This semester, I helped Professor Bergen revamp her freshman seminar, "DATA0150: Data Detectives". She originally developed the seminar with another fellow in Fall 2023; however, this semester’s work involved refreshing aspects of the course based on student feedback and her experience teaching it last fall. The course is not technical; instead, it encourages students to think critically about data and with data. Although there was flexibility in what I could focus on, Professor Bergen and I decided to redesign the course’s final project and develop new in-class activities that would encourage active learning and cross-disciplinary engagement with data science. The final project is now a partner-based blog-like assignment, consisting of 6 different data science-related assignments. Each task requires 900-1500 words and instructs students to create, interact with, and critically analyse data. For instance, while some projects require students to collect online data and make visualisations, others ask students to examine their subscription service data or apply Census data to specific case studies.
