Metaliteracy is the basic ability to improve all literacies. In the current pluralistic social situation, the cultivation of metaliteracy has become the fundamental goal of educational activities. In order to further clarify the current situation of the cultivation of metaliteracy in the educational activities of public libraries, 1214 educational activities conducted by public libraries in 13 cities of Jiangsu Province in recent 5 years were collected, and the content analysis and grounded theory methods were conducted to code the data. This study revealed the support and cultivation status of public library education activities in the four dimensions of metaliteracy goals: behavior, cognition, affection and metacognition. According to the relationship between metaliteracy goals and multiple activity elements, three typical modes of current public library education activities were identified, which are cognition-oriented humanistic and artistic activities, affection-oriented humanistic and artistic activities, and behavior-oriented technical and skilled activities.
