Intelligent tutoring systems (ITS) are computer programs designed to provide personalized instruction to learners. They use artificial intelligence to adapt to each student's learning style, pace, and needs, offering tailored feedback and guidance. This technology aims to enhance the educational experience by simulating one-on-one tutoring. These systems often incorporate elements of machine learning and natural language processing to analyze student performance and adjust the content accordingly. ITS can be used in various subjects, from mathematics to language learning, making education more accessible and effective for diverse learners.
