Harvard's Computer Science 50 (CS50) course is set to undergo a significant transformation by integrating artificial intelligence (AI) chatbots into its teaching method. Students will have the opportunity to utilize AI to help identify coding bugs, receive feedback on their program design, clarify unfamiliar lines of code, and get personalized answers to their questions.
Preparing Students for the Future
CS50 professor David J. Malan stated that this approach represents an evolution of their tradition of incorporating software into teaching. The aim is to create an environment where each student can benefit from an almost 1:1 teacher-student ratio, leveraging AI-driven tools to support learning around the clock, in a manner suited to each individual's pace and learning style. The CS50 team is reportedly experimenting with GPT 3.5 and GPT 4 models for this purpose.
A feature called "CS50 bot" is in the pipeline, designed to respond to frequently asked student questions on the Ed Discussion platform, a popular discussion board software used for STEM classes. The AI-generated responses can be subsequently reviewed by human staff members, ensuring the accuracy and relevance of the responses. A beta version of this feature is currently under testing for the summer school version of CS50.
Cheating Concerns
Professor Malan noted that AI programs, like ChatGPT and GitHub Copilot, can sometimes be overly helpful. The plan for CS50 is to leverage AI in a way that it guides students towards solutions rather than directly providing the answers. The AI tools will help students find bugs in their code and translate complex error messages into simpler, student-friendly language.
However, the introduction of AI also raises concerns about academic integrity, as it can potentially facilitate cheating in a more anonymous and scalable manner. In response to this, Malan emphasized the importance of teaching ethics within the course, enabling students to responsibly navigate the incorporation of AI.
Broader Impact
The plans to integrate AI into CS50 extends beyond the Harvard campus. The course is also available on edX, an online platform co-founded by Harvard and MIT, which made the course accessible to a wider audience. Professor Malan mentioned that one of the ongoing challenges has been providing personalized responses to students' specific questions on such a large scale. The new AI features will address this issue, benefiting both on-campus and online learners.
Automating Grading
The AI integration into CS50 also has the potential to alleviate the workload of the course staff, who have been grappling with the challenge of grading efficiently. The introduction of AI could significantly reduce the time spent on qualitative assessment of students' code, allowing teaching fellows to spend more meaningful, interpersonal time with their students.
Hidden Benefits
While Professor Malan acknowledges that early AI iterations might underperform, he regards this as a vital part of the learning process. This presents an opportunity for students to enhance their understanding by critically analyzing the AI's responses and their own work. Interacting with these imperfect systems also bolsters their problem-solving skills. Simultaneously, it cultivates a more discerning approach to AI, which is important as these tools become more prevalent.
