Adaptive learning systems are computer-based educational tools that use technology to personalize the learning experience for each individual student. They are designed to analyze data from student performance and modify instruction accordingly, providing customized instruction and support for each student. Adaptive learning systems can incorporate data from a variety of sources, including online assessments, textbooks, and student-generated content. They often use algorithms to adjust the instruction to the individual's learning needs, providing them with a more efficient and personalized learning experience.
