Prof. David J. Malan: Using AI as a Personal Tutor - In-Person!

Please join us for a look at how CS50 has incorporated Artificial Intelligence (AI), including its new-and-improved rubber duck debugger, and how it has impacted the course already.  🦆 CS50 is Harvard University's introduction to the intellectual enterprises of computer science and the art of programming, freely available as OpenCourseWare, with more than 7M registrants at cs50.edx.org and 2.2M subscribers at YouTube.

Using AI as a Personal Tutor

 • How do we approximate a 1:1 teacher-to-student ratio through software?

 • How can we equip students with a subject-matter expert by their side at all times?

 • How can we guide students toward solutions rather than offer solutions outright?

 • Please join us for networking, socializing, and an entertaining presentation

 • Bring your questions!

  

In Summer 2023 and Fall 2023, Prof. Malan and his team actively tested an AI-powered chatbot, implemented as a virtual rubber duck (a la rubber-duck debugging), developed specifically for CS50.  The CS50 Duck (aka CS50.ai) was first deployed to approximately 70 summer students, then to 1,000's of students online, and finally to approximately 500 on-campus students.  Prof. Malan will discuss the development of CS50.ai, detailing the challenges faced, solutions proposed, and results achieved, all toward realizing a long-held aspiration: a 1:1 teacher-to-student ratio.

  

Who’s Invited:

 • Harvard undergrad & graduate alumni

 • Ivy++ (Stanford, MIT, Wharton, Booth, Columbia, Oxford, Cambridge, etc.)

 • Your guests
