The Potential of Generative AI to Reform Graduate Education

Abstract

Graduate education is facing increasing criticism for lengthy timelines, high costs, and doubts about value. Master’s degrees take 1-3 years to complete, while doctoral degrees take a median of 8 years (NSF 2019). This prolonged timeline has significant opportunity costs, with graduates sometimes not entering the workforce until their 30s. The average cost just for tuition and fees is $30,000 for a master’s degree and over $55,000 for a PhD (NCES 2019). Moreover, criticisms have emerged about the relevance and rigor of graduate curricula, as well as concerns about mental health given the lengthy pressures of graduate school. Advances in artificial intelligence, specifically generative AI models, offer promising solutions to reform and streamline graduate education. Generative AI refers to machine learning techniques focused on generating novel, human-like content. This includes models like GPT-3 which can generate remarkably cogent text based on a few prompts. Recent research has begun exploring applications of generative AI in education. For instance, an AI system at Georgia Tech provided automatic feedback on short answer responses that matched the quality of human teaching assistants. Other studies have found generative AI can create reasonable first drafts for academic writing assignments. This paper specifically proposes leveraging large language models, a leading type of generative AI adept at producing human-like text, to reform graduate education. We outline four key applications: personalized learning, automated feedback, intelligent research assistants, and automated content creation. Personalized learning involves using generative AI tutors to provide customized pedagogy tailored to each student. Automated feedback means using generative models to rapidly provide detailed, individualized feedback on student assignments. Intelligent research assistants refers to applications like auto-generating literature reviews to assist student research. Finally, automated content creation involves leveraging generative models to produce teaching materials, reducing instructor workload. We hypothesize these applications could lead to better learning outcomes, higher satisfaction, and faster completion. With generative tutoring and feedback, students may comprehend material quicker and need less time to demonstrate mastery. Intelligent assistants could greatly accelerate early phase literature reviews and writing. Automated content creation could reduce the time instructors spend on lecture materials and assignments. However, care must be taken to validate quality and provide oversight. Over-reliance on generative models risks devaluing human aspects of education like critical thinking, curiosity, and interpersonal growth. Furthermore, AI inherently reflects biases and inaccuracies from its training data. In conclusion, this conceptual paper argues generative AI holds promise for reforming graduate education to be more efficient and personalized, if implemented cautiously and ethically. We aim to spark an important dialogue and debate on if and how these technologies could transform the next generation of graduate learning to be more engaging, effective, and empowering. Further research should continue exploring impacts on learning outcomes, optimal integration techniques, and mitigating risks of over-automation. With prudent design, generative AI could help graduate education evolve to meet the needs of a rapidly changing world.
