ABCD Class 수업 현장 - 여의도여고

ABCD Class

ABCD Class is a school-ready data science education service organized into AI, Big Data, Coding, and Domain Projects so middle and high school students can build the capabilities demanded in an AI & Data society. It brings advanced data science concepts, once taught mostly in higher education, down to a level students can truly understand.

Data science is not only for students on a STEM track. While it may seem math- or computer-heavy at first glance, ABCDEdu's mission is grounded in the belief that these programs can have even greater impact for students from humanities and interdisciplinary backgrounds. We tailor depth, pacing, and content to each school's goals, schedule, and learner profile through customized courses.
