  With the development of artificial intelligence, personalized learning has
attracted much attention as an integral part of intelligent education. China,
the United States, the European Union, and others have put forward the
importance of personalized learning in recent years, emphasizing the
realization of the organic combination of large-scale education and
personalized training. The development of a personalized learning system
oriented to learners' preferences and suited to learners' needs should be
accelerated. This review provides a comprehensive analysis of the current
situation of personalized learning and its key role in education. It discusses
the research on personalized learning from multiple perspectives, combining
definitions, goals, and related educational theories to provide an in-depth
understanding of personalized learning from an educational perspective,
analyzing the implications of different theories on personalized learning, and
highlighting the potential of personalized learning to meet the needs of
individuals and to enhance their abilities. Data applications and assessment
indicators in personalized learning are described in detail, providing a solid
data foundation and evaluation system for subsequent research. Meanwhile, we
start from both student modeling and recommendation algorithms and deeply
analyze the cognitive and non-cognitive perspectives and the contribution of
personalized recommendations to personalized learning. Finally, we explore the
challenges and future trajectories of personalized learning. This review
provides a multidimensional analysis of personalized learning through a more
comprehensive study, providing academics and practitioners with cutting-edge
explorations to promote continuous progress in the field of personalized
learning.
