Computer Science with Theatricality: Creating Memorable Moments in CS50 with the American Repertory Theater during COVID-19 Paper at https://cs.harvard.edu/malan/publications/V1fp479-malan.pdf.

But a silver lining of that time was unprecedented availability of space on campus, including the university's own repertory theater. In healthier times, that theater would be brimming with talented artisans and weekly performances, without any computer science in sight. But with that theater's artisans otherwise idled during COVID-19, our introductory course, CS50, had an unusual opportunity to collaborate with the same. Albeit subject to rigorous protocols, including face masks and face shields for all but the course's instructor, along with significant social distancing, that moment in time allowed us an opportunity to experiment with lights, cameras, and action on an actual stage, bringing computer science to life in ways not traditionally possible in the course's own classroom. Equipped with an actual prop shop in back, the team of artisans was able to actualize ideas that might otherwise only exist in slides and code. And students' experience proved the better for it, with a supermajority of students attesting at term's end to the efficacy of almost all of the semester's demonstrations. We present in this work the design and implementation of the course's theatricality along with the motivation therefor and results thereof. And we discuss how we have adapted, and others can adapt, these same moments more modestly in healthier times to more traditional classrooms, large and small. *** TABLE OF CONTENTS 00:00:00 - Computer Science with Theatricality 00:02:32 - Acknowledgements 00:03:08 - Tearing a phone book to explain binary search 00:04:50 - Opening doors to explain linear and binary search 00:06:29 - Glasses of water to explain swapping variables 00:07:45 - Mailboxes to explain pointers 00:08:15 - Refrigerator and milk to explain race conditions 00:09:48 - Other memorable moments 00:11:03 - Results 00:13:42 - Future work 00:14:07 - Conclusion 00:14:35 - End credits *** This is CS50, Harvard University's introduction to the intellectual enterprises of computer science and the art of programming. *** HOW TO SUBSCRIBE null 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 Group: https://www.facebook.com/groups/cs50/ Faceboook Page: https://www.facebook.com/cs50/ GitHub: https://github.com/cs50 Gitter: https://gitter.im/cs50/x Instagram: https://instagram.com/cs50 LinkedIn Group: https://www.linkedin.com/groups/7437240/ LinkedIn Page: https://www.linkedin.com/school/cs50/ Medium: https://cs50.medium.com/ Quora: https://www.quora.com/topic/CS50 Reddit: https://www.reddit.com/r/cs50/ Slack: https://cs50.edx.org/slack Snapchat: https://www.snapchat.com/add/cs50 SoundCloud: https://soundcloud.com/cs50 Stack Exchange: https://cs50.stackexchange.com/ TikTok: https://www.tiktok.com/@cs50 Twitter: https://twitter.com/cs50 YouTube: null HOW TO FOLLOW DAVID J.
