ITS not only provides students with one-to-one tutoring but also provides students with a STEM-based knowledge acquisition method. The interactive nature of the ITS enables the integration of teachers and students with resources. Through the review and analysis of relevant Chinese and foreign literature, a deeper interpretation of the birth and evolution types of ITS was carried out, and the theoretical basis and development model of ITS development was illustrated in detail. Under the background of the development of new-generation mobile network technologies and big data learning analysis technologies, ITS normalization construction includes four aspects: development path (wisdom learning), audience objects (diversity), learning mode (hybrid), and ontology evolution (smartness) Learning Assistant) and key development directions (education fair). In addition, with the advent of the “Creator” and “Internet Plus” era, the issues that deserve attention in the development of ITS include cultivating students’ innovative abilities, expanding students’ individualized learning, and realizing the development of thinking toward higher-order thinking.
