Introduction to Data Science as a Pathway to Further Study in Computing

Abstract

Several institutions have recently introduced Introduction to Data Science courses that involve a substantial programming component and do not require CS1 as a prerequisite. Programming and computational thinking are central to the emerging discipline of data science, and so there is overlap between traditional CS1 courses and Introduction to DS.Partly because of the evident societal significance of data science and because data science does not have the problematic reputation of computer science, Intro to DS can attract new and diverse audiences that may not have been interested in taking CS1.We explore Intro to DS as a possible alternative path into computing: what are the learning goals in Intro to DS that involve programming and/or computational thinking? How generalizable are the problems students solve in Intro to DS to what students would encounter in future studies? Is it feasible for students to pursue a data science sequence rather than CS1-CS2 and be prepared for a career that uses data science? To what extent can a pathway through a data science sequence diversify the population of students who graduate from degree programs in computer science and data science?We survey the Introduction to Data Science courses offered in North American post-secondary education, and focus on a data science sequence that uses the R programming language and does not require CS1 at an R1 institution as a case study.
