Using AI as a Personal Tutor - CS50 Lecture in Seattle with Prof. Malan

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, an entertaining presentation, plus an opportunity to ask your own 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.
