The world’s most popular online learning course, Harvard’s CS50, has been reborn in the ChatGPT era.
According to Professor David Mullan, CS50 is an introductory computer science course attended by hundreds of students on campus and more than 40,000 students online that uses artificial intelligence to grade assignments, teach coding, and The plan is to personalize learning tips.
Professor Maran’s energetic and engaging teaching style is known for transforming dry introductory-level lectures on web development and software programming fundamentals into fun classes filled with interactive exercises.

Even with over 100 physical teaching assistants, the increasing number of students logging in from different time zones and with varying levels of knowledge and experience makes it difficult to fully engage. he said.
“With so many more students online than teachers, providing support tailored to their specific questions is a massive challenge,” Maran, 46, said. I was.
His team is currently fine-tuning an AI system to mark student work and testing a virtual teaching assistant that evaluates student programming and provides feedback.
He said the virtual teaching assistant doesn’t just find errors or fix coding bugs, it asks rhetorical questions and offers suggestions to help students learn.
Longer term, he hopes this will allow human teaching assistants to spend more time in face-to-face or Zoom-based office hours.
The effort comes at a time of growing concern among educators that technologies like ChatGPT could allow more students to cheat and plagiarize without detection. rice field.
Some public schools and colleges around the world ban it.
The rise of AI has also hit the stock prices of online education businesses such as California-based homework helper Chegg. Chegg recently reported that subscriber growth is slowing as people try out free chatbots created by OpenAI.
Maran said CS50’s use of AI could highlight its benefits in improving the quality and access of education, especially online learning. The industry expects Grandview Research to grow to $348 billion by 2030, nearly tripling from 2022.
“Potentially, AI offers great potential in education,” he said.
Originally a single introductory class on computing, CS50 has evolved into multiple classes, with 1.4 million YouTube subscribers and branded merchandise such as stress balls and t-shirts.
Over the years, over 4.7 million people have enrolled in this course. It is now available as part of edX, a digital learning platform created by Harvard University and the Massachusetts Institute of Technology to offer college-level courses in a variety of subjects online.
However, some experts caution against using AI when it is still in its infancy and prone to errors.
Earlier this week, the chief executives of major AI companies, including OpenAI and Alphabet’s DeepMind, issued statements warning of the “risk of extinction” from AI.
Others said its use in education poses ethical risks, especially when collecting data to personalize lessons.
Emma Taylor, an analyst at London-based consulting firm GlobalData, said: “To ensure student privacy, platforms need to ’embed’ privacy and ensure transparency in the data collection process. there is,” he said.
