Just-In-Time Prerequisite Review for a Machine Learning Course

We present a just-in-time strategy for prerequisite review in an upper-year machine learning course. This course has a range of prerequistes in math, computer science, and statistics. Prerequisite review is not new, and instructors of this course have historically presented prerequisite resources at the beginning of term. However, some of the materials in these resources are not used until later in the term. With our just-in-time strategy for prerequisite review, we tie prerequisite concepts to each lecture. Before each lecture, students complete 2-4 multiple choice review questions covering these concepts. A short, instructional video is provided with each question, so that if a student is unable to complete the question, they can review the relevant concept by watching the video.
