Teaching CS50 with AI - David J. Malan

- 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. 🦆
Paper at cs.harvard.edu/malan/publicat....
Slides at docs.google.com/presentation/....
In Summer 2023, we developed and integrated a suite of AI-based software tools into CS50 at Harvard University. These tools were initially available to approximately 70 summer students, then to thousands of students online, and finally to several hundred on campus during Fall 2023. Per the course's own policy, we encouraged students to use these course-specific tools and limited the use of commercial AI software such as ChatGPT, GitHub Copilot, and the new Bing. Our goal was to approximate a 1:1 teacher-to-student ratio through software, thereby equipping students with a pedagogically-minded subject-matter expert by their side at all times, designed to guide students toward solutions rather than offer them outright. The tools were received positively by students, who noted that they felt like they had "a personal tutor.'' Our findings suggest that integrating AI thoughtfully into educational settings enhances the learning experience by providing continuous, customized support and enabling human educators to address more complex pedagogical issues. In this paper, we detail how AI tools have augmented teaching and learning in CS50, specifically in explaining code snippets, improving code style, and accurately responding to curricular and administrative queries on the course's discussion forum. Additionally, we present our methodological approach, implementation details, and guidance for those considering using these tools or AI generally in education.

This has to be one of the best teachers in the world.
Actually all teachers of CS50 🥳🥳🥳
they are
Thats why he works where he works lol
I really enjoy asking the AI general questions to get a better grasp on the more confusing concepts!
I finally had a chance to watch this presentation in it's entirety and I'm grateful for it. Thank you David. Oh, and I also look forward to watching the Duck Debugger evolve.
Impressive, thank you all cs50 Prof, staff and community. You are awesome
it’s actually wonderful. totally changed how i think about learning
Thank you for the awesome content!! Love you guys!!
Genius! the ideia of Rubberduck amulet is great.
Great video. I liked the idea of design50. I offen ask the rubber duck AI in order to improve the design. It is great help in the course and it improves learning by a lot at least for me.
It is unbelievable how awesome the cs50 is. You at cs50 are doing great job.
thank you very much David!
I find that a chatbot is not too helpful per se, but simply going through a session of questions and consideration of the veracity of the answers from a chatbot, prompts my thinking about a problem.
Thaks for opportunity!
David é daora. Ele consegue fazer de CS algo entendível. So glad and looking forward to make CS50w soon.
Amazing idea!!!
Great pedagogy
Nice one
OMG GOOD JOB !!!
Dear Mr.Malan, Kindly, can you give the Gpt lecture of Prof. Rongxin Liu as text. :) Thanks !
This is really exciting, but I can't find the VSCode extension with AI? Is there a way to get the working version that is demonstrated here? I would be happy to plug in my API key.
Nice! 😀👍
Best teacher ever,
Five point seven million are going to Harvard for free thanks to this man. I have been visiting this course since 2013. Still no certificate. If you cheat you have not understood the lesson. I will soldier on.
I also just talk to it, its nice...
Me wondering why is the profile photos of CS50's social media account a cat instead of a duck?!
I suppose that if you attend Lecture 2 of CS50's.Py (which is about Loops) you will have an entertaining epiphany about your question.
45:26 omg he's talking about me
Hi, what is after CS50?
I cannot believe this isn't called QuackGPT
Where do i access this full course from ?
just follow the link shown in the video in the beginning
There are two ways, In-Person and Virtual, the first is obviously on campus, while the second can be accessed from the EdX website (you find the link in the video description) where the different CS50 courses are.
🖤
Givin' a cuack!
❤
Why is it called cs50 and not cs60 cs70 what does 50 stNd for
5 because course’s penultimate digit signifies its “course grouping” per the Harvard College Handbook for Students (where 5 go for Programming Languages) and in CS, courses numbered < 100 are primarily for undergraduates

Hello
Hey
I remember when you claimed that use of AI in our studies was actively prohibited.... I tried discussing the idea that it's a useful tool which will be used in the industry, and comments were abruptly closed to avoid that discussion - with mention made specifically about my comment...
Nice to know I was right all along :)
In your very first example at 22:55, your AI is already serving up lies and nonsense. It's not actually true that Flask "does not require particular tools or libraries" - the Flask docs tell you in the second paragraph that it relies on Werkzeug, Jinja and other libraries.
Yes, llms hallucinate, yes you need to use common sense when using them but nontheless they are a great asset
Ola
is it possible to speak in a bit more calm manner? Not sure if its just me but listening to you speak i see its very fast and also very high energy output as if you’re shouting all the time. Thanks for the video.
You are free to make the video at a slower speed . I use this way many times.

Hi
AI made it clear that python is the only language which can run!! 😄
Should teach how to use the AI in the most effective way, where and why to use it and not use it. Rather than just stop people asking questions at a number of questions that just seems too much.
Business though comes in way
I have a few issues with that suggestion.
First, this is the CS50 rubber duck AI, if you learn how to use that, might not be too useful on a different one.
Second, people still have to be able to do things without AI, since they still have to figure out whether the AI is telling them BS. AI can support, but you shouldn't completely outsource thinking.
Third, CS50 tends to focus on fundamentals that don't change over time, while for AIs, the recommendations change all the time. For example, for the first available ChatGPT, people suggested short prompts crammed with information. Current models with their larger context window do way better if you talk as naturally as possible.
Duck should be written in plain language.
wrong! we are not 600-800 students, we are over 1 000 000
I found frustrating that copilot and others dont let you reason
David J. Malan, did you think a "pre-trained expert system" better than a teacher? something wrong here!!!
He’s talking much too fast it’s disturbing.
agree
no，not fast at all
do not try 2x speed
Why didn't i find out about this at the beginning of the semester 🥲
