has also produced, as a byproduct, new ways of observing the world: many of our interactions now leave a digital trail that, if followed, can help us unravel the determinants and outcomes of human communication in unprecedented ways. This course will give you the theoretical tools to critically analyze the impact that networked technologies have on social life and inform your assessment of current controversies surrounding those technologies.

Digital technologies have made communication networks ubiquitous: even when we can't really notice them, they mediate most aspects of our daily activities. Networks, however, have always been the backbone of social life: long before Facebook, Twitter, Snapchat, or other similar platforms, communication created channels for information diffusion that linked people in myriad other ways. Through letters, commerce, or simply face to face interactions, people have always been exposed to the behavior of others. These communicative ties embed us into an invisible web of influence that we can make tangible and analyze. This course will teach you how to map those connections in the form of networks, and how to study those networks so that we can improve our understanding of social life. The goal is to help you grasp the consequences of connectivity, and how small changes in the structure of our ties can lead to big differences in how networks behave.

Increasingly, our daily communications involve responding to and interacting with language produced by artificial intelligence models. On the surface, large language models (LLMs) and generative AI tools (e.g ChatGPT, Bard, etc.) appear to have crossed a milestone in terms of their human-like ability to generate coherent and idiomatic texts. This has significant implications (both positive and negative) for human communication systems and their products, from creative fiction to news, from academic texts to social media content. It also raises many questions around whether we can identify, trust, learn from, and use AI generated language. In this course, we will begin to answer these questions in two ways: 1) Analyzing Key Issues: Drawing upon relevant frameworks in communication and language theory we will explore the transformative nature of AI-generated communication and its impact on individuals and society. 2) Hands-on Application: In parallel, students will acquire skills using Python in implementing machine and deep learning models to better understand how they work and explore their abilities and limitations. We will code various AI models, such as a simple voice assistant, image classifier, misinformation identifier, and a basic text generative application. Through this course students will be equipped for a range of contexts impacted by developments in AI. The course requires students to have a basic experience in Python coding and using Jupyter notebooks.

Algorithms regulate many areas of social life: they shape the information you see online, how resources are allocated, or how hiring and matching happen in private and public settings. In these and many other examples, algorithms rely on data informing the automated decisions they encode. Our ability to think critically about that data is, thus, paramount to understanding how the algorithms operate. In this course, we will discuss how data is transformed into information and actionable knowledge. You will learn how to question data to ensure their validity, reliability, and representativeness. Understanding how data are collected, analyzed, and used is key to being able to demand transparency in automated decision-making, and to exercising our democratic role of demanding accountability when decisions are made based on questionable data.

This course explores the nature of diffusion through social networks, the ways networks are formed and shaped by social structures, and the role they play in health behavior, public policy, and innovation adoption. Topics include: the theory of social networks; the small world model of network structure; constructing models to represent society; the social bases of the adoption of innovations and the spread of new ideas; the role of social networks in controlling changes in public opinion; the emergence of unexpected fashions, fads, and social movements; and the connection between social network models and the design of public policy interventions. Students will learn how to use the agent-based computational modeling tool "NetLogo", and they will work directly with the models to understand how to test scientific theories. We will examine the basic theory of social networks in offline, face-to-face, networks, as well as the role of online networks in spreading new ideas and behaviors through social media. Long standing debates on the effects of social networks on changing beliefs and behaviors, their impact on social change, and ethical concerns regarding their potential manipulation will be given careful consideration throughout. Students will be taught new skills that will enable them to use and develop their own agent-based models.
