SIGCSE 2023 - Differentiating for Comfort with Computer Science

As computer science courses grow, instructors may find it increasingly difficult to meet all learners where they are, offering more-experienced students appropriate challenge and less-experienced students sufficient support to become more experienced themselves. In this lightning talk, we present how we've differentiated the instruction and assignments in CS50, Harvard University’s introductory course for majors and non-majors, to support the growing variability we see in students' comfort with computer science. We share how we group students in sections according to their comfort levels, with additional support for those less comfortable in the form of smaller sections. We also share how we designed the course's problem sets for less-comfortable and more-comfortable students alike, ensuring both groups have adequately challenging “floors” and “ceilings.” Our future work includes strengthening support for students who identify as “least comfortable,” whose secondary schools might not have prepared them for studies in computer science or college more generally. We also plan to address questions about assessing students of varying comfort levels, which we presently accomplish through score normalization across comfort levels. *** This is CS50, Harvard University's introduction to the intellectual enterprises of computer science and the art of programming. *** TABLE OF CONTENTS 00:00:00 - Differentiating for Comfort with Computer Science 00:00:11 - Comfort 00:00:47 - Floors and Ceilings 00:01:19 - Assignments 00:01:51 - Sections 00:02:30 - Assessment 00:02:56 - Conclusion *** HOW TO SUBSCRIBE http://www.youtube.com/subscription_center?add_user=cs50tv HOW TO TAKE CS50 edX: https://cs50.edx.org/ Harvard Extension School: https://cs50.harvard.edu/extension Harvard Summer School: https://cs50.harvard.edu/summer OpenCourseWare: https://cs50.harvard.edu/x HOW TO JOIN CS50 COMMUNITIES Discord: https://discord.gg/cs50 Ed: https://cs50.harvard.edu/x/ed Facebook Grou
