The world’s most popular online learning course, Harvard’s CS50, has been reborn in the ChatGPT era.
CS50, an introductory computer science course with hundreds of students on campus and more than 40,000 online, plans to use artificial intelligence to mark assignments, guide coding and personalize learning tips. It is said that
Maran’s energetic and engaging teaching style is known for transforming dry, introductory-level lectures on web development and software programming fundamentals into fun, interactive, exercise-filled classes. Despite having over 100 active teaching assistants, the growing number of students logging in from different time zones and with varying levels of knowledge and experience has made it difficult to fully engage. he said.
Maran, 46, said in a telephone interview, “With far more students online than teachers, providing support tailored to students’ specific questions is a massive challenge. ‘ said.
His team is currently fine-tuning an AI system to mark student work and testing virtual TAs to assess student programming and provide feedback. Instead of simply finding errors and fixing coding bugs, virtual TAs ask rhetorical questions and offer suggestions to help students learn, he said. Longer term, he hopes this will allow his human TAs 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 will enable more students to cheat and plagiarize without being noticed. was broken 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 Santa Clara, Calif.-based homework helper Chegg. The company recently reported that subscriber growth has slowed 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 is expected to grow to $348 billion by 2030, according to Grandview Research, 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 CEOs of major AI companies, including OpenAI and Alphabet Inc.’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 will ’embed’ privacy and ensure transparency in the data collection process. need,” he said.
