【英文摘要】：
Automatic evaluation and adaptive feedback of virtual science inquiry learning are important supporting means to improve the effectiveness of inquiry learning. Firstly, this study outlines the application status of intelligent technology in virtual science inquiry learning from three aspects, namely, the element representation and analysis model, the automatic analysis and real-time evaluation, and the adaptive feedback. And this study summarizes the practical challenges faced by the current application of the technology, such as the difficulty in deeply exploring the element representation, portraying uncertain inquiry processes, and generating adaptive feedback. Secondly, on this basis, three key technologies are proposed: the construction of underlying computing model based on activity flow, the dynamic monitoring and automatic evaluation of complex inquiry process, and the generation of self-adaptive feedback content with explainable attribution. Thirdly, based on the key technologies, a technical architecture of the independent inquiry learning platform for virtual science experiments is designed. Finally, the study summarizes the innovation of the current research and puts forward future suggestions to provide a useful reference for further technical exploration in the field of virtual science inquiry learning enabled by intelligent technology.
